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

TL;DR Artemis II splashed down April 11, 2026 - first crewed lunar return since 1972, setting a new distance record of 252,756 miles Crewed rockets in 2026: SLS/Orion, Starship, New Glenn, and China’s Long March 10 - government and commercial programmes running in parallel The Moon is the near-term focus (Artemis III lander race); Mars remains Starship’s long bet Reusability and launch cadence now matter as much as raw lift capacity This decade may be the most consequential for crewed spaceflight since Apollo - but with a different industrial base 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. ...

Why spacecraft don't slow down before reentry - the physics of atmospheric braking

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? ...

The Lunar Gateway - humanity's stepping stone to sustained lunar presence

What Comes After Artemis: The Road to a Lunar Gateway

TL;DR The Lunar Gateway is infrastructure, not a destination: a way station in lunar orbit that separates the hard problem (Earth to lunar orbit) from the repeated one (orbit to surface) Without it, each Artemis landing needs at least two SLS launches plus a Starship - roughly four Moon landings per decade; with it, landings can become routine Assembly is modular: the Power and Propulsion Element arrives around 2028-2029, followed by the HALO habitation module, with operations expanding through the 2030s The Gateway is to the Moon what the ISS is to Earth orbit, and it doubles as a staging point for the lunar far side and eventually deeper space The honest risks are funding uncertainty, lander development, and international coordination - the technology is the more solved part 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. ...

SpaceX Starship vs NASA SLS - two visions for the future of deep space exploration

SpaceX Starship vs NASA SLS: Two Visions for Deep Space

TL;DR SLS and Starship are two bets on the same goal: SLS is the traditional aerospace approach (proven Shuttle-era hardware, simulate everything, launch when confident), Starship is the empirical one (test by launching, iterate fast) The cost chasm is the story: SLS launches are estimated at $2-4 billion each and fully expendable, while SpaceX targets $10 million per launch at scale with full-stack reusability Capability differs less than philosophy - SLS Block 1 lifts 95 tonnes to LEO, Starship 100+ tonnes fully reusable, and both have roles in Artemis SLS looks like a sunset vehicle; Starship is designed as a platform, but it still has to prove orbital refuelling and rapid reuse before the comparison is settled The likely end state is convergence: NASA missions increasingly flown on commercial reusable hardware 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. ...

NASA Artemis II - the first crewed Artemis mission around the Moon

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 human distance record beyond the lunar far side

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. ...
