Where can I get a working track for Dragon? SpaceX webcast page isn't working for me.

There isn't one. Don't think any TLEs were grabbed for it between separation and now. Just use the ISS track for a rough estimate. It will be lagging the ISS as its going significantly slower. The ISS passes over the landing zone at roughly 12:27 EST (11 minutes from now).

No, Dragon was ahead, not behind.

Depends on when exactly you check. It's definitely behind now.

Congratulations SpaceX!

How long does it take to get Dragon on a boat?

Congratulations SpaceX!
Now time to reel the dragon in, and I hope this time without power loss, gotta freeze the samples!

The ultimate re-design wasn't until next mission. So good chance still of power loss. This mission only had a patch up job to try and seal things.

Garrett · « **Reply #763 on:** 03/26/2013 04:05 pm »

Going on the SpaceX tweets, it took less than 30 minutes from splashdown to securing of the Dragon by the recovery ship! Impressive.
Anybody have an idea of how long it took the last two, three times?

Joffan · « **Reply #764 on:** 03/26/2013 04:09 pm »

That must be one of the quickest - if not the quickest - splashdown-to-recovery timings ever. 25 minutes or so?

dawei · « **Reply #765 on:** 03/26/2013 04:15 pm »

I think they better start moving the recovery boats a little farther away for future recoveries - don't want a Dragon smashing into the boat itself. Just kidding

Just kidding

Mostly

I assume they rely entirely on the ratio of tiny boat to gigantic ocean to prevent a collision?

Joffan · « **Reply #767 on:** 03/26/2013 04:28 pm »

I'll be expecting them to drop the Dragon straight onto the deck of the Islander next mission.

Ask Iridium 33 and Kosmos 2251 how that worked out.

To be fair, Islander should be able to scoot out of the way.

Recovery vessel position as reported over an hour before splashdown was approx 4 nmi from actual splashdown coordinates reported by SpaceX after recovery, so the recovery boat was within 4 nmi and possibly closer when the chutes opened, and they had time to close range while Dragon descended...

Question: As SpaceX gets additional experience with reentry, splashdown, and recovery of the Dragon, could we start seeing recovery operations a bit closer to the Port of Long Beach? I can understand why they'd want the early missions to splashdown 250 miles from the coast, but wouldn't it be advantageous to get to the point where they can splashdown 30-40 miles off shore to speed up recovery?

The port of Los Angeles, Long Beach, San Diego region is a very heavily traveled area. I suspect the landing location has a lot to do with making certain they don't get Dragon run over by a giant container ship.

This shocking behavior should be reported to the Society for the Protection of Cruelty to Dragons (SPCD).

Parachute in latest pic of Dragon recovery has a rip. I wonder if that happened in-flight or after splashdown.

Looks like Dragon was unable to cut that one chute loose after splashdown (other 2 chutes nowhere to be seen). Rip may have been the result.

huh?
what makes you say that?
perhaps they where just able to grab one chute? perhaps the rest is just out of frame? the ocean is big.
Perhaps they are all 3 attached to the same point, and have sunk with only this one catching wind - the other 2 still being attached, just beneath the water?

Note the boat with the parachute. How would you cut a parachute with Dragon behind it being dragged in that much wind? and then catch the parachute?

Please, can we stop drawing unsupported conclusions from one picture that shows a POST landing picture - by atleast a few minutes - AFTER the chutes have been cut, and flotation devices attached - and there has been atleast SOME post-landing contact with the ripped chute?

IMO a much, MUCh likelier explanation is that the chute ripped during recovery by the very boat next to it.
What makes you go from one picture like this to the conclusion that something failed when cutting the chutes? Does not follow...

No, Dragon is not with the chutes, that's another boat. But since part of the chutes do dip in the water, if there is any wind they could certainly rupture further. They seem to have cut off the chutes faster than during the last splashdown, where Dragon was pulled by the chutes for a bit. (also probably contributed to water intrusion)

My mistake, I thought that was Dragon behind the chute. Bad eyesight. Apologies offered.

It looks like the inflated torn chute is upwind of the Dragon. How did it get there?

picked up by the boat which is reeling it in, after being cut I assume. As to why it is over there- perhaps there is some current going on. perhaps the just pulled the chute away, out of the path of the Islander.
Also, might be that it isnt moving at all - the 2 other chutes could be filled underwater, acting as an anchor. The dragon might have moved more with the wind.

All speculation, of course.

(also, please don't double post
