'Project Orion And Future Prospects For Nuclear Pulse Propulsion'. Journal of Propulsion and Power 18.3 (2002): 497‐504. Web. 4 May 2015. Main idea behind the paper : The only known existed technology which can theoretically lead human space exploration to a fraction of speed of light is Nuclear Pulse Propulsion (NPP). This paper was published with a view to making aerospace community concerned about the research and development done in the field of NPP about which very few people in engineering and science discipline were aware of. Although, the principle notion of this paper was regarding a quicker and the most efficient interplanetary space travel, the writer intended to draw the attention of this new technological era where NPP can do a lot besides space exploration. How are the authors approaching the problem? : The authors went towards this problem by introducing NPP. The classifications of NPP was clearly demonstrated with the trade offs of both methods i.e. External NPP with and without pusher plate, Internal NPP. The timeline of all kind of work which had been done on this project was clearly manifested with proper historical background. The writer viewed the envirmental and saftey issue as the main concern of interplanetary NPP space travel. At last, several possible solutions were stated by which NPP can be legalised for future human technological evolution and can open a new gate in the field of Aerospace. What are the key results? : In the context of space travel, the proposed solution was to build massive spacecraft to achieve the high specefic impulse to make NPP superior to other propulsion system, which was quite unrealistic at that time. To mitigate the issue of spallation and ablation of pusher plate, the author suggested to utilise carbon nanotube technology. Reducing the size of pusher plate through using electromagnetic field would improve the transfer of blast energy to the vehicle. Application of electromagnetic field can replace the use of pusher plate completely which can also reduce the erosion of pusher plate. How is this relevant to the aerospace community?: Since, the manned moon exploration in 1969, aerospace community did not see any other significant manned conquest. Building International Space Station (ISS) was a great achievement but human mars exploration till date has not been accomplished. Chemical rockets are meanigless and way too much expensive beyond the orbit of moon as a result aerospace community is always anticipating something innovative in the field of propulsion which will be more efficient, faster and less expensive. What is your professional opinion of this work? : The writer introduced NPP in a broad way which should be appreciated. But, there could have been more information regarding related future possible work which are happening now and perhaps in the near future, i.e. electromagnetic propulsion etc. Another, solution in making such project possible can be the real example of International Space Station (ISS) which had been constructed in space. It is not mandatory that the NPP based spacecraft should be made in the inner earth atmosphere, it can be done the same way as ISS was built.
