The McAuliffe-Shepard Discovery Center is a science museum located in Concord, New Hampshire, United States, next door to the NHTI campus.

The museum is dedicated to Christa McAuliffe, the Concord High School social studies teacher selected by NASA out of over 11,000 applicants to be the first teacher in space, and Alan Shepard, the Derry, New Hampshire, native and Navy test pilot who became the first American in space and one of only twelve human beings to walk on the Moon.

The 45,000-square-foot (4,200 m2) museum offers 20,000 square feet (1,900 m2) of interactive science and engineering exhibits, outdoor exhibits including a full-sized replica of a Mercury-Redstone rocket, a full-dome digital planetarium, an observatory, science store, portable digital planetarium and a full complement of on- and off-site educational programs.

The State of New Hampshire retained ownership of the facility and grounds, but engaged in a long-term lease with the new nonprofit operator, the McAuliffe-Shepard Discovery Center Corporation.
