Starliner was raised and carefully placed onto the rocket and now is fully assembled and ready for an integrated systems test, a tip-to-tail electrical check of the 172-foot-tall Atlas V and Starliner stack.

OFT-2 is scheduled to launch Thursday, May 19, to demonstrate the system’s human transportation capabilities.

About 24 hours after launch, Starliner will rendezvous and dock to the space station and then return to Earth five to 10 days later. The test is the last flight before the Starliner system launches American astronauts on the Crew Flight Test (CFT) to the microgravity laboratory – the spacecraft’s first flight test with crew on board. Potential launch windows for CFT are under review and will be determined after a safe and successful OFT-2.

NASA astronaut Tom Marshburn handed over command of the International Space Station to Russian cosmonaut Oleg Artemyev in a traditional Change of Command ceremony which began at 2:35 p.m. EDT today. Artemyev, a veteran of three spaceflights to the space station, will lead the Expedition 67 crew until the end of summer.

Marshburn and his Crew-3 crewmates Kayla Barron, Raja Chari, and ESA astronaut Matthias Maurer have been living aboard the orbital lab since November 11, 2021, and are set to depart tonight. Hatch closure is set for 11:20 p.m. EDT, with undocking following at 1:05 a.m. EDT. The commercial crew quartet is due to splashdown off the coast of Florida  at 12:43 a.m. EDT on Friday, May 6. Watch live on NASA TV, the agency’s website, and the app.

The Crew-3 astronauts worked on final Dragon cargo operations and configuring Dragon for departure, final egress, and hatch closure, as well as transferring emergency hardware from Dragon to the space station prior to departure. The Endurance crew closed out research operations which included transferring and packing frozen samples and ice bricks from the Minus Eighty (Degrees Celsius) Laboratory Freezer for ISS (MELFI) into coldbags in preparation for the return to Earth. MELFI provides the space station storage and fast-freezing of life science and biological samples. The Crew-3 astronauts also removed and stowed their Actiwatches, small, lightweight, wrist-worn devices that simultaneously detect body movement and light intensity. They are used to evaluate sleep-wake adaptation and circadian cycle and determine if space travel has an impact on the sleep-wake patterns of crewmembers.

The station’s four newest astronauts, Kjell Lindgren, Bob Hines, Jessica Watkins, and Samantha Cristoforetti, had a light duty day performing some life science, lab maintenance, and inventory tasks. The foursome and their three Russian crewmates are due to have an off-duty day following the departure of the SpaceX Crew-3 mission.

In the station’s Russian segment, Artemyev and Flight Engineers Sergey Korsakov and Denis Matveev performed monthly maintenance checks on laptops and video equipment, as well as physical training, and a robotic piloting experiment.

NASA astronauts Kjell Lindgren, Robert Hines, and Jessica Watkins, and ESA (European Space Agency) astronaut Samantha Cristoforetti are on their way to the International Space Station, following the picture-perfect launch of the agency’s SpaceX Crew-4 mission. SpaceX’s Crew Dragon spacecraft, named Freedom by the crew, launched atop the company’s Falcon 9 rocket from Kennedy Space Center’s Launch Complex 39A in Florida at 3:52 a.m. EDT.

“This is our fourth crew rotation flight – it’s kind of hard to believe,” said Steve Stich, manager, Commercial Crew Program, NASA’s Johnson Space Center in Houston. “It seems like Demo-2 was just yesterday, and it’s exciting to be here. We had a really clean countdown today – the Falcon 9 rocket did great; the Dragon vehicle did great. It was great to see the crew get in. You could tell they were excited to start their flight off.”

Upon their arrival at the space station, the Crew-4 astronauts will be greeted by NASA astronauts of the Expedition 67 crew already on board. During their six-month stay aboard the microgravity laboratory, Lindgren, Hines, Watkins, and Cristoforetti will join the Expedition 67 crew in conducting a number of science and research investigations.

The Crew-4 astronauts will conduct new and exciting scientific research in areas such as materials science, health technologies, and plant science to prepare for human exploration beyond low-Earth orbit and benefit life on Earth. Experiments will include studies on the aging of immune systems, organic material concrete alternatives, and cardiorespiratory effects during and after long-duration exposure to microgravity. These are just some of the more than 200 science experiments and technology demonstrations that will take place during their mission.

Launching alongside the crew in the Dragon capsule is an investigation that seeks to restore meaningful vision to people suffering from retinal degenerative diseases like retinitis pigmentosa and macular degeneration. The Protein-Based Artificial Retina Manufacturing experiment tests the manufacturing of artificial retinas or retinal implants in microgravity, where it is expected their production could be optimized.

Also traveling to space aboard the Crew Dragon are Smart-Tex shirts as part of the German Space Agency (DLR) investigation called Wireless Compose-2. The shirts are fitted with sensors, wiring, and a communications module to wirelessly transmit data to a base station. The shirt is designed to monitor cardiovascular activity like relative blood pressure and can provide details about heart contraction rate and valve opening and closing times – something normally accessible only through sonography or CT scans. These kinds of wearable technologies could be used to monitor health throughout a long-duration space exploration mission and could lead to a more flexible implementation of this technology in health monitoring equipment on Earth.

Crew-4 is NASA’s fourth crew rotation mission with SpaceX for the agency’s Commercial Crew Program. Lindgren and Cristoforetti have previously traveled to the International Space Station, while it will be the first trip for Hines and Watkins. Crew-4 astronauts are slated to arrive at the space station today, April 27, with docking targeted for 8:15 p.m. EDT. Following docking and hatch opening, a welcoming ceremony is planned for 2:40 a.m. EDT.

Coverage of Crew-4’s arrival to the station will air live on NASA Television and the agency’s website, beginning with docking at 8:15 p.m. EDT.
