SpaceX's Big Design Dragon Heat Shields Upgraded to the Moon Instead of NASA Orion...
Artemis 1 was a big success for NASA back in December 2022, which marked a major step forward in lunar exploration.
But it also faced serious challenges. Orion’s heat shield suffered unexpected damage after its trip around the Moon, and the launch pad was heavily impacted.
NASA’s two-year investigation led to a debated choice to keep the Avcoat material, which pales against SpaceX’s Crew Dragon heat shield, proven in over 50 missions.
This raises serious concerns about the safety of the Artemis II crew and puts Dragon in the spotlight as a potential alternative to replace Orion for the mission.
So, what’s really happened so far?
Let’s dive into all the details in today’s episode of Tech Map.

On December 11th, 2022, everything aligned perfectly for Orion’s homecoming. The spacecraft had just completed an extraordinary journey, marking the successful end of the Artemis I mission.
After spending 25 days in space, gliding around the Moon at altitudes as low as 130 kilometers and conducting a wide range of experiments, Orion plunged back through Earth’s atmosphere and made a safe splashdown in the Pacific Ocean, near Guadalupe Island, just off the coast of California, precisely at 12:40 PM.
The moment sent waves of emotion through space enthusiasts around the world. Cheers echoed throughout NASA as the team realized they had just achieved a flawless first step in the Artemis program.
It was hailed as “a historic day” and “a major leap forward” for the future of lunar exploration.
But behind all that joy… was a stack of serious problems that needed fixing fast.

During the launch, Launch Pad 39B took some serious damage.
The 8.8 million pounds of thrust and crazy high heat from the 4 main RS-25 engines plus the two side boosters did a number on it.
Some elevator doors on the launch tower got blown off or dented from the pressure and shockwaves. The water deluge system lost a few spray nozzles. The pad surface was badly scorched.
A bunch of cables connecting the tower to the ground systems got damaged too. And that’s just part of it, NASA had a lot of fixing to do afterward.
When inspecting the site, managers found two small objects near the pad that shouldn’t have been there: some ""throat plug material"" expelled from the rocket at liftoff (which happens fairly often with launches), and a piece of RTV, the insulating sealant, that came loose from the base of the Orion capsule.
