"Iridium Boss" Matt Desch states that by going with SpaceX they've saved "more than" $320 million on launch costs. They have one more launch before their NEXT constellation is complete.
Super advanced space age winch and pully technology looks a bit faster than removing the legs completely. Not to mention attaching them again later.
It looks like they added some sort of locking mechanism they can disengage near the base of the a-frame. I wonder how the locking mechanism in the telescoping pistons work, one way valve? The final stage of closing looks a bit dodgy, hope there's a failsafe to ensure they don't over tension the wires when it's nearly closed.
Earlier in the video it looks surprisingly labor intensive to disengage the roomba, I wonder why it can't just unlatch itself, or maybe just one of the arms was having issues?
Their webcasters should find a better way to pivot when the drone ship feed gets cut off. It happens every time but the reaction varies between apprehension and "maybe my puppy just died".
It looks like flight 3 for that particular booster is already planned, so that's neat.

Cross-posting from the [chat] thread!:
Llllllllllllllllladies and gentlemen, boys and girls, non-binary friends of all ages, TONIGHT we are going to see history (if you feel like staying up late! At 12:33am Pacific, 3:33am Eastern, 07:33 UTC, the Parker Solar Probe will be launching out of Space Launch Complex 33B onboard one of the most powerful rockets in the world, the Delta IV Heavy!
Weighing in at just 685 kg, the Parker Solar Probe is a compact little data gatherer! Planning to fly into the Sun's lower corona, the probe will get as close as 6.0 million km from the Sun, just 0.040 AU (1 AU = the distance from the Sun to us).
Because it is getting SO close to the Sun, the Parker Solar Probe needs to protect itself - in the form of 4.5 inch thick solar shield made of a reinforced carbon-carbon composite. Shit is intense, folks! Because the radio communication time to the probe will be 8+ minutes once it reaches its target orbit, the probe will have to defend itself from the Sun's intense light and radiation, positioning itself such that the solar shield is always facing the Sun. Because of this always-on self-defense action, the Parker Solar Probe is being described as "one of the most autonomous spacecraft ever".

And now we wait as PSP goes off on it's long journey.
Crew Dragon question I've been pondering: What happens if all of the touch-screens get smashed post circularization burn? Say in the unlikely event of a micro-meteoroid (or other unspecified debris) impact(s)?
Or if something comes loose inside the cabin with enough force to damage them?

If you ask someone from spaceX on twitter there is a decent chance they might tell you.
"I will write your name in the ruin of them. I will paint you across history in the color of their blood."
Also how well can you use a touch screen when everything is shaking? I find it really hard in a car to use an in dash touch screen without first putting another finger on the edge to stabilize my hand to the screen.
IIRC spacecraft crew are basically along for the ride as little more than ballast whenever the vessel is actually under accelleration. They probably wouldn't be touching controls during launch, at least (not least because reaching the screens would be difficult, much less touching them precisely).
For ordinary (nominal?) flight the touch screens are the backup for the backup. Primary control is the computers in the capsule, secondary is ground control and if those two fail the crew can take over. Shaking isn't a problem because if it's shaking they're either being launched or falling through the atmosphere, in either scenario there's nothing they can do save for pulling the big eject handle that is obscured by someone's arm in that picture. I wonder if one of those switches is a manual parachute deploy button...

I know about the LES handle. So presumably there's some ability to de-orbit manually? No screens, computers, or radios? (An unlikely FUBAR scenario, I know).
In less exciting news, there was a pretty grueling 8-hour E.V.A. by two cosmonauts on the 15th, where they launched handheld satellites into orbit among other tasks. The walk was captured by camera footage included GoPros (one of which was accidentally broken by a cosmonaut? Apparently the casing was damaged it failed shortly after they completed their duties).

There are manual controls (i.e. a shitload of physical buttons) situated below the touchscreens as backup. They are covered by a glass panel to prevent accidental operation.
I honestly wonder of a voice control system would be possible as a backup, TNG style.

Except for the soccer players, they've been training for that scenario for years.
I think I've missed something here, because I'm bewildered as to how it will be tactically useful in the future to ruin a sport with fantastically overdramatic fake injuries.

The hole was actually in a docked Soyuz orbital module (the part of the spacecraft that gets thrown away prior to reentry), near the hatch.
The application of kapton tape slowed the leak considerably, giving them 18 days to solve the issue.
The issue has since been resolved through the application of more permanent patching solutions.
Even at the initial depressurization rate, the crew were never in danger given the hole was in the hull of a visiting spacecraft, and not the ISS itself. Still, happy to see it get resolved quickly!
... That's ... that's gotta be a real pucker moment.
Couldn't have been too bad if they didn't even bother to wake up the crew over it.
It was slow enough that the stop gaps would have been at least enough to buy them weeks worth of time even if it did not prove to be more permanently patchable.

At least NASA is sticking to it's safety requirements these days and not rationalizing why they don't really need adhere to them.
Edit: Looks like Boeing's Starliner will be delayed 6 months
Bob and Doug will be the first to ride the dragon. They're all doing a Reddit AMA right now.

No.

That's the ball-shaped part, not the can-shaped part, of the Soyuz spacecraft.
Well, crisis averted.
Couldn't have been too bad if they didn't even bother to wake up the crew over it.
