Still waiting for word from SpaceX (but they usually wait until Chutes), but Dragon will now begin being dragged back to Earth by gravity, will next sep the Trunk, which will also mark a farewell for OPALS, MISSE and RRM.

Cool. All is going well:

SpaceX;
Dragon's deorbit burn is complete and trunk has been jettisoned. Pacific Ocean splashdown with critical @NASA cargo in ~30 minutes

Entry Interface (EI). Dragon is being protected by her PICA-X TPS (Thermal Protection System) heat shield.

Good splashdown of Dragon confirmed, carrying @NASA science and research cargo back from the @Space_Station.

Dragon Splashes Down in Pacific Ocean
Posted on March 19, 2017 at 12:11 pm by Mark Garcia

SpaceX’s Dragon cargo craft splashed down in the Pacific Ocean at 10:46 a.m. EDT, about 200 miles southwest of Long Beach, California, marking the end of the company’s tenth contracted cargo resupply mission to the International Space Station for NASA.
Expedition 50 astronauts Thomas Pesquet of ESA (European Space Agency) and Shane Kimbrough of NASA released the SpaceX Dragon cargo spacecraft from the International Space Station’s robotic arm right on schedule, at 5:11 a.m.
A variety of technological and biological studies are returning in Dragon. The Microgravity Expanded Stem Cells investigation had crew members observe cell growth and other characteristics in microgravity. This information will provide insight into how human cancers start and spread, which aids in the development of prevention and treatment plans. Results from this investigation could lead to the treatment of disease and injury in space, as well as provide a way to improve stem cell production for human therapy on Earth.
Samples from the Tissue Regeneration-Bone Defect study, a U.S. National Laboratory investigation sponsored by the Center for the Advancement of Science in Space (CASIS) and the U.S. Army Medical Research and Materiel Command, studied what prevents vertebrates such as rodents and humans from re-growing lost bone and tissue, and how microgravity conditions affect the process. Results will provide a new understanding of the biological reasons behind a human’s inability to grow a lost limb at the wound site, and could lead to new treatment options for the more than 30 percent of the patient population who do not respond to current options for chronic non-healing wounds.
The Dragon spacecraft launched Feb. 19 on a SpaceX Falcon 9 rocket from historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida, and arrived at the station Feb. 23.

4 hours since splashdown. How long usually until they get it on the boat?

Edit: actually 5 hours.

Per a spaceflightnow story, 104 kg of EVA equipment was brought home on Dragon. Does anyone (hi, Pete?) know what that was? Substantial - sounds like an EMU or at least a PLSS or HUT or something

Edit: Was not an EMU, per message to me from the story's author.

Has anyone seen a source for what time Dragon was unberthed from the station? I saw a twitter post suggesting 05:30 UTC, but the NSF story suggests it was the previous day, and Dragon was left suspended from Canadarm2 overnight.

That might have been my post. I later amended to at least before 0130 UTC.... but could be earlier.

Over in the Dragon 2 thread there was the following discussion (which has been condensed):

NASA TV: Release of SpaceX Dragon Capsule From The ISS

Heard the following comments during the Dragon unberthing operations, regarding a 90 minute test performed by Dragon in preparation for crew Dragon.  The comment is located between 6:28 and 7:10 in the video linked above.

Quote from: NASA TV Commentator
Engineers called (for) an IDA selfie.  Actually manoeuvring Dragon in front of the future docking port of the Commercial Crew vehicles.  The Commercial Crew vehicles that will be carrying astronauts from the United States and other partner agencies launching from the United States in the future.  Dragon using its thermal images and LIDAR just to help better understand the reflective environment of that IDA, basically a test to acquire some data that will be used for the future crewed Dragon during what's known as its proximity ops.  Those close in operations right before actual docking... and that took about 90 minutes, and then once that was complete ground controllers again commanded the Canadarm2 which is still holding Dragon into its release attitude where it has been sitting for the last several hours..

My understanding is that the Canadarm2 was used as a selfie stick and Dragon was the camera used to take various "photos" of the IDA.

So Dragon appears to have spent at least "several hours" on the Canadarm2.

What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

Spaceflight101 reports a unberthing time of around 21.20 UTC on Saturday.

Four groups of four bolts were released and capture latches opened to demate Dragon from the Earth-facing port on the Harmony module at around 21:20 UTC on Saturday. Under the control of Canadarm-2, Dragon was moved to its release position in the overnight hours to be in position when the crew got up on Sunday.
