LUNAR BASES

Strategies, Concepts, Prospects and Plans

H.H.Koelle

ISBN 3-8322-1728-2/ SHAKER Verlag, Aachen, 2003

Abstract:

Possible developments of human space flight beyond the International Space Station in low earth orbit are

described. The present state-of-the-art and prospects of lunar development is summarized. The rationale of entering

a new phase of lunar development is presented, including the social and political background. The essential

functions and associated facilities of an initial lunar base are defined. It is shown that the space transportation

system, providing the logistic support of a lunar base, is the bottleneck of new evolutionary steps. A feasible

schedule and associated detailed cost estimates are presented. Options available such as a 'Lunar Outpost' and/or

'Initial Lunar Base' are discussed. A 10-year development and 30-year operational program leading to a lunar base

with up to 100 people, is recommended as a reference model for future considerations. –

CONCEPTUAL DESIGN OF A LUNAR BASE

H.H.Koelle, H.N.Mertens

ISBN 3-8322-2428-9/ SHAKER Verlag, Aachen, 2004

Abstract:

Current plans will probably lead to the establishment of an initial lunar base during the next two decades. Detailed

proposals for a lunar installation are putting some substance in such advanced planning. For this reason the

rationale, base concepts, performance, schedules and cost are the subjects addressed. This documentation illustrates

the road from a parametric analysis to a conceptual design of an initial lunar base. The approach taken is a detailed

analysis of one representative lunar base concept that could be used as a baseline for further discussion and analysis.

The program envisioned is based a ten-year planning and development period, followed by a 30-year initial

operational phase. This concept would be leading to a lunar crew of 85 lunar astronauts at the end of the assumed

life cycle. A near term representative space transportation system, to be developed in conjunction with base

facilities, would provide the logistic support to the lunar base. Cost estimates of the 40-year program are in the

order of $ 90 B. An average annual outlay below 3 B $ indicates its financial affordability, particularly if it would be

realized on an international basis.

LUNAR SPACE TRANSPORTATION SYSTEMS

H.H.Koelle

ISBN 3-8322-2746-6/ SHAKER Verlag, Aachen, 2004

Abstract

The present stable of launch vehicles represents the state-of-the-art of the sixties or seventies. They are expendable

vehicles with the exception of the SPACE SHUTTLE which is partly reusable. Payload capabilities reach from a few

hundred kilograms to about twenty tons to low Earth orbit. Cost per launch are about $ 50 M for a DELTA vehicle

up to $ 550 M for a crewed SPACE SHUTTLE. The cost effectiveness is on the order of 10,000 $/kg for low Earth

orbits. Fully reusable launch vehicles with larger payload capabilities are needed to expand space activities in this

next century. This paper analyses some of the most attractive options of space transportation systems with

emphasis on heavy lift launchers for lunar and planetary crewed missions. It is shown that payload capabilities can

be increased and specific transportation costs can be decreased by an order of magnitude. This capability to

transport people and equipment to the lunar surface in greater numbers makes the acquisition of a permanent lunar

base a feasible and affordable program of the near future. –
