Could we repair missions like JWST and Gaia? Polaris Dawn returns to Earth, did Earth once have rings? and a peanut-shaped asteroid just drifted past Earth.

oh godddd, please explain more about that gravitational microlensing to confirm exoplanets!!!! please! What do we need to get involved there!

Thanks Fraser for another great show and have a wonderful weekend. PEACE AND LOVE TO EVERYONE ❤❤.

Thanks for all the news, Fraser! 😊 Stay safe there with your family! 🖖😊

I've observed the Milky Way's glow in my suburban sky slowly fade away over the course of around a decade and a half as the artificial glow from city lights became brighter. It's still observable under very good conditions, but it's like a mere ghost. So unfortunate

Great presentation as ever, thanks. Well no doubt have a bigger better even more amazing telescope to upgrade on JWT by the end of its term

I wished that they launched space probe to Uranus and Neptune first before any other space mission because it will take more than 13 years to go to either. I don't want to be old when they finally made it into a reality

2 Mission, with two probes, with the same equipments. One to Uranus, One to Neptun.

We could get a long lasting second moon if an asteroid followed an orbit that came close enough at the right speed slightly outside the lunar orbit at perigee so that it was pulled around the moon and left the lunar gravity well inside the lunar orbit at a lower orbital velocity around the Earth than the orbital velocity of the Moon. It would then stay in that orbit for years until it matched the moon in its orbit so that the moon could poll it out again. Alternatively, we could "engineer" such orbits for metal rich asteroids that we could park in an orbit between Earth and the Moon while we use their materials to build large space stations in orbit.

They had the farsight to include a repair and refuelling possibility. To me this means they've learned that JWST just might be viable after its' shelf life like the amazing lifespans of the Voyager probes still sending back data and enabling software repairs to do so. Xlnt, we ain't dumb as rocks afterall.

This mission to Triton sounds pretty violent. If there is anyone living under the ice, won’t this look like a bombardment followed by an invasion? 🤔

Earth still has rings. they're called Starlink 😊

@thabzmad7265 2 часа назад

Those are not rings, they are Dyson spheres!

Repairing telescopes at L2? Heck we can't even agree whether we fix Hubble again. For that matter, we can't even fly perfectly fine and working moon rovers. 😅

@frjoethesecond 3 часа назад

The Free DSM project is interesting, but they need to produce and sell the hardware themselves for it to have enough reach. Having to buy the parts and assemble it is a major roadblock to casual space fans.

Manned repair mission to L2... even vaguely possible? We're considering Mars, and L2 is so much closer. On the other hand, that's still an awfully long time (30 days out, a couple of months on-site, 30 days back) without a convenient planet to aerobrake against or use for other gravitational shenanigans, meaning a significant propellant issue, as well as that pesky radiation. On the other other hand, a refueling mission for return could precede or meet the repair crew at L2. More helium, more propellant, replacement reaction wheels, patches for perforated light shields? New instruments? Granted that these missions weren't designed to be serviced, I would think that at least bolting on a module to enable station-keeping and attitude control should be relatively straightforward. Also maybe carry some smaller-in-size additional missions for L2 work. Sounds like a job for Starship! We could, y'know, practice on Hubble... and this could be practice for Mars, too, as an intermediate step that had real productivity beyond just practicing.

Fraser! I need your say on the private mission to Venus that is supposedly launching no sooner than the end of the year. Said mission being Rocket Lab’s Venus Probe.

Fraser, here in Brazil we have a saying that is more or less like this: "money doesn't bring happiness". But, well, after Polaris Dawn... I beg to disagree. 😬

I know this might seem petty... but I don't like Neptune as much when it's "true" colour was revealed. I want it to be deep blue again!

@911review 3 часа назад

So to delineate a name like "moon". Don't we need criteria? What does it mean to be a moon. ? Does it have to be a certain size, or, stay in orbit a certain amount of time?

@bmobert 4 часа назад

Question aboit starshot: how much energy would be released if one of these hit a planet around alpha cin? And how big of an local asteroid have to be, going at local interplanetary speeds, to be equivalent? Yes. I could calculate this on my own but then I would be the only one to know. Thank you.

@thabzmad7265 2 часа назад

Not going to be much. Someone simulated a grain of sand hitting the Earth at some 99,99 c and the effect was only comparable to some off the shelf fireworks,a bit more 9's 9.9999 and they got a few tons of dynamite_.

my god, we could send those swarms to our own solar system instead of waiting for 12312321 years NASA project :(
