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.

Venezuela mobilizes forces nationwide as tensions with U.S. rise
Venezuela’s armed forces launched a “massive” nationwide deployment on Tuesday in response to what the government calls “imperialist threats” from the United States, which continues its anti-drug military operation in the region and is preparing for the arrival of its most advanced aircraft carrier.
Since late August, U.S. forces have maintained a growing presence in the Caribbean to combat alleged drug trafficking originating from Colombia and Venezuela. The operation has resulted in the bombing of 20 vessels in international waters in the Caribbean and Pacific, leaving 76 people dead.
Venezuelan authorities claim the U.S. mission is aimed at toppling President Nicolás Maduro. While insisting he seeks peace, Maduro has repeatedly warned the country is prepared to defend itself and has frequently showcased military activities.
A statement from Venezuela’s Defense Ministry said the deployment includes land, air, naval, river and missile systems; armed forces units; the Bolivarian militia; and additional police, military and civilian defense structures.
State broadcaster VTV aired speeches from military leaders in various states, along with images of troops mobilizing and equipment being positioned.
However, analysts note that these frequent and highly publicized announcements do not always lead to visible operations on the ground.
On Monday, Maduro cautioned that Venezuela has the “strength and power” to respond to any aggression, including mobilizing civilians. “If imperialism were to strike and do harm, from the moment the order is given, the entire Venezuelan people would mobilize and fight,” he warned.

Jara: “Real toughness” means targeting drug money in Chile’s crime fight
Left-wing presidential candidate Jeannette Jara said during Chile’s final debate on Monday that the “real tough approach” to crime is to go after the financial networks behind drug trafficking and organized crime.
Rising crime, often linked in public discourse to a surge in irregular migration, has become the top concern among Chileans and has dominated the election campaign.
Although Chile’s homicide rate has nearly tripled over the past decade — from 2.5 to 6.7 per 100,000 inhabitants — the country remains one of the safest in Latin America, according to the United Nations.
“I want to call on the right-wing candidates to join us in targeting those who control the money behind drug trafficking and organized crime. That is real tough action,” Jara, who is favored to win Sunday’s first-round vote, declared during the debate.
All eight candidates faced off on Monday night in the final televised confrontation before the election.
Polls — unavailable since they were suspended on November 2 — indicate that far-right candidate José Antonio Kast is likely to finish second behind Jara, but would hold the advantage in a potential December 14 runoff.
Kast is expected to consolidate support from three other right-wing contenders: Evelyn Matthei, Johannes Kaiser and Franco Parisi.

Investigation widens after Michoacán mayor’s killer shot post-arrest
Mexico’s Security Secretary Omar García Harfuch said Tuesday that the investigation into the killing of a popular mayor from the western state of Michoacán now also includes his security detail. The announcement comes after the governor said the alleged attacker — a 17-year-old — was shot dead after having already been detained.
“The municipal police officers who formed the mayor’s first security ring will give new statements,” García Harfuch said during the president’s daily morning press briefing, noting that includes the officer who admitted firing at the assailant.
He added that authorities are examining both the weapon that killed the attacker and the one that fatally shot the mayor. He did not clarify whether the 14 National Guard members assigned to the mayor’s protection are also under investigation.
Carlos Manzo, mayor of the city of Uruapan, about 400 kilometers west of Mexico City, was gunned down the night of November 1 while surrounded by dozens of people taking part in Day of the Dead festivities.
Governor Alfredo Ramírez Bedolla said Monday that investigators are trying to determine why lethal force was used on the attacker and whether it was excessive. “The killer was detained and moments later there was a struggle and a single shot that killed the assailant,” he said.
Authorities are also reviewing “what happened that led to a lapse or weakening in the mayor’s security cordon,” the governor added, noting that the eight municipal bodyguards were personally chosen by Manzo.
