Palmetto crater is a small crater in the Descartes Highlands of the Moon visited by the astronauts of Apollo 16. The name of the crater was formally adopted by the IAU in 1973. [1]

On April 21, 1972, the Apollo 16 Lunar Module (LM) Orion landed about 1.5 km south of Palmetto, which is between the prominent North Ray and South Ray craters. The astronauts John Young and Charles Duke explored the area over the course of three EVAs using a Lunar Roving Vehicle, or rover. They drove along the rim of Palmetto on EVA 3, on their way to North Ray, but did not stop. As they drove by, Duke said "There's a good ejecta blanket of half-meter-size boulders around the rim of Palmetto into some of these secondary craters here." [2] On the way back to the lunar module from North Ray, Duke took a sequence of photos of Palmetto while riding on the rover.

The crater was also used as a landmark by Apollo astronauts on previous missions. It was designated landmark DE-1/12, [3] and astronaut Dick Gordon tracked it photographically on revolutions 42 and 44 of the Apollo 12 mission.

Palmetto crater is approximately 760 m in diameter and approximately 130 m deep. [4] The similar-sized crater Gator lies 1 km to the southeast.

Palmetto cuts into the Cayley Formation of Imbrian age. [5]

Apollo 16 was the tenth crewed mission in the United States Apollo space program, administered by NASA, and the fifth and penultimate to land on the Moon. It was the second of Apollo's "J missions", with an extended stay on the lunar surface, a focus on science, and the use of the Lunar Roving Vehicle (LRV). The landing and exploration were in the Descartes Highlands, a site chosen because some scientists expected it to be an area formed by volcanic action, though this proved not to be the case.

<span class="mw-page-title-main">Shorty (crater)</span> Lunar crater

Shorty is a feature on Earth's Moon, an impact crater in the Taurus–Littrow valley. Astronauts Eugene Cernan and Harrison Schmitt visited it in 1972, on the Apollo 17 mission. It is the location of the famous "orange soil", which geologists believe to be small bits of rapidly-cooled molten rock ejected in a fire fountain. It is about 110 meters in diameter and up to 14 m (15 yd) deep.

Shorty Crater is about 14 m deep. Based on our investigations at the site and later examination of photographs, the impact that formed it penetrated, in order, regolith on the avalanche deposit, the avalanche deposit, regolith on a basalt flow, a basalt flow overlying and protecting the orange and black glass layers, the orange and black glass layers, regolith on a second basalt flow, and, finally, the upper portion of that second flow. Orange and black glass clods and basalt boulders are spread throughout the ejecta blanket surrounding Shorty.
