The Curiosity expedition had revealed that Mars has carbon-based molecules that are the basis for life. However, what we didn’t know is that this discovery was initially made in the 1970s, with the Viking mission. Curiosity had made it to Mars in 2013, butit wasn’t the first to discover life in its basic form.
The 1970 Viking unit that had landed on Mars had found organic material. However, the unit made a mistake: it destroyed the finding while analysing the data.
Conspiracy theorists now claim that it could be intentional, although there is no apparent cause for such a move from NASA. The data was lost, according to NASA , as a result of the machine’s fault. The destruction of the material was caused as a result of the Viking unit’s heating each sample up to 500 degrees, which could have destroyed the organic material.
