from a nationwide contest won by Valerie Ambroise, 12, whose winning essay discussed the importance of Sojourner Truth, aka Isabella Van Wagener. The Sojourner rover namesake spent nearly four months — 12 times its design lifetime — working on Mars: nestling up to rocks, analyzing their chemistry and relaying its observations to Earth.
The results, broadcast in real-time on early Internet networks, showed a Red Planet potentially habitable to life:"Resulting scientific findings suggested that Mars was at one time in its past warm and wet, with water existing in its liquid state and a thicker atmosphere," NASA's Jet Propulsion Laboratory in California, which managed the rover,A comparison of three generations of Mars rovers developed at NASA's Jet Propulsion Laboratory.
Today Sojourner serves as an important solar-powered ancestor for today's much larger, nuclear-powered rovers by NASA: Curiosity and Perseverance These rovers form part of a generation-long network of landers, orbiters and other vehicles exploring the Red Planet to make sense of its complex history.
