May 10 Membership Meeting to feature Sky & Telescope editor

Kelly Beatty

The May 10, 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 Kelly Beatty, Senior Editor of Sky & Telescope magazine, whose talk is entitled “Darkness in Distress”

Light pollution, simply put, is any unnecessary or excessive outdoor illumination. Sadly, it has become a pervasive and ugly consequence of modern 24/7 society. Light pollution robs us of the night sky’s beauty, negatively affects the ecosystem, and creates an in-your-face waste of energy. But a new mindset and new technology are poised to slow — and perhaps reverse — this bane of modern life. Learn how you can safely light up your home, business, and community without wasting energy, disturbing your neighbors, or creating an unhealthy environment for humans and wildlife.

Beatty has been explaining the science and wonder of astronomy to the public since 1974. An award-winning writer and communicator, he is a Senior Editor for Cambridge-based Sky & Telescope magazine. He enjoys sharing his passion for astronomy with a wide spectrum of audiences, from children to professional astronomers, and you’ll occasionally hear his interviews and guest commentaries on National Public Radio and The Weather Channel. He served for a decade on the Board of Directors for the International Dark-Sky Association.

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.

The February Membership Meeting of the Cuyahoga Astronomical Association (CAA) will take place Monday, February 8, from 7:30 to 9:00 p.m. via the Zoom online meeting service.

The evening’s speaker will be Jeff Woytach, retired NASA Scientist whose talk is entitled, “OSIRIS-REx: Mission to Bennu!” OSIRIS-REx is a U.S. mission to return samples from the Near Earth Asteroid Bennu to Earth, and to measure theoretical effects on the asteroid to see how its orbit is perturbed. Bennu is an Earth-crossing asteroid that has the potential to impact our planet. The presentation will talk about the accomplishments of the mission, as well as other sample return missions that have been accomplished or are on the books for the future.

Woytach, originally from Scranton, Pennsylvania, earned a Bachelor of Science in Aerospace Engineering from the Pennsylvania State University in May 1983. He joined the staff of the National Aeronautics and Space Administration’s John H. Glenn Research Center (GRC) in June 1983.

Woytach has worked on space missions launched on the Space Shuttle and the Atlas/Centaur launch vehicle, and on flight hardware for the International Space Station. He is currently the Systems Engineer for the Fission Surface Power System, which will place a nuclear fission reactor on the lunar surface. Mr. Woytach also provides systems engineering support to the Psyche mission.

Led by the Jet Propulsion Laboratory (JPL), Psyche will visit an asteroid believed to be composed entirely of metal. In addition, Jeff is the systems engineer for a small spacecraft being developed to perform ocean research for the National Oceanic Partnership Program. He is also the lead for two university student design competitions sponsored by NASA, involving teams from five U.S. universities In his spare time, Mr. Woytach enjoys space exploration history, collecting space exploration memorabilia, astronomy, and “Star Trek”. He is also the founder of the “Glenn Band,” a concert band comprised of NASA Glenn employees and retirees, their family members and students from the North Olmsted School District. Mr. Woytach and his family are residents of North Ridgeville, Ohio.

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.
