NASA's return to the Moon
The Artemis program is NASA's flagship effort to return humans to the lunar surface, targeting the first woman and person of color on the Moon. Built on the SLS rocket, Orion capsule, and Lunar Gateway space station, Artemis represents a new era of sustained lunar exploration. International partners including ESA, JAXA, and CSA are contributing key elements to this multi-mission campaign.

Inside Chandrayaan-4, India's ambitious lunar sample-return mission — five modules, two LVM3 launches, orbital docking, and about 3 kg of Moon rock by 2028.
Space History
From Project 921 and Yang Liwei's 2003 first flight to Tiangong crew rotations, the Mengzhou spacecraft and a 2030 Moon landing — the Shenzhou story.

Boeing's Starliner flew two astronauts to the ISS in 2024 but came home empty. What went wrong with its thrusters, how the crew got back, and what comes next.
Space Exploration
China's Tianwen-2 reached the quasi-moon Kamoʻoalewa in June 2026 to grab an asteroid sample, return it to Earth by 2027, then chase a comet.
Space Science
Side-by-side: Roman, Hubble, JWST, and Euclid compared on mirror size, field of view, wavelength, orbit, and science goals — with a full comparison table.

On May 28, 2026, a New Glenn static fire anomaly levelled Launch Complex 36. Here's what it means for Blue Moon, Artemis 3, and NASA's 2028 moon landing.
Space Exploration
NASA's $749M Moon Base Phase One — Astrolab CLV-1 and Lunar Outpost Pegasus rovers, Blue Moon Mk1 LTV delivery, and Firefly's MoonFall hopper drones.
analysis
SpaceX has roughly $22 billion of lifetime federal commitments, $3.8 billion in FY2024 obligations, and a 100% sweep of NSSL Phase 3 Lane 1 task orders awarded through May 2026. The bull case is that this concentration is the moat. The bear case is that this concentration is the tail risk. We build the full contract stack, walk the audit trail, and weigh the political volatility that bracketed June 2025.
analysis
Starship is the single most consequential variable in the SpaceX SOTP. The marketed economics — $20-30M per launch, $100-200/kg to LEO — would re-base the entire space economy. The probable economics through 2028 are different. We build the model, weigh HLS execution risk, and explain why the Mars architecture is the most over-discussed and least near-term-relevant part of the thesis.

Why a Seattle startup just won a NASA contract to extract helium-3 from lunar regolith — and whether the fusion-fuel argument actually holds up to scrutiny.
