Welcome to the University of Texas Skywatchers Report for Monday September 29th through Sunday October 5th.
The moon is at first quarter on Wednesday the 1st, so we'll start the week with a waxing crescent moon and finish with a waxing gibbous moon.
Three planets line up in the southwestern skies at sunset this week. Mercury is low in the west-southwest and is setting less than an hour after the sun. Saturn is a little higher and to the left of Mercury and is setting at 9:20 p.m. at midweek. Mars is the highest of the three and is setting at 10:30 p.m. Mars is still near its stellar rival Antares, but it slowly moving away each night.
In the morning skies, Jupiter is rising at 3:20 a.m., while Venus is now up just 30 minutes before the sun.
In space anniversaries this week, Sunday October 5th marks the 30th anniversary of the launch of the Space Shuttle Challenger with a crew that included astronauts Sally Ride and Kathy Sullivan, making it the first spaceflight to carry two women into space at the same time. A few days later, Sullivan would become the first American woman to perform a spacewalk. She was beat out of becoming the first woman to perform a spacewalk by a few months by cosmonaut Svetlana Savitskaya.
