Maintaining astronaut bone and muscle health in microgravity is an
ongoing concern for NASA, and now the agency is "forcing" the issue with
a new investigation.
On May 29, 2014, NASA will fly the ForceShoe, designed by XSENS, to the
International Space Station (ISS) and, although these shoes don't
measure the same force of Star Wars lore, they will help NASA collect
data for studying the loads, or force, placed on crew member bodies
during exercise on the space station's Advanced Resistive Exercise
Device (ARED).
To reduce the loss of bone and skeletal muscle strength experienced by
astronauts during long duration spaceflight, NASA developed the ARED.
The device provides crew members with the ability to perform
weight-bearing exercises in space by supplying resistance through the
power of vacuum cylinders.
"ARED is a sophisticated exercise device," said Andrea Hanson, Ph.D. and
ISS Exercise Hardware Specialist. "Although it has helped NASA provide
better health outcomes for crew members, there is still progress to be
made in understanding the effects of exercise on bone and muscle health, and the ForceShoe will help us do that."
A small asteroid slammed into the Martian surface sometime between March 27 and 28, 2012, creating a crater swarm in the ground. The largest pit is 159 feet across.
Mars is turning out to be a useful laboratory for impact specialists. Aside from the occasional
meteorite spotted by NASA's rovers, cameras on orbiting spacecraft can readily spot new craters in the Martian surface. Sometimes they're seen as
splashes of bright, fresh ice against an otherwise drab landscape, and sometimes they create
dramatic ray patterns.

These
aren't the sorts of serendipitous discoveries that result from some
automated image-comparing algorithm. Instead, finding fresh craters
still relies on sets of human eyeballs scanning the wealth of spacecraft
imagery coming back from the Red Planet.
Such was the case with a
fresh impact spotted about two months ago. The telltale evidence wasn't
found in the super-high-resolution snapshots of the
HiRISE camera on NASA's Mars Reconnaissance Orbiter. Instead, it showed up in the daily "global weather" views returned by MRO's wide-angle
Mars Color Imager (MARCI).
