On Saturday, Oct. 14, 2023, the Moon will pass between the Earth and Sun, giving people across the United States an opportunity to see an annular solar eclipse, also known as a "ring of fire" eclipse. Lance Bass has some safety tips to share so that you don’t say "Bye, Bye, Bye" to your vision.

Preparing to journey to a metal world, a milestone for a simulated Mars mission, and celebrating an anniversary for our agency … a few of the stories to tell you about – This Week at NASA!

On Saturday, Oct. 14, 2023, the Moon will pass between the Earth and Sun, giving people across the United States an opportunity to see an annular solar eclipse, also known as a "ring of fire" eclipse. Lance Bass has some safety tips to share so that you don’t say "Bye, Bye, Bye" to your vision. WARNING: During an annular eclipse, it is never safe to look directly at the Sun without specialized eye protection designed for solar viewing. Don’t be a space cowboy – learn how to safely view an eclipse:

Our first asteroid sample return mission is back on Earth, a record ride in space for a NASA astronaut, and our Artemis II mission is making prelaunch progress … a few of the stories to tell you about – This Week at NASA

Ahead of an upcoming series of spacewalks scheduled for October 12 and October 20, Dana Weigel, deputy program manager, International Space Station, Elias Myrmo, spacewalk flight director, Faruq Sabur, U.S. spacewalk 89 officer, and Sandra Fletcher, U.S. spacewalk 90 officer, discussed the procedures and tasks for the spacewalks and answered questions from media and social media on October 6. During the spacewalk on Oct. 12, NASA astronaut Loral O’Hara and ESA (European Space Agency) astronaut Andy Mogensen will exit the station’s Quest airlock to collect samples for analysis to see whether microorganisms may exist on the exterior of the orbital complex. They also will replace a high-definition camera on the port truss of the station and conduct other maintenance work to prepare for future spacewalks. During the spacewalk on Oct. 20 O’Hara and NASA astronaut Jasmin Moghbeli will complete the removal of a faulty electronics box, called a Radio Frequency Group, from a communications antenna on the starboard truss of the station and replace one of twelve Trundle Bearing Assemblies on the port truss Solar Alpha Rotary Joint.

This 4K visualization shows the Moon's phase and libration at hourly intervals throughout 2023, as viewed from the Northern Hemisphere. Each frame represents one hour. In addition, this visualization shows the Moon's orbit position, sub-Earth and subsolar points, and distance from the Earth at true scale. Craters near the terminator are labeled, as are Apollo landing sites, maria, and other albedo features in sunlight.

There are millions of asteroids in our solar system, so why is NASA going to the asteroid Psyche? Scientists think this particular asteroid, which orbits the Sun between Mars and Jupiter, could be part of the metal-rich interior of a planetesimal, a building block of the rocky planets in our solar system. Visiting Psyche and studying it up close could help us understand how planets like Mercury, Venus, Earth, and Mars came to be.

On May 16, 2023, NASA’s Juno spacecraft flew past Jupiter’s volcanic moon Io, and then the gas giant soon after. Io is the most volcanically active body in the solar system. Slightly larger than Earth’s moon, Io is a world in constant torment. Not only is the biggest planet in the solar system forever pulling at it gravitationally, but so are its Galilean siblings – Europa and the biggest moon in the solar system, Ganymede. The result is that Io is continuously stretched and squeezed, actions linked to the creation of the lava seen erupting from its many volcanoes.

On Oct. 14, 2023, an annular solar eclipse will cross North, Central, and South America. Visible in parts of the United States, Mexico, and many countries in South and Central America, millions of people in the Western Hemisphere can experience this eclipse. But what is an annular eclipse? Why does it happen? And why does it create a “ring of fire” in the sky?

This video chronicles solar activity from Aug. 12 to Dec. 22, 2022, as captured by NASA’s Solar Dynamics Observatory (SDO). From its orbit in space around Earth, SDO has steadily imaged the Sun in 4K x 4K resolution for nearly 13 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system. With a triad of instruments, SDO captures an image of the Sun every 0.75 seconds. The Atmospheric Imaging Assembly (AIA) instrument alone captures images every 12 seconds at 10 different wavelengths of light. This 133-day time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme-ultraviolet wavelength that shows the Sun’s outermost atmospheric layer: the corona. Compiling images taken 108 seconds apart, the movie condenses 133 days, or about four months, of solar observations into 59 minutes. The video shows bright active regions passing across the face of the Sun as it rotates. The Sun rotates approximately once every 27 days. The loops extending above the bright regions are magnetic fields that have trapped hot, glowing plasma. These bright regions are also the source of solar flares, which appear as bright flashes as magnetic fields snap together in a process called magnetic reconnection. While SDO has kept an unblinking eye pointed toward the Sun, there have been a few moments it missed. Some of the dark frames in the video are caused by Earth or the Moon eclipsing SDO as they pass between the spacecraft and the Sun. Other blackouts are caused by instrumentation being down or data errors. SDO transmits 1.4 terabytes of data to the ground every day. The images where the Sun is off-center were observed when SDO was calibrating its instruments. SDO and other NASA missions will continue to watch our Sun in the years to come, providing further insights about our place in space and information to keep our astronauts and assets safe.

Unidentified Anomalous Phenomena Independent is a specialized field that encompasses events which have not yet been understood from a scientific perspective and lack an accepted explanation. It includes occurrences of nature that are beyond ordinary or conventional phenomena, diverging from what is typically understood. These events are often observed intermittently and are subject to scrutiny by specialists, scientists, and enthusiasts, but their resolution or explanation remains elusive. The study of Unidentified Anomalous Phenomena Independent challenges the boundaries of our knowledge and may pave the way for a deeper understanding in the future." #NASA #SpaceExploration #Astronomy #Science #Space #SpaceScience #Astrophysics
