  1. I'm going to shed tears over an overacheiving camera on wheels tonight, and I will not apologise for that. This rover has been around for two thirds of my life, and with the demise of Opportunity, all of the probes that inspired my love of astronomy (MER, Cassini, Kepler, and Dawn) are now dead. We will continue to explore space, and I will get to see Opportunity displayed in a museum on Mars, even if I don't get to return.

    Definatly, I've flown on that route before. The question is, do you value money or irreplaceable memories more?

    Arianespace launch thread

    It looks like it might be. Falcon 9 had its launch price reduced to 50 million recently, for 13 tons to LEO (for droneship recovery). Ariane 6 goes for 90 million, for 21 tons.
  4. Just to point something out here. Musk has repeatedly said that he's aiming for airliner levels of safety with BFR. Now, this is a hard thing to do, but if he can demonstrate that he has such a reliable vehicle, do we really need an escape system? If it does, then go to Boeing and Airbus and start pestering them for escape pods on all commercial airliners, because you obviously think that the risks are too high in todays aircraft. And no, we don't need to wait for several crashes of the BFR system to confirm that safety level. Planes have individual parts fail fairly commonly (given how many currently fly) and we can calculate from that how often a certain failure cascade will occur that results a loss-of-hull accident. The same logic can be applied to BFR when it starts flying. Starting unmanned is entirely fair and I completely agree, but I don't think that we should wait very long before we start manned flights.
  5. I'm fairly certain that it's an LED array, partly because I vaguely recall hearing about that, but mostly because if it isn't, then thus experiment wouldn't likely last a lunar night. 2 weeks without light is very tough on any plant.

    But why would they do that? Stainless is more than capable of containing LOX and LPG, why add mass to the rocket with seperate fuel tanks?
  7. I suppose that the main reason I'm wanting a fourth catagory for rocks is that the very first thing I've been told to do with a rock, throughout college and university, is to determine if a rock is sedimentary, metamorphic, or igneous, saying none of the above was never an option. Actually thinking about it, though, there is no reason that that is not a valid answer!

    Science, medicine, and quackery

    I've heard of 'leaky gut syndrome' before, but it was pure quackery. The person was trying to claim that gluten can cause autism (amongst other things) by opening pores in the gut lining, allowing undigested food into the bloodstream... Yeah, it's probably BS. Just to be clear, that is sort of, but not really, what gluten does, but there is no evidence that it actually affects gluten tolerant humans (surprisingly, most of us have evolved to eat our staple food). But on a more serious note, as someone who is on the autism spectrum, I've had mild gut issues for a long time, and as far as I can tell, altering my diet was about as effective as consulting my horoscope. Reducing stress did help, but diets didn't.
  9. True, but the question @kerbiloidraised is still a very valid one. At what size do we start using the sed/ig/meta system, rather than spectra? Spectra also aren't massively useful for hand samples.
  10. AFAIK, there is no term for the material on asteroids like Ryugu, which is a significant oversight, IMHO. I'd introduce a new term, something like "Primordial", to demonstrate that the material has not been altered by geological processes in any way.

    And at least this isn't Elon time, it's *gets into a needless political rant*. But seriously, it makes me sad thinking of all the media outlets screaming that SpaceX has delayed again, when it has absolutely nothing to do with them.
  12. At midday on the Moon, temperatures can easily top 140C, and it lasts something like 60 hours. There's no atmosphere there, so rejecting heat is a serious issue.

    Top 3 Rocket Launches/Missions of 2018

    IIRC, Es'hail 2 was the payload for B1050, the Falcon 9 that underwent aquabraking at Kennedy.

    Top 3 Rocket Launches/Missions of 2018

    Falcon Heavy/Elons ego Tesla Delta 2/Icesat 2 Falcon 9/CRS-16 And while its not a "favourite" launch, honourable mention goes to: Soyuz FG/Soyuz MS10 One made my jump for joy, one made me shed bittersweet tears (I've always loved the Delta 2 for its history and versatility), one made me laugh at an incredibly Kerbal launch in all respects, and one had me at the edge of my chair, hoping that we hadn't just witnessed the end of two heros. So, 2019, what have you got in store for us?

    How will we terraform Titan?

    Just to point out, there are exactly three places in the solar system that you can find free nitrogen: Earth Venus Titan If you're going to build habitats for people, or terraform planets, you need that nitrogen. We obviously don't want to take nitrogen from earth, so Titan would be exporting nitrogen to the entire outer solar system. The methane is nice for plastics, but not the most valuable resource there.
