  Voyager Station and Pioneer Station, two proposed offerings from Orbital Assembly, aim to be the first commercial space hotels upon completion.  If the idea of a space hotel sounds enticing, then mark your calendars for 2025. Orbital Assembly, a company that specializes in designing and constructing space stations, is planning to open luxury accommodations in space by that time. So those of us making grand postpandemic travel plans should start considering the final frontier as a destination. With two space hotels in the works—Voyager Station and a more recently announced Pioneer Station—anyone’s next R&R could take place among the stars. Both space hotels would accommodate more than just intergalactic travelers, but would also be suitable for business, manufacturing, and research. Voyager Station, Orbital Assembly’s first proposed space hotel, was originally designed to accommodate 280 guests, though plans have updated that number to 400. The company has also recently shared des

INTRODUCTORY CONCEPTS ·          Compression Members:  Structural elements that are subjected to axial compressive forces only are called columns . Columns are subjected to axial loads through the centroid. ·          Stress: The stress in the column cross-section can be calculated as                                                                         (2.1) where f is assumed to be uniform over the entire cross-section. ·          This ideal state is never reached. The stress-state will be non-uniform due to: ­           Accidental eccentricity of loading with respect to the centroid ­           Member out-of –straightness (crookedness), or ­           Residual stresses in the member cross-section due to fabrication processes. ·          Accidental eccentricity and member out-of-straightness can cause bending moments in the member. However, these are secondary and are usually ignored. ·          Bending moments cannot be neglected if they are acting on the mem
