From a million miles out in space, NASA’s Earth Polychromatic Imaging Camera (EPIC) captured 12 natural color images of the moon’s shadow crossing over North America on Aug. 21, 2017.
EPIC is aboard NOAA’s Deep Space Climate Observatory (DSCOVR), where it photographs the full sunlit side of Earth every day, giving it a unique view of total solar eclipses.
JunoCam is the “citizen science” camera on board Juno. As the spacecraft orbits Jupiter, JunoCam snaps pictures of the planet from different angles and radial distances, targeting features identified in part through the collaborative efforts of the amateur astronomer community.
SpaceCast Weekly is a NASA Television broadcast from the Johnson Space Center in Houston featuring stories about NASA’s work in human spaceflight, including the International Space Station and its crews and scientific research activities, and the development of Orion and the Space Launch System, the next generation American spacecraft being ...
The sun is the primary source of Earth’s heat, so relatively small changes in solar output can affect our climate. Satellite observations since the late 1970s have shown a slight decrease in the sun’s total energy output. However, instead of cooling, the Earth has warmed over this period. Also, warming ...
Over the last 800,000 years, there have been natural cycles in the Earth’s climate, between ice ages and warmer interglacial periods. After the last ice age 20,000 years ago, average global temperature rose by about 3°C to 8°C, over a period of about 10,000 years.
Hurricanes Laura and Delta dealt a double blow to Louisiana just six weeks apart.
Real-World Testing We loved the last Stumpjumper, but we wanted to make it an even more capable descender—this meant adding stiffness to the frame. To do it, we developed our own mountain-specific stiffness test that examined the connection between a rider’s hands and feet. When each get different signals, you ...
