Oops? Life on Mars may have been found — before it was accidentally destroyed during a NASA mission nearly 50 years ago, one scientist has suggested. In 1975, just six years after Apollo 11 touched down on the moon,

In all our explorations of Mars to date, no evidence has been found that meets the rigorous standards to claim that we have conclusively found life. But, decades ago in the 1970s, when the Viking landers became the first US mission to safely land on and ...

Astrobiologist Dirk Schulze-Makuch believes Nasa's Viking missions have inadvertently 'eliminated' Martian life. He also mentioned that Martian life may have adapted to the planet's dry environment

Dirk Schulze-Makuch is a scientist who thinks NASA's Viking landers could have inadvertently destroyed the life they were searching for. In this Q&A, we ask why.

The 1976 Viking landers were the first U.S. missions to land on Mars, conducting the only experiments dedicated to detecting biosignatures in Martian soil.

Astrobiologist Dirk Schulze-Makuch from the Technische Universität Berlin in Germany believes that humans may have unintentionally killed all life on Mars in the 1970s. NASA's Viking 1 mission in 1975 saw two spacecraft land on the Red Planet's surface and conduct an experiment involving mixing water and nutrients with collected soil samples.

A scientist has said NASA may have accidentally killed life on Mars during a research mission to find it. For decades, scientists have been trying to find any signs of life on the Red Planet with no conclusive evidence as of yet.

For decades, scientists have posited that to find life on Mars they first need to find water. And in the absence of water, they have tried to see what happens when they introduce it onto the planet.

NASAs Viking missions sought life on Mars in the 1970s, but new insights suggest their methods might have unintentionally destroyed potential Martian microbes.
