Is the moon shrinking? Here’s what scientists say
New research suggests that the moon’s South Pole, a hotspot for future exploration, might be more challenging than expected due to “moonquakes” and landslides.
The moon's allure as a target for space agencies like NASA and private companies like SpaceX is undeniable. But a recent study funded by NASA throws a cautionary flag on the lunar South Pole, a region rich in potential water ice and the target for several upcoming missions, reports CNN.
The study revealed that the moon’s core is cooling and shrinking, causing its surface to wrinkle and crack, similar to a raisin, it said.

These “faults” trigger moonquakes lasting for hours and landslides, potentially posing a threat to future human settlements and equipment.
The moon may seem geologically dead, but its interior is still hot, making it seismically active. The study links a powerful moonquake detected by Apollo astronauts to faults near the South Pole, highlighting the potential dangers.
While the findings won’t affect the upcoming Artemis III mission due to its short duration, they raise concerns for long-term lunar settlements. Future site selection may consider factors like proximity to tectonic features.

Yosio Nakamura, , a professor emeritus of geophysics at the University of Texas at Austin, who was among the researchers who first looked at the data collected by the Apollo seismic stations, disagreed with the study’s cause of shallow moonquakes, suggesting they originate deeper within the moon. He emphasized the need for more data.
Allen Husker, a research professor of geophysics at the California Institute of Technology, said “It is very unlikely that a large moonquake will happen while they are there. However, it is good to know that these seismic sources (causing the quakes) exist. They can be an opportunity to better study the moon as we do on the earth with earthquakes,” Husker said. “By the time there is an actual moon base, we should have a much better idea of the actual seismic hazard with upcoming missions.”
Jeffrey Andrews, an associate professor of planetary science at the University of Arizona, said, “Moonquakes are an incredible tool for doing science.” “They are like flashlights in the lunar interior that illuminate its structure for us to see. Studying moonquakes at the South Pole will tell us more about the moon’s interior structure as well as its present-day activity,” he added.

India launches spacecraft to study the sun after successful landing near the moon's south pole
India launched its first space mission to study the sun on Saturday, less than two weeks after a successful uncrewed landing near the south polar region of the moon.
The Aditya-L1 spacecraft took off on board a satellite launch vehicle from the Sriharikota space center in southern India on a quest to study the sun from a point about 1.5 million kilometers (930,000 miles) from earth.

The spacecraft is equipped with seven payloads to study the sun's corona, chromosphere, photosphere and solar wind, the Indian Space Research Organization said.
India became the first country to land a spacecraft near the moon's south pole on Aug. 23 — a historic voyage to uncharted territory that scientists believe could hold vital reserves of frozen water. After a failed attempt to land on the moon in 2019, India joined the United States, the Soviet Union and China as only the fourth country to achieve this milestone.
The sun study, combined with India's successful moon landing, would completely change the image of ISRO in the world community, said Manish Purohit, a former ISRO scientist.

The Aditya-L1 was headed for the L1 point of the Earth-Sun system, which affords an uninterrupted view of the sun, ISRO said. "This will provide a greater advantage of observing solar activities and their effect on space weather in real-time."
Once in place, the satellite would provide reliable forewarning of an onslaught of particles and radiation from heightened solar activity that has the potential to knock out power grids on Earth, said B.R. Guruprasad, a space scientist, in an article in The Times of India newspaper. The advanced warning can protect the satellites that are the backbone of global economic structure as well as the people living in space stations.

NASA Orion capsule safely blazes back from moon, aces test
NASA’s Orion capsule made a blisteringly fast return from the moon Sunday, parachuting into the Pacific off Mexico to conclude a test flight that should clear the way for astronauts on the next lunar flyby.
The incoming capsule hit the atmosphere at Mach 32, or 32 times the speed of sound, and endured reentry temperatures of 5,000 degrees Fahrenheit (2,760 degrees Celsius) before splashing down west of Baja California near Guadalupe Island. A Navy ship quickly moved in to recover the spacecraft and its silent occupants — three test dummies rigged with vibration sensors and radiation monitors.
NASA hailed the descent and splashdown as close to perfect, as congratulations poured in from Washington..
“I'm overwhelmed,” NASA Administrator Bill Nelson said from Mission Control in Houston. “This is an extraordinary day ... It's historic because we are now going back into space — deep space — with a new generation.”
Read more: NASA's Orion capsule reaches moon, last big step before lunar orbit
The space agency needed a successful splashdown to stay on track for the next Orion flight around the moon, targeted for 2024 with four astronauts who will be revealed early next year. That would be followed by a two-person lunar landing as early as 2025 and, ultimately, a sustainable moon base. The long-term plan would be to launch a Mars expedition by the late 2030s.
Astronauts last landed on the moon 50 years ago. After touching down on Dec. 11, 1972, Apollo 17′s Eugene Cernan and Harrison Schmitt spent three days exploring the valley of Taurus-Littrow, the longest stay of the Apollo era. They were the last of the 12 moonwalkers.
Orion was the first capsule to visit the moon since then, launching on NASA’s new mega moon rocket from Kennedy Space Center on Nov. 16. It was the first flight of NASA’s new Artemis moon program, named after Apollo’s mythological twin sister.
“From Tranquility Base to Taurus-Littrow to the tranquil waters of the Pacific, the latest chapter of NASA’s journey to the moon comes to a close. Orion back on Earth,” announced Mission Control commentator Rob Navias.
While no one was on the $4 billion test flight, NASA managers were thrilled to pull off the dress rehearsal, especially after so many years of flight delays and busted budgets. Fuel leaks and hurricanes conspired for additional postponements in late summer and fall.
In an Apollo throwback, NASA held a splashdown party at Houston’s Johnson Space Center on Sunday, with employees and their families gathering to watch the broadcast of Orion’s homecoming. Next door, the visitor center threw a bash for the public.
Getting Orion back intact after the 25-day flight was NASA’s top objective. With a return speed of 25,000 mph (40,000 kph) — considerably faster than coming in from low-Earth orbit — the capsule used a new, advanced heat shield never tested before in spaceflight. To reduce the gravity or G loads, it dipped into the atmosphere and briefly skipped out, also helping to pinpoint the splashdown area.

All that unfolded in spectacular fashion, officials noted, allowing for Orion’s safe return.
“I don't think any one of us could have imagined a mission this successful," said mission manager Mike Sarafin.
Further inspections will be conducted once Orion is back at Kennedy by month’s end. If the capsule checks find nothing amiss, NASA will announce the first lunar crew amid considerable hoopla in early 2023, picking from among the 42 active U.S. astronauts stationed at Houston’s Johnson Space Center.
“People are anxious, we know that,” Vanessa Wyche, Johnson's director, told reporters. Added Nelson: “The American people, just like (with) the original seven astronauts in the Mercury days, are going to want to know about these astronauts.”
The capsule splashed down more than 300 miles (482 kilometers) south of the original target zone. Forecasts calling for choppy seas and high wind off the Southern California coast prompted NASA to switch the location.
Orion logged 1.4 million miles (2.25 million kilometers) as it zoomed to the moon and then entered a wide, swooping orbit for nearly a week before heading home.
It came within 80 miles (130 kilometers) of the moon twice. At its farthest, the capsule was more than 268,000 miles (430,000 kilometers) from Earth.
Orion beamed back stunning photos of not only the gray, pitted moon, but also the home planet. As a parting shot, the capsule revealed a crescent Earth — Earthrise — that left the mission team speechless.
Nottingham Trent University astronomer Daniel Brown said the flight's many accomplishments illustrate NASA's capability to put astronauts on the next Artemis moonshot.
“This was the nail-biting end of an amazing and important journey for NASA’s Orion spacecraft," Brown said in a statement from England.
The moon has never been hotter. Just hours earlier Sunday, a spacecraft rocketed toward the moon from Cape Canaveral. The lunar lander belongs to ispace, a Tokyo company intent on developing an economy up there. Two U.S. companies, meanwhile, have lunar landers launching early next year.

Crescent moon sighted; Saudi Arabia to celebrate Eid-ul-Azha on July 9
Saudi Arabia will celebrate Eid-ul-Azha, the feast of the sacrifice, on July 9, as the crescent moon of Zilhajj was sighted Wednesday.
The sighting of the crescent moon of Zilhajj, the month in which the hajj pilgrimage takes place, was confirmed at the Tamir Observatory, near Riyadh, in the evening, according to the Saudi Supreme Court.
So, Thursday will be the first day of Zilhajj, the twelfth and final month of the Islamic calendar.
The first day of Eid-ul-Azha, the second-largest religious festival for Muslims, will be on July 9 in most Arab and Muslim countries while many Southeast and South Asian countries will start the celebrations on July 10.
Usually, the crescent of Zilhajj is first sighted in Saudi Arabia and then a day later in Bangladesh, Pakistan, and some other countries.
Today, Pakistan, Malaysia, Indonesia, Japan, Hong Kong and Brunei announced July 10 as the first day of Eid-ul-Azha.
The religious festival marks the end of hajj and commemorates Prophet Ibrahim's willingness to sacrifice his son Ismail on Allah's will.
Prophet Ibrahim was eventually given a lamb to sacrifice. So, Muslims perpetuate the tradition by slaughtering a lamb or a cow and sharing the meat with people in need.
This year's hajj will start on July 6 and Eid-ul-Azha will be three days later in Saudi Arabia.
Muslims around the world celebrate Eid-ul-Azha almost the same way with the morning being marked with Eid prayers and the slaughtering of sacrificial animals. The celebration last for three days.

Toyota heading to moon with cruiser, robotic arms, dreams
Toyota is working with Japan’s space agency on a vehicle to explore the lunar surface, with ambitions to help people live on the moon by 2040 and then go live on Mars, company officials said Friday.
The vehicle being developed with the Japan Aerospace Exploration Agency is called Lunar Cruiser, whose name pays homage to the Toyota Land Cruiser sport utility vehicle. Its launch is set for the late 2020’s.
The vehicle is based on the idea that people eat, work, sleep and communicate with others safely in cars, and the same can be done in outer space, said Takao Sato, who heads the Lunar Cruiser project at Toyota Motor Corp.
“We see space as an area for our once-in-a-century transformation. By going to space, we may be able to develop telecommunications and other technology that will prove valuable to human life,” Sato told The Associated Press.

Gitai Japan Inc., a venture contracted with Toyota, has developed a robotic arm for the Lunar Cruiser, designed to perform tasks such as inspection and maintenance. Its “grapple fixture” allows the arm’s end to be changed so it can work like different tools, scooping, lifting and sweeping.
Gitai Chief Executive Sho Nakanose said he felt the challenge of blasting off into space has basically been met but working in space entails big costs and hazards for astronauts. That’s where robots would come in handy, he said.
Since its founding in the 1930s, Toyota has fretted about losing a core business because of changing times. It has ventured into housing, boats, jets and robots. Its net-connected sustainable living quarters near Mount Fuji, called Woven City, where construction is starting this year.
Japanese fascination with the moon has been growing.
A private Japanese venture called ispace Inc. is working on lunar rovers, landing and orbiting, and is scheduled for a moon landing later this year. Businessman Yusaku Maezawa, who recently took videos of himself floating around in the International Space Station, has booked an orbit around the moon aboard Tesla CEO Elon Musk’s Starship.
Toyota engineer Shinichiro Noda said he is excited about the lunar project, an extension of the automaker’s longtime mission to serve customers and the moon may provide valuable resources for life on Earth.
