April 12 Membership Meeting

The April 12, 2021 membership meeting of the Cuyahoga Astronomical Association (CAA) will take place via the Zoom online service beginning at 7:30 p.m.

The evening’s speaker will be Joe Kolecki, retired NASA Scientist, speaking on “Physics and Experience, it’s all relative!” Kokecki said, “I am mostly going to focus on observable effects. The merging of physics and geometry will be approached from the perspective that scientific facts arise from measurement (metros, Gk.) and that time and space measurements are interconnected in relativity through the speed of light. Thus united, time and space can be dealt with as geometry.” An aerospace engineer, he retired from NASA in 2006. His work included developing orbital flight systems for generating and processing electrical power in space. Kokecki has worked in the United States and abroad on flight systems for Earth orbit and for interplanetary exploration. He also identified and developed mitigation strategies for electrostatic charging of vehicles and astronauts moving about and working of the surface of Mars. His interest in relativity came about early in life when he discovered an article on Einstein and set out to see what his work was all about. Relativity became a life-long passion and he has written books on the mathematics involved with the theory.

Attendees may join the Zoom meeting beginning at 7:20 p.m. the nights of CAA scheduled meetings and meetings begin at 7:30.

The evening will begin with introductions and the featured speaker followed by the monthly membership business meeting, typically concluding at about 9 p.m.. Guest attendees are welcome.

NASA HQ named for Mary W. Jackson, of “Hidden Figures” fame

NASA Administrator Jim Bridenstine announced Wednesday the agency’s headquarters building in Washington, D.C., will be named after Mary W. Jackson, the first African American female engineer at NASA.

Jackson started her NASA career in the segregated West Area Computing Unit of the agency’s Langley Research Center in Hampton, Virginia. Jackson, a mathematician and aerospace engineer, went on to lead programs influencing the hiring and promotion of women in NASA’s science, technology, engineering, and mathematics careers. In 2019, she was posthumously awarded the Congressional Gold Medal.

“Mary W. Jackson was part of a group of very important women who helped NASA succeed in getting American astronauts into space. Mary never accepted the status quo, she helped break barriers and open opportunities for African Americans and women in the field of engineering and technology,” said Bridenstine. “Today, we proudly announce the Mary W. Jackson NASA Headquarters building. It appropriately sits on ‘Hidden Figures Way,’ a reminder that Mary is one of many incredible and talented professionals in NASA’s history who contributed to this agency’s success. Hidden no more, we will continue to recognize the contributions of women, African Americans, and people of all backgrounds who have made NASA’s successful history of exploration possible.”

The work of the West Area Computing Unit caught widespread national attention in the 2016 Margot Lee Shetterly book “Hidden Figures: The American Dream and the Untold Story of the Black Women Mathematicians Who Helped Win the Space Race.” The book was made into a popular movie that same year and Jackson’s character was played by award-winning actress Janelle Monáe.

“We are honored that NASA continues to celebrate the legacy of our mother and grandmother Mary W. Jackson,” said, Carolyn Lewis, Mary’s daughter. “She was a scientist, humanitarian, wife, mother, and trailblazer who paved the way for thousands of others to succeed, not only at NASA, but throughout this nation.”

Ride the rover to the surface of Mars

February 22, 2021 — New video from NASA’s Mars 2020 Perseverance rover chronicles major milestones during the final minutes of its entry, descent, and landing (EDL) on the Red Planet on Feb. 18 as the spacecraft plummeted, parachuted, and rocketed toward the surface of Mars. A microphone on the rover also has provided the first audio recording of sounds from Mars.

From the moment of parachute inflation, the camera system covers the entirety of the descent process, showing some of the rover’s intense ride to Mars’ Jezero Crater. The footage from high-definition cameras aboard the spacecraft starts 7 miles (11 kilometers) above the surface, showing the supersonic deployment of the most massive parachute ever sent to another world, and ends with the rover’s touchdown in the crater.

Perseverance lowered safely to Martian surface

This high-resolution still image is part of a video taken by several cameras as NASA’s Perseverance rover touched down on Mars on Feb. 18, 2021. A camera aboard the descent stage captured this shot. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust). Subsequent NASA missions, in cooperation with ESA (the European Space Agency), would send spacecraft to Mars to collect these cached samples from the surface and return them to Earth for in-depth analysis. The Mars 2020 mission is part of a larger program that includes missions to the Moon as a way to prepare for human exploration of the Red Planet. JPL, which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance and Curiosity rovers.
