An image captured by the HiRISE camera on April 22 showed a series of strange chevron symbols that appear to resemble the iconic "Star Trek" Starfleet logo on a Martian sand dune in the southeast Hellas Planitia
Using satellite images, researchers spotted fields of ghost dunes pitting the surface of two different regions on Mars: 480 potential dune molds at Noctis Labyrinthus, a mazelike region of plateaus and canyons, and 300 in the Hellas Planitia
, a smooth 4-billion-year-old crater.
These remanent fields are absent from Hellas Planitia
as well as several other large impact basins.
A series of sedimentary deposits indicates the presence of large standing bodies of water in Hellas Planitia
located in the southern hemisphere of Mars, said by Dr.
The space agency's (https://www.nasa.gov/image-feature/jpl/pia22052/squiggles-in-hellas-planitia) Jet Propulsion Laboratory shared a photo of the lines, made in Mars' Hellas Planitia
, that its Mars Reconnaissance Orbiter took as it was surveying the area - part of an almost 1,400-mile-wide impact basin on the planet's southern hemisphere that is the largest one ever found in the solar system.
Even at the bottom of the Hellas Planitia
, the largest impact crater in the solar system, the pressure is estimated at just 1.1% of Earth standard.
