An image inside an oval, depicting two spacecraft, one a lander, and one a rover, on the surface of Mars. JPL” are written on the bottom. 280 million, including the launch vehicle and mission operations. Martian soil using three scientific instruments.

Mars meteorological station, collecting data about pressure, temperature, and winds. The rover also had two black-and-white cameras and a color one. Two black and white 0. It provided images of the APXS’s target area and the rover’s tracks on the ground. 6 cm details across a 0.

Scientists chose it because they found it to be a relatively safe surface to land on and one that contained a wide variety of rocks deposited during a catastrophic flood. Mars atmosphere in a retrograde direction from a hyperbolic trajectory at 6. The lander’s on-board computer used redundant on-board accelerometers to determine the timing of the parachute inflation. Twenty seconds later the heatshield was pyrotechnically released. When the lander reached 1.

6 km above the surface, a radar was used by the on-board computer to determine altitude and descent velocity. This information was used by the computer to determine the precise timing of the landing events that followed. Once the lander was 355 m above the ground, airbags were inflated in less than a second using three catalytically cooled solid rocket motors that served as gas generators. These were fired at 98 m above the ground. 15 and 25 m above the ground. 3 seconds, while the rockets were still firing, the lander cut the bridle loose about 21. 5 m above the ground and fell to the ground.

The first bounce was 15. Once the lander stopped rolling, the airbags deflated and retracted toward the lander using four winches mounted on the lander “petals”. Designed to right itself from any initial orientation, the lander happened to roll right side up onto its base petal. The lander had to wait until sunrise to send its first digital signals and images to Earth.
