We can close ourselves in the discovery of alien life. Are we ready?



In the next decade, it is possible that you will see a headline reporting that NASA has found evidence of life in space.

Will this news cause you running screaming outside? A recent article in the Sunday Sunday Telegraph hints that NASA's Jim Greene, director of Planetary Sciences, believes the public may be disrupted by the discovery of biology outside our planet. But Green doesn't really believe that. He is concerned that we have not thought too much about the next steps of scientists, whether we should suddenly face the reality of Martian life.

Here is the backstory: In 2020, Mars and Earth will again be relatively close to each other in their neighboring orbits around the sun. To take advantage of this random orbit, space agencies will lobby a small crew of spaceships to the Red Planet. Unlike the employers now occupied by the dusty landscapes of Mars, this new ship, launched by NASA and European-Russian cooperation, will be engaged in a type of exploration that has not been attempted since the NASA Vikings landed there in the mid-1

970s. The new craft goes beyond simply exploring places that were once livable. They will seek life. Dead or alive.

Soon, the departure of these new robotics researchers prompted Green to say that we can learn about life on Mars in a few years. They could dig up convincing evidence of biology. But he also said that the next steps are murky. Now he did not say that news of extraterrestrial life inevitably disturbs the public. We know it won't, because, after all, we conducted this experiment more than two decades ago.

In 1996, the blockbuster news story was a statement that fossil microbes were found in a meteorite known as the onion of ancient Martian regolith, or soil. The meteorite – known as ALH 84001 – was a small sample of Mars that apparently contained shady corpses of ancient germs.

It was a huge story, but the public reaction was as calm as dawn. People just wanted to know more. Unfortunately, the story of the Martian meteorite has changed as evidence has been explored by other researchers. The argument for the ancient germs on the Red Planet was weak.

The fact is that the public found the story intriguing but not disturbing. It was about life on Mars, but about life like bacteria – and long dead.
