Solar plane lands in New York City

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...

An American satellite obtained a unique view of a lunar eclipse

The DSCOVR spacecraft, which was launched in February, has a camera that stares constantly at the sunlit face of the Earth.  The images are being used to track moving features such as clouds and dust storms, and to monitor the climate.  But on 27 September, it was in just the right position to see the Moon go behind the Earth and into its shadow.  On the ground at this time, skywatchers would have observed the lunar body turn a shade of red.  It does this because some sunlight is still able to reach the Moon's surface after being filtered through the Earth's atmosphere.  "Our camera is normally centred on the Earth but we use the Moon for calibration," explained Jay Herman, the US space agency's (Nasa) lead investigator onDSCOVR's Epic camera system.  "That's what we were doing on this occasion. We were staring at the Moon and the Earth moved in front about four hours before the eclipse was seen on Earth. And that's because we were at an an...

Scientists are getting closer to explaining precisely how Mars lost its atmosphere

Researchers working on the US space agency's Maven satellite have reported their first big set of results in a clutch of scholarly papers.  These detail how Martian air today is being removed at high altitudes through its interactions with the Sun.  They calculate the rates at which gases escape, and suggest why these rates may have been even higher in the past.  "We're well on the way to answering many of our questions; much further along actually than I thought we would be at this stage," said Bruce Jakosky, the principal investigator on Nasa's Maven spacecraft.  "What we're reporting today is data from just the first 6-7 months from our primary mission.All the observations by previous satellites and landers at the Red Planet indicate that it was once shrouded in a thick blanket of gases, which supported the presence of liquid water at its surface. This is evident in the many landscape features that resemble the  remains of river channels, de...

Facebook is to launch a satellite in 2016, Mark Zuckerberg has announced

Facebook is to launch a satellite in 2016 In partnership with French-based provider Eutelsat, Facebook hope the first satellite will be launched in 2016.  "We're going to keep working to connect the entire world -- even if that means looking beyond our planet," Mark Zuckerberg said in a Facebook post.  The project is part of Facebook's Internet.org project, which has come under fierce criticism in some countries.  In some areas, particularly India, businesses reacted angrily to the plans saying it gave Facebook, and its partners, an unfair advantage in developing internet markets.  Internet.org is experimenting with different ways of providing internet to hard-to-reach places. Recently, the company told of how it was planning to use a custom-built drone to beam down connectivity.
