MinXSS data will also help us understand the physics behind solar flares. The soft X-rays carry information about the temperature, density and chemical composition of material in the sun's atmosphere, allowing scientists to trace how events like flares and other processes heat the surrounding material in the sun's atmosphere - which are still being debated among solar scientists.
On May 16, 2016, the NASA-funded MinXSS CubeSat deployed from an airlock of the International Space Station to enter an orbit around Earth. MinXSS observes soft X-rays from the sun -- such X-rays can disturb the ionosphere and thereby hamper radio and GPS signals. CREDIT Credits: ESA/NASA
CubeSats are a new, low-cost tool for space science missions. Instead of the traditional space science missions that carry a significant number of custom-built, state-of-the-art instruments, CubeSats are designed to take narrowly targeted scientific observations, with only a few instruments, often built from off-the-shelf components. For example, MinXSS uses a commercially purchased X-ray spectrometer for a detector and an extendable tape measure as a radio antenna. The MinXSS development program was funded by the NASA Science Mission Directorate CubeSat Initiative Program and implemented by the University of Colorado Boulder under the leadership of Principal Investigator Tom Woods.
MinXSS was launched via the NASA CubeSat Launch Initiative program on Dec. 6, 2015, aboard Orbital ATK's Cygnus spacecraft through NASA's Commercial Resupply Services contract. Since its inception in 2010, the CSLI has selected more than 120 CubeSats for launch and deployed 43 small satellites as part of the agency's Launch Services Program's Educational Launch of Nanosatellite Missions.
