Hawaii can expect a pair of bright evening passes by the International Space Station this week, if the clouds cooperate.
There also will be a pair of early morning appearances.
At 8:55 p.m. Wednesday the space station will rise in the southwest, where Jupiter reigns high in the sky. It will angle to the right, passing above the constellation Gemini before blinking out of sight between the Big Dipper and the North Star.
In the southeast, Mars will be near the head of the constellation Scorpius, with Saturn lower and to the left. The bright star Arcturus, Hokule‘a in Hawaiian, will be high in the east.
At 8:02 p.m. Thursday the space station will again rise in the southeast — much brighter this time — and rise to the left of Jupiter. It will pass above Hokule‘a before disappearing above the northeastern horizon. Mars and Saturn will be low in the southeast.
Just before 5 a.m. Saturday, the station will rise in the northwest and angle to the right, passing above the North Star and the constellation Cassiopeia. It will blink out in the southeast at about 5:03 a.m.
A waning gibbous moon will be halfway up the sky in the south-southeast, and Mars and Saturn will be low in the southwest.
On Monday the space station will rise in the northwest at about 4:49 a.m. and angle left, passing high above Mars and Saturn, which are about to set in the southwest. It will blink out in the south at about 4:54 a.m.
The space station is visible after dusk and before dawn when it is illuminated by the sun. It is currently 249 miles high and orbiting at 17,150 mph, or 5 miles per second.
