Looking back at SpX-1, it was two hours from capture to berthing

Riiight ... So much for my plan to wake up one hour prior to capture and watch the last 100 or so meters. I woke up, checked in here, and the LEE was driving to capture Dragon ... Then the Ustream feed wouldn't come up in time ... :/

So, as consolation, let me document here what happened, compared to the estimates from yesterday. Our best guess on Sunday evening as to the approach timeline was based on the CRS-1 approach plan, since that was the best we had. (Martin/MP99, you claimed overnight that it was in the press kit; it is not)

From Sunday evening:

Here is my rough estimate for approach and berthing timeline.
4:41am ET = 250 meter (820 foot) departure
5:49am ET = 30 meter (100 foot) departure
6:07am ET = Capture point arrival
6:31am ET = Capture (announced plan)
Times are obviously rough estimates. I just needed to know what time to set my alarm clock for.

I just now went through the thread and gathered the actual times:

4:06am ET = 250 meter (820 foot) departure
(35 minutes earlier than my estimated plan above)
5:06am ET = 30 meter (100 foot) departure
(43 minutes earlier than my estimated plan above)
5:22am ET = Capture point arrival
(45 minutes earlier than my estimated plan above)
5:31am ET = Capture
(60 minutes earlier than announced plan yesterday)

So, now we know that when NASA announces an estimated capture time for the next day, there is at least a full hour of wiggle room in that. Obviously they might run behind the timeline due to issues, and I expected they might run a little ahead, but not a full hour. Contrast with the shuttle days, where they'd be nowhere near this early, rather just staying right on the timeline.

EDIT: Jim points out that this was an off-nominal mission; if nominal they would not have run early; fair enough, we'll see.

Not complaining, just documenting it for the future. Congratulations SpaceX!

Sorry, you're right - lists the events but not the times.

cheers, Martin

ISS crew very eager to do some exercise!

Arm movements during next daylight pass.

Wrong conclusion. Because of delay and replanning, that is the reason for the time difference. This would not be applicable on a nominal mission

You can see the planet reflected in the window.

Anyone know why robot arm engineers in Houston and in Saint-Hubert, Quebec, are doing the remote control installation of the Dragon capsule on the space station instead of the astronauts at the ISS? Is this a demonstration of increased capabilities? Or a plan for future ISS operations? Just curious...

Joffan · « **Reply #197 on:** 03/03/2013 11:02 am »

Looks like hold at pre-install...

confirmed

‏@SpaceX
Dragon now targeted to berth w/ISS in the next 2-3 hrs.

(Depends how long they want to stay in pre-berth, otherwise it'll be a lot sooner than that.

Still at hold, note Dragon ~~wings~~ panels in berthing attitude
