Latest Viking program Stories
New images from NASA's Mars Reconnaissance Orbiter show three additional NASA spacecraft that have landed on Mars: the Spirit rover active on the surface since January 2004 and the two Viking landers that successfully reached the surface in 1976.
Electricity generated in dust storms on Mars may produce reactive chemicals that build up in the Martian soil, according to NASA-funded research.
Thirty years after the first successful landing on Mars by NASA's Viking spacecraft, the ambitious mission continues to evoke pride and enthusiasm for future space exploration.
To learn if Mars ever supported life, researchers should look underground, a scientist presenting results of the Mars Express mission said at a conference this week.
A year and a half after twin robot rovers thrilled space fans with their hijinks on Mars, NASA is heading there again. A fourth Mars orbiter is set to blast off Wednesday, carrying some of the most sophisticated science instruments ever sent into space. The Mars Reconnaissance Orbiter will scan the desolate surface in search of sites to land more robotic explorers in the next decade.
Chosen to fly in 2011 as part of the European Space Agency's ExoMars mission, an instrument designed at UC Berkeley will look for an indisputable signature of life: the tendency of life-based amino acids to be either left- or right-handed. The instrument, the Mars Organic Analyzer, passed a key test this month in the most lifeless region of our planet, Chile's Atacama Desert.
The National Research Council was tasked with evaluating the risks of landing humans safely to work on Mars. What challenges might arise beyond the logistics of getting to Mars? Weather and biology might face astronauts working within an extended stay mission.
The NASA History Office has compiled a definitive account of the early robotic exploration of the martian surface. In this multipart series on the twin Viking landers that pioneered surface imagery and exploration on Mars, the events leading to the first and tense rocket-powered landing of Viking I are described.
