If we are ever going to be go beyond the solar system, to share the miracle of Earth Life, it\u2019s clear that we will need radical new ways of getting there.<\/p>\n

\n

One such solution that was recently proposed uses electron beams accelerated to near the speed of light to propel spacecraft, something that could overcome the vast distances between Earth and the next closest star. \u201cFor interstellar flight, the primary challenge is that the distances are so great,\u201d Greason explained. \u201cAlpha Centauri<\/a> is 4.3 light-years away; about 2,000 times further away from the sun<\/a> than the Voyager 1 spacecraft<\/a> has reached \u2014 the furthest spacecraft we\u2019ve ever sent into deep space so far. No one is likely to fund a scientific mission that takes much longer than 30 years to return the data \u2014 that means we need to fly fast.\u201d<\/p>\n

A study by Greason and Gerrit Bruhaug, a physicist at Los Alamos National Laboratory, published in the journal Acta Astronautica<\/a>, highlights that reaching practical interstellar speeds hinges on the ability to deliver sufficient amounts of kinetic energy to the spacecraft in an economic way.<\/p>\n

\u201cInterstellar flight requires us to collect and control vast amounts of energy to achieve speeds fast enough to be useful,\u201d said Greason. \u201cChemical rockets that we use today, even with the extra speed boost from flying by planets, or from [\u2026] swinging by the sun for a boost, just don\u2019t have the ability to scale to useful interstellar speeds.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
