Leonard David's INSIDE OUTER SPACE

The NASA Office of Inspector General (OIG) has released a new report — 2025 Top Management and Performance Challenges.

It outlines five critical challenges facing the Agency:

Challenge 1: Returning Humans to the Moon

Challenge 2: Sustaining a Human Presence in Low Earth Orbit

Challenge 3: Improving Management of Major Programs and Projects

Challenge 4: Managing Cybersecurity Risks and Emerging Technology

Challenge 5: Sustaining Mission Critical Capabilities

Heat shield woes

Regarding the return of humans to the Moon, the newly-issued OIG report notes:

“The most time-sensitive challenge for NASA’s effort to return humans to the Moon is preparing for Artemis II. NASA must address various challenges to safely fly the four astronauts to lunar orbit on their planned 10-day mission,” the report explains.

“While NASA considered Artemis I to be a near-perfect flight, it revealed technical issues that need to be addressed before Artemis II can launch. Specifically, the ablative outer material of Orion’s heat shield did not properly vent the gases normally produced during entry into Earth’s atmosphere, leading to widespread cracking and char loss.”

Root cause

Furthermore, the report explains that “given NASA’s current understanding of the root cause, the Agency intends to reuse the heat shield design for Artemis II while flying a modified reentry trajectory that is less severe.”

High-speed return from lunar distance, the thermal protection system of Orion’s crew module must endure blistering temperatures to keep crew members safe. Measuring 16.5 feet in diameter, Orion’s heat shield is the largest of its kind developed for missions carrying astronauts.

“Although this approach is technically feasible, it is also complex and contingent on a successful test campaign and does not retire the heat shield risk for Artemis III. The additional heat shield testing resulted in cascading delays to all Artemis missions starting with Artemis II.”
