The Lunar Space Elevator, a Near Term Means to Reduce Cost of Lunar Access
A Lunar Space Elevator [LSE] can be built today from existing commercial polymers; manufactured, launched and deployed for less than $2B. A prototype weighing 48 tons with 100 kg payload can be launched by 3 Falcon-Heavy's, and will pay for itself in 53 sample return cycles within one month. It reduces the cost of soft landing on the Moon at least threefold, and sample return cost at least ninefold. Many benefits would arise. A near side LSE can enable valuable science mission, as well as mine valuable resources and ship to market in cislunar space, LEO and Earth's surface. A far-side LSE can facilitate construction and operation of a super sensitive radio astronomy facility shielded from terrestrial interference by the Moon. The LSE would facilitate substantial acceleration of human expansion beyond LEO.

Scientific Return of a Lunar Elevator
The concept of a space elevator dates back to Tsilokovsky, but they are not commonly considered in near-term plans for space exploration, perhaps because a terrestrial elevator would not be possible without considerable improvements in tether material. A Lunar Space Elevator (LSE), however, can be built with current technology using commercially available tether polymers. This paper considers missions leading to infrastructure capable of shortening the time, lowering the cost and enhancing the capabilities of robotic and human explorers. These missions use planetary scale tethers, strings many thousands of kilometers long stabilized either by rotation or by gravitational gradients. These systems promise major reduction in transport costs versus chemical rockets, in a rapid timeframe, for a modest investment. Science will thus benefit as well as commercial activities.

Lunar surface operations. Volume 3: Robotic arm for lunar surface vehicle
1993
A robotic arm for a lunar surface vehicle that can help in handling cargo and equipment, and remove obstacles from the path of the vehicle is defined as a support to NASA's intention to establish a lunar based colony by the year 2010. Its mission would include, but not limited to the following: exploration, lunar sampling, replace and remove equipment,

What are the important benefits provided to the United States and other countries by human spaceflight endeavors? The ability to place humans in space is exciting to the public, and demonstrates the technological maturity and stature of each spacefaring nation. Such a visible and peaceful demonstration of cutting edge technology fosters foreign policy by showing strength without engaging in conflict i . Human spaceflight sparks the imagination and serves an instinctive need to explore. Astronauts are ambassadors for all of humanity in a very personal way. Men and women in space suits inspire people – of all cultures and demographics – to achieve excellence, to believe in a common cause and to pursue a noble goal. Furthermore, humans in space have unique abilities and attributes (eyes, fingers, and onsite reasoning) to pursue scientific research and commercial development that cannot be achieved by robotic means. American leadership, as demonstrated by the continuous success of human...

Preliminary Design Considerations for Access and Operations in Earth-Moon L1/L2 Orbits
2013
Within the context of manned spaceflight activities, Earth-Moon libration point orbits could support lunar surface operations and serve as staging areas for future missions to near-Earth asteroids and Mars. This investigation examines preliminary design considerations including Earth-Moon L1/L2 libration point orbit selection, transfers, and stationkeeping costs associated with maintaining a spacecraft in the vicinity of L1 or L2 for a specified duration. Existing tools in multi-body trajectory design, dynamical systems theory, and orbit maintenance are leveraged in this analysis to explore end-to-end concepts for manned missions to Earth-Moon libration points.
