WASHINGTON — NASA formally certified SpaceX’s Crew Dragon spacecraft for transporting astronauts to and from the International Space Station, clearing the way for a Nov. 14 launch.

Agency officials completed the certification of the spacecraft by signing a document known as a Human Rating Certification Plan during a flight readiness review for the Crew-1 mission Nov. 10. That confirmed that SpaceX met all of NASA’s requirements for safely carrying astronauts on the Crew Dragon spacecraft and Falcon 9 launch vehicle.

“It’s just a tremendous day that is a culmination of a ton of work,” said Kathy Lueders, NASA associate administrator for human exploration and operations, at a Nov. 10 briefing about the flight readiness review. Lueders managed the commercial crew program at NASA for several years before being promoted to her current position in June. “It’s NASA saying to SpaceX you have shown us you can deliver a crew transportation capability that meets our requirements.”

A Chinese team has demonstrated a prototype of a microwave plasma thruster capable of working in the Earth’s atmosphere and producing thrust with an efficiency comparable to the jet engines you’d find on modern airliners – under laboratory conditions.

Plasma thrusters are already operational on spacecraft as a means of solar-electric locomotion, using xenon plasma, but such things are no use in the Earth’s atmosphere, as accelerated xenon ions lose most of their thrust force to friction against the air. Not to mention, they only make a small amount of thrust in the first place.

The idea of terraforming Mars is a fascinating idea. … But just how long would such an endeavor take, what would it cost us, and is it really an effective use of our time and energy?

Ultimately, Yakovlev thinks that space biospheres could also be accomplished within a reasonable timeframe – i.e. between 2030 and 2050 – which is simply not possible with terraforming. Citing the growing presence and power of the commercial space sector, Yakovlev also believed a lot of the infrastructure that is necessary is already in place (or under development).

“Anything you take from Earth to the moon is an added weight that you don’t want to carry, so if you can make these materials in situ it saves you a lot of time, effort and money,” said Ian Mellor, the managing director of Metalysis, which is based in Sheffield.

Analyses of rocks brought back from the moon reveal that oxygen makes up about 45% of the material by weight. The remainder is largely iron, aluminium and silicon. In work published this year, scientists at Metalysis and the University of Glasgow found they could extract 96% of the oxygen from simulated lunar soil, leaving useful metal alloy powders behind.

NASA and other space agencies are in advanced preparations to return to the moon, this time to establish a permanent lunar base, or “moon village” where nations will operate alongside private companies on critical technologies such as life support, habitat construction, energy generation and food and materials production.

CAPE CANAVERAL, Fla. (AP) — Four astronauts arrived at Kennedy Space Center on Sunday for SpaceX’s second crew launch, coming up next weekend.

For NASA, it marks the long-awaited start of regular crew rotations at the International Space Station, with private companies providing the lifts. There will be double the number of astronauts as the test flight earlier this year, and their mission will last a full six months.

“Make no mistake: Every flight is a test flight when it comes to space travel. But it’s also true that we need to routinely be able to go to the International Space Station,” NASA Administrator Jim Bridenstine said in welcoming the astronauts to Kennedy.

This could mean breathable oxygen and rocket fuel. Not only that, they are suggesting the metal alloy byproducts could be useful again. Interesting.

I think a colony on the moon is sounding a bit more feasible.

The European Space Agency has created an experimental “oxygen plant” in the Netherlands that can extract oxygen trapped within simulated Moon dust.

NASA is flying astronauts to the International Space Station from the United States using commercial vehicles.

On Nov. 14, the first operational mission of this program, NASA’s SpaceX Crew-1 mission, is set to launch four astronauts on SpaceX’s Crew Dragon vehicle.

Watch as the crew explains what their mission is, how it is different from Bob Behnken and Doug Hurley’s Demo-2 flight, and what it means for people here on Earth. https://www.nasa.gov/crew-1

Richard Branson, the thrill-seeking British billionaire, founded Virgin Galactic in 2004 on the promise that a privately developed spacecraft would make it possible for hundreds of people to become astronauts, no NASA training required. And if a 2,500-mile-per-hour ride to the edge of space sounded off-putting, Branson also pledged to take the journey himself before letting paying customers on board.

Branson is the only one among the group of the so-called space barons, the group of space-loving billionaires that includes Elon Musk and Jeff Bezos, who has publicly pledged to take a ride in the near future aboard a spacecraft he has bankrolled.

Bezos’ company, Blue Origin, is working on a competing suborbital space tourism rocket. Musk’s SpaceX, however, is focused on transporting astronauts and perhaps one day tourists on days-long missions to Earth’s orbit.
