NASA coverage now is underway for the launch of a crewed Soyuz spacecraft to the International Space Station with NASA astronaut Tracy C. Dyson, Roscosmos cosmonaut Oleg Novitskiy, and spaceflight participant Marina Vasilevskaya of Belarus.
The Soyuz MS-25 spacecraft will launch from the Baikonur Cosmodrome in Kazakhstan at 8:36 a.m. EDT (5:36 p.m. Baikonur time). Coverage of launch will air live on NASA+, NASA Television, the NASA app, YouTube, and the agency’s website. Learn how to stream NASA TV through a variety of platforms including social media.
The Soyuz will dock to the space station’s Prichal module at 11:09 a.m. Monday, March 25. Shortly after, hatches between the Soyuz and the station will open and the crew members will greet each other.
Docking coverage will begin at 10:15 a.m. March 25 on NASA+, NASA Television, the NASA app, YouTube, and the agency’s website.
Once aboard station, the trio will join Expedition 70 crew members including NASA astronauts Loral O’Hara, Matthew Dominick, Mike Barratt, and Jeanette Epps, as well as Roscosmos cosmonauts Oleg Kononenko, Nikolai Chub, and Alexander Grebenkin.
Dyson will spend six months aboard the station as an Expedition 70 and 71 flight engineer, returning to Earth in September with Oleg Kononenko and Nikolai Chub of Roscosmos, who will complete a year-long mission on the laboratory.
Novitskiy and Vasilevskaya will be aboard the station for 12 days, providing the ride home for O’Hara on Saturday, April 6, aboard Soyuz MS-24 for a parachute-assisted landing on steppe of Kazakhstan. O’Hara will have spent 204 days in space when she returns.
NASA coverage is as follows (all times Eastern and are subject to change based on real-time operations):
Saturday, March 23
8:36 a.m. – Launch
Monday, March 25
10:15 a.m. – Rendezvous and docking coverage begins

Dragon Spacecraft Docks to Station With New Science, Supplies

While the International Space Station was traveling more than 262 miles over the South Atlantic Ocean, a SpaceX Dragon cargo spacecraft autonomously docked to station’s Harmony module at 7:19 a.m. EDT, with NASA astronauts Loral O’Hara and Michael Barratt monitoring operations from the station.
The Dragon launched on SpaceX’s 30th contracted commercial resupply mission for NASA at 4:55 p.m. EDT, March 21, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. After Dragon spends about one month attached to the space station, the spacecraft will return to Earth with cargo and research.
Among the science experiments Dragon is delivering to the space station are:
Monitoring Sea Ice Thickness and Wave Height
(Nanoracks-Killick-1) is a CubeSat that measures sea ice parameters using Global Navigation Satellite System (GNSS) reflectometry or reflected signals. This monitoring system could contribute to a better understanding of important ocean phenomena and improved weather and climate models.
New Sensors for ASTROBEE
The Multi-resolution Scanner (MRS) Payload for the Astrobee (Multi-Resolution Scanning) tests a new set of sensors to support automated 3D sensing, mapping, and situational awareness functions. These systems could support future Gateway and Lunar surface missions by providing automated defect detection, automated and remote maintenance, and autonomous vehicle operations.
Improving Efficiency of Quantum-Dot Solar Cells
The Nano Particle Haloing Suspension payload tests the controlled assembly of nanoparticles in a liquid solution. A process called nanoparticle haloing uses charged nanoparticles to enable precise particle arrangements that improve the efficiency of quantum-dot synthesized solar cells. Conducting these processes in microgravity provides insight into the relationship between shape, charge, concentration, and interaction of particles.
Observing Photosynthesis in Space
Advanced Plant Experiment-09 (APEX-09), also known as C4 Photosynthesis in Space, observes carbon dioxide capture and mechanisms in two types of grasses. Researchers hope to learn more about photosynthesis and plant metabolism changes overall in space. Knowledge gained could support development of bioregenerative life support systems on future missions.
These are just a few of the hundreds of investigations currently being conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Advances in these areas will help keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration beyond low-Earth orbit to the Moon through NASA’s Artemis missions and eventually Mars.
NASA Astronaut Tracy Dyson, Crewmates Safely En Route to Space Station
The Soyuz rocket launches to the International Space Station with Expedition 71 NASA astronaut Tracy Dyson, Roscosmos cosmonaut Oleg Novitskiy, and Belarus spaceflight participant Marina Vasilevskaya, onboard, Saturday, March 23, 2024, at the Baikonur Cosmodrome in Kazakhstan.

Three crew members including NASA astronaut Tracy C. Dyson successfully launched at 8:36 a.m. EDT Saturday from the Baikonur Cosmodrome in Kazakhstan to the International Space Station.
Dyson, along with her crewmates Roscosmos cosmonaut Oleg Novitskiy and spaceflight participant Marina Vasilevskaya of Belarus, will dock to the space station’s Prichal module about 11:09 a.m. on Monday, March 25, on the Soyuz MS-25 spacecraft.
Docking coverage will begin at 10:15 a.m. on NASA+, NASA Television, the NASA app, YouTube, and the agency’swebsite. NASA also will air coverage, starting at 1:15 p.m., of the crew welcome ceremony on NASA+ once they are aboard the orbital outpost. Learn how to stream NASA TV through a variety of platforms including social media.
When the hatches between the station and the Soyuz open about 1:40 p.m., the new crew members will join NASA astronauts Loral O’Hara, Matthew Dominick, Mike Barratt, and Jeanette Epps, as well as Roscosmos cosmonauts Oleg Kononenko, Nikolai Chub, and Alexander Grebenkin, already living and working aboard the space station.
Novitskiy and Vasilevskaya will be aboard the station for 12 days, before providing the ride home for O’Hara on Saturday, April 6, aboard Soyuz MS-24 for a parachute-assisted landing on steppe of Kazakhstan.
Dyson will spend six months aboard the station as an Expedition 70 and 71 flight engineer, returning to Earth in September with Oleg Kononenko and Nikolai Chub of Roscosmos, who will complete a year-long mission on the laboratory.
This will be the third spaceflight for Dyson, the fourth for Novitskiy, and the first for Vasilevskaya.
Dragon Cargo Spacecraft Arriving to Station Soon Live on NASA TV
The SpaceX Dragon resupply spacecraft, carrying over 5,800 pounds of cargo, approaches the space station above the south Atlantic Ocean on July 16, 2022.
A SpaceX Dragon is on track to arrive at the International Space Station today, Saturday, March 23, with an expected docking of the cargo spacecraft about 7:16 a.m. EDT. Live coverage is underway on NASA+, NASA Television, the NASA app, and the agency’s website.
When it arrives to the space station, Dragon will dock to the station’s Harmony module. NASA astronauts Loral O’Hara and Michael Barratt will monitor the arrival of the spacecraft.
Dragon successfully launched on a SpaceX Falcon 9 rocket at 4:55 p.m. EDT, March 21, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida, carrying more than 6,000 pounds of research, hardware, and supplies to the International Space Station.
