Miscellaneous Space Notes

Seafood from Asia Raised on Pig Waste, Says News Report---The feces are added to the water to produce an algae bloom," he says, which in turn produces a form of plankton that the fish then eat.[ comment:  This produced a "yuk" reaction on Instapundit, but I think there may be something here that can be used to process waste in space.  A speculation, but interesting.]

British engineers produce amazing 'petrol from air' technology----Tonight Institution of Mechanical Engineers (IMechE) officials admitted that while the described the technology as being “too good to be true but it is true”, it could prove to be a “game-changer” in the battle against climate change.  [comment:  But nothing in the article states the economy of the the device.  How much does it cost to produce how much?  Of course you can produce fuel this way, but that is not the most important question.  The most important question is if it is viable or not.]

Blue Origin Successfully Tests Engine--- Earlier this month, the company successfully fired the thrust chamber assembly for its new 100,000 pound thrust BE-3 liquid oxygen/liquid hydrogen rocket engine. [ comment:  Hydrogen engines are significant for a potential SSTO rocket.]

Mars Facts from Nasa---Escape Velocity
Metric: 18,108 km/h
English: 11,252 mph
Scientific Notation: 5.030 x 103 m/s
By Comparison: Escape velocity of Earth is 25,030 mph.  [ comment:  Speculation in the form of a question:  Could you land on Mars with a balloon?  JP Aerospace wants to get to orbit with a balloon on Earth, but what about deorbiting Mars with a balloon?  Impossible?]
