NASA has provided an update of its Mars Rover Curiosity’s activities in what was called a clay-bearing unit of ​​Mount Sharp on Mars. Clay is associated with water, so the goal of current research is to offer new information to reconstruct the history of Mars, in this case of Gale Crater, where in ancient times there was a lake and now there’s Mount Sharp. Lately, Curiosity has been working near an outcrop that was named “Teal Ridge” and near a rock that was named “Strathdon”, formed by dozens of sedimentary layers that suggest a more dynamic environment than other typical lake sediments.

A few hours ago the SpaceX Dragon spacecraft blasted off atop a Falcon 9 rocket from Cape Canaveral in its CRS-18 (Cargo Resupply Service 18) mission, also referred to as SPX-18. After just over ten minutes it separated successfully from the rocket’s last stage and went en route. This is the 18th mission for the Dragon spacecraft to resupply the International Space Station with various cargoes and then return to Earth, again with various cargoes.

On July 20, 1969, NASA’s Apollo 11 mission’s lunar module Eagle, started on July 16, accomplished the first Moon landing of a manned spacecraft. Mission commander Neil Armstrong and lunar module pilot Edwin “Buzz” Aldrin participated in the landing and spent just over two hours on the surface of the Moon to collect some samples that were brought back to Earth. Once they departed the Moon, the two astronauts rejoined Michael Collins, who remained in orbit in the command module Columbia and returned to Earth on July 24th.
