On October 4, 1957 the launch of Sputnik-1 marked the beginning of the Space Age.

Every year since 2004 in the early October IKI hosts annual Space Science Days, dedicated to the date. This is a special event or a series of events about space research and exploration today.

Though the main speakers are usually space scientists, we welcome everyone interested in space and especially high-school, undegraduate, and graduate students, who want to work further in the field.

In 2026 Space Science Days will be held since September 29 to October 3, with the focus on the Road to Space biennial conference.
