NASA Mars Pathfinder Twin Peaks
NASA’s Mars Pathfinder mission arrived July 4, 1997 on the Red Planet. Its small rover, named Sojourner after abolitionist Sojourner Truth, spent 83 days of an initially planned 7-day mission, exploring the Martian terrain. A multitude of images were captured, while also taking chemical, atmospheric and other measurements. The final data transmission was received from Pathfinder at 6:23 am EST on September 27, 1997.

Korolev Crater ESA Mars Ice
The European Space Agency has created a short film of the Korolev crater using an image mosaic made from single orbit observations from the High Resolution Stereo Camera (HRSC) on Mars Express. These images combines data from the HRSC nadir and color channels, with the former aligned perpendicular to the surface of Mars, as if looking straight down. Next, the mosaic was combined with topography information from the stereo channels of HRSC to generate a three-dimensional landscape.

Elon Musk announced that Starship prototype SN4 successfully passed a cryogenics test on Sunday at a SpaceX site in Texas. This is a milestone for the project as it will eventually send payload to the Red Planet. It also marks the first full-scale Starship prototype to pass this critical test involving filling the ship with liquid nitrogen to ensure it’s capable of surviving in-flight pressure conditions.

NASA Curiosity Rover Selfie Mars
NASA’s Curiosity Mars rover took a new selfie on Oct. 11, 2019 at “Glen Etive”, which is part of the “clay-bearing unit,” and this mosaic was stitched together from 57 individual images taken by a camera on the end of its robotic arm. If you look in the left foreground you’ll see the two holes that Curiosity drilled – named “Glen Etive 1” (right) and “Glen Etive 2” (left) – that were used to analyze the chemical composition of rock samples by using the drill to turn them into powder before dropping the samples into a portable lab in its belly called Sample Analysis at Mars (SAM).
