I recently was invited to teach a week
long RTEMS class to 14 people at Johnson Space Center (JSC) . Multiple projects are considering using RTEMS and two are
being the trailblazers which bring RTEMS to JSC. Before saying
anything else, I want to thank the folks who invited me and were such
good hosts. In addition to a self-guided tour of the Rocket Park, I
got a field trip where I got to see a few of the interesting things
at JSC.
A complete set of photos from my field
trips are in a Facebook album. My field trips included seeing the
Saturn V rocket, space suits that had been to the moon, Morpheus
lunar lander, and the infamous Building 9 where the ISS and space
shuttle training modules, CanadARM, and zero-gravity practice
facilities. It also includes a small area of cool projects that
didn't make the cut including Robonaut and the movie-scary
Spidernaut. Everything I saw was impressive but much of it leaves
you with an unsettling feeling of sadness when you realize it has
been almost forty years since man went to the moon and, with the end
of the shuttle program, we have no ability to put a person in orbit.
Big science is not cheap and takes years of effort, but without it,
we quit learning more about our universe, getting insight into basic
physics, and solving the hard problems.
The Morpheus lunar lander is
one of the two projects taking the leap and switching to RTEMS. It
has already had multiple successful test flights and at least one
“interesting” one (videos). Morpheus uses a PowerPC based
computer system and is built using the Core Flight Executive from
Goddard Space Center. CFE has long supported RTEMS and as more
applications are based upon it, I am sure we will see at least a few
of those applications use RTEMS.
DownMASS is a small automated
capsule that can be filled with contents that need to be shipped from
the International Space Station (ISS). It is being designed to hold
approximately 100 pounds (43.5 kg) of cargo. When filled and released
from the ISS< it will reenter the Earth's atmosphere and
eventually deploy its parachutes. The hardware configuration for
prototyping is using a ruggedized embedded PC-104 system.
I am thrilled to see more space
applications using RTEMS – especially since have applications at
Johnson opens a potential path to having man-rated applications using
RTEMS. Thanks to Morpheus and DownMASS for giving RTEMS a chance.
