The Conversation has a story about five key findings from 15 years of the International Space Station:
1. The fragility of the human body — there is considerable loss of strength and bone mass without intervention. Mitigating this is key to making it possible to have manned trips to mars.
2. Interplanetary contamination — spores of Bacillus subtilis were exposed to space upon the ISS (but shielded from solar UV radiation). "The space vacuum and temperature extremes alone were not enough to kill them off."
3. Growing crystals for medicine — "Crystals in a microgravity environment may be grown to much larger sizes than on Earth, enabling easier analysis of their micro-structure. Protein crystals grown on the ISS are being used in the development of new drugs for diseases such as muscular dystrophy and cancer."
4. Cosmic rays and dark matter — early results from the Alpha Magnetic Spectrometer (AMS) support the theory that a halo of dark matter surrounds the Milky Way.
5. Efficient combustion — flames burn more efficiently in space with much less soot produced. Understanding this may lead to more efficient combustion in vehicles.

Training, budgeting, engineering, manufacturing, quality control, mission control, launches, communications, resupply, dealing with emergencies. And providing career paths for aeronautical engineers and astronauts in the USA.
Skill within any demanding skill is use it or lose it - now we can barely remember how we got to the moon. Continued practice is vital, and that costs lots of money.
