NASA’s Curiosity Mars rover has just started Sol 2722 operations.

Lucy Thompson, a planetary geologist at University of New Brunswick, Fredericton, New Brunswick, Canada explains that the primary focus of a two-sol plan is to prepare the drill bit assembly to dump the remaining “Edinburgh” drilled sample (portion to exhaustion), so that it can be analyzed in the upcoming weekend plan with the Alpha Particle X-Ray Spectrometer (APXS) and Mars Hand Lens Imager (MAHLI) instruments for chemistry and texture respectively.

Sample delivery

Sample has successfully been delivered to both Curiosity’s internal Chemistry & Mineralogy X-Ray Diffraction/X-Ray Fluorescence Instrument (CheMin) and Sample Analysis at Mars (SAM) instruments, Thompson adds, and scientists are awaiting the results of the mineralogy and volatile/isotope chemistry, with the 3rd night of CheMin analysis in this plan.

“The Edinburgh sample represents the blocky, dark grey sandstone, pediment-capping unit that overlies the Murray mudstone,” Thompson reports.  Science team members are interested to see how the mineralogy and chemistry might differ between these two rocks types, given that they were likely deposited in different environments.

Curiosity reached the top of the slope March 6 (the 2,696th Martian day, or sol, of the mission). It took three drives to scale the hill, the second of which tilted the rover 31 degrees — the most the rover has ever tilted on Mars. This selfie was taken on Feb. 26, 2020 (Sol 2687). Since 2014, the robot has been rolling up Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain at the center of Gale Crater.

The priority for the recent sol 2720 plan was to drop off and analyze a sample of the Edinburgh drill hole in the Sample Analysis at Mars (SAM) Instrument Suite.

“But we’ve got plenty of remote sensing in the plan too, much of it building on our previous observations from this spot,” reports Ryan Anderson, Planetary Geologist at USGS Astrogeology Science Center in Flagstaff, Arizona.

Changes in weathering behavior

“We start each morning with a Navcam dust devil survey,” Anderson adds.

In the Sol 2720 plan, the robot’s Mastcam was to take a stereo mosaic of a nearby hilltop, extending a previous mosaic to look for changes in the weathering behavior of the pediment cap rock. This was to be followed by Chemistry and Camera (ChemCam) observations of two sandstone bedrock targets named “Tron Kirk” and “Dunedin” and extensions of two long-distance  Remote Micro Imager (RMI) telescope mosaics of the “washboard” surface of the pediment, Anderson explains.

Curiosity’s Mastcam was tasked to document the ChemCam targets, and then take some pictures of the SAM inlet before and after sample drop off.

Navcam also has an 8-frame movie toward the south to watch for atmospheric activity like clouds. The robot’s Alpha Particle X-Ray Spectrometer (APXS) then has an overnight atmospheric observation, Anderson notes. “Yes, APXS can measure the atmosphere too!”

Down the drill hole

On the Sol 2721 plan, ChemCam was slated to make a vertical measurement inside the Edinburgh drill hole.

“After Mastcam documents that observation,” Anderson concludes, “it will add some frames to its own mosaic of the washboard pattern on the pediment. Navcam will then take a picture toward the north to study the amount of dust in the atmosphere. The rest of sol 2721 will be taken up by SAM’s analysis of the Edinburgh sample.”

 

Soviet Space Graphics: Cosmic Visions from the USSR by Alexandra Sankova (in collaboration with the Moscow Design Museum), Phaidon; April 2020; Hardback; 240 pages, $39.95.

This book is a well-timed retro-fire into space history – and an absolute wonderful read.

The volume offers insight into the Soviet sociopolitical landscape, a behind-the-scenes view of how space played in the minds of space visionaries behind the Iron Curtain over the decades.

This is a book that offers a view of more than 250 covers and interior illustrations that depict first-time discoveries and scientific prowess, but laden with futuristic visions of where space exploration can take us.

Up front disclosure: I’m a relic from the impact of Cold War-era Russian space imagery. The space propaganda machine by the USSR was in full-throttle when I was much younger, as U.S. rockets and spacecraft seemed lost in space, missed their mark or crapped out on arrival.

Yes, America had its successes, but it was all high-drama and this book reflects the Space Race running full-steam. As this volume exemplifies, making use of the period’s hugely successful popular-science magazines, the imagery rocketed out of the Soviet Union were an essential tool for the endorsement of state ideology.

As explained in the book: “As the competition heated up, so did the response in the media. In the USSR, popular science magazines were a vital tool in the motivation and engagement of the general public, documenting in great detail and vivid color both the realities and fantasies of the state’s advancements on the West.”

This wonderful book features images from the surreal to the sublime, colored in communist sentiment. The magazine images portray the boldest of space exploration ideas – many of them alive and well even in the 21st century.

The volume is divided up into unique chapters, from Educate, Encourage, Dream to Cosmic Pioneers, Alternative Worlds and Future Visions. Lastly, there’s a very informative section on the magazines from which the book has drawn its captivating material.

Again, this is a unique and enjoyable read that deserves attention…not only for the reader to romp around in the past, but serves as a historic bookmark in pioneering the space frontier of today.

NASA’s Curiosity Mars rover is now performing Sol 2720 tasks.

“Curiosity’s drill campaigns are like poetry in fixed verse,” says Melissa Rice, a planetary geologist at Western Washington University in Bellingham, Washington.

A predefined set of activities has to occur in a sequence: first Curiosity must assess an outcrop for drilling, then drill and extract a sample, then process and characterize the sample, then deliver the sample to the robot’s Chemistry & Mineralogy X-Ray Diffraction/X-Ray Fluorescence Instrument (CheMin) instrument for analysis, then prepare the Sample Analysis at Mars (SAM) Instrument Suite, then deliver the sample to SAM for analysis, and finally dump the sample on the ground.

“All of this happens over a period of a couple weeks, and when we are planning the science observations for any given sol, we need to work within the scaffolding of the drill campaign sequence,” Rice notes. “But like poets crafting sonnets in iambic pentameter, we find freedom within the fixed structure to create something new.”

Second analysis of drill sample

Such was the case for a plan that covers sols 2717-2719.

“As Curiosity proceeds with the Edinburgh drill campaign, we use free blocks of time here and there to explore the landscape,” Rice reports. The main structure of this three-sol plan includes a second analysis of the Edinburgh drill sample with CheMin and the preconditioning of the SAM instrument to prepare for an upcoming Evolved Gas Analysis (EGA) observation.

The Center for Strategic and International Studies (CSIS) has issued a space threat assessment 2020 report.

This informative study notes that in the last year, more states are considering the development of offensive and defensive counterspace capabilities to protect space systems from attacks.

“Nations are moving to reorganize their national security space enterprise, as the United States did in 2019, to better address the growing uncertainty and threats in the space domain,” the report explains.

Clear indication in fog of war

Things to watch within the United States are updates to space doctrine, strategy, and policy and investments in new space capabilities and missions.

“Developments in these areas would be a clear indication that the reorganization efforts put in place in 2019 are part of a fundamental shift in the U.S. military’s overall approach to making space more defendable,” the report adds.

Researchers compared results of asteroid deflection simulations to experimental data.

Thwarting an incoming asteroid that has Earth in its crosshairs will mean deflecting or disrupting the hazardous object.

Already on the books is the Double Asteroid Redirection Test (DART) mission in 2021 – the first-ever kinetic impact deflection demonstration on a near-Earth asteroid.  

“We’re preparing for something that has a very low probability of happening in our lifetimes, but a very high consequence if it were to occur,” says Lawrence Livermore National Laboratory (LLNL) physicist Tané Remington. “Time will be the enemy if we see something headed our way one day. We may have a limited window to deflect it, and we will want to be certain that we know how to avert disaster.”

DART mission schematic shows the impact on the moonlet of asteroid (65803) Didymos. Post-impact observations from Earth-based optical telescopes and planetary radar would, in turn, measure the change in the moonlet’s orbit about the parent body.

DART mission

The findings of a new study by Remington and colleagues is titled “Numerical Simulations of Laboratory‐Scale, Hypervelocity‐Impact Experiments for Asteroid‐Deflection Code Validation.” The work identified sensitivities in the code parameters that can help researchers working to design a modeling plan for the DART mission.

The DART mission is being developed and led for NASA by the Johns Hopkins University Applied Physics Laboratory. NASA’s Planetary Defense Coordination Office is the lead for planetary defense activities and is sponsoring the DART mission.

The DART spacecraft will launch in late July of 2021. The target is a binary (two asteroids orbiting each other) near-Earth asteroid named Didymos that is being intensely observed using telescopes on Earth to precisely measure its properties before impact.

The DART spacecraft will deliberately crash into the smaller moonlet in the binary asteroid – dubbed Didymoon – in September of 2022 at a speed of approximately 6.6 km/s.

The collision will change the speed of the moonlet in its orbit around the main body by a fraction of one percent, but this will change the orbital period of the moonlet by several minutes – enough to be observed and measured using telescopes on Earth.

Code confidence

But understanding how multiple variables might affect a kinetic deflection attempt relies upon large-scale hydrodynamic simulations thoroughly vetted against relevant laboratory‐scale experiments.

However, do we know our codes are correct?

The new study investigated the accuracy of the codes by comparing simulation results to the data from a 1991 laboratory experiment conducted at Kyoto University in Japan where a hypervelocity projectile impacted a basalt sphere target.

“In an effort to gain confidence in our codes, this work compares our simulation results to data from a well‐known laboratory‐scale experiment to assess the accuracy of our models,” the LLNL planetary defense research team explains. “We find that our code can produce results that closely resemble the experimental findings, giving assurance to the planetary defense community that our code can correctly simulate asteroid or comet mitigation.”

Momentum transfer

“This study suggests that the DART mission will impart a smaller momentum transfer than previously calculated,” said Mike Owen, LLNL physicist, coauthor on the paper and developer of the “Spheral” code – an adaptive smoothed-particle hydrodynamics code.

“If there were an Earthbound asteroid, underestimating momentum transfer could mean the difference between a successful deflection mission and an impact. It’s critical we get the right answer. Having real world data to compare to is like having the answer in the back of the book,” Owen says in a LLNL statement.

Bye-bye, miss american pie: The U.S. Congress and President Trump have sealed a $2 trillion+ stimulus deal stimulated by the on-going COVID-19 crisis that’s impacted all aspects of the U.S. economy, including America’s civil space program.

Let’s layer those transmissible woes on top of projected NASA intentions to shape a human return to the Moon by 2024 – and shoving off to Mars as a future objective.

That’s the background for reaching out to two key space policy gurus in Washington, D.C.

What now?

“Setting the end of 2024 for getting back to the Moon was always arbitrary,” explains John Logsdon, Professor Emeritus of Political Science and International Affairs at the Space Policy Institute, Elliott School of International Affairs at George Washington University in Washington, D.C.

“With the current health crisis situation and the stand down of the Artemis team, it makes absolutely no sense to continue to push for that date,” Logsdon told Inside Outer Space.

A much more fundamental issue, Logsdon added, “is whether the White House, the Congress, and indeed the U.S. public will continue, as we emerge from this trauma, to support human space exploration in the face of unprecedented demands on the government budget.”

The big ask

Requesting $71 billion over the next five years to go back to the Moon by 2024, a politically-inspired date, on top of everything else NASA does, was a big ask to begin with, says Marcia Smith, founder and editor of SpacePolicyOnline.com.

“In the current climate, with trillions – that’s with a t – being spent to keep the country afloat economically, I think it will be a bridge too far,” Smith told Inside Outer Space.

“Generally speaking, Congress loves NASA, and space exploration, so I don’t think the goal will change, but almost certainly the timeline,” Smith said.

NASA’s Curiosity Mars rover is currently performing Sol 2717 tasks.

At last report, the Edinburgh drill campaign continues.
