The University of Colorado announced today that it has awarded a five-year contract to SES Government Solutions (SES GS), of Reston, Va., to host a NASA-funded science instrument on board SES-14, a communications satellite to be stationed over the Americas.
The Global-Scale Observations of the Limb and Disk (GOLD) mission, a NASA Explorers mission led from the University of Central Florida and built and operated at the University of Colorado (CU-Boulder), will collaborate with SES GS to place a science instrument on a commercial satellite as a hosted payload. This is the first time a university and a commercial spacecraft operator have teamed to host a NASA science mission. At a cost of roughly 10% of a traditional science satellite, working with a communications satellite represents the most cost-effective way to reach geostationary orbit.
The MAVEN spacecraft and all of its science instruments have completed their initial checkout, and all of them are working as expected. This means that MAVEN is on track to carry out its full science mission as originally planned.
The mission is designed to explore Mars’ upper atmosphere. It will determine the role that escape of gas from the atmosphere to space has played in changing the climate throughout the planet’s history. MAVEN was launched on November 18, 2013, and will go into orbit around Mars on the evening of Sept. 21, 2014 (10 p.m. EDT).
After a 5-week commissioning phase in orbit, during which it will get into its science-mapping orbit, deploy its booms, and do a final checkout of the science instruments, it will carry out a one-Earth-year mission. It will observe the structure and composition of the upper atmosphere, determine the rate of escape of gas to space today and the processes controlling it, and make measurements that will allow it to determine the total amount of gas lost to space over time.
