NASA SELECTS TEAMS FOR SPACE WEATTHER MISSION AND STUDIES
Four university teams will share $100 million to provide experiments
and supporting hardware for a future NASA mission to study near-Earth
space radiation. This type of radiation is hazardous to astronauts,
orbiting satellites and aircraft flying high altitude polar routes.
The teams will initially use $4.2 million to perform a one-year cost,
management and technical study prior to assembling and testing their
scientific payload for the mission. The anticipated lifetime cost of
payload development is $96 million.
Called the Radiation Belt Storm Probes, the two-spacecraft mission is
scheduled for launch in 2012. The mission will study how
accumulations of space radiation form and change during space storms.
Space weather storms involve constantly changing magnetic and
electric fields and gusts of radiation particles that produce intense
energy. This energy can black out long-distance communications over
entire continents and disrupt the global navigational system.
"This research will provide information to aid those working in this
environment to respond proactively to space radiation events, rather
than reactively," said NASA's Heliophysics Division director Dick
Fisher.
NASA also has selected three teams to share approximately $2.3 million
to conduct studies for small missions that will augment the 2012
mission. NASA will review the studies and select one investigation
for continued development.
Proposals for the 2012 mission and studies were submitted to NASA in
response to an Announcement of Opportunity released in August 2005.
Selected teams and experiments for the 2012 mission:
- Boston Univ., Boston; directly measure the near-Earth space
radiation particles to determine the physical processes that produce
radiation enhancements and loss
- University of Iowa, Iowa City, Iowa; understand the origin of plasma
waves that energize space particles to radiation levels; measure the
distortions to Earth's magnetic field that control the structure of
the planet's radiation beltssupports the creation of radiation
populations
Selected teams for studies and areas of research to augment the 2012
mission:
- University of Colorado at Boulder, Colo.; a potential U.S.
contribution of scientific instrumentation for a Canadian scientific
satellite
- University of Central Florida, Orlando, Fla.; measure the response
of the Earth's thermosphere and ionosphere to space weather forces
- Dartmouth College, Hanover, N.H.; seek to discover the mechanisms
that cause the Earth's radiation belts to periodically drain away
into the planet's atmosphere
The National Reconnaissance Office, Chantilly, Va., plans to enhance
the mission's scientific goals by contributing an experiment to
gather additional data that will better characterize the radiation
environment in space. The experiment will extend the measurement
capabilities to a range beyond what was originally planned for the
mission.
These investigations and the Radiation Belt Storm Probe mission are
part of NASA's Living with a Star Program. The program is designed to
understand how and why the sun varies, how planetary systems respond
and the effect on human space and Earth activities.
The program is managed by NASA's Goddard Space Flight Center,
Greenbelt, Md., for the agency's Heliophysics Division of the Science
Mission Directorate.

- University of Minnesota, Minneapolis; study electric fields in space
that energize radiation particles and modify the structure of the
inner magnetosphere
- New Jersey Institute of Technology, Newark, N.J.; determine how
space weather creates what is called the "storm time ring current"
around Earth and determine how that ring current supplies and
