today an industrial park, but exists on the site of the former Grand Rapids Airport. A large portion of the north-south runway is used today as the roadway of the Roger B. Chaffee Memorial Boulevard. Roger B. Chaffee Scholarship Fund in Grand Rapids, Michigan, each year in memory of Chaffee honors one student who intends to pursue a career in engineering or the sciences Three adjacent parks in Fullerton, California, are each named for Grissom, Chaffee and White. The parks are located near a former Hughes Aircraft research and development facility. A Hughes subsidiary, Hughes Space and Communications Company, built components for the Apollo program. Two buildings on the campus of Purdue University in West Lafayette, Indiana, are named for Grissom and Chaffee (both Purdue alumni). Grissom Hall houses the School of Industrial Engineering (and was home to the School of Aeronautics and Astronautics before it moved into the new Neil Armstrong Hall of Engineering). Chaffee Hall, constructed in 1965, is the administration complex of Maurice J. Zucrow Laboratories where combustion, propulsion, gas dynamics, and related fields are studied. The Chaffee Hall contains a 72-seat auditorium, offices, and administrative staff. A tree for each astronaut was planted in NASA's Astronaut Memorial Grove at the Johnson Space Center in Houston, Texas, not far from the Saturn V building, along with trees for each astronaut from the Challenger and Columbia disasters. Tours of the space center pause briefly near the grove for a moment of silence, and the trees can be seen from nearby NASA Road 1. Remains of CM-012 The Apollo 1 command module has never been on public display. After the accident, the spacecraft was removed and taken to Kennedy Space Center to facilitate the review board's disassembly in order to investigate the cause of the fire. When the investigation was complete, it was moved to the NASA Langley Research Center in Hampton, Virginia, and placed in a secured storage warehouse. On February 17, 2007, the parts of CM-012 were moved approximately to a newer, environmentally controlled warehouse. Only a few weeks earlier, Gus Grissom's brother Lowell publicly suggested CM-012 be permanently entombed in the concrete remains of Launch Complex 34. On January 27, 2017, the 50th anniversary of the fire, NASA put the hatch from Apollo1 on display at the Saturn V Rocket Center at Kennedy Space Center Visitors Complex. KSC's Visitor Complex also houses memorials that include parts
