Live on NASA+: Three Crewmates Say Farewell, Set to Depart Station
NASA astronaut Jonny Kim and Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky will close the hatch between the Soyuz MS-27 spacecraft and the International Space Station at 5:10 p.m. EST.
Strong Flare Erupts from Sun
The Sun emitted a strong solar flare, peaking at 12:01 a.m. on Dec. 8, 2025. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft […]
From the Archives: NASA’s Goddard Instrument Field Team on the Island of Hawaii
In September 2022, researchers from the NASA Goddard Instrument Field Team (GIFT) were guests on the Island of Hawaii, studying volcanoes and caves.
Crew Swaps Commanders on Sunday as Trio Packs for Departure
Expedition 73 will swap commanders this weekend before three crew members return to Earth on Monday. Expedition 74 officially begins once the home bound trio undocks from the Rassvet module inside the Soyuz MS-27 spacecraft the following day.
Two NASA Scientific Balloon Launches Planned From Antarctica
NASA’s Scientific Balloon Program is back in Antarctica for another long-duration scientific balloon campaign, with two launches planned from the icy surface. Launch operations will begin early December from the agency’s facility located near the U.S. National Science Foundation’s McMurdo Station on the Ross Ice Shelf. To follow the missions, visit NASA’s Columbia Scientific Balloon […]
Station Trio Nears Departure During Busy Day of Blood Research
Three Expedition 73 crewmates will end their stay aboard the International Space Station when they undock Dec. 8 and return to Earth a few hours later. In the meantime, blood research took precedence on Thursday ensuring astronauts stay healthy while living long-term in weightlessness.
NASA’s Hubble Space Telescope Revisits Interstellar Comet
NASA’s Hubble Space Telescope reobserved interstellar comet 3I/ATLAS Nov. 30, with its Wide Field Camera 3 instrument. At the time, the comet was about 178 million miles (286 million kilometers) from Earth. Hubble tracked the comet as it moved across the sky. As a result, background stars appear as streaks of light. Hubble previously observed […]
Biology, Physics Research Progress as Crews Hand Over Responsibilities
Space biology and physics topped the research schedule aboard the International Space Station on Wednesday to improve human health and the space industry. The Expedition 73 residents also helped three new crewmates adapt to orbital life as another trio turns its attention to returning to Earth next week.
NASA’s Psyche Mission Tracks Interstellar Comet 3I/ATLAS
NASA’s Psyche observed interstellar comet 3I/ATLAS over the course of eight hours on Sept. 8 and 9, when the comet was about 33 million miles (53 million kilometers) from the spacecraft. Captured by the mission’s multispectral imager, these observations help astronomers refine the trajectory of 3I/ATLAS. Psyche’s multispectral imager instrument comprises a pair of identical […]
