This weekend will mark a milestone for an organization that honors men and woman who have reached for the stars.

Four veteran shuttle astronauts are set to be inducted into the Hall of Fame — including the commander of the final space shuttle mission and the first woman in an astronaut class.

John Grunsfeld, Steve Lindsey, Kent Rominger and Rhea Seddon will be honored this weekend at the 25th annual U.S. Astronaut Hall of Fame induction ceremony under Space Shuttle Atlantis.

Lindsey flew on STS-135 Space Shuttle Discovery back in 2011. Seddon was selected by NASA in 1978 as part of the first U.S. astronaut class to include women.

Each inductee has completed multiple missions.

The event takes place at 2 p.m. Saturday, May 30, at the Kennedy Space Center Visitor Complex.

More than 20 space legends will attend.
