NASA’s Pandora Mission Begins Study of Exoplanets, Host Stars
Pandora, NASA’s newest exoplanet mission and the first satellite to launch through the agency’s Astrophysics Pioneers program, is now making unique observations of worlds beyond our solar system and the stars they orbit. The mission will determine the atmospheric make-up of at least 20 exoplanets, including the presence of hazes, clouds, and water. “Pandora’s data will help close a major…

Galactic Gems Glisten in New Gallery From NASA’s Chandra
Galaxies are like cosmic gems, each with characteristics including size and shape that make them distinct. A new gallery released today from NASA’s Chandra X-ray Observatory and other telescopes displays a collection of galactic images that showcase this variety. Astronomers put galaxies into three main categories: spirals like our own Milky Way with arms emanating from their cores, ellipticals that…

Integrating Model-Based Systems Engineering and Fault Management to Enable Autonomous Space Missions
Fully autonomous space mission operations require the ability to detect faults and compensate for them without human intervention. To address this challenge and provide model-based support for system design and operations, it is important to connect fault management (FM) and model-based systems engineering (MBSE). This approach was successfully demonstrated with the model-based generation of a failure modes and effects analysis…

Astronomy Picture of the Day
Comet 220P in Outburst Explanation: Comet 220P is unexpectedly bright. Normally, periodic Comet 220P/McNaught is so dim that to see it requires a telescope. Two surprising outbursts this year, however, have made it about 20,000 times brighter than usual, so that it is now visible with binoculars and long-duration camera exposures. As expected, Comet 220P continues to orbit the Sun between Mars and Jupiter with a period of over 5…

Starstruck: NASA Research Shows How Sun’s Ancient History Shaped Earth
At the center of our solar system, the Sun influences every planet that orbits it. In two recent NASA-funded studies, scientists uncovered how ancient events in the Sun’s history may have helped create Earth’s unique climate and driven previously unexplained climatic shifts. In new research, scientists at NASA’s SHIELD (Solar Wind with Hydrogen Ion charge Exchange and Large-Scale Dynamics) center — one of NASA’s DRIVE (Diversify, Realize, Integrate, Venture, Educate)…

MAIA Air Sensor at Work in Addis Ababa
Description This roof-mounted air sensor in Addis Ababa, the capital of Ethiopia, is one of 10 used by NASA’s Multi-Angle Imager for Aerosols (MAIA) to study the city’s air quality. MAIA’s air sensors provide a detailed look at particulate matter that is 2.5 micrometers or less in diameter, also known as PM2.5, one of the world’s deadliest forms of air pollution. Black carbon,…
