11 ore 14 min, 7 nov 1996 anni - Mars Global Surveyor
Highly successful orbiter (NASA)
Descrizione:
Mars Global Surveyor was the first completely successful Mars orbiter since Viking 1 shut down in 1980. The start of Mars Global Surveyor’s science mission was delayed due to a problem with one of its solar panels that caused its aerobraking period (which reduced its initial orbit from an ellipse to a low-altitude, near circular one) to last for a year and a half. Once science operations began in March 1999, Mars Global Surveyor provided scientists with a wealth of images and data, including the highest-resolution images yet achieved from orbit. Many of the Mars Observer instruments were re-flown on Mars Global Surveyor. Its mission was extended three times, making it the longest-lived spacecraft in Martian orbit at the time contact was lost on November 5, 2006.
