New launch attempt Saturday for NASA’s Moon rocket
AFP
NASA will make a second attempt to launch its powerful new Moon rocket on Saturday, after scrubbing a test flight earlier in the week, an official said Tuesday.
The highly anticipated uncrewed mission — dubbed Artemis 1 — will bring the United States a step closer to returning astronauts to the Moon five decades after humans last walked on the lunar surface.
Mission manager Mike Sarafin, said the NASA team “agreed to move our launch date to Saturday, September the third.”
Blastoff had been planned for Monday morning but was canceled because a test to get one of the rocket’s four RS-25 engines to the proper temperature range for launch was not successful.
Sarafin announced the date for the new launch attempt during a media briefing on Tuesday, and NASA later tweeted that the two-hour launch window on Saturday would begin at 2:17 pm (1817 GMT).
Launch weather officer Mark Burger said there is a 60 percent chance of rain or thunderstorms on the day of the launch, but added that there is still a “pretty good opportunity weather-wise to launch on Saturday.”
The goal of Artemis 1, named after the twin sister of Apollo, is to test the 322-foot (98-meter) Space Launch System rocket and Orion crew capsule that sits on top.
Mannequins equipped with sensors are standing in for astronauts on the mission and will record acceleration, vibration and radiation levels.
Tens of thousands of people — including US Vice President Kamala Harris — had gathered to watch the launch, 50 years after Apollo 17 astronauts last set foot on the Moon.
Ahead of the planned Monday launch, operations to fill the orange-and-white rocket with ultra-cold liquid hydrogen and oxygen were briefly delayed by a risk of lightning.
A potential leak was detected during the filling of the main stage with hydrogen, causing a pause. After tests, the flow resumed.
NASA engineers later detected the engine temperature problem and decided to scrub the launch.
“The way the sensor is behaving… doesn’t line up with the physics of the situation,” said John Honeycutt, manager of the Space Launch System program, adding that such issues with sensors were “not terribly unusual.”
Sarafin said the team would reconvene on Thursday to assess the situation.
– Orbiting the Moon –
The Orion capsule is to orbit the Moon to see if the vessel is safe for people in the near future. At some point, Artemis aims to put a woman and a person of color on the Moon for the first time.
During the 42-day trip, Orion will follow an elliptical course around the Moon, coming within 60 miles (100 kilometers) at its closest approach and 40,000 miles at its farthest — the deepest into space by a craft designed to carry humans.
One of the main objectives is to test the capsule’s heat shield, which at 16 feet in diameter is the largest ever built.
On its return to Earth’s atmosphere, the heat shield will have to withstand speeds of 25,000 miles per hour and a temperature of 5,000 degrees Fahrenheit (2,760 degrees Celsius) — roughly half as hot as the Sun.
NASA is expected to spend $93 billion between 2012 and 2025 on the Artemis program, which is already years behind schedule, at a cost of $4.1 billion per launch.
The next mission, Artemis 2, will take astronauts into orbit around the Moon without landing on its surface.
The crew of Artemis 3 is to land on the Moon in 2025 at the earliest.
And since humans have already visited the Moon, Artemis has its sights set on another lofty goal: a crewed mission to Mars.
The Artemis program aims to establish a lasting human presence on the Moon with an orbiting space station known as Gateway and a base on the surface.
Gateway would serve as a staging and refueling station for a voyage to the Red Planet that would take a minimum of several months.

Paraguay summons Brazilian ambassador over Itaipú espionage scandal
Paraguay summoned the Brazilian ambassador in Asunción on Tuesday to demand “explanations” and called its own representative in Brasília for consultations following Brazil’s acknowledgment of an espionage operation. The Brazilian government, led by President Luiz Inácio Lula da Silva, attributed the operation to the previous administration.
The surveillance effort aimed to uncover Paraguay’s position in now-suspended negotiations with Brazil regarding the pricing of electricity from the binational Itaipú hydroelectric plant, according to reports in the Brazilian press.
The Brazilian government “categorically denied any involvement in the intelligence operation,” stating in a Foreign Ministry communiqué on Monday that the espionage was carried out under former President Jair Bolsonaro’s administration (2019-2023).
“The operation was authorized by the previous government in June 2022 and was annulled by the interim director of the (state intelligence agency) ABIN on March 27, 2023, as soon as the current administration became aware of it,” Brazil’s government asserted.
Paraguay’s Foreign Minister Rubén Ramírez announced that Brazilian Ambassador José Antonio Marcondes de Carvalho was summoned “to provide detailed explanations” regarding the operation. Additionally, Paraguay recalled its diplomatic representative in Brasília “to report on aspects related to the intelligence activity conducted by Brazil regarding Paraguay’s government affairs.”

Elon Musk to step down as government advisor, per Trump insiders
President Donald Trump has informed his inner circle that Elon Musk will be stepping down from his role as a government advisor, according to a report by Politico today.
Citing three individuals close to Trump, Politico states that the president is pleased with Musk’s leadership at the Department of Government Efficiency (DOGE), where he has implemented significant budget cuts. However, both have agreed that it is time for Musk to return to his businesses and support Trump from a different position outside the government.
A senior administration official told Politico that Musk will likely maintain an informal advisory role and continue to be an occasional visitor to the White House. Another source warned that anyone thinking Musk will completely disappear from Trump’s circle is “deluding themselves.”
According to the sources, this transition is expected to coincide with the end of Musk’s tenure as a “special government employee,” a temporary status that exempts him from certain ethics and conflict-of-interest regulations. This 130-day period is set to expire in late May or early June.

Milei vows to make Argentina so strong that Falkland Islanders “choose” to join
Argentine President Javier Milei reaffirmed his country’s claim over the Falkland Islands (known as the Islas Malvinas in Argentina) and praised the role of the nation’s armed forces during a ceremony marking the “Veterans and Fallen Soldiers of the Malvinas War Day,” commemorating 43 years since the 1982 conflict with the United Kingdom.
Argentina continues to assert sovereignty over the islands, arguing that Britain unlawfully seized them in 1833.
“If sovereignty over the Malvinas is the issue, we have always made it clear that the most important vote is the one cast with one’s feet. We hope that one day, the Malvinas residents will choose to vote with their feet and join us,” Milei stated.
“That is why we aim to become a global power—so much so that they would prefer to be Argentine, making deterrence or persuasion unnecessary. This is why we have embarked on a path of liberation, working to make Argentina the freest country in the world and once again the nation with the highest GDP per capita on the planet,” he added.
