Studying the Ignorosphere … “I was surprised how big the event was, visually,” lead author Robin Wing, a researcher at the Leibniz Institute of Atmospheric Physics, said via email. He said people across northern Europe captured images of the burning debris, which was concentrated enough to enable high-resolution observations and to use atmospheric models to trace the ..

The way this document is written suggests that when NASA scores bidders for the Mars Telecommunications Network, the addition of a camera or other scientific payloads won’t be a net positive. However, if they pose an overall risk to the mission, they would be a net negative. New award to Rocket Lab may complicate things ..
DALLAS—The Space Force officer tasked with overseeing more than $24 billion in research and development spending says the Pentagon is more interested in supporting startups building new space sensors and payloads than adding yet another rocket company to its portfolio. The statement, made at a space finance conference in Dallas last week, was one of ..
Atmospheric scientist Laura Revell, with the University of Canterbury in New Zealand, presented research showing that rocket exhaust in the atmosphere can erase some of the hard-won gains in mitigating ozone depletion. In a high-growth scenario for the space industry, there could be as many as 2,000 launches per year, which her modeling shows could ..
The helium system on the SLS upper stage—officially known as the Interim Cryogenic Propulsion Stage (ICPS)—performed well during both of the Artemis II countdown rehearsals. “Last evening, the team was unable to get helium flow through the vehicle. This occurred during a routine operation to repressurize the system,” Isaacman wrote. The Space Launch System rocket ..
A second fueling test on NASA’s Space Launch System rocket ended Thursday night, giving senior managers enough confidence to move forward with plans to launch four astronauts around the Moon as soon as March 6. Unlike the first attempt to load propellants into the SLS rocket on February 2, there were no major leaks during ..
Still, after astronauts Butch Wilmore and Suni Williams eventually docked at the station, Boeing officials declared success. “We accomplished a lot, and really more than expected,” said Mark Nappi, vice president and manager of Boeing’s Commercial Crew Program, during a post-docking news conference. “We just had an outstanding day.” Over the subsequent weeks of the ..
Many European nations have their own satellite projects. Historically, their preference for launching on European rockets has not been as strong as it is for pan-European programs managed by ESA and the EU. So it has never been unusual to see a British, German, Spanish, or Italian satellite launching on a foreign rocket. This posture ..
Running solo After these astronauts departed on January 15, just a single NASA astronaut, Chris Williams, remained in orbit. He had reached space on board a Russian Soyuz spacecraft in November, alongside two Russian cosmonauts, Sergey Kud-Sverchkov and Sergei Mikaev. The space station is a big place, and with much of the facility now more ..
John Honeycutt, chair of NASA’s Artemis II mission management team, said the decision to relax the safety limit between Artemis I and Artemis II was grounded in test data. “The SLS program, they came up with a test campaign that actually looked at that cavity, the characteristics of the cavity, the purge in the cavity ..
