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.

Study finds COVID-19 vaccines prevented 2.5 million deaths worldwide
COVID-19 vaccines prevented an estimated 2,533,000 deaths worldwide between 2020 and 2024, according to an international study led by Università Cattolica del Sacro Cuore in Italy and Stanford University in the United States, published in the journal JAMA Health Forum. Researchers calculated that one death was prevented for every 5,400 doses administered.
The analysis also found that the vaccines saved 14.8 million years of life, equivalent to one year of life gained for every 900 doses given.
The study, coordinated by Professor Stefania Boccia, revealed that 82% of the lives saved were people vaccinated before becoming infected with the virus, and 57% of deaths avoided occurred during the Omicron wave. In addition, 90% of the beneficiaries were adults over 60 years old.
“This is the most comprehensive analysis to date, based on global data and fewer assumptions about the evolution of the pandemic,” explained Boccia and researcher Angelo Maria Pezzullo.

Trump administration blasts judge’s ruling reinstating TPS for Honduras, Nepal, and Nicaragua
The administration of U.S. President Donald Trump criticized a federal judge’s ruling on Friday that reinstated Temporary Protected Status (TPS) for Honduras, Nepal, and Nicaragua, stressing that the immigration program was never intended to serve as a “de facto asylum system.”
On Thursday, Judge Trina Thompson extended protections for about 7,000 Nepalese immigrants, whose TPS was set to expire on August 5. The ruling also impacts roughly 51,000 Hondurans and nearly 3,000 Nicaraguans, whose TPS protections were scheduled to end on September 8.
Immigrants covered by TPS had sued the Department of Homeland Security (DHS), alleging that the program’s termination was driven by “racial animus” and stripped them of protection from deportation.
DHS Deputy Undersecretary Tricia McLaughlin issued a statement saying the decision to end TPS was part of a mandate to “restore the integrity” of the immigration system and return the program to its original purpose.
“TPS was never conceived as a de facto asylum system; however, that is how previous administrations have used it for decades,” McLaughlin emphasized.
She also criticized Judge Thompson, calling the ruling “another example” of judges “stirring up claims of racism to distract from the facts.”
McLaughlin added that DHS would appeal the decision and take the legal battle to higher courts.
The Trump administration has also terminated TPS protections for approximately 160,000 Ukrainians, 350,000 Venezuelans, and at least half a million Haitians, among other immigrant groups.

Trump to build $200M ballroom at the White House by 2028
The U.S. government under President Donald Trump announced on Thursday that it will begin construction in September on a new 8,000-square-meter ballroom at the White House.
The announcement was made by Karoline Leavitt, the administration’s press secretary, during a briefing in which she explained that the expansion responds to the need for a larger venue to host “major events.”
“Other presidents have long wished for a space capable of accommodating large gatherings within the White House complex… President Trump has committed to solving this issue,” Leavitt told reporters.
The project is estimated to cost $200 million, fully funded through donations from Trump himself and other “patriots,” according to a government statement. Construction is scheduled to begin in September and is expected to be completed before Trump’s term ends in 2028.
The Clark Construction Group, a Virginia-based company known for projects such as the Capital One Arena and L’Enfant Plaza in Washington, D.C., has been selected to lead the project.
The new ballroom will be built on the East Wing of the White House, expanding the iconic residence with a space designed for state dinners, official ceremonies, and large-scale events.
