Scientists Track "Perfect Storm" on Mars A pair of eagle-eyed NASA spacecraft -- the Mars Global Surveyor (MGS) and Hubble Space Telescope -- are giving amazed scientists a ringside seat to the biggest global dust storm seen on Mars in several decades. The
Martian dust storm, larger by far than any seen on Earth, has raised
a cloud of dust that has engulfed the entire planet for the past
three months. As the Sun warms the airborne dust the upper atmospheric
temperature has been raised by about 80 degrees Fahrenheit. This
abrupt onset of global warming in Mars' thin atmosphere is happening
at the same time as the planet's surface has chilled precipitously
under the constant dust shroud.
