With the recent discovery of the NASA Curiosity Rover that there is no methane gas on Mars' surface, can this lead to the end of the all-time hit discussion that there is extraterrestrial life in the planet?

According to CNET's report though, Robert Zubrin, the Mars Society president said that life may still exist in Mars since NASA's rover was only able to analyse a small part of it yet. It was just last week when the U.S. space agency said that the microbes living underneath its surface are unlikely to be discovered since they failed to find the methane gas produced by living organisms.

Mr Zubrin added that if there is a flaw with the NASA journey to the red planet is that the agency "doesn't have a goal," Daily Mail UK reports. It was followed with the findings of the NASA Curiosity Rover that were presented during the European Planetary Science during the earlier parts of September. It gave emphasis to one of the greatest finds of the Curiosity that the atmosphere in Mars had more oxygen than that of Earth's, leading to serious proof that there could possibly be aliens living in it.

Jim Green, the planetary sciences division director at NASA mentioned that the Curiosity Rover's goal is to fully understand Mars' history and not just take glimpses of it up there in space, The Sydney Morning Herald stated. Another lead scientist for the Mars Exploration Program of NASA added a supportive note to the matter at hand. "It's possible that we don't understand something that's going on in the Martian atmosphere," he said.

Mroeover, Mr Zubrin being the head of the Mars Society, mentioned that life in Mars is something that is still a mystery worth digging deeper into.

In the meantime, NASA's Curiosity Rover is keeping an eye on two possible comets that might pass through Mars which is causing high concern whether some of its particles might hit the spacecraft, NBC News stated.
