To the casual onlooker, the space between the stars is benign and inactive. However, this space, also called the interstellar medium, is very active and contains the raw materials for future solar systems.
On February 21, 2016, the Colorado High-resolution Echelle Stellar Spectrograph (CHESS) will fly on a NASA suborbital sounding rocket on its second flight in two years to study the atoms and molecules in the interstellar medium.
Watching the sun is dangerous work for a telescope. Solar instruments in space naturally degrade over time, bombarded by a constant stream of solar particles that can cause a film of material to adhere to the optics. Decades of research and engineering skill have improved protecting such optics, but one crucial solution is to regularly recalibrate the instruments to accommodate such changes.
In mid-May, the seventh calibration mission for an instrument on NASA’s Solar Dynamics Observatory, or SDO, will launch into space onboard a sounding rocket for a 15-minute flight. The instrument to be calibrated is called EVE, short for the EUV Variability Experiment, where EUV stands for extreme ultraviolet. EVE’s job is to observe the total energy output of the sun in EUV light waves. The calibration mission is scheduled to launch on May 21, 2015, on a Terrier-Black Brant suborbital sounding rocket around 3 pm EDT from White Sands Missile Range, New Mexico.
