On December 1, 2020, the 57 year old 305-meter Arecibo Telescope in Puerto Rico collapsed after a series of failures of the supporting cables.

While no longer collecting scientific data, components of the telescope may be preserved for historical and educational purposes.

The AO facility of the National Science Foundation operated under cooperative agreement by the University of Central Florida.

Critical salvage pieces

“In order to have a minimal impact on the environment, the clean-up of the site happened very quickly,” says Luisa Fernanda Zambrano-Marin, an AO analyst and co-Chair of the salvage survey committee. “This meant we had to work fast to identify the most critical pieces to salvage.”

Zambrano-Marin adds that, through nineteen weeks of weekly meetings, site visits, and a close study of hundreds of high-resolution survey photographs taken by AO-operated drones, the committee created a database of high-priority items and cataloged the actual pieces collected during the emergency cleanup. “We marked the salvageable items with pink neon construction tape to indicate that they should not be carried away by the clean-up crew.”

“This is history,” notes Zambrano-Marin. “This is part of the bulk of technological wonders that allowed us to make great discoveries in astronomy, planetary science, and space and atmospheric science.”

Historical items

Among the items, radar klystron hardware, a recovered feed array, pieces of the Gregorian dome and the platform, even a landing step from the cable cart that led onto the platform.

Some of the historical items have already been put on display at Arecibo’s Ángel Ramos Science and Visitor’s Center, which reopened to the public on March 10, 2022.

“It’s so important to be able to show visitors to the observatory or a museum the ‘real thing’ – something that actually captured the radio signals from a pulsar or transmitted a radar signal all the way to Titan,” says Bruce Campbell of the Smithsonian Institution and also served on the salvage survey group. “Those artifacts also provide a link to the human stories of the engineers and scientists that built and used them.”

Campbell adds that he hopes that in the long term “these objects will be preserved and displayed in ways that tell those stories and inspire students to go into fields like engineering, radio astronomy, or planetary science.”

Ultimate fate

Tracy Becker, an AO collaborator and Southwest Research Institute research scientist, explains that the ultimate fate of the recovered pieces of the legacy telescope is yet to be determined.

The final recommendations from the salvage survey committee, Becker explains, “include the need for action to protect the artifacts from further damage or corrosion, distribution of historic and technical information about the instruments and structural elements to museums and universities, and the formation of a follow-on group to consider the long-term preservation and educational potential of the recovered material.”

For you future moonwalkers, you may be wearing a knapsack that provides precise navigation capabilities on the Moon.

NASA’s Kinematic Navigation and Cartography Knapsack (KNaCK) Instrument project is designed to overcome the lack of global positioning and navigation systems on a person’s lunar outings.

KNaCK is to support missions that are part of NASA’s Artemis program, particularly at the Moon’s South Pole. In that region the low solar incidence means that the sun never appears more than three degrees above the horizon.

In this multi-temporal illumination map of the lunar south pole, Shackleton crater (19 km diameter) is in the center, the south pole is located approximately at 9 o’clock on its rim. The map was created from images from the camera aboard the Lunar Reconnaissance Orbiter.

LiDAR-based

As a LiDAR-based (Light Detection and Ranging) mobile terrain-mapping and navigation system, the concept is using Aeva Technologies, Inc.’s 4D LiDAR technology. Based in Mountain View, California, Aeva’s technology, including the new Aeries™ II sensor, is expected to enable the KNaCK Instrument to create highly accurate maps of the lunar surface and provide precise navigation capabilities to conquer the lack of GPS guidance on the Moon.

“The KNaCK sensor is a surveying tool for both navigation and science mapping, able to create ultra-high-resolution 3D maps at centimeter-level precision,” said Michael Zanetti, KNaCK Project Manager and Principal Investigator at NASA’s Marshall Space Flight Center, in a NASA release.

GPS-denied environment

A next-generation space-hardened unit will be about the size of a soda can and could enable lunar surface operations like never before. “It also will help ensure the safety of astronauts and rover vehicles in a GPS-denied environment such as the Moon,” Zanetti said, “identifying actual distances to far-off landmarks and showing explorers in real time how far they’ve come and how far is left to go to reach their destination.”

The lunar south pole region also has areas that are permanently shadowed or have long persistent shadows that prohibit photogrammetry-based navigation. Aeva’s Frequency Modulated Continuous Wave technology is immune to optical interference from the sun and can operate in the dark, allowing astronauts and rovers to use the KNaCK Instrument to explore and map the lunar surface anytime, day or night.

According to a Aeva statement, beyond the benefits of mapping and navigation, Aeva’s high-resolution sensor data can also be used to create high-definition terrain maps, useful for landing site visualizations. The KNaCK project is also exploring additional applications that leverage Aeva’s instant velocity-sensing capabilities to detect airborne particulates, such as the way rocket plume exhaust interacts with lunar and planetary surfaces and for measuring small scale atmospheric phenomena like dust devils.

Field testing

NASA’s Zanetti said he envisions mounting KNaCK on a rover or on the side of an astronaut’s helmet – which should leave plenty of room in future lunar mountaineers’ all-purpose backpacks.

The KNaCK team will work to miniaturize the hardware – the backpack prototype weighs about 40 pounds – and harden the sensitive electronics against the punishing effects of microgravity and solar radiation.

The hardware is set to be evaluated in another major field test in late April at NASA’s Solar System Exploration Research Virtual Institute (SSERVI) in Kilbourne Hole, New Mexico.

A NASA technology demonstration mission integrates several new technologies aboard a small satellite to validate solar sail propulsion.

Solar Cruiser is sponsored by the NASA Heliophysics Division’s Solar Terrestrial Probes Program. Utah State University’s Space Dynamics Laboratory (SDL) in North Logan Utah announced today that it has been awarded a contract to build two space-based radios for the mission.

The contract was awarded by Solar Cruiser prime contractor Ball Aerospace, which is providing the small satellite.

Space weather watch

NASA’s Marshall Space Flight Center is developing the Solar Cruiser mission, set to fly in 2025, to mature solar sail propulsion technology for future missions.

Solar Cruiser will deploy the ultra-thin reflective sail – the largest sail ever flown — with an area of 1,650 square meters (17,800 square feet). That’s large enough to cover more than six tennis courts.

Solar Cruiser will also demonstrate technologies that will enable subsequent missions to improve space-weather monitoring, prediction, and science.

Information provided by Solar Cruiser will allow scientists, engineers, and mission planners to discern better how solar sail propulsion can be used by spacecraft to collect observations from novel vantage points that are difficult to reach and sustain.

The SDL-built Iris radios onboard Solar Cruiser will fly approximately one million miles sunward of the Earth at Lagrange Point L1, the position in space where Earth’s and the Sun’s gravity are balanced along the Sun-Earth-line, and relay mission data to NASA’s Deep Space Network and other ground networks.

Smallsat growth

In an SDL statement, Asal Naseri, SDL’s satellite technologies branch head for civil and commercial space, said: “As more small satellites operate in deep space, there is a correlating need for radios that can function in the unique conditions of deep space.”

Naseri also added that the space industry has experienced a rapid ascent of spacecraft with masses of less than 500 kilograms—classified as small satellites—and related technologies used for technology demonstration, science, commercial and other applications. “Last year, more than 1,700 small satellites were launched, compared to 1,163  in 2020, and 757 in 2019.”

The End of Astronauts – Why Robots Are the Future of Exploration by Donald Goldsmith and Martin Rees; The Belknap Press of Harvard University Press (April 2022); 192 pages; Hardcover: $25.95

My guess is that the reader will either hate or love this book! However, the authors provide a provoking argument for space exploration sans astronauts.

Just a few pages into the book, in an introduction, there’s this forewarning: “Readers who disagree with the conclusions in this book will, we hope, enjoy considering which arguments carry more weight than others.”

That said, this volume is a tour de force of well-written, compelling rationales. The authors believe that beyond low-Earth orbit, space exploration should proceed without humans.

The book is divided into 9 chapters: Why Explore?, Organizing Space,  Near-Earth Orbit, The Moon,  Mars, Asteroids, Space Colonization, The Global Costs of Space Exploration, and Space Law. So pick your favorite destination/topic and brace yourself.

An epilogue covers perspectives on space exploration in 2040—and far beyond, followed by an appendix of key events in space exploration, as well as notes and a further reading section.

The United Kingdom’s Astronomer Royal, Martin Rees, was previously Professor of Astronomy and Director of the Institute of Astronomy at the University of Cambridge.

Well-regarded science writer, Donald Goldsmith, has written more than a dozen books, including Exoplanets, The Runaway Universe, The Hunt for Life on Mars, Supernova, and, with Neil deGrasse Tyson, Origins.

At its core, the book notes that human journeys into space fill us with wonder. But the thrill of space travel for astronauts comes at enormous expense and is fraught with peril. More to the point, as surrogate automatons become increasingly competent, this question becomes more potent: does our desire to send astronauts to the Moon and Mars justify the cost and danger?

Goldsmith and Rees weigh the benefits and risks of human exploration across the solar system. In space, humans require air, food, and water, along with protection from potentially deadly radiation and high-energy particles.

And all that comes at a cost more than ten times that of robotic exploration.

Automated explorers have shown the ability to investigate planetary surfaces efficiently and effectively, operating autonomously or under direction from Earth. They note that the performance of robots and AI is progressively improving – while our bodies do not.

The reader will find much to ponder in this book, chock-full of up-to-date observations and eye-opener viewpoints. Sure, some of you will have a “bone to pick” about the need for human space travel…others will see the “nuts and bolts” of how space exploration will be done in the future.

Russia’s Roscosmos continues to implement a national lunar program, planning to implement three lunar missions in the coming years:

  • Luna-Glob (Luna-25)
  • Luna-Resource-1 (Luna-26) with an orbital spacecraft
  • Luna-Resurs-1” (“Luna-27) with a lander

“To date, the Luna-25 spacecraft, which is the first of the renewable domestic lunar program, is fully equipped with standard models of instruments and systems,” according to Roscosmos.

Dismantling of ESA’s Pilot-D

Given the recent decision by the European Space Agency (ESA) to no longer participate in Russia’s Luna program, “the dismantling of the Pilot-D device is planned to be carried out at the stage of assembly of the flight model,” Roscosmos has stated.

ESA’s Pilot-D camera was to image the lunar terrain, hardware built specifically for Luna-25’s Moon landing.

“The refusal of European partners to participate in cooperation on the Luna-25 project will not affect its implementation in any way,” Roscosmos explains.

Launch date?

Meanwhile, the launch date of Luna-25 is to be determined after testing.

Dmitry Rogozin, general director of Roscosmos, explains that the launch of the Luna-25 from the Vostochny cosmodrome can take place both earlier and later on August 22 reports RIA Novosti, a Russian state-owned domestic news agency.

“So far, Lavochkin’s NPO has named this date. It could be earlier, maybe in September,” Rogozin told reporters at the Tsiolkovsky Museum of the History of Cosmonautics in Kaluga.

Rogozin clarified that only one very important test remained in the preparation schedule: a repeat test of a Doppler receiver. After all the necessary confirmations of the readiness of the device for launch are received, the specialists will determine the launch date.

No pressure

The general director of the state corporation also urged not to put pressure on the engineers preparing Luna-25 for launch, and to not demand a specific launch date from them.

Earlier, Alexander Mitkin, deputy general designer for electrical systems at NPO Lavochkin – the designer and builder of Luna-25 — said that the launch of the first domestic mission to the Moon in 46 years from the Vostochny cosmodrome is scheduled for August 22.

Later, Rogozin said that the launch was simply scheduled for the third quarter of 2022.

NASA’s Curiosity Mars rover at Gale Crater is now performing Sol 3451 duties.

Reports Susanne Schwenzer, a planetary geologist at The Open University, Milton Keynes, U.K., the rover has again found itself dealing with a rock right under the Mars machinery.

“But this time, we were excited about it as the rover was in a stable position parked on a big piece of bedrock, presenting itself flat as a pancake, ready to be brushed and analyzed.”

Warm season

But there was a problem that required discussion, Schwenzer adds.

A recent plan was originally a ‘touch-and-go’ sol, where the robot puts the Alpha Particle X-Ray Spectrometer (APXS) down for a short integration before driving away.

“Those ‘touch-and-go’ measurements return brilliant analysis throughout most of the Martian seasons,” Schwenzer explains, “but right now we are in a warm season, and that means it’s too warm for really good data at the time those ‘touch-and-go’ measurements are happening.”

Different rock types

Therefore the science team discussed carefully how important the target is, and if it warrants the rover to stay in place to get the APXS measurement at a colder time of the day, and therefore get the best possible data quality.

“Once again, rover progress had to be weighed against the importance of the data. We decided the diversity of the region and the quality of the targets, together with the hypothesis on the different rock types and their formation we can test here warrants us to stay,” Schwenzer notes.

Data feast

As a result there is a plethora of science activities in the plan, and the team is looking forward to have another data feast over the weekend -and of course to seeing the data.

Here are the details:

APXS and the Mars Hand Lens Imager (MAHLI) have two and three activities, respectively.

“The pancake-shaped rock the rover is parked on will be brushed and investigated with APXS and MAHLI on a target called ‘Shandon.’ APXS and MAHLI are also investigating the edge of the bedrock on a target called ‘Nesting,’ which is at the edge of the big, flat rock and allows side-on view,” Schwenzer reports.

Curiously bright

Finally, MAHLI is looking at ‘Rumblings,’ which is a curiously bright and textured target that the team thinks might be alteration features and would like to know more about. MAHLI will likely also allow for APXS in a future plan, despite the targets being a bit spikey.

“The MAHLI images will show if we can get APXS to touch in a safe way, but of course, MAHLI images are always welcome science data, too, especially on textured targets like this one,” Schwenzer points out.

Chemistry and Camera (ChemCam) is investigating two targets, ‘Tonga,’ which is on the bedrock and ‘Kirby Lonsdale,’ a vein target.

Multispectral investigation

“Mastcam is taking documentation images of the two ChemCam targets and doing a multispectral investigation on the brushed area,” Schwenzer adds. “More Mastcam images are planned in form of a 16×4 mosaic on the target ‘Onich Dry Gorge,’ which was imaged from a distance and we are now getting much higher resolution images from a closer distance.”

ChemCam is adding to the images through a long distance Remote Micro-Imager (RMI) and an RMI of rocks broken up by the rover wheels.

“Lots of data and images, and more to come over the weekend at this interesting location,” Schwenzer concludes.

China’s Tianzhou-3 cargo ship detached on Wednesday from the rear docking port of the country’s space station core module Tianhe. It moved to the module’s front port and completed a computer-orchestrated rendezvous and docking, according to the China Manned Space Agency (CMSA).

CMSA also reported that the combination of Tianhe and Tianzhou-3 is in good condition.

Now in this configuration, the next step is the upcoming launch of the Tianzhou-4 cargo craft, the Shenzhou-14 manned spaceship and the lab module Wentian.

A total of six missions are planned for this year, including the launch of the Tianzhou-4 cargo spacecraft in May, the Shenzhou-14 manned spacecraft in June, the lab module Wentian in July, and the lab module Mengtian in October.

The three modules will form a T shape to complete the in-orbit construction of China’s space station by the end of 2022.

NASA’s Curiosity Mars rover at Gale Crater is now performing Sol 3449 duties.

“Due to some complex terrain, the rover’s last drive came up about ten meters short of the target destination,” reports Mariah Baker, a planetary geologist at the Center for Earth & Planetary Studies within the Smithsonian National Air & Space Museum.

“The rover’s unexpected parking orientation unfortunately will not allow our usual uplink direct from Earth. We can instead send the weekend’s commands through one of the orbiters at Mars, but a little later than planned,” Baker adds.

Sand and rocks

As a result, a recently scripted plan for Sols 3446-3448 had to be adjusted accordingly. Weekend plans typically include three sols of science, Baker notes, but all the activities for this last weekend had to occur with the second and third sols only.

Luckily, the primary targeted science block on the second sol was increased from one hour to two hours, providing ample time to acquire data at this location before driving away, Baker pointed out.

This block was filled with remote science activities to characterize sand and rocks in the rover’s workspace.

Sedimentary textures

A Chemistry and Camera (ChemCam) Laser Induced Breakdown Spectroscopy (LIBS) activity was planned on bedrock target “Easter Skeld,” and two ChemCam Remote Micro-Imager (RMI) mosaics will be used to target the distant Gediz Vallis Ridge.

Three Mastcam stereo mosaics were planned to document the surface around the LIBS target, Baker explains, to characterize some nearby sand ripples, and to extend coverage over interesting sedimentary textures in the target “Lugar Rocking Stone.”

Curiosity’s Mastcam will also be used to re-image wheel tracks that the rover made during its initial traverse of this area over a month ago to search for any wind-driven changes in the tracks.

Untargeted science block

The untargeted science block on the third sol also contains a single ChemCam AEGIS observation. AEGIS stands for Autonomous Exploration for Gathering Increased Science) – a software suite that permits the rover to autonomously detect and prioritize targets.

The team decided to forego weekend Alpha Particle X-Ray Spectrometer (APXS) activities due to the changes in the plan, but three sets of Mars Hand Lens Imager (MAHLI) photos were still scheduled on soil target “Bains Beach,” a small rock named “Spiggie Beach,” and one of the rover’s wheels.

Environmental conditions

Over the weekend, the rover was scheduled to also collect a large amount of data on current environmental conditions.

The team planned three Mastcam “tau” images, a Mastcam image of the crater rim, and a Navcam “Line of Sight” image, all of which will be used to quantify the amount of dust in the atmosphere, Baker reports.

A Navcam dust devil movie was also slated to be acquired, and four Navcam movies will help characterize cloud motion.

“So, although today’s plan is not necessarily typical for a weekend on Mars,” Baker concludes, the rover still had a full workload.

China’s space station development is heading for the next stage of assembly, and upon completion later this year, more space missions are expected to be carried out in the future.

China announced on Sunday it will send its next spaceflight crew to the Tiangong space station in June following the successful return of the three astronauts of the Shenzhou-13 mission on Saturday.

Complete construction

The China National Space Administration plans to complete the construction of the China Space Station in 2022 by adding the Wentian Experiment Capsule-1 and the Mengtian Experiment Capsule-2 to the Tianhe Core Module. Two Tianzhou cargo spacecraft will provide supplies for the astronauts of the Shenzhou-14 and Shenzhou-15 crew spacecraft.

The Wentian lab module will be launched in July and Mengtian in October, Hao Chun, director of the China Manned Space Agency, said at the press conference.

The Shenzhou-14 crew will witness the arrival of two lab modules during their stay in orbit.

The Shenzhou-15 crew will fly to the space station before the end of this year and join the Shenzhou-14 crew in space. At that time, the space station will consist of three modules, two manned spacecraft and one cargo spacecraft, with a total mass of nearly 100 tons.

Training and preparation

The two crews of the Shenzhou-14 and Shenzhou-15 have been selected and they are actively carrying out relevant training and preparation.

“The two crews of the Shenzhou-14 and Shenzhou-15 will stay in orbit for six months respectively, and they will carry out in-orbit rotation for the first time. The six astronauts will stay together in orbit for 5 to 10 days,” said Huang Weifen, chief designer of the astronaut system under China’s manned space program.

Mechanical arm 

“Once the space station is completed, astronauts will carry out experiments in space science, space materials, space medicine and space exploration in the two experimental modules. The experimental modules, together with the core module, can also support the life of six astronauts when the two manned spacecrafts dock with the space station,” said Yang Hong, chief designer of the space station under China’s manned space program.

In addition, a small mechanical arm can be used alone or in combination with the large mechanical arm of the core module to jointly complete tasks such as space extravehicular activities, and maintenance and inspection of extravehicular experimental equipment,” said Yang.

China also plans to launch the country’s first space telescope named Xuntian next year to conduct wide-field sky surveys.

Xuntian, or Surveying the Sky, will fly alongside the Tiangong station.

“The telescope will conduct frontier scientific research in the universe’s formation and evolution, dark matter and dark energy, exoplanets and solar system objects, and is expected to secure a batch of major innovative breakthroughs,” said Hao.

NASA’s Curiosity Mars rover at Gale Crater is now performing Sol 3446 duties.

“The curious case of cross-cutting ridges,” reports Sean Czarnecki, a planetary geologist at Arizona State University in Tempe, Arizona.

The rover has been focusing on examination of the linear ridges that cross-cut the local terrain.

“These raised ridges look like boxes with their lids cut off and mostly buried in the local bedrock, and all we can see are the vertical box faces sticking up out of the ground,” Czarnecki adds. How these structures actually form is an active area of investigation, and Mars researchers hope the data gathered will help them “think outside the box” and shed some light on their origin.

A recently scripted plan includes use of the Alpha Particle X-Ray Spectrometer (APXS) and the Mars Hand Lens Imager (MAHLI) on the target “Dun,” Chemistry & Camera (ChemCam) Laser Induced Breakdown Spectroscopy (LIBS) of “Ceres” (a target on Mars, not the dwarf planet!), and producing a ChemCam Remote Micro-Imager (RMI) mosaic of the Gediz Vallis ridge.
