Conceptual Design of Pressurized Shelters on Lunar Surface
- Abstract: Vinay Dayal Human's next step into space will require long term habitation and shelter on lunar surface, which will only be possible if pressurized habitat is available. Buildings on earth are designed to take advantage of the superior compressive properties of the building material. On the other hand this luxu ... [J. Aerosp.
