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.

Senate Bipartisan Vote Moves Measure to Block Further U.S. Military Action in Venezuela
The U.S. Senate took a significant step on Thursday toward limiting President Donald Trump’s military authority in Venezuela, advancing a bipartisan war powers resolution that would block further military actions without explicit congressional approval, lawmakers said.
In a 52-47 procedural vote, the measure moved forward after five Republican senators joined all Democrats in supporting the effort. The resolution aims to require presidential authorization from Congress before the United States can engage in any new hostilities against Venezuela, a rare rebuke of Trump from both sides of the aisle following the controversial military operation that resulted in the capture of Venezuelan leader Nicolás Maduro.
If ultimately passed, the legislation would obligate the administration to withdraw U.S. forces from any imminent hostilities in or against Venezuela unless Congress explicitly authorizes such actions. However, the measure’s future remains uncertain as it heads next to the House of Representatives, where a Republican majority is less likely to approve it, and any final version would likely face a presidential veto. Overriding a veto would require a two-thirds majority in both chambers, a high threshold in the current political landscape.
President Trump has sharply criticized Republican senators who broke ranks to support the resolution, saying they should not be re-elected and arguing that the measure undermines his authority to act in national defense. Nevertheless, the vote signals growing bipartisan concern in Congress about unchecked executive military action in the absence of legislative authorization.

Petro and Trump Agree on Joint Action Against ELN Guerrillas After Tense Diplomacy
Colombian President Gustavo Petro and his U.S. counterpart Donald Trump agreed on “joint actions” to combat the National Liberation Army (ELN) guerrilla group operating along the Colombia–Venezuela border, Colombia’s Interior Minister Armando Benedetti said on Thursday.
The announcement came after a period of heightened diplomatic tension triggered by recent U.S. airstrikes in Venezuela, the capture of Venezuelan President Nicolás Maduro, and threats of possible U.S. military action in Colombia. The phone call Wednesday evening was the first direct conversation between Petro and Trump since both leaders took office, and it helped ease the strained relationship.
During the call, both presidents committed to carry out joint efforts against the ELN, a guerrilla group that has repeatedly attacked Colombian security forces and is accused of kidnapping soldiers. In December, the ELN declared a “armed strike,” confining civilians in areas under its control in response to perceived threats of U.S. intervention.
According to Benedetti, Petro welcomed Trump’s invitation to meet in Washington and asked for U.S. support to “strike hard” against ELN positions along the porous border with Venezuela, where guerrillas often flee after clashes with Colombian forces.
The border region is a longstanding flashpoint, where armed groups, drug traffickers and illegal mining networks compete for control. Previous attempts by Petro’s government to negotiate peace with the ELN have stalled after a major offensive in Catatumbo that left hundreds dead and displaced thousands.

Lula Vetoes Bill That Would Have Shortened Bolsonaro’s Prison Sentence
Brazilian President Luiz Inácio Lula da Silva vetoed on Thursday a bill that would have significantly reduced the prison sentence of his far-right predecessor, Jair Bolsonaro, who is currently serving time for attempting a coup d’état.
Despite the veto, the conservative-majority Congress retains the power to override the decision through a vote.
In September, following a landmark trial, Brazil’s Supreme Court sentenced Bolsonaro to 27 years in prison after finding him guilty of conspiring to remain in power in an “authoritarian” manner following his defeat to Lula in the 2022 presidential election.
The 70-year-old former president has been incarcerated in a Brasília prison since late November. Earlier this month, the Supreme Court rejected a request for house arrest on health grounds.
Under the current legal framework, Bolsonaro would be required to serve approximately eight years before becoming eligible for sentence leniency. However, a bill passed by Congress in December could have reduced that period to just over two years, prompting Lula’s veto.
