SpaceX's Starship rocket 38 launches during the 11th test flight on October 13, 2025 as seen from South Padre Island in Texas.
SpaceX said it has pitched NASA a "simplified mission" to put astronauts back on the moon following criticisms over delays by Sean Duffy, the space agency's acting administrator.
In a company blog post out Thursday, Elon Musk's aerospace and defense contractor said: "We've shared and are formally assessing a simplified mission architecture and concept of operations that we believe will result in a faster return to the Moon while simultaneously improving crew safety."
Earlier this month, Duffy said in an interview on CNBC's Squawk Box, that SpaceX was behind schedule on building its lunar landing system for NASA's Artemis III mission and that the agency would reopen the landing contract for that mission to competitors such as Jeff Bezos' rocket maker Blue Origin.
A NASA spokesperson in an email to CNBC said that the agency "has received and is evaluating plans from both SpaceX and Blue Origin for acceleration of HLS production."
"Following the shutdown, the agency will issue an RFI to the broader aerospace industry for their proposals," the spokesperson said. "A committee of NASA subject matter experts is being assembled to evaluate each proposal and determine the best path forward to win the second space race given the urgency of adversarial threats to peace and transparency on the Moon."
NASA had previously said that SpaceX and Blue Origin would have until Oct. 29th to propose new ways to speed up the project.
Musk initially responded to Duffy by posting to his social network X, "Sean Dummy is trying to kill NASA!" In another post, Musk wrote: "The person responsible for America's space program can't have a 2 digit IQ."
SpaceX's massive Starship has flown 11 test flights so far, uncrewed. The last two flights were deemed successful, but the company has not yet shown all the in-orbit refueling capabilities it requires before embarking on the Artemis III, manned lunar mission.
Blue Origin has been developing a lunar lander for NASA and has received about $835 million from the space agency since their contract began in 2023. The company plans to launch a smaller scale version of their lander, known as Blue Moon Mark 1.
