1. Construction begins on the great stone circle at Stonehenge 3000 BCE

   Its smaller bluestones were hauled roughly 240 km from the Preseli Hills in Wales — how Neolithic builders moved them is still debated.

2. Alexander the Great founds the city of Alexandria in Egypt 331 BCE

   It became home to both the Great Library and the Pharos lighthouse, one of the Seven Wonders. Alexander never saw the finished city — he died eight years later.

3. Emperor Constantine dedicates Constantinople as the new Roman capital 330

   Built on the old Greek city of Byzantium, it remained an imperial capital for over a thousand years and is now Istanbul, Turkey's largest city.

   The Apollo guidance computer had less processing power than a modern pocket calculator — and alarms from it nearly aborted the landing.

   She was cloned from a mammary gland cell, so the scientists named her after Dolly Parton.

6. SpaceX launches its Falcon Heavy rocket for the first time 2018

   The test payload was Elon Musk's own red Tesla Roadster, with a spacesuited mannequin named Starman at the wheel — it is still orbiting the Sun.
