I am Artemis: John Campbell

John Campbell, a logistics engineer at NASA’s Marshall Space Flight Center, stands on NASA’s Pegasus barge July 15. NASA

How do you move NASA’s SLS (Space Launch System) rocket’s massive 212-foot-long core stage across the country? You do it with a 300-foot-long barge. However, NASA’s Pegasus barge isn’t just any barge. It’s a vessel with a history, and John Campbell, a logistics engineer for the agency based at NASA’s Marshall Space Flight Center in Huntsville, Alabama, is one of the few people who get to be a part of its legacy.

For Campbell, this journey is more than just a job – it’s a lifelong passion realized. “Ever since I was a boy, I’ve been fascinated by engineering,” he said. “But to be entrusted with managing NASA’s Pegasus barge, transporting history-making hardware for human spaceflight across state lines and waterways – is something I never imagined.”

NASA has used barges to ferry the large,and heavy hardware elements of its rockets since the Apollo Program. Replacing the agency’s Poseidon and Orion barges, Pegasus was originally crafted for the Space Shuttle Program and updated in recent years to help usher in the Artemis Generation and accommodate the mammoth dimensions of the SLS core stage. The barge plays a big role in NASA’s logistical operations, navigating rivers and coastal waters across the Southeast, and has transported key structural test hardware for SLS in recent years.

Campbell grew up in Muscle Shoals, Alabama. After graduating from the University of Alabama with a degree in mechanical engineering, he ventured south to Panama City, Florida, where he spent a few years with a heating, ventilation, and air conditioning consulting team. Looking for an opportunity to move home, he applied for and landed a contractor position with NASA and soon moved to his current civil service role.

With 17 years under his belt, Campbell has many fond memories during his time with the agency. One standout moment was witnessing the space shuttle stacked in the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. But it’s not all about rockets and launch pads for Campbell. When he isn’t in his office making sure  Pegasus has everything it needs for its next trip out, he is on the water accompanying important pieces of hardware to their next destinations. With eight trips on Pegasus under his belt, the journey never gets old.

“There is something peaceful when you look out and it’s just you, the water, one or two other boats, and wildlife,” Campbell said. “On one trip we had a pod of at least 20 dolphins surrounding us. You get to see all kinds of cool wildlife and scenery.” From cherishing special moments like this to ensuring the success of each journey, Campbell recognizes the vital role he plays in the agency’s goals to travel back to the Moon and beyond and does not take his responsibility lightly.

“To be a part of the Artemis campaign and the future of space is just cool. I was there when the barge underwent its transformation to accommodate the colossal core stage, and in that moment, I realized I was witnessing history unfold. Though I couldn’t be present at the launch of Artemis I, watching it on TV was an emotional experience. To see something you’ve been a part of, something you’ve watched evolve from mere components to a giant spacecraft hurtling into space – it’s a feeling beyond words.”

NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

NASA’s Juno Mission Captures the Colorful and Chaotic Clouds of Jupiter

Image data: NASA/JPL-Caltech/SwRI/MSSS
Image processing by Gary Eason © CC BY

During its 61st close flyby of Jupiter on May 12, 2024, NASA’s Juno spacecraft captured this color-enhanced view of the giant planet’s northern hemisphere. It provides a detailed view of chaotic clouds and cyclonic storms in an area known to scientists as a folded filamentary region. In these regions, the zonal jets that create the familiar banded patterns in Jupiter’s clouds break down, leading to turbulent patterns and cloud structures that rapidly evolve over the course of only a few days.

Citizen scientist Gary Eason made this image using raw data from the JunoCam instrument, applying digital processing techniques to enhance color and clarity.

At the time the raw image was taken, the Juno spacecraft was about 18,000 miles (29,000 kilometers) above Jupiter’s cloud tops, at a latitude of about 68 degrees north of the equator.

JunoCam’s raw images are available for the public to peruse and process into image products at https://missionjuno.swri.edu/junocam/processing. More information about NASA citizen science can be found at https://science.nasa.gov/citizenscience and https://www.nasa.gov/solve/opportunities/citizenscience.

Explorers on the Moon: Apollo 11 Landing

NASA

On July 20, 1969, astronauts Neil Armstrong and Buzz Aldrin landed on the Moon in the lunar module “Eagle.” Afterward, Aldrin posed for this photo, taken by Armstrong, beside the United States flag.

The Apollo 11 mission’s main goal was to perform a crewed lunar landing and return to Earth. The crew also conducted scientific exploration of the Moon’s surface and deployed a television camera to transmit signals to Earth. Armstrong and Aldrin spent 21 hours and 36 minutes on the Moon. They explored the surface, took extensive photographs of the lunar terrain and each other, and collected lunar surface samples.

The two moonwalkers left behind commemorative medallions bearing the names of the three Apollo 1 astronauts who lost their lives in a launch pad fire, and two cosmonauts who also died in accidents, on the lunar surface. Also left on the Moon were several tokens of world peace.
