NEW YORK (NASA PR) — Earth’s global average surface temperature in 2020 tied with 2016 as the warmest year on record, according to an analysis by NASA.
Continuing the planet’s long-term warming trend, the year’s globally averaged temperature was 1.84 degrees Fahrenheit (1.02 degrees Celsius) warmer than the baseline 1951-1980 mean, according to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. 2020 edged out 2016 by a very small amount, within the margin of error of the analysis, making the years effectively tied for the warmest year on record.
ASHINGTON (NASA PR) — NASA has approved two heliophysics missions to explore the Sun and the system that drives space weather near Earth. Together, NASA’s contribution to the Extreme Ultraviolet High-Throughput Spectroscopic Telescope Epsilon Mission, or EUVST, and the Electrojet Zeeman Imaging Explorer, or EZIE, will help us understand the Sun and Earth as an interconnected system.
$30K in Prizes for Improvements of Current Models to Provide Advance Warning of Geomagnetic Storms and Reduce Errors in Navigation Systems
Boulder, Colorado — December 15, 2020 —The National Oceanic and Atmospheric Administration (NOAA) in partnership with the NASA Tournament Lab today announced its crowdsourcing challenge, “MagNet: Model the Geomagnetic Field”. The challenge, which is being implemented by DrivenData and HeroX, seeks to mitigate the impact of geomagnetic storms on navigation systems through improved forecasting by increasing the accuracy in real-time magnetic field modeling and reducing errors in the magnetic navigation systems.

GREENBELT, Md. — At the edge of space, the ever-growing fleet of satellites in low-Earth orbit are locked in a constant, precarious battle with friction.
These satellites orbit in a normally quiet region hundreds of miles above the surface, at the edge of Earth’s atmosphere. Usually, the satellites only feel a gentle push due to the headwinds of the rarified air there, but extreme storms from the Sun can change Earth’s atmosphere enough to pull a satellite farther off orbit in one day than they’d normally experience in a year.
OSTP Showcases S&T Wins That Changed the World Over the Past Four Years
WASHINGTON (OSTP PR) — The White House Office of Science and Technology Policy (OSTP) today released “Advancing America’s Global Leadership in Science and Technology, Trump Administration Highlights: 2017-2020.” The document is a selection of significant investments, accomplishments, policies, and other actions undertaken by President Trump to advance science and technology.
KENNEDY SPACE CENTER, Fla. (NASA PR) — NASA has selected Space Exploration Technologies (SpaceX) of Hawthorne, California, to provide launch services for the agency’s Interstellar Mapping and Acceleration Probe (IMAP) mission, which includes four secondary payloads.
IMAP will help researchers better understand the boundary of the heliosphere, a magnetic barrier surrounding our solar system. This region is where the constant flow of particles from our Sun, called the solar wind, collides with winds from other stars. This collision limits the amount of harmful cosmic radiation entering the heliosphere.
PARIS (ESA PR) — ESA’s ExoMars Trace Gas Orbiter has spotted new gas signatures at Mars. These unlock new secrets about the martian atmosphere, and will enable a more accurate determination of whether there is methane, a gas associated with biological or geological activity, at the planet.
The Trace Gas Orbiter (TGO) has been studying the Red Planet from orbit for over two years. The mission aims to understand the mixture of gases that make up the martian atmosphere, with a special focus on the mystery surrounding the presence of methane there.
TOKYO (Earth-Life Science Institute PR) — Earth’s Moon has a ‘near side’ that is perpetually Earth-facing and a ‘far side’, which always faces away from Earth. The composition of the Moon’s near side is oddly different from its far side, and scientists think they finally understand why.
The Earth-Moon system’s history remains mysterious. Scientists believe the two formed when a Mars-sized body collided with the proto-Earth. Earth ended up being the larger daughter of this collision and retained enough heat to become tectonically active. The Moon, being smaller, likely cooled down faster and geologically ‘froze’. The apparent early dynamism of the Moon challenges this idea.
The contrast was jarring. In one browser window, two NASA astronauts were making their way to the International Space Station (ISS) after the first orbital launch of a crew from U.S. soil in nearly 9 years.
In another window, scenes of chaos played out as protests over the death of George Floyd after his arrest by Minneapolis police erupted into violent clashes across the country.
New Horizons Mission Update by Alan Stern Principal Investigator
New Horizons is healthy and performing perfectly as it flies deeper and deeper into the Kuiper Belt! Recently we conducted an engineering review of the spacecraft to “trend” how it was working compared to when it was launched. The result was amazing: Every system and science instrument aboard New Horizons is working as well as it did when we lifted off, more than 14 years and almost 5 billion miles ago. As mission principal investigator I could not be prouder — the men and women who designed, built and tested New Horizons literally created a masterpiece of American workmanship that will likely be able to perform and explore for many more years and many more miles!
WASHINGTON (NASA PR) — In 1970, the United States Clean Air Act underwent major revisions to reduce pollution and protect air quality, President Nixon created the Environmental Protection Agency, and NASA scientists were cracking open the door on a new era of studying our home planet from space.
The first black-and-white satellite images of Earth were just ten years old: a swirling mass of white clouds over back oceans. The first measurements of Earth’s temperature from space were made just a year prior in 1969 by Nimbus 3, a joint mission with the National Oceanic and Atmospheric Administration, which became a major step in improving weather forecasts.
MOUNTAIN VIEW, Calif. (SETI Institute PR) — In a new paper published in the Astrophysical Journal Letters, co-authored by SETI Institute scientist Jeff Coughlin, astronomers using Kepler data have identified a planet nearly the same size of Earth that orbits in its star’s habitable zone, where liquid water could exist on its surface.
This new world, Kepler-1649c, is 300 light-years away and orbits a star that is about one-fourth the size of our Sun. Only 6% bigger than the Earth, it shares its sun with a planet much like Venus, Kepler-1649b, which was discovered three years ago. Although NASA’s Kepler space telescope was retired in 2018 when it ran out of fuel, scientists are still making discoveries as they continue to examine the signals Kepler detected.
PARIS (ESA PR) — The ESA/JAXA BepiColombo mission completed its first flyby on 10 April, as the spacecraft came less than 12 700 km from Earth’s surface at 06:25 CEST, steering its trajectory towards the final destination, Mercury. Images gathered just before closest approach portray our planet shining through darkness, during one of humankind’s most challenging times in recent history.
