Astronauts Wake Up, Preps Crew Dragon For Splashdown Today

SpaceX’s first Crew Dragon parachutes to a splashdown in the Atlantic Ocean during the uncrewed Demo-1 mission on March 8, 2019.

NASA astronauts Robert Behnken and Douglas Hurley are beginning their final day in orbit inside the Crew Dragon “Endeavour” spacecraft ahead of splashdown in the Gulf of Mexico at 2:48 p.m. EDT this afternoon.

NASA’s live coverage of the return continues.

To wake them, Mission Control Hawthorne played the dads an audio message from  their sons.

Conditions remain “Go” at the primary targeted site, off the coast of Pensacola, and alternate site off the coast of Panama City in the Gulf of Mexico for splashdown and recovery.

Here’s the timeline for return activities (all times Eastern):

1:51 p.m. – Crew Dragon performs claw separation. The claw is located on Crew Dragon’s trunk, connecting thermal control, power, and avionics system components located on the trunk to the capsule.

  • 1:51 p.m. – Trunk separation
  • 1:56 p.m. – Deorbit burn begins
  • 2:08 p.m. – Deorbit burn complete
  • 2:11 p.m. – Nosecone deploys
  • 2:32 p.m. – Crew Dragon maneuvers to attitude for re-entry
  • 2:44 p.m. – Drogue parachutes deploy at about 18,000 feet in altitude while Crew Dragon is moving approximately 350 miles per hour.
  • 2:45 p.m. – Main parachutes deploy at about 6,000 feet in altitude while Crew Dragon is moving approximately 119 miles per hour.
  • 2:48 p.m. – Splashdown

Crew Dragon autonomously undocked from the International Space Station’s Harmony module at 7:35 p.m. Saturday, two very small engine burns separating Crew Dragon from the station, and the spacecraft slowly maneuvered away from the orbital laboratory. Once flying free, Dragon Endeavour autonomously executed four departure burns that moved the spaceship away from the space station and the crew began the flight home. A phasing burn overnight put it on its path toward Pensacola.

The duo arrived at the orbiting laboratory on May 31, following a successful launch on May 30 on a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. During their 62 days aboard station, Behnken and Hurley contributed more than 100 hours of time to supporting the orbiting laboratory’s investigations, participated in public engagement events, and supported four spacewalks with Behnken and Cassidy to install new batteries in the station’s power grid and upgrade other station hardware.

Station Wraps Busy Week Before Cygnus Cargo Mission Launches

Image
This high exposure photograph from the International Space Station shows Earth’s atmospheric glow and a starry sky as the orbital complex soared above the Pacific Ocean. The Expedition 70 crew is looking ahead to the arrival of a U.S. cargo craft due to arrive at the International Space Station next week. Meanwhile, the Axiom Space 3 (Ax-3) crew finished its first week in orbit with a busy schedule of research, education, and media activities. Northrop Grumman’s Cygnus cargo craft will take its first ride atop a SpaceX Falcon 9 rocket when it lifts off at 12:29 p.m. EST on Monday from Kennedy Space Center in Florida. The private space freighter will be carrying over 8,200 pounds of science experiments, crew supplies, and lab hardware to the orbiting outpost. NASA Flight Engineer Jasmin Moghbeli is due to capture Cygnus with the Canadarm 2 robotic arm at 3:35 a.m. on Wednesday. She will be on duty that morning along with fellow NASA astronaut Loral O’Hara who will monitor Cygn...

NASA and Sierra Space are making progress on the first flight of the company’s Dream Chaser spacecraft to the International Space Station. The uncrewed cargo spaceplane is planned to launch its demonstration mission in 2024 to the orbital complex as part of NASA’s commercial resupply services. Credit: Sierra Space/Shay Saldana NASA and Sierra Space are preparing for the first flight of the company’s Dream Chaser spacecraft to the International Space Station. Dream Chaser and its companion cargo module, called Shooting Star, arrived at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, for environmental testing, scheduled to start in mid-December, ahead of its first flight, scheduled for the first half of 2024. The Neil Armstrong Test Facility, part of NASA’s Glenn Research Center in Cleveland, is home to multiple test facilities, including the Space Environments Complex and the In-Space Propulsion Facility, both stops for Dream Chaser. The complex is home to the Mechanical Vib...

Crew Dragon Suit Checks as Station Begins Orbital Reboosts

Image
This long-exposure photograph from the space station reveals the Milky Way glittering above a bright but exaggerated atmospheric glow blanketing the Earth’s horizon. The Expedition 63 crew checked out SpaceX Crew Dragon suits today and stayed busy with a full slate of space research. The International Space Station also completed the first of three orbital reboosts to get ready for the next crew mission in October. Flight Engineers Doug Hurley and Bob Behnken inspected the suits they will wear when they return to Earth aboard the Crew Dragon spaceship. The duo tried on their suits for a fit check and ensured the components are in good condition. They are scheduled to depart the station on Saturday and splashdown the following day. NASA TV will cover all the departure activities live. The homebound-duo started the day replacing environmental control system (ECS) hardware aboard the orbiting lab. That work required temporarily removing a plant habitat from the Unity module to...
