Space Tech Digest — 2026-05-18
SpaceX's Starship V3 megarocket is targeting a Wednesday, May 20 launch for its 12th flight test — the first-ever test of the new V3 design and a critical milestone for NASA's Artemis lunar program. China's Landspace returned to flight with an improved Zhuque-2E methane-fueled rocket, while a basketball-court-sized asteroid made a record-close flyby of Earth today. NASA's Psyche spacecraft executed a dramatic Mars gravity-assist maneuver on its journey to the metal-rich asteroid belt.

Launch & Mission Updates
Starship Flight 12 — Starship V3 Debut
- Vehicle: SpaceX Starship V3 / Super Heavy Booster 19
- Status: Targeted for Wednesday, May 20 launch
- Details: SpaceX is preparing to debut the first-ever Starship V3 configuration in its 12th flight test, launching from Starbase in South Texas. The new design is a prototype of the human landing system NASA intends to use to carry astronauts to the Moon's surface for Artemis III. Stakes are described as "sky-high" — the test must demonstrate capabilities that underpin the entire Artemis moon-landing architecture. A May 19 target was originally reported before slipping one day to May 20.
Landspace Zhuque-2E Return-to-Flight
- Vehicle: Zhuque-2E (methane/liquid-oxygen rocket)
- Status: Launched May 14, 2026
- Details: Chinese commercial launch company Landspace executed a return-to-flight of its improved Zhuque-2E rocket, lofting a mass simulator payload. The Zhuque-2E features "numerous improvements" over previous variants, marking a key step in China's commercial methane-rocket development. A companion Long March 6A launch on the same day lofted a new batch of Qianfan (SpaceSail) broadband constellation satellites.
SpaceX CRS-34 Dragon Cargo — ISS Arrival
- Vehicle: SpaceX Falcon 9 / Dragon cargo capsule
- Status: Launched May 15; en route to ISS
- Details: SpaceX's 34th commercial resupply mission for NASA lifted off on May 15 from Cape Canaveral Space Force Station after a two-day weather delay on May 13. The Dragon capsule carries approximately 6,500 pounds of cargo including new scientific experiments for the International Space Station. The launch occurred in Cape Canaveral sunshine after the scrubbed attempt earlier in the week.
NASA Psyche — Mars Gravity-Assist Flyby
- Vehicle: NASA Psyche spacecraft
- Status: Mars flyby executed (reported ~May 10–11)
- Details: NASA's Psyche spacecraft executed a close flyby of Mars, skimming just 2,800 miles above the planet's surface at roughly 12,000 mph to receive a gravitational slingshot boost. The maneuver saves propellant on Psyche's journey toward the metal-rich asteroid (16) Psyche in the main asteroid belt, and gave mission scientists a rare opportunity to observe Mars with the spacecraft's instruments.
Commercial Space
-
SpaceX (Globalstar): SpaceX wrapped a busy week with a commercial communications launch for Globalstar on Sunday, May 17, carrying nine new satellites to low-Earth orbit from SLC-40 at Cape Canaveral. The mission added to an already dense launch manifest that included the CRS-34 cargo run and Starship Flight 12 preparations.
-
NASA Artemis III Planning: NASA updated its preliminary Artemis III mission plans on May 15, adding design clarifications to the spacer configuration. The update underscores the agency's continued work toward a crewed lunar surface landing, which hinges on a successful demonstration of SpaceX's Starship Human Landing System — the very vehicle targeting its V3 debut flight on May 20.
Science & Discovery
- Asteroid 2026 JH2 — Record-Close Earth Flyby: A newly discovered near-Earth asteroid designated 2026 JH2 — estimated at up to 115 feet (roughly 35 meters) wide, comparable in size to a basketball court or blue whale — safely flew past Earth today (May 18) at a distance of approximately 90,000 km, closer than many operational satellites and well inside the Moon's orbit. The object was only recently spotted, highlighting ongoing planetary defense survey challenges. Observers were able to watch the event live via robotic telescopes in Italy through The Virtual Telescope Project. No threat was posed to Earth.
- NASA HPSC Chip — 500× JWST Computing Power: NASA's Jet Propulsion Laboratory confirmed that a next-generation radiation-hardened processor developed under its High Performance Spaceflight Computing (HPSC) project is now benchmarking at 500 times the computing performance of chips currently running active deep-space missions — including those aboard JWST. The chip is on track for certification by late 2026, targeting readiness for the 2028 crewed Moon landing missions. This leap in onboard processing capability could transform real-time science data handling and autonomous navigation for future deep-space missions.

What to Watch This Week
- Starship Flight 12 (May 20): The first flight of the Starship V3 configuration is the single most important space event of the week. Watch for confirmation of the new design's performance and whether SpaceX can execute booster recovery with Booster 19. Success or failure will directly shape the Artemis III timeline.
- CRS-34 Dragon ISS Docking: The Dragon cargo capsule launched May 15 is approaching the ISS. Watch for docking confirmation and NASA's announcement of science experiments coming aboard.
- Asteroid 2026 JH2 Observations: Now that today's flyby is complete, watch for preliminary scientific data from the Virtual Telescope Project and professional observatories — the close approach provided a rare opportunity to characterize a small near-Earth object at close range.
