Love the new "Space" suits and the touch screen panel inside the capsule. This is going to be amazing. My prayers with the brave astronauts.

The space suits, UI, design of it all feels exactly what I’ve though the future of space technology would be. Maybe not all the way there yet, but a great leap from hundreds of manual switches and raw aluminum of the shuttle era.

*Pending weather

On this note, does anybody know what the weather thresholds are that would cancel the launch? I mean, the current forecast suggests it will almost definitely be raining at 433pm Eastern, and wind will be around 10 mph. Is some amount of rain tolerable? How much wind is acceptable?

Here’s some information on the Space Shuttle Weather Launch Commit Criteria. There are probably some added bits for the water recovery incase of an abort with Crew Dragon. https://www.nasa.gov/centers/kennedy/pdf/531435main_weather-...

Edit: and for the falcon 9 (non crew) https://www.nasa.gov/pdf/649911main_051612_falcon9_weather_c...

I get that you dont want to fly a giant rocket full of liquid oxygen and other explosives into a thunderstorm or hurricane, but what are some practical reasons for postponing a launch due to weather. As I (hardly) understand once you get high up in the atmosphere there is high wind even on a clear day, does rain matter that much?

The weather needs to be good enough for a safe recovery downrange if there's an abort.

The cold war is back, the fashion is back and out of all the things that are back I am glad that the USA is back in space flights.

Wish you the best luck and hope that this will lead to some serious competition. Soyuz is great but we need to do more as species.

Various reasons, well explained here (in several answers, including one pointing out that Challenger blew up in part due to cold weather): https://space.stackexchange.com/questions/4967/why-are-rocke...

I would think by far it’s for crew safety.

Recovery due to an in-flight abort would be difficult in rough seas and weather if they had to be plucked out of the Atlantic.

The aerostructure of the falcon 9 can only withstand so much side loading due to aerodynamic forces and wind before exceeding the operational limits of the rocket (body to keep it all from breaking apart, and the engines working hard to keep them on the correct trajectory).

The space suit looks like it's made for a Halloween party. It looks kind of not flexible and fragile.

The touch screen panel is surely very cool.

Anyone know of any other tool like this that might give an idea of where in the sky to look based on your location? https://james.darpinian.com/satellites/?special=starlink-lat...
