Artemis III Lander Architecture - What Could Still Go Wrong

TL;DR Artemis III is supposed to land two astronauts near the lunar south pole using a stripped-down SpaceX Starship as the Human Landing System (HLS). The architecture is genuinely audacious - it requires a new super-heavy rocket to fly several times before the crewed mission, on-orbit cryogenic propellant transfer at a scale that has never been demonstrated, and a lunar surface stay enabled by a vehicle three times taller than the Saturn V’s lunar module. The technical risk is concentrated in propellant transfer, boil-off management, engine relight reliability, and crew ingress/egress from a 50-metre tower on a sloped, unprepared surface. The schedule risk is concentrated in everything that has to happen before the crewed flight - and most of it has not happened yet. The mission can succeed. The honest read in mid-2026 is that it will succeed late, and the more interesting question is which of these subsystems is actually the long pole. How Artemis III Is Supposed To Work Artemis III’s architecture is not Apollo. Apollo carried everything it needed in one stack on a Saturn V. Artemis III spreads the mission across multiple launches, multiple vehicles, and two distinct propulsion systems, with a crew transfer in lunar orbit. ...

Human Spaceflight Rockets in 2026: A New Era Takes Off

A few weeks ago, four astronauts came home from the Moon for the first time since 1972. Artemis II splashed down on April 11, 2026, after a nine-day flight that took its crew further from Earth than any human has ever travelled - 252,756 miles, a new record set by Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen. It is the clearest signal yet that human spaceflight has stopped being a thing of the past and started being a thing of the near future again. But the headline mission is only one piece of a much larger picture. The decade we are living in is shaping up to be the most consequential one for crewed space travel since Apollo - and unlike the 1960s, this time it is not a single government driving it. ...

Why Spacecraft Don't Just Slow Down Before Reentry

When a spacecraft returns from the Moon, it strikes Earth’s atmosphere at around 25,000 miles per hour. The air in front of it compresses into a glowing plasma sheath hotter than molten lava, and the vehicle effectively becomes a fireball for several minutes. A reasonable question follows - why not just slow down first? Why not fire engines to drop down to something more manageable, like the ~17,500 mph of low Earth orbit, and skip the inferno entirely? ...

What Comes After Artemis: The Road to a Lunar Gateway

The Gateway Concept When most people think of returning to the Moon, they imagine Artemis astronauts landing, collecting samples, and returning home - just like Apollo. That’s the goal for Artemis III and IV. But NASA is building something different for what comes after: the Lunar Gateway. It’s not a destination in itself. It’s infrastructure - a way station in lunar orbit that changes how humans explore the Moon forever. ...

SpaceX Starship vs NASA SLS: Two Visions for Deep Space

Two Paths Diverge The 21st century space race isn’t between countries - it’s between philosophies. NASA’s Space Launch System (SLS) and SpaceX’s Starship represent two radically different bets on how to explore deep space. The SLS is the traditional aerospace approach: specialized hardware, proven technology, massive government investment, and a decades-long development timeline. Starship is the startup approach: rapid iteration, reusability, vertical integration, and “fail fast” in practice. Both are heading to the Moon. Only one philosophy will define deep space exploration beyond. ...

NASA Artemis II

Mission status note: this page includes a time-sensitive status snapshot from April 6, 2026. For live updates, use the official NASA links below and the site tracking page. In Brief Artemis II is NASA’s first crewed mission of the Artemis program and the first time astronauts have traveled toward the Moon since Apollo 17 in 1972. The mission uses NASA’s Space Launch System (SLS) rocket and Orion spacecraft to send four astronauts on a roughly 10-day journey around the Moon and back to Earth. ...

Artemis II: Breaking the Distance Record

As the Orion spacecraft sweeps around the lunar far side, the four-person crew of Artemis II is doing more than just testing hardware - they are venturing further into the cosmos than any human being has ever traveled. Surpassing Apollo 13 For over five decades, the record for the farthest distance humans have traveled from Earth was held by the crew of Apollo 13. In April 1970, due to an emergency “free-return” trajectory, Jim Lovell, Jack Swigert, and Fred Haise reached a distance of approximately 400,171 kilometers (248,655 miles) from Earth. ...
