It's a familiar tail number here:

The parachute has a pretty large rupture. Is that expected (maybe something that happens after splashdown) or is that an anomaly? The chute seems well inflated, so I assume, if the tear occured during descent, that the chute still managed to do its job..

That's not Dragon with the parachute, BTW. It's another boat. But perhaps the point was to point out the rupture in the parachute?

The chutes do have some kind of side vents to allow the three chutes to not run into each other - this might be what has torn further here.

This blow up of the picture posted above of the three parachutes, right at splash down, can help. They all look fully inflated and no tear apparent from that angle.

...A boat will take the Dragon capsule to a port near Los Angeles...

I sure would love it if they used the ports name since its my home town. Its San Pedro CA.

I get a real Apollo vibe from those photos!

Me too, but with the added thought that it's half the price for twice the crew!* Okay, maybe be getting a little ahead of myself

Congrats to SpaceX once again!

* Saturn 1B cost 1972US$55M or 2013US$306. DragonRider projected cost US$140M for 7 seats. All figures from Wikipedia: YMMV.

Congrats to SpaceX. Fantastic mission and great coverage from start to finish.

I'm optimistic about SpaceX on days like today so I might as well enjoy it for as long as it lasts

Thanks to all who contributed to this live thread. I was unable to monitor the action today in real time, but it was great to read through the whole thread after the fact and catch the excitement. Sort of like watching a football game on DVR. (Don't tell me who wins!)

Congratulations, SpaceX!

joek · « **Reply #229 on:** 03/27/2013 12:24 am »

Congratulations SpaceX on another great mission. Success speaks for itself, and we're all looking forward to more. Thanks again to all the NSF folks for the coverage, and especially the L2 extras.

Dragon CRS/SpaceX-02 - refined value for splashdown: 30°.52 north, 120°.05 west

https://twitter.com/Zarya_Info/status/316606775149355009

Recovery ship position over an hour before splashdown: 30.53/-120.14
Reported splashdown position: 30.52/-120.05
delta = 4 nmi

Whats the error range on that? assuming +/- 0.01 degrees on both.

If I didn't flub the calc... Give or take ~0.85NM (~1850 meters per minute of arc).

Some pictures of the unberthing have been uploaded. The capsule yellowed.

If I didn't flub the calc... Give or take ~0.85NM (~1850 meters per minute of arc).

At that position:

0.01 deg lat = 0.6 nmi
0.01 deg long = 0.5 nmi

By the way, I used this calculator for the earlier delta=4 nmi calc:

http://www.nhc.noaa.gov/gccalc.shtml

When I plug those same coordinates in now, I get delta = 5 nmi, so I may have transposed a digit earlier. I think the 5 nmi is correct, not 4 nmi.

5 nmi = 9200 meters approximately, and Lee Jay earlier posted his photo analysis by which he estimated the splashdown photo was taken at a distance of 9100 meters +/- 10%, so good agreement between those 2 numbers.

In case there was any remaining question about the waterproofing, a Mollytweet from last night:

There was a girlish scream of triumph/delight when the engineer in charge of waterproofing discovered how well *his* stuff worked. #Dragon

MEDIA ADVISORY: M13-053

NASA, SPACEX DISCUSS DRAGON MISSION TO SPACE STATION

WASHINGTON -- NASA and SpaceX will host a teleconference for news
media at 1 p.m. EDT, Thursday, March 28, to discuss the Tuesday
return of the company's Dragon spacecraft from a cargo mission to the
International Space Station.

A trove of scientific research was among more than 2 tons of cargo
Dragon brought back to Earth. Included are investigations that could
aid in food production during future long-duration space missions and
enhance crop production on Earth. Others could help in the
development of more efficient solar cells, detergents and
semiconductor-based electronics. Dragon also brought back several
research samples that will help scientists continue to examine how
the human body reacts to long-term spaceflight. The results will have
implications for future space exploration as well as benefits here on
Earth.

The teleconference participants are:

-- Charles Bolden, NASA administrator
-- Julie Robinson, International Space Station Program scientist
-- Elon Musk, chief designer and CEO, SpaceX
-- Gwynne Shotwell, president and COO, SpaceX

For dial-in information, journalists must contact Trent Perrotto at
[email protected] or 202-358-1100 by noon EDT, Thursday,
March 28.

Audio of the teleconference will be streamed live on NASA's website

Two tons of down cargo is a lot.

Will this clear the backlog at the ISS or is there more that needs transport down soon?

Based on their downmass requirements in the current form of the contract they have quite a bit more to return inside. This is with current contracted flights since contract options have not yet been used.

Hey the American Islander just pass the breakwaters at Long Beach. Figure they will docked within about 25 min if it's like CRS-1 mission. According to the marinetraffic site.
