Read about the recent stunning image of Jupiter’s moon, Io, obtained by NASA’s Juno spacecraft on Dec 30, 2023!

Jupiter’s first Galilean moon, Io, is one of the most fascinating objects in the entire solar system, exhibiting hundreds of volcanoes that send molten lava hundreds of miles into space, some of which come raining back down onto the small moon’s surface. While Io was explored in depth with NASA’s Galileo spacecraft during the late 1990s and early 2000s, Io hasn’t been imaged up close since then. But NASA’s Juno spacecraft recently broke this dry spell when it passed within 930 miles (1,500 kilometers) of Io’s surface on December 30, 2023, capturing stunning images of active volcanic plumes and several lava fields.

The MMU was the highlight of the STS-41B mission as demonstrated by the stunning mission photographs that graced the cover of Aviation Week & Space Technology, not once, not twice, but three times.

“Hoot” Gibson, the flight’s pilot, shot the photograph featured on the February 20, 1984, issue of the magazine from the crew cabin. Gibson remembered he was the only one on the crew that “had absolutely nothing to do” as McCandless made his way out into space, so he picked up a Hasselblad camera and began documenting the events. When he first looked through the camera’s viewfinder, he could not believe what an incredible sight it was to see McCandless untethered, floating above the Earth. Gibson wanted to capture what he was seeing and remembered how meticulous he was. For each photograph he took three light meter readings and checked the focus four times. In the crew’s photography training he learned that an off-kilter horizon looked wrong and was not pleasing to the eye. That presented a slight problem because Challenger was at a 28.5-degree inclination, so he “tilted the camera to put the horizon level in the pictures.”
