The MD-11’s high landing speed is unusual among modern widebody airliners and it makes the aircraft more difficult to land.
Massive Stars Make Their Mark in Hubble Image
This NASA/ESA Hubble Space Telescope image features a glittering blue dwarf galaxy called Markarian 178 (Mrk 178). The galaxy, which is substantially smaller than our own Milky Way, lies 13 million light-years away in the constellation Ursa Major (the Great Bear). Mrk 178 is one of more than 1,500 Markarian galaxies. These galaxies get their name from […]
NASA’s Two-in-One Satellite Propulsion Demo Begins In-Space Test
NASA is working with commercial partners to create high-performing, reliable propulsion systems that will help small spacecraft safely maneuver in orbit, reach intended destinations across the solar system, and accomplish mission operations. Two new micropropulsion technologies are being tested in space onboard a CubeSat called DUPLEX (Dual Propulsion Experiment) that deployed into low Earth orbit […]
NASA’s Push Toward Commercial Space Communications Gains Momentum
NASA’s commercial partners are actively demonstrating next-generation satellite relay capabilities for spaceflight missions, marking a significant step toward retiring the agency’s Tracking and Data Relay Satellite (TDRS) system and adopting commercial services. The demonstrations – ranging from real-time spacecraft tracking during launch to transmitting mission commands and scientific data – are part of NASA’s Communications […]
NASA Study Suggests Saturn’s Moon Titan May Not Have Global Ocean
A key discovery from NASA’s Cassini mission in 2008 was that Saturn’s largest moon Titan may have a vast water ocean below its hydrocarbon-rich surface. But reanalysis of mission data suggests a more complicated picture: Titan’s interior is more likely composed of ice, with layers of slush and small pockets of warm water that form […]
