Hey Below the Fold fam,

We’ve all probably heard about the mission to Mars, but we’ll be the first to admit we haven’t completely understood what’s going on. And while we do know it takes time for communications from Mars to reach Earth, we didn’t know that there was an actual schedule for data drops from NASA’s Jet Propulsion Lab to the research community. That explains why these Mars stories come out in such close batches. Here’s some of the latest and why it matters.
TODAY'S STORY
Nearly a year into the mission to Mars
Fri Oct 8

It’s been nine months since the latest NASA rover reached Mars — what’s it been up to?! As a refresher, the Perseverance rover is on a mission to discover signs of ancient life and collect rock/dirt samples for possible return to Earth. Using Perseverance’s on-board technology, the NASA team has already analyzed rocks on the crater floor, so far discovering igneous ones.

And that’s quite exciting for scientists. Igneous rocks form when molten rock cools and crystallizes, and are great for getting accurate age dates to build a time scale, telling scientists when the red planet was habitable. Observations also suggest the rocks have had long, sustained interactions with water.

Why do we care about water on Mars? Well, on Earth, anywhere there’s water, there’s life. And finding signs of life on Mars would mean that Mars was not only habitable, but was actually inhabited (even if by very simple lifeforms such as microbes). This would increase the potential for life elsewhere, meaning we’re not alone in the universe. Further, the rich geological record of Mars — kept intact thanks to minimal tectonic plate activity — might even be able to detail how life formed on the planet.

Of course, this and other scientific questions depend on whether the rock samples are successfully returned to Earth. Perseverance’s first attempt at drilling returned an empty sample tube, likely because the rock selected was too weak from prior interaction with water and fell apart. Scientists later targeted — and successfully collected — two samples from rock that was more resistant to weathering. The mission to get these samples to Earth? Mars Sample Return.
