The objectives are to design a fly-by mission to Alpha Centauri with a total mission duration of 50 years travelling at a cruise speed of 0.1c. Furthermore, optical data from the target star system is to be obtained and sent back to the Solar system. The main challenges of such a mission are presented and possible solutions proposed. The results show that by extrapolating from currently existing technology, such a mission would be feasible. The total mass of the proposed spacecraft is 23g and the space-based laser infrastructure has a beam power output of 15GW. Rurther exploration of the laser \u2014 spacecraft tradespace and associated technologies are necessary.\u201d<\/p>\n<p><a href=\"https:\/\/l.facebook.com\/l.php?u=https%3A%2F%2Farxiv.org%2Fabs%2F1708.03556&h=ATMBJT6ghs5WmwKIsv_Ii2Xc2LVI32rHOaz0-gPCT2LMzFEHtG8wQ1Zcm9AmQcn4AJGlmR4JYrp5c9UATgf9bD30yQs5847uxQT6_pqKhqKjdor2j_xEs25ya71abztSKLMLNthDYT3r91W0Ly8b_54p71YbADz3Dy8TtQ&enc=AZOqLZTWo1MmW07RsXntHJ5p7kbHAwOWaUZdBcUAJJkaESjzMse4tXj0YDAQ03pvRD-tvuP6bQ2iMummIy5tcq7zNM9HKLO6gN71dYBbpwfAuPFKGfg5s5dfvmebFxCI1Qi1aZPvXDpZumpxfRNegUe7hfIy5uTH7iG2hduFlpa6QWTv3uIdSJwBXR0ZKuZjPWk_mkMCJrcMREhoqRJFOqZO&s=1\" target=\"_blank\" data-ft=\"{\u201ctn\u201d:\u201d-U\u201d}\" rel=\"nofollow\"><a href=\"https:\/\/arxiv.org\/abs\/1708.03556\">https:\/\/arxiv.org\/abs\/1708.03556<\/a><\/a><\/p>\n<p><!-- Link: <a href=\"https:\/\/www.facebook.com\/InterstellarInstitute\/photos\/a.144466059032050.48811.142990469179609\/1221385778006734\/?type=3\">https:\/\/www.facebook.com\/InterstellarInstitute\/photos\/a.1444...34\/?type=3<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u201cThis paper discusses the physics, engineering and mission architecture relating to a gram-sized interstellar probe propelled by a laser beam.
