A silver (sterling) proof version was marketed by the British Royal Mint (28.27 grams sterling silver), mintage: 218,000. Value: about $25.
How long do you have to study to become an astronaut? A: NASA requires its mission specialists and its commander and pilot astronauts to have bachelor's degrees in biological science, physical science, mathematics or engineering; most people take four years to earn these degrees.
As for how to become an astronaut, we are fortunate as NASA has made the requirements to apply to the NASA astronaut corps available online. If you are from another country, please check with your countryâs space agency. You can follow a similar guide as NASAâs, but be aware that every agency may be different.he first requirement for NASA astronauts is to be a United States citizen. However, if you were not born a natural citizen of the US, donât give up hope! In 1981, Franklin Chang-Diaz became NASAâs first naturalized citizen astronaut. Chang-Diaz was born in Costa Rica and still holds dual citizenship.
