NASA's Perseverance rover has kicked off its highly anticipated science campaign with a Red Planet road trip.
The car-sized Perseverance landed inside Mars' 28-mile-wide (45 kilometers) Jezero Crater on Feb. 18. The six-wheeled robot's first few months on the Red Planet were devoted primarily to performing health and instrument checkouts and documenting the pioneering flights of NASA's Ingenuity helicopter , which traveled to Mars on Perseverance's belly.
How Do You Make a Robot Walk on Mars? It's a Steep Challenge | WIRED
In these new experiments, the team programmed SpaceBok with more traditional, less springy gaits. Specifically, the researchers wanted to compare two kinds: a "static" gait, in which at least three limbs are making contact with the ground at any given time, and a "dynamic" one, in which more than one limb can leave the ground at once. The former is more methodical, but the latter is more efficient because it allows the robot to move faster.
The researchers also outfitted versions of SpaceBok with two kinds of feet: point and planar. The point feet have a small surface area, kind of like the hoof of an actual springbok. The planar feet, by contrast, are actually flat swiveling circles, which bend at an angle when the foot makes contact with the ground. Think of these more like snowshoes than hooves. Or really, they're like snowshoes with cleats, since they're studded with projections that help the foot grip the ground.
Why audio is the next frontier in Mars exploration | Digital Trends
You’ve seen the photos of Mars from the surface: The red-tinted dust, the sharp mountains, the desolate rock formations. For as long as we’ve had rovers on the red planet, since Viking 1 rolled onto martian soil in the 1970s, we’ve been fascinated by imagery of this alien world.
But now there’s a new way for us to experience Mars from here on Earth, and that’s by listening to it. Since its arrival on Mars in February 2021, NASA’s Perseverance rover has recorded sounds of itself in action and, last month, it was able to record audio of the Ingenuity helicopter in flight for the first time.
AAK, Mars partner on program supporting women shea collectors | 2021-06-14 | Candy Industry
Running until 2030, the Women in Shea (WISH) initiative aims to reach 13,000 women shea collectors from more than 150 communities in northern Ghana.
Stakeholders in the WISH initiative aim to bring economic and social benefits to the women in the program and promote environmental improvements for the shea tree parklands while meeting the growing market demand for high-quality shea kernels.
Project goals will be achieved through expanding the women's access to savings and financial credits, improving natural resource management techniques, and reducing the time burden and labor intensity of the work associated with shea kernel collection and processing. Each of these areas will enable the women in impacted communities to gain more from the kernels they collect.
Humans could reproduce on Mars due to durability of sperm
Mars: Humans Able to Reproduce on Planet, Sperm Can Survive for 200 Years
The findings were part of a six-year experiment in which scientists kept mouse sperm on the International Space Station and exposed it to radiation.
But after six years, scientists found that the mouse sperm stored on the space station was still healthy.
One of the study's authors, Professor Sayaka Wakayama, of Japan's University of Yamanashi, told The Daily Mail: "Many genetically normal offspring were obtained. These discoveries are essential for mankind to progress into the space age."
