Space Science and Exploration

Northrop Grumman is a leader in the science and exploration of space. From NASA's Pioneer Program to the James Webb Space Telescope, we've played an important role in the quest to answer compelling questions, from "How did we get here?" to "How do we make the Earth a better place?" for more than 60 years.

Northrop Grumman's Vital Role in Apollo Mission Success

July 20, 1969: A historic day for America. While the world watched, astronaut Neil Armstrong took mankind's first steps on the moon. Years later, as the breathtaking success of NASA's Apollo 11 mission is remembered and celebrated, several heritage companies of today's Northrop Grumman are recognized for the vital roles they played in the achievement.

At its Bethpage, N.Y. facility, Grumman Corporation, now part of Northrop Grumman Aerospace Systems, designed, assembled, integrated and tested the Lunar Module (better known as the LM), the famed Eagle of the Apollo program. Between 1969 and 1972, six Grumman lunar modules carried 12 astronauts to and from the surface of the moon and one – Aquarius – served as a lifeboat for three astronauts during the ill-fated Apollo 13 mission.


Our Mission Systems and Aerospace Systems business sectors were formerly part of TRW, the company that developed the lunar excursion module descent engine (LEMDE) for the Apollo missions. As NASA's official history of the Apollo hardware puts it, the LEMDE "probably was the biggest challenge and the most outstanding technical development" of the entire program. TRW also provided critical software for mission analysis and simulation, guidance and trajectory control, an abort guidance control, and a backup communications system.


Our Mission Systems sector, part of which was the defense and electronics business of Westinghouse, manufactured the camera used to broadcast the now famous images from the lunar surface to earth.

After Armstrong and Buzz Aldrin were on the moon's surface, the camera was placed on a tripod and moved to a location that would capture an overall view of activities. The engineer and the camera itself received television's prestigious Emmy award.

Two other companies that are now part of the Mission Systems sector also made significant contributions to the mission. Dalmo-Victor designed and supplied the S-band 2-Gigahertz high-gain antennas that made possible the transmission of the live images from the moon's surface. Amecom Division of Litton Systems, Inc. produced flush-mounted antennas that transmitted and received all S-band signals during near-Earth operation and served as backup for the high-gain antenna in deep space. Four antennas were mounted on the command module.


Legacy Northrop provided the earth landing system that included the space vehicle recovery parachutes for Apollo 11. In addition, NASA has used the Northrop-built T-38A Talon jet aircraft extensively as trainers for astronauts.

Space Shuttle Solid Rocket Motors


Thiokol Chemical Company, now part of Northrop Grumman Innovation Systems, developed the world's first reusable space propulsion systems for NASA's Space Shuttle program in the late 1970s. The most powerful solid rockets ever flown, two large-diameter RSRMs provided 80% of the lift-off thrust for each of the Shuttle's 135 launches from 1981 to 2011. After boosting the Shuttle to altitudes of nearly 30 miles and speeds of about Mach 5, the reusable solid rocket motors (or RSRMs) separated and returned by parachutes to the ocean approximately 125 miles downrange. Following their recovery and refurbishment, elements of the four-segment boosters were reused up to 12 times on subsequent Shuttle flights. Updated versions of RSRMs are now being produced at our Promontory, Utah facilities for NASA's new heavy-lift rocket, the Space Launch System, which is planned to carry astronauts on deep-space missions in the 2020s and beyond.

James Webb Space Telescope


NASA's James Webb Space Telescope — a technological leap in the mission to explore space — will peer into the past to a time when new stars and developing galaxies were first beginning to form, measuring and capturing images and spectra of galaxies that formed billions of years ago.

The Webb Telescope will also use its superb angular resolution and near-infrared instruments to discover and study planetary systems similar to our own, analyze the molecular composition of extrasolar planets' atmospheres, and directly image Jupiter-size planets orbiting nearby stars.

Before dreams of building the Webb Telescope could be realized, ten technologies that did not exist needed to be created and perfected.

Launch and Deployment

The James Webb Space Telescope Launch and Deployment video shows in-depth what will happen before and after the telescope is launched.

Into the Unknown

Into the Unknown tells the story of the building of NASA's James Webb Space Telescope — a revolutionary observatory, 100 times more powerful and the scientific successor to the Hubble Telescope.
