Commander Chris Cassidy switched off communications gear today used to send commands to Japan’s H-II Transfer Vehicle-9 (HTV-9) after its departure on Tuesday. The HTV-9 will orbit Earth until Thursday morning when it descends into the atmosphere for a fiery, but safe demise over the South Pacific.
The NASA commander spent the rest of the day working on orbital plumbing and life support gear. Cassidy removed and replaced the Waste and Hygiene Compartment’s recycle tank located in the Tranquility module. He also inspected out gear that analyzes organic compounds in the station’s air.
Space traffic will be clear at the space station for the rest of August and into September. The mission pace will pick back up in October with a U.S. Cygnus cargo ship from Northrop Grumman, the Expedition 64 crew and the SpaceX Crew-1 mission all to set to arrive within a period of three weeks.
Commander Chris Cassidy of NASA will be at the robotics workstation on Tuesday and direct the 57.7-foot-long Canadarm2 to release the HTV-9 from its grip at 1:35 p.m. EDT. Roscosmos Flight Engineer Ivan Vagner will back up Cassidy and monitor the release of the HTV-9 as it completes its 85-day cargo mission. NASA TV will cover the activities live starting at 1:15 p.m.
The HTV-9 will spend two more days orbiting Earth before a fiery, atmospheric demise over the South Pacific. JAXA (Japan Aerospace Exploration Agency) is developing an upgraded fleet of HTV-X space station suppliers, replacing the HTV series of spaceships, targeted for their first launch in 2022.
The Expedition 63 and 64 crews are due to trade places at the orbiting lab beginning in mid-October. The Soyuz MS-17 crew ship is slated to blast off from the Baikonur Cosmodrome in Kazakhstan on Oct. 14 and dock to the station’s Rassvet module. NASA astronaut Kate Rubins with Roscosmos cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov will then begin a six-month space research mission.
One week later on Oct. 21, Cassidy will wrap up his mission with crewmates Vagner and Russian Flight Engineer Anatoly Ivanishin. The trio will enter the Soyuz MS-16 crew ship, undock from the Poisk module and parachute to a landing in Kazakhstan ending a 195-day expedition in space.
NASA and SpaceX have announced the launch of the SpaceX Crew-1 mission to the station for no earlier than Oct. 23. Mike Hopkins of NASA will command the first operational flight of the Crew Dragon spacecraft piloted by first-time NASA astronaut Victor Glover. They will be joined by Mission Specialists Shannon Walker of NASA and Soichi Noguchi of JAXA, both previous station residents.
SpaceX has completed its demonstration mission phase and has already booked two operational Crew Dragon missions. Crew-1 is planned for later this year and Crew-2 is targeted for Spring 2021. Both commercial crew missions will launch four astronauts each to the space station to continue microgravity science.
Russia will launch three Expedition 64 crew members to the station one week before the Expedition 63 crew returns to Earth in October. NASA astronaut Kate Rubins and cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov will liftoff inside the Soyuz MS-17 crew ship to begin a six-month mission aboard the orbital lab.
Two NASA astronauts, Robert Behnken and Douglas Hurley, splashed down safely in the SpaceX Crew Dragon “Endeavour” in the Gulf of Mexico off the coast of Pensacola, Florida, at 2:48 p.m. EDT. It is the first time a commercially built and operated American crew spacecraft has returned from the International Space Station to complete a test flight, beginning a new era in human spaceflight.
Teams on the Go Navigator recovery ship, including two fast boats, now are in the process of securing Crew Dragon and ensuring the spacecraft is safed for the recovery effort. As the fast boat teams complete their work, the recovery ship will move into position to hoist Crew Dragon onto the main deck of Go Navigator with Behnken and Hurley inside. Once on the main deck, the crew will be taken out of the spacecraft and receive medical checks before a helicopter ride to Pensacola to board a plane for Houston.
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.
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 about 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 will help 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 that will occur following NASA certification, which is expected to take about six weeks.
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.
Watch NASA’s live coverage as NASA astronauts Robert Behnken and Douglas Hurley inside the SpaceX Crew Dragon “Endeavour” spacecraft are making their final orbit of Earth before splashing down in the Gulf of Mexico at 2:48 p.m. EDT. Weather conditions remain within the splashdown weather criteria and are “Go” at the primary targeted site off the coast of Pensacola, Florida.
Here are the upcoming milestones (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.
NASA astronauts Robert Behnken and Douglas Hurley are just hours away from splashdown in the Gulf of Mexico off the coast of Florida. Splashdown remains scheduled for 2:48 p.m. EDT following a nearly two-month test flight of the SpaceX Crew Dragon spacecraft as part of NASA’s Commercial Crew Program.
Pensacola, Florida remains the prime location with Go Navigator as the recovery vessel. The recovery boat departed its port at 9:20 a.m. to stage for recovery operations in the Gulf of Mexico. Go Navigator is operating with a fully functioning generator and is ready to support splashdown operations this afternoon. Earlier this morning, a backup generator failed on the recovery ship prior to leaving port, but that is not considered an impact for normal recovery operations. The recovery vessel still has full capability to safely recover the spacecraft and crew.
Return conditions remain “Go” at the primary and alternate targeted sites.

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.
The SpaceX Crew Dragon “Endeavour” spacecraft with NASA astronauts Robert Behnken and Douglas Hurley inside undocked from the forward end of the International Space Station’s Harmony module at 7:35 p.m. EDT to complete a two-month mission.
Two very small engine burns separated Crew Dragon from the station, and the spacecraft is slowly maneuvering away from the orbital laboratory into an orbital track that will return the astronaut crew and its cargo safely to Earth.
Once flying free, Dragon Endeavour will autonomously execute four departure burns to move the spaceship away from the space station and begin the flight home.
The return timeline with approximate times in EDT is:
7:35 p.m. Departure burn 0
7:40 p.m. Departure burn 1
8:27 p.m. Departure burn 2
9:14 p.m. Departure burn 3
1:51 p.m. Trunk jettison
1:56 p.m. Deorbit burn
2:48 p.m. Crew Dragon splashdown
NASA will continue to provide live coverage until astronaut Behnken and Hurley splashdown off the coast of Florida and are recovered from the Gulf of Mexico.

NASA astronauts Robert Behnken and Douglas Hurley are now seated inside SpaceX’s Crew Dragon “Endeavour” spacecraft as fellow Expedition 63 astronauts Commander Chris Cassidy of NASA and Roscosmos cosmonauts Anatoly Ivanishin and Ivan Vagner closed the hatch between Crew Dragon and the orbital laboratory at 5:37 p.m. EDT.
Teams will conduct standard leak checks and depressurization of the space between the spacecraft and the station, called the vestibule, in preparation for Dragon Endeavour’s undocking and return to Earth. Undocking is scheduled for 7:34 p.m. EDT. After hooks holding Crew Dragon in place retract, two very small engine burns will fire to separate the spacecraft from the 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.
