【未来太空家园:NASA计划开发深空栖息地】NASA计划于2030年左右将人类送上火星,但其现在就需要设计火星人类栖息地,以便帮助经过漫长旅途到达火星的人类存活下来。美国宇航局已经向6家公司提供资金,支持它们在2年内开发和测试可供深空(包括火星表面)使用的人类栖息地。若栖息地建成,可帮助人们探索太空中更远的地方。

Space homes of the future: Nasa unveils designs for habitats that could be used in long-haul missions

  • The space agency will work with it partners to develop habitats for extended manned missions in space
  • Full-sized prototypes will be built on Earth to test how systems interact and gather critical safety data
  • Initially, the habitats will be designed for extended missions near the moon before moving further afield
  • Aerospace firms involved in satellite technology and ISS resupply missions have been signed up

With exploratory probes scouting out Earth’s neighbouring planets and moons, space agencies are working to develop the next generation of habitats to get crews there and far beyond.

This week Nasa named its six partners for developing crafts to house a human crew in deep space.

Concept habitats will be built here on Earth, to help the space agency gain a better insight into the needs and opportunities for extensive manned missions around the moon and beyond.

Nasa has released artists' impressions from its six contenders, which come from well-established aerospace firms already working with space agencies on satellite and probe technology.

Included in the mix is Bigelow Aerospace, the Nevada-based firm behind the inflatable pod recently installed on the International Space Station, as well as long standing partners Boeing and Lockheed Martin.

The partnerships are part of Nasa's 'NextSTEP' programme, which will see a mix of private and public expertise and resources combined to push the existing boundaries of manned space exploration, initially testing a manned habitat near the moon as a testing ground for Mars and beyond.

‘The NextSTEP partnerships are a large contribution to the dual objectives of advancing deep space habitation development and stimulating commercial activities in low-Earth orbit,’ said Jason Crusan, Nasa’s director of Advanced Exploration Systems.

Earlier this year, Crusan highlighted the importance of collaboration in pushing the boundaries of space exploration.

He said: 'Nasa is increasingly embracing public-private partnerships to expand capabilities, and opportunities in space.'

All of the habitat designs incorporate the same core components, including a pressurised space for the crew to live, along with environmental control and life support systems.

They will also include propulsion technology, docking capability as well as sufficient radiation shielding, to protect the crew inside from the harsh environment of space.

Building prototypes on the ground will enable extensive testing and provide Nasa and its partners crucial data on how the various systems interact.

Boeing will develop a modular habitat based on the firm’s experience gathered from working on the ISS for more than 15 years.

The full-scale prototype will be built on the ground to test the systems and the suitability as a habitat for astronauts for extended periods.

A second approach will see Lockheed Martin refurbish a multi-purpose logistics module, similar to the ones which carry cargo to the space station, while Orbital ATK will continue development of a habitat based on its unmanned Cygnus spacecraft, which has also made successful delivery runs to the ISS.

One of the partners is basing its prototype of a low-Earth orbit plane to transport up to seven passengers.

Sierra Nevada Corporation plans to use its Dream Chaser spacecraft along with an inflatable module, testing all systems together.

The inflatable approach is already being tested in space, with Bigelow’s expandable BEAM habitat installed aboard the space station.

The firm aims to expand on this success further with an even larger 330 cubic metre pod called the XBase.

The final partner is the Ixion Team, a conglomerate of three small aerospace space firms which will look at converting a rocket’s launch stage into a pressurised habitat.
