At present within the historical past of astronomy, an area program workhorse takes flight.

- NASA’s Area Shuttle Discovery, this system’s third orbiter, skilled important pre-launch setbacks together with thermal defend flaws and a number of aborted launch makes an attempt on account of pc and engine malfunctions.
- Preliminary launch makes an attempt have been delayed or aborted in June and July 1984 on account of recognized technical points necessitating repairs and software program updates.
- Discovery efficiently launched on August 30, 1984, commencing a 27-year operational lifespan.
- Throughout its operational life, Discovery participated in pivotal missions together with Worldwide Area Station building and resupply, Hubble Area Telescope deployment, and Mir Area Station visits, in the end accumulating 149 million miles of flight.
The third member of NASA’s space shuttle program, Discovery had a fraught journey to its launch. First, a take a look at in June of 1984 discovered a flaw within the thermal defend; then a launch scheduled for later the identical month was delayed on account of a pc failure. Try No. 2 was halted only four seconds before lifting off, when the pc registered an issue with one of many engines. As soon as the engine had been changed, a 3rd launch try was scheduled after which scratched on account of a software program downside. Lastly, on Aug. 30, 1984, Discovery blasted off, starting a 27-year-career – it will develop into the most-flown orbiter in NASA’s fleet. Throughout that lengthy lifetime, Discovery took half in building and supplying of the Worldwide Area Station, launched the Hubble Area Telescope, and flew two missions to the Mir Area Station. By the point it was retired after its remaining mission, in 2011, it had flown 149 million miles.
