Total Eclipse: The Big Corona

Most photographs don't adequately portray the magnificence of the Sun's corona. Seeing the corona first-hand during a total solar eclipse is unparalleled. The human eye can adapt to see coronal features and extent that average cameras usually cannot. Welcome, however, to the digital age. The featured image digitally combined short and long exposures taken in Exmouth, Australia that were processed to highlight faint and extended features in the corona during the total solar eclipse that occurred in April of 2023. Clearly visible are intricate layers and glowing caustics of an ever changing mixture of hot gas and magnetic fields in the Sun's corona. Looping prominences appear bright pink just past the Sun's edge. Images taken seconds before and after the total eclipse show glimpses of the background Sun known as Baily's Beads and diamond ring effect. The next total solar eclipse will cross North America in April of 2024.

Apollo 11 moonwalker Buzz Aldrin honored as Air Force one-star, Space Force Guardian

May 16, 2023

Buzz Aldrin already had the moon to his credit. Now he has a star.

The Apollo 11 lunar module pilot, Ph.D. aerospace engineer and colonel in the U.S. Air Force received a promotion to the honorary rank of brigadier general — or one-star officer — during a May 5 ceremony at Los Angeles Air Force Base in California. Lt. Gen. Michael Guetlein, commander of Space Systems Command, presided over the event, which came more than 50 years after Aldrin retired from the Air Force, following 21 years of service.

"Without the courage and dedication of Aldrin, we may never have been afforded the luxury of leading the lifestyle we enjoy today," said Guetlein, addressing the audience. "Over the past 54 years since stepping foot on the moon's surface, he has been an inspiration to a nation, and tireless advocate for space exploration."

In addition to conducting a successful spacewalk as a Gemini astronaut and becoming one of the first men to land and walk on the moon, Aldrin flew 66 combat missions, during which he shot down two Russian MIG-15 fighter jets while serving in Korea. He is the past recipient of the Presidential Medal of Freedom, Congressional Gold Medal, Air Force Distinguished Service Medal, Legion of Merit, two Distinguished Flying Crosses and three Air Medals.

During the ceremony, Aldrin was presented with a general officer's personal flag, which historically has signaled leadership on the battlefield but now represents the presence and rank of a general officer.

"Buzz Aldrin has inspired Americans for generations and is incredibly worthy of this wonderful honor," said Congressman Ken Calvert (CA-41), whose letter to Secretary of the Air Force Frank Kendall led to the promotion. "I am thankful for the Air Force's approval of my request recognizing Buzz for his immeasurable contributions."

"The American exploration and scientific discovery achieved by Buzz is truly remarkable," said Calvert. "Few people who have walked on our planet or soared above it have left a legacy as rich and meaningful as Buzz Aldrin."

In addition to the promotion, Aldrin, 93, was also named an Honorary Guardian within the U.S. Space Force.

"In addition to being promoted to a one-star in the Air Force, Brig. Gen. Aldrin is being made an Honorary Space Force Guardian," said Guetlein. "He has lived a life epitomizing the Space Force Guardian values of character, connection, commitment and courage."

Since its founding in 2019, two NASA astronauts — Michael Hopkins and Nick Hague — have transferred from the Air Force to the Space Force. Aldrin is now the third astronaut-Guardian.

"I will argue that Aldrin was truly one of our first Guardians willing to protect and defend this nation with all that we hold dear," Guetlein said. "He is one of the first Guardians because he has lived a life which epitomizes the very values we strive to live by today."

Aldrin now serves as an example for both services, not just for its members today, but for those still to come.

"This is a story that crosses many generations," said Kendall, while sharing a personal story on how Aldrin influenced his life. "In my home hung on the wall is the New York Times front page when you landed on the moon. I'm going to look at it a little bit differently after today. It's going to mean a little bit more to me."

For his part, Aldrin still has his eyes on the skies — and beyond.

"Sometimes it takes a long time to get where you'd like to go," he said. "It is thrilling that I am still here to see NASA sending brave astronauts to circumnavigate the moon next year, and land astronauts soon thereafter. Now…that's space exploration!"
