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.

Heat wave puts more than 70 million Americans under alerts as temperatures near 46°C
More than 70 million people remained under heat alerts Monday as an intense heat wave continued across the southern United States, particularly Florida and states along the Mexican border, where temperatures and heat indexes could reach as high as 46 degrees Celsius, according to the National Weather Service (NWS).
Several cities recorded or tied temperature records over the weekend and into Monday, including Miami and Fort Lauderdale in Florida; Laredo, Borger and Austin’s airport in Texas; Atlanta, Georgia; Raleigh and Charlotte, North Carolina; and Memphis, Tennessee.
The NWS warned that the heat wave will continue affecting the southern and southeastern United States, with maximum temperatures expected to remain near 38°C to 40°C for several days. The heat index, which combines temperature and humidity to estimate how hot conditions feel, could reach 46°C.
The extreme heat is also spreading into the Southwest, where temperatures began rising again between Monday and Tuesday. Forecast highs in the region range from about 38°C to 43°C.
Heat alerts remain in effect across Nevada, Arizona and California, including areas in southern Arizona and California near the Mexican border, as authorities warn of the risks posed by prolonged extreme temperatures.
The NWS urged residents to limit outdoor activity, stay hydrated, ensure access to air conditioning or cooling centers, and check on vulnerable friends, neighbors and family members.
The United States is experiencing a summer marked by above-average temperatures and repeated heat waves. One of the most intense episodes occurred during the July 4 weekend, when extreme heat was blamed for roughly 30 deaths.
July was the hottest month ever recorded in the United States since measurements began, with the average temperature across the contiguous country approaching 25°C, according to the National Oceanic and Atmospheric Administration (NOAA).
The combination of extreme heat and drought conditions has also fueled wildfires. Nearly 3 million hectares have burned across the country so far in 2026, making it the largest area affected by wildfires in a decade.

Trump warns Iran over nuclear ambitions as U.S.-Iran ceasefire deadline passes
U.S. President Donald Trump reiterated Monday that Iran must never be allowed to obtain a nuclear weapon, as a 60-day deadline set under a memorandum of understanding between Washington and Tehran expired without an agreement to end the conflict in the Middle East.
“The number one goal is, and always will be, that Iran cannot have, in any way or under any circumstances, a nuclear weapon,” Trump wrote in a post on his Truth Social platform.
The memorandum, signed on June 17, called for an “immediate and permanent cessation of military operations on all fronts” as part of a broader negotiation process aimed at ending the conflict. However, the deadline expired Monday without a peace agreement, while both Washington and Tehran continued to maintain their respective positions.
The expiration is largely symbolic, as military clashes resumed during the 60-day period. The Strait of Hormuz also remains blocked, contributing to elevated global oil prices.
Trump escalated his rhetoric toward Tehran last Friday, saying he planned to declare the Strait of Hormuz U.S. territory after defeating Iran.
“After we finish defeating Iran, which is being very badly defeated, very soon I will essentially declare the Strait of Hormuz U.S. territory,” Trump said during a political rally in Long Island, New York. He also claimed that the United States currently controls the passage of vessels through the strategic waterway.
Meanwhile, U.S. Treasury Secretary Scott Bessent said Washington is preparing additional economic measures against Iran that he described as unprecedented.
“Stay tuned for new announcements next week because we are going to implement measures unlike anything ever seen in the history of the economic isolation of a country,” Bessent said.
The Treasury secretary indicated that the measures would form part of a broader “double hit” strategy that could also involve maintaining the blockade of Iranian ports.

Brazil’s Lula and Flávio Bolsonaro kick off election campaigns amid focus on crime
Public security took center stage Sunday as Brazilian President Luiz Inácio Lula da Silva and Senator Flávio Bolsonaro formally launched their election campaigns, positioning themselves as the leading rivals ahead of the October presidential vote.
Lula, who leads most opinion polls, kicked off his campaign at the Vila Euclides stadium in São Bernardo do Campo, in São Paulo state, while Bolsonaro held his event in Rio de Janeiro, a political stronghold of his family.
During his speech, Lula announced plans to create a new Ministry of Public Security aimed at strengthening coordination between the federal government and Brazil’s states in the fight against crime.
The president pledged a tougher strategy to reclaim territories controlled or influenced by criminal groups. The proposed ministry would help “share responsibilities with the states” and confront those who seek to control favelas and impoverished neighborhoods, Lula told supporters.
The initiative places public security at the heart of Lula’s campaign as he seeks another term in office amid persistent concerns over crime and organized criminal activity in Brazil.
Lula also used his first campaign speech to reinforce his position as a leading figure of Brazil’s left and to criticize his political opponents on the right.
“I will not allow the right to take power,” Lula said, accusing his opponents of having previously mocked children who died because they lacked access to medicine.
“I don’t know what future these people imagine for the Brazilian people,” he added.
