Visible matter in the form of stars and planets adds up to about five percent of the total known mass of the Universe. The rest is either dark matter, antimatter, or dark energy. The exact nature of these substances is unknown, but the International Space Station’s Alpha-Magnetic Spectrometer or AMS-02 is helping to solve the mystery. AMS-02 collects data on charged...
In June 2024, a new tail number swept the sky above NASA’s Armstrong Flight Research Center in Edwards, California. Pilots conducted flights of a Gulfstream IV (G-IV) to evaluate its handling characteristics and to familiarize pilots with it before it begins structural modifications. The research plane is joining the center’s fleet serving NASA’s Airborne Science...
Using cameras designed for navigation, scientists count ‘fireflies’ to determine the amount of radiation the spacecraft receives during each orbit of Jupiter. Scientists with NASA’s Juno mission have developed the first complete 3D radiation map of the Jupiter system. Along with characterizing the intensity of the high-energy particles near the orbit of the icy moon...
Developed by the agency’s Jet Propulsion Laboratory, the imaging spectrometer will provide actionable data to help reduce emissions that contribute to global warming. Tanager-1, the Carbon Mapper Coalition’s first satellite, which carries a state-of-the-art, NASA-designed greenhouse-gas-tracking instrument, is in Earth orbit after lifting off aboard a SpaceX Falcon 9...
The primary instrument for NASA’s Nancy Grace Roman Space Telescope is a sophisticated camera that will survey the cosmos from the outskirts of our solar system all the way out to the edge of the observable universe. Called the Wide Field Instrument, it was recently delivered to the agency’s Goddard Space Flight Center in Greenbelt, Maryland. The camera’s large field...
After six months of effort, an instrument that helps the Mars rover look for potential signs of ancient microbial life has come back online. The SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals) instrument aboard NASA’s Perseverance Mars rover has analyzed a rock target with its spectrometer and camera for the first...
NASA, on behalf of the National Oceanic and Atmospheric Administration (NOAA), has selected BAE Systems (formerly known as Ball Aerospace & Technologies Corporation) of Boulder, Colorado, to develop an instrument to analyze ocean data as part of NOAA’s Geostationary Extended Observations (GeoXO) satellite program. This cost-plus-award-fee contract is valued at...
NASA, on behalf of the National Oceanic and Atmospheric Administration (NOAA), has selected BAE Systems (formerly known as Ball Aerospace & Technologies Corporation) of Boulder, Colorado, to develop an instrument to monitor air quality and provide information about the impact of air pollutants on Earth for NOAA’s Geostationary Extended Observations (GeoXO)...
