Pioneer Venus Mission

The Orbiter and Multiprobe used the same basic Pioneer Bus in order to reduce the cost of the mission. The Multiprobe carried four probes (one large probe and three identical small probes). After approaching Venus, the Multiprobe released its four probes along with the Bus toward different target areas on the surface of the planet. The Orbiter was designed to explore Venus.in four ways 7 . To investigate the clouds of the entire planet . To measure the characteristics of upper atmosphere and...

Mariner Program

The Mariner Program consisted of 10 launches with the initial launch in 1962 and the final launch more than ten years later (1973). These missions were space probes that involved the exploration of other planets in our solar system. Table 9.1 shows the highlights of the Mariner Missions 1 . Missions 1, 3, and 8 failed for various reasons. The spacecrafts that will be discussed are Mariners 2 and 5, Mariners 6 and 7, and Mariner 10 because these missions explored Venus, Mars, and Venus Mercury,...

Skylab

After approximately 3900 orbits of the earth with 171 days of manned operation from its launch in May 1973, Skylab 1 was a project of unparalleled scientific scope and breadth 1 . There were three visits to Skylab 1 as indicated in Table 5-1 2 . Upon launching Skylab 1, its meteroid shield was torn away from the exterior of the cylindrical workshop along with one of the retracted solar wings. The second solar panel had not been properly deployed, resulting in an overheated and underpowered...

Lunar Orbiter Program

The Lunar Orbiter program consisted of five spacecraft missions launched between August, 1966 and August, 1967 and was the second of the three unmanned projects (Ranger, Lunar Orbiter, and Surveyor Programs). The main focus of the program was to aid in the selection of Apollo landing sites in the equatorial regions of the Moon 1,2 . During the first three missions, 20 potential lunar landing sites were photographed from low-inclination and relatively low-altitude orbits. Missions four and five,...

Apollo Program

The first Apollo mission launch date was October 27, 1961 and it verified the Saturn I's aerodynamic and structural design. A series of five more launches were conducted before the first manned Apollo launch was made on October 11, 1968. See Table 4.1 for details of Apollo missions 1 . On July 16, 1969, man landed on the moon Apollo 11 mission followed by five more moon landings. The last launch was on December 7, 1972. See Table I for The Apollo command and service module electrical power...

Project Gemini

Experience from Project Mercury demonstrated that failure propagation can occur when the systems are designed such that there is an interdependency or when systems are installed in a stacked fashion with common interfaces. In order to remove this constraint, Gemini development program emphasized rigorous . Component Testing . Subsystem Testing . Integrated Systems Testing The Gemini systems were almost exclusively installed In a modular structure outside the inner pressure vessel and were...

Viking Project

The principle objective of the Viking Project was to send two vehicles, each consisting of an Orbiter System and a Lander System, to Mars to perform scientific experiments to enlarge our present knowledge about the physical characteristics of Mars, especially its ability for supporting life 1 . Viking 1 and 2 were launched in August and September, 1975, respectively. The design of the Viking Orbiter was essentially based on the Mariner spacecraft series. The design philosophy was to scale-up...
