Radiation's effects on electronics in space

This is what has prompted my research....   If you read the Spudnick
articles at the NY Times you will see that this is the group that handles
our classified satellites.


On one of the space missions the astronaut was hit space dust and was
hysterical about it.  We never heard about it again. This kind of high speed
pelting can wipe out electronics and most definitely software. Anyone know
what mission this was?  I would love to have a sound byte to put on my web.
I noticed that NASA is pulling pages off their web about Satellites....  Go
figure. :-)


BAA 642

The effect of radiation from natural and artificial sources on military
systems, notably satellites, must be determined and prevented. The sources
include radiation belts and cosmic rays in space and nuclear radiation
environments. The military systems of interest range from space systems to
systems employed in the atmosphere. The effects of interest range from low
level single event upsets to high level total dose effects, regardless of
dose rates.

The Naval research Laboratory is interested in receiving proposals which
address the effects, susceptibility and hardening of military systems to
particulate radiations regardless of source. Semiconductor and
superconductor devices, solar cells, and materials are of interest. Space
experiments, photonics, and particle and radiation detectors are also of
interest. Devices and subsystems which are important to future space
systems, but which have questions about survivability in the earth's
radiation belts, are of particular interest. The proposals may deal
exclusively with, or involve a combination of theoretical and computational
work, and laboratory or field testing. An additional area of interest is in
Arctic pollution. Awards under this BAA will not be made to harden existing
devices except to the extent that such a "hardening" demonstrates how the
proposed research will advance the state-of-the-art.
The foregoing description should be interpreted within the following
guidelines which apply to all BAA topics but are stated here for emphasis:
(1) NRL is not interested in concepts that already have been developed or
proven (even if they never have been sold before); (2) NRL seeks proposals
for scientific study and experimentation directed toward advancing the
state-of-the-art or increasing knowledge or understanding; and (3)
deliverables should demonstrate the results of scientific study and
experimentation rather than focus on a specific system or hardware solution.

Work to be accomplished under any resultant contract may be classified to
the level of Secret and may require access to and storage of classified
It is anticipated that projects may span two years. Proposals for lesser
periods and/or stand-alone subsets of the effort, each individually priced,
are encouraged.
Address Initial Proposals to James C. Ritter, Code 6610, (202) 767-2124.
Allow one month before requesting confirmation of receipt of Initial
Proposal, if confirmation is desired. Substantive contact should not take
place prior to evaluation of an Initial Proposal by NRL. If necessary, NRL
will initiate substantive contact.
