NASA postpones the next Artemis flights much more

Published

on

NASA has postponed the first crewed landing of the program until mid-2027, delaying the following two Artemis trips to the moon.

After identifying the primary cause of Orion heat shield erosion on the Artemis 1 mission two years ago, NASA leadership announced at a news conference on December 5 that they were postponing the Artemis 2 and 3 flights.

Artemis 2, which was originally planned to launch in September 2025, would now debut in April 2026 under the updated schedule. It will be the first crewed voyage of Orion to take four astronauts from the United States and Canada around the moon.

As a result, Artemis 3, which will use SpaceX’s Starship vehicle for the first crewed landing of the entire exploration effort, will be delayed. Originally scheduled for September 2026, that mission is now anticipated to occur in mid-2027.

Following an examination of Artemis 1’s heat shield deterioration, NASA changed that timeline. In October, agency representatives claimed to have identified the cause of the heat shield material’s release, but they did not elaborate on the cause or NASA’s plans to fix it.

NASA Deputy Administrator Pam Melroy said the issue was related to Orion’s “skip” reentry, in which the capsule enters and exits the atmosphere to release energy. In the outer layers of the heat shield, more heat was retained than anticipated, resulting in trapped gases. “This caused internal pressure to build up and led to cracking and uneven shedding of that outer layer,”  she said.

This judgment was confirmed by an independent review panel after a thorough study. “There were a lot of links in the error chain that accumulated over time that led to our inability to predict this in ground tests,” stated Amit Kshatriya, deputy assistant administrator of NASA’s Moon to Mars Program Office. This included modifications to the shape of the material blocks and modifications to the manufacturing process of the heat shield material, known as Avcoat.

He said that in areas of the Avcoat material with the required greater permeability to let the gasses out, that was verified. “In those places, we did not witness in-flight cracking, and that was the key clue for us.”

NASA will alter the reentry profile, including shortening the skip phase of the reentry, rather than replacing the entire heat shield for the Artemis 2 mission. According to ground tests, those adjustments should be enough to prevent material from breaking off as a result of cracking.

The agency has been working on a number of other Orion issues while looking into the heat shield issue, such as a battery issue that was reported in January but was reportedly fixed, according to Kshatriya.

Despite an upcoming presidential transition that would probably rethink the entire Artemis design, agency chiefs said they made the decision immediately to prevent future delays. “We’re on a day-for-day slip. We had to make this decision,” Melroy stated. “If you’re waiting for a new admininstrator to be confirmed and a team to come up to speed on all this technical work we’ve all been tracking very closely, I think that would be actually far worse.”

Shortly after President-elect Donald Trump stated on December 4 that he would select Jared Isaacman to oversee the agency, NASA Administrator Bill Nelson claimed he spoke with Isaacman. He did, however, add that he and other authorities had a discussion prior to the meetings in which they confirmed the revised plan for Artemis 2 and 3. Melroy went on to say that NASA could have been consulted on the decision, but the incoming administration has not dispatched a transition team there.

Nelson, however, maintained that the present architecture was still the most effective way to send humans back to the moon in spite of the problems and delays, pointing out that even with the most recent postponement, NASA would still make a lunar landing before China’s projected 2030 lunar mission.

“Are they going to axe Artemis and insert Starship?” In reference to the impending Trump administration, Nelson stated. Only Orion is rated for human spaceflight outside of Earth’s orbit, he said. “I expect that this is going to continue.”

NASA’s JPL Set to Resume Normal Operations After L.A. Fires

NASA’s Jet Propulsion Laboratory (JPL) is preparing to return to regular operations following disruptions caused by the Eaton Fire, which impacted areas near Los Angeles.

Located at the base of the San Gabriel Mountains, JPL faced threats from the fire, which has heavily affected nearby communities like Altadena. The lab, known as NASA’s primary hub for planetary exploration, has been closed since January 8, except for essential activities like managing the Perseverance and Curiosity Mars rovers and other critical missions.

With the Eaton Fire no longer posing a direct threat, JPL plans to reopen next week.

“From Tuesday, Jan. 21 through Jan. 24, 2025, the lab will be accessible to any personnel who need to work on-site. Personnel able to telework are encouraged to do so as the facility undergoes full and final cleanup,” JPL officials stated on their emergency information site on Friday, Jan. 17.

The fire’s impact has been severe, with widespread damage in the community. “Significant devastation in our community. 1,000 still evacuated. More than 150 homes completely lost, and many others will face long-term displacement,” JPL Director Laurie Leshin shared in a post on X on Jan. 10.

In a subsequent post, Leshin provided a link to a disaster-relief fundraising site aimed at supporting JPL employees and staff from the California Institute of Technology in Pasadena, which manages the facility for NASA.

The Eaton Fire has burned 14,117 acres (5,713 hectares) so far and is now 65% contained, according to NBC News. Meanwhile, the larger Palisades Fire has scorched 23,713 acres (9,596 hectares) and remains just 31% contained, making it the most destructive of the recent L.A. fires.

SpaceX will begin a busy year for moon missions this week with the launch of two private lunar landers

SpaceX will begin a busy year for moon missions this week with the launch of two private lunar landers

A busy year of lunar missions will begin this week with the launch of two private lunar landers on the same rocket.

The SpaceX Falcon 9 rocket that will launch the missions has a six-day window starting early Wednesday morning (Jan. 15). Liftoff from Launch Complex-39B at NASA’s Kennedy Space Center (KSC) in Florida is set for 1:11 a.m. EST (0611 GMT).

Both landers will be transported by Falcon 9 to Earth orbit, where they will start separate journeys to the moon. The goal of Firefly Aerospace’s Blue Ghost Mission 1 lunar lander, Ghost Riders in the Sky, is to transport scientific payloads to the moon’s surface as part of NASA’s Commercial Lunar Payload Services (CLPS) program. Resilience, the second lander, is the second mission that the Japanese corporation ispace has undertaken in an attempt to land on the moon. Blue Ghost will be followed by iSpace’s Mission 2, which will take almost four times as long to finish.

In order to set its course toward the moon, Blue Ghost will orbit the Earth for 25 days before an engine fire. If all goes according to plan, the lander will autonomously land in Mare Crisium (“Sea of Crises”) after another 20 days, which includes 16 days in lunar orbit and four days in transit, to start two weeks of lunar science.

About five hours after nightfall on the lander’s site, Blue Ghost’s 60-day journey from Earth to the moon would come to an end. Before shutting down, the spacecraft will use its remaining battery power to take a picture of the lunar sunset.

After launch, the Resilience lander is expected to settle four to five months later on a significantly slower trajectory. Based on the lessons acquired during Hakuto-R Mission 1, ispace’s second mission, Resilience, has been outfitted with both software and hardware enhancements. In April 2023, the mission’s attempt to land was unsuccessful due to a malfunctioning altitude sensor on the lander, which caused a crash on the lunar surface. The mission had successfully reached lunar orbit.

With Hakuto-R Mission 2, ispace is adopting a methodical approach, outlining a 10-step list of milestones Resilience will accomplish en route to the moon, along with an additional checklist for objectives accomplished after a successful lunar landing. In the northern hemisphere of the moon, the lander is headed for Mare Frigoris (Sea of Cold), where it will start surface operations. As part of a contract with NASA, the lander will deploy an onboard microrover called Tenacious to gather a sample of regolith, or moon dust.

Future months will see more moon missions

Another lunar laundering operation, this time from the only private corporation to land on the moon so far, will follow this week’s Falcon 9 mission to the moon in a short period of time.

In February 2024, Intuitive Machines launched Odysseus, its first Nova-C lander, carrying six NASA CLPS payloads along with six additional commercial payloads. Odysseus made a largely successful landing on that mission, called IM-1, close to the crater Malapert A, which is roughly 190 miles (300 kilometers) from the lunar south pole.

IM-2 is scheduled to launch in February and will similarly travel to the south pole area of the moon, namely to a ridge close to Shackleton Crater. Among the several CLPS payloads that IM-2 will transport for NASA is an experiment known as PRIME-1 (Polar Resources Ice Mining Experiment-1), which will assist in verifying the region’s water ice abundance.

Later in 2025, a third Nova-C lander is scheduled to fly on the IM-3 mission, bringing another round of CLPS experiments and technology demonstrations on the lunar surface for the space agency.

Another probe carrying NASA CLPS payloads, Griffin Mission One, is another project that Pittsburgh-based startup Astrobotic is aiming for this year. A fuel leak prevented the company’s Peregrine lunar lander from reaching the moon after it launched last year. The probe was instead returned to Earth by its handlers, where it burned up during atmospheric descent over the Pacific Ocean.

The goal of NASA’s several CLPS contracts is to advance the agency’s Artemis program, which intends to send humans to the moon in 2027 and eventually establish a base in the southern polar area of the moon, where water ice seems to be abundant. NASA gave Human Landing Services (HLS) contracts to businesses to transport astronauts to the moon’s surface, much like CLPS did. In 2025, SpaceX’s Starship rocket—which was awarded NASA’s first HLS contract—is anticipated to do dozens of test flights, maybe including one around the moon.

By using its Blue Moon lander to transport humans to the lunar surface for missions beyond Artemis 3, Blue Origin was awarded NASA’s second HLS contract.Blue Origin’s MK1 Lunar Lander pathfinder mission is on track for a potential 2025 launch after the company’s New Glenn rocket launched successfully on January 12.

ISS astronauts send Christmas greetings to Earth

Published

on

Surrounded by floating candy canes and a snowman crafted from stowage bags, astronauts aboard the International Space Station (ISS) came together to share holiday greetings with those on Earth.

Expedition 72 commander Sunita “Suni” Williams, wearing festive reindeer antlers, joined fellow NASA astronauts Barry “Butch” Wilmore, Don Pettit, and Nick Hague in a cheerful video message from 260 miles (420 kilometers) above the planet.

“This is a wonderful time of year up here,” said Williams in the recording made on Monday, December 23. “We’re spending it with our space family—there are seven of us aboard the International Space Station—enjoying each other’s company.”

In addition to the four NASA astronauts, the ISS crew includes Alexey Ovchinin, Ivan Vagner, and Aleksandr Gorbunov from Russia’s Roscosmos space agency.

Hague reflected on the meaning of the season, saying, “Christmas is about spending time with friends, family, and loved ones. While we’re orbiting away from them this year, we know we’re not alone. A huge team on the ground in mission controls around the world is working to support us.”

He expressed gratitude to those teams, adding, “Their sacrifices keep this mission going, even over the holidays.”

A Holiday Feast in Space

The ground teams prepared a special holiday meal for the astronauts, which Pettit described as a feast fit for the season. “Christmas is synonymous with food and feasting,” he said. “And boy, do we have a feast packaged up here!”

Along with the meal, the crew decorated the station with a small artificial Christmas tree and ornaments featuring photos of their families.

A Festive Spirit

Hague, Pettit, and Wilmore donned Santa hats for the video, with Wilmore adding a personal touch by stretching his over a cowboy hat, a nod to his Tennessee roots. As an ordained minister and devout Christian, Wilmore also shared the spiritual significance of the holiday.

“Christmas is Christ. Hallelujah, a savior is born,” he proclaimed.

The astronauts closed their message with a heartfelt “Merry Christmas!”

A Cosmic Holiday Connection

For those on Earth, the holiday season offers its own celestial treats. Skywatchers can enjoy Venus and other planets lighting up the night sky, while history enthusiasts might explore the mystery of the Star of Bethlehem as astronomers continue to debate its origins.

From their unique vantage point in space, the ISS crew’s celebration serves as a reminder of the universal joy and togetherness that the holiday season inspires, whether on Earth or orbiting far above it.
