Final preparations underway for NASA’s Moon rocket launch

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.

China calls for dialogue amid rising Iran-Israel conflict

The Chinese government emphasized on Monday the importance of “creating the conditions to return to the proper path of dialogue” between Iran and Israel, which have exchanged attacks in recent days resulting in more than 20 Israeli and over 220 Iranian deaths.

Chinese Foreign Ministry spokesperson Guo Jiakun expressed deep concern at a press conference over the Israeli attacks on Iran and the “sudden escalation” of the military conflict.

Guo called on all parties to “take immediate measures to ease tensions and prevent the region from descending into further turmoil,” stating that “force cannot bring lasting peace.”

“If the conflict between Israel and Iran continues to intensify or even expand, the countries of the Middle East will be the first to suffer the consequences,” he added, while noting that China “will continue to maintain communication with the relevant parties, promoting peace and dialogue.”

Chinese Foreign Minister Wang Yi spoke last Saturday with his Iranian and Israeli counterparts to condemn the Israeli airstrike on Iranian territory, which he described as a “violation of international law” with the potential to trigger “disastrous” consequences.

In both calls, Wang reiterated China’s rejection of the use of force, defended diplomacy as the only solution to the Iranian nuclear dispute, and offered China’s mediation to prevent further destabilization in the Middle East.

Suspect arrested in killing of Minnesota legislator and husband, governor Says

Minnesota Governor Tim Walz announced on Sunday the arrest of Vance Luther Boelter, 57, the main suspect in the killing of Democratic legislator Melissa Hortman and her husband in a Brooklyn Park suburb on Friday night.

Boelter, who also reportedly shot State Senator John Hoffman and his wife early Saturday morning, was apprehended in Sibley County following an intensive manhunt involving hundreds of law enforcement officers.

In a public statement, Governor Walz condemned Boelter’s “unthinkable actions,” which resulted in the death of a woman who “shaped the core of who we are as a state.”

“We cannot become numb to this. We are a deeply divided nation,” Walz said in a statement posted on his X account.

“We move forward not with hatred or violence, but with humility, grace, and civility,” he added.

Expressing solidarity with the victims’ families, Walz said the entire state of Minnesota is in mourning. He also thanked law enforcement for their bravery and professionalism: “They have saved lives,” he emphasized.

“As we heal, we will not let fear win,” Walz concluded. “We must honor Melissa by moving forward with understanding, service, and above all, humanity.”

Throughout Sunday, police and sheriff units searched a rural area in Minnesota for Vance Luther Boelter, a security company director and preacher who, according to Governor Walz, acted out of politically motivated violence.

40,000 tourists stranded in Israel amid airspace shutdown over Iran conflict

Approximately 40,000 tourists are stranded in Israel following the closure of the country’s airspace amid escalating hostilities with Iran, the Israeli Ministry of Tourism reported on Monday.

The ministry has set up a virtual office to provide information via email (virtual@goisrael.gov.il) and phone (+972-53-583-5808), as well as a Facebook page called Israel Virtual Tourist Office.

Israeli Tourism Minister Haim Katz is in contact with hotels and accommodations across the country to offer support to tourists in need, the ministry added.

Many stranded travelers are considering crossing overland into Jordan or Egypt to seek flights from those countries. The Israel Airports Authority reminded the public that land border crossings remain open.

Three German tourists stranded in Jerusalem told EFE today that they have not received any assistance from their country’s embassy in Israel, and their primary option currently is to cross into Jordan to catch a flight from there.

Since early Friday morning, Israel launched operations against Iran, targeting military personnel and infrastructure, including energy and nuclear facilities, as well as numerous residential areas in Tehran.

In response, Iran has fired hundreds of ballistic missiles at Israel, some of which have struck various locations across the country, leaving at least 24 dead so far, according to Israeli authorities.

Iranian health officials report at least 224 deaths, mostly civilians, including at least 17 senior military officials—nine from the Revolutionary Guard—and more than a dozen nuclear scientists.

The Israeli military has warned that many more “targets” remain, while Iran’s Revolutionary Guard declared on Monday that it will continue missile attacks against Israel until its “destruction.”
