SDO/EVE 7th underflight calibration rocket (NASA 36.336)

Date: Tuesday, June 12, 2018
Time: TDB
Location: White Sands Missile Range (WSMR), NASA’s sounding rocket facility in New Mexico. The SDO/EVE underflight calibration program is supported through NASA’s Sounding Rocket Program at the Goddard Space Flight Center’s Wallops Flight Facility in Virginia. NASA’s Heliophysics Division manages the sounding rocket program.

SDO/EVE Rocket Launch Information:

The SDO/EVE rocket program at LASP receives support from the NASA Solar Dynamics Observatory (SDO) mission in order to calibrate the SDO EUV Variability Experiment (EVE). Built and controlled by LASP, the EVE instrument measures solar extreme ultraviolet (EUV) irradiance, or the energy from the Sun that heats most of Earth’s thermosphere. EUV data help scientists understand the Sun’s influence on Earth and near-Earth space environment.

Sounding rocket launches are planned annually throughout the SDO mission’s five-year duration to ensure the accuracy of EVE-collected data by measuring any instrument degradation between the different rocket flights.

CHESS Rocket Launch Information:

The CHESS rocket program at LASP is led by principal investigator, Kevin France, and is supported through NASA’s Sounding Rocket Program at Wallops. NASA’s Heliophysics Division manages the sounding rocket program.

The Colorado High-resolution Echelle Stellar Spectrograph, or CHESS, was successfully conducted on June 26, 2017, on a NASA suborbital sounding rocket on its third flight in three years to study the atoms and molecules in the interstellar medium. CHESS-3 built on the first two flights of CHESS in May 2014 and February 2016, respectively, and was the mission’s most detailed survey yet. The scientists have used each to trial and improve the technology; CHESS-3 featured an upgraded diffraction grating, which reflects light and separates it into its different wavelengths.

The CHESS spectrograph provides information on how much of any given wavelength of light is present. CHESS-3 trained its eye at Beta Scorpii—a hot, brightly shining star in the Scorpius constellation well-positioned for the instrument to probe the material between the star and our own solar system. As light from Beta Scorpii streams toward Earth, atoms and molecules—including carbon, oxygen and hydrogen—block the light to varying degrees along the way.

CHESS-3 measured the composition, motion and temperature of interstellar material in unprecedented detail. Studying the interstellar medium allows investigators to look at two things. The first is to study the distribution of the raw materials available—such as carbon, nitrogen, and oxygen—for future generations of stars and planets. The second is to better understand the chemical and temperature structure of the Milky Way galaxy by measuring the temperature, composition, and velocity fields of the solar neighborhood.

Using this information on the availability and behavior of materials in space will allow scientists to predict if planets will form with atmospheres dominated by water or carbon-monoxide, making the worlds more or less likely to be potentially habitable.
