"three thirty four meter" Discussed on SpaceTime with Stuart Gary

"Of the voyager two spacecraft. The agency's seventy mehta camera deep space network radio dish. The only antenna capable of contacting the forty three year old spacecraft successfully set a series of commands to the probe the dish officially known as deep space station forty three has been undergoing a major upgrade and refurbishment since mid march with the dish out of action mission managers could receive data from voyager two through the three thirty four meter wide radio antennas at the camera complex but couldn't send commands to the far-flung probe which is now lift our solar system and he's flying through interstellar space among the upgrades to the ds's forty-three dish with tinny radio transmitters one of them which is used to talk to void you to hasn't been replaced in more than forty seven years engineers have also upgraded heating and cooling equipment for the electronics. The power supply equipment and other technology needed to run the new transmitters. The successful cold avoid the to is just one indication that the dish will be back online showed in february next year located knee camera. The antennas part of a network of three radio antenna ground stations. The other two being goldstone in california and madrid in spain the network up primarily used to communicate with spacecraft operating beyond earth orbit the position of the three facilities around the planet ensures that almost any spacecraft line of sight with earth can communicate with at least one facilities at anytime voice to is a rare exception launched in nineteen seventy seven just days before its twin void you won the spacecraft was designed to achieve nothing lists than the grand tour of the outer solar system visiting the gas giants jupiter and saturn and the ice giants. You're innocent neptune. In order to make it close fly. By of neptune's moon triton in one thousand nine hundred nine the probe flew over the planet's north pole the gravitational impact of that dejected deflected it southwards relative to the plan of the planets. And it's been heading in that direction. Out of the solar system and interstellar space ever since now more than eighteen point eight billion kilometers from earth the voyager two spacecraft e so fast south it no longer has line of sight with radio antennas in northern hemisphere. So this is forty. Three's the only dish in the southern hemisphere with a transmitter powerful enough and that broadcasts at the right frequencies to send commands to the distant spacecraft voyages fast moving twin void. You one took a different path past satin and can communicate through the antennas at the to dsm facilities in the northern hemisphere. The antennas need uplift commands to both voyagers in radio frequency range code s band and the antennas downlink data from the spacecraft in a range known as the x band. The probes are constantly sending back science data from interstellar space that is the region of the galaxy immediately outside the sun's helius fear. The protective bubble of product was a magnetic field created by the sun that surrounds the pilots and the copperbelt a collection of small icy bodies beyond the orbit of neptune. This forty-three began operating back. In one thousand nine hundred seventy two five years before the launch of the voyage attune voyager one spacecraft back then. It was only sixty four meters wide the same size as the packs radio telescope dish. It was expanded to seventy meters in nineteen eighty seven and received a variety of upgrades and modifications since then the is overseeing the counter. Work say this is being one of the most significant makers the dishes received and the longest. It's been off line in thirty years. Philip baldwin operations manage if nasa space communications and navigation program says the assist forty-three antenna is a highly specialized system. He says there are only two other similar. Antennas in the world so having the antenna down for a full year's not an ideal situation for voyager or any other major s emissions currently in operation. The camera deep space. Communications network complex is managed by the ceasefire siro on behalf of nasa complex spokesperson. Glenn nagel says. The refurbishment of dc's forty-three will benefit other missions including nasr's mars perseverance rosa which will land on the red planet on february eighth next year. And the upcoming optimists missions which will return humans to the surface of the moon. Twenty twenty four and eventually onto mars part of the ongoing upgrade. Or how big seventy made a dish one of those with that that we could send commanding through the voice of food place craft that again tenant they spray the only intern around the world have bullet doing and why is it. The anyone that can reach voyage to avoid you just space craft and kind of neptune back in nineteen ninety nine. Victory took southwood below the ecliptic plane. And so come now by. Yeah the in out there in california literally. The earth is in the waste so they're able to see that by take the thirty four dishes simply aren't big enough not capable to transmit with high power transition type ability like still can receive if we combined two of them their data from georgia to we've still they never for the last eight months that we've been off line since manning's so now it's forty three half the facts online speaking send those bottled commands again. And what was the refurbishment done to the big dish joining upgrade equipment that has been operating on ten and a further four years. But some of the transmitters were in that device group. And i desperately need all been up right so we built two new high palestine's minutes to the dinner. One of those needed for the void vice crop other it will be used for future missions of mazar humans to the moon and so on and also played electrical pride house cooling systems Refurbishment of the pedestals basically a top to bottom inside out an afraid of the ditch. And what. People don't often realize especially australian listening. Because i hear a lot about the cease iras pox radio telescope the sixty four minute dish. They this was actually bigger. The given bill affecting station is the largest in southern hemisphere. Seventy majors in about the twenty two story building and just the dish moving structure. Why some full thousand. Tom physically moods with position. Any quietness guy communicate. Spice pops hundreds of millions billions of kilometers. Why is the refurbishment process of big job has been the entire project is eleven months for the upright. Does the end. Santa the eight months which might be named tactic by things like sizes and other bush flies. Taxes of twenty twenty Has entailed a hundred and fifty people different contractors around engineers technicians expert. Coming out from the pulsing labs in pasadena california. Polls do this work on this. Really great workforce of the nation. How big dishes hambro now. Literally this sort of thing have been working dying not seven days a week. They get the antennas where it is now and so also make sure complete. Do back online. I already to joke with some of the missions. Bribing mas in february next year to get those next few months already because perseverance just past the halfway mockup beliefs. Yes that's correct so we continue to track on own journey. Demand north side of the nodded arab emirates missions. Pope this is also going to miles around the same time period planning on the surface. Tell us about tidbinbilla old. The digs network camera station as as nasa coolest. The camera date by communication complex. Of course is part of nafta states by three stations around the planet that probably about the will the provide twenty four seven communications. They're all dozens of robotic missions that are solar system folks when we talk about where we're talking about things hundred thousand kilometers and beyond so there are networks handle the much closer stops and there's been satellites and she a stationary stuff like really candle. Everything else but you is now backyards so like the i have these antennas around.

"Show when you don't have to be a rocket scientist to understand the latest news about space and related subjects. My name is Stephen Hackett. I'm joined is always by my co Jason. Snow are Stephen. Hello Jason Good. Be Back as always to talk about space so many things somebody spacecraft. Somebody would be spacecraft. That's pretty much the whole show this week. I think yeah pretty much pretty much. There's a lot going on in space. Unlock going on on earth of stuff that is supposed to go to space. Let's talk about one of those. So the Mars Twenty Twenty Rover. Then have a name for a long time. Nasa held this really wide reaching. I don't Wanna say competition but competition to name the rover and as of last week. It has a name so ours. Twenty twenty is now known as perseverance. I think is an excellent name. Yeah that's my my take on the name. That's good name. Fits in with the theme right. We've had spirit and opportunity and curiosity right so it fits in there. Yeah and those also had their names chosen by students. What is really cool so this competition was open to to students. You and I put. Our Name came from school age children and the winner. This time was a seventh grader. By the name of Alexander Mathur from Virginia. His name was with multiple rounds so they had like forty seven hundred volunteer judges teachers professional space enthusiasts. They're viewed the submissions that narrowed the pool down to one hundred and fifty five and then down to nine and in the public could vote on those. And after seven. Hundred seventy thousand votes The results were submitted to NASA for consideration. You don't AEROBIC AEROBIC MIC rover. Face situation exactly. You don't want that. They don't want that everyone's learned their lesson about letting the Internet name things and perseverance was chosen which I think is fantastic. It's good name. Fits with the theme and So we'll talk about hopefully everything works out. Perseverance scrambling around on the surface of Mars. And like we said. Alexander's seventh grade in Virginia and he became a space enthusiast through attending space camp in Huntsville. Which I've not been to space camp but I've been to where they hold it and it's awesome. He saw the Saturn five on display there. And there's this quote that NASA has of him saying this is a chance to help the agency that put humans on the moon will soon do it again. This Mars rover will help pave the way for human presence there. I want to try to help in any way that I could. Refusal of the challenge was not an option. That's awesome you. Want to tell us about. Voyager yeah so voyager two. We talked about actually two episodes ago. We talked about how voyager two had a little problem It had like a partial shutdown reset it and fix it. It's amazing remember keeping in mind that this is a space probe. It's been in space for forty three years. It's eleven billion miles from Earth but we still keep tabs on it. It's still teaching US things. Its primary mission long since complete a flying by planets in the solar system. But it's still teaching US things about the outer solar system and the edge of the sun's influence in interstellar space will keep it going. There's a there's a small team that works on it And it had this prob woman and a fixed it. But what's interesting is we're not going to be able if it comes up with other problems to fix them for a while because of how we communicate with space probes which is actually kind of an interesting thing to think about like. How do we communicate over these long distances and the answer is we have really big powerful antennas to send and receive from far out in space? It's called the deep space network. It's generally what's used to talk to. Space probes all over the place. They are the most powerful radio. Antennas in the world There are three locations which with multiple antennas at each location. Goldstone in California Canberra Australia and Madrid in Spain We've been using the deep space network. Ds N To communicate for fifty seven years it's used by NASA ESA and several other international agencies. I think that that new Mars probe that's coming from what is it the UAE. In if that's going to launch a twenty twenty it's also using this like all. A lot of international agencies at each station is three thirty four meter antennas and one Gargantuan seventy meter antenna and there's actually a pretty cool website you can go to the DSM now website NASA. And you've probably seen this if you've been on space twitter at all people linked to this all the time. It is a really cool site that actually shows you all of the dishes all of the antenna and who they're communicating with like in outer space. You see all four at each location. But if you go there now you'll discover. Is that the big dish in? Canberra is great out. It's faded away. And why is that? The answer is in Tennessee maintenance. And in fact it's more than that as we just mentioned. Mars twenty twenty three of the four Mars missions that are planning to launch. This summer are gonNA use the deep space network. Only China is using. Its own antenna to communicate. And what that means is they want to do some maintenance on the deep space network before that happens before those Mars missions reach Mars and they need to do maintenance on the seventy meter dish at Canberra but because of where voyager two is if you've ever wondered where Voyager Two is relative to Earth. The answer is it's Kinda down because only Canberra's dish can see it. So that's the direction. Voyager two is it's an area of space that's only visible from the Southern Hemisphere. Not from Madrid or Goldstone and so If they're GonNa Fix Canberra's twenty meter or seventy meter dish. They can't talk to voyager and that that for the next eleven months. We won't be able to send messages to voyager. Although the smaller antenna at camera can receive messages from Voyager. So what it means. Is that the voice. Your team has to keep cross. It's fingers a little bit. Hope that nothing really bad happens Hope IT keeps itself oriented properly with its antenna pointing back at the earth. I didn't actually know this. But Voyager to to this day has to fire thrusters more than a dozen times a day. Just little tiny bit just to make sure that it stays properly oriented and its onboard automation to handle the orientation process but it has to work correctly and if something bad happens something goes wrong. There's nothing the voyage your team can send to the spacecraft to fix it so they will just have to watch and wait and hope although can still get data back. So it's a probably nerve wracking Almost year for that voyager team although they can still receive messages but this is also something that we need to do in terms of maintenance because these antennas are what we used to talk to. All you know all of the spacecraft NASA and Esa in many other countries. And if you haven't been to that page before it is a lot of fun to watch as new craft go up there. You can actually go to that page and see you know. Where are we communicating with the you know the current Mars rover or one of the Mars? Orbiters or you know if there's something on the moon you know are are. Are we communicating with that or are we talking to something in the outer solar system all of that information is there like new horizons data? You'll find out where that's coming down if new horizons is talking so these face network needs to be updated. That sounds good but it is going to be this silent period for voyager two in terms of like it won't hear from us. I'm sure that is a little nerve racking for the voyager team but the spacecraft has behaved well for really long time and hopefully it continues to do so during this This downtime yeah. We'll cross our fingers for Voyager. It is forty three years in space. Pretty impressive. Pretty Amazing. Very impressive Let's switch gears. A little bit and talk about SPACEX. So there's a couple of stories here One you may have seen a couple of weeks ago pictures of a blown-up prototype in the Texas desert. Where Elon Musk and SPACEX or building pressure vessels in progress of the starship hardware that they're putting together they're doing all this prototyping and they had S In one which was this ruptured tank. It kind of went off and they think it was due to bad welds on the tank. And so this is all going on and Eric of our San Diego. Actually what a Texas interviewed at SPACEX and historian simply amazing. And you should definitely go read it. But it seems like spacex in this team in Texas are just burning the candle at both ends to get starship. Prototyping and construction underway historian opens with this. This crazy picture of musk holding a meeting at one o'clock in the morning to approve a bunch of hiring and then by the end of the next day they'd hire two hundred and fifty people from the local area. Yeah it's pretty wild right real wild. That was a story with Tesla years ago. Their so called production hell. Musk was just like sleeping on the line. Trying to figure out all of its automation and stuff and it seems to be that. He's repeating that here now with spacex but there's also the story an article about the S. and once that task bed that had exploded on the stand again. It's a pressurization tank so it's holding really cold liquid oxygen and has taken in this case and it had ruptured and they were meeting about that and some engineers sort of voice will. We were worried about it but we did the test anyways you know. We were told to keep moving forward and Musk said. Engineer didn't fill her to contact him directly by all accounts he seems to be on the premise. Basically nonstop right now. Yeah there in Texas trying to get this moving because he wants to build a production line for starship hopefully building one a week and then one every seventy two hours yep. Ll Musk time but clearly. The company is moving quickly in this development stage. Yeah Elon Musk. That's a lot of things but is space. X has proved to be quite impressive with what it's able to do even if that is not. I think there's a. There's a factor of this that is. I'm GonNa ask for everything and then you're going to give me a lot and that's what I want is a lot you know. He's he's overdoing it here. A little bit but I think it's interesting that you know in saying if you think there's a reason that this isn't working come talk to me that you know we don't want a a culture here where we we know there's something wrong and we go ahead anyway because that's a bad idea but he also is definitely you know trying to cultivate a culture of Not being failure averse right like he wants them to be smart. But it's okay of stuff breaks so If the first Starship blows apart. You know we WANNA know why and that might not have been good reason but they've also got another one coming and this is how you learn and all of those things so I think a fascinating right to see him. How do you? How do you get a project off the ground literally off the ground? Yeah IT'S PRETTY. It's pretty wild and it's a it's all kind of building on his whole thing of we want to get to Mars. We want to put people on Mars and he sees the starship needing a whole fleet of them to make that possible. And even though it's very early days I mean again. They're just testing pressure vessels. And they're coming up with new ways to wealth things. They're working on this machine to make the welding more or I guess. More consistent across multiple finishes like all the stuff got the the welding Zipper machine fam- inventing and all that it's it's cool. It's it's it's a great article it really is like so visited. Elon. Musk and Texas. And this is what it's like and it's it's it's very good. It's easy to look at this and think well musk's sort of out there on a limb with this and something to be said for that but like you said they have a proven track record at this point and I just keep thinking about this in conjunction or I guess in conjunction to you but in contrast to the SOS which has moved very slowly for a whole lot more money and how different the two programs couldn't be more different. I think for sure and that just really really is interesting to consider when you think that starship some point we'll be put into service and NASA will polly by flights on it. It's like well it's comes from a different place than Nassar's in hardware hip to while everyone's in the desert building rockets in the middle of the night. So what we're saying and blowing them up repeatedly but it's how they did. That's how the Falcon came to be right. They were on an island and tried to launch them and finally the last one worked and and here we are in fact in conjunction with the story. There's another story about SPACEX that Over the weekend it had a successful launch. An International Space Station resupply mission. It was its twentieth successful resupply mission and it was the fiftieth landing of the Falcon nine. Putsches I mean I remember the first one right now fifty and it's it's almost routine thing that people talk about with space space not routine and yet to make it look routine to have gone through fifty of them. It's still amazing. I still like to watch it every single time. But the fact that there are fifty first-stage landings that they've done crazy. It is crazy it was also the last launch of the Dragon. One capsule they'll be using dragon to moving forward which is very similar to the crew. Dragon Council for yeah commercial crew. It's based on the same same platform it comes with revised Parachute System. Twenty percent greater cargo capacity.

"three thirty four meter" Discussed on The Invisible Network

"NASA missions to Mars had done their jobs providing NASA with an understanding of the Martian terrain our astronauts will encounter rather. I'm curious about a more limited reconnaissance one trapped between the waking speaking world and a dreamlike tomorrow when NASA communications engineers look at the vast topography of Mars this dusty celestial stranger. You're what sort of networks do they map onto. It's barren surfaces. What follows is an interview with Joseph Laszio chief scientists of the Interplanetary Network Network Directorate at the Jet Propulsion Laboratory which manages Nastase Deep Space Network? The Deep Space Network is a collection of three ground stations with massive passive antennas strategically placed around the globe to communicate with spacecraft almost anywhere in deep space the network ensures communications for many lunar missions ends with Mars with the voyager missions beyond the influence of our son and many other spacecraft. I've asked Lasi about innovations and technologies that will enable Carr's immediate goals in deep space. But I've also done some reconnaissance. I've asked him to stretch his imagination into the far future plumbing. His imagination Asian for what a Martian communications network might look like hundreds of years from now enjoy. What is your name your role at? Jpl My name. Is Joseph Law Zeo. Although almost everybody knows me as Joe and my role at JPL is. I'm the chief scientist of the part of of JPL called the Interplanetary Network Directorate and among other things we managed NASA Deep Space Network for NASA. What does that role entail Fascinating diversity of projects the Deep Space Network Doc. As as we'll discuss momentarily is responsible for enabling us a whole suite of missions both for NASA and for International Space Agencies. He's and so I think about all aspects of how can we get more science Either from the spacecraft missions or from other things with with the the antennas in the Deep Space Network and what role and to JPL. It was a it was an opportune time I my background is radio. Astronomy Ronnie and the deep space network. The foundation of the deep space network is a series of large essentially radio antennas and in the past if they have done working in radio astronomy so that influence of knowing some aspects about radio technology radio frequency technology. Some the possible science applications and then just Looking to the future possible projects that at the time. JPL was contemplating be involved in so on a on a basic level. What is the deep space network? What does it architecture look like? The deep space network is the set of currently radio. Antennas that NASA NASA uses to enable a whole suite of missions across the solar system and beyond there are three complexes of antennas One is is located in Goldstone. California which is maybe a third of the way between Los Angeles and Las Vegas One is located in Madrid just outside outside Madrid. Spain and one is located just outside Cambra Australia Each complex has four antennas us one very large seventy meter antenna and then three relatively smaller thirty four meter ties But even thirty four meter antenna. If you've ever stood next to one it's it's an impressive piece of engineering machinery. And these these complexes are set up. They're almost equidistant in longitude so each was about one hundred twenty degrees apart Which means that no matter where a spacecraft is in the solar system it can always see Out least one on. ESPN TANA for receiving commands from earth and then transmitting data. Back and what sort of missions does the network currently support indicated it supports Abel's missions everywhere across the solar system. And in fact if you if you simply do a web search on DS and now now there's a website that allows you to view in real time. What date are coming down or what commands are being sent up from various base crop up looking at speak and just to give you ample of the suite of of missions that is is enabled by the Sun in Madrid there is is Data be coming down from Soho which is a joint European NASA mission to study the Sun there are data coming down from Juno which is the spacecraft orbiting Jupiter at Goldstone Currently Mars is overhead at Goldstone so there are two antennas. Actually that are hi. There transmitting commands or receiving data from four different spacecraft for landers at Mars There's also a data coming down from Sean Ryan to. which is the Indian mission at the moon and Canberra Dare coming down currently from Voyager. Two which is actually actually spacecraft outside the solar system and It's actually coming down to seventy meters so it's an illustration of just how how much science the the network enables so. That's a lot of different missions. What sort of services do you offer them the DSM it provides three essential capabilities? They go by the names telemetry tracking and command often. Because it's NASA of course we need a acronym so often abbreviated to TNC PNC Telemetry is the Thing about which most people probably Have the most direct connection so you've ever seen a picture sure of planet. Undoubtedly that picture has come down through one or more antennas in the network and telemetry is that process in which the spacecraft transmits a signal or transmits data or an image from its Antenna from its system and then it's received by one or more DSM Benintendi so the telemetry is when the spacecraft sends data down to the earth down to US command. The C part is when scientist inches stir operators on the ground are sending commands up to a spacecraft to do something Take a picture. Gather some kind of data change its trajectory slightly lightly and then finally tracking the Middle T. is for trying to figure out where the spacecraft is on this guy or where the space craft is in space at and of course this is a particularly essential aspect with spacecraft is going from Earth to a destination we want to keep it on track as it were and the and ensure that it's actually going along the trajectory that will get it to its intended destination. And how is the network growing support the optimist missions to the Moon in the near your term One of the plans or actually the plan is for the network to continue to expand. As I said earlier. There are one. There is one seventy wendy meter at each complex and then three thirty four meter antennas each complex and the objective is to continue to build out thirty four meter. Antennas Antennas over the next five years so that each complex has four Thirty four meters in fact there are two thirty four meter. Antennas antennas currently under construction at Madrid In various states state construction and then there are there is one planned at Goldstone own for which construction will be starting relatively soon. They're already doing site surveys. Trying to figure out exactly where Next to the other three thirty four meters the fourth will go. And there's a plan for th one four Canberra Sort of middle of of next decade in the middle of the twenty twenties and we fat. Then there'll be numerous thirty four meters which will allow very high data rates down from The space craft at or on the surface purpose to the moon or around the surface of beyond the arguments missions whatever current goals for growing the deep space networks capabilities. I just in fact I just sort of Summarized one which which is it's broader than of course just Artemis An essential aspect is arduous but Of course having more antennas enables else not only more crewed missions with humans on board but more robotic missions to other destinations in the solar system One of the essential essential aspects is to try to increase the radio frequency at which commands are sent and data are received There's there's an fundamental relationship. Between how much data one can transmit and the frequency the radio frequency at which the commands are sent or the the data received and on on top of that things like cellphones and Five G. and and other such uses of radio waves are causing increasing facing congestion and in the radio spectrum. So we're the the deep space network And now send general with like missions to move to higher frequencies So can transmit and receive more data in the near term that's focused on radio wavelengths radio frequencies Looking a little bit farther ahead one. One of the goals is to transition to laser communications actually sending laser laser beams back and forth and again. This is all focused on the idea that as we go to higher frequency so Like eat lasers are higher frequencies than radio we can transmit more data. It's it's kind of equivalent to using fiber optics if you will without the fibers Across the solar system and that should enable even higher data rates and and in the near term in fact some of the thirty the existing thirty four meter antennas in the future what and some of the future ones to be constructed. They may very well become both with radio. Antennas and Optical Telescopes Essentially integrated optical radio with the idea that you can use them either for radio communications for existing spacecraft or maybe in the future laser or optical communications for for new spacecraft. So those those are the key technologies. uh-huh both moving to higher radio frequencies and that ultimately two laser communications is it a challenge maintaining operational network while also implementing these new technologies Sundays. Of course yes Truly in the case when one is retrofitting antennas so adding an optical or laser capability l'idee to an existing radio capability. It's very much like trying to Do an upgrade to a car or replace or Improve something on a car while it's being driven and so always has to keep in mind that there are existing spacecraft out there With technology allergy. You can't change the spacecraft of course so you have to be very careful not to do something that would disrupt a current spacecraft well enabling capability for new spacecraft craft and perhaps the ultimate example of that is our the voyager spacecraft the two voyager spacecraft they were launched in nineteen seventy seven so anything it does has to respect and and be backwards compatible with the kinds of things that Were being done in the late. Seventy and turning them into the far future of deep space exploration A. What unique challenges do you think? The networks of a hundred thousand years from must face that's a fascinating question and my my initial thought was predicting that far Out His incredibly challenging Of course I have the benefit that any predictions I make my won't be around to figure what if I'm right or not but I thought about this in the sense of maybe the best way to imagine what communications might be like in the distant future is to look to how communications were done in the distant past and if we think back say say two thousand years to the Roman Republic And I guess the year nineteen eighty or eighty nineteen was kind of it was at the end of the it was well. After the end of the Roman Republic in the beginning of the Roman Empire the Roman Republic and the Roman Empire did a very good job of building essentially high capacity roads between major cities and my expectation is that that act kind of architecture is likely to remain even into the far future so if one wants to If one wanted to transmit data data between Rome and Ravenna or Rome and Brindisi there were major roads. That ran along Italy or along the Italian Peninsula Tesla for transport of materials and of course communications. Today we've we know how to aren't as light or radio waves in a way that the Romans.

They're almost equidistant in longitude so each was about one hundred twenty degrees apart Which means that no matter where a spacecraft is in the solar system it can always see Out least one on. ESPN TANA for receiving commands from earth and then transmitting data. Back and what sort of missions does the network currently support indicated it supports Abel's missions everywhere across the solar system. And in fact if you if you simply do a web search on DS and now now there's a website that allows you to view in real time. What date are coming down or what commands are being sent up from various base crop up looking at speak and just to give you ample of the suite of of missions that is is enabled by the Sun in Madrid there is is Data be coming down from Soho which is a joint European NASA mission to study the Sun there are data coming down from Juno which is the spacecraft orbiting Jupiter at Goldstone Currently Mars is overhead at Goldstone so there are two antennas. Actually that are hi. There transmitting commands or receiving data from four different spacecraft for landers at Mars There's also a data coming down from Sean Ryan to. which is the Indian mission at the moon and Canberra Dare coming down currently from Voyager. Two which is actually actually spacecraft outside the solar system and It's actually coming down to seventy meters so it's an illustration of just how how much science the the network enables so. That's a lot of different missions. What sort of services do you offer them the DSM it provides three essential capabilities? They go by the names telemetry tracking and command often. Because it's NASA of course we need a acronym so often abbreviated to TNC PNC Telemetry is the Thing about which most people probably Have the most direct connection so you've ever seen a picture sure of planet. Undoubtedly that picture has come down through one or more antennas in the network and telemetry is that process in which the spacecraft transmits a signal or transmits data or an image from its Antenna from its system and then it's received by one or more. DSM Nintendo so the telemetry is when the spacecraft sends data down to the earth. DOWN TO US command. The C part is when scientist inches stir operators on the ground are sending commands up to a spacecraft to do something Take a picture. Gather some kind of data change its trajectory slightly lightly and then finally tracking the Middle T. is for trying to figure out where the spacecraft is on this guy or where the space craft is in space at and of course this is a particularly essential aspect with spacecraft is going from Earth to a destination we want to keep it on track as it were and the and ensure that it's actually going along the trajectory that will get it to its intended destination. And how is the network growing support the optimist missions to the Moon in the near your term One of the plans or actually the plan is for the network to continue to expand. As I said earlier. There are one. There is one seventy wendy meter at each complex and then three thirty four meter antennas each complex and the objective is to continue to build out thirty four meter. Antennas Antennas over the next five years so that each complex has four Thirty four meters in fact there are two thirty four meter. Antennas antennas currently under construction at Madrid In various states state construction and then there are there is one planned at Goldstone own for which construction will be starting relatively soon. They're already doing site surveys. Trying to figure out exactly where Next to the other three thirty four meters the fourth will go. And there's a plan for th one four Canberra Sort of middle of of next decade in the middle of the twenty twenties and we fat. Then there'll be numerous thirty four meters which will allow very high data rates down from The space craft at or on the surface purpose to the moon or around the surface of beyond the arguments missions whatever current goals for growing the deep space networks capabilities. I just in fact I just sort of Summarized one which which is it's broader than of course just Artemis An essential aspect is arduous but Of course having more antennas enables else not only more crewed missions with humans on board but more robotic missions to other nations in the solar system One of the essential essential aspects is to try to increase the radio frequency at which commander sent and data are received There's there's an fundamental relationship. Between how much data one can transmit and the frequency the radio frequency at which the commands are sent or the the data received and on on top of that things like cellphones and Five G. and and other such uses of radio waves are causing increasing facing congestion and in the radio spectrum. So we're the the deep space network And now send general with like missions to move to higher frequencies So can transmit and receive more data in the near term that's focused on radio wavelengths radio frequencies Looking a little bit farther ahead one. One of the goals is to transition to laser communications actually sending laser laser beams back and forth and again. This is all focused on the idea that as we go to higher frequency so Like eat lasers are higher frequencies than radio we can transmit more data. It's it's kind of equivalent to using fiber optics if you will without the fibers Across the solar system and that should enable even higher data rates and and in the near term in fact some of the thirty the existing thirty four meter antennas in the future what and some of the future ones to be constructed. They may very well become both with radio. Antennas and Optical Telescopes Essentially integrated optical radio with the idea that you can use them either for radio communications for existing spacecraft or maybe in the future laser or optical communications for for new spacecraft. So those those are the key technologies. uh-huh both moving to higher radio frequencies and that ultimately two laser communications is it a challenge maintaining operational network while also implementing these new technologies Sundays. Of course yes Truly in the case when one is retrofitting antennas so adding an optical or laser capability l'idee to an existing radio capability. It's very much like trying to Do an upgrade to a car or replace or Improve something on a car while it's being driven and so always has to keep in mind that there are existing spacecraft out there With technology allergy. You can't change the spacecraft of course so you have to be very careful not to do something that would disrupt a current spacecraft well enabling capability for new spacecraft craft and perhaps the ultimate example of that is our voyager spacecraft the two voyager spacecraft they were launched in nineteen seventy seven so anything it does has to respect and and be backwards compatible with the kinds of things that Were being done in the late. Seventy and turning them into the far future of deep space exploration A. What unique challenges do you think? The networks of a hundred thousand years from must face that's a fascinating question and my my initial thought was predicting that far Out His incredibly challenging Of course I have the benefit that any predictions I make my won't be around to figure what if I'm right or not but I thought about this in the sense of maybe the best way to imagine what communications might be like in the distant future is to look to how communications were done in the distant past and if we think back say say two thousand years to the Roman Republic And I guess the year nineteen eighty or eighty nineteen was kind of it was at the end of the it was well. After the end of the Roman Republic in the beginning of the Roman Empire the Roman Republic and the Roman Empire did a very good job of building essentially high capacity roads between major cities and my expectation is that that act kind of architecture is likely to remain even into the far future so if one wants to If one wanted to transmit data data between Rome and Ravenna or Rome and Brindisi there were major roads. That ran along Italy or along the Italian Peninsula Tesla for transport of materials and of course communications. Today we've we know how to aren't as light or radio waves in a way that the Romans.
