Starship reached orbit on its 14th flight, but the 2028 moon landing still waits on three unfinished steps SpaceX's ship circled Earth for the first time on Sept. 28 with an engine out. That settles one requirement for Artemis and leaves the rest of NASA's schedule with little m

A moon suit's hardest job is getting rid of body heat, even next to craters colder than Pluto The lunar surface runs from hotter than boiling water to colder than Pluto. How does one suit keep an astronaut alive across both, and why is the heat inside it the bigger problem?

Artemis 3 astronauts won't enter Starship, even if Orion docks with it Can a moon-lander rehearsal prove enough if the crew never goes inside? The two commercial spacecraft in the mission plan will undergo different tests, with different implications for a lunar landing.

SpaceX's $100 billion spaceport opens after the moon landing it would serve Starbase Louisiana would give Starship 10 pads and its own propellant plant, which is close to what one Artemis landing actually requires. So why is the first launch from it scheduled for 2029?

Is NASA really losing the moon race to China? SpaceX says Starship flies again this month. Government auditors say the moon lander is more than a year late. Both arguments landed within two weeks of each other, so we lined the two countries' own dates up side by side.
