NASA Missions Explore a ‘TIE Fighter’ Active Galaxy
Not so long ago, astronomers mapped a galaxy far, far away using radio waves and found it has a strikingly familiar shape. In the process, they discovered the object, called TXS 0128+554, experienced two powerful bouts of activity in the last century. NASA’s Fermi Gamma-ray Space Telescope reported that TXS 0128+554 is a faint source of gamma rays, the highest-energy form of light. Scientists have since taken a closer look using the Very Long Baseline Array and NASA’s Chandra X-ray Observatory.

Rocket Science in 60 Seconds: What Are the SLS Boosters?
NASA’s powerful Space Launch System rocket will launch NASA’s Artemis missions to the Moon. Its two, five-segment solid rocket boosters provide more than 75% of that thrust power during launch and flight. In this episode of Rocket Science in 60 Seconds, SLS booster subsystem manager Julia Khodabandeh explains how the boosters are designed, manufactured, and assembled to help power NASA’s next-generation Moon missions.

To the Moon and Beyond: SLS Flight Support Booster Test
To support future flights of NASA’s powerful Space Launch System rocket, the agency and Northrop Grumman, the SLS booster lead contractor, will conduct a full-scale Flight Support Booster test in Promontory, Utah, on Sept. 2. The Flight Support Booster test builds upon prior tests of the rocket’s solid rocket booster to evaluate improvements and new materials in the boosters for missions beyond Artemis III.

NASA’s Green Propellant Infusion Mission Nears Completion
NASA has validated a new type of propellant for spacecraft of all sizes. Instead of toxic hydrazine, space missions can use a less toxic, "green" propellant and the compatible technologies designed to go along with it. In a little over a year since launch, NASA's Green Propellant Infusion Mission successfully proved a never-before-used propellant and propulsion system work as intended, demonstrating both are practical options for future missions.

Mission Complete: NASA Announces Artemis Generation Winners of Human Exploration Rover Challenge
This year’s on-site competition activities for NASA’s Human Exploration Challenge at the U.S. Space & Rocket Center in Huntsville, Alabama, were canceled due to the COVID-19 pandemic. However, high school and college teams competed in multiple design, documentation, and presentation categories, and were recognized for their successful efforts.
