High Hopes for Starship Flight 10, NET August 4 from Starbase

Launch window opens August 4 for Starship test flight 10 from Boca Chica TX for a transatmospheric flight profile similar to the last 3 tests, using Booster 16 and (reportedly) Ship 37. The explosion of Ship 36 caused a considerable delay in the timing of this launch and necessary repairs of the Massey’s test site. The Super Heavy booster will attempt to once again return to Starbase, through a series of boostback and landing burns, and be caught in the Mechazilla launch tower chopstick arms. If Starship is successful in its trajectory, it would splashdown in the Indian Ocean (tests 4, 5, and 6 managed to accomplish this). SpaceX received FAA approval to increase Starship launches to 25 per year from Starbase; for its Falcon 9 rockets, so far 83 have launched this year, and 0 Falcon Heavys. There are at least 11 known Starship flights with specified mission profiles: 4 involving propellant transfers and depots/tankers, the uncrewed Human Landing  System demo mission which will attempt a lunar landing, 5 uncrewed Mars demo missions may launch Q4 2026 and attempt landing mid-2027, and the 2026-27 first commercial Starship carrying the Astrolab Flexible Logistics and Exploration (FLEX) rover with 1,000 kilograms of customer payloads to the Moon surface.

Small Satellite Conference Now in Salt Lake City; Ramping up Lunar Interest

Ice cream socials will continue at the August 10-13, 39th Annual Small Satellite Conference “SmallSat” with theme Reaching New Horizons: New Orbit, Same Mission although the venue for the 1st time is a convention center, the Salt Palace, rather than a college campus. 4,000+ have registered, 1,300+ organizations are represented, 300+ will exhibit, and the ~US$6.4M economic benefit will accrue to Salt Lake City rather than Logan UT. SmallSat provides a platform for discussions on recent successes, emerging technologies and future directions via 2 key tracks, Enterprise and Research & Academia, as well as Posters, Flash Talks, Side Talks and attendees organizing on-site gatherings in free meeting rooms. A trend to lunar orbit subjects is observed with 4 scheduled Enterprise track sessions, 3 Research & Academia seminars, 2 Poster presentations and 3 Flash Talks. A Side Talk on Space Communications Infrastructure will be given by Sean McClinton of RBC Signals, and one titled Lunar: A New Horizon for New Space is by Cristina Conesa of Telespazio Germany will focus on commercialization and economics of operating on the Moon, harvesting lunar resources, and how smallsat companies can transition from Earth orbit to the Moon. A SpaceX representative will present a Rideshare Program update. (Image credits: Small Satellite Conference)
