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.

Crew Dragon has completed all four planned departure burns to begin its journey back to Earth with NASA astronauts Robert Behnken and Douglas Hurley.

With the spacecraft on its path home, the astronauts will settle in for an eight-hour sleep period. While they’re asleep, a six-minute departure phasing burn at 1:48 a.m. Sunday, Aug. 2 will set the Dragon Endeavour on the proper orbital path to a planned splashdown in the Gulf of Mexico off the coast of Pensacola, Florida.

NASA’s live coverage of the crew’s return home to Earth continues through the night.

Behnken and Hurley will begin their last day in space at 7:40 a.m. tomorrow.

The Crew Dragon will separate from its trunk and jettison it at 1:51 p.m., followed five minutes later at 1:56 p.m. with the start of the deorbit burn to commit the spacecraft to a trajectory to splashdown at 2:48 p.m.

Watch live coverage now on NASA TV and the agency’s website as undocking preparations are underway for the return of NASA’s SpaceX Demo-2 test flight with NASA astronauts Robert Behnken and Douglas Hurley from the International Space Station.  

SpaceX and NASA are targeting 7:34 p.m. EDT for Crew Dragon to autonomously undock from the space station, with Behnken and Hurley aboard the spacecraft, and return to Earth. Approximately 19 hours later, after jettisoning its trunk and re-entering Earth’s atmosphere, Crew Dragon will splash down in the Gulf of Mexico off the coast of Florida at 2:48 p.m. EDT on Sunday, August 2. The primary splashdown target is Pensacola. 

Hurley and Behnken arrived at the orbiting laboratory in the Crew Dragon May 31 following a launch from NASA’s Kennedy Space Center in Florida on May 30. This is SpaceX’s final test flight and is providing data on the performance of the Falcon 9 rocket, Crew Dragon spacecraft and ground systems, as well as in-orbit, docking, splashdown, and recovery operations.  

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.

Following a scheduled assessment of weather conditions for splashdown, teams from NASA and SpaceX are proceeding with preparations to bring NASA astronauts Robert Behnken and Douglas Hurley home to Earth aboard the SpaceX Crew Dragon “Endeavour” spacecraft.

Conditions are “Go” at the primary targeted site, off the coast Pensacola, and alternate site off the coast of Panama City in the Gulf of Mexico for splashdown and recovery on Sunday, Aug. 2. Teams will continue to closely monitor Hurricane Isaias and evaluate impacts to the potential splashdown sites.

SpaceX will monitor changes to conditions until 2.5 hours prior to the scheduled undocking, when a determination to proceed with departure will be made. If conditions are marginal and exceed the accepted criteria, a joint recommendation by SpaceX and NASA will be made whether to proceed with undocking at 7:34 p.m. EDT. NASA and SpaceX will make the final decision to proceed after the astronauts are ready inside Crew Dragon just before undocking.

Live coverage of NASA’s SpaceX Demo-2 return will begin at 5:15 p.m. and continue through the targeted splashdown at 2:41 p.m. on Sunday, the first return of a commercially built and operated American spacecraft carrying astronauts from the space station. It will wrap up NASA’s SpaceX Demo-2 test flight after more than two months at the International Space Station.

Hurley and Behnken arrived at the orbiting laboratory in the Crew Dragon May 31 following a launch from NASA’s Kennedy Space Center in Florida on May 30. This is SpaceX’s final test flight and is providing data on the performance of the Falcon 9 rocket, Crew Dragon spacecraft and ground systems, as well as in-orbit, docking, splashdown, and recovery operations.

Teams from NASA and SpaceX are proceeding with preparations to bring NASA astronauts Robert Behnken and Douglas Hurley home from the International Space Station to Earth with a splashdown on Sunday, Aug. 2, off the Florida coast aboard the SpaceX Crew Dragon “Endeavour” spacecraft.

Watch the crew farewell ceremony on YouTube.

Return conditions remained “Go” at several of the needed target locations for splashdown and recovery after teams received a weather briefing Friday evening from the U.S. Air Force 45th Weather Squadron. NASA and SpaceX will make a decision on a primary splashdown target approximately 6 hours before undocking.

NASA and SpaceX are targeting 7:34 p.m. EDT Saturday, Aug. 1, for undocking of the Dragon “Endeavour” spacecraft from the space station and 2:42 p.m. Sunday, Aug. 2, for splashdown, which will be the first return of a commercially built and operated American spacecraft carrying astronauts from the space station.

Teams continue to closely monitor Hurricane Isaias and evaluate impacts to the landing sites in the Gulf of Mexico along the Florida Panhandle. Teams have several weather decision milestones ahead of and after undocking to adjust the splashdown location and time based on the forecasted conditions for recovery.

NASA’s SpaceX Demo-2 return coverage is as follows (all times Eastern):

Saturday, Aug. 1

• 5:15 p.m. – NASA TV undocking coverage begins for the 7:34 p.m. undocking (NASA Television will have continuous coverage from undocking to splashdown)

Sunday, Aug. 2

• 2:42 p.m. – Splashdown
• 5 p.m. – Administrator post-splashdown news conference at Johnson, with the following representatives:
  • NASA Administrator Jim Bridenstine
  • Commercial Crew Program representative
  • International Space Station representative
  • Gwynne Shotwell, president and chief operating officer, SpaceX
  • NASA Astronaut Office representative

Tuesday, Aug. 4 

• 4:30 p.m. – Demo-2 Crew News Conference from the Johnson Space Center, with the following participants
  • NASA astronaut Bob Behnken
  • NASA astronaut Doug Hurley

Behnken and Hurley 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 63 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.

These activities are a part of NASA’s Commercial Crew Program, which has been working with the U.S. aerospace industry to launch astronauts on American rockets and spacecraft from American soil the International Space Station for the first time since 2011. This is SpaceX’s final test flight and is providing data on the performance of the Falcon 9 rocket, Crew Dragon spacecraft and ground systems, as well as in-orbit, docking, splashdown and recovery operations.

The test flight also is helping NASA certify SpaceX’s crew transportation system for regular flights carrying astronauts to and from the space station. SpaceX is readying the hardware for the first rotational mission, which would occur following NASA certification.

The goal of NASA’s Commercial Crew Program is safe, reliable and cost-effective transportation to and from the International Space Station. This could allow for additional research time and increase the opportunity for discovery aboard humanity’s testbed for exploration, including helping us prepare for human exploration of the Moon and Mars.
