SMS-1 (Synchronous Meteorological Satellite) was the first satellite in the first series of geostationary meteorological satellites. (A geostationary satellite is in an orbit that keeps it above the same part of the Earth all of the time.)

On this day in 1825 – May 20th – American astronomer George Phillips Bond was born in Dorchester, Massachusetts.

He succeeded his father, William Cranch Bond, as director of Harvard College Observatory. And he is considered by many to be the father of astrophotography, his achievements including taking the first photograph of a star (Vega in 1850), and of the double star Alcor and Mizar in Ursa Major in 1857. He also discovered several comets and carried out studies of Saturn and the Orion Nebula.

On this day in 1990 – May 20th – the Hubble Space Telescope sent back its first image, that of several stars captured with its Wide Field/Planetary Camera.

Unfortunately, it was then discovered that there was a flaw in the main mirror which meant fuzzy images for three years until the first shuttle servicing mission. Interestingly, the images were still much better than the ones from ground-based telescopes of the time.

Do you think it was because they were taken outside the Earth's atmosphere?

Angie, fortunately the Hubble mirror problem wasn't taking it outside the atmosphere. I say "fortunately" because just think of the problems for future space telescopes! It was actually a tiny error that occurred when the mirror was polished. NASA's budget didn't stretch to testing the mirror before launch. The backup mirror turned out to be flawless and is now in the National Air and Space Museum in Washington, DC.
