Turn of the screw(s)
Two new multi-part tools were designed and fabricated to support further disassembly of the Touch and Go sample Acquisition Mechanism (TAGSAM) head.
These tools include newly custom-fabricated bits made from a specific grade of surgical, non-magnetic stainless steel. That’s the hardest metal approved for use in the pristine curation gloveboxes.

“Peregrine will soon return to Earth’s atmosphere and the vehicle is now about 234,000 miles away. We are working with NASA to continue updating and evaluating the controlled re-entry path of Peregrine,” notes a communiqué from the Pittsburgh, Pa.-situated Astrobotic – the private firm that designed and built the lunar lander.
“Working with NASA, we received inputs from the space community and the U.S. Government on the most safe and responsible course of action to end Peregrine’s mission,” the Astrobotic control team explained. “The recommendation we have received is to let the spacecraft burn up during re-entry in Earth’s atmosphere. Since this is a commercial mission, the final decision of Peregrine’s final flight path is in our hands.”

Cislunar preservation
While the Astrobotic crew has expertly extended the spacecraft’s life and operated payloads, the risk is that the damaged spacecraft could cause a problem in cislunar space, the communiqué explains.
“As such, we have made the difficult decision to maintain the current spacecraft’s trajectory to re-enter the Earth’s atmosphere. By responsibly ending Peregrine’s mission, we are doing our part to preserve the future of cislunar space for all,” the Astrobotic Update #17 adds.
The Astrobotic ground controllers did achieve a 200 millisecond burn, acquiring data that indicated Peregrine could have main engine propulsive capability.

However, the fuel to oxidizer ratio is well outside of the normal operating range of the main engines making long controlled burns impossible. The team projects that the spacecraft has enough remaining propellant to maintain sun pointing and perform small maneuvers, Astrobotic’s communiqué adds.
Misbehaving hardware
As for focusing on what took place that trashed the mission – apparently misbehaving valve hardware – Astrobotic said it designed and built hardware, avionics, software, and system architectures “that have all performed as expected in space.”
Back in July of 2018, Astrobotic selected Dynetics of Huntsville, Alabama as the propulsion provider for its Peregrine Lunar Lander. In December 2019, defense contractor Leidos acquired Dynetics.
While Astrobotic explains that the firm believes it possible for the spacecraft to operate for several more weeks and could potentially have raised the orbit to miss the Earth, “we must take into consideration the anomalous state of the propulsion system and utilize the vehicle’s onboard capability to end the mission responsibly and safely.”
The mission concludes on January 18, said Astrobotic CEO, John Thornton.
LRA (Laser Retroreflector Array) is a collection of eight retroreflectors that enable precise measurements of the distance between the orbiting or landing spacecraft and the lander.

In the future, rocketing in and precisely alighting on the moon’s craggy, rocky and crater-pocked face won’t be as hard.
NASA’s Lunar Retroreflector Array (LRA) program is engaged with U.S. and foreign lunar lander initiatives. An LRA is a dome-shaped device, topped by small glass corner cube prism retroreflectors. That contrivance is then mounted to a moon lander.
An LRA consists of eight tiny retroreflectors mounted on a small, high hemispherical platform.

Dotting the lunar landscape
The LRA can bounce laser light from other orbiting and incoming spacecraft, functioning as a permanent location marker on the moon for decades to come.
But dotting the lunar landscape with these devices has been a tough row to hoe.

Preparations are underway for the upcoming launch of China’s Tianzhou-7 cargo craft to that country’s space station.
As part of the process, the Tianzhou-6 separated from the orbiting station on Friday and switched to independent flight, according to the China Manned Space Agency (CMS).
Under ground control, Tianzhou-6 is headed for an ocean dumping within a designated zone in the southern Pacific Ocean.
The supply ship, launched in May of last year, was packed with supplies, spacesuits as well as maintenance components, application facilities and propellant to support the operations of the space station.

Making way
The Tianzhou-6 undocked from the aft port of China’s orbiting facility to make way for the arrival of the Tianzhou-7 cargo craft.
Tianzhou-6 will continue orbiting Earth until the Tianzhou-7 completes its docking with the space station.
As noted by China Central Television (CCTV), Tianzhou-6 marks the first mission of China’s improved cargo spacecraft. After the upgrade, the effective loading room was expanded by 20 percent compared with previous cargo-carrying ships, increased from 6.9 tons to 7.4 tons.
Meanwhile, the Tianzhou-7 is being readied for liftoff at Wenchang Spacecraft Launch Site in the southern island province of Hainan. The supply craft has been assembled with its booster, the Long March-7 Y8 launcher. The combination will be moved to the launch pad in the near future, reports CCTV.

NASA’s Office of Technology, Policy, and Strategy has released a long-awaited study from the space agency, one that sheds light on the future prospects of Space-Based Solar Power (SBSP).
Beaming power from space has been studied for decades. Over the last several years, other nations have also been studying the idea – including Europe and China.
“Our work identified several policy and technology challenges that would need to be addressed to advance SBSP. While these challenges are not unique to SBSP systems, the scale required to fully implement an SBSP system requires forethought,” the NASA review of SBSP states.
NASA technologies
“Our research indicates NASA is developing technologies with broad applicability to a wide suite of future mission needs and enable SBSP as well,” the report explains.

“However, we view SBSP as a use case for these technologies, not a driver for NASA’s development programs. We recommend that NASA stay abreast of outside SBSP developments and requirements as it matures the technologies needed for its missions. NASA could maintain its awareness in part by repeating this study at different scales of effort every three to five years,” adds the report.
The NASA SBSP report also concludes that NASA should continue to “monitor and maintain awareness” of ongoing developments in Space-Based Solar Power. “This option does not require any changes to NASA’s budget allocations.”

NASA is seemingly caught between a Mars rock and a hard place. Deemed the Holy Grail of Mars science for decades, the thought of robotically rounding up prized samples of the Red Planet and hurling them to Earth is in a holding pattern.
Last September, an independent review board (IRB) released its findings after taking a diligent and detailed look at the flagship Mars sample return (MSR) project. The IRB was established by NASA to judge the technical requirements, cost and calendar plans of the task.
It was a thorough sanity check on how things are going.
And things are not going well.
For more information, go to my new Scientific American story – “NASA’s Troubled Mars Sample Mission Has Scientists Seeing Red – NASA’s Mars Sample Return program is the agency’s highest priority in planetary science, but projected multibillion-dollar overruns have some calling the plan a “dumpster fire”” – at:

China’s next outbound Moon explorer is the Chang’e-6 spacecraft.
Components for that mission have arrived at the Wenchang Space Launch Site launch site, according to a statement today from the China National Space Administration (CNSA).
Scheduled for launch in the first half of this year, the Chang’e-6 mission is to showcase technologies in lunar retrograde orbit design and control, intelligent sampling on the Moon’s farside, and ascent from the lunar surface.
Far side science

The probe will also carry payloads from France, Italy, Pakistan and the European Space Agency, which include a negative ion detector and a radon gas detector, according to the CNSA.
Those components of the Chang’e-6 probe were transported by the An-124 and Y-20 transport aircraft, arriving at the Meilan International Airport in Haikou City on Monday and Tuesday, respectively, before they were transported by road to the Wenchang Spacecraft Launch Site some 80 kilometers away, as noted by China Central Television (CCTV).

As reported by China Global Television Network (CGTN), China will send the Chang’e-7 probe around 2026 to implement resource exploration of the lunar south pole and the Chang’e-8 around 2028 to conduct experiments on lunar resource utilization and to build the basic model of the International Lunar Research Station, citing China’s lunar exploration blueprint.
China has finished its three-step lunar exploration program of orbiting, landing and returning, with the Chang’e-5 lunar probe bringing back 1,731 grams of samples from the moon on December 17, 2020, adds CGTN.
Curiosity’s location as of Sol 4062, Distance driven to date: 19.35 miles/31.15 kilometers

NASA’s Curiosity Mars rover at Gale Crater is now performing Sol 4063 duties.
According to Abigail Knight, a graduate student at Washington University in St. Louis, Missouri, last weekend Curiosity performed a successful “bump backwards.”
The robot is now positioned “to execute contact science on a flat block of dark-toned bedrock in its workspace and continue investigating the composition and texture of the dark bands we’ve been observing from orbit,” Knight reports.

Science target
A recently scripted two-sol plan (Sols 4062-4063) was slated to start with a passive measurement by the Dynamic Albedo of Neutrons (DAN) experiment, followed by brushing of the contact science target “Chagoopa” and a brief Alpha Particle X-Ray Spectrometer (APXS) integration on the target.

Up next, rover scientists were to have a morning science block with Chemistry & Camera (ChemCam) observations of “Chagoopa,” target “Painted Lady” (an outcrop of fractured bedrock with an interesting polygonal texture), and a long-distance RMI of Milestone Peak (a deposit with large boulders).

Rock observations
Mastcam has planned observations of “Chagoopa,” “Saddlerock Lake,” an exposed truncation surface with a possible ventifact [a rock that has been abraded, pitted, etched, grooved, or polished by wind-driven sand], and “Rock Creek” (fractured rock), as well as an AEGIS activity. AEGIS stands for Autonomous Exploration for Gathering Increased Science – a software suite that permits the rover to autonomously detect and prioritize targets.
Mastcam will then image the Dust Removal Tool, and the Mars Hand Lens Imager (MAHLI) was to acquire imagery of “Chagoopa” from 25 cm, 5 cm, and 2 cm away.

After the morning science block, Curiosity was slated to drive about 52 feet (16 meters) to some polygonal fractured material, and the rover’s Mars Descent Imager (MARDI) was scheduled to perform a video activity to document the fractures.
Clasts and soils

“Following this, we have post-drive imaging to assist the rover planners, identify targets for the next plan, and systematically document clasts and soils along the traverse,” Knight notes.
MARDI was scheduled to acquire a single image at twilight to close out the first sol of this plan.
The second sol begins with another DAN passive and an untargeted science block in the morning.
“This science block includes ChemCam AEGIS of bedrock, a Navcam line-of-sight observation, and a Navcam dust devil movie,” Knight concludes. “The planned contact science observations of the dark-toned bedrock target in our workspace will inform a decision on potentially drilling the rocks in this region again or not.”

Enhanced experience
The film was produced privately from archival material (visual and audio) retrieved from the period of the Apollo program.
“The exploration experience is further enhanced by including brief clips of familiar music during the Apollo era,” says Scott. “This provides another dimension to the visual scenes.”
The upgraded 50th Anniversary film of Apollo 15 will be released on the “Apollo 15 learning Hub” at 10 am Eastern Standard Time, January 10.

Russia’s Roscosmos is outlining a new space station, named Russian Orbital Station (ROS).
According to a recent Roscosmos posting, they emphasize its main advantage: “virtually unlimited development.”
That virtually unlimited development is thanks to the node module. “It, as a universal design part, will allow you to dock and later replace any modules in almost any quantity,” the posting explains.
The node module will be a sphere with six docking nodes and fly with minimum service systems and easy to repair. Its service life is slated to be higher than that of other modules.

Prichal module
A prototype of such a “core” has already been tested on the International Space Station – the “Prichal” module, the posting adds.
The five-ton Prichal docking module was propelled to the ISS in November 2021 by a modified Russian Progress propulsion compartment. Prichal is a Russian word for pier and has five available docking ports to accommodate multiple Russian spacecraft and provide fuel transfer capability.
“If necessary, the old ‘core’ can be removed from orbit. It’s just that to do this, you first need to dock the new one in a different place.”
The expected service life of the ROS is 50 years.
“During this time, three generations of different modules may change,” the Roscosmos posting concludes.
