Marshall Space Flight Center ABSTRACT I 1o 15 Mission) was launched at 9:34:OD Eastern 1 July 26, 1971, from Kennedy Space Center, Complex 39, Pad A. "The vehicle lifted off on a launch azisrrth of 90 degrees east of north and rolled to a flight azimuth of 80.088 degrees east of north. The launch vehicle successfully placed the manned space- craft in the planned translunar coast mode. The S-IVB/IU impacted the lunar surface within the planned target area. This was the first Apollo Mission to employ the lunar Roving Vehicle (LRV) during Extravehicular Activity (EVA). The performance of the LRV was satisfactory and resulted in extended EVA, and greatly increased the crews lunar exploration capabilities. All Mandatory and Desirable Objectives of this mission for the launch vehicle were accomplished except the precise determination of the lunar impact point. It is expected that this will be accomplished at a later date. No failures, anomalies, or deviations occurred that seriously affected the mission.

    A PUBLICATION OF THE LUNAR SECTION OF THE A.L.P.O. EDITED BY: Wayne Bailey [email protected] 17 Autumn Lane, Sewell, NJ 08080 RECENT BACK ISSUES: http://moon.scopesandscapes.com/tlo_back.html FEATURE OF THE MONTH – JANUARY 2019 CARDANUS & KRAFFT Sketch and text by Robert H. Hays, Jr. - Worth, Illinois, USA September 24, 2018 04:40-05:04 UT, 15 cm refl, 170x, seeing 7/10, transparence 6/6. I drew these craters and vicinity on the night of Sept. 23/24, 2018. The moon was about 22 hours before full. This area is in far western Oceanus Procellarum, and was favorably placed for observation that night. Cardanus is the southern one of this pair and is of moderate depth. Krafft to the north is practically identical in size, and is perhaps slightly deeper. Neither crater has a central peak. Several small craters are near and within Krafft. The crater just outside the southeast rim of Krafft is Krafft E, and Krafft C is nearby within Krafft. The small pit to the west is Krafft K, and Krafft D is between Krafft and Cardanus. Krafft C, D and E are similar sized, but K is smaller than these. A triangular-shaped swelling protrudes from the north side of Krafft. The tiny pit, even smaller than Krafft K, east of Cardanus is Cardanus E. There is a dusky area along the southwest side of Cardanus. Two short dark strips in this area may be part of the broken ring Cardanus R as shown on the. Lunar Quadrant map.

  • Saturn V Data and Launch History Resized
    Saturn V 50th Anniversary Commemorative Evening, November 8, 1967. AS-501 / Apollo 4, Pad 39A, KSC, FL. The Saturn V Launch Vehicle With a capacity to boost a payload of 260,000 lb. into low Earth orbit, or a 100,000 lb. payload into a lunar trajectory, the Saturn V remains the most powerful launch vehicle yet to leave the Earth's atmosphere. It was capable of placing in orbit a payload more than four times heavier than the future Space Shuttle could lift, and was six times more powerful than the next largest expendable rocket of its day. The Saturn V was designed by NASA engineers at the Marshall Space Flight Center, (MSFC), in Huntsville, AL, under the direction of Dr. Wernher von Braun. Development began in January, 1962. A total of fifteen vehicles were produced. Thirteen flew missions. Characteristics Overall length: 281 ft. (booster), 363 ft. (with spacecraft). Maximum diameter: 33.0 ft. Weight at liftoff: 6,423,000 lbs. Trans-lunar payload capability approximately 107,350 lbs. Earth orbit payload capability, (two stage configuration); 212,000 lbs. Stages First Stage, (S-IC); Contractor: Boeing Assembled: New Orleans, LA . Length: 138 ft. Diameter: 33 ft. Weight: 5,022,674 lbs. fueled / 288,750 lbs. dry. Engines: F-1 (x5) Designed and manufactured by Rocketdyne, Canoga Park, CA. Propellants: LOX (Liquid Oxygen) / RP-1 (Kerosene.) Thrust: 7,610,000 lbs. During the production run, the F-1 was redesigned and up-rated in preparation for the later "J Series" of extended lunar missions. These missions carried heavier payloads. With up-rated engines, the S-IC produced 7,724,000 lbs.

Marshall Space Flight Center Huntsville , Alabama ABSTRACT A Liquid Hydrogen Orbital Experiment is defined, using Saturn IB iaunch vehicle SA-203, which will demonstrate the adequacy of the S-IVB/V continuous vent and propellant settling system prior to a Saturn V launch. The state -of-the -art knowledge of cryogenic propellant behaviour under weightless environment will be significantly advanced by this observation of transient effects on liquid hydrogen through two television cameras mounted on the manhole cover of the S-IVB stage LH2 tank. The experiment justification, objectives, and S-IVB stage instrumentation are presented in detail. The liquid hydrogen experiment was proposed and defined by the Propulsion Division of Propulsion and Vehicle Engineering Laboratory. This report was compiled for R&D Operations with the assistance of Aero -A str odynamic s Labor a tory, Astfionic s Labor ator y, and Quality and Reliability Assurance Laboratory and complements NASA TM X-53 159, "Saturn IB Liquid Hydrogen Experiment Preliminary Lau Design Definition.

  • 1 the Terminal
    2-29 Two eervice propulsion system firings were required for rendezvous. The first firing, a corrective combination maneuver, was necessary to achieve the proper phase and altitude offset so that the second firing would result in an orbit coelliptic with that of the S-IW. The two firings achieved the desired conditions for rendezvous terminal phase initiation. The terminal phase initiation maneuver was performed with an onbaard computer solution based on optical track- t ing of the s-IVB stage with the sextant. A small midcourse correction was then made, followed by braking and final closure to within 70 feet of the S-IVB. Stationkeeping was performed for approximately 20 minutes, after which a 2-foot-per-second service module reaction control system posigrade maneuver removed the spacecraft from the vicinity of the S-Iw stage. The aext 24-hour period was devoted to a sextant calibration test, a rendezvous navigation test, an attitude con- 1 trol test, and a primsry evaporator test. Tbe crew used the sextant to track the S-IVB visually to distances of as uuch as 320 miles. The service propulsion system was fired six additional times during the mission. The third firing was a 9.1-second maneuver controlled by the stabilization and control system. The maneu- ver was performed to increase the backup deorblt capability of the service module reaction con- trol system. The fourth firing was performed to evaluate the minimum-Impulse capability of the service propulsion engine. The fifth firing was performed to position the spacecraft for an op- tinum deorbit maneuver at the end of the planned orbital phase.

    Merguerian, Charles, 1989b, Apollo 15: in F. N. Magill, editor, Magill's Survey of Science, Space Exploration Series, Salem Press, Inc., Pasadena, California, p. 104-109. APOLLO 15 Date: July 26 to August 7, 1971 Type of mission: Manned lunar landing Country: The United States Country: The United States The Apollo 15 mission placed the United States' fourth scientific team on the lunar surface. The primary objectives of the mission were fulfilled: It returned to Earth with an abundance of new data on the geologic evolution of the Moon and set the stage, as an exploration prototype, for the Apollo 16 and 17 missions. Principal personages DAVID R. SCOTT, command pilot JAMES B. IRWIN, lunar module pilot ALFRED M. WORDEN, command module pilot Summary of the Mission Following the success of Apollo 14 six months earlier in the Fra Mauro area of the Moon, the Apollo 15 mission was designed to continue the United States' lunar investigations in the Hadley-Appenine Mountains, located along the southeastern rim of the Sea of Rains. National Aeronautics and Space Administration scientists were convinced that ancient rocks found in the mountainous regions peripheral to the multiringed Sea of Rains held the clue to the age and genesis of the primordial lunar crust. Apollo 15 was launched on schedule from Launch Complex 39A of the Kennedy Space Center in Florida on July 26, 1971, at 1334 Greenwich mean time (GMT). The launch vehicle was an 111-meter-high Saturn 5 rocket, capable of delivering more than 40 million newtons of thrust with its liquid oxygen and kerosene first stage and liquid oxygen and liquid hydrogen second and third stages.
