Now I have that "Jews In Space" skit from "History Of The World: Part I" in my head:
Israel plans to land unmanned spacecraft on moon in February
Israel plans to land unmanned spacecraft on moon in February
Point of order, today is the 3rd launch of block 5: https://en.wikipedia.org/wiki/Falcon_9_Full_Thrust#Block_5SpaceX is attempting to 1) fly and land its first block five engine and 2) catch the fairings.
1) is important because in order to have human-rated spacecraft you have to freeze all changes to the spacecraft and fly it, unchanged, without critical errors, for some number of times (I've heard 9) before it becomes human-rated. SpaceX changes Falcon 9 stage one frequently, sometimes minor changes for each flight, so they haven't been able to attain human rating for it even though they've flown the last 38 missions without launch failure. "Block 5" is the name they've given this specific iteration of design and they've locked it down from further changes.
And from Wired:The maiden flight launched the satellite Bangabandhu-1 on May 11, 2018.
...snip...
NASA requires seven flights before the vehicle can be certified for human spaceflight.
Above I also quoted the part about 7 flights necessary for human flight.Just three days after delivering its heaviest payload to space, the company will launch another upgraded Falcon 9—this time from its California launch site. The flight, scheduled to lift off at 7:39 am ET on Wednesday
Wind and weather may have been the big reason for the failure. The SpaceX spokesman said these were the worst conditions yet for a drone ship recovery.Wind and weather more strongly affect parachute craft than powered craft. They did increase the area of the net on the ship by 4 times for this attempt, however, it was a failure.
What little light there was from the rocket booster as it landed showed whitecaps on the waves, so not only was it in the dark, but it must have been very rough seas.Wind and weather may have been the big reason for the failure.

Neat video.Fly safe...
I'd like to say "something something russian build quality" but I mean, it's not like NASA hasn't had it's own issues with catastrophic failures whose roots were in management culture.Something something hurry up with our own launch vehicles SOMETHING.
Any failure from Soyuz would look bad on the Russians though, and Putin wouldn't stand for that unless he authorized the shittiness, and there's no benefit to them here. And there's Cosmonauts up there as well (I assume, I think there always are?), so I'm more willing to believe "shitty contractor" on this one rather than deliberate malice until more evidence comes forward.I feel like at any other time I would've just written this off as "of course it was a manufacturing screw-up by the contractor and they did a crummy job of patching it." These days, though...
Yes, myself as well.Any failure from Soyuz would look bad on the Russians though, and Putin wouldn't stand for that unless he authorized the shittiness, and there's no benefit to them here.

Two questions on this one:Less than 10 hours later, the probe set yet another record. Attaining and then surpassing a speed of 246,960 kilometers per hour (153,454 miles per hour), the Parker probe became the fastest-ever human-built object relative to the Sun.
Velocity is always recorded relative to "something". Most of the time that's the Earth, but for something so far away that stops making sense so they need to record against something else. The article specifying "relative to the Sun" is I think just making clear how they were measuring it.Two questions on this one:
- Is there a "reasonable" reference frame we have that would change the answer versus "relative to the sun"? I'm thinking maybe relative to the center of the galaxy (or some other much further out point) if in that moment the probe was going against the spin of the galaxy it's slower? Whereas once it goes to the other side of our sun, it'll be going "with" the galactic spin, and thus faster? That makes sense to me, I just wondered what others might think
- I think most of us would consider a bullet fired from a gun a human-build object that has speed imparted to it. So should particles in a particle accelerator also qualify? We by many definitions "manufacture" those particles, and then accelerate them. By that idea, isn't the fastest "human-built object" then something short-lived in the LHC?
By this logic, I could break (equal, really) the record for fastest “manufactured” object just by turning on a flashlight.should particles in a particle accelerator also qualify?
