Radar imagery from a NASA Mars orbiter shows the Red Planet has been through cycles of climate change — and it’s currently thawing.
Mars is in the process of 370,000-year-old climate shift that, one day, will leave the Red Planet looking fairly pink, new research shows.
Evidence that Mars is emerging from an ice age comes from analysis of radar images showing dramatic variations within layers of ice inside the planet’s northern polar cap. As the planet warms, more ice collects on its polar regions, the reverse of long-duration climate shifts on Earth. The cycles are triggered by variations in the planets’ orbits around the sun and their axial tilts. Continue reading Mars Is Coming Out of an Ice Age
A specially-equipped 747 has detected atomic oxygen in Mars’ upper atmosphere, NASA reported, marking the first time that the space agency has made that observation in four decades. Continue reading Atomic Oxygen Detected on Mars
On Mars, formerly water-filled craters transformed to dry mile-high mounds with the help of wind, according to new research.
The results explain the geography of Gale Crater (the Curiosity rover’s landing site) as well as other high-topped places on the Red Planet, and confirm that wind is currently the dominant force in Mars’ geology. (Mars has no widespread plate tectonics or liquid water today). Continue reading Mysterious Mars Mounds Were Liquid-Filled Craters
NASA had hoped its next Mars probe would have launched by now. Instead, the agency is mulling whether to spend an extra $150 million to fix a problem with the spacecraft and re-target liftoff for May 2018, the next time Earth and Mars favorably align for flight. Continue reading Will NASA’s InSight Mars Mission Launch in 2018?
A volcano on Mars half the size of France spewed so much lava 3.5 billion years ago that the weight displaced the Red Planet’s outer layers, according to a study released Wednesday.
Mars’ original north and south poles, in other words, are no longer where they once were. Continue reading Monster Volcano Gave Mars Extreme Makeover
Sure, NASA’s Mars rover Curiosity has seen sand before, but this dune is by far the biggest and the six-wheeled rover is making the most of it.
Seen here on sol 1,228 (Jan. 19) of its mission, Curiosity another another picturesque selfie, using its robotic arm-mounted Mars Hand Lens Imager (MAHLI). MAHLI snapped 57 high-resolution Continue reading Sandbox Selfie! Curiosity Plays in Mars Sand Dune
