    I couldn't find a clear reference to whether that was with a single scope or using all 4 in interferometry mode?

    If its a single scope then this means super amazing things for the 30m Telescope & ELT :-D (probably also even if it was in interferometry mode)
    Very excited to see what comes out when we have those 2 + James Webb Space Telescope all running :yes:

    That! Even though I treasure every single "little" mission to Mars, as I previously shared here I think these multiple present and near future missions are already redundant! I think all parties capable of putting up a mission to Mars (mainly NASA and European agencies) maybe should unite and think about a really big mission to Mars.

    Neither NASA or ESA are capable of a manned mission to Mars in the next decade, even if they teamed up. SLS is too expensive. ESA don't even have a big enough rocket on the drawing board.

    The only manned ticket to Mars before the 2030's will be if SpaceX manage to pull off the BFR.

    That's what I was thinking. So, they'd better prepare a mission for when that day arrives... but they're not doing it.

    You know that mission preparation is long, from their proposal to every stage of approval, budget, testing, etc. They could be doing it now, but they are not, so when the time we have a powerful enough/suitable rocket to go to Mars arrives, they won't have a mission prepared and ready to be deployed.

    Or maybe when they see that BFR (or other techs that may arise) is real and capable to do what SpaceX says it will do, they will hurry, prioritise and think of/do something quicker than what's normal.

    Congress will be directing NASA's human flight funds to SLS/Orion/LOPG for the foreseeable future.

    I'd have thought the first manned Mars BFS flight would be far too risky for NASA. They have to build a propellant plant and mine 100's tonnes of ice just to come home again. And spend longer out of Earth's gravity/rad protection than anyone in history.

    And that's why they should be planning now all those things, not just how to get there, instead of just waiting and only putting an effort on sending more rovers/satellites until the moment when a proper transport to get there is ready.

    How timely, bearing in mind the last posts in this thread! :-D

    Ok, I just keep eating crow...

    It seems that they are indeed looking into all the things I mentioned a few days ago, when I was complaining about the lack of research regarding not just how to get to Mars, but also on the things we need to know and do once we get there (shelter, protocols, etc.).

    We don't know that for sure, but it makes sense and it could be it.

    It's the first time I hear about these "light echoes". Amazing.

    Some SpaceX updates:

    I would like to hear some news on the progress with the BFR, though.

    There should be a BFR update within a month or so.

    I think it's probably a good idea to be secretive around their Mars conference. There's no way to brainstorm bad ideas in public with the spotlight that's on SX/Musk.

    Yeah, I think that's a good thing, too. I'm also happy that this project is active and being further researched and discussed. :)
