Segmented solid-propellent rocket engine fired by United Technology Corp. at Sunnyvale, generating over 200,000 pounds of thrust in 80-second firing. Developed under NASA contract, center section of engine contained over 55,000 pounds of propellant, the largest single piece yet manufactured in the United States. References: 18 .

In what was to have been an acceptance test, the Douglas Aircraft Company static fired the first Saturn S-IV flight stage at Sacramento, Calif. An indication of fire in the engine area forced technicians to shut down the stage after little more than one minute's firing. A week later the acceptance test was repeated, this time without incident, when the vehicle was fired for over seven minutes. (The stage became part of the SA-5 launch vehicle, the first complete Saturn I to fly.) References: 16 .

During tests of the Apollo earth landing system (ELS) at El Centro, Calif., boilerplate (BP) 6A sustained considerable damage in a drop that was to have demonstrated ELS performance during a simulated apex-forward pad abort. Oscillating severely at the time the auxiliary brake parachute was opened, the spacecraft severed two of the electrical lines that were to have released that device. Although the ELS sequence took place as planned, the still-attached brake prevented proper operation of the drogues and full inflation of the mains. As a result, BP-6A landed at a speed of about 50 fps. References: 16 .

The Saturn V's booster, the S-IC stage, made a "perfect" full-duration static firing by burning for the programmed 2.5 minutes at its full 33,360-kilonewton (7.5-million-lbs) thrust in a test conducted at MSFC. The test model demonstrated its steering capability on command from the blockhouse after 100 sec had elapsed; the firing consumed 2.133-million liters (537,000 gallons) of kerosene and liquid oxygen.

Following the decision to implement the Saturn V dry Workshop, LM-2 was the only flight LM article to remain on Earth. Therefore, NASA Hq requested MSC consideration for early disposition of it to the Smithsonian Institution as an artifact of historical interest. Since it was expected that the Smithsonian would exhibit LM-2 as a replica of LM-5, Headquarters also requested that MSC consider refurbishment to provide a more accurate representation of the LM- 5 configuration before its transfer to the Smithsonian.

Mars probe intended to make a soft landing on Mars. Total fueled launch mass of the lander and orbital bus was 3260 kg. It reached Mars on 12 March 1974, separated from the bus, and entered the atmosphere, where a parachute opened, slowing the descent. As the probe descended through the atmosphere it transmitted data for 150 seconds, representing the first data returned from the atmosphere of Mars. Unfortunately, the data were largely unreadable due to a flaw in a computer chip which led to degradation of the system during its journey to Mars. When the retro-rockets fired for landing, contact was lost with the craft. Mars 6 landed at about 24 degrees south, 25 degrees west in the Margaritifer Sinus region of Mars. Bus ended up in a final heliocentric orbit 1.01 x 1.67 AU, 2.2 degree inclination, 567 day period. References: 1 , 2 , 5 , 6 , 67 , 118 , 274 , 296 .
