I wonder how long ago these folks got fed up with social distancing jokes...

Went off without a hitch today. Will dock with the space station at 10:27am tomorrow.

Mack, question for you. If weather can impact the launch (almost did again today) and we all know it rains every afternoon in Florida sometime between 2 and 7 pm, why not do this at like 9am?

Launch windows are based on the orbit you are launching to and for an ISS dock you also have to time the phasing of the ISS orbit.

They could have wider windows (so instead of launch only at 2:33 or whatever it was,can launch anywhere from 2:30 to 3:30) but then they'd need to carry a lot more propellant on the 2nd stage and capsule so you can alter the phase of your orbit if you launch at a different time than the ideal time. Cheaper to just wait until the next opportunity the timing is ideal. Carrying mass is incredibly expensive, so anything to lighten the load is worth doing.

If this stuff interests you at all, and you like video games, check out Kerbal Space Program. It's kind of like Sim City meets NASA. The physics is pretty legit.

Learn something new everyday. Thanks man. I figured the very specific time (3:22) had a scientific reason. I watched the two hour pre show Wednesday before the cancelled launch. Really fascinating. I feel like this is a pretty big deal that is getting buried by the bad stuff going on in the world. Unfortunate. I didn’t even hear about it until Wednesday morning. Feel like in the past a space launch was must see tv.

It was interesting watching the soft-lock bladder compress to where the hard-lock latches could grab... not so much watching it as learning it works that way... while watching it work from outside in space in HD...

 

Too bad we didn't have HD for Apollo... instead we got fuzzy B&W while listening to "One small step for khhhck man and khhckt khhhck step for mankind..."

 

ps:  How to spell the sound of radio static?
