A solar-powered airplane finished crossing the United States on Saturday, landing in New York City after flying over the Statue of Liberty during its historic bid to circle the globe, the project team said. The spindly, single-seat experimental aircraft, dubbed Solar Impulse 2, arrived at New York's John F. Kennedy International Airport at about 4 a.m. local time after it took off about five hours beforehand at Lehigh Valley International Airport in Pennsylvania, the team reported on the airplane's website. Such a pleasure to land in New York! For the 14th time we celebrate sustainability," said the project's co-founder Andre Borschberg on Twitter after flying over the city and the Statue of Liberty during the 14th leg of the trip around the globe. The Swiss team flying the aircraft in a campaign to build support for clean energy technologies hopes eventually to complete its circumnavigation in Abu Dhabi, where the journey began in March 2015. The solar cr...
Appearing in Science magazine, the article is largely a collation of information already made public through media briefings and press releases. It includes the mission team’s initial impressions of Pluto and its moons: Charon, Styx, Nix, Kerberos and Hydra. And, of course, it details some of the basic numbers that can now be used to describe these far-flung objects. Every week, we have something new and wonderful to look at and speculate aboutDr John Spencer, Southwest Research Institute. One key early result from the US space agency (Nasa) probe is the precise measure of Pluto's radius, of 1,187km, plus or minus 4km. "This doesn't sound particularly exciting but you have to remember estimates of Pluto's radius varied from 1,150km to 1,200km, so this will really help those people modelling how Pluto/Charon formed, their atmospheres and the material exchange between them," said team member Dr Carly Howett from the Southwest Research Institute (SwRI) ...
