How long will the approach to the ISS take? Previous unmanned Dragon missions take ~1 day to approach and dock but I can't imagine they will subject the astronauts to the same.

They've got it down to a few hours. https://en.wikipedia.org/wiki/Soyuz_TMA-08M#Expedited_docking https://en.wikipedia.org/wiki/Soyuz_TMA-08M#Expedited_dockin... It used to take days. Not fun in a tiny capsule like Soyuz, I'd imagine. https://www.engadget.com/2013-03-29-soyuz-cuts-travel-time-to-iss.html https://www.engadget.com/2013-03-29-soyuz-cuts-travel-time-t...

Similar - about 18-19hrs before docking. You should be able to watch it live tomorrow morning. It's funny that it takes that long, since they could theoretically make it up there in like half an hour or so. Here's a good overview of what's gonna happen today: https://www.youtube.com/watch?v=Lr_zfpzGxQQ https://www.youtube.com/watch?v=Lr_zfpzGxQQ

  Thanks, that was a really good mission rundown. On a separate note, it's amazing how Tim has built such a brand in such a short time, I remember when he started out a couple of years ago.

    He's been culturing the persona for about 5 years, and youtubing since 2017

  He said exactly what I was thinking: Initiate ludicrous mode on the way to the launch site.

  Half an hour is very optimistic! The Soyuz expedited rendezvous takes hours. https://space.stackexchange.com/questions/21819/how-did-soyuz-ms-04-reach-the-iss-in-only-6-hours https://space.stackexchange.com/questions/21819/how-did-soyu...

    It's possible physics-wise, I believe. They do a couple orbits gentle approach first because a) it's not a great idea to barrel towards the ISS at speed and b) it gives an opportunity to check for things like "did our solar panels deploy" and "do we need to land because the air is leaking out".

This video explains the whole mission from the astronaut's point of view in about 15 minutes. https://www.youtube.com/watch?v=Lr_zfpzGxQQ https://www.youtube.com/watch?v=Lr_zfpzGxQQ He has lots of great videos including some very well produced content on rocket engine design, starship etc. The short answer to your question is just over 19 hours until docking, and then I think another 2 hours after that until the hatch opens.
