MOJAVE, Calif. — Ten NASA-sponsored CubeSats are preparing to fly on the agency’s next Educational Launch of Nanosatellites  (ELaNa) mission, making this the first payload carried by Virgin Orbit’s LauncherOne rocket.

With the small satellites safely secured inside the payload fairing, and the fairing mated to the rocket, Virgin Orbit is gearing up for ELaNa 20, the Launch Demo 2 flight from the Mojave Air and Space Port in California.

Evidence for Volcanic Craters on Saturn’s Moon Titan

TUCSON, Ariz. (PSI PR) — Volcano-like features seen in polar regions of Saturn’s moon Titan by NASA’s Cassini spacecraft could be evidence of explosive eruptions that may continue today, according to a new paper by Planetary Science Institute Senior Scientist Charles A. Wood and coauthor Jani Radebaugh of Brigham Young University.

Morphological features such as nested collapses, elevated ramparts, halos, and islands indicate that some of the abundant small depressions in the north polar region of Titan are volcanic collapse craters, according to “Morphologic Evidence for Volcanic Craters near Titan’s North Polar Region” (https://doi.org/10.1029/2019JE006036) that appears in the Journal of Geophysical Research: Planets. A few similar depressions occur near the south pole of Titan.
