A new assessment of the recent Russian anti-satellite test has been released by the Outer Space Institute (OSI), based at the University of British Columbia in Vancouver, Canada.
The Russian military used a ground-based missile to strike their defunct Cosmos-1408 satellite on November 15, 2021.
The defunct Soviet-era satellite had a mass of about 1.7 metric tons (1,750 kilograms) and was orbiting at an altitude of about 298 miles (480 kilometers).
“Due to the high impact energies involved, debris from a kinetic anti-satellite (ASAT) test such as this end up on highly eccentric orbits that cross the orbits of 1000s of other satellites twice per revolution,” the OSI paper explains.

Non-trackable debris
While some of the debris from the Russian ASAT test will deorbit quickly, a significant fraction will remain in orbit for years or longer, the preliminary OSI discussion paper points out.
“Of particular concern is the non-trackable debris, which will be more abundant than the trackable debris by at least an order of magnitude. Since small debris cannot be detected, collision avoidance maneuvers cannot be used to protect against them. And at typical relative speeds of about 10 km/s (36,000 km/hr), even a tiny piece can disable a satellite or kill an astronaut,” the OSI paper adds.

NASA’s Curiosity Mars rover at Gale Crater is now performing Sol 3315 tasks.
Curiosity scored a perfect drive to some boulders that the science team have been interested in investigating, reports Lucy Thompson, a planetary geologist at University of New Brunswick; Fredericton, New Brunswick, Canada
“The large boulders are thought to represent the darker, resistant rocks exposed just above us that cap the underlying less resistant, lighter colored rocks we have been driving over,” Thompson adds.

Different textures
The caprocks and boulders both show two different textures; 1) layered and 2) more massive and irregular with cavities.
The team wants to examine these different textures in more detail and determine whether there are differences in composition between the two.

“We will also be able to compare the chemistry of these boulders with the pediment capping sandstones we analyzed when we first ascended the pediment. Does the more massive texture represent alteration of the layered caprock? This contact is an important one within Gale crater and represents an unconformity (a gap in time) between the underlying Mount Sharp group (laid down in lakes and rivers) and the overlying Siccar Point group (primarily wind-blown sedimentary rocks),” Thompson points out.

More massive rock
Recently, the robot placed the Alpha Particle X-Ray Spectrometer (APXS) and Mars Hand Lens Imager (MAHLI) instruments in contact with the “Yarrow Stone” target, which will allow Mars researchers to examine the chemistry and close-up texture of the more massive rock.
“We can compare the composition with the small, layered float, APXS target, ‘Camusnagaul,’” acquired in a recent plan, Thompson notes.
Curiosity’s Chemistry and Camera (ChemCam) will use passive spectroscopy to examine the same “Yarrow Stone” target, and the Laser Induced Breakdown Spectroscopy (LIBS) is slated to look at another spot on the same boulder (“Avochie”), also with the massive texture.

Source of boulders
Scientists want to examine the layered, “Borve” target on the same block with ChemCam LIBS. Mastcam will acquire complementary imaging of these targets and the surrounding area. MAHLI will also image two of the layered targets (“Whaligoe Steps” and “Arainn”), which we may try to place APXS on over the weekend. To investigate the probable source area for these boulders, we plan to take Mastcam and ChemCam [Remote Micro-Imager](RMI) imaging of the pediment.
Environmental monitoring activities will include a Navcam dust devil movie and line of site observation, a Mastcam tau.Standard Dynamic Albedo of Neutrons (DAN), Radiation Assessment Detector (RAD) and Rover Environmental Monitoring Station (REMS) activities round out the plan, Thompson concludes.

Road less traveled
Fred Calef, a planetary geologist at NASA’s Jet Propulsion Laboratory, also reports, the rover’s recent drive took the “road less traveled” to investigate a bunch of boulders shed down from a cliff face off to the side of our expected traverse to the south.
“Why? Beneath the Greenheugh Pediment, the flat-lying, high-standing escarpment to the west, the scientists could see a unique layer with a convoluted texture,” Calef says. The robot’s drive means the Mars machinery is headed to blocks from this layer that have rolled down close to the cliff base.

First, the rover will do some contact science with MAHLI on target “Camusnagaul,” which is likely a fragment from the top of the pediment.
Calef explains that ChemCam and Mastcam observations will be targeted on “Dutch Village” to create a higher resolution mosaic of the pediment.
Another Mastcam mosaic will be created on “Old Scatness” to document some partially exposed bedrock near the rover as well as one on the nearby boulder field, Calef concludes.

“We have been seeing many interesting features lately, including ones such as on the ChemCam RMI,” Schwenzer notes. “Let’s see what the new ones will reveal!”
“There is a drive in the plan, and after the drive Curiosity will look at an area with many boulders to give some context on future investigations,” Schwenzer concludes. Last but not least, the rover’s Mars Descent Imager (MARDI) will obtain a new picture too.

This November, the European Space Agency’s Mars Express spacecraft carried out a series of experimental communication tests with the Chinese (CNSA) Zhurong Mars rover.
Mars Express successfully caught data sent up ‘in the blind’ by the rover and relayed them to Earth where they were forwarded to the Zhurong rover team in China.

The experiments culminated in a successful test on November 20, ESA announced today.
Good quality data
“Mars Express successfully received the signals sent by the rover, and our colleagues in the Zhurong team confirmed that all the data arrived on Earth is very good quality.” says ESA’s Gerhard Billig.

The data relayed by Mars Express arrived on Earth at ESA’s ESOC space operations centre in Darmstadt, Germany, via deep-space communication antennas. From there, these data were forwarded to the Zhurong team at the Beijing Aerospace Flight Control Center, who confirmed the success of the test.
“We’re looking forward to carrying out more tests in the future,” Billig adds, “to continue to experiment and further improve this method of communicating between space missions.”
Decades of near-Earth space exploration and utilization have resulted in an increasingly congested environment. Indeed, pieces of space debris are a growing threat to space assets, human spaceflight and future access to outer space.
A just-issued report — Policy Options to Address Collision Risk from Space Debris – takes a hard look at the issue, offering recommendations to create improved response strategies.
The report comes from the International Risk Governance Center ( IRGC), a neutral interdisciplinary center based at the École Polytechnique Fédérale de Lausanne (EPFL) in Lausanne, Switzerland.

Limited shared resource
Called for is a “greater and more committed political involvement at the national and international levels,” deemed as instrumental to reducing collision risk from space debris and enabling sustainable space activities. Furthermore, there’s need to recognize that near-Earth space is a limited shared resource.
The report is divided into four chapters: Risk assessment and evaluation; Technology development and implementation; Regulatory requirements and compliance; and Multilevel governance of collision risk.

A pit crater, created by an empty lava tube, has been studied in Mars’ Arsia Mons region.
Using imagery captured in August 2020 by the High-Resolution Imaging Science Experiment, or HiRISE camera onboard NASA’s Mars Reconnaissance Orbiter, researchers appraise the pit at being about 150 feet (50 meters) across.

That measurement suggests it’s likely that the underground tube is also at least this big – much bigger than similar caves on Earth.
The use of lava tubes on Mars as emergency shelters and storage has been advanced in the past. Lava tubes are formed from fast moving lava which later cools and forms roomy caves that might serve various functions for future human expeditions to the Red Planet.

Detailed measurements
Meanwhile, data gleaned by a Radiation Assessment Detector (RAD) on NASA’s Curiosity Mars rover at Gale Crater has found a reduction in radiation when the rover was parked next to a butte on the Red Planet.
From B. Ehresmann, D. M. Hassler, et al. “Natural Radiation Shielding on Mars Measured With the MSL/RAD Instrument”
Designed by the Southwest Research Institute (SwRI) in Boulder, Colorado, RAD has been yielding detailed measurements of the radiation environment on the surface of Mars since Curiosity landed in August 2012.
“We will send astronauts to Mars, and when we do, protecting them from the environment is part of NASA’s responsibility,” said Don Hassler, RAD principal investigator and science program director at SwRI, as reported by the Boulder Daily Camera.
Hassler adds that fully understanding the radiation profile of Mars also raises the potential of fabricating astronaut shelters in lava tubes.
