PRESS RELEASE
Today the Sojourner rover will be powered on for the first time in over six months. It has been asleep, conserving its batteries, during the long cruise towards Mars.
During the past several months, the rover team has been operating a ground test vehicle identical in almost all respects to Sojourner. Through a series of "Operations Readiness Tests," or ORTs, the test vehicle has performed more than the equivalent of Sojourner's entire primary mission. Experience from these tests has lead to a small set of improvements in the rover's onboard software. These improvements, which have been fully validated during ORTs, will be sent to the Sojourner rover today in the form of a command sequence containing software "patches."
After the patches have been loaded onto the rover, it will then shut itself off. The rover will then be awakened again, activating the new software. Then a second command sequence will be sent to the rover, and it will perform a self-diagnostic status check, confirming the health of all onboard devices. The Alpha Proton X-ray Spectrometer (APXS) will also be activated to confirm that it is operating normally. Finally, the rover will shut itself down. The rover should next awaken on July 4, after Pathfinder lands on the surface of Mars.
