Pluto and Its Moons: Charon, Nix, and Hydra - NASA Science (.gov)

A new analysis led by Southwest Research Institute (SwRI) suggests that liquid nitrogen may be moving upward through cracks and reaching the surface of Pluto near the northern edge of Sputnik Planitia, the enormous heart-shaped glacier that dominates part of the dwarf planet. The findings provide the first evidence that liquid has flowed on Pluto in relatively recent times. The research is based on observations from NASA's New Horizons spacecraft and was led by SwRI Associate Vice President Dr. Alan Stern, principal investigator of the New Horizons mission.

NASA's record-breaking New Horizons spacecraft has awoken from a 321-day hibernation in "good health" as it resumes unprecedented science at the solar system's edge.

A new James Webb Space Telescope study has identified a very specific wavelength of light missing from both Pluto and Saturn's largest moon, Titan. The surprising signal suggests that these worlds harbor an unknown molecule that has not been seen anywhere in the solar system or beyond.

Concept of JAXA’s MMX spacecraft during its Mars orbit insertion, with the moon Phobos in the background. A pioneering mission to study a pair of Martian moons and return a 10-gram soil sample to Earth is being prepared for launch Oct. 19 from Japan’s Tanegashima Space Center. If successful, the Martian Moons Exploration (MMX) mission will add the first samples of Martian real estate to the world’s...
