A series of drop tests into the Hydro Impact Basin at the Landing and Impact Research Facility at NASA’s Langley Research Center in Hampton, Virginia helped SpaceX’s Crew Dragon capsule prepare to safely land astronauts. A mock-up of the capsule with two instrumented crash test devices seated inside was tested in March 2019, representing how the capsule may impact the water during splashdown with different wind and parachute dynamics. Data collected helps understand pressures on the capsule and how those forces affect the spacecraft and occupants. Crew Dragon will carry NASA astronauts Bob Behnken and Doug Hurley to the International Space Station in the Demo-2 mission, the final SpaceX flight test for NASA’s Commercial Crew Program and the first flight of astronauts to orbit from U.S. soil since the space shuttle’s retirement in 2011.

Assembling the Little Joe capsules. The capsules were manufactured in-house by Langley technicians. Three capsules are shown here in various stages of assembly. The escape tower and rocket motors shown on the completed capsule would be removed before shipping and finally assembly for launching at Wallops Island. Joseph Shortal wrote (vol. 3, p. 32): Design of the Little Joe capsules began at Langley before McDonnell started on the design of the Mercury capsule and was, therefore, a separate design. Although it was not designed to carry a man, it did have to carry a monkey. It had to meet the weight and center of gravity requirements of Mercury and withstand the same aerodynamic loads during the exit trajectory. Although in comparison with the overall Mercury Project, Little Joe was a simple undertaking, the fact that an attempt was made to condense a normal two-year project into a 6-month one with in house labor turned it into a major undertaking for Langley. Project Mercury: Little Joe: Boilerplate Mercury spacecraft undergo fabrication at the shops of the Langley Research Center. They will launched atop Little Joe rockets to test the spacecraft recovery systems. -- Published in Joseph A.

Technicians prepare a full-scale capsule which would be used for the first rocket-launching on March 11, 1959. The purpose of the test would be to simulate a ground-level or beach abort. Joseph Shortal wrote (vol. 3, p. 27): It was a test of the ability of the escape system to rescue the astronaut in case of a malfunction of the launch vehicle prior to flight. This test was carried out by PARD under the direction of W.S. Blanchard, Jr., and was part of the program designated F57 at PARD. For these tests capsule shape C was used. -- Published in Joseph A.

The Mercury capsule and escape tower are being lowered onto the Little Joe booster for launch on August 21, 1959. Joseph Shortal described this as follows (vol. 3, p. 33): The Little Joe booster was assembled at Wallops on its special launcher in a vertical attitude. It is shown in the on the left with the work platform in place. The launcher was located on a special concrete slab in Launching Area 1. The capsule was lowered onto the booster by crane.... After the assembly was completed, the scaffolding was disassembled and the launcher pitched over to its normal launch angle of 80 degrees.... Little Joe had a diameter of 80 inches and an overall length, including the capsule and escape tower of 48 feet. The total weight at launch was about 43,000 pounds. The overall span of the stabilizing fins was 21.3 feet. Although in comparison with the overall Mercury Project, Little Joe was a simple undertaking, the fact that an attempt was made to condense a normal two-year project into a 6-month one with in house labor turned it into a major undertaking for Langley. -- Published in Joseph A.

A mechanic at the National Aeronautics and Space Administration (NASA) Lewis Research Center prepares the inverted base of a Mercury capsule for a test of its posigrade retrorockets inside the Altitude Wind Tunnel. In October 1959 NASA’s Space Task Group allocated several Project Mercury assignments to Lewis. The Altitude Wind Tunnel was modified to test the Atlas separation system, study the escape tower rocket plume, train astronauts to bring a spinning capsule under control, and calibrate the capsule’s retrorockets. The turning vanes, makeup air pipes, and cooling coils were removed from the wide western end of the tunnel to create a 51-foot diameter test chamber. The Mercury capsule had a six-rocket retro-package affixed to the bottom of the capsule. Three of these were posigrade rockets used to separate the capsule from the booster and three were retrograde rockets used to slow the capsule for reentry into the earth’s atmosphere. Performance of the retrorockets was vital since there was no backup system. Qualification tests of the retrorockets began in April 1960 on a retrograde thrust stand inside the southwest corner of the Altitude Wind Tunnel. These studies showed that a previous issue concerning the delayed ignition of the propellant had been resolved. Follow-up test runs verified reliability of the igniter’s attachment to the propellant. In addition, the capsule’s retrorockets were calibrated so they would not alter the capsule’s attitude when fired.
