AS-202
the 25th of August 1966 marked the launch of AS-202 from Pad 34. This mission served as the third test flight for the Saturn IB rocket. Engineers needed to push the vehicle higher than previous attempts. The flight duration was designed to be twice as long as earlier tests. A key goal involved testing the command and service module CSM-011. This spacecraft featured a new guidance and navigation system. It also included fuel cell electrical systems never used before. The heat shield faced extreme conditions during reentry. It absorbed energy equivalent to powering Los Angeles for over one minute in 1966. The capsule lacked crew couches found on later versions. Some displays were missing compared to future missions. These omissions did not stop the engineering team from validating critical systems.
The first stage burned for just under two and a half minutes. It lifted the rocket downrange from the launch pad. The second stage then fired for seven and a half minutes. This burn placed the spacecraft into a ballistic trajectory. Separation occurred at an altitude of 185 kilometers. The command module separated from the S-IVB second stage shortly after. Four burns of the service propulsion system followed. The first burn lasted three minutes and 35 seconds. It raised the apogee to 274 kilometers. The second burn happened 25 minutes later and lasted one minute 28 seconds. Two additional three-second burns tested rapid restart capabilities. The module entered the atmosphere at 24,000 miles per hour. A skip reentry maneuver sent it back up to 110 kilometers. Speed dropped by 18,000 miles per hour during this phase. Main parachutes deployed at 10,000 feet. Splashdown occurred 19 nautical miles from the target site southeast of Wake Island.
AS-202 provided rare close-up footage of Saturn staging. Ejectable cameras were mounted on each launch vehicle. This technology originated with the earlier Saturn I program. One camera sat on the S-IB first stage looking forward. It captured the S-IVB upper stage pulling away. The footage showed the single J-2 engine firing. Three ullage motors fired as the upper stage detached. Later S-IVB iterations used only two such motors. The video became stock footage for many documentaries. Filmmakers often use it to illustrate crewed flight staging. Some productions mistakenly attribute the clip to Apollo 11. The footage remains a vital historical record despite its uncrewed origin. It shows the mechanical separation clearly without human interference.
The spacecraft entered the atmosphere at high velocity. It performed a skip reentry before descending again. Main parachutes opened at 10,000 feet altitude. The capsule splashed down in the Pacific Ocean. Recovery forces needed eight hours and 30 minutes to reach the module. The USS Hornet aircraft carrier traveled approximately 45 nautical miles southeast of Wake Island. The ship arrived to retrieve CSM-011 from the water. This retrieval process proved successful after the long wait. The mission validated that the Block I spacecraft could carry men into orbit. Engineers judged the Saturn IB ready for the next step. AS-204 was scheduled to follow this test flight immediately. The recovery team secured the capsule for transport back to land.
Expo 67 in Montreal hosted the US Pavilion display. The capsule sat there for public viewing during the world fair. Later years saw the artifact move to California. It now rests aboard the USS Hornet Museum in Alameda. The ship serves as a floating museum open to the public. Visitors can view the command module inside the vessel. This location preserves the history of early Apollo testing. The journey from Expo 67 to Alameda spans decades. The capsule remains a central exhibit for space enthusiasts. Its presence on the ship honors the engineering achievements of the 1960s. No other surviving Block I capsule exists in such a setting.

Common questions
When did the AS-202 launch take place?
The AS-202 launch took place on the 25th of August 1966 from Pad 34. This mission served as the third test flight for the Saturn IB rocket.
What was the purpose of the AS-202 spacecraft CSM-011?
AS-202 tested the command and service module CSM-011 with a new guidance and navigation system. The spacecraft also included fuel cell electrical systems never used before in previous attempts.
Where did the AS-202 capsule splashdown occur?
The AS-202 capsule splashed down 19 nautical miles southeast of Wake Island after entering the atmosphere at 24,000 miles per hour. Recovery forces needed eight hours and 30 minutes to reach the module near the USS Hornet aircraft carrier.
How long did the first stage burn last during the AS-202 mission?
The first stage burned for just under two and a half minutes to lift the rocket downrange from the launch pad. The second stage then fired for seven and a half minutes to place the spacecraft into a ballistic trajectory.
Where is the AS-202 capsule currently located?
The AS-202 capsule now rests aboard the USS Hornet Museum in Alameda California. It previously sat at Expo 67 in Montreal before moving to its current location as a central exhibit for space enthusiasts.
