2013年9月6日 · The LER is an air-launched, winged vehicle designed to carry a 1500 pound payload into a 250 nautical mile orbit. The LER is launched from the back of a 747-100B at 35,000 feet and a Mach number of 0.8. Three staged solid propellant motors offer safe ground and flight handling, reliable operation, and decreased fabrication cost.

The Space Exploration Vehicle (SEV) is a modular vehicle concept developed by NASA from 2008 to 2015. It would have consisted of a pressurized cabin that could be mated either with a wheeled chassis to form a rover for planetary surface exploration (on the Moon and elsewhere) or to a flying platform for open space missions such as servicing ...

The Low Earth orbit Raider (LER) is an answer to this need. The LER is an air-launched, winged vehicle designed to carry a 1500 pound payload into a 250 nautical mile orbit. The LER is launched from the back of a 747-100B at 35,000 feet and a Mach number of 0.8. Three staged solid propellant motors offer safe ground and flight handling, reliable

2010年9月27日 · Forty-three years later, NASA human factors engineers conducted a similar study using the Lunar Electric Rover (LER) in a dynamic real-world lunar simulation at the Black Point Lava Flow in Arizona. The objective of the study was to obtain human-in-the-loop performance data on the vehicle s interior volume with respect to human-system ...

2010年1月25日 · Join NASA at Desert RATS, or Research and Technology Studies, in Arizona to test drive the Lunar Electric Rover, or LER. Discover how LER's turning radius, ability to move in multiple...

NASA is still building on the lessons learned during the Apollo missions, and is also incorporating the experiences of operating unmanned rovers on Mars. One pressurized rover concept is the Lunar Electric Rover, or LER. The chassis, which serves as …

It’s the Lunar Electric Rover (LER), a prototype for the vehicle that NASA hopes to send with astronauts to the moon by 2020—a “home on wheels,” he calls it. The...

Currently, the National Aeronautics and Space Administration s (NASA) is investigating two lunar rover configurations to meet such a requirement. Under the Lunar Electric Rover ( LER) project, a comparison study between the unpressurized rover (UPR) and the small pressurized rover (SPR) was conducted at the Black Point Lava Flow in Arizona.

Abstract: This paper describes the design and control of the first generation active suspension for NASA's Chariot rover and Lunar Electric Rover (LER). Within the paper is a general overview of the needs and benefits of active suspensions for crew mobility systems on the lunar surface.

2009年8月17日 · The Lunar Electric Rover (LER) is equipped with a time and space saving concept called suit ports. The suit ports are located on the aft bulkhead of the LER, and are designed to allow astronauts to quickly go from driving in a shirtsleeve environment to Extravehicular Activity (EVA) in their space suits.
