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.

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.

U.S. to Limit Visa Duration for Foreign Students and Journalists
The United States has announced new limits on the legal length of stay for foreign students and journalists, marking the latest tightening of immigration policies under President Donald Trump.
The changes, outlined in an administrative rule published on Thursday, are expected to take effect in September, unless Congress blocks the measure.
Under the new policy, holders of student visas will be allowed to remain in the United States for no more than four years.
Foreign journalists will be limited to 240-day stays—approximately eight months—with the possibility of applying for extensions of the same duration.
The policy imposes even stricter rules on Chinese journalists, whose visas will be capped at 90 days.
More than 100 international news organizations and press freedom groups, including Agence France-Presse (AFP), criticized the measure in an open letter, arguing that it would reduce both the quantity and quality of international coverage of events in the United States.
The Republican Party, led by President Trump, currently holds a majority in Congress and has pledged to curb both illegal immigration and certain forms of legal immigration.
Previously, the United States generally issued student visas for the full duration of an academic program, while foreign journalists could receive visas valid for up to five years.

Nicaragua Cuts Diplomatic Ties With Italy Over Red Brigades Dispute
The Nicaraguan government announced on Thursday that it is severing diplomatic relations with Italy following criticism from the Italian government over Nicaragua’s long-standing decision to shelter Alessio Casimirri, a former member of the Red Brigades convicted in Italy for the 1978 kidnapping and murder of former Prime Minister Aldo Moro.
Italian Foreign Minister Antonio Tajani criticized the administration of co-presidents Daniel Ortega and Rosario Murillo on Wednesday for continuing to provide refuge to Casimirri, who was sentenced in Italy to six life terms for his role in Moro’s abduction and killing.
In a statement issued Thursday, Nicaragua’s Foreign Ministry said it was ending all diplomatic relations with Italy, describing Tajani’s remarks as “unjustified, aggressive, and irresponsible.”
Tajani made the comments during a gathering of conservative leaders from Europe and Latin America held in Madrid.
“We have absolutely nothing in common with the positions of extremist governments such as Nicaragua, a country that continues to harbor dangerous Red Brigades terrorists like Alessio Casimirri,” Tajani said, according to Italian media.
The diplomatic break marks a new escalation in tensions between the two countries over the decades-old case involving Casimirri, who has lived in Nicaragua for many years despite repeated calls from Italy for his extradition.

U.S. Strikes Hit Areas Near Strait of Hormuz as Tensions With Iran Escalate
Several U.S. strikes targeted areas near the Strait of Hormuz on Thursday, according to Iranian state media citing local authorities, as hostilities between the United States and Iran intensified.
Officials in Iran’s Hormozgan Province said the island of Qeshm was struck multiple times by what they described as U.S. missiles during the evening. The reports were carried by the Iranian news agencies Fars and Tasnim.
Iranian state television also reported that the Bandar Abbas region, located on the Iranian coast overlooking the Strait of Hormuz, was the target of what authorities described as an “enemy U.S. air attack.”
According to local officials quoted by state television, no casualties have been reported following the strikes.
The reported attacks come amid renewed military tensions between Washington and Tehran, although U.S. authorities had not immediately commented on the reported operations.
