    News Delta II towers at Cape Canaveral toppled

    No editing, you can see the plant in the foreground moving with the audible booms. The loudest audible boom is a while later than the big explosion on the left tower.

    News ISRO Successfully Tested Crew Escape System (Technology Demo)

    The parachutes were cut before the capsule splashed down. I don't think astronauts would have survived. Of course testing is done to find problems, but this one is so severe that they need to check their design procedures.

    Launch News SUCCESS: SpaceX F9 SES 16/GovSat-1 (Wednesday, Jan. 31, at 4:25 p.m. EST/21:25 UTC)

    This booster doesn't need an ASDS: Going to be hard to tow this to port with any speed with those big landing legs sticking out.

    Launch News Ariane 5 (VA241) : SES-14 (with NASA GOLD payload) & Al Yah-3 : Jan. 25, 2018

    The Ariane 5 did launch at the wrong azimuth. That is why they lost telemetry (because the tracking stations were pointed in the wrong direction) and why the inclination of the orbit is wrong. See this picture from a map a few minutes into the flight, the x denoting the actual position of the...

    Launch News Ariane 5 (VA241) : SES-14 (with NASA GOLD payload) & Al Yah-3 : Jan. 25, 2018

    Well, I am not sure. If the satellites would have been in the correct orbit, I'd think the statement by Arianespace would have mentioned that, so I am assuming the sats are not in the correct orbit. The question then is by how much the intended orbit was missed and if the sats can compensate.

    Launch News Ariane 5 (VA241) : SES-14 (with NASA GOLD payload) & Al Yah-3 : Jan. 25, 2018

    Maybe not all is lost: "The SES 14 and Al Yah 3 satellites are in orbit after tonight's launch, sources tell Spaceflight Now." They speculate that SES 14 could reach its intended orbit with the benefit of its electric thruster. ---------- Post added at 02:09 AM ---------- Previous post was at...

    Why did the trunk have fins? More solar array space?

    News Here be Dragons: SpaceX reveals manned Dragon design

    I bet it is just like the Dragon cargo, but with seats and LAS thrusters. Pretty boring, in other words. :)

    News Here be Dragons: SpaceX reveals manned Dragon design

    Bit strange to announce a live event and then be at least 15 minutes late. :hmm: Dragon behind curtain: https://twitter.com/jeff_foust/status/472197849585688576/photo/1

    Launch News SpaceX Falcon 9 F3 COTS2+ Updates

    The "crack" is explained under the photo in the link C3PO provided: "Visible are the diagonal channels that held parachute lines during flight, under a layer of thermal protection material." Edit: Ninja'd by n112vu :)

    some girl got head trauma at sxm

    http://g.co/maps/9nbfj Looks like the plane used the area with the yellow chevrons. In other videos of the same place, the jet blast seems a lot less severe.

    Launch News Blue Origin Suborbital Test [FAILURE]

    From what I read, this thing is meant to do suborbital hops. We can't say what the problem was, as these guys are pretty secretive. It will most likely not be an obvious problem, as they are rumored to have a pretty decent team.

    News French plane lost over Atlantic

    If we assume that the plane has a vertical speed of 55 m/s and that the plane will stop in 2 meters of water (just a wild guess) and that the deceleration is constant (assumption), it will stop in 2/(55/2) = 73 ms. The deceleration will then be 55/0.073 = 753 m/s^2 and the vertical impact would...

    News Japan Earthquake, Tsunami, & Nuclear Disaster

    Hmm, reactor 4 now on fire and a measurement of 0.400 Sv/h on the site. That doesn't sound good at all.

    If they are hit by lightning directly while being on the tower, they are toast. If the lightning hits the tower, they would be OK.

    OHM Proton Launch Vehicle v.2.2

    I have a small issue with the new update: If I want to return to the Orbiter Launchpad with ctrl-q, I get a window with a picture of the shuttle and with the message: "Please wait while Orbiter is closing down the simulation session..." which hangs at about 80% of the progress bar. This happens...
