Perseverance Mission Highlights CRISM’s Continued Contributions to Martian Science By Michael Buckley
On ancient Mars, water carved channels and transported sediments to form fans and deltas within lake basins. Examination of spectral data acquired from orbit shows that some of these sediments have minerals that indicate chemical alteration by water. In the Jezero crater delta, above, sediments contain clays and carbonates. This image, which includes information from the APL-built Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), originally appeared in a paper by CRISM deputy principal investigator and Perseverance mission team member Bethany Ehlmann.

Purpose: The subcommittee will receive testimony from non-government witnesses who will, in their personal capacities, provide insight into the current innovation landscape and discuss opportunities for the Department of Defense to invest in, harness, and transition the innovation, science, and technology required to ensure the U.S. military’s future edge.
US Black Engineer
GM’s Gerald Johnson recognized as 2021’s Black Engineer of the Year Published February 14, 2021 By : Lango Deen
The 2021 Black Engineer of the Year Awards (BEYA), held Thursday, Feb. 11 through Saturday, Feb. 13, was an all-digital event. This year’s conference theme was “Stand Up. Step Up. Make a Change,” a call to social justice action. Participants in science, technology, engineering, and math (STEM) fields had access to 24 hours of events, award shows, and entertainment.
An iconic line up of stars, including jazz saxophonist Gerald Albright, singer Parris Lane, and Detroit’s DJ Smooth, headlined performances featuring music that celebrated 500 years of African American culture, the contributions of Historically Black Colleges and Universities (HBCUs), and Blacks in the U.S. military and federal service.
Applied Physics Lab researchers develop advanced soft robots
The team s flexible, snail-like robot is untethered from a power source and controlled remotely, opening new possibilities for the burgeoning technology By Amanda Zrebiec / Published Jan 22, 2021
The pink strip lies flat on a black-and-white checkerboard surface. It s rubbery gummy, almost and just thicker than an unrolled fruit leather snack. At a glance, the strip seems unremarkable.
Introduce heat, however, and the strip transforms. Arching and extending, it wriggles like an inchworm, contorting itself independently. Remove the thermal stimulus, and the strip returns to its original form.
It seems like magic, or at least a trick of the imagination, but it s really just chemistry. What looks like a rubber strip is a piece of phase-changing material made of liquid crystal elastomers, or LCEs. The material, which becomes an artificial muscle of sorts, is programmed to rep
