SpaceX Continues to Lead World in Launch Frequency and Upmass While Starlink Buoys Balance Sheet

Striving to reach 100 launches in 2023, SpaceX has now conducted 61 orbital launches with Falcon-family rockets year-to-date, with ~25 more planned before 2024. This cadence firmly establishes the company as global launch leader for the 2nd year in a row, followed by CNSA, Roscosmos, Rocket Lab and ISRO. In total, Falcon 9 has launched 252 times, with 1 complete and 1 partial failure, while Falcon Heavy has had 7 successful launches. The latest space vehicle designed and built by SpaceX, Starship, is being prepared for its second test launch per CEO Elon Musk – however, FAA clearance remains pending, with Fish and Wildlife Service investigation into 3.5-acre fire started by first launch in April showing significant environmental impact. Starship is to be the lynchpin of the Artemis human return to the Moon, providing the crucial last leg of the journey from Lockheed Martin Orion spacecraft to the lunar surface at a TBD site within 6° of the Moon South Pole NET Dec 2025. SpaceX is also making progress on the financial front, turning a profit (US$55M) in Q1 2023 for the first time in 2 years, due in part to revenue derived from the 1.5M subscribers to Starlink internet service, now available in 60+ nations. 5,027 Starlink satellites have been launched to LEO since May 2019, with 4,652 still functioning in orbit. The constellation is expected to reach 12,000-42,000 total, including Starshield DoD variant.

Focus on Europe: Astrobiology Institute Summer School,  30th Conference of  European Society for Astronomy in Culture

European Astrobiology Institute Summer School will give students hands-on experience learning the role of meteorite, comet impacts in the formation of Earth atmosphere and evolution of life. Session is to take place September 5-14 in town in Nördlingen Ries crater in southern Germany. About 15 million years ago the crater, 25 km in diameter, was created when an asteroid measuring more than a kilometer collided with Earth. Lectures to cover roles of impacts in the formation of habitable planets, physical and chemical properties of comets and meteorites, detection and investigation of impact craters by geological methods and remote sensing from space, ecological consequences of impacts and the role of impacts in mass extinctions. Many instructors from Vienna, Austria participating include Stefan Hölzl (Ries Crater Museum), Ludovic Ferrière (Natural History Museum), and Alexandra Pontefract (Johns Hopkins University). A two-day excursion around the Ries and the smaller Steinheim Crater (40 km to the west) is included. In Warsaw, Poland, the 30th Conference of the European Society for Astronomy in Culture (SEAC) will recognize Nicolas Copernicus at Between Ancient and Modern Astronomy Conference Sep 6-9. Event to explore relationship between astronomy and archeology, cultural, religious, and mythological aspects of civilization. Steven Gullberg (University of Oklahoma) to speak on Cultural Astronomy & Modern Skywatching and Danielle Alexander (University of Wales) speaking on Pleiades as an Avenue for Empathy.
