Small Packages to Test Big Space Technology Advances

When a recent cargo resupply mission to the International Space Station lifted off from NASA Wallops Flight Facility in Virginia, it carried among its supplies and experiments three cereal box-sized satellites that will be used to test and demonstrate the next generation of Earth-observing technology.  NASA has been increasing its use of CubeSats to put new technologies in orbit where they can be tested in the harsh environment of space before being used as part of larger satellite missions or constellations of spacecraft.  The three CubeSat missions launched on Orbital ATK's ninth commercial resupply mission represent a broad range of cutting-edge technologies housed in very small packages.

Two NASA ELaNa CubeSat Projects Illustrate the Program's Function as an Educational Platform

Two educational CubeSat missions were selected through the CubeSat Launch Initiative as part of the 14th installment of NASA's Educational Launch of Nanosatellites (ELaNa) missions. The ELaNa XIV mission was an auxiliary payload on the Nov. 18, 2017, launch of the Joint Polar Satellite System-1 satellite (now NOAA-20), a collaborative effort between the National Oceanic and Atmospheric Administration (NOAA) and NASA.

IceCube's First Global Map of Ice Clouds

Looking at Earth from the International Space Station, astronauts see big, white clouds spreading across the planet. They cannot distinguish a gray rain cloud from a puffy white cloud. While satellites can see through many clouds and estimate the liquid precipitation they hold, they cannot see the smaller ice particles that create enormous rain clouds.

An experimental small satellite has filled this void and captured the first global picture of the small frozen particles inside clouds, normally called ice clouds.  Deployed from the space station in May 2017, IceCube is testing instruments for their ability to make space-based measurements of the small, frozen crystals that make up ice clouds.

Over the past year, engineers tested the satellite's limits while on orbit. They wanted to see if the instrument's batteries stored enough power to run 24 hours. IceCube charges its batteries when the Sun shines on its solar arrays. During the test, although safeguards prevented the satellite from losing all its power and ending the mission, the test was successful. The batteries operated the IceCube all night and recharged during the day. This change made the CubeSat more valuable for science data collection.

Small Payload Rideshare Symposium
NASA Ames Research Center, California US
June 12-14, 2018
Jointly sponsored by t he Small Payload Ride Share Association and NASA's Small Spacecraft Systems Virtual Institute, this symposium  focuses on concepts and technologies to enable the small payload community to meet future launch needs and test new capabilities in a cost-effective manner. The symposium has evolved into a forum where the launch services community interacts with the small spacecraft community in a focused, working environment to address the needs of the community for affordable small payload access to space and the impediments hampering its success.

This year's symposium will highlight rideshares for swarms and constellations, as well as rideshares for beyond low Earth orbit. Aerospace companies, agencies, and individuals are encouraged to attend to network and present their respective small payload-related ideas and opportunities.

The event is open to a limited number of US citizens and permanent residents on a first come first served basis. Attendees will need to show identification to gain access to the Center. Participation by non-US citizens may be arranged. 

Please visit the symposium website for more information and to register:
