Wonders All Around: The Incredible True Story of Astronaut Bruce McCandless II and the First Untethered Flight in Space by Bruce McCandless III; Greenleaf Book Group Press; 284 pages; Hardcover: $24.95.
We have all seen that iconic image – an astronaut in a snow-white spacesuit, untethered and floating free above Earth. Bruce McCandless II made that milestone-making, Buck Rogers-like space cruise in 1984 during his shuttle mission: STS-41B. As a mission specialist, McCandless controlled his movement above the Earth – and just few meters away from the space shuttle Challenger – during the first-ever spacewalk which didn’t use restrictive tethers and umbilicals.

This book is a wonderful read, written by his son, Bruce McCandless III. It is a very human tale, one that underscores the astronaut’s perseverance, setback, defeat and redemption.
The book features 22 chapters, including an excellent set of notes.
Astronaut McCandless joined NASA in 1966. He was the youngest of the new astronauts selected that year. He was chosen to be Houston’s capsule communicator for Apollo 11’s Neil Armstrong and Buzz Aldrin when they first set foot on the Moon. An astronaut for 24 years, he went on to help design, deploy, and later repair the Hubble Space Telescope.
His son writes: “He was an engineer, a true son of science, a distant nephew of Sir Isaac Newton. He knew the formulas required for achieving orbital velocity, could tell you the fuel mixtures you needed, the stages and timing of rocket-booster separations.”
Former NASA astronaut Bruce McCandless II, mission specialist on the STS-41B and STS-31 missions, passed away on Dec. 21, 2017, at the age of 80.

The author adds his thoughts when viewing that classic image of his father suspended in the cosmos, “the ant and the ocean.”
“But I see something else in the picture as well. I see the man who named me. He’s shut off from me now, mute and unattainable, sealed up in his pressure suit, as much a mystery to me in this vision as he ever was. As much a mystery as any man is to his son, who spends his life reading the clues a father left behind and remembering his words as he tries, a hundred times, to invent his own life. I don’t remember all those words, but I do hear one. It resonates to this day. Onward.”

Work is underway on the International Space Station to receive Russia’s new Nauka Multifunctional Laboratory Module.
The Nauka Module is set for a ride atop a Proton-M booster on July 21.
Meanwhile, crewmembers on the ISS are preparing the Pirs Module for undocking from the Russian segment of the ISS. Pirs is to be undocked from the ISS by the Progress MS-16 cargo vehicle on July 23, then ditched into the Pacific Ocean some 4 hours later.
Pirs module: years of use
Roscosmos cosmonauts Oleg Novitskiy and Pyotr Dubrov worked together with ground controllers to split the hydraulic circuit and docking unit control communications through the Progress MS-16 cargo vehicle, and checked the docking unit and its systems. After that, the crew took readings from all systems and assemblies of the module.

The Pirs Module was launched from the Baikonur Cosmodrome on September 15, 2001; the hardware was docked to the nadir port of the Zvezda Service Module of the ISS Russian Segment. Over the years, Pirs has been used as an additional berthing port for the Soyuz crewed and Progress cargo spacecraft, as well as an airlock for spacewalks under the Russian program.
The Pirs Docking Compartment consists of a sealed hull and features equipment, service systems and structural elements that ensure spacewalks. The outer side of the hull is covered with thick protection panels and screen-vacuum thermal insulation.
Two active and passive docking nodes are located along the longitudinal axis of Pirs. The active docking node is designed for sealed connection with the Zvezda Service Module. The passive docking node on the opposite side is designed for sealed connection with the Soyuz and Progress ships.

At the Baikonur Cosmodrome, active preparations are underway for the July 21 liftoff of the Nauka Module.
Roscosmos has published a Nauka Multifunctional Laboratory Module logo. The module is depicted in its operational configuration: with the European Robotic Arm (ERA) manipulator deployed, open porthole, and an airlock. The Russian tricolor encircling the module is referring to its origin. The name of the module (НАУКА) “science” is placed along the circumference of the emblem together with the year of its launch, the launch site (БАЙКОНУР, the Baikonur Cosmodrome) and the Proton-M carrier rocket (ПРОТОН-М) to take it into near-Earth orbit.

One concept is the Hexacopter, advocated as a way to greatly expand the exploration zone on Mars – including possible deep dives into Martian caves. Technologists have already gleaned loads of technical information from Ingenuity, steadily pushing its capabilities. Now they want to use that data to push for development of a new aerial system for Mars investigation.

The first batch of lunar samples retrieved by China’s Chang’e-5 mission were distributed on Monday to domestic scientific research institutions.
The samples were picked up from the Moon in December 2020 by the Chang’e-5 lunar probe, the first lunar soil sample collection brought back to Earth in more than four decades. The probe returned with 1,731 grams of lunar soil.
More than 17 grams worth of lunar samples brought back by the Chang’e-5 probe were distributed to 13 institutions, including the Chinese Academy of Sciences, China University of Geosciences (Beijing), China University of Geosciences (Wuhan), and the Sun Yat-sen University.

Under the microscope
The lunar soil seen by the naked eye is like dry black sand, but with finer grains. But under the microscope, it is a whole different view.
“This is the lunar soil, the original sample under the microscope that has not been crushed or polished. We can see many rock pieces in the view, which should be part of basalt. After its disintegration, some pieces still retain their original mineral composition, which we call debris. They are just physically smaller but their structure and mineral composition remain the same as the basalt. For other rock pieces, they actually turned into monominerals, that different types of minerals are separated. You can see the yellow ones in the view are generally olivine, brown ones are usually glass, white are normally plagioclase, and some dark ones are generally pyroxene. These are the main mineral components in basalt,” said Li Chunlai, deputy chief designer of the third phase of lunar exploration project, also chief engineer of the ground application system.

Physical fragmentation
Li told China Central Television (CCTV), unlike the soil on the Earth’s surface, the particles of the lunar soil are relatively small due to the influence of many factors.
“The environment on the Moon’s surface is very harsh. The temperature could reach about 160 degrees Celsius when the sun is shining and drop to minus 180 degrees Celsius when there is no sunlight. With a temperature difference of about 340 degrees Celsius, the rocks constantly undergo thermal expansion and contraction which result in disintegration. This is one factor. Another factor is that the Moon’s surface could be hit by many celestial bodies. The impact could cause physical fragmentation of the rocks,” Li said.
And since the Moon has no magnetic field at present, the solar wind can directly bombard the rocks on the Moon’s surface, which gradually result in the breakdown or even powdering of the rocks.
“The particles could measure a few tenths of a micrometer, a few millimeters or even centimeters. But on average, they are less than 10 microns, which is very, very broken. This is inconsistent with our original cognition and also different from the Apollo sample. It is a very fine lunar soil sample,” said Li.

Ensure safety of samples
Liu Jizhong, director of the Lunar Exploration and Space Program Center under the China National Space Agency (CNSA) told CCTV: “Our lunar sample management rules have clear provisions that part of the samples will be used for scientific research and part will be used for public good. After the preliminary study is completed and the re-study would yield little results. We then display them for the public good, letting more people to know more about the Moon.”

In order to ensure the safety of the lunar samples, the CNSA is planning to store up some lunar samples in Shaoshan, central China’s Hunan Province, in preparedness against disasters.
“We plan to distribute the samples as much as possible for scientific studies. We must also retain some for future sustained studies. We have a base for ex situ conservation of some samples. All these serve as the basic for following up studies,” said Liu.

The Impact of Lunar Dust on Human Exploration, Edited by Joel S. Levine; Cambridge Scholars Publishing; 303 Pages; January 2021; Hardcover: £64.99.
As humans prepare to replant their boots on the Moon, a major lesson from NASA’s Project Apollo is that dealing with lunar dust turned out to be a dilemma. For one, Lunar Module lander descent rockets caused large amounts of surface dust to move into the thin lunar atmosphere, causing obscuration of the lunar surface. That made touchdowns difficult and dangerous.
Moreover, once out and about, moonwalkers coped with very fine, tiny particles composed of sharp, glassy material. Indeed, lunar dust stuck to everything it came in contact with; dust eroded their spacesuits, caused overheating on equipment and instrumentation, compromised seals on their spacesuits and on lunar sample collecting boxes, as well as irritated the eyes and lungs of moonwalkers.
This excellent volume summarizes what we know about lunar dust, its structure and chemical composition, its impact on human health, and how to reduce/mitigate its effects on future human exploration. The four dozen contributors to the 14 chapters in the book are planetary scientists, engineers, mission planners, medical researchers and physicians from NASA and the European Space Agency (ESA), as well as universities and industry from the United States, Australia, Germany, Italy, the Netherlands, Portugal and Sweden.
Rich in detail, the reader will find a treasure trove of lessons from Apollo and a look ahead to what future expeditions will face. There’s a bounty of data here, be it the history and future perspectives for the evaluation of the toxicity of celestial dust to lunar dust mitigation strategy and testing through simulation and analogs.
Editor Joel S. Levine is a research professor in applied science at the College of William and Mary, USA, and a consultant to NASA’s Engineering and Safety Center at the NASA Langley Research Center in Hampton, Virginia. This compilation of excellent and fact-filled papers is a must-have for researchers and general readers too.

NASA’s Curiosity Mars rover at Gale Crater is now performing Sol 3173 tasks.
The rover is working with the latest drill sample from the 32nd hole on Mars, “Pontours.”
Ken Herkenhoff, Planetary Geologist at the USGS Astrogeology Science Center in Flagstaff, Arizona, reports that the robot’s Chemistry & Mineralogy X-Ray Diffraction/X-Ray Fluorescence Instrument (CheMin) assessed some of the drill sample.
The CheMin team decided to dump the sample and clean out the cell in preparation for future mineralogical analyses, Herkenhoff adds.
Curiosity’s Sample Analysis at Mars (SAM) Instrument Suite was to undergo preconditioning to analyze the Pontours drill sample.

Weekend workout
“Once the path forward was agreed upon and the high-priority CheMin and SAM activities scheduled, the uplink team turned to planning other activities, of which there are many,” Herkenhoff notes.
On Sol 3173, Mastcam is set to acquire multispectral images of “Chanterac,” a potential Alpha Particle X-Ray Spectrometer (APXS) target, before the robot’s Chemistry and Camera uses its laser to analyze the wall of the Pontours drill hole and acquires spectra of freshly disturbed sand at “Cendrieux.”

The rover’s Mastcam is documenting the Laser Induced Breakdown Spectroscopy (LIBS) holes in Pontours, Herkenhoff reports, and take a 12×2 stereo mosaic of fractured and lineated terrain dubbed “Le Coly.”
Finally, CheMin is set to dump the drill sample.
Nodule target
Also on tap, Sol 3174 observations with Navcam searching for dust devils and measuring dust in the lower part of the atmosphere.
Then Mastcam is to acquire a 10×1 stereo mosaic of possible alteration features at “Bussac” before ChemCam uses LIBS again, this time on a bedrock block with lots of nodules called “Archignac.”

ChemCam will also acquire spectra of another nodular target called “Fergeas” and the Right Mastcam will document the LIBS spots on Archignac. The rover will then take a nap before the SAM preconditioning in the evening, Herkenhoff points out.
A Sol 3175 plan begins with a Navcam dust devil movie and Mastcam measurements of dust in the atmosphere above the rover.
ChemCam will then fire its laser again, this time at “Augignac,” another nodular bedrock target, followed by Right Mastcam documentation of the LIBS spots.
Mt. Sharp layering
Later in the afternoon, when lighting of targets east of the rover will be better, the ChemCam Remote Micro-Imager (RMI) will take a 10×1 mosaic of layering in the flank of Mt. Sharp.

Mastcam will then acquire a 4×1 stereo mosaic of the layering, and Navcam will survey the sky.
“Early in the morning of Sol 3176, Navcam will search for clouds and again measure the dust in the lower part of the atmosphere. Finally, Mastcam will also measure dust at various levels in the atmosphere,” Herkenhoff concludes. If all goes well, Curiosity will be very busy this weekend!

As the countdown approaches for suborbital liftoffs of entrepreneurs Jeff Bezos and Sir Richard Branson, and their independent space travel enterprises, I asked author Alan Ladwig to reflect on these upcoming milestones. Ladwig is a former manager of both the Shuttle Student Involvement Program and the Spaceflight Participant Program, which included the Teacher in Space and Journalist in Space competitions.
In July of 2008 when Virgin Galactic rolled out the WhiteKnight2 carrier aircraft, Richard Branson said the first suborbital passenger flights would take place in 2010. Space dreamers have been waiting patiently, (some not so patiently) for Virgin to deliver the goods.

Now, 11 years past that initial promise, this historic milestone will finally be achieved with Branson on board.
Just 11 days later, Blue Origin will also debut its first flight with passengers on board, including no less than the richest man in the world, Jeff Bezos.

Recreational space travel
After years of being promised that our ticket to ride was just a rocket away, the dream of recreational space travel for “ordinary citizens” has arrived.
The long 11 years that it took to get here will be quickly forgotten as dozens of people achieve their dream to see Earth from above. Though often criticized as a playground for the ultra rich, in the years ahead an increasing number of travelers of more modest means will check in at the launch pad to conduct science and engineering research and testing, perform educational programs, and create entertainment endeavors. And some people will go that just want to have fun.

Speaking at a space conference in 1990, Cosmonaut Alexsandr Serebrov observed, “Those who fly in space feel differently and become sick with a global philosophy and terrible case of cosmic views.”
During these extraordinarily challenging political times, let’s hope those who are able to make the trip into space come back and confirm Serebrov’s proclamation.

Russia’s Nauka laboratory module is now slated for launch on July 21.
A Roscosmos statement said the new module for the International Space Station will be launched from Site 200 of the Baikonur cosmodrome atop a Proton-M carrier rocket. Backup dates are July 22, and July 23.
The module’s flight to the ISS will take 8 days, docking at the nadir port of Russia’s Zvezda service module.
Undocking of the Progress MS-16 cargo vehicle with the Pirs docking module is scheduled for July 23 (subject to the Nauka launch on July 21).

Prelaunch prep stage
At the Baikonur Cosmodrome, Roscosmos states, routine preparations of the Nauka module are underway for the upcoming launch. Currently, the ascent unit is at the fueling and neutralization station, the most important operation of the final prelaunch preparation stage.
The Nauka Laboratory Module is a research module of the Russian segment of the ISS, developed by RSC Energia together with Khrunichev Center (part of Roscosmos). This module is designed to expand the functionality of the Russian segment of the International Space Station.

Added safety of ISS crew
“The Nauka module was created on the constructive and technological basis of the Zarya Functional Cargo Block employing the experience of designing a transport supply vehicle for the Salyut crewed scientific stations and modules for retrofitting the Mir orbital complex,” the Roscosmos statement adds.
“After the commissioning of the new module, the Russian segment will receive additional volumes for the workplaces and storage of cargo, places for water and oxygen regeneration equipment, improve the conditions of cosmonauts’ stay, as well as increase the safety of the entire ISS crew,” the statement concludes.

Cherry-picker crane
The European Robotic Arm (ERA) will be launched to the ISS together with the Nauka. ERA will work with the new Russian airlock, to transfer small payloads directly from inside to outside the ISS. This will reduce the set-up time for astronauts on a spacewalk and allow ERA to work alongside astronauts.
Another task for ERA is to transport astronauts like a cherry-picker crane to a position where they can work on the exterior of the ISS, or from one external location to another. This again saves time and effort during spacewalks.
ERA is 100% made-in-Europe. A consortium of European companies led by Airbus Defense and Space Netherlands designed and assembled it for the European Space Agency (ESA). The robotic arm is largely funded by the Dutch government.
