NASA passed a major milestone Friday in its goal to restore America’s human spaceflight capability when SpaceX’s Crew Dragon returned to Earth after a five-day mission docked to the International Space Station.
NASA Breaking News

At 2:32 a.m. EST, Crew Dragon undocked from the International Space Station to begin the final phase of its uncrewed Demo-1 flight test. The spacecraft is slowly maneuvering away from the orbital laboratory into an orbital track that will return it and its cargo safely to Earth.
NASA will continue to provide live coverage until Crew Dragon is out of the immediate area of the station and will resume at 7:30 a.m. for the reentry, splashdown, and recovery.
In about five hours, the Crew Dragon will separate from its trunk whose exterior contains a solar array that provided power to Dragon and a radiator to reject heat.
Following separation, Crew Dragon’s thrusters will initiate the spacecraft’s deorbit burn at about 7:52 a.m. The 15-minute, 25-second burn will place the Crew Dragon on its final re-entry path into Earth’s atmosphere. The spacecraft is expected to splashdown in the Atlantic Ocean at about 8:45 a.m., its speed slowed by an enhanced parachute system in which drogue parachutes will deploy about four minutes before landing to unfurl four main chutes less than a minute later.
After Crew Dragon lands in the Atlantic Ocean, SpaceX’s recovery ship will recover it and return it to Port Canaveral, Florida to conclude its mission.
SpaceX’s inaugural mission with NASA’s Commercial Crew Program is an important end-to-end to test of the new system’s capabilities.
More details about the mission and NASA’s commercial crew program can be found in the press kit online and by following the commercial crew blog, @commercial_crew and commercial crew on Facebook.

The SpaceX Crew Dragon’s hatch is closed and the stage is set for the Commercial Crew Program’s first undocking and return to Earth Friday. As NASA and SpaceX get ready for Friday’s splashdown, the Expedition 58 crew continued exploring a variety of space physics phenomena aboard the International Space Station.
The uncrewed SpaceX DM-1 mission has one final milestone and that is the safe return to Earth with a splashdown in the Atlantic Ocean around 8:45 a.m. EST Friday. The Crew Dragon will undock Friday at 2:31 a.m. from the Harmony module’s international docking adapter. NASA TV will broadcast the departure and return activities live.
The first commercial crew vehicle from SpaceX will be bringing back over 330 pounds of science gear, crew supplies and station hardware. It delivered almost 450 pounds of materials to resupply the station crew on March 3.
Science took precedence as usual aboard the orbital lab today as SpaceX prepares to welcome its Crew Dragon back on Earth.
NASA astronaut Anne McClain spent Thursday morning setting up hardware to explore ways to improve the production of higher-quality semiconductor crystals. Afterward, she relocated the Alpha Magnetic Spectrometer laptop computer that researches cosmic rays and antimatter from the Columbus lab module to the Destiny lab module.
Commander Oleg Kononenko worked throughout the day on a Russian-European experiment researching plasma physics. The Plasma Krystal-4 study observes plasma crystal formation that could inform future research and spacecraft designs.

A Google translation of the AMSAT-Francophone post says:
The AMSAT-Francophone and Electrolab have deployed a ground station to operate the QO100 transponder in DATV.
The “broadcast DATV” team led by Yannick Avelino and with the support of Evariste F5OEO has developed the station that will broadcast live the conferences of the second amateur radio space meeting March 9-10, 2019. The team was in contact with AMSAT-DL and AMSAT-UK for permission to operate the satellite during these days.
