Quoted from wrb1977:Same junk
He was joking, and you apparently missed a chance to have a good laugh.

Quoted from mof:S10 now
wait - when does it launch?
What are essential watches from previous launches?
I just enjoyed
S5 150m hop success
S8 looked close !

Quoted from jhanley:How far can it venture from the base lander?
This is my understanding.

Does anyone know why they wait until the last possible second to come out of the belly flop?
Why not give themselves an extra 5-10 seconds?
It just doesn't seem like they are giving themselves enough time to have a super soft landing.
I realize today was 98% perfect, but... that was quite a jarring bounce.
It's a 20-second landing process, HOLY cow:
landing -20 seconds 3 engines light to undo the belly flop (4 seconds)
landing -16 seconds 3 engines providing vertical force to drastically slow descent (4 seconds)
landing -12 seconds shut off 2 engines (12 seconds with 1 engine)
Visibly with 1 engine, it "seems" like the descent is a static speed, as if 1 is simply not enough to get it done, UNLESS you had run 2 engines for 1-2-3 more seconds to get the velocity closer to zero before you went to 1.
Just wondering!

Quoted from Pinballlew:Here’s Space X feed too
T minus 5 minutes. What is the mission? Can they even leave their seats? 3 days in orbit? What for? Does anyone get this one?
Quoted from Pinballlew:science experiments to conduct
who has a good link for what the current crew is doing?
Quoted from Pinballlew:how much coverage
Did anyone cover the basics?
Do they keep the suits on the whole time?
What about number 1 and number 2?
What about the smell from number 2? I bet they forgot to bring matches...
Some quick math here -- 4 people one space, means roughly every 2-6 hours we're talking massive stink bombs.

Tell your relatives you are busy on December 18.
Something wonderful is going to happen...
Setting up the orbit for that guy looks sick.

Quoted from mbwalker:huge deal
Will maintenance be easy to do if it has that weirdly set up orbit?

We have to wait until Summer to see what JWST learns?
