'It's 99% certain there is life on Mars': Shock finding as scientists re-analyse soil samples from Seventies Viking lander
Soil samples from Viking 1 lander which visited Mars in 1976
Mathematical analysis shows strong sign of organics
Samples had been dismissed as contaminated
'99% probability of life' claims one scientist
In July 1976, the Viking 1 probe touched down on Mars and failed to find traces of life - but now, three decades later, scientists think the experiment was flawed.
VIking 1 did find evidence of extraterrestrial microbes in soil samples from the Red Planet.
Mathematical analysis of the samples concluded that salts in the soil on Mars 'threw off' initial estimates - and that the soil samples show strong evidence of microbial life.
The new analysis looked for 'complexity' in the samples - an indication of life. To the surprise of the scientists, they found it.
