    Ha. That was my first thought too. People speculating on FB think it means 0 exterior pressure but double internal pressure. So 0 psi external and 6-8 psi internal. Both Dragon, CST-1000, and the ISS are designed for normal 1 atmosphere at sea level.

    So the suit ended up looking like the leaked picture from over a year ago:

    Wouldn't double atmospheric pressure be more accurate? On the other hand, Elon knows more about Space than I ever will, so who knows.

    Waaalllll....until I'm comfortable Mr Musk won't again conflate atmospheric and vacuum pressures....I'm going to hold in abeyance my transit to Mars, I tell ya.

    We haven't got confirmation there's a HUD in the helmet either...

    It would be rather simpler to leave external pressure at 1 atmosphere, and inflate the suit to 3 atmospheres. So I imagine that's what they actually did.

    Does anyone else think that that is Elon inside, in the photo he tweeted?

    Sure hope they get the panel gaps right.

    Here are the minutes to a government meeting discussing, among other things, Commercial Crew progress. Some very interesting tidbits pertaining to the company there:

    Micro Meteoroid & Orbital Debris (MMOD) on Dragon capsule.
    COPV 2.0 and improved Merlin for Commercial Crew
    Other notes on Merlin Changes

    With excerpted details on these things here:
    Info regarding COPV 2.0, Improved Merlin in recent ASAP meeting minutes (pdf) • r/spacex

    You have to read between the lines but it seems that SpaceX is on track for their April unmanned launch and their August manned launch.

    Sadly, I think so. The focus on safety at NASA is huge. If something goes wrong and an astronaut is lost then the USA could blame Russia. Though, to be honest, Russia has done very well. They've launched about 50 of our astronauts with no losses. Money-wise we've spent a lot those launches.

    Russia is squeezing NASA for more than $3.3 billion — and there's little anyone can do about it

    $3.7 billion has been given to the Russians.

    Changing the subject off of Russia:
    Gwynne Shotwell mentioned at The Space Council meeting that Dragon can carry seven but NASA will only use 4 seats at maximum.

    Do you know if they (SpaceX) can sell the extra seats to the other countries that participate in ISS? Or does NASA have a right to all of those seats and can choose to use them, sell them or leave them empty?

    And a closely related question - does SpaceX have the option (once commercial crew is proven, up, and running), of doing their own private run to deliver astronauts etc.. to the ISS independent of NASA? Could SpaceX sell Russia a few seats to get Russian astronauts to the ISS? Heck - could SpaceX go throw up their own ISS2....

    H'mm...

    I would expect that NASA has final say on anything associated with a NASA launch. NASA refused a small orbital burn on CRS-1 to correct for the one Merlin failure to ever happen. That caused the loss of a secondary satellite payload Orbcomm OG2 due to an abnormally low orbital deployment. SpaceX asked to make the correction to save the satellite and NASA refused.

    Since their working relationship is now quite good with NASA, I expect that SpaceX could request use of the extra seats for someone but NASA could tell them no.

    Take note that another country could always buy a launch for themselves and use all seven seats. However, I don't think the ISS is equipped for a large crowd. It's probably unlikely that NASA will ever use more than two seats at a time.

    As for creating an orbital habitat, absolutely SpaceX could create their own or work with someone like Bigelow to do it. I fully expect to see such a thing happen if BFR/BFS proves to be the game changing rocket it seems to be.
