Glass beads boost hopes for using the moon’s water

Beads of glass could become a key source of water for future crewed settlements on the moon, researchers say.

That claim is based on an assessment of the water contained within a sampling of glassy beads that were created over the course of millennia by cosmic impacts on the moon, and ended up being brought back to Earth in 2020 by China’s Chang’e-5 sample return mission.

A spectroscopic analysis determined that the beads contained more water than the researchers expected based on past studies. They surmised that interactions between hydrogen ions in the solar wind and oxygen-bearing materials in lunar soil created H2O molecules that could be trapped within the glass — and then diffused under the right conditions.

Based on an extrapolation of such findings, the research team — headed by scientists from the Chinese Academy of Sciences — estimates that glass beads in lunar soil may contain up to 270 trillion kilograms (595 trillion pounds, or 71 trillion gallons) of water.

“We propose that impact glass beads in lunar soils are a prime water reservoir candidate able to drive the lunar surface water cycle,” the researchers report in Nature Geoscience.

Chinese probe delivers moon samples to Earth

A Chinese probe has delivered the first samples to be collected from the moon in more than 40 years, and its mission isn’t done yet.

The Chang’e-5 sample return capsule floated down to the snowy plains of Inner Mongolia, capping an odyssey that began less than a month ago with the launch of a nine-ton spacecraft from south China’s Wenchang Space Launch Center.

Robotic Chinese spacecraft dock in lunar orbit

Two robotic Chinese spacecraft have docked in lunar orbit for the first time ever, in preparation for sending samples from the Moon to Earth.

The lunar ascent module for China’s Chang’e-5 mission was captured by the metal claws of the mission’s orbiter at 5:42 a.m. Beijing time Dec. 6 (1:42 p.m. PT Dec. 5), the China National Space Administration reported.

Over the half-hour that followed, a canister containing lunar material was safely transferred to the orbiter’s attached Earth-return capsule. In the days ahead, the ascent module will be jettisoned, and the orbiter will fire its thrusters to carry the return capsule back toward Earth.

If all proceeds according to plan, the orbiter will drop off the return capsule for its descent to Inner Mongolia sometime around Dec. 16, with the exact timing dependent on the mission team’s analysis of the required trajectory. That would mark the first return of fresh material from the Moon since the Soviet Luna 24 spacecraft accomplished the feat back in 1976.

Chinese probe lifts off from the moon with a full load

For the first time in more than 40 years, a robotic spacecraft has blasted off from the moon – and for the first time ever, it’s a Chinese spacecraft, carrying precious lunar samples back to Earth.

The ascent vehicle for the Chang’e-5 mission fired its engine and rose a region called Oceanus Procellarum at 7:10 a.m. PT (11:10 p.m. Beijing time) today, the China National Space Administration’s China Lunar Exploration Project reported.

Imagery sent back from the moon provided a view of the blastoff from ground zero. It was the first successful lunar launch since the Soviet Luna 24 probe took off during a sample return mission in 1976.

Here’s what China’s Chang’e-5 moon probe is seeing

China’s Chang’e-5 robotic moon lander is due to spend only two days collecting samples of lunar rock and soil before it sends its shipment on its way back to Earth, but it’s making the most of the time.

Just hours after landing on Dec. 1, the probe started using its robotic scoop and drill to dig up material at Mons Rümker, a lava dome in a region called Oceanus Procellarum, or the Ocean of Storms.

It’s also been sending back pictures and video, including this stunning view of the final minutes before touchdown. Watch how the camera tips straight down to focus on the target spot for the lander:

Chinese probe lands on the moon to bring back dirt

For the third time in seven years, a Chinese robotic spacecraft has landed on the Moon — but now things will get really interesting: If the Chang’e-5 mission succeeds, the probe will deliver fresh samples from the moon to Earth for the first time in 44 years.

Chang’e-5’s paired lander and ascent vehicle touched down in a lunar region known as Oceanus Procellarium, near Mons Rümker, today at 11:13 p.m. Beijing time (7:13 a.m. PT). The landing came eight days after the 9-ton spacecraft was launched from Wenchang Space Launch Center, and three days after the craft settled into lunar orbit.

In preparation for touchdown, the lander and ascent vehicle separated from its orbiter and descended to the surface. Chinese state-run television tracked the descent, climaxing with what appeared to be a close-up view of the lunar surface from a camera aboard the lander. China’s Xinhua news service confirmed the landing minutes later.

China launches mission to bring back moon samples

China launched a robotic probe today on a mission that could bring back the first samples of moon rocks and dirt in more than 40 years.

The Chang’e-5 spacecraft was sent into space from south China’s Wenchang Space Launch Center at 4:30 a.m. local time Nov. 24 (12:30 p.m. PT Nov. 23) atop a heavy-lift Long March 5 rocket.

Like China’s previous lunar probes, Chang’e-5 is named after a moon goddess in Chinese mythology. This probe consists of an orbiter, a lander, an ascent vehicle and a re-entry capsule.

The 9-ton craft went into an Earth-moon transfer trajectory that should get it to lunar orbit in five days. On Nov. 29 or so, the paired lander and ascent vehicle are expected to separate from the orbiter and touch down on a lava dome known as Mons Rümker.

The mound is thought to contain rocks that formed relatively recently in geological terms — 1.2 billion years ago. Samples from such a region could yield the youngest rocks ever brought back from the moon, and shed new light on recent phases of lunar geology.

Chang’e-5’s lander is designed to study its surroundings with cameras and scientific instruments, including a ground-penetrating radar and a spectrometer. The most important scientific payloads are a mechanical scoop and a drill that can go 7 feet beneath the surface.
