Solar winds are not the main culprit in stripping the planet’s atmosphere, a new study suggests.
Mars’s aqueous past holds the answers to many questions about the Red Planet. A new study provides a tool for scouring planetary surfaces for ancient shorelines.
Sediments from the Curiosity rover and experiments using tanks of gas and laser beams helped reveal how water continued to flow on Mars after the planet lost its atmospheric carbon dioxide.
The radar aboard the Mars Express spacecraft can generate ion beams arcing through space above the planet, which could lead to a new way of studying the plasma surrounding it.
A scientist on the rover team offers a remembrance of two intrepid explorers.
Dried-up rivers on Mars suggest that the planet was wet in the not-too-distant past.
Thermal modeling suggests that active magmatism in the past few hundred thousand years could account for the presence of a large lake previously hypothesized beneath the Red Planet’s southern ice cap.
The rover explored Mars’s surface for nearly 15 years and discovered ample evidence of the planet’s wet history.
The rover will explore a once water rich region on Mars’s surface and search for evidence of current and past life.
Lab experiments constrain conditions necessary for a key mineral to have formed in ancient lagoons and a crater lake.
