Stoke Space gets to use John Glenn’s launch pad

Kent, Wash.-based Stoke Space says it’s won the go-ahead to take over the Florida launch complex where John Glenn began the trip that made him the first American in orbit in 1962.

That’s the upshot of the U.S. Space Force’s decision on Tuesday to allocate Space Launch Complex 14 at Cape Canaveral Space Force Station to Stoke Space for use as a launch operations center.

“We are over the moon excited by this opportunity,” Julia Black, Stoke Space’s director of launch operations, said in a news release. “To be trusted with the reactivation of the historic Launch Complex 14 is an honor, and we look forward to adding to its well-distinguished accomplishments for America’s space program.”

Space Launch Delta 45, which manages Cape Canaveral’s launch facilities, said the allocation is part of a new Space Force strategy to maximize the use of excess launch property and the Eastern Range extending from the Florida coast.

Novelist charts a course for the future space frontier

If Jeff Bezos needs a blueprint for building a space station beyond the moon with ore from an asteroid, he just might want to start with “Critical Mass,” a newly published sci-fi novel by Daniel Suarez.

The 464-page book describes in detail how entrepreneurs, engineers and astronauts take advantage of a cache of material mined from an asteroid to create a giant, ring-shaped space station, a space-based solar power system, a mass driver for delivering resources from the moon and a nuclear-powered spaceliner. To add to the drama, they’re doing all this in the midst of a global climate crisis in the late 2030s.

Building space outposts and moving heavy industry off-Earth to preserve our home planet’s environment is an overarching theme in Bezos’ long-term space vision. “We want to go to space to save the Earth,” he said in 2016. “I don’t like the ‘Plan B’ idea that we want to go to space so we have a backup planet. … This is the best planet. There is no doubt. This is the one that you want to protect.”

Suarez agrees with Bezos’ sentiment, but not because the billionaire founder of Amazon and Blue Origin came up with the idea.. In the latest episode of the Fiction Science podcast, Suarez points out that Princeton physicist Gerard K. O’Neill, Bezos’ space mentor, had the idea first. “This is the idea of settling deep space by re-creating our biosphere in free space as opposed to settling another planet,” he says.

With “Critical Mass” and the other books in his Delta-V trilogy, Suarez aims to do what O’Neill’s 1970s-era mix of science fiction and fact, “The High Frontier,” did for the likes of Jeff Bezos. Suarez aims to get people thinking about how a space-based society could work.

Japanese team joins high-flying balloon tourism race

A Japanese company has put out the call for passengers who’d be willing to pay more than $175,000 for an hours-long ride in a balloon-borne capsule that will rise as high as 15 miles (25 kilometers).

Technically, that’s nowhere near the boundary of outer space, but it’s high enough to get an astronaut’s-eye view of the curving Earth beneath a black sky.

“It’s safe, economical and gentle for people,” the CEO of a startup called Iwaya Giken, Keisuke Iwaya, told reporters in Tokyo. “The idea is to make space tourism for everyone.”

Other companies are planning similar stratospheric tourist ventures. But if Iwaya’s venture sticks to its announced timeline and begins flying customers around the end of this year, it would be the first to get to market.

Microsoft backs effort to extend fiber internet in Africa

Microsoft says it’s partnering with a fiber-cable connectivity venture called Liquid Intelligent Technologies to bring high-speed internet access to an additional 20 million people in Africa by 2025.

The collaboration is part of Microsoft’s Airband Initiative, which aims to help extend broadband coverage to 250 million people living in unserved and underserved areas of the world, including 100 million people in Africa.

Microsoft President Brad Smith announced the partnership with Liquid in advance of the Fifth U.N. Conference on the Least Developed Countries, which gets underway next week in Doha, Qatar. Microsoft will co-chair the meeting’s Private Sector Forum.

“The private sector can plan an important role in creating opportunities for the 880 million people living in LDCs [least developed countries], where only 36% of the population uses the internet today, and it’s important for Microsoft to do its part,” Smith said in a blog posting.

Study documents satellite interference with Hubble

An analysis of more than 100,000 images from the Hubble Space Telescope, conducted with the aid of artificial intelligence and hundreds of human volunteers, confirms that satellites including SpaceX’s Starlink spacecraft are increasingly interfering with astronomical observations.

The images used in the study, which is the subject of a paper published today by Nature Astronomy, largely predate the deployment of Starlink broadband internet satellites. But the trend line suggests that more and more satellites will cause more and more interference.

“This is an attempt to define a baseline before the swarm of artificial satellites for future follow-up studies of the impact of megaconstellations on space-based astronomy,” said the research team, which is led by Sandor Kruk of the Max Planck Institute for Extraterrestrial Physics in Germany.

Hydrogen-powered plane aces its first flight

A prototype aircraft with a hydrogen-fueled powertrain successfully completed an initial 15-minute flight today at Grant County International Airport in Moses Lake, Wash., marking a significant step for zero-emission aviation.

Los Angeles-based Universal Hydrogen had the 40-passenger De Havilland Dash 8-300 turboprop converted to use hydrogen to power an electric propulsion system mounted on the plane’s right wing. The system incorporates a fuel cell built by Plug Power and a megawatt-class motor built by Everett, Wash.-based MagniX. Seattle-based AeroTEC assisted with the engineering for the conversion.

The engine on the left side was left unconverted to serve as a backup in case the hydrogen-based system encountered problems.

Universal Hydrogen and its partners worked in Moses Lake for months to get the plane — nicknamed Lightning McClean — ready for today’s first aerial tryout, conducted under the conditions of an experimental airworthiness certificate from the Federal Aviation Administration.

The flight began at 8:41 a.m. PT and reached a maximum altitude of 3,500 feet. “We were able to throttle back the fossil-fuel turbine engine to demonstrate cruise principally on hydrogen power,” test pilot Alex Kroll said in a news release. “The airplane handled beautifully, and the noise and vibrations from the fuel cell powertrain are significantly lower than from the conventional turbine engine.”

Hidden passage discovered within Egypt’s Great Pyramid

Archaeologists have discovered a long-lost passageway within Egypt’s 4,500-year-old Great Pyramid of Giza, thanks to 21st-century technologies including muon tomography and endoscopy.

It’s the latest find made possible with the help of ScanPyramids, an international effort that started documenting Egypt’s best-known archaeological sites with high-tech tools in 2015.

Over the past eight years, ScanPyramids’ team has identified several voids within the Great Pyramid. The passageway described today lies just beneath the pyramid’s north face, about 23 feet (7 meters) above the main entrance. It’s 30 feet (9 meters) long, about 7 feet (2.1 meters) wide, and high enough for a person to stand in.

A new type of salt crystal could exist on Europa

A prime target in the search for extraterrestrial life is Europa, a moon of Jupiter that’s covered with a sheet of salty ice. But what kind of salt is there? Researchers say they’ve created a new kind of salt crystal that could fill the bill, and perhaps raise hopes for finding life under the ice.

This salt crystal is both exotic and common: It’s actually table salt — also known as sodium chloride, with the chemical formula NaCl — but bound up with water molecules to form a hydrate that doesn’t exist naturally on Earth.

Earthly sodium chloride hydrates are composed of one salt molecule linked by hydrogen bonds with two water molecules. In contrast, the hydrates created in the lab consist of two NaCl molecules to 17 water molecules, or one NaCl molecule to 13 water molecules. (The structure for a third type of “hyperhydrated hydrate” couldn’t be determined.)

That’s promising news for scientists who study Europa and other ice-covered worlds — including two other Jovian moons, Callisto and Ganymede; and the Saturnian moons Enceladus and Titan. Spectral observations indicate that Europa’s surface ice contains salts, including sodium chloride, but the observed levels of concentration don’t match up well with Earth’s run-of-the-mill NaCl hydrates.

Presidential hair will be launched to deep space

If it turns out that a future extraterrestrial invasion force is headed by a clone of George Washington, we’ll have only ourselves to blame.

Admittedly, that would be the unlikeliest outcome of a space shot that aims to send hair samples from America’s first president — and from Presidents Dwight Eisenhower, John F. Kennedy and Ronald Reagan — into deep space.

The samples, which include bits of DNA, are to be included on Houston-based Celestis’ “Enterprise Flight,” a memorial space mission that will also carry DNA and cremated remains from the late astronaut Philip ChapmanStar Trek celebrities and scores of Celestis clients. The time capsule will be sent into space later this year as a secondary payload aboard United Launch Alliance’s Vulcan Centaur rocket, and eventually settle into stable orbit around the sun.
