WASHINGTON (NASA PR) — Earth’s global surface temperatures in 2018 were the fourth warmest since 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA).
Global temperatures in 2018 were 1.5 degrees Fahrenheit (0.83 degrees Celsius) warmer than the 1951 to 1980 mean, according to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. Globally, 2018’s temperatures rank behind those of 2016, 2017 and 2015. The past five years are, collectively, the warmest years in the modern record.

Half a century ago, Apollo 8 ushered in a new era of space exploration. The missions that followed in close succession would herald these breakthroughs in science and in engineering prowess with drama and color. They would bring a cornucopia of knowledge about the Moon, the origins of our solar system, the nature of our universe, the history of our Earth and even the history of life. In addition to tangible, scientific assets gained from Apollo, the mission brought some degree of unification to a nation fractured by conflict at home and abroad.
This week in 1968, the Apollo 8 spacecraft became the first crewed mission to orbit the Moon. Astronauts Frank Borman, Bill Anders and Jim Lovell entered lunar orbit on Dec. 24 and held a live broadcast, showing pictures of Earth and the Moon as seen from the spacecraft and reading from the book of Genesis.
The mission became famous for capturing this iconic “Earthrise” photograph, snapped by Anders as the spacecraft was in the process of rotating. The photo shows Earth rising over the horizon of the Moon and is thought to have sparked the environmental movement. The Apollo 8 mission concluded when the crew splashed down in the Pacific Ocean on Dec. 27.
Now through December 2022, NASA will mark the 50th anniversary of the Apollo Program that landed a dozen astronauts on the Moon between July 1969 and December 1972, and the first U.S. crewed mission — Apollo 8 — that circumnavigated the Moon in December 1968.
The NASA History Program is responsible for generating, disseminating, and preserving NASA’s remarkable history and providing a comprehensive understanding of the institutional, cultural, social, political, economic, technological and scientific aspects of NASA’s activities in aeronautics and space.

Video Caption: In December of 1968, the crew of Apollo 8 became the first people to leave our home planet and travel to another body in space. But as crew members Frank Borman, James Lovell, and William Anders all later recalled, the most important thing they discovered was Earth.
Using photo mosaics and elevation data from Lunar Reconnaissance Orbiter (LRO), this video commemorates Apollo 8’s historic flight by recreating the moment when the crew first saw and photographed the Earth rising from behind the Moon. Narrator Andrew Chaikin, author of “A Man on the Moon,” sets the scene for a three-minute visualization of the view from both inside and outside the spacecraft accompanied by the onboard audio of the astronauts.

“Apollo 8. You are Go for TLI.”
With these cryptic words spoken on Dec. 21, 1968, NASA’s Mission Control gave the crew of Apollo 8 approval for TLI — trans-lunar injection — permission to become the first humans to leave Earth orbit. Their destination, 234,000 miles away, was the Moon.
PASADENA, Calif. (NASA PR) — NASA’s Voyager 1 took a classic portrait of Earth from several billion miles away in 1990. Now a class of tiny, boxy spacecraft, known as CubeSats, have just taken their own version of a “pale blue dot” image, capturing Earth and its moon in one shot.
NASA set a new distance record for CubeSats on May 8 when a pair of CubeSats called Mars Cube One (MarCO) reached 621,371 miles (1 million kilometers) from Earth. One of the CubeSats, called MarCO-B (and affectionately known as “Wall-E” to the MarCO team) used a fisheye camera to snap its first photo on May 9. That photo is part of the process used by the engineering team to confirm the spacecraft’s high-gain antenna has properly unfolded.
Greenbelt, Md. (NASA PR) — As part of an engineering test, NASA’s OSIRIS-REx spacecraft captured this image of the Earth and Moon using its NavCam1 imager on January 17 from a distance of 39.5 million miles (63.6 million km). When the camera acquired the image, the spacecraft was moving away from home at a speed of 19,000 miles per hour (8.5 kilometers per second).
Earth is the largest, brightest spot in the center of the image, with the smaller, dimmer Moon appearing to the right. Several constellations are also visible in the surrounding space. The bright cluster of stars in the upper left corner is the Pleiades in the Taurus constellation. Hamal, the brightest star in Aries, is located in the upper right corner of the image. The Earth-Moon system is centered in the middle of five stars comprising the head of Cetus the Whale.
NavCam1, a grayscale imager, is part of the TAGCAMS (Touch-And-Go Camera System) navigation camera suite. Malin Space Science Systems designed, built, and tested TAGCAMS; Lockheed Martin integrated TAGCAMS to the OSIRIS-REx spacecraft and operates TAGCAMS.
WASHINGTON, DC (NOAA PR) — GOES-16, the first spacecraft in NOAA’s next-generation of geostationary satellites, has sent the first high-resolution images from its Advanced Baseline Imager (ABI) instrument. Included among them are a composite color full-disk visible image of the Western Hemisphere captured on January 15, 2017. Created using several of the ABI’s 16 spectral channels, the full-disk image offers an example the satellite’s advanced technology.
WASHINGTON, DC (NASA PR) — Earth’s 2016 surface temperatures were the warmest since modern recordkeeping began in 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA).
Globally-averaged temperatures in 2016 were 1.78 degrees Fahrenheit (0.99 degrees Celsius) warmer than the mid-20th century mean. This makes 2016 the third year in a row to set a new record for global average surface temperatures.
Video Caption: On July 20, 2015, NASA released to the world the first image of the sunlit side of Earth captured by the space agency’s EPIC camera on NOAA’s DSCOVR satellite. The camera has now recorded a full year of life on Earth from its orbit at Lagrange point 1, approximately 1 million miles from Earth, where it is balanced between the gravity of our home planet and the sun.
EPIC takes a new picture every two hours, revealing how the planet would look to human eyes, capturing the ever-changing motion of clouds and weather systems and the fixed features of Earth such as deserts, forests and the distinct blues of different seas. EPIC will allow scientists to monitor ozone and aerosol levels in Earth’s atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of Earth.
The primary objective of DSCOVR, a partnership between NASA, the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Air Force, is to maintain the nation’s real-time solar wind monitoring capabilities, which are critical to the accuracy and lead time of space weather alerts and forecasts from NOAA.

GREENBELT, Md. (NASA PR) — NASA launched a new website Monday so the world can see images of the full, sunlit side of the Earth every day. 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 U.S. Air Force.
