Final preparations underway for NASA’s Moon rocket launch
| By AFP | Lucie Aubourg |
After two failed attempts this summer, NASA was busy Monday completing final preparations for the launch of its new mega Moon rocket, now scheduled for early Wednesday from Florida.
The Artemis 1 mission, a test flight without astronauts, represents the first step in the US space agency’s plan to build a lasting presence on the Moon, and taking lessons from there to prepare for a future voyage to Mars.
Named after the sister of Apollo in Greek mythology, the new space program comes 50 years after humans last set foot on lunar soil.
The first launch of the Space Launch System rocket, the most powerful ever designed by NASA, is set for Wednesday at 1:04 am local time (0604 GMT), with a possible launch window of two hours.
Countdown has already begun at the storied Kennedy Space Center, where the orange and white behemoth awaits its maiden flight.
The takeoff is scheduled less than a week after the passage of Hurricane Nicole, which the rocket endured outside on its launch pad.
For now, officials are evaluating the risk associated with hurricane damage to a thin strip of caulk-like material called RTV, which encircles the Orion crew capsule atop the rocket, and makes it more aerodynamic.
Teams are looking at whether the RTV could shake loose during launch and pose problems.
Two fallback dates are possible if needed, on November 19 and 25.
But Mike Sarafin, in charge of the Artemis 1 mission, was optimistic Sunday evening. “I feel good headed into this attempt,” he said.
Far side of Moon
The weather promises to be mild, with a 90 percent chance of favorable conditions during the launch window.
At the end of September, the rocket had to be wheeled back to its assembly building to be sheltered from another hurricane, Ian, postponing the mission by several weeks.
Before these weather setbacks, two launch attempts had to be canceled for technical reasons.
The first failure was related to a faulty sensor, and the second to a fuel leak when filling the rocket’s tanks. It runs on ultra-cold, ultra-volatile liquid oxygen and hydrogen.
NASA has since replaced a seal and modified its procedures to avoid thermal shock as much as possible, and succeeded in a tank filling test in late September.
These filling operations are now due to begin Tuesday afternoon, under the orders of Charlie Blackwell-Thompson, NASA’s first female launch director.
About 100,000 people are expected on the coast to watch the launch, with the rocket promising to light up the night sky.
The Orion capsule will be lifted by two boosters and four powerful engines under the core stage, which will detach after only a few minutes.
After a final push from the upper stage, the capsule will be well on its way, taking several days to reach its destination.
Rather than landing on the Moon, it will assume a distant orbit, venturing 40,000 miles (64,000 kilometers) beyond Earth’s natural satellite — further than any other habitable spacecraft so far.
Finally, Orion will embark on the return leg of its journey. When passing through the atmosphere, the capsule’s heat shield will need to withstand a temperature half as hot as the Sun’s surface.
If takeoff happens Wednesday, the mission would last 25 and a half days in all, with a splashdown in the Pacific Ocean on December 11.
NASA is banking on a successful mission after developing the SLS rocket for more than a decade. It will have invested more than $90 billion in its new lunar program by the end of 2025, according to a public audit.
Artemis 2 will be almost a replay of the first mission, albeit with astronauts, in 2024.
Boots on the ground should happen during Artemis 3, no sooner than 2025, with the crew set to include the first woman and first person of color on the Moon.
NASA then wants to launch around one mission per year and build a lunar space station called Gateway. There, humanity must learn to live in deep space and develop the technologies necessary for a round trip to Mars, perhaps in the late 2030s.

Florida judge sets 2027 trial in Trump’s $10 billion lawsuit against BBC
A federal judge in Florida has scheduled February 2027 for the trial in the lawsuit filed by U.S. President Donald Trump against the BBC, in which he is seeking $10 billion in damages for defamation.
Trump accuses the British broadcaster of airing a misleading edit of a speech he delivered on January 6, 2021, which, he says, made it appear that he explicitly urged his supporters to attack the U.S. Capitol in Washington.
The president filed the suit in December in federal court in Florida, alleging defamation and violations of a law governing business practices when the program was broadcast ahead of the 2024 election.
Trump is seeking $5 billion in damages for each of the two claims.
Lawyers for the BBC unsuccessfully asked the court to dismiss the case, arguing that Trump had not suffered a “legally recognizable harm,” since the investigative program Panorama, which included the edited footage, aired outside the United States.

Head-of-state diplomacy key to guiding China–U.S. ties, Beijing says
Head-of-state diplomacy plays an irreplaceable strategic guiding role in China–United States relations, Chinese Foreign Ministry spokesperson Lin Jian said on Thursday during a regular press briefing, when asked about high-level exchanges between the two sides.
Lin added that in a recent phone call, U.S. President Donald Trump once again expressed his intention to visit China in April, while Chinese President Xi Jinping reiterated his invitation.
Both sides remain in communication regarding the matter, the spokesperson said.
Lin noted that the essence of China–U.S. economic and trade ties lies in mutual benefit and win-win outcomes.
“Both parties should work together to implement the important consensus reached by the two heads of state, injecting greater certainty and stability into China–U.S. economic and trade cooperation, as well as into the global economy,” he said.

Trump administration to end special immigration operation in Minnesota
The administration of Donald Trump is bringing to a close its special operation targeting illegal immigration in the northern state of Minnesota, border czar Tom Homan announced Thursday, following weeks of unrest and the fatal shootings of two activists by federal agents.
Thousands of federal officers had been deployed to Minnesota in December to carry out large-scale raids against undocumented immigrants.
The operations triggered strong reactions from residents and advocacy groups, leading to daily confrontations and the deaths of two people who were shot by federal agents.
“I proposed, and President Trump agreed, that this special operation should end in Minnesota,” Homan said during a press conference in the state capital, Minneapolis.
“A significant drawdown began this week and will continue into next week,” he added.
Homan indicated that similar enforcement efforts could be launched in other cities.
“Next week we will redeploy the agents currently here back to their home stations or to other parts of the country where they are needed. But we will continue to enforce immigration laws,” he said.
