Earth Day 2024: ESTEC Studies Planetary Protection, MVA Considers Earth-Moon Environmentalism, ESA Astronaut Class Graduates

The 54th Earth Day on April 22 will be marked by protest marches, volunteer cleanups, petition drives, tree plantings and educational events around the world, with ~1B participants in 192 countries. The theme of Earth Day is Planet vs. Plastics, with the goal of eliminating single-use plastics via UN Treaty on Plastic Pollution in 2024 and reducing global plastic (synthetic polymer) production by 60% NLT 2040. Currently, over 400,000,000 tons of plastic is produced annually, impacting wildlife and human health by accumulation and introduction of endocrine-disrupting chemicals into the food chain and water supplies. Concurrently, European Space Research and Technology Centre in The Netherlands will be focusing on a different type of planetary protection – the Near-Earth Object 99942 Apophis, a 340-m asteroid which is to make a predicted 0.00025 AU (37,399.5 km) close approach to our planet on April 13, 2029. Apophis is to be the subject of in-situ analysis during OSIRIS-REx extended mission OSIRIS-APEX days after it passes Earth, the science of which will be topic of workshop Apophis T-5 Years: Knowledge Opportunity for the Science of Planetary Defense. Also on Earth Day, Moon Village Association will ponder expansion of the concept of environment in the space age and how lunar exploration may alleviate anthropogenic climate change with Climate Action & Lunar Exploration virtual panel discussion and ESA will graduate 12 reservists / 5 Astronaut candidates including first Australian Space Agency candidate Katherine Bennell-Pegg.
