The Expedition 74 crew explored how living in space affects the brain and blood circulation on Friday to ensure crews stay healthy and ensure long-term mission success. The International Space Station residents also focused on spacewalking tools and science hardware maintenance wrapping up the week.
In late 2025, as comet Lemmon (C/2025 A6) swept past the Sun and brightened in Earth’s night skies, NASA’s Earth-orbiting PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission was watching the comet blaze through its field of view, providing a natural tracer of the Sun’s effects across the inner solar system. Discovered in January […]
The Expedition 74 crew’s research schedule was filled with biomedical duties and artificial intelligence on Thursday to promote crew health and spark innovation on and off the Earth. Spacesuit tailoring and advanced science hardware maintenance rounded out the day for the seven residents aboard the International Space Station.
NASA’s Tropospheric Emissions: Monitoring of Pollution instrument, or TEMPO, is known for measuring trace gases like nitrogen dioxide, ozone, and formaldehyde in the air we breathe. Now TEMPO has a new trick. It can see in the dark. Since launching in 2023, TEMPO data has set a record at the Atmospheric Science Data Center (ASDC) […]
NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission has released processed images of huge eruptions from the Sun, known as coronal mass ejections (CMEs), that occurred from Oct. 21 to Nov. 12. This release marks the first time PUNCH observations can be used to continuously trace solar eruptions from the Sun’s outer atmosphere […]
NASA’s Europa Clipper mission observed the interstellar comet 3I/ATLAS on Nov. 6 from a distance of about 102 million miles (164 million kilometers). Captured over a period of seven hours, the data gathered by the spacecraft’s Europa Ultraviolet Spectrograph (Europa-UVS) instrument will help scientists determine the composition and distribution of elements in the comet’s coma […]
NASA’s Parker Solar Probe completed its 26th close approach to the Sun on Dec. 13, again matching its record distance of 3.8 million miles (6.2 million kilometers) from the solar surface. The spacecraft checked in with flight controllers at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland — where Parker Solar Probe was […]
Exercise and physics research were the top scientific duties aboard the International Space Station on Wednesday advancing human health and industries both on the ground and in space. The Expedition 74 crew members also continued working on spacesuits and practiced an emergency drill.
