Moving day in space has a “you-haul” feel to it.
But is there a business in removing space junk from Earth orbit? Numbers of groups are coming up with concepts on grappling with worrisome debris. Nonetheless, estimates of how much troublesome litter – from huge chunks of space scrap to tiny paint chips and even radioactive particles – are daunting and tricky projections.

Leftover litter
When a satellite receives a come-to-blows punch by leftover litter or an explosion occurs in Earth orbit, particularly at higher altitudes, the detrimental results are additive. The debris resulting from these high-speed happenings lingers for years, decades, even centuries.
Netting of orbital debris has been studied, among a number of space junk-snatching ideas.

There’s no doubt about it. Earth orbit is a messy place.

The lunar leftovers of Russia’s failed Luna-25 robotic craft have likely been spotted by NASA’s Lunar Reconnaissance Orbiter (LRO).
Before and after imagery of the suspected Luna 25 impact site taken by LRO’s powerful LROC imaging system show landscape disturbance at the southwest rim of Pontécoulant G crater. The kicked-up terrain from the impact is roughly 250 miles (400 kilometers) short of Luna 25’s intended landing point.

“Since this new crater is close to the Luna 25 estimated impact point, the LRO team concludes it is likely to be from that mission, rather than a natural impactor,” according to a NASA statement.
The fresh crater is about 33 feet (10 meters) in diameter. The impact point was on the steep (greater than 20-degree grade) inner rim of Pontécoulant G crater.

Off-design orbit
During the descent to the surface, the Russian spacecraft Luna 25 experienced an anomaly that caused it to impact.
As noted by Russia’s Roscosmos, in accordance with the flight program of Luna-25, on August 19 it was planned to issue an impulse to form its pre-landing elliptical orbit.

However, “due to the deviation of the actual pulse parameters from the calculated ones, the automatic station switched to an off-design orbit and ceased to exist as a result of a collision with the lunar surface,” Roscosmos stated. Attempts on August 19-20 to regain contact with Luna-25 “did not produce any results.”
A specially formed interdepartmental commission has been established to identify the reasons for the loss of Luna-25.
Launched on June 18, 2009, NASA’s LRO is managed by the space agency’s Goddard Space Flight Center in Greenbelt, Maryland for the Science Mission Directorate at the agency’s Headquarters in Washington, D.C. LRO continues to collect a treasure trove of data, operated under the guidance of Arizona State University in Tempe, Arizona.

Hellish Venus is hot, not only temperature-wise but the planet is a hot topic for exploration. That cloud-veiled world might be a haven for high-altitude life.
Such a prospect is fostering the first-ever private interplanetary mission to Venus to search for signs of life in the clouds by detecting organic chemistry. The mission is planned for launch in January 2025 aboard Rocket Lab’s Electron rocket, an entrepreneurial launch vehicle provider.

Curiosity is wrapping up its mini-campaign of science collection at the upper Gediz Vallis Ridge reports Emma Harris, a graduate student at the Natural History Museum in London.
“Before we leave however, we want to collect as much data as we can! Next, Curiosity will be driving back to the nominal Mount Sharp Ascent Route (MSAR). We diverted from the MSAR back in June in order to navigate some tricky terrain, and then again briefly here at the uGVR [Gediz Vallis Ridge].”

Jam-packed plan
According to a recent plan, there’s a jam-packed two sols [Sols 3930-3931] in wrapping up at the ridge, Harris explains.
On tap is documenting five float rocks in the rover’s workspace that the robot “bumped” to in driving roughly 23 feet (7 meters) previously.

Over the next 2 sols, the rocks “Styx,” “Knossos,” and “Stravia” will be documented by Mastcam multispectral analysis.
ChemCam Laser Induced Breakdown Spectroscopy (LIBS) observations will be undertaken on Styx and on another float rock named “Elafonisos.”

“Elafonisos also receives complimentary Mastcam documentation,” Harris adds. “The terrain around here has been tricky to navigate, making it precarious to unstow Curiosity’s arm if we are perched on unstable rocks, but tosol was successful!”
Further afield
The arm was to be unstowed for Alpha Particle X-Ray Spectrometer (APXS) and Mars Hand Lens Imager (MAHLI) documentation of Knossos and the fifth and final float rock documented in this plan named “Meteora.”
“Aside from the immediate workspace, we also had time in the plan to look further afield,” Harris notes.

A Mastcam mosaic of the Mount Sharp Ascent Route and future drive direction will be taken, as well as two Mastcam mosaics of blocks and float rocks higher up within the Gediz Vallis Ridge, Harris reports.

Back to ascent route
The rover’s Chemistry and Camera (ChemCam) instrument is to take the lead for making two Long Distance Remote Micro-Imager (RMI) photo shoots of a block named “Argos” in the Gediz Vallis Ridge, and a second long distance RMI of the yardang unit higher up on Mount Sharp, Harris adds.

“Finally, the plan is rounded off with a Navcam dust devil survey and some morning atmospheric observations. Whilst I’m sure there are many folks that wish we could hang out at the uGVR [Gediz Vallis Ridge] for a while longer, Mount Sharp won’t climb itself, and it’s time to get back to the Mount Sharp Ascent Route,” Harris concludes. “Thanks Gediz Vallis Ridge!”
As always, dates/details of planned rover activities described in these reports are subject to change due to a variety of factors related to the Martian environment, communication relays and rover status.

Just in case you didn’t notice.
The U.S. State Department is embracing the concept of an “International Lunar Year” – coordinating programs around a one-to-two-year celebration of the study and exploration of the Moon later in the decade.
“As multiple nations and commercial entities plan a near-term return to the Moon on an unprecedented scale, now is the right time to consider planning an International Lunar Year,” a State Department website adds.

“A sustained program might combine elements of public outreach and scientific collaboration to fashion a vibrant interdisciplinary and multilateral effort, demonstrating how lunar exploration can be responsible, peaceful, and sustainable, as we begin to establish an enduring presence at the Moon.”
Indeed, such a celebration was put forth in a White House Office of Science and Technology Policy (OSTP) Cislunar Science & Technology Strategy Cislunar Science & Technology Strategy released in 2022.

Sample swaps
One avenue to explore is activating Moon sample swaps.
For instance, China has now opened access to the Chang’e-5 returned lunar samples to the international scientific community. That “get up and go” set of samples was rocketed to Earth back in mid-December 2020.
The haul from the Moon added up to roughly 61 ounces of lunar collectibles, including a core sample.

Chang’e-5 was the first lunar sample-return mission since the Soviet Union’s Luna 24 in 1976, making China the third country to return lunar samples after the United States and the former Soviet Union.
The Moon looms large in China’s space exploration plans over the next several years, and shooting to our home planet additional lunar samples is on their agenda.
Meanwhile, the Chinese National Space Administration (CNSA) has outlined opportunities and set the rules for future management of international cooperation in lunar samples and scientific data. Proposals will be reviewed every six months.

Diplomatic gestures
In retro-reflective mode, understanding the Moon has been revolutionized through the study of samples collected between 1969 and 1976 by the six Apollo human landing missions, along with three Luna missions carried out by the former Soviet Union.
“The legacy of the bilateral exchange of lunar samples as diplomatic gestures of goodwill transcends generations of lunar scientists,” explains a paper presented at a Lunar Exploration Analysis Group gathering back in 2021.
“As we enter this new golden era of lunar exploration, the U.S. and other nations must recognize the lasting legacy and benefit of the Apollo-Luna sample exchange program of the 1970s and explore new opportunities to share returned samples in the future,” the paper explains, led by planetary scientist, Jessica Barnes at the University of Arizona.

Current restrictions
So what next?
A recent gathering of the Extraterrestrial Materials Analysis Group (ExMAG) made note of access to China’s Chang’e lunar samples.
ExMAG is a community-based, interdisciplinary group that offers a forum for discussion and analysis of matters concerning the collection, curation, and analysis of extraterrestrial samples, including planning future sample return missions
A member gathering of ExMAG earlier this month noted that China has now opened access to the Chang’e-5 returned lunar samples to the international scientific community.
“ExMAG appreciates NASA’s efforts to pursue avenues of sample sharing with China and their Chang’E samples, though we recognize this is not possible under current restrictions,” an ExMAG finding explains.

Bilateral exchange
“ExMAG understands that sample loans made via this mechanism are considered bilateral agreements, which are prohibited for U.S. Government-funded researchers,” with the group recommending that U.S. Government-funded researchers who are interested in working on Chang’e-5 sample “form or join research teams with researchers in other nations who can request the samples for joint work.”

Bottom line: Given the White House/U.S. State Department moves on an International Lunar Year perhaps there’s a window opening to find avenues for U.S.-China Moon sample cooperation?
Perhaps it’s time to provide some new Moonwalking legs to build upon the legacy of bilateral exchange?

Earth’s Moon is a destination point for renewed human exploration. To sustain lunar crews, a wide number of technologies are needed to assure safe living and working conditions. Image credit: NASA
Before hurling to the Moon the mandatory hardware for astronauts to survive, thrive, and work in the ruthless lunar environment, how do you certify critical technology ahead of time?
Moon crews will be on their own, far from any repair shops or prompt 911 emergency response actions from Earth. What does it take to have, in a sense, “UL-approved” equipment – that is, Unified Luna machinery?

Recently, the Johns Hopkins University Applied Physics Laboratory (APL) brought together strategists and technologists to identify what’s needed to establish a Lunar Proving Grounds capability.
Lunar astronauts will need to count on fully-tested equipment to safely carry out a range of tasks, from deep drilling to utilizing the rich bounty of materials found on the Moon. Significant testing of technologies and techniques here on Earth prior to placement on the Moon is necessary.

Japan’s Smart Lander for Investigating Moon (SLIM) is set for liftoff, co-riding with the country’s X-Ray Imaging and Spectroscopy Mission (XRISM) – a new X-ray astronomical satellite carrying new generation of X-ray imaging spectroscopy technologies to resolve mysteries regarding the formation of the universe.
An H-IIA launch vehicle carrying the payloads will depart the Yoshinobu Launch Complex at the Japan Aerospace Exploration Agency’s (JAXA) Tanegashima Space Center.
The launch is slated for Sunday, August 27, 8:26 pm Eastern Time (9:26:22 a.m. Japan Standard Time (JST); 0:26:22 a.m. (UTC) on August 28, 2023).
Image credit: JAXA/ISAS
Landing objective
SLIM is to arrive in lunar orbit three to four months after launch, circuit the Moon for a month, then attempt a landing four to six months after launch.
The landing objective is to be within roughly 330 feet (100 meters) of the target point, the ejecta blanket of Shioli crater.

The feature is a small lunar impact crater located within the much larger Cyrillus crater on the near side of the Moon. It is a young crater with a prominent ray system.
The SLIM project aims to demonstrate pinpoint landing and obstacle detection techniques for touching down on the Moon.
Image processing
SLIM researchers are eager to convert conventional exploration of “descending where it is easy to land’” to “descending where you want to land.”
Image credit: JAXA/SLIM Project
The SLIM project is led by members of the JAXA Institute of Space and Astronautical Science (ISAS), and researchers from universities and other institutions across the country are working together to advance examination and development.
After reaching the sky above the landing site, the SLIM is to descend almost vertically while detecting the altitude with a landing radar. During this vertical descent phase, obstacle detection is performed at less than 985 feet (300 meters) above the lunar terrain.
SLIM is designed to process images captured by pointing a camera toward the lunar surface, recognizes craters, and compares them with the map of the lunar surface pre-loaded in memory to accurately measure its own position. SLIM engineers have developed a dedicated image processing algorithm with high computational efficiency to achieve both accuracy and processing time.

Sloping area
For showcasing landing technologies, the SLIM team has selected a target site neighboring the Shioli crater near the “Sea of Nectar.” The area has a relatively constant slope of 15 degrees or less, according to a SLIM press kit. “Therefore, the method of landing safely on such a slope becomes important.”
Landing on such sloping area will be increasingly required in the future.

In the case of SLIM, the main landing gear first touches the ground and then rotates forward to stabilize. This technique has shown excellent reliable landing results through simulation, the press kits states.

Transformer
SLIM is to deploy a palm-sized Lunar Excursion Vehicle 2 (LEV-2) jointly developed with toy manufacturer, Takara Tomy, along with the Sony Group Corporation and Doshisha University.
The ball-shaped vehicle — SORA-Q — is equipped with two cameras and can transform its shape to traverse the lunar surface.
The wheels that move freely left and right can run in two types of running modes, “butterfly running” and “crawling running” because the rotating shaft is eccentric, according to the Takara Tomy company.
The popular toy manufacturer is scheduled to release SORA-Q for public purchase in early September 2023. Manufacturer’s suggested retail price: 27,500 yen (tax included).
