On this day in 1968 - May 17th - the first ESRO satellite was successfully launched.
The European Space Research Organisation (ESRO) was a precursor to the European Space Agency (ESA). ESRO-2B was the first mission controlled by teams at the European Space Operations Centre in Darmstadt, Germany. It was mainly intended to study X-ray and particle emissions from the Sun.
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, they then discovered 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.
On this day in 1961 - May 25th - President John F. Kennedy challenged the USA to "commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth."
On this day in 1983 - May 26th - ESA's X-ray observatory, Exosat, was launched.
Exosat was the first ESA mission to study the Universe at X-ray wavelengths, and one of the first unmanned satellites to feature an onboard computer. The spacecraft was operational from May 1983 to April 1986.
