This article is written for SAE-UK by our Executive Director, Dr. Anthony Mc Donagh-Smith, showing an insight into previously unexhausted areas of NASA’s activities. Of particular interest to budding Rocket Scientists will be the effects on human and animal life of close proximity to rocket launches. Consequently, the Space Program has always been beset by tragedy and arguments over the worthiness of NASA’s budget. In this article the effects of rocket technology on its environment and, vice-versa, the effect of the political climate on the Space Program are both discussed.

The site was named the John F. Kennedy

 

Shuttle has showthat with the right methods it is possible to get back in a reusablevehicle which essentially glides back to Earth. The key is that the ceramic tiles can withstand the massive temperatures of 3000 Degrees Fahrenheit. The business of getting up there is still one of extreme risk.

The Greatest name ever in Rocket Science would have to be Werner Von Braun, initially an Officer in the SS he went on to lead the Space Program at NASA until the end of the Apollo Missions to the moon at which point he retired. Werner Von Braun always   proposed that the rocket method of launching in to Space was

 
 

Space Center after his assassination in 1963, prior to thatit was known as NASA’s Launch Operation Center. Before his death President Kennedy intended to move a second command centre to his home State of Massachusetts. His successor in the White House however hailed from Houston, Texas, the rest of that story requires little explanation.

Future plans for NASA

Only 2 more shuttle launches will be funded by October 10th, 2010. After 2010 when the last shuttle is scheduled to fly and Government funding for the Shuttle ceases - the Space Program returns to the more conventional method of astronauts atop rockets to launch them skywards. It seems that the era of the Shuttle has gone the same way as Concorde – too advanced for its time and overly hazardous. A simplistic view would be that there are essentially 2 problems regarding going into Space. Namely, the first is getting there and the second coming back again. The

 

too dangerous and indeed the tragedies of the Discovery and Columbia have confirmed that. Carrying humans on rockets filled with explosive propellants was not the ultimate ambition of Werner Von Braun. Instead the technologies that will eventually allow us a safer transport seem just as incredible now as the Shuttle did the first time it landed.

There are essentially two technologies that hold the greatest promise for the advent of truly sustainable space travel. The first is the scram-jet technology which will open up the supersonic, indeed hypersonic means of propulsion in the upper atmosphere – the gateway to ascending into orbit. This technology on test at NASA uses an air intake profile to compress the air rather than a conventional turbine blade. The result is massive thrust at high altitude and therefore high speeds. Anecdotally it is suggested that a journey onboard a ‘hypersonic’ or ‘scramjet’ plane from London to Sydney would take 2 hours.
