A handful of the Galactic Sandbox team and friends had the privilege to witness the total solar eclipse last month from a front-row perch in the Idaho Rockies. Below are a few photos of the experience, including an exclusive shot of the totality by filmmaker and photographer John Zibell who was with us (note, the planet Mercury can be seen at about 8 o’clock from the Sun/Moon), and partial eclipse pix taken by yours truly.
As we stood agog over the spectacularly silent celestial show, it wasn’t hard to understand how such an event has made an indelible impression on humanity for thousands of years, and how little we’ve scratched the surface of our wondrous universe. It was also hard not to think of how our dear friend Kate Woods would have loved to have been there — in a just cosmos, she should not only be in a place looking up to the stars, but looking out from them! — Agnett Bonwitt

While the human and economic toll from Hurricane Harvey continues to (rightfully) remain as a top concern for rescue and relief efforts as well as the focus of media attention, the general public may forget that NASA’s mission control is headquartered in besieged Houston. According to Space News, Johnson Space Center was drenched with 42 inches of rain last week, and through Labor Day is being manned by a skeleton crew to monitor International Space Station operations. In addition, the space agency’s next-generation, $8.8 billion James Webb Space Telescope that is scheduled to launch late next year, has been at JSC for testing and while the building it’s being housed at was flooded, the telescope fortunately remains unscathed.
Quick Editorial Aside: Obviously, the recent flooding – not only in the Gulf Coast, but also the catastrophic deluge which has left over a thousand dead and one third of Bangladesh under water – if not directly caused by climate change, does offer a chilling preview of things to come if Trump and his cronies continue to willfully and greedily turn their backs from the ability of humankind to survive a greenhouse gas-choked Earth.
Days of Future Past
As many US citizens continue to reel from the political, environmental, and cultural devastation that has reached a possible point of no return with the Trump administration, ultimately we can’t say that we weren’t warned of such an Orwellian scenario. Making the internet rounds lately is an excerpt from a 1996 Carl Sagan book, “The Demon Haunted World,” in which Sagan paints an eerily familiar picture of our present time:
“I have a foreboding of an America in my children’s or my grandchildren’s time — when the United States is a service and information economy; when nearly all the key manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what’s true, we slide, almost without noticing, back into superstition and darkness. The dumbing down of America is most evident in the slow decay of substantive content in the enormously influential media, the 30-second sound bites (now down to 10 seconds or less), lowest common denominator programming, credulous presentations on pseudoscience and superstition, but especially a kind of celebration of ignorance.”
Sagan also provides a warning that applies all too fittingly to our orange-tinted sociopath-in-chief: “Once you give a charlatan power over you, you almost never get it back.”
In July, Elon Musk’s Space X commercial space venture passed the $20 billion valuation mark.
Investors’ appetite for commercial space ventures continued to be ravenous in 2016, according to newly-compiled data from industry consulting group Bryce Space and Technology that reported a record-smashing $2.8 billion in more mainstream capital thrown at out-of-this-world projects last year – a $400 million increase since 2015. And while the SpaceXs and Blue Origins continue to be the darlings of the burgeoning sector, it is a new generation of small, relatively inexpensive satellites beaming terabytes of data to Earth that have venture capitalists drooling over the potential returns on everything from the satellites themselves, to software used to interpret their data, and from the new rockets designed to boost them into orbit. “Fundamentally, investors go after opportunity, and the way I would sum it up is, this is one of the last frontiers, to be a little cliché,” said Tom Barton, chief operating officer at Planet, whose 190 imaging birds grind out 7 terabytes of new Earth imagery each day. “It’s still old-school; it hasn’t really been touched by Moore’s Law,” Barton told CNBC.
In 2016, 114 investors poured more than $2.8 billion into space start-ups. Above satellite imagery produced by commercial space firm, Planet.
However, according to authors of the Bryce study, the industry has advanced to the point that investors are anxious to see a return on dollars, not just pie-in-the-sky dreams. “We’re not yet seeing the outcome of investment in a lot of funded companies,” said Bryce’s CEO Carissa Christensen. “We’re seeing their ability to raise money, we’re seeing their ability to design and deploy their systems, but we’re not seeing their ability to return profits,” she added. It’s also a make or break time for many start-ups which according to Planet’s Barton, could go bankrupt in the next few years. “As much as I say that we’re at the start of consolidation in the new space sector, I think we’re probably at the start of some of these companies going bankrupt,” Planet’s Barton says, adding, “I would guess that over the next two years we see five or 10 significant bankruptcies or acquisitions for pennies on the dollar for people that just aren’t going to make it on their own.”
US astronaut Peggy Whitson returned to Earth last weekend from the International Space Station, breaking the record of cumulative days in space for any American or any woman worldwide. According to Phys.org, Whitson’s homecoming aboard a Russian Soyuz capsule at a desolate region of Kazakhstan early Sunday morning local time marked 665 days in orbit, with 288 days for her just-completed mission. As well as time marked in space, Whitson broke past a few other milestones: world’s oldest spacewoman, at age 57; the most experienced female spacewalker with 10; and the first woman to command the ISS twice.
The largest asteroid in more than a century to cruise safely pass Earth reached within 4.4 million miles our planet on Friday as professional and amateur astronomers stampeded optical and radio telescopes to get a detailed glimpse of the mountain-sized space rock that last visited our neck of the solar system in 1890. Nicknamed “Florence” after nursing pioneer Florence Nightengale, the 3 mile-wide boulder provided scientists with a celestial living room view of an object we usually have to send multi-million dollar spacecraft to chase down and study. And in fact a team of researchers operating the humongous radar-equipped dishes at NASA’s Goldstone tracking station in California and Arecibo Observatory in Puerto Rico took advantage of Florence’s lumbering speed and discovered that it has two moons, each estimated at 300 to 1000 feet across.
Asteroid 2012 TC4’s path past Earth.
In a related story, on October 12, researchers will have a rare opportunity to assess Earth’s “planetary defense” systems – or lack thereof – when a house-sized asteroid travels harmlessly by our planet at a distance of only an eighth of that between us and the Moon. “It’s damn close,” said Rolf Densing, who heads the European Space Operations Center in Darmstadt, Germany as he commented on the hair’s-breath 27,300 miles the wayfaring space rock dubbed 2012 TC4 will approach before continuing its path into the void of space. Observing TC4’s movements “is an excellent opportunity to test the international ability to detect and track near-Earth objects and assess our ability to respond together to a real asteroid threat,” said an ESA statement.
Keeping the Dream Alive
Sierra Nevada’s mini-me “Dream Chaser” space shuttle completed a “captive carry” test above the Mojave Desert in California at NASA’s Armstrong Flight Research Center, as part of a significant step toward returning American-made civilian winged spacecraft to orbit by 2020. While the Colorado-based firm lost out to Boeing and SpaceX to ferry astronaut crews to the international space station, NASA approved Sierra Nevada’s development of a dwarfed, robotically-piloted spaceplane that will deliver supplies to the orbiting station. “Today was a great accomplishment on Sierra’s planned march towards doing that approach and landing test,” said Mike Lee of NASA’s Commercial Crew Program, which is led from Kennedy Space Center, following the captive carry test. Their are at least two launches of the reusable Dream Chaser slated from Cape Canaveral atop United Launch Alliance’s Atlas V rocket.
Relatedly, the Air Force’s fifth X-37B Orbital Test Vehicle (OTV) mission is slated for launch this Thursday aboard a SpaceX Falcon rocket, and will carry an Advanced Structurally Embedded Thermal Spreader payload that will study the long-durational exposure of experimental electronics and oscillating heat pipe technologies in space, reports Space Daily. “It is our goal to continue advancing the X-37B OTV so it can more fully support the growing space community,” said Randy Walden, director of the Air Force’s Rapid Capabilities Office. The uncrewed X-37B space plane completed its fourth mission last May, landing after 718 days in orbit and extending the total number of days off the Earth to 2,085.
Scientists are scratching their heads over the origin of 15 recently-recorded radio bursts from a galaxy 3 billion light years away that have ignited a barrage of sensational headlines speculating that the mysterious signals could have been produced by an alien civilization. A UC Berkeley-based team employing the Green Bank Telescope in West Virginia caught the ancient radio beacons on August 26 and reported their initial findings as an Astronomer’s Telegram that can be read here. The California researchers are part of the Breakthrough Listen project, a global astronomical initiative launched in 2015 by Internet investor and philanthropist Yuri Milner and famed cosmologist Stephen Hawking to “observe nearby stars and galaxies for signatures of extraterrestrial technology.”
According to recent Hubble Telescope findings, out of the 7 Earth-sized Trappist-1 planets located 40 light years away, the inner two worlds could have lost more than 20 Earth-oceans-worth of water during the last eight billion years, while the outer planets, including e, f and g which are in the habitable zone should have lost much less moisture, suggesting that they could have retained enough H2O for habitable life.
Another report that sent news outlets in a tin foil hat tizzy involve findings by an astronomy team using the Hubble Space Telescope suggesting that the outer Earth-sized planets orbiting the recently-discovered Trappist-1 solar system might still harbor substantial amounts of water, making them prime candidates for habitable life. Swiss astronomer Vincent Bourrier, lead researcher of the squad that studied the effects that ultraviolet rays from the Trappist dwarf star have on breaking up water vapor on its now famous seven planetary offspring, noted that information garnered by our our current scientific instruments is insufficient to draw final conclusions on how wet these planets are. “While our results suggest that the outer planets are the best candidates to search for water with the upcoming James Webb Space Telescope, they also highlight the need for theoretical studies and complementary observations at all wavelengths to determine the nature of the TRAPPIST-1 planets and their potential habitability,” Bourier said.
Clap Traps – Tin Foil Hat Pusher Alert!
Over the past week or so, there has been an avalanche of news items covering the above puzzling radio bursts and Trappist-1 water stories that range from a mild ding to a full-blown, circus clown horn blast on our Tin Foil Hat meter, suggesting, and in some cases unabashedly asserting, that these inconclusive cosmic observations involve proof that alien civilizations exist. One of the more blatant offenders was the UK’s Daily Star that laughingly proclaimed the following:
As if this error-laced screamer weren’t bad enough, scattered throughout the actual “story” like IQ-reducing buckshot were unsubstantiated (and grammatically incorrect) claims such as “Scientist find [sic] evidence aliens could have been living on Trappist for billions of yea [sic],” and “more than 40,000 Americans have taken out insurance against being abducted by aliens,” While all of this is neither surprising or new, it does show that Carl Sagan’s prophesied “celebration of ignorance” continues to rage at a fevered pitch. Tin Foil Hats all around!
