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.

Crew Dragon Set for Friday Splashdown Amid Space Physics Research

Crew Dragon Set for Friday Splashdown Amid Space Physics Research

The uncrewed SpaceX Crew Dragon spacecraft is the first Commercial Crew vehicle to visit the International Space Station. Here it is pictured with its nose cone open revealing its docking mechanism while approaching the station’s Harmony module on March 3, 2019.

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.

Vice President Calls Station, Crew Dragon Packed for Friday Return

Vice President Calls Station, Crew Dragon Packed for Friday Return

Vice President Mike Pence and NASA Administrator Jim Bridenstine called up to the Expedition 58 crew today. Astronauts Anne McClain and David Saint-Jacques were on hand to talk about their mission success and the arrival of the first Commercial Crew vehicle, the SpaceX Crew Dragon.

The Crew Dragon is being packed and readied for its return to Earth on Friday. In the midst of NASA’s first Commercial Crew mission, the crew members continued more space research and practiced an emergency drill today.

Saint-Jacques of the Canadian Space Agency transferred cargo in and out of the Crew Dragon today. Over 300 pounds of science gear, crew supplies and station hardware will be retrieved from Dragon after it returns to Earth.

The Crew Dragon will undock Friday at 2:31 a.m. EST from the Harmony module’s international docking adapter. It will parachute to a splashdown in the Atlantic Ocean around 8:45 a.m. EST. NASA TV will cover all the activities live.

McClain from NASA worked in the Destiny laboratory module today stowing science hardware after working on the Microgravity Sciences Glovebox. She then began collecting and readying more experiment hardware that will test ways to improve the production of higher-quality semiconductor crystals.

Both astronauts then joined Commander Oleg Kononenko from Roscosmos to practice an emergency evacuation of the International Space Station. The trio wore breathing masks, entered the docked Soyuz spacecraft and prepared for a return to Earth in the unlikely event of a critical emergency aboard the orbital complex.

The three Expedition 58 crew members are back to normal operations today with the newest SpaceX Crew Dragon spaceship integrated to the International Space Station. Dragon will leave the station Friday as the next crew prepares to launch on March 14.

Astronauts Anne McClain and David Saint-Jacques called down to mission controllers today to discuss Crew Dragon operations. The duo also linked up with SpaceX personnel throughout the United States describing life on orbit and their impressions of the new crew vehicle.

McClain started today resizing U.S. spacesuits ahead of a set of spacewalks planned for March and April. She later worked on life support systems and plumbing maintenance in the Unity and Tranquility modules.

Saint-Jacques collected station water samples for microbial analysis. He then inspected tethers the astronauts will use to stay attached to the station during the upcoming spacewalks.

Commander Oleg Kononenko replaced fuel bottles used during experiment operations inside the Combustion Integrated Rack. The veteran cosmonaut also explored low temperature gas mixtures for the Plasma Krysyall-4 experiment collaboration between Europe and Russia.

The SpaceX Crew Dragon undocks Friday at 2:31 a.m. EST. Splashdown in the Atlantic Ocean is scheduled around 8:45 a.m. EST. NASA TV will cover all the activities live after closing the hatch Thursday.

On the other side of the world in Kazakhstan, three new Expedition 59 crew members are in final training awaiting their launch to the station. Commander Alexey Ovchinin and Flight Engineers Nick Hague and Christina Koch are set to blastoff March 14 at 3:14 p.m. and dock less than six hours later to their new home in space.

Expedition 58 capped off its busy weekend with additional outfitting for the SpaceX Crew Dragon, which had only completed its hard dock to the International Space Station yesterday morning as part of the Demo-1 uncrewed flight test.

After opening the hatch between the two spacecraft, the crewmates configured Crew Dragon for its stay while barnacled to the orbiting laboratory. This work included installation of the intramodule ventilation system, which helps cycle air from Crew Dragon to station. The crew members ticked off additional items from their checklist, also installing window covers and checking valves before taking part in a welcoming ceremony for the visiting vehicle at 10:45 a.m. EST Sunday, which aired on NASA Television.

Today, NASA astronaut Anne McClain, David Saint-Jacques of the Canadian Space Agency and Russian cosmonaut and Expedition 58 Commander Oleg Kononenko went over emergency procedures specific to Crew Dragon’s stay in orbit. While Crew Dragon is designed to remain docked to the space station for up to 210 days, this test of the spacecraft will be much shorter, ending early Friday morning. Crew Dragon is expected to return to Earth with a splashdown in the Atlantic Ocean at approximately 8:45 a.m. on Friday, March 8—a little more than six hours after its separation from station.

While Kononenko was focused on the Plasma Kristall-4 experiment, which investigates the liquid phase and flow phenomena of complex plasmas, for this week’s runs, McClain and Saint-Jacques spent most of the day in the Quest airlock. The pair worked on their EMU [Extravehicular Mobility Unit] spacesuits, making sure their suits fit in advance of a series of spacewalks currently slated for late March and early April.

Saint-Jacques also made time in the day to connect with junior high school and college students in Hallifax, Nova Scotia, through a space-to-ground downlink where he shared his perspective of living and working aboard the world’s only microgravity laboratory.
