What did Viking 2 find on Mars?

Search for life In addition, independent of the biology experiments, Viking 2 carried a Gas Chromatograph/Mass Spectrometer (GCMS) that could measure the composition and abundance of organic compounds in the Martian soil.

Is curiosity still working on Mars?

Curiosity is a car-sized Mars rover designed to explore the Gale crater on Mars as part of NASA’s Mars Science Laboratory (MSL) mission. The rover is still operational, and as of August 31, 2021, Curiosity has been active on Mars for 3224 sols (3312 total days; 9 years, 25 days) since its landing (see current status).

Is Viking 2 still working?

Viking Orbiter 1 continued for four years and 1,489 orbits of Mars, concluding its mission August 7, 1980, while Viking Orbiter 2 functioned until July 25, 1978.

What were the Viking 1 and 2 probes looking for on Mars?

About the mission The first spacecraft to successfully land on Mars, Viking 1 was part of a two-part mission to investigate the Red Planet and search for signs of life. Viking 1 consisted of both an orbiter and a lander designed to take high-resolution images, and study the Martian surface and atmosphere.

What did Viking 2 do on the surface of Mars?

Viking 2’s lander touched the Red Planet just weeks after its sibling, Viking 1. The lander spent more than three Earth years on the surface taking pictures of the surrounding area, analyzing the regolith in front of it, and even conducting life experiments.

What kind of power does the Mars rover Curiosity use?

Power source: Curiosity is powered by a radioisotope thermoelectric generator (RTG), like the successful Viking 1 and Viking 2 Mars landers in 1976. Radioisotope power systems (RPSs) are generators that produce electricity from the decay of radioactive isotopes, such as plutonium-238, which is a non- fissile isotope of plutonium.

What did NASA do with the Viking lander?

The seismometer on the lander was, however, inoperable. On July 28, 1976, the lander’s robot arm scooped up the first soil samples and deposited them into a special biological laboratory that included a gas chromatograph mass spectrometer.

When was the Viking 2 lander turned off?

The Viking 2 mission was part of the American Viking program to Mars, and consisted of an orbiter and a lander essentially identical to that of the Viking 1 mission. The Viking 2 lander operated on the surface for 1316 days, or 1281 sols, and was turned off on April 12, 1980 when its batteries failed.
