NASA’s Perseverance Now Autonomously Pinpoints Its Location on Mars
NASA’s Perseverance Now Autonomously Pinpoints Its Location on Mars

There is no GPS at the Red Planet, but a new technology called Mars Global Localization lets Perseverance determine precisely where it is — without human help.  Imagine you’re all alone, driving along in a rocky, unforgiving desert with no roads, no map, no GPS, and no more than one phone call a day for someone to inform you exactly where you are. That’s what NASA’s Perseverance rover has been experiencing since landing on Mars five years ago. Though it carries time-tested tools for determining its general location, the rover has needed operators on Earth to tell it precisely where it is — until now.   A new […]

NASA Let AI Drive the Perseverance Rover
NASA Let AI Drive the Perseverance Rover

In December, NASA took another small, incremental step towards autonomous surface rovers. In a demonstration, the Perseverance team used AI to generate the rover’s waypoints. Perseverance used the AI waypoints on two separate days, traveling a total o…

Could a toxic chemical in Mars dirt help us build a Red Planet base?

Perchlorate, a toxic substance found in Mars dirt, could help the bacterium Sporosarcina pasteurii strengthen bonds between particles of regolith.

Bleached Martian rocks offer fresh evidence of a wetter and warmer Mars: ‘But where did they come from?

“You need so much water that we think these could be evidence of an ancient warmer and wetter climate where there was rain falling for millions of years.”

Mars has never looked so serene in this gorgeous image from a NASA rover

Nearly 14 years ago, NASA’s Curiosity rover landed on Mars for a mission to explore the red planet and discover if it had an environment capable of supporting microbial life. Over the years, the rover has also been beaming back striking images of its s…

Mars orbiter sees odd etchings in the sand | Space photo of the day for Jan. 20, 2025

Even though the Red Planet’s atmosphere is thin, wind is still one of Mars’ most relentless sculptors.

Was the Red Planet once blue? New evidence points to an ancient ocean on Mars

Ancient shoreline features hint that water on Mars once formed a vast ocean.

After a month of no answer, NASA will try hailing its silent MAVEN Mars orbiter today

MAVEN was built to last in orbit until 2030 — that’s not looking likely anymore.

How Mars ‘punches above its weight’ to influence Earth’s climate

“Without Mars, Earth’s orbit would be missing major climate cycles. What would humans and other animals even look like if Mars weren’t there?”

How Mars’ ancient lakes grew shields of ice to stay warm as the Red Planet froze

The findings potentially solve the paradox of how liquid water seems to have persisted on Mars even when the climate grew too cold.
