Microbial life might survive today underground, in caves or under ice sheets.
A planetary scientist walks through the sensors and systems that went into the recent detection of potential biosignatures.
Unique, spotted rocks in Mars’ Jezero Crater could indicate that the planet once hosted life.
The rock is peppered with spots that could have been formed by microbes four billion years ago.
NASA hasn’t landed humans on Mars yet. But thanks to robotic missions, scientists now know more about the planet’s surface than they did when the movie was released.
NASA’s Curiosity rover has spotted carbon-containing minerals that can tell scientists more about what ancient Mars’ atmosphere may have looked like.
Scientists will have to check whether the samples contain living microbes before they can be safely studied.
The discovery indicates water may have remained stable on Mars for much longer than scientists thought.
Three Conversation science editors look ahead to what to expect in 2025 on The Conversation Weekly podcast.
The find has excited scientists, but other explanations are possible.
New US legislation could force Nasa to include enhanced cybersecurity for all its spacecraft.
New ideas will be key to making the mission happen after a report criticised its timescale and cost.
It’s not easy to collect rocks on a budget when the rocks are 140 million miles away.
Determining whether or not life exists on another planet is an extraordinarily complicated – and expensive – scientific endeavor.
Among the missions being planned is a huge helicopter drone to explore Saturn’s moon Titan.
Sophisticated equipment on the Perseverance rover is helping answer some of the many questions researchers have about Mars’ geology over time.
Discarded pieces of landing gear, crashed spacecraft and wear and tear have produced a lot of debris that is now scattered around the Martian surface.
Mars is the fourth planet from the Sun and one of our closest neighbors in space. But it’s not a very welcoming place for an Earthling to visit.
Perseverance and its helicopter sidekick, Ingenuity, have been on Mars for nearly nine months. The duo have taken rock samples, performed first flights and taken images of the delta in Jezero Crater.
