The solid-state data recorder.
N
ASA's Jet Propulsion Laboratory (JPL) selected solidstate
data recorders (SSDRs) from Mercury Systems for
NASA's Earth Surface Mineral Dust Source Investigation
(EMIT) science mission. The Earth Imaging Spectrometer
instrument containing the SSDRs is scheduled for launch to
the International Space Station (ISS) in 2022.
When strong winds on one continent stir up mineral rock
dust (such as calcite or chlorite), the airborne particles can
travel thousands of miles to affect entirely different continents.
Dust suspended in the air can heat or cool the atmosphere
and Earth's surface. This heating or cooling effect is
the focus of the EMIT mission.
Scientists know that most of the mineral dust transported
in Earth's atmosphere comes from arid regions around the
globe. But they aren't certain what types of minerals the
wind carries from those regions. Different minerals affect
the environment in different ways, so scientists need to know
what minerals are in dust source regions if they're going to
better understand how the dust is affecting the Earth. EMIT
will provide this missing dust source information.
The data will allow scientists to create a new mineral map
of Earth's dust-producing regions. The map will improve
computer models that scientists will use to assess the regional
and global heating and cooling effects of mineral dust
today and in the future.
The SSDRs are purpose-built to support the need for
ultra-reliable and agile radiation-tolerant storage devices.
