Glenn Research Center

Glenn Research Center

NASA John H. Glenn Research Center at Lewis Field is one of ten major NASA facilities. It is located in the cities of Brook Park and Cleveland, between Cleveland Hopkins International Airport and the Rocky River Reservation of Cleveland Metroparks. The center also has a smaller facility in Sandusky, Ohio.

The main job of Glenn Research Center is to create new science and technology for use in air travel and space exploration.

In 2010, the NASA Visitors Center that used to be on the Glenn Research Center property moved to the Great Lakes Science Center in the North Coast Harbor area of downtown Cleveland.

History

The Glenn Research Center was created in 1942 as part of the National Advisory Committee for Aeronautics. Later, it became a lab for airplane engine research under the National Aeronautics and Space Administration.

It started as the Aircraft Engine Research Laboratory. Over the years, it was renamed several times: to the Flight Propulsion Research Laboratory in 1947, the Lewis Flight Propulsion Laboratory in 1948 (after George W. Lewis), and the NASA Lewis Research Center in 1958. In 1999, it was named the NASA John H. Glenn Research Center at Lewis Field to honor John Glenn, the first American to orbit the Earth. By 1951, scientists there were already studying how rocket engines work with liquid fuel liquid rocket.

Facilities

Neil A. Armstrong Test Facility

The NASA John H. Glenn Research Center at the Neil A. Armstrong Test Facility, near Sandusky in southern Erie County, Ohio, is a big testing site. It is about 50 miles from the main center and is used for large tests that are not safe to do at the main location.

As of 2025, the facility includes five main areas for testing:

• Space Environments Complex
• In-Space Propulsion Facility
• Combined Effects Chamber
• Hypersonic Tunnel Facility
• NASA Electric Aircraft Testbed

In 2019, Ohio’s senators Rob Portman and Sherrod Brown suggested naming the site after Neil Armstrong. This change became official law on December 30, 2020.

The B-2 Spacecraft Propulsion Research Facility is special because it can test large rocket engines and parts under conditions that copy high altitudes. It has the world’s largest vacuum chamber for space tests.

Icing Research Tunnel

The Icing Research Tunnel is a wind tunnel that can copy conditions where ice forms in the air. It helps scientists test how ice affects airplane wings and bodies, and how to prevent ice build-up.

Zero Gravity Research Facility

Main article: Zero Gravity Research Facility

The Zero Gravity Research Facility uses a tall vacuum chamber to let experiment packages fall, helping scientists study how things behave without gravity.

The facility has a big concrete shaft, 28 feet wide, that goes 510 feet deep. Inside is an aluminum vacuum chamber, 20 feet wide and 470 feet tall. Before use, the air pressure inside is lowered to a very low level.

There is also a smaller tower where things can fall for 2.2 seconds, used for special educational programs like Dropping in a Microgravity Environment and What if No Gravity.

This facility became a National Historic Landmark in 1985 and has been the world’s largest place for zero-gravity research since 2003.

Developments

NASA Glenn works on new ideas for airplanes and space travel. They study how to make jet engines use less energy, create less pollution, and make less noise. You can see their noise-reducing designs on many airplane engines today, like those on the Boeing 787 Dreamliner.

Glenn Research Center also helped create important technologies for space. These include the liquid hydrogen rocket engine, which was key to the Apollo Moon landings, and a special engine called the Centaur upper-stage rocket. They also made a very efficient engine for space called the gridded ion thruster, used on the NASA probe Deep Space 1. Glenn also provided the power system for the International Space Station and helped design an adapter for a new version of the Space Launch System (SLS).

Contributions

The Glenn Research Center studies important topics like air-breathing engines, communication technology, space engines, and storing and moving special fluids. They also work on creating power and energy solutions and study materials that can survive in extreme conditions.

The center has special programs for students and teachers. High school and college students, as well as teachers, can join internships to learn about science and technology with NASA experts. There is also a yearly contest called the Dropping In Microgravity Environment where high school teams design experiments to test in a special tower.

Future

After 2004, NASA started to focus more on space exploration. Some people thought centers like Glenn might get fewer resources. But in 2006, Glenn got to manage the service module for the Crew Exploration Vehicle. This brought more money and jobs to the center and helped secure its future.

In 2010, there was some uncertainty when President Obama and Congress changed NASA's plans for space flights. But in 2015, NASA's budget increased funding for projects that Glenn works on, like aeronautics research, planetary science, and space technology. This also helped the center.

NASA Glenn Visitor Center

In September 2009, the Glenn Research Center closed its Visitor Center. They moved many displays to the Great Lakes Science Center. This change helped save money and made it easier for more people to visit. The displays are now at a busier science center in Cleveland.

The Glenn Research Center still offers public tours of its research facilities. These tours happen on the first Saturday of each month, but you need to reserve a spot ahead of time.
