Petersen Rock Garden, formerly Petersen's Rock Garden and also known as the Petersen Rock Gardens, [2] [3] is a rock garden and museum on 4 acres (1.6 ha), located between the cities of Bend and Redmond in Deschutes County, Oregon, United States.
This is a list of designs for crewed lunar landers, spacecraft intended to land on the Moon.A key aspect is achieving a soft landing, and for an ascent stage to successfully escape the Moon's gravity. [1]
In the early 1990s, NASA engineers planning a crewed mission to Mars included a Shuttle-C design to launch six non reusable 80-ton segments to create two Mars ships in Earth orbit. After President George W. Bush called for the end of the Space Shuttle by 2010, these proposed configurations were put aside.
Grumman had an excellent design which also seemed too expensive. North American's shuttle had the lowest cost and most realistic cost projections, its design was the easiest for ongoing maintenance, and the Apollo 13 accident involving North American's command and service module demonstrated its experience with electrical system failures.

Surveyor 6 is the sixth lunar lander of the American uncrewed Surveyor program that reached the surface of the Moon.Surveyor 6 landed on the Sinus Medii.A total of 30,027 images were transmitted to Earth.
Following completion of six month Lunar mission, departed selenocentric orbit for Earth–Sun L2 Lagrangian point [75] and subsequently flew by asteroid 4179 Toutatis for a close encounter with the asteroid at a distance of 3.2 kilometers and a relative velocity of 10.73 km/s.

The Apollo 13 Lunar Module functioned as a lifeboat to provide life support and propulsion to keep the crew alive for the trip home, when their CSM was disabled by an oxygen tank explosion en route to the Moon. The six landed descent stages remain at their landing sites; their corresponding ascent stages crashed into the Moon following use.
The Dynetics Autonomous Logistics Platform for All-Moon Cargo Access (ALPACA)—also known as Dynetics HLS [1] —(ILV) is a human spaceflight lunar lander design concept proposed in 2020/21 for the NASA Human Landing System (HLS) component of the Artemis program.
