U.S. Postal Service to Issue NASA Sun Science Forever Stamps

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s images of the Sun’s dynamic and ­­­dazzling beauty have captivated the attention of millions. In 2021, the U.S. Postal Service is showcasing the Sun’s many faces with a series of Sun Science forever stamps that show images of solar activity captured by NASA’s Solar Dynamics Observatory, or SDO.

“I have been a stamp collector all my life and I can’t wait to see NASA science highlighted in this way,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate (SMD) in Washington.

NASA has Two Heliophysics Missions that will Explore Sun, Earth’s Aurora

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – 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.

Understanding the physics that drive the solar wind and solar explosions – including solar flares and coronal mass ejections – could one day help scientists predict these events, which can impact human technology and explorers in space.

NASA’s Dione CubeSat mission to study Earth’s Upper Atmosphere, Space Weather

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA has selected a new pathfinding CubeSat mission to gather data not collected since the agency flew the Dynamics Explorer in the early 1980s.

The new mission, called Dione after the ancient Greek goddess of the oracles, will carry four miniaturized instruments to study how Earth’s upper atmospheric layers react to the ever-changing flow of solar energy into the magnetosphere — the enveloping bubble of magnetic field around Earth that deflects most of the particles that erupt from the Sun. Earth’s upper atmosphere is where most low-Earth-orbiting satellites reside, and their orbits are strongly affected by sudden density changes created by space weather.

Dione will gather data not collected since NASA’s dual-spacecraft Dynamics Explorer mission launched in the early 1980s. (NASA)

NASA SunRISE mission to use Six Spacecraft to study Giant Solar Particle Storms

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA has selected a new mission to study how the Sun generates and releases giant space weather storms – known as solar particle storms – into planetary space.

Not only will such information improve understanding of how our solar system works, but it ultimately can help protect astronauts traveling to the Moon and Mars by providing better information on how the Sun’s radiation affects the space environment they must travel through.

A new NASA mission called SunRISE will study what drives solar particle storms - giant surges of solar particles that erupt off of the Sun - as depicted in this illustration. Understanding how such storms affect interplanetary space can help protect spacecraft and astronauts. (NASA)

NASA’s Solar Dynamics Observatory has shown us 10 Things about the Sun

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – In February 2020, NASA’s Solar Dynamics Observatory — SDO — is celebrating its 10th year in space. Over the past decade the spacecraft has kept a constant eye on the Sun, studying how the Sun creates solar activity and drives space weather — the dynamic conditions in space that impact the entire solar system, including Earth.

Since its launch on February 11th, 2010, SDO has collected millions of scientific images of our nearest star, giving scientists new insights into its workings.

NASA’s Parker Solar Probe discovers new insights about our Sun

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – In August 2018, NASA’s Parker Solar Probe launched to space, soon becoming the closest-ever spacecraft to the Sun. With cutting-edge scientific instruments to measure the environment around the spacecraft, Parker Solar Probe has completed three of 24 planned passes through never-before-explored parts of the Sun’s atmosphere, the corona.

On December 4th, 2019, four new papers in the journal Nature describe what scientists have learned from this unprecedented exploration of our star — and what they look forward to learning next.

NASA launches Ionospheric Connection Explorer (ICON) spacecraft

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – After a successful Thursday night, October 10th, 2019 launch, NASA’s Ionospheric Connection Explorer (ICON) spacecraft is in orbit for a first-of-its-kind mission to study a region of space where changes can disrupt communications and satellite orbits, and even increase radiation risks to astronauts.

A Northrop Grumman Stargazer L-1011 aircraft took off at 7:31pm CDT from Cape Canaveral Air Force Station in Florida carrying ICON, on a Northrop Grumman Pegasus XL rocket, to launch altitude of about 39,000 feet.

Northrop Grumman’s L-1011 aircraft, Stargazer, prepares for takeoff at the Cape Canaveral Air Force Station Skid Strip in Florida on Oct. 10, 2019. Attached beneath the aircraft is the company’s Pegasus XL rocket, carrying NASA’s Ionospheric Connection Explorer (ICON). (NASA)

NASA’s twin E-TBEx CubeSats to study how signals get disrupted in Earth’s Ionosphere

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – In June 2019, the NASA twin E-TBEx CubeSats — short for Enhanced Tandem Beacon Experiment — are scheduled to launch aboard the Department of Defense’s Space Test Program-2 launch.

The launch includes a total of 24 satellites from government and research institutions.

They will launch aboard a SpaceX Falcon Heavy from historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

NASA to Study Space Weather around Earth from International Space Station

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA has selected a new mission that will help scientists understand and, ultimately, forecast the vast space weather system around our planet. Space weather is important  because it can have profound impacts – affecting technology and astronauts in space, disrupting radio communications and, at its most severe, overwhelming power grids.

The new experiment will, for the first time, obtain global observations of an important driver of space weather in a dynamic region of Earth’s upper atmosphere that can cause interference with radio and GPS communications.

An image taken from the International Space Station shows orange swaths of airglow hovering in Earth’s atmosphere. NASA’s new Atmospheric Waves Experiment will observe this airglow from a perch on the space station to help scientists understand, and ultimately improve forecasts of, space weather changes in the upper atmosphere.

NASA’s Parker Solar Probe launches tonight

 

Written by Miles Hatfield
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – At 2:33am CDT on August 11th, 2018 while most of the U.S. is asleep, NASA’s Kennedy Space Center in Florida will be abuzz with excitement. At that moment, NASA’s Parker Solar Probe, the agency’s historic mission to touch the Sun, will have its first opportunity to lift off.

Launching from Cape Canaveral Air Force Station in Florida, Parker Solar Probe will make its journey all the way to the Sun’s atmosphere, or corona — closer to the Sun than any spacecraft in history.

“Eight long years of hard work by countless engineers and scientists is finally paying off,” said Adam Szabo, the mission scientist for Parker Solar Probe at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
