Just as avalanches on snowy mountains start with the movement of a small quantity of snow, the ESA-led Solar Orbiter spacecraft has discovered that a solar flare is triggered by initially weak disturbances that quickly become more violent. This rapidly evolving process creates a ‘sky’ of raining plasma blobs that continue to fall even after the flare subsides.

To land on the right foot on the Red Planet, European engineers have been dropping a skeleton of the four-legged ExoMars descent module at various speeds and heights on simulated martian surfaces.

How can scientists estimate the pH level of Enceladus’ subsurface ocean without landing on its surface? This is what a recently submitted study hopes to address as a team of scientists from Japan investigated new methods for sampling the plumes of Enceladus and provide more accurate measurements of its pH levels. This study has the potential to help scientists better understand the subsurface ocean conditions on Enceladus and whether it’s suitable for life as we know it.

NASA will observe its annual Day of Remembrance on Thursday, Jan. 22, which includes commemorating the crews of Apollo 1 and the space shuttles Challenger and Columbia. The event is traditionally held every year on the fourth Thursday of January, as all three astronaut accidents happened around the end of the month.

“On NASA’s Day of Remembrance, we pause to honor the members of the NASA family who lost their lives while pushing the boundaries of exploration and discovery,” said NASA Administrator Jared Isaacman. “We remember them not to retreat from risk, but to respect it — to learn, to improve, and continue onward. Their sacrifice and the strength of their families will forever inspire us as we continue to reach for the stars and pursue the secrets of the universe.”

Isaacman will lead an observance at 1 p.m. EST at Arlington National Cemetery in Virginia, which will begin with a wreath-laying ceremony at the Tomb of the Unknown Soldier, followed by observances for the Apollo 1, Challenger, and Columbia crews.

Several agency centers also will hold observances:

Johnson Space Center in Houston

NASA Johnson will hold a commemoration at 10 a.m. CST at the Astronaut Memorial Grove with remarks by Center Director Vanessa Wyche, NASA astronaut Jasmin Moghbeli, and Cheryl McNair, widow of Challenger astronaut Ronald McNair. The event will have a moment of silence, a NASA T-38 flyover, taps performed by the Texas A&M Squadron 17, and a procession placing flowers at Apollo I, Challenger, and Columbia memorial trees.

Kennedy Space Center in Florida

NASA Kennedy and the Astronauts Memorial Foundation will host a ceremony at the Space Shuttle Atlantis building at Kennedy’s Visitor Complex at 11 a.m. EST. The event will include musical guests, a bell ringing commemoration, a moment of silence, and wreath-laying. Kelvin Manning, deputy director at NASA Kennedy, and Bob Cabana, former NASA associate administrator and Kennedy center director, will provide remarks during the ceremony, which will livestream on the center’s Facebook page.

Ames Research Center in California’s Silicon Valley

NASA Ames will hold a remembrance ceremony at 1 p.m. PST that includes remarks from Center Director Eugene Tu, a moment of silence, and bell ringing commemoration for each astronaut lost in service.

Langley Research Center in Hampton, Virginia

NASA Langley will hold a remembrance ceremony at 1 p.m. EST with acting Center Director Trina Dyal, followed by placing flags at the Langley Workers Memorial.

Marshall Space Flight Center in Huntsville, Alabama

NASA Marshall will hold a candle-lighting ceremony and wreath placement at 9:30 a.m. CST and include remarks from Rae Ann Meyer, Marshall’s acting center director, and Bill Hill, director of Safety and Mission Assurance at Marshall.

Stennis Space Flight Center in Bay St. Louis, Mississippi

NASA Stennis and the NASA Shared Services Center will hold a wreath-laying ceremony and moment of silence at 10:30 a.m. CST with remarks from Center Director John Bailey and Anita Harrell, NASA Shared Services Center executive director.

The agency also is paying tribute to its fallen astronauts with special online content, updated on NASA’s Day of Remembrance, at:
