Three exhibits bring up a soar subject: flight.
Apparently, the clusterfuck known as O’Hare features innovative airport design. In “ORD: Documenting the Definitive Modern Airport” at the Chicago Architecture Foundation, striking photos by Hedrich Blessing and Robert Burley capture the airport from the 1950s to the 1980s, driving you to wax nostalgic over plane delays. Who’d a thunk it? 224 S Michigan Ave, 312-922-3432; 9:30am–5pm through May 1; free.
The Adler Planetarium celebrates the twin Mars rovers’ longevity (five ’bot years is about 500 in human years) by saying Happy Birthday, Spirit and Opportunity. Geek out with 3-D images of Mars and learn about the development of future rovers in the Space Visualization Lab. 1300 S Lake Shore Dr, 312-922-7827; Sun 25, noon–2pm; admission $10, kids ages 3–14 $6
Chicago suburbs seem to breed feminist feats (like Hillary Clinton’s—oh, wait, almost). Likewise, the Elmhurst Historical Museum shows off a few fearless femmes in the exhibit “Heroes of the Sky.” Pre-O’Hare, the now defunct Elmhurst Airport served as a fly-in station for amateur pilot groups such as the all-women Ninety-Nines. Other displays include fliers and innovators who beefed up airplanes into the sophisticated machines we use today. 120 E Park Ave, Elmhurst, 630-833-1457; Tue–Sun 1–5pm; through Mar 15; free.
