Are you ready for some REAL robots in space, /m/? I know some of you were around for the awesome Mars landing a while back, and the time has come again for another historic space mission.
In a little under 15 hours (GMT 0900, 4am EST, Nov 12), the Philae lander will detach from the Rosetta craft and approach comet 67P/Churyumov–Gerasimenko and attempt a landing, which should happen roughly 7 hours later (GMT 1600, or 11am EST).

>awesome Mars landing
I remember the first time I read how they were planning to put Curiosity down I thought: 'Holy crap. What idiot approved that plan?'. They sure proved me wrong. I hope this on goes well. Hopefully there's gonna be some amazing video coming in.
This is yet more unwarranted human intrustion into the natural environment. We should stop this pollution of our natural space with junk like this, which won't degrade until it is caught in a gravitational well and dragged into a world's atmosphere.
Yes. We've already fucked up our planet with things like the Pacific Garbage Patch, and our orbital space is dirty as shit. I fully expect a Kessler event within the next decade, when we will finally be stopped from expanding past this fragile world of ours to others until we solve our wasteful and polluting impulses.
The resources used for spaceflight and space exploration would be much better spent on Earth anyway. The entire NASA budget could've funded full public health care for every American, not just citizens but also the undocumented inhabitants of the nation and the unemployed and homeless. Or we could build new cities for them with that budget, providing jobs in construction and homes at the same time.
And this is why modern spaceflight is fucked. People come up with extraneous, unnecessary equipment because they need a purpose in the space program, costing billions more than it should. Just look at Mars Direct for a story of how Mars missions have continually been screwed over by departments trying to get a slice of big gov money.
Presumably they already have thrusters to get the craft back on path to the Earth, yes? So why do they need a dedicated counter-recoil thruster when they can land with harpoons and get back with a proper engine?
Go away Kojima. I had to hear this speech from Gates once already, I don't need to hear it again.
Pretty much every first world country besides Americaland has one. America is just ass-backwards because the citizens there could be convinced to commit suicide if they were told that living is the gubberrn'munt stealing muh freedoms.
That's pretty /m/.
You goofball, the counter-recoil thruster is there to help shove the lander into the comet as and after it touches the surface. It counters the thrust of the harpoons deploying. This is important because the comet has such a hilariously small gravitational field that you need just the right amount of speed (and thus force) to "stick" without bouncing right off, as well as luck in the landing zone being made of something solid and dig-able instead of powder.
Newton's third law of motion, nigga.
It's the same reason the Apollo 13 guys didn't dump their pee into space(and instead have them bagged up in bags) when they were waiting to get back home in the capsule after shit gone wrong.
Manual retrieval of space junk would be massively uneconomical. Most likely solution involves ground based high powered lasers.
What you're talking about is an argument against the launch of communications satellites and even regular resupplies to the ISS, which litter our orbit with debris from their rockets. No one gives a shit about a fridge-sized lander in the massive, empty void that is the rest of our solar system, especially when it's expected to ride a comet for the next forever and thus would be indistinguishable from any of its other debris for collision purposes.
And no one's going to stop launching communications satellites.
Investment in space exploration returns massive benefits to us. Things like LASIK, hydroponics, GPS (commonly thought to be entirely the military's doing), kidney dialysis, and some forms of water filtration systems all stem from research done on the NASA dime to solve space-based problems, to say nothing of what other agencies have helped in. NASA also developed EZVI, a clean-up solution to take care of dangerous chemicals resulting from their own launches, which has seen widespread adoption for all sorts of environmental shit unrelated to its original creation. From stuff like this and more, it's been said that every dollar invested in space exploration is returned to us as 1.7. That's pretty damn great, and it's fantastic that NASA and other space agencies can produce real, tangible improvements to our quality of life through pushing the boundaries of SCIENCE, not just improved "brown people murdering" techniques like military research arms.
People with an understanding of space, or who have been there, have a far greater appreciation for the fragility of our world than us. When you get out into orbit and see that tiny blue-green marble, with its lack of borders, or can see from year to year the changing colors of the planet and shrinking ice caps, and learn about all the incredibly deadly things out in the void that could wipe us out in a snap, you really begin to realize exactly how insignificantly tiny and precious the planet is.
>ESA livestream just had an interview with a scientist named Klim
Can we get any more /m/
Everyone in Japan is given health care, no matter what. It's part of why their taxes are kinda high.
You CAN buy into a private plan if you want, and that provides better coverage of course, but the public option is always there.
Why are you not on this stream, /m/?
There's NASA TV streaming their coverage too.
>It's happened but we won't find out for 28 minutes
They just said they'd have another update at 8PM (1900 UTC). There's nobody in the Ops center, so it's either a big deal or not a big deal. MC did just say they were all doing interviews...
Worst that could happen is the screw-feet fail and something knocks the lander off in the next five minutes. Or the harpoon propellant explodes and the lander is unusable, with some fragment flying out and hitting Rosetta proper. Those are both really unlikely though.
It looks like it might (and I stress _might_) have very slowly bounced off, rotated a bit, then landed again in almost the same place. Everything looks stable for now, and they're getting plenty of data.
That's how it is, even for successful missions. There are so many things that can go wrong that something eventually does, so you have to keep a brave face on while fixing the problem. If you're lucky, and it looks like they were in this case, it can either be solved or it's not bad enough to nix the whole mission.
And in either case, we know this is possible now. All they have to do is figure out what went wrong and make sure it doesn't happen again. Or at least do their best to make sure it doesn't happen again.
>Philae lands without its thruster working, harpoons hooking, or screws anchoring
>bounces off the landing zone and falls back down repeatedly
>winds up AN ENTIRE KILOMETER AWAY
>INSIDE A CAVE
This is bad from a battery charging standpoint because it means less sun from the panels, but the team is hoping that as the comet continues to move they'll get a better angle and the light conditions will improve somewhat on a non-short term basis.
God, it's so weird. It looks like the set of an old sci-fi movie.
It's surreal and really throwing me. Like, even Mars throws me since it looks like Arizona.
NOTE: I've never been to Arizona.
Feels bad man. Still, they have 64 hours of battery life remaining, so at least they'll be able to get some data thanks to that (and maybe catch a glimpse of anything hiding in that cave)
The primary mission was always planned to be completeable in the 64 hours of battery life. More would've been great (and I'm sure they had an idea of what to do with it), but Philae will still accomplish what it set out to.
one day we will be invaded by other species in space.
Time for bitch tears
The lander has completley 100% of its science objectives even after ending up in buttfuck rocky outcrop on its side.
And chances are it will still wake up next august with more sunlight. 1 billion euros well spent.
Sleep well little probe, you did good.
Japan was like, the FIRST big experiment in full on welfare state, all the other first world countries looked at how things went and adopted the useful policies without going too overboard to gimp their own economies.
Except America... who are so irrationally terrified of any policy even remotely approaching the socialist side of the spectrum that they'd instead of streamlining healthcare into an efficient system that works with two or three options, they'd rather leave objectively worse options open so that people can have muh freedom to make the wrong choice.
You done did good, kid.
>You will never go to the Lunar museum and see with your own eyes the Eagle, Armstrong's footprint and what's left of the flag in your lifetime
It's part of Shinto belief that hand-crafted and beloved tools will come to life after a century, once the electricity (which itself seen as a spirit) leaves them.
I'd like to think that our space probes out there will one day come back to us.
>our space probes out there will one day come back to us
Looking on the brighter side, If SpaceX can pull off what it proclaims to achieve, you may witness the birth of Humanity's efforts to colonize space beyond Earth's sphere of influence
>I just started lifting myself up a little and will now rotate to try and optimize the solar power!
>Also my rotation was successful (35 degrees). Looks like a whole new comet from this angle:)
>My #lifeonacomet has just begun @ESA_Rosetta. I'll tell you more about my new home, comet #67P soon… zzzzz
I-it's okay, /m/. It managed to rotate so its panels get some light. When the comet gets closer to the sun several months from now, there's a chance there'll be enough light to charge the batteries back up. Believe in Philae.
Anyone know how long until 67P/Churyumov–Gerasimenko reaches periapsis?
>Philae lands in a shadow and can't recharge its batteries.
What a shamefur dispray of engineering. You're supposed to plan that trajectory shit out. That's what math is for. At least it was able to fulfill the basic part of the mission so far and analyze some samples from the comet.
They did plan that trajectory shit out. They also landed in pretty much exactly the right spot. None of the anchoring mechanisms worked properly and Philae ended up elsewhere.
Not everything goes according to plan when literally no one has ever done anything like it before.
