Small steps for space settlements

In decades, space advocates have pushed space liquidation: human beings live and work permanently over the Earth. These visions are grouped into different forms, based on the Moon and Marsen, Gerard K. O & # 39; Neille espoused spatial colonies for over 40 years ago. But over these decades, these are just the same views: concepts that have been largely kept in fantasy.

"They are not the simple things, but the things that are accelerating are happening, and I think this is a very exciting one," said Pittman.

These dream space settlements, though, may come a bit closer to reality. SpaceX's efforts to reduce start-up costs and defend efforts by Elon Musk as early as 2020 to go to Martxa. Jeff Bezos has a similarity to the Blue Origin, even more than with O & # 39; Neillian rather than with Musk's view of space rather than Musk's viewpoint. Even though NASA combines with the general concept the "sustainable" plan of its excitement that will increase international and commercial capabilities.

"They are not the simple things, but the things that are accelerating are happening, and I think that's so exciting," said Bruce Pittman, vice president of the National Space Society.

Pittman spoke at the NSS Space Settlement Summit, a two-day event at the University of Los Angeles in early November. This event could ultimately lead to the development of a long-term vision of space settlement.

Not surprisingly, there has been a lot of talk about the achievements and plans in space access. One Panel called "What should we do to 150 Tons Orbit?" Is a reference to the ability of SpaceX to launch the next generation system, known as the Big Falcon Rocket or BFR. (Last week, Musk announced on Twitter, of course, the lower and booster stage of the vehicle called "Super Heavy" and a higher "space" stage called "Starship").

"If you have a full re-use of this type of vehicle and billions of dollars per flight, I think it will transform everything that is going to be used for space," said Dan Rasky, director of Space Portal Office at the Ames Research Center at NASA. It compared the effect of the Transcontinental railroad, the time it crossed the country, the cost fell and the security improved. "It was totally transformative, and when things seemed like that it suddenly became commonplace in that place. I think that space may be on the verge."

SpaceX is not alone: ​​for example, Blue Origin's work and the Air Force Launch Service Awards were held in October to help Blue Origin's New Glenn fund development, as well as the United Launch Alliance's Vulcan Centaur and Northrop Grumman's OmegA rockets too. .

"Space has been linked to the idea of ​​being a very difficult and expensive idea," Rasky said. "If we see these barriers lower the income significantly, what could happen?"

The desire to return to the moon was also renewed, in order to defend the firmness, especially due to the presence of ice resources. "The Moon propeller would reduce the cost of Earth and Earth's surface by means of three factors," said George Sowers, professor at the Resource Center in the Mineta Colorad School. "I think it's the next step".

Sowers, the most important "Space Policy" (SPD) 1, was signed by President Trump at the end of December, which requires Dark Moon to return. The language of this directive, that is to say, the commercial and international cooperation for permanent rotational feathers, unlike the space exploration initiative and space exploration, will be different at this time.

"Jim Bridenstine is the best NASA manager in terms of what we expect," said Hopkins.

"For the first time in a very long time, we have a coherent and executable strategy that is happening in the area of ​​administration," said Greg Autry, a USC professor at the NASA transitional team. Trump administration after 2016 elections.

There were no members of the NASA board of directors, but Jim Bridenstine's NASA administrator recorded short annotated statements in the event. "We share the vision of creating lifelong living space and living space in space," he said before talking about NASA's exploration plans.

These words were musicians' ears. "Jim Bridenstine is the best administrator of the NASA in terms of what we expect," said Mark Hopkins, NSS Executive Committee President.

It was not everyone who persuades us to be different at this time. "There are good words in it, and execution has begun," said Mark Nall, former director of NASA's Marshall Space Flight Center, now a founding member of the Offsite Space Robotics company. "We have the right words for space exploration: the economic space of the Earth extends across the solar system, it has to work".

Autry agreed with those concerns. "I would like to point out that nobody knows" Who's really on the Business Suite or on the NASA headquarters at NASA, "he said. "I do not see how they are doing when they are running while running."

In some ways, the essential exposure that NASA argues for is a vital step towards human return to the Moon, but others see it as a blend of the lunar people's goal. (The Nation's Space Council User Advisory Group in mid-November, the former Administrator of NASA Mike Griffin said a Gateway was built as "stupid architecture" before humans turned back on the Moon.

"Gateway's goal is, and I do not think that's clearly articulated," said Nulla.

"Personally, I am excited about Gateway, if it is used to display commercial skills on the ground," said Autry. "If this" shop "becomes, to call people as they want, where it becomes a way to get the surface of the moon, then it's impatient."

Johnson argued outsiders to shape the future of space settlement. "Did you know anyone sleeping at a hotel designed by Boeing tonight?" He asked.

But the tendency of the event was that we wanted to face it, on the Moon and Mars, in the Earth's orbit and in more than a thousand people. A good example of this was a panel where Anthony Longman Skyframe Research told a concept that the broad space habitat should have a radius of more than 200 meters and hundreds of houses using hundreds of toning structures using a concept. Participants gave a lot of technical questions about their design, for example, with an estimated 8,000 people or just 1,000.

That is to say, how much you would have cost him how much he asked. "Oh, the costs," he said, and paused, as if to remind him of unpleasant reality. A table, he said, "suggested that it was tens of trillions, but I do not know for sure".

Although too much, we were ready to accept the technical challenges of this structure for the audience. "This is probably not correct," he said, when asked by the public. "The forecast budget was around 400 million. I do not know really."

Initial space settlements should not be large or expensive, but rather perhaps a collection of modules. In a panel, he was asked what MVP is the minimum feasibility product for spatial settlement in the startup world.

"I like cylinders, I like cylinders because they are large and complete," said Al Globus at the University of San Jose State. A modular approach, using a large group of Bigelow Aerospace modules, is possible, but not necessarily desirable. "Modularity needs to be said, building something small and even bigger and up to now. I do not want to live like that. They are too small."

Others, however, thought they were aware of the location of space spaces in space colonies. Karlton Johnson, Arconic Inc. executive and former Air Force officer, just as it was deployed in the field, with little comfort in the home creature. "I suspect, and what I send to you, it will probably be what happens when people spend 90 percent and doing some kind of space operations," he said.

Johnson, a space devoted to space professionals and hardcore space advocates, argued that bringing people outside of the outside space arguing to shape the future of space settlement. "Did you know anyone sleeping at a hotel designed by Boeing tonight?" He asked. "In this room, we want to increase the number of people who have a specific concept of meaning in space, because, first of all, it will be quite strict, but unfortunately we want to be very enjoyable."

Another challenge to space settlement, and another reason to achieve broader public, is more fundamental than a technical problem: why do you live in space? Most of the peers would want to live one day in space, but people would like it, as well as their expectations, living conditions, risks and compensation, as well as an unexplored topic.

"We have to be accountants," said Bolden. "We were not all the story tellers, we would lose."

Globus, which protects the ecosystems below the ecosystem's ecosystem, providing magnetosphere radiation protection, avoiding the loads of part of the Atlantic Ocean Anomaly, is the space settlements of rocky spaces. "A hotel in space is not completely fixed, but most of the problems associated with the construction of the settlement," he said.

But this meeting is a focus on technical issues and politics and, if there is less space for public space, it is not interesting that one of the next steps towards the liquidation of the space is not a new vehicle or habitat, or even a support for the development of public systems public-private Why human beings, and need, are a compelling story that they must live above the Earth.

On the second day of the summit, former NASA Administrator Charlie Bolden attended. (That day, he was a speaker at the summit, although his comments were not a specific question of liquidation space.) He discussed the general debates in the panel discussion about the general public interest.

"We must be accountants, and sometimes, in our technical world, we believe we can do what we can and everything else," he said. "We were not all the story tellers, we would lose."

A sensitive story of space settlement has yet to be told.
