See You In Orbit? – Our Dream Of Spaceflight by Alan Ladwig, To Orbit Productions, LLC, October 2019; paperback, 500 pages, $18.00.

Public space travel is soon getting a boost from Richard Branson’s Virgin Galactic and the efforts of the Jeff Bezos-backed Blue Origin. Plunking down cash to skyrocket into near-space heights and escape velocity vacationing in Earth orbit is in the offing. Or is it?

Strap in, place your table trays into locked position and enjoy a highly revealing read from author Alan Ladwig, 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.

See You in Orbit? is a superb, fact-filled account of the on-going promise of commercial space tourism, and pulls no punches about why it has been such a long, drawn-out countdown to reality.

Ladwig at the outset of the volume admits the book has been “a crime of passion for over three decades.” The reader will be consumed by that zeal contained within 13 chapters that begins with the dreams of yesterday and concludes with wagons ho and way beyond Earth’s boundaries. Within that sweep of reading, I myself was drawn to the author’s behind-the-scenes account of the loss of Challenger and its crew that included teacher-in-space, Christa McAuliffe – subtitled “The Dream Turns into Heartbreak.”

Footloose and fancy-free, author Alan Ladwig.

Ladwig has an engaging, witty, and often poignant writing manner that adds to the reader’s page-turning experience. The author is no stranger to zero-gravity, having experienced hundreds of parabolas on ZERO-G’s G-Force 1 and NASA’s KC-135. That said, he confesses that the thought of being confined in a small capsule gives him the willies. “Trust me, you wouldn’t want me sitting in the middle seat next to you,” he writes.

The book includes an extensive chapter-by-chapter notes section, clearly demonstrating the author’s exhaustive research in writing this enlightening and instructive volume.

Be it “The Scent of Musk” or “Space Cycler Built for Two” or “How Many Billionaires Does It Take to Get Us to Space?”…these and other quips guide the reader to a wisdom-filled smooth touchdown.

NASA’s Curiosity Mars rover is now closing out Sol 2586 science duties.

Reports Claire Newman, an atmospheric scientist at Aeolis Research, Curiosity is again at the “Hunda” facies, high up on Central Butte.

“At this location, we’re finding a lot of decimeter-scale laminations – sequences of fine layers – near to and underneath the rover,” Newman explains.

Float rock

In these layers, target “Kirkcudbrightshire” was chosen as the location for first Chemistry and Camera (ChemCam) then Alpha Particle X-Ray Spectrometer (APXS) analysis, the idea being that ChemCam Laser Induced Breakdown Spectrometer (LIBS) would remove any dust covering the target before the APXS contact science overnight.

A second APXS target “Foggy Moss” was chosen to sample the float rock found here, which was already analyzed using ChemCam in a prior sol.

“Here ‘float’ refers to the piece of rock having been transported from its original outcrop, and this one might represent the cap rock of the entire butte,” Newman adds.

Edge of rock ledge

More ChemCam LIBS analyses were planned on targets “Kincardineshire,” which may sample the edge of the rock ledge, “Grogsport,” another bedrock target higher in the section (to test how chemistry, especially sulfate content, changes with position), and “Hog Burn,” another float rock which might also represent the capping unit and can be compared with Foggy Moss, Newman points out.

Mastcam mosaics and ChemCam documentation images, Newman continues, were used to place all of these measurements in context, and the geology side of the plan finished with Mastcam stereo of layers in the outcrop (“Bonny Braes”), as well as a Mastcam context mosaic of additional outcrop, allowing the various mosaics from this location to be linked together (“Bonnie View”).

Dog’s eye mosaic

Also planned are Mars Hand Lens Imager (MAHLI) images of Kirkcudbrightshire and Foggy Moss, and a MAHLI ‘dog’s eye’ mosaic of target “Sourhope”; the latter means that the arm will be positioned so MAHLI looks sideways (rather than down) at the target, Newman notes, to get a better view of the laminations within the rocks.

On the environmental side of the plan, Mars rover scientists included the usual Rover Environmental Monitoring Station (REMS) monitoring of atmospheric and surface temperature, surface pressure, humidity, and UV radiation, plus Dynamic Albedo of Neutrons (DAN) passive and active monitoring of the subsurface composition, and the ongoing continuous Radiation Assessment Detector (RAD) monitoring of energetic particle radiation.

Cloud altitude, dust devils

“We’re in the cloudy season right now, so we added in a Navcam Cloud Altitude Observation which uses observations of clouds and their shadows, plus geometry, to work out cloud heights,” Newman reports. “This is a valuable piece of information for inferring the vertical structure of the crater’s atmosphere, as cloud height is related to both water abundance and the thermal profile.”

Also added to planning is a Navcam Dust Devil Survey at about 4:20pm local true solar time. “This is a few hours later than we expect most dust devils to occur, especially in winter, based on both theory and past observations,” Newman observes.

“However, we’ve observed dust devils this late in the day in other seasons, and it’s important to repeat these surveys at a range of times in every season each year, rather than assuming nothing will change as we move up the slope! Finally, we measured the amount of dust above us and the visibility across the crater at two times of sol using Mastcam, and measured the across-crater visibility at one time of sol with Navcam also,” Newman concludes.

China’s Longjiang-2 spacecraft (also known as DSLWP-B) crashed onto the lunar farside on July 31, 2019 after completing its orbital mission. NASA’s Lunar Reconnaissance Orbiter (LRO) has spotted the apparent impact site.

The Longjiang-2 satellite was launched to the Moon along with the Queqiao relay communications satellite on May 20, 2018 by the China National Space Agency (CNSA). The small spacecraft – weighing nearly 100 pounds (45 kilograms) — was designed to work with its twin (Longjiang-1) to validate technologies for low-frequency radio astronomy observations.

Impact result

According to Mark Robinson, leader of the LRO Lunar Reconnaissance Orbiter Camera (LROC) at Arizona State University, a new lunar crater has been identified and most likely the result of that impact.

In a posting, Robinson saluted the team led by amateur radio operator, Daniel Estévez of Tres Cantos, Spain, that estimated the small spacecraft impacted somewhere within Van Gent crater (16.69°N, 159.52°E).

Careful comparison

The LROC team used these coordinates to image the area on October 5, 2019. Through a careful comparison of pre-existing LROC Narrow Angle Camera (NAC) images, the LROC team was able to locate a new impact crater (16.6956°N, 159.5170°E, ±10 meters), a distance of only 328 meters from the estimated site!

The crater is 13 feet (4 meters) by 16 feet (5 meters) in diameter, with the long axis oriented southwest to northeast.

Based on proximity to the estimated crash coordinates and the crater size, “we are fairly confident that this new crater formed as a result of the Longjiang-2 impact,” Robinson notes.

China has unveiled a simulated Mars landing facility, making use of a tower nearly 460 feet (140 meter) in height, a testing structure situated at Huailai County, Hebei Province, north China. The six pylon tower facility included a servo system and a Martian surface simulation area.

The highly touted test is prelude to China launching the country’s Mars probe in 2020, aiming to complete orbiting, landing and roving in one mission, according to the China National Space Administration.

The experiment simulated the gravity of Mars, about one-third of the gravity on Earth, to test the design of the lander, according to China Central Television (CCTV).

Ambassadors and diplomats from 19 countries including France, Italy and Brazil, as well as representatives from the European Union, the African Union and the Asia-Pacific Space Cooperation Organization were invited to watch the experiment, said CCTV.

Landing procedure

In a Xinhua news agency story, Zhang Rongqiao, chief designer of China’s first Mars exploration mission, said in order to simulate the landing procedure under the gravitational acceleration of Mars demanded construction of the facility.

A red platform in the middle of the pylons is fixed by 36 steel cables. Through precise control, Xinhua reports, the platform is able to simulate the Martian gravitational environment.

On the ground underneath the pylon tower, engineers created slopes and craters to mimic the environment of the Martian surface.

Obstacle-avoiding mode

According to Xinhua, Thursday’s test verified the procedures including the lander’s separation with the main body of the spacecraft from a 70-meter altitude, and then hovering at 67 meters above the surface, searching for a safe landing spot, and then descending to 20 meters above the surface in an obstacle-avoiding mode.

Zhang Kejian, administrator of the CNSA, said since the official kick-off in 2016, China’s Mars exploration program has progressed well. The hovering and obstacle avoidance test for the Mars lander is a crucial step of the project, Xinhua reports.

Leading UFO researcher, Stanton Friedman.

If you are sky-eyed and hooked by “UFO-ology,” a leading spokesperson on the topic was nuclear physicist and lecturer Stanton T. Friedman.

As a scientist that had a serious interest in flying saucers since 1958, he will be missed by researchers given his untimely death in May of this year at the age of 84.

Extensive work

I met Friedman several times over the years, and found him captivating and a believable UFO investigator. His legacy lives on…thanks to the Provincial Archives of New Brunswick, Canada.

Stanton Friedman donated his invaluable research papers to the archive – a donation that filled five cargo vans, explains Joanna Aiton Kerr of the archives.

“Due to the volume of the material and the need to do extensive work to make it available to researchers it would probably take about 10 years with the resources we currently have available to focus on it,” Kerr told Inside Outer Space.

“In a perfect world, we would have two archivists working on it and nothing else full time,” Kerr said, [and] if that happened it would still take two to three years – there is that much of it.”

Archival pressure

Kerr said that the records are so interesting, and the interest from the public is such that the archive feels the pressure and need to make sure that they do everything as quickly as they can…”but it also needs to be done right!”

Records are available to researchers as they are processed, Kerr added. “However we are not digitizing – this would be a mammoth task and frankly pointless until the actual paper/photographs, etc, are physically organized and listed.  Otherwise it would just be a big digital mess.”

The challenge

Friedman had posted in December 1997 that he had reached four major conclusions, under the title of “The UFO Challenge”:

— The evidence is overwhelming that Planet Earth is being visited by intelligently controlled extraterrestrial spacecraft. In other words, SOME UFOs are alien spacecraft. Most are not.

— The subject of flying saucers represents a kind of Cosmic Watergate, meaning that some few people in major governments have known since July, 1947, when two crashed saucers and several alien bodies were recovered in New Mexico, that indeed SOME UFOs are ET. As noted in 1950, it’s the most classified U.S. topic.

— None of the arguments made against conclusions One and Two by a small group of debunkers such as Carl Sagan, my University of Chicago classmate for three years, can stand up to careful scrutiny.

— The Flying Saucer story is the biggest story of the millennium: visits to Planet Earth by aliens and the U.S. government’s cover-up of the best data (the bodies and wreckage) for over fifty years.

Public defense

“Stan Friedman’s most important contribution was his vigorous and intellectually sound public defense of the continuing mystery of the UFO phenomenon, the utter failure of science to recognize this, and thus the need for a serious sustained scientific investigation,” explains Mark Rodeghier, Scientific Director of the J. Allen Hynek Center for UFO Studies.

“His most important research was done on government documents and on the fabled Roswell UFO crash, which he demonstrated is not easily explained,” Rodeghier told Inside Outer Space.

Scientists at NASA’s Johnson Space Center (JSC) in Houston, Texas have opened untouched samples brought back from the Moon during the Apollo era.

The rock and soil samples will be studied as part of the Apollo Next Generation Sample Analysis (ANGSA) initiative, which is leveraging advanced technologies to study Apollo samples by using new tools that were not available when the samples were originally returned to Earth.

Nerve-wracking

Rutgers University scholar Juliane Gross was one of three women scientists who opened the pristine Apollo 17 sample on November 5th. Apollo 17 moonwalkers collected the lunar specimens in December 1972.

“It was such a humbling experience to be part of this and totally nerve-wracking because we couldn’t make any mistakes,” said Gross, an associate professor at Rutgers in the Department of Earth and Planetary Sciences in the School of Arts and Sciences. “But it was absolutely mind-blowing and so exciting at the same time.”

Gross said in a Rutgers University statement that it was hard and awkward to open and extrude the core sample. The reason: “everything had to be done inside a nitrogen-gas filled glovebox and we wore big gloves that made it hard to feel and grab tools,” Gross said. “But we had practiced a lot with a practice glovebox, so we worked really well together and all went smoothly with opening and extruding the core.”

New insights

The ANGSA multigenerational and multidisciplinary team will systematically examine samples 73002 and 73001, part of a two-foot long “drive tube” of regolith, collected by astronauts Harrison Schmitt and Gene Cernan from a landslide deposit near Lara Crater at the Apollo 17 site.

“The findings from these samples will provide NASA new insights into the Moon, including the history of impacts on the lunar surface, how landslides occur on the lunar surface, and how the Moon’s crust has evolved over time,” adds Chip Shearer, science co-lead for ANGSA in the Lunar Curation Laboratory at NASA’s JSC and a visiting scientist at the Lunar and Planetary Institute (LPI). “This research will help NASA better understand how volatile reservoirs develop, evolve and interact on the Moon and other planetary bodies, in an LPI statement.
