NASA Plans Lunar Orbit Mission to Launch Astronauts by March 6th

NASA is set to launch four astronauts on the highly anticipated Artemis II mission, scheduled for March 6. This groundbreaking flight will take astronauts around the moon, marking a historic return to lunar exploration.

The launch date was confirmed after NASA successfully filled the Space Launch System (SLS) rocket with over 700,000 gallons of cryogenic propellant and completed a comprehensive refueling test. This test simulated nearly every countdown step and launch-day procedures.

A successful wet dress rehearsal indicates that astronauts could be just two weeks away from visiting the moon for the first time in over half a century.

The Artemis II mission will be historic, as it will be the first time NASA’s Space Launch System rocket and Orion capsule carry humans. The mission is set to last 10 days, during which astronauts will journey farther from Earth than any humans have ever traveled.

Thursday’s extensive refueling test signaled significant progress for NASA. This was the second attempt at a wet dress rehearsal; the first was halted on February 2 due to a hydrogen fuel leak detected in the rocket’s rear. This issue led mission managers to abandon all launch windows for February.

Lori Glaze, acting deputy administrator for NASA’s Exploration Systems Development Mission Directorate, emphasized that the March 6 launch depends on completing necessary work on the launch pad and the thorough evaluation of the wet dress rehearsal results.

The mission team plans to hold a flight readiness review next week, where NASA managers and executives will officially certify the rocket and spacecraft for flight.

“Everything is set in front of us,” Glaze stated at a press conference on Friday. “If we can get through these final preparations, we are in a strong position to target March 6.”

In the interim between the first and second wet dress rehearsals, engineers addressed earlier leaks by replacing two seals in the fuel supply line and conducting repairs and tests on the launch pad. Artemis launch director Charlie Blackwell-Thompson reported that the seals are now “rock solid” after the recent repairs.

“Overcoming this wet dress rehearsal milestone was crucial for our progress,” she noted.

The Artemis II crew consists of NASA astronauts Reed Wiseman, Christina Koch, Victor Glover, and Canadian astronaut Jeremy Hansen. While they did not participate in the wet dress rehearsal, several crew members were present at Kennedy Space Center, Florida, during the test.

“I had the opportunity to speak with Reid Wiseman, Christina Koch, and Jeremy Hansen,” Glaze shared. “They are extremely enthusiastic about the possibility of a March launch.”

To ensure their health ahead of the mission, the astronauts will undergo quarantine in Houston starting Friday afternoon. They will arrive in Florida about five days before the launch and continue their pre-flight quarantine at Kennedy Space Center.

Live coverage of SpaceX’s 6th test flight with appearances by Musk and Trump

SpaceX is gearing up for the sixth test flight of Starship, the world’s most powerful rocket. Elon Musk’s company follows a “fail fast, learn fast” approach to research and development, which resembles the culture of Silicon Valley more than the aerospace industry, with an acceleration in the pace of launches. It seems so.

When is the next flight?

SpaceX states on the website that Starship is scheduled to conduct its sixth test flight on November 19th, with launch slots opening at 4pm Central Time (10pm UK). A live stream of the launch will be available. SpaceX’s X account on the social media platform also owned by Musk, can be viewed here at newscientist.com

It took SpaceX 18 months to complete Starship’s first five test flights, with the fifth happening in mid-October. With the launch of its sixth flight next week, it will be just over a month since the last flight, making it the fastest flight yet.

What will SpaceX attempt with Flight 6?

Flight 6 mirrors Flight 5 in many ways but with some significant differences.

The booster stage will once again try a “chopstick” landing, catching and securing the vehicle as it returns to the launch pad for a soft landing. This methodology aims to eventually enable boosters to be reused multiple times, significantly reducing the cost of launching payloads into orbit.

The upper stage will enter space, complete a partial orbit, re-enter Earth’s atmosphere, and splash-land in the Indian Ocean. In this flight, the upper stage will attempt to reignite one of the Raptor engines in space to gather valuable operational data. Also, new heat shield designs will be tested during atmospheric reentry.

One notable change in this flight is that the landing of the upper stage in the Indian Ocean will be filmed during the day as the launch occurs later in the day. This will provide detailed images as previous landings happened at night, limiting the visibility for engineers compared to daytime landings.

What occurred in previous Starship launches?

During the first test flight on April 20, 2023, three out of the 33 engines in the booster stage failed to ignite. This led to the rocket becoming uncontrollable and self-destructing.

In the second test flight on November 18, 2023, the flight proceeded further, with the booster and upper stage separating as planned. However, the booster stage exploded before reaching the ground, and the upper stage self-destructed before reaching space.

Test Flight 3 on March 14, 2024, was at least partially successful as the upper stage reached space, but it did not return to Earth unscathed.

The subsequent flight on June 6 saw the upper stage reach an altitude of over 200 kilometers and fly at speeds exceeding 27,000 kilometers per hour. Both the booster and upper stage completed a soft landing at sea.

Test Flight 5 was the most ambitious yet, with Starship’s super-heavy booster touching down on the launch pad and being safely caught by “chopsticks” on SpaceX’s launch tower, known as Mechazilla. This innovative landing approach aims to secure and lower the booster for reuse.
