International Space Station (ISS)

If you look up this evening, Ireland’s clear skies will offer a prime chance to spot the International Space Station (ISS) as it zooms overhead.

The space laboratory will is making two visible passes across the country: the first occurred at 7:41 pm, high in the southern sky during twilight, and again at 9:17 pm, lower in the southwest.

The ISS orbits Earth roughly every 90 minutes at a speed of 28,000 km/h. It serves as a hub for scientific research in microgravity, hosting experiments in fields ranging from biology to materials science.

Currently on board are astronauts from NASA, ESA, and other partner agencies, working together on a variety of missions.

For anyone wanting to catch a glimpse tonight, remember that binoculars aren’t necessary as the ISS shines brightly and can be seen with the naked eye under clear skies.
