Question	—	Satellite salvaging: safely de-orbit and retrieve spacecraft or other objects (This question is not about getting scrap metal out of orbit and recycling it: please see the second and third sections of the question text.) Consider an object which was not designed for, or has lost its capacity to perform, atmospheric reentry (for instance: a space station or part of it, a spac... (more)	—	over 6 years ago
Question	—	Anatomically reasonable respiratory system for human-derived merfolk This question considers the respiratory apparatus of an aquatic (or amphibious) species descended from engineered humans. The history of the species provides a relevant constraint. While the science in the setting is soft and the handwavery of fictional genetic engineering might be called upon to pr...

Question	—	Why might it be desirable to engineer aquatic humans? Consider a space opera sort of universe in which there exist communities of water-dwelling humanoids. These ocean people are derived from rootstock humans, descendants of genetically engineered human-variants who pioneered the colonisation of water worlds, or of Earth's oceans. They may live their en... (more)	—	over 6 years ago
Question	—	Is it worth having artificial gravity by propulsion, in orbit or in "free space"? Consider: A spacecraft is travelling between planets. It accelerates at a constant rate for the first half of the trip, and then decelerates on the other half. Throughout the journey, aside from the switch in direction in the middle, the occupants of the ship experience a comfortable consistent gra... (more)	—	over 6 years ago
