After nine years in merely 200 flights to the edge of space the X15 program is brought to close with 8 final flights in 1968. The half rocket half plane has been a unique test bed for researching aeronautics and space problems. The giant XP70 flying at three times the speed of sound makes 13 research flights gathering date for use in the development of large super sonic air craft. Extensive flight studies are also made on several types of vertical take off from landing planes. 0:48 as they are called can take off vertically then move forward like any other plane. Much aeronautic research is done with models and this particular test a highly instrumented model is dropped by a helicopter, and then flown by radio control from the ground. This type of study makes the most rigorist test possible without the danger to a pilot will be expense of a real craft. As already mentioned jet air craft noise is a continuing major problem. NASA tries out various engine modifications to find out the effect of an air craft performance. It’s discovered that by cutting woods in an airport run way, planes can land with less chance of skidding and stop easier. In 1968 the tests continue, some of the breaking tests are made by using specially instrumented cars on the runways. Now the results appear to have applications to highways as well as landing strips. At the nuclear rocket development station in Nevada, a powerful nuclear rocket reactor is tested. To test the part of an airport to develop nuclear powered rockets for futures deep space exploration. Apollo can be likened to a finely tuned watch, man and space machines are perfected to the highest degree possible. In most cases the astronauts will fly the space craft trained separately but concurrent with the build up and development of the space machines themselves. And brought together they must smash smoothly theirs a little room for aero. Apollo is like this and the man who fly and the man who built know it. There are four Apollo flights in 1968. Two women and two man, all part of the preparation for moon landing. Apollo five send them off to check out the lunar module. It’s in a lunar module that two astronauts will land and take off from the moon. Both the decent engine used to slow the space craft for the landing and the ascend engine that will boost the pair of the moon are successfully tested. To further ready the second five rockets in its many components in unmanned Apollo six is launched into orbit. Engineering cameras on board we called the first stage and into stage separations. After 10 hours in space the command module is rammed back into the earth’s atmosphere simulating a lunar return. Another milestone in preparing from moon mission, the next step, check out the space craft with men aboard. Here astronaut Sheera, Cunningham, and Aisley move about weightlessly in their Apollo 7 spacecraft. This is also the first full dress rehearsal for the man spacecraft tracking network. 14 ground stations located in such places as Bermuda, Australia, Spain, and Hawaii together with planes and tracking ships keeping and electronic edge tuned to the Apollo spacecraft. After 10 days in a 163 revolutions Apollo 7 splash down in the pacific. Paving the way for the fist half million mile journey in the moon and back. The settled 5 rocket boost the Apollo 8 astronaut boomed and level and end us to world they rendezvous with the moon. The first time the big rocket is flown with men as passengers. With on route, the crew keeps busy checking and double checking all systems as they speed towards the moon. Many of the things they do are to have direct bearing on the future lunar missions. Merely three days and 230 thousand miles later, the crews of Apollo 8 fire their rocker engine placing them in lunar orbit. Here are some of the views recorded by the crew as they orbit ten times showing remarkable detail. The kind of detail needed before man can land their. Then the cameras and spacecraft returned towa
