It\u2019s going to happen a little bit more slowly.\u201d<\/p>\n<p>The mission is designed to garner new information about the potential to harvest resources from asteroids, as well as the origin of life as we know it.<\/p>\n<p>\u201cThis exploration incorporates both the science, exploration, resource utilisation and planetary defence all in one go,\u201d Dr Abell told news.com.au.<\/p>\n<p>\u201cWe can do things that will further humanity\u2019s forays into space \u2014 going to Mars and expanding the human presence in the solar system.<\/p>\n<p>\u201cWe also expand our scientific horizons in learning about what\u2019s out there in the solar system.<\/p>\n<p>\u201cAnd also being able to live off the land \u2013 resource utilisation is going to be key.&#8221;<\/p>\n<p>Oh, and did we mention planetary defence?<\/p>\n<p>\u201cVery important to the general public is the aspect of planetary defence and making sure we don\u2019t have an impact and making sure our grand-children or great grand-children don\u2019t have to worry about an asteroid coming in and hitting the planet,&#8221; Dr Abell said.<\/p>\n<p>NASA won\u2019t be able to land a spacecraft on the asteroid directly however, as most asteroids have a very weak gravitational field.<\/p>\n<p>That makes things a little tricky, because asteroids travel at speeds ranging from 54,000 to 90,000km\/h.<\/p>\n<p>The spacecraft is going to have to travel at the exact same speed as the asteroid while the astronauts deploy to and from it to collect samples and conduct experiments.<\/p>\n<p>&#8220;One of the things we are looking at in earnest is seeing if we can anchor or attach or tether equipment and astronauts to the surface,&#8221; Dr Abell said.<\/p>\n<p>Though they\u2019ve had plenty of volunteers, NASA is yet to pick a team of astronauts and do not plan on doing so for at least another five years.<\/p>\n<p>But if you&#8217;re thinking of applying for the job, know this \u2014 you have to be an experienced spacewalker.<\/p>\n<p>&#8220;It takes a tremendous amount of strength upper body strength and endurance. It&#8217;s very, very tiring,&#8221; Dr Abell said.<\/p>\n<p>&#8220;You\u2019re probably going to have to be doing EVAs (extra vehicle activities) on the order of maybe 8 to 12 hours at a time on these missions, so the astronauts really have to be fit both physically and mentally for what they are going to be doing.&#8221;<\/p>\n<p>In fact the physical activity is so strenuous that NASA is considering recruiting a new generation of younger astronauts for the job \u2014 blowing yet another hole in the plot of Armageddon.<\/p>\n<p>Bruce Willis and his team would simply have been too old.<\/p>\n<p>&#8220;The astronauts we send on this mission may not even be the ones we have in our current core,&#8221; Dr Abell said.<\/p>\n<p>&#8220;They may be people who are in university right now or in high school right now. We\u2019ll see.&#8221;<\/p>\n<p>NASA hasn&#8217;t yet chosen an asteroid on which to land yet either, but they have it narrowed down to a group of 1200 \u201cpotentially hazardous\u201d asteroids that present a potential risk to Earth and its inhabitants.<\/p>\n<p>&#8220;If an object is potentially hazardous, it&#8217;s because it makes close approaches to the Earth,&#8221; Dr Abell said.<\/p>\n<p>&#8220;So the objects that are potentially hazardous, even though they\u2019re present a hazard, they also present the best opportunity for us to go out and get them and learn about them.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ASTRONAUTS are lining up to be candidates for an extreme trip of a lifetime.
