MinXSS-1 launched on ULA/Orbital-ATK OA-4 from Cape Canaveral on 2015 December 6 at 08:44:57.1 UTC.  The high resolution (4k) launch video is embedded below.

Deployment from the ISS was beautiful. It occurred on 2016 May 16 at 10:05:26 UTC. A high resolution (4k) video compilation of the photos taken of the deployment by astronauts on the ISS is embedded below.

Update 2016-06-13: We’re now done with commissioning and into normal science operations!

Update 2017-05-06: MinXSS-1 burned up in the atmosphere as planned! We were in normal science operations up until just 2 days before at least parts of it hit temperatures > 300 ºC and it burned up. MinXSS-2 is ready for delivery this year for a launch in late 2017, with a planned 5-year mission. The last received beacon was from a HAM operator in Australia at 2017-05-06 02:37:26 UTC.

MinXSS-1 was on orbit for 354 days, 16 hours, 32 minutes, and 0 seconds.

Making of MinXSS

The Miniature X-ray Solar Spectrometer (MinXSS) is a 4-year, ~$1 million project to design, build, integrate, test, and operate a 34cm x 10cm x 10cm satellite. Specifically, the intensity of the soft x-ray spectrum from 0.4 keV (30 Å) to 30 keV (0.4 Å) will be measured, with resolution of ~0.15 keV full-width half-max. This region is of particular interest for observations of solar flares and active regions. The MinXSS project heavily involves its graduate student team members with scientists and engineers at the University of Colorado, Boulder and the Laboratory for Atmospheric and Space Physics (LASP). Over 40 graduate students, 3 undergraduate students, and one high school student have worked on MinXSS.
