Reaching for the Stars, Across 4.37 Light-Years (New York Times, By DENNIS OVERBYE APRIL 12, 2016) :”Can you fly an iPhone to the stars? In an attempt to leapfrog the planets and vault into the interstellar age, a bevy of scientists and other luminaries from Silicon Valley and beyond, led by Yuri Milner, a Russian philanthropist and Internet entrepreneur, announced a plan on Tuesday to send a fleet of robot spacecraft no bigger than iPhones to Alpha Centauri, the nearest star system, 4.37 light-years away. If it all worked out — a cosmically big “if” that would occur decades and perhaps $10 billion from now — a rocket would deliver a “mother ship” carrying a thousand or so small probes to space. Once in orbit, the probes would unfold thin sails and then, propelled by powerful laser beams from Earth, set off one by one like a flock of migrating butterflies across the universe.”
Yuri Milner, Stephen Hawking’s Breakthrough Starshot targets Alpha Centauri $128M initiative will seek Earth-like planet 40 trillion kilometres away (Thomson Reuters Posted: Apr 12, 2016 1:28 PM ET):”Billionaire internet investor Yuri Milner announced another $128 million ($100 million US) initiative on Tuesday to better understand the cosmos, this time by deploying thousands of tiny spacecraft to travel to our nearest neighboring star system and send back pictures. If successful, scientists could determine if Alpha Centauri, a star system about 40 trillion kilometres (25 trillion miles) away, contains an Earth-like planet capable of sustaining life.”
(LIGO Scientific Collaboration and Virgo Collaboration) Observation of Gravitational Waves from a Binary Black Hole Merger. Phys. Rev. Lett. 116, 061102 – Published 11 February 2016. DOI:http://dx.doi.org/10.1103/PhysRevLett.116.061102)
CONCLUSION
The LIGO detectors have observed gravitational waves from the merger of two stellar-mass black holes. The detected waveform matches the predictions of general relativity for the inspiral and merger of a pair of black holes and the ringdown of the resulting single black hole. These observations demonstrate the existence of binary stellar-mass black hole systems. This is the first direct detection of gravitational waves and the first observation of a binary black hole merger. (DOI:http://dx.doi.org/10.1103/PhysRevLett.116.061102)

Search for Gravitational Waves by LIGO Scientific Collaboration, Particle Physics at the Year of 250th Anniversary of Moscow University (page 152) :””In the last few years a number of long-baseline, laser interferometric gravitational wave detectors have begun operation. These include the Laser Interferometer Gravitational Wave Observatory (LIGO) detectors located in Hanford, Washington and 3000 km away, in Livingston, Louisiana. It is the joint Caltech-MIT project supported by the USA National Science Foundation.””

通常はロケットは打ち上げのときに一度きり使われてきましたが、2015年11月23日に、アマゾンの創業者ジェフ・ベゾスが設立した企業ブルーオリジンが、再利用可能なロケットの着陸に成功しました。これによりロケット打ち上げのコストが劇的に削減される可能性があります。
