The SA-9 (Saturn I Block II), the eighth Saturn I flight, lifted off on February 16, 1965. This was the first Saturn with an operational payload, the Pegasus I meteoroid detection satellite. SA-9 successfully deployed the Pegasus I, NASA's largest unmarned instrumented satellite, into near Earth orbit.

Pegasus-1, meteoroid detection satellite, installed on Saturn I (SA-9 mission) S-IV stage, January 13, 1965. The satellite was used to obtain data on frequency and penetration of the potentially hazardous micrometeoroids in low Earth orbits and to relay the information back to Earth. SA-9 was launched on February 16, 1965 and the Pegasus-1 satellite was the first operational payload for Saturn I.

The successful launch of the Pegasus satellite marked the largest unmarned instrumented satellite in orbit up to 1965.

In this photograph, the Pegasus, meteoroid detection satellite is installed in its specially modified Apollo service module atop the S-IV stage (second stage) of a Saturn I vehicle for the SA-9 mission at Cape Kennedy. Personnel in the service structure moved the boilerplate Apollo command module into place to cap the vehicle. The command and service modules, visible here, were jettisoned into orbit to free the Pegasus for wing deployment. The satellite was used to obtain data on frequency and penetration of the potentially hazardous micrometeoroids in low Earth orbits and to relay the information back to Earth. The SA-9 was launched on February 16, 1965.

NASA’s Pegasus barge, seen off toward the right, prepares to depart from the agency’s Kennedy Space Center in Florida on Aug. 4, 2020, for its trip to NASA’s Michoud Assembly Facility in Louisiana. The Pegasus barge arrived at Kennedy on July 29, delivering the launch vehicle stage adapter (LVSA) for the agency’s Space Launch System (SLS) rocket – the most powerful rocket NASA has ever built, providing the muscle necessary to get to the Moon and eventually to Mars. The LVSA – now undergoing processing inside the Vehicle Assembly Building – will connect the core stage of the rocket to the upper stage. The next time the Pegasus barge returns to Kennedy, it will be carrying the SLS core stage – the final piece of the rocket that needs to be delivered ahead of the Artemis I launch.

Activities at Green Mountain Tracking Station, Alabama, during lift-off of the Saturn I, SA-9 mission, showing the overall view of instrument panels used in tracking the Pegasus, meteoroid-detection satellite. The satellite was used to obtain data on frequency and penetration of the potentially hazardous micrometeoroids in low Earth orbits and to relay the information back to Earth.

Fairchild technicians check out the extended Pegasus meteoroid detection surface. The Pegasus was developed by Fairchild Stratos Corporation, Hagerstown, Maryland, for NASA through the Marshall Space Flight Center. Three Pegasus satellites were flown aboard Saturn I SA-8, SA-9, and SA-10 missions. After being placed into orbit around the Earth, the satellite unfolded a series of giant panels to form a pair of wings measuring 96 feet across. The purpose of the satellite was to electronically record the size and frequency of particles in space, and compare the performance of protected and unprotected solar cells as important new preliminaries to a marned flight to the Moon.

These images show NASA’s Pegasus barge at NASA’s Michoud Assembly Facility in New Orleans as it transported the Artemis I launch vehicle stage adapter (LVSA) of the agency’s Space Launch System rocket to NASA’s Kennedy Space Center in Florida. Leaving with the adapter from NASA’s Marshall Space Flight Center in Huntsville, Alabama, Pegasus made a brief stop at Michoud to offload supplies and equipment before continuing its to Kennedy. The LVSA connects the deep space rocket’s 212-foot-tall core stage to the rocket’s upper stage and will be used for Artemis I, the first in a series of increasingly complex missions to the Moon through NASA’s Artemis program. Once at Kennedy, the LVSA will undergo Artemis I launch preparations. Only the SLS core stage, currently in final testing at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, remains to be shipped to Kennedy on Pegasus. The core stage is produced at Michoud. Together with four RS-25 engines, the rocket’s massive 212-foot-tall core stage — the largest stage NASA has ever built — and its twin solid rocket boosters produce 8.8 million pounds of thrust to send NASA’s Orion spacecraft, astronauts and supplies beyond Earth’s orbit to the Moon. Offering more payload mass, volume capacity and energy to speed missions through space, the SLS rocket, along with NASA’s Gateway in lunar orbit, the Human Landing System and Orion, is part of NASA’s backbone for deep space exploration and the Artemis lunar program. No other rocket is capable of carrying astronauts in Orion around the Moon in a single mission.

These images show how teams at NASA’s Michoud Assembly Facility in New Orleans moved the core stage, complete with all four RS-25 engines, for NASA’s Space Launch System (SLS) rocket to Building 110 for final shipping preparations on Jan. 1. The SLS core stage includes state-of-the-art avionics, propulsion systems and two colossal propellant tanks that collectively hold 733,000 gallons of liquid oxygen and liquid hydrogen to power its four RS-25 engines. The completed stage, which will provide more than 2 million pounds of thrust to help power the first Artemis mission to the Moon, will be shipped via the agency’s Pegasus barge from Michoud to NASA’s Stennis Space Center near Bay St. Louis, Mississippi, later this month. Once at Stennis, the Artemis rocket stage will be loaded into the B-2 Test Stand for the core stage Green Run test series. The comprehensive test campaign will progressively bring the entire core stage, including its avionics and engines, to life for the first time to verify the stage is fit for flight ahead of the launch of Artemis I.

The Saturn I S-I stages for the SA-8 and SA-10 mission in final assembly phase in a manufacturing building at the Michoud Assembly Facility in New Orleans, Louisiana. The SA-8 mission was launched on May 25, 1965 with the first industry-built booster, and deployed the Pegasus II Micrometeoroid Detection satellite. The SA-10 mission was the last Saturn I mission, launched on July 30, 1965, and carried the Pegasus III Meteoroid Detection satellite.

First night time launching of a Saturn I launch vehicle took place at 2:35 a.m., May 25, 1965, with the launch of the second Pegasus meteoroid detection satellite from Complex 37, Cape Kennedy, Florida.

In this photo, Dr. von Braun anxiously awaits the launch of the Saturn I vehicle (SA-8) in the Launch Complex Control Center at the Kennedy Space Center in Florida on May 25, 1965. The SA-8 mission made the first night launch and deployed the Pegasus II micro meteoroid detection satellite.

The first core stage of NASA’s Space Launch System (SLS) rocket, loaded onto the agency’s Pegasus barge, departs Stennis Space Center near Bay St. Louis, Mississippi, headed to Kennedy Space Center in Florida. The departure of the core stage in mid-April 2021 followed completion of a Green Run test series of the stage systems in preparation for its launch on the Artemis I mission. The Green Run series concluded with a March 18 hot fire of the stage’s four RS-25 engines on the B-2 Test Stand at Stennis, just as during an actual launch. Following refurbishment work, the stage was removed from the B-2 stand and loaded onto the Pegasus barge for transport. Once at Kennedy, the will be integrated with the rest of SLS rocket and prepared for the launch of the Artemis I mission to the Moon. Photo Credit: NASA

The move team loads the launch vehicle stage adapter, part of the agency’s new Space Launch System (SLS) rocket, on NASA’s Pegasus barge at NASA’s Marshall Space Flight Center in Huntsville, Alabama, July 17. The launch vehicle stage adapter, which connects the rocket’s 212-foot-tall core stage to the rocket’s upper stage, is being shipped to NASA’s Kennedy Space Center in Florida for Artemis I launch preparations. This is the final piece of Artemis I SLS rocket hardware built at Marshall to be delivered to Kennedy. Only the SLS core stage, currently in final testing at Stennis Space Center near Bay St. Louis, Mississippi, remains to be shipped to Kennedy on Pegasus. NASA is working to land the first woman and the next man on the Moon by 2024. SLS, along with Orion, the human landing system, and the Gateway in orbit around the Moon are NASA’s backbone for a new generation of deep space exploration.
