Hawaii residents can expect impressive evening passes of the International Space Station on Friday and Sunday, weather permitting.
The space station will rise in the northwest just after 8 p.m. Friday and head to the right, piercing the pan of the Little Dipper.
Three minutes later, it will bisect the so-called Summer Triangle, made up of three bright stars: Vega in the constellation Lyra; Deneb in the constellation Cygnus; and Altair in the constellation Aquila. Just before 8:04 p.m., it will pass just under Altair before it blinks out in the eastern sky.
High in the southern sky, Jupiter will shine brightly between a growing gibbous moon and the red star Antares.
On Sunday, the space station will rise in the northwest just before 8 p.m. and angle to the left, passing below the star Arcturus, on Hokule‘a, in the west, and very near the star Spica (Hikianalia) in the west-southwest. It will fly for another two minutes before it disappears below Jupiter.
The moon will be very near Saturn in the southeast.
The space station, 250 miles high and traveling at 17,000 mph, is visible j ust after sunset and just before dawn when it is illuminated by the sun against the darker sky. Aboard are U.S. astronauts Christina Koch, Nick Hague and Drew Morgan, two Russians and an Italian.
