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.

Europe's Sentinel-2a satellite is on course to go into full operation in ahead of schedule or mid-October. The rocket, which takes noticeable and infrared photos of the Earth, was propelled in June and is presently experiencing a time of charging. The eyewitness is the second committed mission to fly in the European Union's Copernicus program. This will see a multi-billion-euro arrangement of satellite sensors put in circle throughout the following couple of years. Sentinel-2a, in any case, will be the framework's spine, delivering an extensive variety of imaging items that will concentrate dominatingly on the planet's property surface. The European Space Agency, which drove the advancement of the stage, discharged a taster on Monday of what's in store. These perspectives went from urban communities and timberlands to ice sheets and coral reefs.Sentinel-2a is what might as well be called America's Landsat mission, which has been imaging the surface of the Earth for a long time.
The US satellite's information is free and open, which has driven a large number of utilization. The vast majority will likely know it best from the guide devices they use on their PCs and cell phones. These all consolidate Landsat pictures. Sentinel's information has been intended to be reciprocal, however the stage additionally speaks to a major hop in capacity. Its imaging instrument will be delicate crosswise over more groups of light (13 versus Landsat's eight), permitting it to recognize more data about the area underneath it; and Sentinel-2a will "cover guide" a much more extensive piece of ground (290 km versus 185 km).
Also, its shading pictures have a best determination of 10 m, versus Landsat's 30 m. Given that today, non-expert utilization of Earth symbolism overwhelmingly depends on Landsat information, it is more than plausible that Sentinel items will be in huge interest. The European Commission will be utilizing Sentinel pictures as a part of its Copernicus project to run mixed bag of administrations, coming to crosswise over farming and ranger service, urban arranging and catastrophe moderation.
Horticulture, however, is sure to be a major client. The satellite's camera sensor has been intended to recognize certain wavelengths of light that detail the strength of plants. In ordinary operation, Sentinel-2a will be creating 1.7 terabytes of handled information every day. Furthermore, this will twofold when the sister satellite, Sentinel-2b, is dispatched one year from now.
"Obviously, we all knew it would be similar to this, however when you stay there with your PC and attempt to download it, it's gigantic - gigabytes of information. I needed to go out at the weekend and purchase a hard circle to store every one of these items for my presentations."
Esa will dispatch Sentinel-3a toward the end of 2015. This satellite is devoted to watching the seas.
