It can happen in a flash — airborne science, that is. Two hundred microseconds, to be exact. With lasers shot from the belly of a King Air B200 aircraft. That’s right, scientists are shooting lasers at atmospheric gases — not to zap them out of existence, but to measure them.
On the outskirts of our galaxy, a cosmic tug-of-war is unfolding—and only NASA’s Hubble Space Telescope can see who’s winning. The players are two dwarf galaxies, the Large Magellanic Cloud and the Small Magellanic Cloud, both of which orbit our own Milky Way Galaxy. But as they go around the Milky Way, they are also orbiting each other. Each one tugs at the other, and one of them has pulled out a huge cloud of gas from its companion.
A new app developed by NASA JPL called Spacecraft AR uses the latest augmented reality technology to put virtual 3-D models of NASA's robotic space explorers into any environment with a flat surface.
Radioisotope power systems provide the efficient, long-lasting power sources vital to the success of numerous NASA space missions. NASA SMD is sponsoring technology development efforts to improve Radioisotope Thermoelectric Generator (RTG) performance, both in terms of the thermal-to-electric conversion efficiency (~ 6.3% at beginning of life - BOL) and the degradation rate during the 17-year design life.
On the evening of March 18, step outside for a view of the crescent Moon, Venus, and Mercury together above the twilight horizon.
NASA has powered on its latest space payload to continue long-term measurements of the Sun's incoming energy. Total and Spectral solar Irradiance Sensor (TSIS-1), installed on the International Space Station, became fully operational with all instruments collecting science data as of this March.
