ISS and Cygnus supply ship to provide 'space chase' spectacle over Irish skies
A rare 'space chase', involving the International Space Station (ISS) and a re-supply spaceship called Cygnus, will take place on Tuesday evening at precisely 6.34pm.
The ISS will pass our field of view for around one-to-two minutes with the supply ship following shortly after it.
Cygnus will be delivering approximately 3,500 kg of pressurised cargo including supplies and scientific experiments to the ISS.
"It is extremely rare to see a ‘space chase’ in Irish skies, so we are urging everyone in Ireland to go out and watch this amazing spectacle," said Astronomy Ireland’s David Moore.
"The ISS is making space history rather like Columbus did when he set sail for the Americas. ISS is mankind's first outpost in space. It's 10 to 100 times brighter than the brightest star in the sky so it is plainly, indeed spectacularly, visible to the naked eye."
The ISS will be blazing across the sky for the next few weeks with six astronauts aboard.
