A sharp-eyed satellite captured what may be some of the Artemis 1 moon mission's final moments on Earth.
Artemis 1 is scheduled to launch from NASA's Kennedy Space Center (KSC) on Wednesday (Nov. 16) during a two-hour window that opens at 1:04 a.m. EST (0604 GMT). You can watch the liftoff here at Space.com, courtesy of NASA.
Photographers have been assiduously chronicling the leadup to Artemis 1's highly anticipated launch, and we just got a nice and novel perspective on it thanks to Capella Space. One of the San Francisco-based company's satellites captured a high-resolution of the Artemis 1 stack — a Space Launch System (SLS) rocket topped by an Orion crew capsule — sitting on KSC's Pad 39B on Monday (Nov. 14).
The shot is black-and-white, for Capella Space specializes in synthetic aperture radar (SAR) rather than visible-light imaging. This strategy has some definite advantages.
"SAR sensors are self-illuminating and can penetrate clouds, fog, smog, darkness and smoke," Capella Space's website reads (opens in new tab). "Operated from low Earth orbit, Capella's SAR systems can reliably collect images in all weather conditions both night and day."
Capella Space sells the data collected by its satellites to a variety of customers, who use it for a wide range of purposes, from agricultural monitoring to the tracking of threats to national security. But the company also freely releases imagery of pressing importance, such as shots showing movements of Russian troops during the ongoing invasion of Ukraine.
Artemis 1 is the first mission for the SLS and for NASA's Artemis program, which aims to set up a crewed lunar base by the end of the 2020s.
If all goes according to plan, the SLS will launch Orion on an uncrewed mission to lunar orbit that will last about 26 days from liftoff to splashdown. Artemis 1 will be the second flight for Orion; a United Launch Alliance Delta IV Heavy rocket launched the capsule to Earth orbit on an uncrewed test flight in 2014.
