Business attire, headsets, and multiple computer monitors are a much different backdrop than hiking gear, rock hammers, and the volcanic fields of Iceland. For Kelsey Young of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and Trevor Graff and Angela Garcia of NASA’s Johnson Space Center in Houston, comfort and skill across both environments have made them uniquely suited to be certified as NASA’s first Artemis II science officers.
The integration of science operations into human spaceflight dates back to Apollo, but Artemis introduces a new dedicated position in NASA’s Mission Control, marking an evolution of how science is embedded in mission operations.
“The science officer is the senior flight controller responsible for lunar science and geology objectives during Artemis missions,” said Young, who also serves as NASA’s Artemis II lunar science lead. “They will integrate with all the other console disciplines and ensure NASA’s lunar science objectives are seamlessly integrated into mission execution.”
The front room of Mission Control is filled with consoles, or workstations, each dedicated to a particular system or function of the mission. Flight controllers at each console monitor areas such as communications, life support, propulsion, and now, science. Many of the console positions are supported by larger teams of experts who work from either different “back rooms” at NASA’s Johnson Space Center in Houston, or other locations.
Young, Garcia, and Graff completed months of flight controller training, testing, and certification simulations in Mission Control, while also executing geology and lunar observation trainings and integrated simulations with the astronauts.

“One of the most exciting, challenging, and rewarding components of the process are the simulations, where we tested our skills and knowledge while immersed in very realistic mission scenarios,” said Graff.
The simulations often included the Artemis II astronauts and covered the lunar flyby portion of the mission, planned for Monday, April 6, during which time the crew will take photographs of the Moon and record audio of their observations. They will be the eyes of the lunar scientists on Earth and have gone through geology training in the classroom and in the field to be able to capture as much information as possible during their pass around the far side of the Moon. Young said the astronauts have worked incredibly hard at building their lunar science toolboxes, studying lunar geography, traipsing across lunar-like landscapes in Iceland, and cultivating their ability to provide scientifically impactful descriptions of the Moon.

“After so many months of hearing their descriptions of lunar visualizations during simulations, I’m most excited for the very first time I hear them describing the actual Moon out of the Orion windows,” said Young. “Hearing the excitement and scientific meaning behind their descriptions will be an incredible moment.”
Human eyes and brains are highly sensitive to subtle changes in color, texture, and other surface characteristics. Having astronaut eyes observe the lunar surface directly, in combination with the context of all the advances that scientists have made about the Moon over the last several decades, may uncover new discoveries and a more nuanced appreciation for the features on the surface of the Moon. While Artemis II will not land on the lunar surface, its contributions to lunar science are significant.
“The crew will be exploring through observation—a foundational scientific tool,” said Garcia.
As the astronauts make those observations, their photos and recorded audio will be fed down to two science back rooms at NASA Johnson, the Science Evaluation Room and Science Mission Operations Room. Experts in these rooms will provide data analysis and strategic guidance in real time to the science officer in Mission Control. These processes represent a major component of Artemis II as a test flight: refining science mission operations.
This mission will test the lunar science team’s workflows, technical requirements, and integration into Mission Control. Lessons learned during Artemis II will pave the way for lunar science operations for future Artemis missions. Young explained that science integration into human spaceflight has a long, rich history. While there was no science representative in the front room of Mission Control during Apollo, there was a geology back room onsite at Johnson. As Apollo missions progressed, the structure of integrating with the rest of the flight control team evolved and the footprint expanded as the science capability of each mission grew.
Garcia said she is humbled, honored, and grateful to be a part of the flight control team and to have trained the astronauts. The Moon is something everyone, everywhere, can see and connect with, according to Young.
“I hope people all over the world can be inspired by this push away from our planet,” said Young, “I also hope they remember the Moon, how much we still have to learn about our nearest neighbor but also the special place it holds to people everywhere.”

Today marks the 100th anniversary of the birth of Virgil I. “Gus” Grissom, born April 3, 1926, in Mitchell, Indiana. As one of NASA’s first seven astronauts, he became America’s second astronaut to fly in space when he launched aboard the Liberty Bell 7 spacecraft on July 21, 1961, just weeks after Alan Shepard’s historic first Project Mercury spaceflight.
In this photo, Grissom is seen enjoying a meal aboard the recovery ship, USS Randolph, following his 15-minute suborbital mission. Although the flight itself was smooth, the situation turned dangerous after splashdown when the capsule’s hatch blew prematurely and the spacecraft began flooding with water. Grissom escaped, but his spacesuit also filled with water as the recovery helicopters attempted to save his sinking spacecraft. He was successfully rescued, but the Liberty Bell 7 sank to the ocean floor.
Grissom made history again in March 1965 as the first NASA astronaut to fly in space twice, serving as commander of Gemini III, the first crewed Gemini mission, alongside John Young. Reflecting on this test flight, he wrote, “To our intense satisfaction we were able to carry out these maneuvers almost exactly as planned… The longer we flew, the more jubilant we felt. We had a really fine spacecraft, one we could be proud of in every respect.”
One year later, in March 1966, NASA announced that Grissom had been selected to command the first Apollo mission, with crewmates Edward White and Roger Chaffee. On January 27, 1967, tragedy struck during a preflight test at Cape Kennedy when fire swept through the command module. Grissom, White, and Chaffee lost their lives in an accident that stunned the nation and shook NASA to its core.
Just weeks before the tragedy, Grissom wrote: “There will be risks, as there are in any experimental program, and sooner or later, we’re going to run head-on into the law of averages and lose somebody. I hope this never happens, and… perhaps it never will, but if it does, I hope the American people won’t think it’s too high a price to pay for our space program.”

At the top of the planet, the cap of sea ice across Arctic waters grows and shrinks with the seasons, usually reaching its annual maximum extent in March. In 2026, this peak occurred on March 15, when the extent reached 14.29 million square kilometers, matching the lowest maximum observed since satellite monitoring began in 1979. One of the key areas contributing to the low maximum this year was the Barents Sea.
The Barents Sea lies at the periphery of the Arctic Ocean, bordered to the northwest by the Norwegian archipelago of Svalbard, and to the northeast and east by the Russian islands of Franz Josef Land and Novaya Zemlya, respectively. It is one of more than a dozen subregions—including the Central Arctic Ocean and nearby seas, bays, and waterways—across which scientists use remote sensing to track sea ice. The region is important for fisheries, shipping routes, and scientific research.
On March 17, 2026, the Terra satellite captured this image of the northern Barents Sea. Near Franz Josef Land, broken sea ice drifted near areas of open water closer to Novaya Zemlya. The region is often cloudy, as it was that day, but most clouds were thin enough to reveal the sea ice and water below.
In addition to the low extent, data from NASA’s ICESat-2 satellite indicate that Barents sea ice in mid-March 2026 was also very thin, according to Nathan Kurtz, chief of the Cryospheric Sciences Laboratory at NASA’s Goddard Space Flight Center.
Previous years, such as 2021 and 2025, also saw especially thin ice around the time of the maximum. “What was striking this year, however, was that the ice was also completely melted away in more of the Barents Sea, in addition to areas of thinning spreading northward,” Kurtz said.
On the opposite side of the Arctic, the Sea of Okhotsk also contributed to the low total sea ice extent across the Arctic in March 2026. But the factors driving the losses differ between the two regions.
In the Barents, studies have shown that the main driver is large-scale atmospheric circulation, with winds channeling warm, humid air from the North Atlantic straight into the area, accelerating melt. These winds can be influenced by tropical weather thousands of miles away. Disturbances originating over the Maritime Continent near Indonesia can “send ripples through the atmosphere that reach the Arctic within one to two weeks,” Kurtz said.
In contrast, the Sea of Okhotsk mostly has thin, seasonal ice that changes thickness from year to year. Local winds play a big role, sometimes pushing the ice together to create thicker, ridged areas, and other times spreading it out, making it thinner. Because of this, the ice loss there is mainly driven by local weather, unlike in the Barents Sea, where distant atmospheric forces have a greater impact.
