Launch Area 3

NASA’s Wallops Flight Facility in Virginia played a key role in early American space exploration. One of its most important sites was Launch Area 3 (LA-3), which supported the launch of SCOUT rockets between 1960 and 1985. This launch complex helped make low-cost, solid-fueled space missions a reality, contributing significantly to satellite deployment and scientific research.

Launch Area 3: The Heart of SCOUT Missions

Launch Area 3 consisted of two primary launch pads:

• LA-3 (Mk.I): Operational from April 18, 1960, to March 7, 1970, supporting 22 launches, including SCOUT and other vehicles like Nike-Apache and Nike-Iroquois.

• LA-3A (Mk.II): In use from July 20, 1964, to December 13, 1985, facilitating 23 launches, including advanced versions of the SCOUT rocket series.

SCOUT: A Revolutionary Solid-Fuel Rocket

The SCOUT rocket (Solid Controlled Orbital Utility Test system) was designed in the late 1950s and early 1960s to provide a cost-efficient, reliable option for launching small satellites. Developed by NASA and the U.S. Air Force, SCOUT set the standard as the first all-solid-fuel rocket to successfully reach orbit.

SCOUT’s Four-Stage System

1. First Stage – Algol: Delivered 130,000 pounds of thrust, propelling the rocket off the ground.

2. Second Stage – Castor: Fired for 41 seconds, boosting the vehicle higher into the atmosphere.

3. Third Stage – Antares: Provided 18,000 pounds of thrust, adjusting the rocket’s trajectory.

4. Fourth Stage – Altair: Gave a final 6,000-pound thrust over 34 seconds, inserting the payload into orbit.

Notable SCOUT Launches from Wallops Island

Many historic space missions launched from Launch Area 3 at Wallops, proving the SCOUT rocket’s versatility and reliability:

• Explorer 9 (February 16, 1961): First successful SCOUT orbital launch; deployed a 30-inch Mylar sphere to measure atmospheric density.

• San Marco 1 (December 15, 1964): Italy’s first satellite, launched through international collaboration.

• Explorer 37 (SOLRAD 8, July 22, 1968): Studied solar radiation and the ionosphere.

• Orbiting Frog Otolith (OFO)

• SolRad 10

• SAS-3 (May 7, 1975): Conducted X-ray astronomy, identifying black holes and neutron stars.

• Magsat (October 30, 1979): First dedicated satellite for mapping Earth’s magnetic field.

• Transit-O 31 (December 13, 1963): Helped develop the Transit navigation system, a forerunner of modern GPS.

• Scout Transport Mission

Wallops: An Unsung Hero of Space Exploration

Between 1960 and 1985, Wallops hosted 41 SCOUT launches, many from Launch Area 3, where early versions used the MKI launcher, later transitioning to the MKII launcher. Though SCOUT was retired in 1994, its legacy continues through modern solid-fueled launch vehicles like Pegasus and Minotaur.

Why SCOUT Matters Today

SCOUT wasn’t just about launching satellites—it laid the foundation for modern space technology. Its innovations influenced Starlink, GPS, and other satellite-based systems we rely on daily. Standing on the shores of Wallops Island, watching rockets launch, was witnessing the early roots of today’s advanced space exploration.
