Welcome to the American Geophysical Union fall meeting
edition of this week's International Space Updates.
The NASA Time History of Events and Macroscale Interactions during
Substorms
(THEMIS) mission, currently operated by the University of California,
Berkeley,
is ready to move
its five satellites into "prime observing position" next
January. NASA launched THEMIS to help study what and why auroras
occurring
in Earth's atmosphere have the ability to change from a small wave of
light to
a spectacular and beautiful streak of color. It will hopefully be
possible to learn more about the connection between the Sun and Earth,
and how
Earth's magnetosphere works.
So far, researchers have observed "the dynamics of a rapidly developing
substorm, confirm the existence of giant magnetic ropes and witness
small
explosions in the outskirts of Earth's magnetic field."
Researchers still evaluate scientific data in an attempt to locate
liquid water
or water vapor on other planets. According to NASA scientists
evaluating
data gathered by the Cassini spacecraft, it is possible the Saturn moon
Enceladus
still has water - and may even have life. The images taken by
Cassini
revealed icy jets being shot out of a "near-surface pockets" of water
located on the surface of Enceladus - further flybys will need to occur
before
scientists are completely sure about the possibility of liquid water.
As the NASA Mars rovers must find safe locations to "hibernate"
during the harsh Martian winter, engineers are using new software
technology to
locate possible safe havens for the rovers. The rover Spirit
could use
the "Von Braun" section of Mars, but all paths to get to the Martian
mesa are all too dangerous to use with the rough weather quickly
approaching. According to software used
by Ohio State University researchers, if Spirit attempts to reach
Von Braun
but is unable to due to the difficult landscape, there aren't very many
ideal
locations for the rover to take temporary refuge before continuing its
trip.
The software can also help plan out future mission routes, assuming the
rovers
are still able to function normally after the winter ends.
