After 30 years, and 135 missions, t' storied career for NASA's shuttles is about t' end. Well, blow me down! T' programme began as an ambitious way t' serve NASA's needs in space after t' moon landings. Begad! A shuttle vehicle served military needs, commercial sector requirements, arrr, as well as NASA's missions in space. Avast, me proud beauty!

Without t' shuttle, thar would be no Hubble space spyglass for example, and some important early scientific experiments were conducted on board and in t' payload bay. Arrr! Commander-STS 2 Joe Engle said, "It's a great tool that we've had t' privilege o' usin' in t' space programme for so many years. Avast, me proud beauty! I think...

Despite continued efforts at improvin' crew safety and reliability, two shuttles, Challenger and Columbia, and their crews, were lost durin' t' 30 year history. Arrr! Both were on scientific research missions when disaster struck. But t' tragedies brought with them renewed public support for space exploration. Begad! When NASA set out t' build a space station with 16 international partners ...
