From “The Gaia Successor in 2021“ (Erik Høg 2021) on arxiv: “ESA has now ranked the development of this mission so high that a launch about 2045 is quite probable.“

[@bluesteel8376]

so only 21 years? lol

[@kamilZ2]

This is twice longer then GAIA lifetime, which is limited by fuel, cosmic radiation damage of silicon CCD, gyroscopes , micrometeorites, etc. I wish they manufactured a few GAIAs and launch one every few years to benefit from economy of scale.

[@scottdorfler2551]

​@kamilZ2 I would love to see Gaia 2. Two space parallax telescopes at Jupiter's L4 and L5. Roughly 5 AU of parallax distance. And with two telescopes, you don't have to wait 6 months, it's instant. This was tested with New Horizons and an Earth telescope a few years ago, after "Ultima Thule," the space snowman. If I remember correctly, it was tested on Alpha Centaury.

[@Top_Weeb]

The Europeans really do not fund their space program well at all.

[@mhult5873]

​@@kamilZ2 This is something I been hoping would be done for decades, e.g. also for Cassini, New Horizon, JWST, Hubble etc etc. I can't for the world understand why this is not done. All the construction and development are done after the first unit! Br

In a very early episode of Red Dwarf, Rimmer is trying (again) to pass his astro-navigation exams, to become an officer. The question he's working on is "What does the red spectrum tell us about Quasars?" As you might expect, he begins his answer the same way that a kid would begin a book report, for a book they didn't bother reading. When he's finished waffling, a look of confusion comes over him as he asks aloud "What the hell is a Quasar???" When I first saw that episode, way back in the early 90s, it prompted me to try to answer Rimmer's question. I wanted to know what the hell a Quasar was. Unfortunately, I had no reliable method of discovering answers to such questions back then, so that quandary stayed with me for at least ten years, possibly longer! Gods damn it!!! Now I wanna go and rewatch all 12 seasons and 2 movies of Red Dwarf!!

My husband spent the first half of his career studying trans-iron high energy cosmic rays. He leaned towards the super bubble theory, but I remember how giddy he was, as we sat in the NASA colloquium in 2017(?) for the multi-messenger observation of a binary neutron star merger. It was like he was suddenly seeing new possibilities for the science he loved so much. When he gets up tomorrow, I'll make sure he knows about new paper about neutron star merger flares as a trans iron cosmic ray origination. He's in aerospace now, but you never forget your first love. Thank you.

I find it surprising that building another GAIA satellite is less expensive than designing it to be refueled.

[@TheAdeybob]

A strap-on for Gaia...

[@steveg1961]

Satellites like Gaia should be made in such a way that a servicing robot with supplies could be launched to resupply satellites. I'm actually surprised this isn't already being done.

[@Tirani2]

There are companies working on developing and implementing the ability to refuel a space craft, they just have to be accepted by the agencies.

[@lethargogpeterson4083]

There will still be a lot of science done with Gaia data, and I think that includes Gaia data that has been collected but hasn't been fully analysed or calibrated yet, so science with the longest most precise measurements should still be coming, which is cool.

[@Flowmystic]

Fraser and team are the heroes we need.

[@mtritt1296]

Cheaper to build a new Gia and launch it than to rescue Gia.

[@blacksmith67]

Which would be better: fly a mission to Lagrange Point 2 to catch and attach to Gaia or to send up a new version of Gaia with over a decade’s worth of technology improvements?

[@nomdeguerre7265]

New GAIA with IR capability and, perhaps, greater resolution. This should be a collaborative mission between NASA, the ESA and the Chinese Space agency. I know that sounds radical....but it's really not..... ESA can run the project and the USA and China can contribute. It might be based on the mission model of MAUVE.

Too bad we can't send resupply-drones out to Perseverance. Maybe one big drone carrying many more 'standard sized ones' like before, or with 'standard drones as its motors' and the main ship being tons of battery and solar panels and maybe a tiny RTG for heat to keep the battery from freezing or whatever. It just heads in the direction that NASA sends it updates for every now and then so it can try to get to some area near the rover's path, and aside from that just 'fly wnw and don't run into anything on the way' to get to that general area. Yeah yeah yeah, I know there's more reasons than JUST that why it's unlikely, but I'd love if it could be done.

[@GadZookz]

Maybe Jared Isaacman will volunteer to go fix it in a modified Dragon capture with a Mars class service module. He could fix Hubble on the way back. 👍🏼

[@robertunderwood1011]

OK, you asked for experts in relevant fields. So let’s discuss the production of food and space Making protein 16:00 from methane and ammonia Also, making protein from carbon dioxide and hydrogen And incidentally Sugars can be derived without need for plants or photosynthesis - see Tobias ERB And the Chinese have developed a synthesis of starch again without needing photosynthesis These processes are much faster than what nature can do An overview of protein production using methanogens and Cyanobacteria bacteria Is published by a group called ALLFED in a paper by Juan Martinez.

[@dbireland2003]

Another very informative show. What are your thoughts on the Polaris delay? I think they need to develop a mars tug that could bring 4 star ships at a time. Then they could rotate them all together and create artificial gravity to reduce space sickness. What do you think ? Slowly adjust to mars gravity on the way there and earth gravity on the way back.

[@dbireland2003]

I’m just a licensed machinist with 14 years as a prototyper for JDSU and learned how to work with engineering to make impossible manufacturable. Really not that smart but still play around.

I would think if that could work keeping it at earth gravity the way there would be best. But on the way back yeah start low and build back.

[@dbireland2003]

@@Jameson1776 The reason I thought it would be good to wind down slowly to mars gravity on the was to allow the bodies motor skills to adapt. I think they need space tug maybe could be nuclear powered and save all that valuable fuel on the starships. But you might be right. Maybe we need a few runs to figure it out. To see what is best.

If Ingenuity crashed into a tree, that would be something. The search for life off earth would be over. Then we could focus on finding intelligent life in the universe.

[@denim_ak]

Question for the Q&A show, what was the reason the mars copter didn’t have lidar sensors to sense the distance to the ground? I imagine it’s just it was designed before drone technology advanced in the last 15 years but maybe there’s a more interesting answer. Lidar seems like a no brainer nowadays, if my phone can have it so should nasa.

ingenuity crashing into a tree would have been the most staggering scientific discovery of the century.

It must have been their hope. Either you never crash your drone or you discover trees on Mars. Those are the only two possible outcomes.

As you mentioned not all such events would be pointed directly at earth, but it does make me wonder how big of a cone solar flares make? Does the area vary by intensity? And what’s let’s say that we can’t a solar flare near the edge as opposed to directly aimed at us, how much does the intensity drop off the further you get from the center?

[@AndreasPeters-r3e]

Question for Q/A: Why does running out of fuel has to mean the end for mission, e.g. Gaia? I would understand it, if it fell into the atmosphere, but that is not the case. It just drifts away uncontrolled. I would assume that we can get data out of it for as long as we can keep contact (radio or laser). We were receiving data from Voyager for decades and it is so far out. I would assume the same should be the case for Gaia. Is it a abandwidth issue? Or is fuel also needed for orienting it? I assume that is mostly or completely done by spinning wheels.

[@hive_indicator318]

Voyager has an RTG

[@nomdeguerre7265]

Gaia's mission depends completely on precise aiming. It can't do that without propellant.

[@camsy83]

Also 'drifting away' may risk a collision with other observatories at the Lagrange point, such as JWST

The common sense restoration of Gaia is: 1… use starship to get a rescue ship into low earth orbit. (Low cost per pound to LEO) 2… the unmanned rescue ship locks onto GAIA and provides attitude control & thruster location control 3… the low acceleration rescue ship also propels GAIA to a much larger orbit around the Sun including gravity assists from Mars or Jupiter. This larger baseline will increase GAIA parallax distance measurements by an order of magnitude. 4… the rescue ship also provides upgraded antenna communication link to compensate for much longer transmission distances. 5… the rescue ship also provides much larger solar electric panels to compensate for weaker solar radiant energy per square meter.

[@douginorlando6260]

This rescue would be the fraction of the cost of a new GAIA plus improve distance measurements 10 times.
