"Plans for Earth's first starships are being announced today in New York City. At a midday press conference, Yuri Milner's Breakthrough Prize Foundation is unveiling its latest project: "Breakthrough Starshot". If Milner's team can pull this off, people alive today could see starships depart from our planet and reach another star system within their lifetime. And everyone will be invited to help make that happen. The plan is simple: create an immensely powerful, system of ground-based lasers and use them to propel tiny starships up to 20% of the speed of light. The starships' first target would be the Alpha Centauri star system 4.3 light years away. These starships would arrive just 20 years after leaving Earth."
"Breakthrough Starshot is a $100 million research and engineering program aiming to demonstrate proof of concept for light-propelled nanocrafts. These could fly at 20 percent of light speed and capture images of possible planets and other scientific data in our nearest star system, Alpha Centauri, just over 20 years after their launch. The program will be led by Pete Worden, the former director of NASA AMES Research Center, and advised by a committee of world-class scientists and engineers. The board will consist of Stephen Hawking, Yuri Milner, and Mark Zuckerberg."
Keith's note: I asked NASA for a comment on the Breakthrough Starshot announcement. They replied: "In 2015, the NIAC program selected University of California, Santa Barbara Professor Philip Lubin's study on directed energy propulsion for exploring other worlds. NASA is pleased to hear that Professor Lubin has received external funding to continue the work started in his NIAC study. When the study's final report has been cleared for 508 compliance, it will be posted online here. The NASA Innovative Advanced Concepts (NIAC) program focuses research on futuristic but technically credible concepts that could one day "change the possible" in aerospace." I have asked for a copy of this report - I do not need a 508 compliant version. This is a hot topic right now. Talk about a cosmic spinoff.
