NASA Turns Off 2 Voyager Science Instruments to Extend Mission

The farthest-flung human-made objects will be able to take their science-gathering even farther, thanks to these energy-conserving measures. Mission engineers at NASA’s Jet Propulsion Laboratory in Southern California turned off the cosmic ray subsystem experiment aboard Voyager 1 on Feb. 25 and will shut off Voyager 2’s low-energy charged particle instrument on March 24. Three […]

Novel Recuperator Design for Cryogenic Fluid Management System

Cryocoolers are essential systems in many space exploration missions to maintain propellants at cryogenic temperatures. Cryogenic recuperators are a key component of these cryocoolers and dictate the performance of the system. NASA is seeking to reduce the cost and increase the performance of cryogenic recuperators (also called Heat Exchangers) by utilizing Additive Manufacturing (AM) technologies. […]

Hubble Captures New View of Colorful Veil

In this NASA/ESA Hubble Space Telescope image, Hubble once again lifts the veil on a famous — and frequently photographed — supernova remnant: the Veil Nebula. The remnant of a star roughly 20 times as massive as the Sun that exploded about 10,000 years ago, the Veil Nebula is situated about 2,400 light-years away in the constellation […]
