Watch Earth as it rotates on new NASA website

Washington: NASA has launched a new website where you can see images of the full, sunlit side of the Earth as it rotates every day.

Once a day, the US space agency will post at least a dozen new colour images of Earth acquired from 12 to 36 hours earlier by NASA’s Earth Polychromatic Imaging Camera (EPIC).

Each daily sequence of images will show the Earth as it rotates, thus revealing the whole globe over the course of a day.

The new website also features an archive of EPIC images that can be searched by date and continent.

The images are taken by a NASA camera one million miles away on the Deep Space Climate Observatory (DSCOVR), a partnership between NASA, the National Oceanic and Atmospheric Administration (NOAA) and the US Air Force, said a NASA statement.

EPIC is a four megapixel CCD camera and telescope. The camera takes a series of 10 images to produce a variety of science products.

“The effective resolution of the EPIC camera is somewhere between 10-15 km,” said Adam Szabo, DSCOVR project scientist at NASA’s Goddard Space Flight Centre in Maryland.

Since Earth is extremely bright in the darkness of space, EPIC has to take very short exposure images (20-100 milliseconds).

The much fainter stars are not visible in the background as a result of the short exposure times.

The url of the new website is http://epic.gsfc.nasa.gov.

A U.S. astronaut said on Thursday she had full confidence in the safety of the Russian-made Soyuz rocket that will blast a three-person crew into space next month in the first such launch since a rocket failure.

Russian cosmonaut Oleg Kononenko and U.S. and Canadian astronauts Anne McClain and David Saint-Jacques are due to embark for the International Space Station on Dec. 3 after a similar launch on Oct. 11 ended in an emergency landing.

Two minutes into that launch, a rocket failure forced Russian cosmonaut Alexei Ovchinin and U.S. astronaut Nick Hague to abort their mission and hurtle back to Earth in a capsule that landed in the Kazakh steppe. The two were unharmed.

Speaking at a news conference in Star City near Moscow, McClain said that occasional failures were inevitable, but that the mishap with the Soyuz-FG in October had demonstrated the reliability of its emergency safety mechanisms.

“We trust our rocket. We’re ready to fly,” she said at the conference also attended by her colleagues Kononenko and Saint-Jacques.

“A lot of people called it an accident, or an incident, or maybe want to use it as an example of it not being safe, but for us it’s exactly the opposite because our friends came home,” McClain told reporters.

Russian investigators said the rocket failure was caused by a sensor that was damaged during assembly at the Soviet era-cosmodrome at Baikonur from where McClain, Saint Jacques and Kononenko are due to launch.

Ahead of their mission, an unmanned rocket carrying cargo is due to launch on Nov 16. in what will be the first Soyuz-FG take-off from Baikonur since the mishap. (VOA)
