The Gateway Foundation is a private company that claims they could build the first orbital space hotel by 2025. According to their site, the Von Braun Rotating Space Station is designed "to accommodate both national space agencies conducting low gravity research and space tourists who want to experience life on a large space station with the comfort of low gravity and the feel of a nice hotel" large enough for 450 visitors. From Space.com:

Gateway Foundation officials acknowledge that the station might not be entirely finished by 2025, but the group aims to develop the station's main structure and basic functions by then. "We expect the operation to begin in 2025, the full station will be built out and completed by 2027. … Once the station's fully operational, our hope, our goal and our objective is to have the station available for the average person," (lead architect Timothy) Alatorre said. "So, a family or an individual could save up reasonably … and be able to have enough money to visit space and have that experience. … It would be something that would be within reach...

Alatorre said that the Gateway Foundation feels that such a project is now possible because the growing success of commercial aerospace companies like SpaceX has made launch options more affordable.

He added that the company admits that it's possible its timeline is pushing it somewhat. "We completely understand that delays are almost inevitable with aerospace, but based on our internal projections and the fact that we're already dealing with existing technology, we're not inventing anything new.

Yesterday, a satellite smaller than a shoebox unfurled a solar sail making it the first spacecraft to orbit the Earth powered by sunlight. LightSail2 is a project of the Planetary Society, a fantastic nonprofit organization co-founded by astronomer and science educator Carl Sagan. From the New York Times:

For centuries, it was only a dream: traveling through space propelled by the sun’s photons. It was first imagined in the 1600s by Johannes Kepler, the German astronomer who described the laws of the planets’ orbits. In 1964, Arthur C. Clarke moved it into the realm of science fiction in “Sunjammer,” a short story. Carl Sagan, the cosmologist, believed it could be more than a speculative fantasy, and in the 1970s began promoting the building of solar sails for space exploration.

After 10 years of planning and over 40,000 private donations worth $7 million, that idea took flight on Tuesday, as LightSail 2, a spacecraft built for the Planetary Society, co-founded by Mr. Sagan, began what its creators hope will be a year of sailing around Earth.

“This is still one of the most feasible pathways to have real interstellar space travel in the future,” said Sasha Sagan, a writer as well as the daughter of the astronomer.

If it succeeds in its mission, it will contribute to overcoming one of the greatest limitations on the outer bounds of space travel — that the power that steers spacecraft, usually hydrazine fuel, eventually runs out.

In Technology Review, author and essayist Chuck Klosterman delivers a short introduction to the stars of space rock, from Pink Floyd (above) to Hawkwind to Spacemen 3:

Space is a vacuum: the only song capturing the verbatim resonance of space is John Cage’s perfectly silent “4'33".” Any artist purporting to embody the acoustics of the cosmos is projecting a myth. That myth, however, is collective and widely understood. Space has no sound, but certain sounds are “spacey.” Part of this is due to “Space Oddity”; another part comes from cinema, particularly the soundtrack to 2001 (the epic power of classical music by Richard Strauss and György Ligeti). Still another factor is the consistent application of specific instruments, like the ondes martenot (a keyboard that vaguely simulates a human voice, used most famously in the theme to the TV show Star Trek). The shared assumptions about what makes music extraterrestrial are now so accepted that we tend to ignore how strange it is that we all agree on something impossible.

The application of these clichés is most readily seen in the dawn of heavy metal. The 1970 Black Sabbath song “Planet Caravan” processed Ozzy Osbourne’s vocals through a Hammond organ to create a sprawling sense of ethereal distance. Deep Purple’s 1972 “Space Truckin’” used ring modulation to simulate a colossal spacecraft traveling at high speed. The lyrical content of Led Zeppelin’s “No Quarter” is built on Norse mythology, but the dreamlike drone of John Paul Jones’s mellotron and Jimmy Page’s ultra-compressed guitar mirrored the sensation of exploring an alien landscape.

NASA announced today that the International Space Station is now open to private astronauts for commercial business and, yes, tourism. It ain't budget travel, that's for sure. Kenneth Chang writes in the New York Times:

NASA is not selling space vacations directly, but allowing commercial companies to arrange such trips. The agency plans to charge the companies about $35,000 a night for use of the station’s facilities, including air and water.

The tourist companies would charge much more to cover the rocket flights to and from space, and to make a profit.

Bigelow Aerospace of North Las Vegas, Nev., has already reserved four launches. The company will use SpaceX, the rocket company run by Elon Musk, to take private astronauts. Each flight would have four seats.

Axiom Space of Houston is also arranging flights and hopes to fly tourists next year.

From NASA:

Pricing released Friday is specific to commercial and marketing activities enabled by the new directive, reflects a representative cost to NASA, and is designed to encourage the emergence of new markets. As NASA learns how these new markets respond, the agency will reassess the pricing and amount of available resources approximately every six months and make adjustments as necessary.

To qualify, commercial and marketing activities must either:

• require the unique microgravity environment to enable manufacturing, production or development of a commercial application;

• have a connection to NASA’s mission; or

• support the development of a sustainable low-Earth orbit economy.

NASA’s directive enabling commercial and marketing activities aboard the space station addresses manufacturing, production, transportation, and marketing of commercial resources and goods, including products intended for commercial sale on Earth.

NASA astronaut Anne McClain captured this astonishing image of the SpaceX Crew Dragon capsule approaching her temporary residence, the International Space Station. "The dawn of a new era in human spaceflight," McClain tweeted with the photo.

The SpaceX Crew Dragon, containing supplies rather than humans for this test, docked at the ISS yesterday morning and the hatch was opened a few hours ago. From NASA:

(The mission, called) Demo-1 is the first flight test of a space system designed for humans built and operated by a commercial company through a public-private partnership. The mission also marks a significant step toward returning to the nation the capability to launch astronauts on a U.S.-built spacecraft from U.S. soil.

“It’s an exciting evening,” NASA Administrator Jim Bridenstine said after the launch. “What today really represents is a new era in spaceflight. We’re looking forward to being one of many customers in a robust commercial marketplace in low-Earth orbit.”
