Before scientists can use those satellite imagery for research, the data must be carefully calibrated to ensure measurements are accurate and consistent over time. Julia Barsi, NASA calibration scientist, explains.
Space nuclear power and propulsion engineering could play a key role in sending robots and humans to deep space, enabling faster and farther journeys.
The “test like you fly” approach is an engineering philosophy that means testing hardware, software, and flight operations as close to reality as possible. Erika Alvarez, deputy director of NASA's Space Systems Departmen
So-called “soft skills” like good teamwork and communication can become just as valuable as technical skills to advance exploration.
NASA pilots play a critical role in launch and recovery operations. Shannon Gregory, chief of flight operations at Kennedy Space Center, shares how his team supports crewed launches from the air, capturing real-time imag
Studying planets in other solar systems isn’t easy, especially when their host stars keep stealing the spotlight. NASA’s Pandora mission will cut through the noise, revealing what the atmospheres of these distant worlds
For any crew returning to Earth from space, the journey home includes a carefully choreographed recovery effort to bring them safely back on dry land after splashing down in the ocean. Christine St. Germain, NASA recover
NASA's Dragonfly spacecraft, a rotorcraft the size of a small car, is set to explore Titan, Saturn's largest moon. Rich in organic compounds, Titan offers a rare window into the kinds of chemical conditions that may have
Nujoud Merancy, NASA's deputy associate administrator for the Strategy and Architecture Office, talks about how NASA is developing the roadmap for Artemis missions to the Moon and beyond.
From her experience working with the Commercial Crew Program, which sends astronauts to the International Space Station aboard commercial spacecraft, to the Artemis missions to the Moon, aerospace engineer Jennifer Lu sh
Currently, flying faster than the speed of sound over land is prohibited for commercial flights because it creates disruptive sonic booms. NASA's experimental X-59 plane will research how to turn those booms into "sonic
A solar sail uses light particles from the Sun to move through space without needing a single drop of fuel. NASA is demonstrating the lightweight technology that could open doors to low-cost missions to deep space.
Dr. Jennifer Edmunson explains what it takes to simulate Moon and Mars dust on Earth, and lessons learned from preparing to build habitats on other worlds.
There’s a program at NASA that taps into the power of the public to solve some of the toughest problems in space exploration. It’s called Centennial Challenges, a prize competition that has awarded more than $24 million
On September 17, 2025, NASA announced that the number of exoplanets, planets outside our solar system, tracked by NASA has reached 6,000. In the three decades since the groundbreaking detection of exoplanet 51 Pegasi b,
A steel vacuum chamber 50 stories deep at NASA’s Glenn Research Center lets researchers simulate near-weightlessness by letting test hardware freefall for 5.18 seconds.
From black holes to star clusters, scientists are turning space data into sound with a process called sonification. Dr. Kimberly Arcand, visual scientist with the Harvard-Smithsonian Center for Astrophysics, joins us to
StarBurst, a satellite the size of a washing machine, aims to detect the initial blast of gamma-rays, the most powerful bursts of energy in the universe. These huge explosions can occur when dense neutron stars collide,
The Hubble Space Telescope has changed humanity’s understanding of the universe. Now in orbit for 35 years, it remains a remarkable feat of engineering.
Fighting wildland fires by air at night is especially hazardous. NASA’s ACERO Project aims to make firefighting safer, day or night, with drones and smarter airspace management.
