The photo of the avalanche was captured by the orbiter through its onboard High Resolution Imaging Science Experiment (HiRISE) camera, which was developed by the Lunar and Planetary Laboratory
of the University of Arizona.
"We think that if there is any life, it likely has to be protected in the subsurface from the radiation," said Ali Bramson, a postdoctoral research associate at the Lunar and Planetary Laboratory
at the University of Arizona and a co-lead author of the new paper.
No one was more delighted with this news than Mildred Shapley Matthews, an astronomer in her own right, who worked many years at the Lunar and Planetary Laboratory
as scientific editor and author for the University of Arizona's Space Science Series on the solar system.
"The rotational period of a planet is one of its fundamental properties," said Karkoschka, a senior staff scientist at the UA's Lunar and Planetary Laboratory
Lewis is Professor Emeritus of planetary science at the University of Arizona's Lunar and Planetary Laboratory
and Vice President of Research at the Space Studies Institute.
"Different people may go different ways with this, and we're really interested to see how the community reacts to it," Michael Sori, co-author of the study and an associate staff scientist in the Lunar and Planetary Laboratory
at the University of Arizona, said in a (https://news.agu.org/press-release/new-study-suggests-possibility-of-recent-underground-volcanism-on-mars/) press release.
A research group in the UA Lunar and Planetary Laboratory
has found evidence in meteorites that hint at the discovery of a previously unknown region within the swirling disk of dust and gas known as the protoplanetary disk -- which gave rise to the planets in our solar system.
Hubbard, professor of planetary sciences at the University of Arizona's Lunar and Planetary Laboratory
in Tucson, used the theoretical data to build a new model for Jupiter's interior.
Hubbard of the University of Arizona's Lunar and Planetary Laboratory
in Tucson, "Right now, we theorists are probably a little hesitant to spin out conjecture on what the paucity of brown dwarfs might mean, because it could be an observational problem."
Jim Scotti, a planetary scientist at the University of Arizona's Lunar and Planetary Laboratory
, said, "It's unlikely this was caused by a meteor, more likely a piece of man-made space debris in low Earth orbit."
Fortunately, the Dutch astronomer Gerard Kuiper had just moved to Tucson to establish the University of Arizona's Lunar and Planetary Laboratory
. So Hartmann decided to head west to pursue his graduate program there.
