The search for signs of ancient Martian life is getting an airborne assist
of Mars material. But the team was eager to get the rover to Jezero’s 3.5 billion-year-old delta, where dramatic, wind-sculpted sandstone outcrops erupt from the planet’s vermillion sands. The height and inclination of those layered rocks reveal that Jezero’s potentially habitable lake may have a more complex past than orbital data suggest: At least once in Jezero’s history, the crater lake was too shallow to spill into an eastern outflow channel., the mission’s project scientist.
“Every grain potentially tells us a different story. It came from a different place, with a different history, and because the river channel that fed lake Jezero is very long, the grains we’re looking at could have come from way upstream—places we could never take the rover,” Farley says. “I’m excited because from the standpoint of the potential for preserving biosignatures, this seems like one that would be particularly good amongst the ones that have already been collected so far,” Wadhwa says.
“That’s something that has to be discussed more broadly with the team and with the science community,” Wadhwa says. “We’ll be seeking input.”Still, intentionally bringing bits of Mars back to Earth is no trivial task.

The Tharsis Region of Mars is Peppered With These Strange Pit Craters. Now They've Been Found ElsewherePit craters are found on solid bodies throughout our Solar System, including Earth, Venus, the Moon, and Mars. These craters – which are not formed by impacts — can be indications of underground lava tubes, which are created when the top of a stream of molten rock solidifies and the lava inside drains away, leaving … Continue reading 'The Tharsis Region of Mars is Peppered With These Strange Pit Craters.
