Once upon a time on Mars



Three and a half billion years ago, waves and currents swept through the dusty area on Mars, now known as the Jezero Crater, on a nascent Earth. life

Astronomers, philosophers and science fiction writers have long wondered whether nature performed the same experiments on Earth. Is Mars the test tube for Darwinian evolution? You will no longer be laughed at from biology class for speculating on whether life evolved on Mars first and drifted to Earth with meteors or the two planets cultured by microbes or things. There is life from proto from somewhere far away.

So humans sent their offspring across 300 million miles of time and space in search of long-lost relatives, the ancient roots of a family tree that could be traced in the soil of the Red Planet.

The perseverance rover and its little sibling, the Ingenuity helicopter, landed in the clouds on February 18 with an antenna and a camera. The persistence will take on the next Mars year – the equivalent of Earth’s two years – prowl, poke, and collect rocks from Jezero Crater and the incoming delta. The rover will examine chemical and geological debris and take pictures so scientists on Earth can find traces of ancient fossils or other forms in which life could have formed.

Persistence and ingenuity work on a very long leash: 12 minutes of light travel time and an ether cross-signal delay from Pasadena, where builders and their bidders wait and see what they have accomplished. Like teenagers, where you open the door with your car keys, persistence and ingenuity is less intelligent and responsible than humans have trained them to be.

The rocks will be picked up and returned to Earth in a five-year series of maneuvers involving rockets, relays, rover and orbital displacement starting in 2026, which will make recalling the lunar rocks seem as easy. Sending holiday cookies to your relatives The rocks that return in 2031 will be examined for years, such as the Dead Sea Scrolls, for what they might say about the hidden history of our lost twins, and perhaps the earliest days of life in solar system

The generations after World War II performed the first large reconnaissance of the solar system. It may be the fate of this generation that will have to carry out the next big reconnaissance to find out if we have or ever had a neighbor on this planet.In the Jezero Crater, the dream remains. We may never have lived on Mars. But our machines have already made
