A NASA-funded CubeSat, built and operated at LASP, will study the inner radiation belt of Earth’s magnetosphere, providing new insight into the energetic particles that can disrupt satellites and threaten spacewalking astronauts.
The $4 million Cubesat: Inner Radiation Belt Experiment (CIRBE) mission, tentatively slated for a 2021 launch, will provide some of the first advanced resolution of one of Earth’s two Van Allen belts, a zone that traps energetic particles in the planet’s magnetic field. This powerful radiation, known to physicists since the late 1950s, poses a hazard to solar panels, electronic circuitry, and other hardware onboard spacecraft traveling at and beyond low-Earth orbit.
The bread loaf-sized Miniature X-Ray Solar Spectrometer (MinXSS) CubeSat will be deployed from an airlock on the International Space Station (ISS) at 4 a.m. MDT on Monday, May 16, beginning its journey into space where it will study emissions from the sun that can affect ground-based communications systems.
The NASA-funded MinXSS, designed, built, and operated by University of Colorado Boulder students and faculty at LASP and CU-Boulder’s Aerospace Engineering Sciences Department (AES), will operate in Earth’s orbit for up to 12 months. The CubeSat will be deployed from the ISS via a special deployer designed by NanoRacks, LLC.
The MinXSS will observe soft X-rays from the sun, which can disrupt Earth’s upper atmosphere and hamper radio and GPS signals traveling through the region. The intensity of the soft x-ray emissions emitted from the sun is continuously changing over a large range—with peak emission levels occurring during large eruptions on the sun called solar flares.
A NASA-funded miniature satellite built by LASP and University of Colorado Boulder students will launch at 5:55 p.m. EST on Thursday from Cape Canaveral, Florida, the start of a six-month-long mission to study solar flares and the powerful X-rays emitted by the sun.
The Miniature X-ray Solar Spectrometer (MinXSS) CubeSat, which was built by students in CU-Boulder’s Department of Aerospace Engineering (AES) in collaboration with LASP researchers, will help shed light on how powerful electromagnetic emissions from the sun impact the Earth’s atmosphere, an effect known as space weather.
