This Hubble telescope picture of Mars was taken Sept. 12, 1997, one day after the arrival of the Mars Global Surveyor (MGS) spacecraft and only five hours before the beginning of autumn in the Martian Northern Hemisphere.
This Hubble picture was taken in support of the MGS mission. Hubble is monitoring Martian weather conditions, such as large dust storms, during the early phases of the spacecraft's aerobraking.
