Due to a special Joint Meeting of Congress taking place in the Capitol on Wednesday, April 29, the U.S. Capitol will be closed to tours until approximately 12:30 p.m. on that day. The Capitol Visitor Center will remain open throughout the day, 8:30 a.m. to 4:30 p.m., and guided tours of the Capitol Visitor Center will be available while the Capitol is closed.
Space exploration affords numerous benefits, but there are inherent risks. On January 28, 1986, the space shuttle Challenger exploded shortly after liftoff, killing all seven crew members. This was neither the first nor the last such tragedy. After a congressional investigation of the Challenger disaster, the National Aeronautics and Space Administration (NASA) changed its procedures and the U.S. reaffirmed its commitment to space exploration.
