    News Changes to the SpaceX BFR rocket.

    They basically get external imagery of Starship after ascent, get to test the deployment systems, and get to test v3 Starlink systems in space. That's pretty good payback for disposable satellites.

    Updates Blue Origin announces the New Glenn Orbital Launch Vehicle

    At least if they nuke the pad again they won't be blowing up another pricey transporter erector. Again, any information on the cause of the explosion? Progress on the pad is great, but having a non-exploding rocket to put on it would be nice too.

    Atmospheric Winds implementation

    Again, what exactly is the problem with the model? What are your expectations for the atmospheric wind model? Nobody can fix the issue until it is clearly identified.

    What exactly is wrong with the wind implementation?

    The quest for proper time

    I'm not fully understanding what you are working on, but my experience with computational modeling and numerical simulation causes me to suggest that you change the size of the time steps and repeat the calculation and see if that has an impact on that drift and your other results. Numerical...

    Updates Blue Origin announces the New Glenn Orbital Launch Vehicle

    Has anyone seen anything with regard to what caused the explosion? It's been a couple weeks and I haven't seen anything yet.

    Updates Blue Origin announces the New Glenn Orbital Launch Vehicle

    TLE and the launch deck are trashed. One lightning tower down. The launch tower has damaged strut members at its base. The doors on the far side of the horizontal integration facility are damaged, so the doors on the pad side and probably quite a lot of stuff in the HIF are damaged. Visible tank...

    Agreed. Hence why I said "yet". It's not even a NASA thing. Vladimir Komarov died because Soyuz 1 had to be launched on the Politburo's schedule, not when the engineering punch list was finished. Any national space agency has these political pressures.

    Here's some imagery of LC36 from this morning: Looks like a multi-kiloton explosion happened, which it was. One lightning protection tower is down, transporter erector is wrecked. The tower and deluge tank and other lightning protection towers and civil structures all took a similar blast to...

    Artemis hasn't killed 14 astronauts (yet). Careful what you wish for.

    With the explosion of New Glenn yesterday (and damage to LC36 and destruction of the transporter erector), that means the Blue Moon lander may not fly for a long while yet. If the BE-4s are implicated in the explosion, that might affect ULAs Vulcan. Starship as HLS is insanity, and Blue Moon...

    Updates Blue Origin announces the New Glenn Orbital Launch Vehicle

    It looks like the second stage exploded at nearly the same time, not simply toppling over after the first stage failure. Whatever failed in the first stage was uncontained and took out the second stage too. Yikes. Is FTS enabled on these static fires? It sure does look like both stages...

    Looks like insanity won over engineering, again. For some value of "reliable". They rather need a human rated lander that actually works and doesn't kill anybody by then. Maybe, but good luck with that. Good thing they are pushing for NASA budget cuts. Otherwise they might have money to do...

    News Changes to the SpaceX BFR rocket.

    Just catching up with the replay. The video is just amazing, start to finish. I didn't see anything about them attempting to soft land the booster stage in the water - did they actually get a reentry burn or did the booster just freefall like a bomb from engine shutdown after staging? And...
