Earth is immersed in material streaming from the Sun. This stream, called the solar wind, is washing over our planet, causing breathtaking auroras, impacting satellites and astronauts in space, and even affecting ground-based infrastructure. NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission will be the first to image the Sun’s corona, or outer … Read more
NASA will hold a media teleconference at 2 p.m. EST on Tuesday, Feb. 4, to share information about the agency’s upcoming PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission, which is targeted to launch no earlier than Thursday, Feb. 27. The agency’s PUNCH mission is a constellation of four small satellites. When they arrive … Read more
Technicians supporting NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission deployed and tested the spacecraft’s solar arrays at the Astrotech Space Operations processing facility at Vandenberg Space Force Base in California ahead of its launch next month. The arrays, essential for powering instruments and systems, mark another milestone in preparing PUNCH for its … Read more
NASA’s Parker Solar Probe survived its record-breaking closest approach to the solar surface on Dec. 24, 2024. Breaking its previous record by flying just 3.8 million miles above the surface of the Sun, the spacecraft hurtled through the solar atmosphere at a blazing 430,000 miles per hour — faster than any human-made object has ever … Read more
NASA’s Voyager 2 flyby of Uranus decades ago shaped scientists’ understanding of the planet but also introduced unexplained oddities. A recent data dive has offered answers. When NASA’s Voyager 2 spacecraft flew by Uranus in 1986, it provided scientists’ first — and, so far, only — close glimpse of this strange, sideways-rotating outer planet. Alongside … Read more
The closest approach to the Sun, or perihelion, will occur on Dec. 24, 2024, during which mission control will be out of contact with the spacecraft. Parker will send a beacon tone on Dec. 27, 2024, to confirm its success and the spacecraft’s health. Parker will remain in this orbit for the remainder of its … Read more
According to Lynn Wilson, who is the Wind project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, fuel is only one indicator of Wind’s life expectancy, however. “Based on fuel alone, Wind can continue flying until 2074,” he said. “On the other hand, its ability to return data hinges on the last surviving … Read more
4 min read NASA Technologies Named Among TIME Inventions of 2024 As NASA continues to innovate for the benefit of humanity, agency inventions that use new structures to harness sunlight for space travel, enable communications with spacecraft at record-breaking distances, and determine the habitability of a moon of Jupiter, were named Wednesday among TIME’s Inventions … Read more
“Our study addresses a huge open question about how the solar wind is energized and helps us understand how the Sun affects its environment and, ultimately, the Earth,” said Yeimy Rivera, co-leader of the study and a postdoctoral fellow at the Smithsonian Astrophysical Observatory, part of Center for Astrophysics | Harvard & Smithsonian. “If this … Read more
NASA announced Tuesday it selected a new instrument to study the Sun and how it creates massive solar eruptions. The agency’s Joint EUV coronal Diagnostic Investigation, or JEDI, will capture images of the Sun in extreme ultraviolet light, a type of light invisible to our eyes but reveals many of the underlying mechanisms of the … Read more
