Say Cheese on Mars: Perseverance's Selfie With Ingenuity – NASA's Mars Exploration Program

Perseverance's Selfie with Ingenuity: NASA’s Perseverance Mars rover took a selfie with the Ingenuity helicopter, seen here about 13 feet (3.9 meters) from the rover. This image was taken by the WASTON camera on the rover’s robotic arm on April 6, 2021, the 46th Martian day, or sol, of the mission. Credits: NASA/JPL-Caltech/MSSS. Full image and caption ›

NASA’s newest Mars rover used a camera on the end of its robotic arm to snap this shot of itself with the Ingenuity helicopter nearby.

Op-ed | Build a Robot Base on Mars - SpaceNews

T he triumphant landing of the Perseverance rover has inspired all Americans, and indeed much of the world. President Biden should follow it up by launching the program to send humans to Mars.

These are questions that thinking men and women have wondered about for thousands of years. They can only be resolved by sending humans to Mars.

Some say that sending humans to Mars is a task for the far future, far beyond our abilities. In fact, the means to do such a mission are close at hand.

NASA's Odyssey Orbiter Marks 20 Historic Years of Mapping Mars

NASA's 2001 Mars Odyssey spacecraft launched 20 years ago on April 7, making it the oldest spacecraft still working at the Red Planet. The orbiter, which takes its name from Arthur C. Clarke's classic sci-fi novel "2001: A Space Odyssey" (Clarke blessed its use before launch), was sent to map the composition of the Martian surface, providing a window to the past so scientists could piece together how the planet evolved.

Odyssey's two decades of data have been a boon for researchers working to determine where water ice is locked up on the planet. Understanding the water cycle on Mars – a planet that was once much wetter, like Earth – offers insights into the way it has changed over time: How does water move around the planet today? Does the tilt of the planet affect where ice is stable? Odyssey's discoveries have helped chip away at those questions.

New research shows that Mars did not dry up all at once | EurekAlert! Science News

LOS ALAMOS, N.M., April 8, 2021-While attention has been focused on the Perseverance rover that landed on Mars last month, its predecessor Curiosity continues to explore the base of Mount Sharp on the red planet and is still making discoveries. Research published today in the journal Geology shows that Mars had drier and wetter eras before drying up completely about 3 billion years ago.

Sols 3083-3084: 'Mont Mercou,' in the Rear View – NASA's Mars Exploration Program

Sol 3081 will be a busy one for Curiosity. The rover is still near the transition between the "Glasgow" member and the sulfate-bearing unit; as this is a major geologic transition, the science team is trying to get as much data as possible before moving away.

First up, the rover is planning to do a “touch-and-go,” performing contact and targeted remote science before driving away. First, Curiosity will get some arm exercise in, doing APXS and MALHI observations of “Puymangou,” a dark spot on a bedrock slab in front of the rover. Science will test if the color difference represents a difference in composition relative to the nearby bedrock.

This weekend, Shayna Hume will blast off on an adventurous journey: The avid space buff, a graduate student in the Ann and H.J. Smead Department of Aerospace Engineering Sciences at CU Boulder, is heading to Mars (or at least as close to Mars as you can get on Earth).

After the Dust Cleared: New Clue on Mars' Recurring Slope Lineae - Eos

Recurring slope lineae (RSL) are dark lines that appear on steep slopes, then lengthen, fade, and reappear, typically annually. Proposed explanations for their formation involve either the flow of liquid or dry sediment, with varying triggering mechanisms. McEwen et al. [2021] report a significant increase in the number of RSL detections following the planet-encircling dust storm on Mars in 2018, compared to previous years.

Fuad ’23 and Sloan ‘23.5: Opacity, delays and power imbalances thwart Brown's PPSD Fund Committee

An unexpected snowfall closed schools in Huntsville, Alabama on the afternoon of Feb. 18. Despite the cold, NASA scientist Caleb Fassett MS'05 PhD'08 was grateful to have his two first-grade daughters home to witness a key moment in space exploration. When he was a graduate student nearly two decades before, he had hardly dared to think this day would come.

Spooky 'spiders on Mars' finally explained after two decades | Space

Those patterns, visible in satellite images of the Red Planet's south pole, aren't real spiders, of course; but the branching, black shapes carved into the Martian surface look creepy enough that researchers dubbed them "araneiforms" (meaning "spider-like") after discovering the shapes more than two decades ago.

The Martian atmosphere contains more than 95% carbon dioxide (CO2), according to NASA , and so much of the ice and frost that forms around the planet's poles in winter is also made of CO2. In a 2003 study , researchers hypothesized that the spiders on Mars could form in spring, when sunlight penetrates the translucent layer of CO2 ice and heats the ground underneath. That heating causes the ice to sublimate from its base, building up pressure under the ice until it finally cracks.
