In this May 1, 2025, photo taken by fellow NASA astronaut Nichole Ayers, Anne McClain works near one of the International Space Station’s main solar arrays during a spacewalk. During the May 1 spacewalk – McClain’s third and Ayers’ first – the astronaut pair relocated a space station communications antenna and completed the initial mounting […]...
Lee esta nota de prensa en español aquí. For the first time, astronomers have probed the physical environment of repeating X-ray outbursts near monster black holes thanks to data from NASA’s NICER (Neutron star Interior Composition Explorer) and other missions. Scientists have only recently encountered this class of X-ray flares, called QPEs, or quasi-periodic eruptions. […]...
1. Why is the International Space Station up there? The International Space Station is a convergence of science, technology, and human innovation that enables research not possible on Earth for the benefit of humanity. For more than 25 years, NASA has supported a continuous U.S. human presence aboard the station, through which astronauts have learned […]...
Future space missions could use quantum technologies to help us understand the physical laws that govern the universe, explore the composition of other planets and their moons, gain insights into unexplained cosmological phenomena, or monitor ice sheet thickness and the amount of water in underground aquafers on Earth. NASA’s Cold Atom Lab (CAL), a first-of-its-kind […]...
The Soyuz MS-26 spacecraft is pictured backing away from the International Space Station shortly after undocking on April 19, 2025. Three hours later, the spacecraft landed in Kazakhstan, returning astronaut Don Pettit and cosmonauts Alexey Ovchinin and Ivan Vagner to Earth. While aboard the International Space Station, Pettit conducted hundreds of hours of scientific investigations, […]...
Inside a laboratory in the Space Systems Processing Facility at NASA’s Kennedy Space Center in Florida, a payload implementation team member harvests ‘Outredgeous’ romaine lettuce growing in the Advanced Plant Habitat ground unit on Thursday, April 24, 2025. The harvest is part of the ground control work supporting Plant Habitat-07, which launched to the International […]...
NASA astronaut Nichole Ayers and JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi will answer prerecorded questions about science, technology, engineering, and mathematics from students in Mansfield, Texas, while aboard the International Space Station. The 20-minute space-to-Earth call will take place at 10:40 a.m. EDT on Monday, May 5, and can be watched on the […]...
Crew members are kicking off operations for several biological experiments that recently launched to the International Space Station aboard NASA’s 32nd SpaceX commercial resupply services mission. These include examining how microgravity affects production of protein by microalgae, testing a microscope to capture microbial activity, and studying genetic activity in biofilms. Microalgae in microgravity This ice […]...
Science in Space April 2025 Humans have always been explorers, venturing by land and sea into unknown and uncharted places on Earth and, more recently, in space. Early adventurers often navigated by the Sun and stars, creating maps that made it easier for others to follow. Today, travelers on Earth have sophisticated technology to guide […]...
Students from Santa Monica, California, will connect with NASA astronaut Jonny Kim as he answers prerecorded science, technology, engineering, and mathematics-related questions aboard the International Space Station. Watch the 20-minute space-to-Earth call at 12:10 p.m. EDT on Tuesday, April 29, on the NASA STEM YouTube Channel. Media interested in covering the event must RSVP by […]...
