Don't forget cat scans and water purification systems from that link to go along with camera phones and memory foam mattresses.Splendid. Well worth it then....The ISS is the most expensive machine ever constructed with a price tag at around $150bn (£115bn). Nasa’s space shuttle programme, which kicked off in the early 1970s by promising safe and affordable access to space, hoped to cost just a few tens of million dollars per launch. But as the shuttle was thrown in the scrapyard in 2011, the agency estimated the total cost at $209bn — nearly $1.6bn per flight. Splendid we have cameras on our phones, non stick frying pans and memory foam mattresses. Meanwhile Nearly 1/2 of the world's population — more than 3,000,000,000 people — live on less than $2.50 a day. More than 1.3 billion live in extreme poverty — less than $1.25 a day. 1 billion children worldwide are living in poverty. According to UNICEF, 22,000 children die each day due to poverty.
I guess space and space travel is either something that grabs your attention and imagination or it doesn't. I think it's a worthy cause and if we as a species stop asking questions and pushing boundaries we lose something about ourselves. Which is not to say that worldwide poverty isn't a scar on us all. Maybe instead of stopping space travel and investigation we make people and corporations pay their fair share instead of hiding behind complex tax avoidance schemes. Or maybe don't spend billions on nuclear weapons.
