NASA’s SpaceX Crew-10 to Discuss Station Mission, Upcoming Return

Media are invited to hear from NASA’s SpaceX Crew-10 during a news conference beginning at 10:40 a.m. EDT, Friday, July 25, from the International Space Station.

NASA astronauts Anne McClain and Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov will discuss their upcoming return to Earth on the agency’s YouTube channel.

Media interested in participating must contact the newsroom at NASA’s Johnson Space Center in Houston no later than 5 p.m., Thursday, July 24, at 281-483-5111 or jsccommu@mail.nasa.gov. To ask questions, media must dial into the news conference no later than 10 minutes prior to the start of the call. A copy of NASA’s media accreditation policy is online.

Crew-10 joined the Expedition 72 crew when arriving to the station in March. Throughout Expedition 72 and into Expedition 73, the crew aboard the space station contributed to hundreds of experiments, including testing expanded capabilities of existing hardware for pharmaceutical production in space, investigating how cells sense gravity, which is an important aspect of space biology, and examining the effects of microgravity on protein yields in microalgae, a potential source for life support, fuel, and food on long-duration missions.

The crew will depart the space station after the arrival of Crew-11 and a handover period. Ahead of Crew-10’s return, mission teams will review weather conditions at the splashdown sites off the coast of California prior to departure from station.

The mission is part of NASA’s Commercial Crew Program, which provides reliable access to space, maximizing the use of the station for research and development and supporting future missions beyond low Earth orbit by partnering with private companies to transport astronauts to and from the space station.

These Massive Runaway Stars Were Birthed in a Chaotic Cluster

Universe Today - Mon, 07/21/2025 - 2:29pm

Mysteries abound in space. In the Tarantula Nebula, which lies in the Large Magellanic Cloud, astronomers used simulations to reconstruct how three stars were ejected from the star cluster R136, about 60,000 years ago. The analysis, published in Physical Review Letters, reveals that five stars were involved, an unexpected result.

The Most Massive Black Hole Merger Ever

Universe Today - Mon, 07/21/2025 - 2:29pm

Astronomers using the LIGO-Virgo-KAGRA gravitational wave detectors announced the most massive black hole merger ever seen. Two black holes crashed together, producing a final black hole with approximately 225 times the mass of the Sun. Designated GW231123, it was detected during the 2023 observing run, and appears to be from the collision of 100- and 140-stellar-mass black holes. Black holes this massive are hard to get through standard stellar evolution, but could be the results of previous mergers.
