Reviewed.com: NASA’s panoramic photo of Earth is epic
NASA’s Landsat mission has been utilizing satellites to capture images of the planet for more than 40 years, but their gear has been in sore need of an upgrade. To remedy the situation, NASA recently kicked off the Landsat Data Continuity Mission (LDCM), putting a new satellite in space on February 11th.
After calibrating the new imager over the last couple months, NASA marked the satellite’s ascent to its target altitude with some promotional imagery. NASA used the satellite’s Operational Land Imager (OLI)—the special camera designed to capture high-resolution shots of the planet across the light spectrum—to record a 6,000-mile-long panorama of a 120-mile-wide sliver of Earth, an expanse stretching from Russia, to Saudi Arabia, to South Africa.
The panorama is stitched together from 56 individual scenes taken with the new OLI. The camera’s pushbroom sensor moves across the scene much the way that a document scanner would, except this particular

This diagram lines up planets recently discovered by Kepler in terms of their sizes, compared to Earth. Kepler-22b was announced in December 2011; the three Super-Earths were announced April 18, 2013. All of them could potentially host life, but we do not yet know anything definitive about their compositions or atmosphere.

Spacewalkers tackle leak at space station
CAPE CANAVERAL, Fla. — Two NASA spacewalkers stepped outside the International Space Station on Saturday to fix a serious coolant leak.
American astronauts Chris Cassidy and Tom Marshburn didn’t see any sign of the leak by the time they reached the end of the station’s central truss. But they quickly replaced a box that controls the flow of ammonia coolant in that area, which engineers suspected had failed and sprung the leak.
When ground controllers powered up the replacement box, the spacewalkers reported seeing no white flakes of ammonia crystals that would indicate an ongoing leak.
“No snow,” Cassidy radioed.
The astronauts returned safely to the space station after 5 1/2 hours outside.
NASA says it may take
