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!!
Your call to interview up-and-coming astronomers, this was the best 45 seconds on any show you did, ever. 90% of interviewees are interviewed frequently! This offer you make changes that, and this is Good 👍❤️
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.“
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.
@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.
BTW, your interviews and the subjects and scientists you select are excellent. I greatly appreciate the knowledge, understanding and insight I have gained through watching them.
I continually learn _sooo_ much from this channel. He puts in full time hours on these productions and it's abundantly obvious. In my opinion it's one of the best space channels on the entire internet. Love it!
How about an interview with a custodian at one of the major labs like LHC? I think it would be very cool to see about what kinds of mundane things are needed to keep those things running.
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.
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?
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.
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.
@@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.
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. 👍🏼
Cleaning Regolith from space suits, one method would be to use ultrasound projected from inside the suit and using an anti static charge ! The moon has a static charge that's why the dust particles of Regolith hover above the surface, as for Mars its Regolith is mostly Iron being magnetic it could be removed with a magnet !.
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.
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.
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.
Regarding Ingenuity. Good story on your drone crash theory NASA. Everyone already knows that the Sandstorm elementals got fed-up with the buzzy flying thing hovering over their home and snatched it out of the air. 🙄
15:00 Could the twin galaxy be a mirror image of the milky way? Is it possible that we observe this galaxy along the curvature of space, and see the childhood of our galaxy?
When JWST reaches its end of life, it will join Gaia in the center of the Lagrange point. How much room is there? This is a limited and valuable region. Shouldn't it be part of the plan to clean up after you are done?
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.
For an advanced Martian drone to rely on vision alone is a bit frivolous. It should have one or preferably two more alternative methods of navigation, from radar to echolocation🤦♂
I've got a case of getting old. However, that's all due to lighting. You can see the beam of light across the room, coming from sunlight. Sleep is normal for my current obsession on a new video game. :-)
Hi Frasier, are you a person who allows your personal feelings for an individual to impact your opinion of an organization said person is associated with? I would like to believe any person, with influence on a group, would set aside personal feelings, positive or negative of associated individuals of an organization, and evaluate the organization on its performance alone. Thanks.
I want a Super Gaia! Two space near/mid infrared parallax telescopes orbiting at Jupiter's L4 and L5. That would roughly give 5 AU of parallax distance. Put a tight beam com laser on it, and an Epstein drive. Starship, New Glen, and SLS would take way too long. 😂
For all the Americans giggling for hours after the planet Uranus is mentioned, Gaia was his wife, and had him castrated, she got her sons, the titans to do the deed, something that learned Chronos an important lesson

Thanks for all the news, Fraser! 😊
Stay safe there with your family! 🖖😊
If Ingenuity had crashed into a tree, colonizing mars would be a lot easier.
Haha! No doubt. Haha...
Some day there will be telephone poles on Mars with sneakers hanging from the wires.
@@javaman4584 *Space sneakers. 😆
Oh not GAIA😢 the astrometric bread and butter Mission❤
I find it surprising that building another GAIA satellite is less expensive than designing it to be refueled.
A strap-on for Gaia...
How about an interview with a custodian at one of the major labs like LHC? I think it would be very cool to see about what kinds of mundane things are needed to keep those things running.
If Ingenuity managed to crash into a Martian tree, it would have been the first to discover extra-terrestrial life.
That'd be one tough tree. 😆
One of my high school classmates worked on the helicopter.
I'm sure he's devastated.
He should not be devastated, he should be incredibly proud. That little chopper astronomically over-performed.

So much GREAT information by Mr. Cain. Thank you 👍🙂✨
19:28 I don't get the point of using nitrogen. You have to do it in a pressure chamber anyway and if you're there why not just use water?
When Gaia first launched, they said it would detect thousands of exoplanets. How many exoplanets has Gaia actually detected?
15:36 🦄

Hopefully Dragon Fly will not suffer the same fate as Ingenuity as it is flying over a featureless methane lake.
My iPhone has a camera that can sense depth. And Xbox Kinect is a couple decades old. I’m surprised they don’t have that capability on Ingenuity.
What was Wolowitz doing on Jan 18 2024?
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.
Cheaper to build a new Gia and launch it than to rescue Gia.
15:00 Could the twin galaxy be a mirror image of the milky way? Is it possible that we observe this galaxy along the curvature of space, and see the childhood of our galaxy?
Sabine Hossenfelder just published a video yesterday about super flares of the sun.
My guys at U of I making us flatlanders look good! Way to go.
Wha!? No! What a bummer...
Flares can also harm Earth-Mars spaceships.
Perhaps the drone sightings in New Jersey are Ingenuity's ghost
Most lenses seperate colors to some extent. I am guessing a grivitational lense does not do that?
That would be Twilight Sparkle.🦄

thanks Fraser salute from Newmarket Ontario do you think Canada will ever get its own Space launch area anywhere in the country?
Has Gaia ever snapped a pic of JWST or Euclid either accidentally or on purpose?
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.
This rescue would be the fraction of the cost of a new GAIA plus improve distance measurements 10 times.
Have you ever interviewed "Hello wonderful person."?
Yup, I did a fun episode with him and Joe Scott last year
For an advanced Martian drone to rely on vision alone is a bit frivolous. It should have one or preferably two more alternative methods of navigation, from radar to echolocation🤦♂
You should interview Dr Becky youtuber a also PhD in astrophysics
We've chatted a few times in the past. :-)
should we send some future astronaut to either fix ingenuity or just pick it upto p send back to some space museim.
Do you get enough sleep, Fraser?
Your eyebags got worse :(

Crash into a Tree 🎄? on Mars. So You Watch My Little Pony ! ! ! 🐎
The Voyagers had more redundancies built-in than Ingenuity.
Flying Martian Rovers
Algorithm! I’m actually going to watch this later when I can give it my full attention but for now, algorithm!
Äh.. "Larensche" Punkt? "Einfallsteichtum" "Schurkenplaneten"?
Clearly, you should take to flying your drones on Mars. :)
You say you love Gaia, but we all know that your true loves are Nancy Grace Roman and Vera C. Rubin.
We're all going to die😮
My theory that it crashed while checking out some daisies
I still think it was a tree. Look closer.😅
