Virgil I. “Gus” Grissom

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.”

Barents Sea Tied to Low Arctic Sea Ice

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.

NASA’s Artemis II Mission Leaves Earth Orbit for Flight around Moon

For the first time in more than 50 years, astronauts on a NASA mission are bound to fly around the Moon after successfully completing a key burn of Orion’s main engine.

With the approximately six-minute firing of the spacecraft’s service module engine on Thursday, known as the translunar injection burn, Orion and its crew of NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen accelerated to break free of Earth’s orbit and began the outbound trajectory toward Earth’s nearest neighbor.

“Today, for the first time since Apollo 17 in 1972, humans have departed Earth orbit. Reid, Victor, Christina, and Jeremy now are on a precise trajectory toward the Moon. Orion is operating with crew for the first time in space, and we are gathering critical data, and learning from each step,” said Dr. Lori Glaze, acting associate administrator for the Exploration Systems Development Mission Directorate at NASA Headquarters in Washington. “Each milestone we reach marks meaningful progress on the path forward for the Artemis program. While we have eight intensive days of work ahead, this is a big moment, and we’re proud to share it with the world.” 

NASA’s SLS (Space Launch System) rocket and Orion spacecraft lifted off from Launch Pad 39B at the agency’s Kennedy Space Center in Florida at 6:35 p.m. EDT on April 1, sending the four astronauts on a planned 10-day test flight around the Moon and back.

After reaching space, Orion deployed its four solar array wings, enabling the spacecraft to receive energy from the Sun, while the crew and engineers on the ground immediately began transitioning the spacecraft from launch to flight operations to start checking out key systems.

About 49 minutes into the test flight, the SLS rocket’s upper stage fired to put Orion into an elliptical orbit around Earth. A second planned burn by the stage propelled Orion, which the crew named “Integrity,” into a high Earth orbit extending about 46,000 miles above the Earth for about 24 hours of system checkouts. After the burn, Orion separated from the stage, flying free on its own.

The crew then conducted a manual piloting demonstration to test Orion’s handling qualities using the ICPS (interim cryogenic propulsion stage) as a docking target.

At the conclusion of the demonstration, Orion executed an automated departure burn to safely back away from the ICPS, after which the stage performed its own disposal burn and re-entered Earth’s atmosphere over a remote region of the Pacific Ocean.

Prior to its re-entry, four small CubeSats were deployed from SLS rocket’s Orion stage adapter.

Other tasks completed so far include a transition to the Deep Space Network for communications, the crew becoming acclimated to the space environment, completing their first rest periods, performing the first flywheel exercise, restoring the spacecraft’s toilet to normal operations, and configuring the spacecraft for the translunar injection burn.

During a planned lunar flyby on Monday, April 6, the astronauts will take high resolution photographs and provide their own observations of the lunar surface, including areas of the far side of the Moon never seen directly by humans. Although the lunar far side will only be partially illuminated during the flyby, the conditions should create shadows that stretch across the surface, enhancing relief and revealing depth, ridges, slopes, and crater rims that are often difficult to detect under full illumination.

Following a successful lunar flyby, the astronauts will return to Earth and splash down in the Pacific Ocean off the coast of San Diego.

As part of a Golden Age of innovation and exploration, NASA will send Artemis astronauts on increasingly challenging missions to explore more of the Moon for scientific discovery, economic benefits, and to build on our foundation for the first crewed missions to Mars.
