Description: This is a high-resolution oblique view of the northeastern edge of the delta deposit in Jezero crater, the landing site for the Perseverance Mars rover. In the foreground, buttes of delta material stand above the crater floor. On the left and in the middle of this image, the layered rocks of the delta deposit are visible. These may be lake bed or river

This animation shows a rotating globe of the new Unified Geologic Map of the Moon with shaded topography from the Lunar Orbiter Laser Altimeter (LOLA). This geologic map is a synthesis of six Apollo-era regional geologic maps, updated based on data from recent satellite missions. It will serve as a reference for lunar science and future human missions to the Moon. Credit:

Before landing on the surface of the moon in 1969, astronauts Neil Armstrong and Buzz Aldrin needed a training ground that matched their destination's cratered surface.

In the U.S., that turned out to be northern Arizona. Starting in 1967, the U.S. Geological Survey used hundreds of pounds of dynamite to blast holes into the surface of ancient lava fields south of

High-spatial-resolution airborne images of the Tern Lake area from 1994, 2006, and 2017. The area of bright pixels identified in the Landsat-8 thermal infrared image corresponds to a newly emerging area of warm ground and tree kills about 32,500 m² (8 acres, or 4 soccer fields) in area. The air photo from 2006 shows the beginnings of a tree kill zone. The black

Landsat-8 nighttime thermal infrared image from April 2017 showing the Tern Lake area. In Yellowstone, temperatures are extremely cold at night in the winter, and most lakes are frozen (dark pixels). West Tern Lake seems to be thawing here - perhaps it receives some thermal waters from nearby hot springs. The patch of bright (warm) pixels between West Tern Lake and the

Map of thermal areas in Yellowstone National Park. Most of Yellowstone's more than 10,000 thermal features are clustered together into about 120 distinct thermal areas (shown in red). Lakes are blue. The Yellowstone Caldera is solid black and the resurgent domes are dotted black. Roads are yellow. The orange box shows the location of the Tern Lake thermal area.

In preperation for Apollo 15, David Scott and James Irwin trained with a training version of the Lunar Rover known as the "Grover". Apollo 15 was the first mission to bring a rover. This allowed the astronauts to cover a larger distance and explore a larger area.
