First pressure-check failed. pressure rising slowly.

Swanny tried to partially open and re-close an MPEV (didn't get which one, I think it was node 2 related, maybe the node 2 hatch MPEV).

Now re-evacuating the vestibule, and restarting pressure checks.

Offline InfraNut2

Swanny reporting pressure readings of 1.2 at 2 min and 1.9 min at 3 min. Houston likes them.

While writing this: 3.0 at 5 min. Houston: "Fantastic, sounds like we made it"

edit: CCP = Crew Command Panel (for Dragon commanding--connected to CUCU; there is a similar separate command panel "HCP" for HTV/Cygnus connected to PROX. There is similar functionality for ATV but that system is more different I think)

Dragon grappled. Breaks on.

Screencaps taken just before and just after.

(Have had problems following the recent conversation  on the ISS feed. The comm seems noisy/distorted and Swanny's gruff and nasal voice does not carry well through the noise/distortion. Also they often refer just to procedure steps by number. I tried and failed to locate the procedures on L2 -- my search-fu is not at its best today).

I have not seen or heard any unberth time. Neither the coverage announcement or the NASA TV ISS coverage friday mentioned it -- only the release time was mentioned.

The arm was moved into position friday, but they must have stopped at the pre-grapple position, unless I misundersood the comm just now.

There was a also a CCP check friday, so the (very quick) one today must have been a quick double-check.

edit: added screencaps from the 2 mentioned preparation activities on friday.

Aiii. Already moving the Dragon to the Demate position (~1.75m back off).

Nothing noticed on the loop after the de-mate message, so I thought they had some set-up to do first, but they went right ahead and did it immediately.

Now obviusly maneuvering Dragon from Demate position to Release position, though nothing said on the loop. The release position is more than 10m out. IIRC they stretched the arm out to not far from its maximum reach last time.

Pretty lens glare effect.

Always someone asking this every time. Maybe the link to the live iss stream plus main nasa tv page should be posted in the OP in the future? So you all know:

An overview of "Live NASA TV/Camera Audio/Video Links" is always pinned at the top of the "General Discussion" section, in the hope of reducing questions like this.

If that was too overwhelming: The iss feed is found at the right side the NASA TV main window, under the link "Space Station Views". Or see it directly on ustream: http://www.ustream.tv/channel/live-iss-stream

Well that was somewhat boring (slow text updates, not the mission), especially if you've been spoilt by the excitement and drama of Shuttle returns, but boring also means no issues, and no issues means good news!

What is most important is this vehicle has another success under her belt, which helps the path to commercial crew and the return of US independence for crew launch that was lost after Shuttle was retired.

It's all interlinked when you think about it.

Yes many thanks for the updates. I've commented elsewhere that this relatively unsung success in returning things deserves more attention. It's a sign that something is working right somewhere at Spacex. It helps you to feel that launch and recovery of the boosters will reach the same kind of routine eventually. Well done.  8)

All true but we should also not forget those crowds of scientists on the ground waiting months and years to receive samples and results of their experiments from ISS to evaluate them and conclude their research. Let's keep in mind the main purpose of ISS - orbiting science laboratory. :)

SpaceX Dragon Spacecraft Returns Critical NASA Science from Space Station

SpaceX's Dragon cargo spacecraft splashed down at 3:05 p.m. EDT Sunday, in the Pacific Ocean, approximately 300 miles west of Baja California, returning more than 3,500 pounds of NASA cargo and science samples from the International Space Station.

A boat will carry the Dragon spacecraft to a port near Los Angeles, where it will be prepared for a return journey to SpaceX's test facility in McGregor, Texas, for processing. Some cargo, including a freezer packed with research samples collected aboard the space station, will be removed at the port in California and returned to NASA within 48 hours.

"The space station is our springboard to deep space and the science samples returned to Earth are critical to improving our knowledge of how space affects humans who live and work there for long durations," said William Gerstenmaier, associate administrator for human exploration and operations. "Now that Dragon has returned, scientists can complete their analyses, so we can see how results may impact future human space exploration or provide direct benefits to people on Earth."

Investigations included among the returned cargo could aid in better understanding the decreased effectiveness of antibiotics during spaceflight while also improving antibiotic development on Earth. Others could lead to the development of plants better suited for space and improvements in sustainable agriculture.

The T-Cell Activation in Aging experiment, which also launched to space aboard Dragon, seeks the cause of a depression in the human immune system while in microgravity. The research could help researchers develop better protective measures to prevent disease in astronauts.

Dragon is the only space station resupply spacecraft capable of returning large amounts of cargo to Earth. The spacecraft lifted off from Cape Canaveral Air Force Station in Florida April 18, carrying approximately 5,000 pounds of supplies and science investigations to the space station. The mission was the third of at least 12 cargo resupply trips SpaceX plans to make to the space station through 2016 under NASA's Commercial Resupply Services contract.

Congratulations to SpaceX for a success they made look easy, which we all know it is not.

I wish they would give us a clue as to how close the splashdown was to the target point.  On the first reentry SpaceX said it was 0.8 km off, but since then there hasn't been any additional reports.  It has some bearing on their plans for propulsive landing.  If they can repeatedly hit under a kilometer, which would be several times more accurate than Soyuz, they should have little trouble hitting a pad, especially without drifting under parachutes.

Anyone at SpaceX care to give us that one little datum?

edit: Also, any report on the SpaceX built scanning lidar system used on this mission instead of the redundant DragonEye flash lidar?

Those pictures bring up a question I've had about the parachutes.  Are they cut off and dispensed with, are they packed up separately and reused?  Are they recovered, inspected, and then discarded?  What happens to them?

That could negatively affect the failure investigation into the EMU that came down on Dragon - could be a lot harder to find evidence of water leakage after the entire suit has been soaked in sea water!

If Dragon is airtight (which we know it is), then I really struggle to see how the water can get in.

That thing puzzled me since first reported. I heard rumors about leak through "pressure-equalization valve", ok the Dragon obviously can have more pressure inside, but may be it is not allowed to have LESS pressure inside, so could it be designed to suck in outside air on the way down? Really puzzled...

Edit: you may need to equalize pressure before opening the hatch, both on ISS and back on Earth. So there should really be some valve connecting inside to outside.

It's reported in SFN that a leaking pressure relief valve may be the culprit.

Thanks for the link. Quoting the video (as best I can):
Quote
SpaceX did incur a minor water excursion. (sic) It has not caused us any impacts that we know of. Obviously we will be looking into that. The Dragon will be moving from the Hawthorn area, ah the Long Beach area to McGreggor. Again, no impacts that we're aware of.
So bummer there was any water, but at least according to NASA it's not caused any issues.

Of all the things I would expect to be hard about space, keeping water out of the capsule was not one of them (ignoring Liberty Bell 7). The more I know, the less I know that I know...

Initially, there was speculation the water source could have been one of several containment bags of water that NASA was returning on Dragon as part of its investigation into the July 16 water leak into the helmet of a U.S. spacesuit worn by Italian astronaut Luca Parmitano. Bags containing several gallons of water from the ISS airlock were returned to Earth for analysis to help conclude the investigation
Both of those statements suggest water in the pressure vessel.

Simple test: Is the water fresh or salty?

It took 11 hours to fish the capsule out of water? SpaceX needs to change this contractor and use bigger ship as well. Imagine this were a crewed dragon...


I wonder what on earth can take so long.

Sea swells in the area were around 8ft with 15-20knot winds according to the closest bouy.. Trivial task?

Just proofs once again that landing on land is the way to go.

Landing on land requires firing hypergolic thrusters - if there is a leak, would you want to contaminate the inside of the craft (experiments, people) with those?

The hypergolic thrusters are there, whether you use them for landing or not. They could leak either way. In case of a leak, it actually be beneficial to use most of the hypergolic fuel for the landing. So there is less left to leak out.

I would not expect the capsule to leak either & the mfr will doubtless resolve this, but

(1) years of experience sailing proved to me that water is very difficult to keep out (2) if you look at the splashdown image, note the size of the splash - there is a great deal of hydraulic pressure in that single event. There will be a pulse caused at each roll caused by waves. Even a tiny leak would add up over 11 hours.

Recovering things from the sea is not trivial. You get motions of several meters between two vessels. The last thing you want to have happen is a collision between the capsule and the recovery vessel. If they waited 11 hours it would  be to allow sea conditions to improve to the point that they would do it safely with low risk to capsule and crew.

i shall go back to lurking :-)

You are forgetting the water is believed to have made it in through a pressure equalization valve. On land, Hypergolic fumes can do the same thing.
If you're happy and you know it,

And they can do the same in the water...

So it does look cleaner than after the last two flights? I thought the same thing, but was not quite sure. Would like to see more pics from more angles.

Compared to a Soyuz, which looks like it just barely makes it through atmo, it's clean as a whistle.

Yup. Already happened once on a manned mission: Apollo Soyuz Test Project. The RCS was inadvertently left on during descent, and highly toxic nitrogen tetroxide was sucked into the spacecraft thru a cabin air intake as it drew in outside air. Crewmember Brand briefly lost consciousness, while crewmember Stafford retrieved emergency oxygen masks, put one on Brand, and gave one to crewmember Slayton.

Can you imagine if that'd been a DragonRider and you'd been inside that thing?  :o There'd be liquid in the compartment all right, but it wouldn't be water.  :P
