It's join the dots time . . . Time to play “No Time for Caution” Do the computers have wise-cracking personas to salve? Like, "hey guys, are you sure you don't want ISS rotation input to make things more exciting!" Who turned the lights out? They have the likes of Buzz to thank for doing the groundwork for what they're attempting right now. Someone took the displays from 2001 to heart. It kinda looks familiar. The previous automated docking is old hat. If anything, this underlines how putting a human in the loop makes all the difference. That terra flash caught me out. The SpaceX docking sim makes it clear that continual thrusting is required to prevent off-centre creep occurring. This phenomenon is constant. Is that because the station and the capsule are separate entities of different size/mass being perturbed along the way? They're not effectively a single object until hard-docked. Left to its own devices wouldn't the ISS twist and turn according to incidental triangulation (torque) forces between earth, moon, Sun and man-made objects, not forgetting hot spots emanating from the Celestial Sphere itself? How about quantum effects? Yeah, I know, it works fine all things considered. Test pilots doin' choreography. Yes, but they're circling a ball with uneven mass concentrations radially emanating away from earth's centre applied to their CG. If they wait long enough, those thrusters will speak when spoken to. That lumpiness aspect of the entire Universe (from quantum to cosmological) is the biggest prob of them all. Time to pull the string. Funny, I just had a flash of Michael Foale on Mir when the remote controlled progress collided with the station and caused all sorts of problems. Those rules are no mean feat. By the book.

Spot on, Chris. The Falcon 9/Crew Dragon combi is America's first 'suitcase' STS. It's taken a while to get there, but I think it took the arrival of a non-indigenous, frontier hunting, trailblazer to get Amerians to pull their fingers out and start, dare I say it, driving westwards once more. I wouldn't say the odor of musk is all-good. Far from it. And poor America had alot of other crap going on (we don't even have safe drinking water). So perhaps it makes sense that those hoarding the wealth had the luxury to start their own space race. It's just a game for "a few good billionaires" who can afford to junk an automobile in space. I thought the booster camera and platform camera did not capture the booster landing. Makes you almost wonder if it didn't land, and they had a camera on an alternate platform... I totally agree. He should've spent his own billions to start up his space company. But as you said the wealth is only shared among the super wealthy. The Musk worshiping and his caviler attitude is infuriating. They've already said the first stage booster which they successfully recovered will go straight into a museum when the whole point of the reusable rocket is to fly at least ten missions. As far as the camera going out right before the first stage landing on the floating platform that was a PR stunt. They didn't want to show the "landing" live in case it crashed or missed the drone. That would be a bad look as the manned capsule continued into LEO. The second THEY saw it landed safely they switched the camera feed back on so everyone could cheer it's safe return. I would like to know if his system is really cheaper than a similar system NASA could've done on their own. I think thousands of people lost their jobs after the Space Shuttle ended and it was decided to privatize manned crewed missions to LEO. I also think they should've gone with the company proposing the mini space shuttle glider design. Being able to land like an airplane and disembark like an airline flight seems much safer, faster and cheaper than going back to parachutes and landing back in the ocean again. Parachutes could fail, the capsule could sink, it takes time to recover the crew and requires lots of ships and vehicles to do so. That all costs extra money. I would also point out Space X couldn't exist without the massive help and infrastructure of our government funded NASA space program. Note NASA and others call Space X "partners". All that said, congrats for a successful mission thus far and so glad everyone is safe.

All that said, congrats for a successful mission thus far and so glad everyone is safe. They found though experience that a reusable shuttle isn’t cheaper. It was suppose to be but too many tiles needed expensive repairs. I don’t think a parachute has ever failed on a manned flight.We haven’t had to recover a water landing since Apollo Soyuz and I’m sure our recovery would be improved. Unfortunately space flight is dangerous and we will lose someone in the future.

Unfortunately space flight is dangerous and we will lose someone in the future. I'm not talking about the old Space Shuttle system. There's plans for smaller gliders that sit on top of the stack like Space X and Russian rockets. But it glides back home. The US military has been doing this for years with it's secret (unmanned) space plane with no issues. https://www.cbc.ca/radio/quirks/a-secret-military-space-plane-is-carrying-an-experiment-to-harvest-power-from-space-1.5590837
