Did ancient astronomers set a message in stone for us?
by Sam Dinkin Tuesday, July 6, 2021

Back in 2003, The Space Review first started repeating the story of the danger of large impacts (“Asteroids are probably a threat. Maybe?” The Space Review, September 9, 2003). It is possible we are recapitulating a tradition that started more than 11,000 years before present (BP). Ancient astronomers may have provided us with a report about what may be “the worst day ever in human history” according to Martin B. Sweatman and Dimitrios Tsikritsis (“Decoding Göbekli Tepe with Archaeoastronomy: What does the fox say?”, 2017).

The nanosatellite gold rush demands new routes to space
by Steve Heller Tuesday, July 6, 2021


A SpaceX Falcon 9 launched 88 small satellites last week, but rideshare missions like this should be complemented by other means to easily and affordably get smallsats into orbit. (credit: SpaceX)

More than six decades since the launch of Sputnik 1, the first satellite in history, nanosatellites have opened up a new era in private space innovation. They’ve created a wealth of new opportunities for upstart satellite developers, and new challenges to solve for those who seek to help them make their impact.

Flights to Mars, real and LEGO
by Dwayne A. Day Tuesday, July 6, 2021


In 1968, Boeing produced a detailed study of a human mission to Mars. Now somebody has produced the spacecraft using LEGO. Here it is in two different scales. (credit: Joe Chambers)

In early 1968, The Boeing Company delivered to NASA a thick, multi-volume report on how to send humans to Mars. That report, titled “Integrated Manned Interplanetary Spacecraft Concept Definition,” described a large, nuclear-powered spacecraft that would be launched in components atop Saturn V rockets, and after assembly in orbit would head off to the Red Planet. Boeing’s Mars spacecraft design concept was further refined by NASA in 1969 and would become iconic for the next decade and a half, appearing in artwork and on book covers and in the pages of novels until it was replaced by another concept for a human mission to Mars that resulted from the Case For Mars conference and was often referred to as the “Mars Cycler.” That Mars spaceship design entered the zeitgeist for another decade or so. But Boeing’s design has shown remarkable staying power and still appears in artwork decades later. Now, Boeing’s design has been recreated in LEGO form, in three-dimensional plastic glory that you can build yourself.

Ingenuity, InSight, and Ice Mapper
by Jeff Foust Tuesday, July 6, 2021

It is a golden era for rovers on Mars. For the first time, there are now three operating rovers on the Red Planet. Curiosity has been at work for nearly nine years now, working its way up Mount Sharp in the center of Gale Crater and traveling through time as it studies different rock layers there. Perseverance, which landed on Mars in February, is ramping up its science operations in Jezero Crater, including plans for caching samples for later return to Earth. And China’s first Mars rover, Zhurong, is exploring the Utopia Planitia region of the planet, although Chinese officials have provided few details since its May landing beyond some images and videos.

Review: Across the Airless Wilds

Monday, July 12, 2021



Across the Airless Wilds: The Lunar Rover and the Triumph of the Final Moon Landings
by Earl Swift
Custom House, 2021
hardcover, 384 pp., illus.
ISBN 978-0-06-298653-5
US$28.99
https://www.amazon.com/exec/obidos/ASIN/0062986538/spaceviews

In late May, Lockheed Martin announced it was partnering with General Motors on concepts for future lunar rovers. Executives with the aerospace and automotive giants said they would combine the best technologies of both companies, such as GM’s work on batteries and autonomous driving, for future NASA competitions to develop lunar rovers for the Artemis program. Beyond that, though, there were few details about how the two companies will work together, in part because NASA has yet to release any requests for proposals to develop lunar rovers.

When it comes to spacewalks, size matters
by Steven Moore Monday, July 12, 2021

On June 25, astronauts Shane Kimbrough and Thomas Pesquet successfully completed an almost seven-hour EVA (extravehicular activity, or spacewalk) to install solar panels on the International Space Station, the last in a series of three such EVAs they performed in June. What does it take to don a spacesuit and venture out on such a technical and dangerous mission? Surprisingly, one of the main criteria (besides the years of astronaut training) is body size.

China is using mythology and sci-fi to sell its space program to the world
by Molly Silk Monday, July 12, 2021


The movie The Wandering Earth is one example of how China is using science fiction to shape perceptions of its space ambitions. (credit: Netflix)

On the morning of June 17, China launched its long-awaited Shenzhou-12 spacecraft, carrying three Chinese astronauts, or taikonauts, towards the Tianhe core module. The module itself was launched at the end of April, forming part of the permanent Tiangong space station, which is planned to remain in orbit for the next ten years.

The suborbital spaceflight race isn’t over
by Jeff Foust Monday, July 12, 2021

It was never a race, Branson insisted. Not that anyone believed him.

Branson was sitting on a stage in a temporary building adjacent to the main hangar at Spaceport America in New Mexico, a couple of hours after making his long-awaited and highly anticipated suborbital journey on SpaceShipTwo on Sunday. He and other members of the “Unity 22” crew faced the media for a press conference where one reporter, unsurprisingly, asked him what it felt like to beat Jeff Bezos, founder of rival Blue Origin, to space.

Review: Leadership Moments from NASA
by Jeff Foust Monday, July 19, 2021



Leadership Moments from NASA: Achieving the Impossible
by Dave Williams and Elizabeth Howell
ECW Press, 2021
hardcover, 328 pp.
ISBN 978-1-77041-604-8
US$19.95
https://www.amazon.com/exec/obidos/ASIN/1770416048/spaceviews

Over the course of more than six decades, NASA has provided plenty of examples of leadership, good and bad. Many of those cases are well known even outside the agency, from the successful return of the Apollo 13 astronauts to the losses of Challenger and Columbia. There are, though, many more events within the agency, at large and small scales, that can provide insights on management and leadership.

Assessing and celebrating the global impact of the “First Lady Astronaut Trainees”
by James Oberg Monday, July 19, 2021


Jerrie Cobb (left), one of the “Mercury 13” women, meets with Valentina Tereshkova, the first woman in space. The Mercury 13 testing effort helped prompt the Soviets to fly Tereshkova.

This month’s “billionaire’s space race” drama portends a very interesting future of more private citizen access to space, first on brief up-and-down hops and soon after on full orbital expeditions. Previous episodic very-high-priced space tourist missions will give way to much more frequent and much less expensive jaunts.

Astronomy flagships, past and future
by Jeff Foust Monday, July 19, 2021

Sometimes it’s the missions that are behind schedule. Other times it’s the reports about the missions that are behind schedule.

For months, the astronomy community in the United States has been eagerly awaiting the final report of the astrophysics decadal survey, known as “Astro2020.” As the name suggests, the study originally expected to publish its final report in 2020 (the previous astrophysics decadal survey report was released in August 2010.) Even before the pandemic, though, it appeared likely the final report would not be ready until the beginning of 2021, a schedule further delayed by the shift to virtual meetings and deliberations since last spring.

Flattops from space: the once (and future?) meme of photographing aircraft carriers from orbit
by Dwayne A. Day Monday, July 19, 2021


The cover of Jane’s Defence Weekly in 1984 that featured reconnaissance satellite imagery of a Soviet carrier under construction.

In 1984, Samuel Loring Morison, an analyst at the Naval Intelligence Support Center outside of Washington, DC, picked three photos off the desk of a colleague. He clipped the security classification stamps off the sides of the photos and provided them to Jane’s Defence Weekly, which had only recently begun publishing. The photos were taken by a satellite of a Soviet Union military shipyard. Knowing that they had a real scoop, the editors at Jane’s put one of the photos on the cover of the magazine and featured the other two in a short article about the latest Soviet naval developments.

Review: The Burning Blue
by Jeff Foust Monday, July 26, 2021



The Burning Blue: The Untold Story of Christa McAuliffe and NASA’s Challenger Disaster
by Kevin Cook
Henry Holt and Co., 2021
hardcover, 288 pp., illus.
ISBN 978-1-250-75555-1
US$27.99
https://www.amazon.com/exec/obidos/ASIN/1250755557/spaceviews

Depending on your age, the loss of the shuttle Challenger more than 35 years ago can either seem like it happened yesterday or feel like it’s ancient history. If you’re old enough to remember the tragedy, the memories run deep and can come bubbling back to the surface with just the slightest mention. For anyone younger than about 40, though, who lack the first-hand memories of the event, the events lose their visceral, emotional punch.

With the successful suborbital flights this month by Blue Origin and Virgin Galactic, space is now wide open to not just professional astronauts but just about anyone. Or, rather, anyone wealthy enough to afford a ticket. And that’s a problem.

John Glenn’s fan mail and the ambitions of the girls who wrote to him
by Roshanna P. SylvestervMonday, July 26, 2021


John Glenn, seen here in the NASA mailroom after his 1962 spaceflight, received letters from fans of all ages. (credit: John Glenn Archives, The Ohio State University)

Pioneering spacefarer John Herschel Glenn Jr. would have turned 100 on July 18. When Glenn died in 2016, the famed astronaut was lauded as “the last genuine American hero.” NASA, the US Marine Corps, President Barack Obama, and many others posted tributes on social media.

Hundreds of nostalgic fans testified to Glenn’s impact on their own senses of youthful possibility. One woman recalled being a fifth grader in February 1962, listening to coverage of Glenn’s orbital flight at school on a transistor radio: “This was the definition of the future… I wanted to do hard math with slide rules and learn hard languages and solve mysteries. I wanted to be like John Glenn.”
