NASA SLS finally Launching Astronaust to the Moon after 50 Years But...SpaceX Starship to Rescue!
The Moon is calling once again!
NASA has just reignited public excitement with the announcement of the first crewed mission to orbit the Moon in over half a century.
Artemis 2’s hardware is set to roll out to the launch pad within two weeks, with the launch window opening on February 6th, 2026.
This marks a remarkable milestone. But behind the celebration lies a challenge Nasa isn’t eager to highlight. The very system designed to carry astronauts back to the Moon faces growing safety and technical concerns that were meant to be resolved long ago.
Enter SpaceX’s Starship that wasn't part of the original plan. Now it's becoming the solution Nasa didn't know it needed.
Find out everything in today's Techmap episode!

Start with the technical issue that delayed Artemis 2 by over a year.
When Artemis 1 flew in November 2022, it was an uncrewed test flight. Orion circled the Moon and returned to Earth. The mission was declared a success. But engineers found something concerning during post-flight inspection.
The heat shield showed unexpected charring and erosion in more than 100 locations. Material that should have ablated smoothly instead cracked and came off in chunks. This happened during reentry at roughly 25,000 miles per hour, when temperatures exceeded 5,000 degrees Fahrenheit.
Nasa spent two years investigating. The root cause turned out to be gas buildup inside the Avcoat material during what's called a skip-entry trajectory. When Orion dips in and out of the atmosphere, then skips back up, gases get trapped and cause the material to crack.
The issue came down to permeability. When Avcoat burns, it produces gas that needs to escape. In this case, it couldn’t. Pressure built up under the surface, breaking the material apart.

Nasa chose not to redesign the heat shield, which would have taken years and added billions in cost. Instead, engineers modified the reentry path for Artemis 2. The new trajectory will produce less heat and reduce internal pressure.
Ironically, another change created part of the problem. Engineers needed clearer ultrasound scans to ensure the heat shield blocks were firmly attached to Orion’s body. The older Avcoat was too porous for accurate scanning, so they made it denser for Artemis 2. That made inspections easier but limited gas escape even further. The revised trajectory can offset that effect by lowering pressure buildup during reentry.
Because the new path narrows timing options, launch opportunities for Artemis 2 are now about half as frequent as before. Where Artemis 1 could launch roughly every 12 days, Artemis 2’s window is now cut by about 50 percent. Nasa officials described the mission as “significantly more difficult” to schedule.
