A SpaceX Dragon cargo capsule is set to conclude a 30-day stay at the International Space Station Tuesday with an automated departure from the orbiting research outpost, a scorching re-entry and splashdown in the Pacific Ocean southwest of Los Angeles.

The ship will be released by the station's robotic arm at 5:03 a.m. EST (1003 GMT), followed by splashdown at 10:41 a.m. EST (1541 GMT).

SpaceX's 19th resupply mission to the space station arrived at the orbiting complex Dec. 8, two days after launch from Cape Canaveral aboard a Falcon 9 rocket.

The Dragon spacecraft -- a veteran of two previous visits to the space station -- delivered 5,769 pounds (2,617 kilograms) of supplies, experiments and hardware for the space station and its six-person crew.

The cargo carried to the station included 40 genetically-enhanced mice, part of a scientific experiment to gauge the effectiveness of an experimental drug to combat muscle and bone atrophy.

The 40 mice are expected to return to Earth inside the Dragon spacecraft Tuesday.

Other payloads delivered to the station last month included a beer brewing experiment and a CubeSat developed by Mexican university students.

There was also an experiment to help scientists investigate flame behavior in confined spaces in microgravity, plus a Japanese Earth-imaging camera and a new lithium-ion battery for the space station's solar power truss.

NASA says the Dragon spacecraft is coming back to Earth with approximately 3,600 pounds (1,630 kilograms) of scientific research specimens and equipment. Besides the mice and a host of biological samples, the capsule will return a failed battery charge/discharge unit retrieved by astronauts on an earlier spacewalk for analysis by engineers on the ground.

Если я правильно понял, то Драгон уже отстыковался сегодня от МКС? Во сколько? Приводнение, как я понял тоже сегодня вечером? Во сколько?

Ещё не отстыковался - висит на руке манипулятора, отпустят около 13:03 ДМВ, приводнение - примерно в 18:41 ДМВ. Отрыв от станции рукой манипулятора - был ориентировочно в 10:20 ДМВ (возможны разночтения...  )

Live Now on NASA TV Dragon Prepares for Station Departure

The SpaceX Dragon cargo craft is pictured moments before its release from the Canadarm2 robotic arm on June 3, 2019.

NASA Television coverage is underway for departure of the SpaceX Dragon spacecraft from the International Space Station. The spacecraft is scheduled for release at approximately 5:03 a.m. EST today.

Dragon will be released from the Earth-facing port of the Harmony module after flight controllers at mission control in Houston deliver remote commands to the station's Canadarm2  robotic arm. Expedition 61 Station Commander Luca Parmitano of ESA (European Space Agency) will back up the ground controllers and monitor Dragon's systems as it departs the orbital laboratory.

After firing its thrusters to move a safe distance away from the station, Dragon will execute a deorbit burn to leave orbit, as it heads for a parachute-assisted splashdown in the Pacific Ocean, 202 miles southwest of Long Beach, California, at approximately 10:41 a.m. (7:41 p.m. PST). There will be no live coverage of deorbit burn or splashdown.

A key component being returned aboard Dragon is a faulty battery charge-discharge unit (BCDU), which failed to activate following the Oct. 11 installation of new lithium-ion batteries on the space station's truss. The BCDU was removed and replaced during a spacewalk Oct. 18 by Expedition 61 flight engineers Christina Koch and Jessica Meir of NASA. The unit will be returned to teams on Earth for an evaluation and repair.

Dragon launched on the SpaceX Falcon 9 rocket Dec. 5 from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida, and arrived at the station two days later with almost 3,400 pounds of science, supplies and cargo on SpaceX's 19th commercial resupply mission to the station for NASA.

Dragon is now flying on its own, having been released from the grasp of the space station robotic arm at 5:05 a.m. EST (1005 GMT) as the craft flew at an altitude of around 271 miles to the southwest of Australia.

The Dragon spacecraft has finished its second departure burn. A yaw maneuver is coming up next, then a final departure maneuver is planned.
