The 1990s era hardware wasn’t up to the task of gathering the data scientists want, but the agency deployed the first of its new generation GOES-R satellites in 2016. Earlier this year, a second GOES satellite went into orbit. It has just sent back its first stunning images of Earth, but there are some glitches that keep the system for working at full capacity.
The Global Positioning System (GPS) is a collection of satellites, each containing a powerful and precise atomic clock, that broadcasts their time every 30 seconds. Handheld receivers, like your smartphone, can collect this data and perform calculations to figure out their position on the surface of the Earth.
The massive asteroid that is thought to have wiped out the dinosaurs was one of the most significant events in Earth's history, and without it there's a really good chance humans might never have existed at all. With that in mind, it's hard to imagine how the space rock's impact could have been even more devastating than scientists have assumed, but new research suggests exactly that, and paints an even more dire picture of what life was like on Earth in the years that followed.
An international scientific team recently published a new map of the ocean floor based on Earth’s gravity field, and it is a particularly useful tool. Such seafloor maps can aid submariners and ship captains with navigation, particularly in previously uncharted areas. They are helpful to prospectors scouting for oil, gas, and mineral resources. And the maps comprise nearly 80 percent of the seafloor that you see when you scroll through Google Earth.
NASA's Lunar Reconnaissance Orbiter (LRO) recently captured a unique view of Earth from the spacecraft's vantage point in orbit around the moon.
A NASA camera on the Deep Space Climate Observatory (DSCOVR) satellite has captured a series of stunning images of the Moon passing the Earth’s sunlit side. The images were captured last month by NASA’s Earth Polychromatic Imaging Camera (EPIC), a four megapixel camera and telescope.
An international Earth-observing mission launched in 2011 to study the salinity of the ocean surface ended June 8 when an essential part of the power and attitude control system for the SAC-D spacecraft, stopped operating.
