3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Since childhood, Derrick Bailey always had an early fascination with aeronautics. Military fighter jet pilots were his childhood heroes, and he dreamed of joining the aerospace industry. This passion was a springboard into his 17-year career at NASA, where Bailey plays an important role in enabling successful rocket launches. Bailey is the Launch Vehicle Certification Manager in the Launch Services Program (LSP) within the Space Operations Mission Directorate. In this role, he helps NASA outline the agency’s risk classifications of new rockets from emerging and established space com…

An artist’s concept of NASA’s Orion spacecraft orbiting the Moon while using laser communications technology through the Orion Artemis II Optical Communications System.Credit: NASA/Dave Ryan As NASA prepares for its Artemis II mission, researchers at the agency’s Glenn Research Center in Cleveland are collaborating with The Australian National University (ANU) to prove inventive, cost-saving laser communications technologies in the lunar environment. Communicating in space usually relies on radio waves, but NASA is exploring laser, or optical, communications, which can send data 10 to 100 times faster to the ground. Instead of radio signals, these systems use infrar…

6 Min Read NASA’s Chandra Shares a New View of Our Galactic Neighbor The Andromeda galaxy, also known as Messier 31 (M31), is the closest spiral galaxy to the Milky Way at a distance of about 2.5 million light-years. Astronomers use Andromeda to understand the structure and evolution of our own spiral, which is much harder to do since Earth is embedded inside the Milky Way. The galaxy M31 has played an important role in many aspects of astrophysics, but particularly in the discovery of dark matter. In the 1960s, astronomer Vera Rubin and her colleagues studied M31 and determined tha…

NASA/Bob Hines NASA astronaut Bob Hines took this picture of the waning crescent moon on May 8, 2022, as the International Space Station flew into an orbital sunrise 260 miles above the Atlantic Ocean off the northwest coast of the United States. Since the station became operational in November 2000, crew members have produced hundreds of thousands of images of our Moon and Earth through Crew Earth Observations.

5 Min Read What Are Asteroids? (Ages 14-18) What are asteroids? Asteroids are rocky objects that orbit the Sun just like planets do. In fact, sometimes asteroids are called “minor planets.” These space rocks were left behind after our solar system formed about 4.6 billion years ago. Asteroids are found in a wide range of sizes. For example, one small asteroid, 2015 TC25, has a diameter of about 6 feet – about the size of a small car – while the asteroid Vesta is nearly 330 miles in diameter, almost as wide as the U.S. state of Arizona. Some asteroids even have enough gravity to h…

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) With Voyager 2 in the background, John Casani holds a small U.S. flag that was sewn into the spacecraft’s thermal blankets before its 1977 launch. Then Voyager’s project manager, Casani was first to envision the mission’s Golden Record, which lies before him with its cover at right. NASA/JPL-Caltech During his work on several historic missions, Casani rose through a series of technical and management positions, making an indelible mark on the nation’s space program. John R. Casani, a visionary engineer who served a central role in many of NASA’s historic deep space missions, died on T…

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) In addition to drilling rock core samples, the science team has been grinding its way into rocks to make sense of the scientific evidence hiding just below the surface. NASA’s Perseverance rover uses an abrading bit to get below the surface of a rocky out-crop nicknamed “Kenmore” on June 10. The eight images that make up this video were taken approximately one minute apart by one of the rover’s front hazard-avoidance cameras. NASA/JPL-Caltech On June 3, NASA’s Perseverance Mars rover ground down a portion of a rock surface, blew away the resulting debris, and then went to work studying …
