The University of Arizona opened its new "Mars and Beyond" science exhibit downtown just in time for the city to tear up the streets to install tracks for the Modern Streetcar.

It's still easy, especially on weekends, to get downtown, park and walk over to the space-themed exhibit in the Rialto Block at East Congress Street and 6th Avenue.

UA Science Downtown wants to lure you in this Saturday with special admission prices and added activities on Family Day.

Headed up by graduate students from the UA's Lunar and Planetary Lab, Family Day will include comet-making and meteorite-hunting and the chance to interact with space scientists.

The event runs from 10 a.m. to 6 p.m. Admission is $5 for children; $9 for adults and $7 for students, seniors and the military.
