Mars looks dead, but don’t count it out just yet

Mars’ surface is a lifeless, unwelcoming desert. But beneath its red soil the planet still might be alive — geologically.

Big space news broke in 2018: Using a ground-penetrating radar aboard a Mars satellite, a group of scientists detected a thin 12-mile lake thousands of feet beneath the Martian south pole. Now, researchers have put forward a paper arguing that if there is indeed a sizable briny-lake underneath this ice cap, hot molten rock (magma) must have oozed up near the surface and melted the ice. 

Such underground volcanism would have happened in geologically recent time, perhaps a few hundred thousand years ago, or less.  Read more…

Opportunity Mars Rover goes to its last rest after extraordinary 14-year mission

Opportunity, one of two rovers sent to Mars in 2004, is officially offline for good, NASA and JPL officials announced today at a special press conference. “I declare the Opportunity mission as complete, and with it the Mars Exploration Rover mission as complete,” said NASA’s Thomas Zurbuchen.

The Opportunity rover is dead

The Opportunity rover is dead, at age 15. 

After spending over 5,000 Martian days rumbling through the inhospitable red desert planet, NASA acknowledged on Wednesday that its sun-powered exploration rover hasn’t responded to over 600 attempts at contact since June 2018, and is presumed dead. 

“I’m standing here with a sense of deep appreciation and gratitude to declare the Opportunity mission as complete,” Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate, said from NASA’s Jet Propulsion Laboratory in Southern California.

Deprived of sunlight by a dust storm the size of North America, Opportunity came to rest in a place known as “Perseverance Valley,” which sits on the edge of the 14-mile wide Endeavor crater. It is here that the 400-pound machine, built by NASA engineers in Southern California, will now spend millennia getting blanketed in red dust, for the Martian winds don’t ever stop blowing. Its batteries, completely bereft of power, will not turn on again. Read more…

NASA cubecraft WALL-E and EVE sign off after historic Mars flyby

A NASA mission that sent two tiny spacecraft farther out than any like them before appears to have come to an end: Cubesats MarCO-A and B (nicknamed WALL-E and EVE) are no longer communicating from their positions a million and two million miles from Earth respectively.
