Action and Reaction in Rockets<\/figcaption><\/figure>\nHerein lies the issue – since there is nothing in space to push against, rockets will always need to eject some sort of mass (or energy) in order to gain velocity in the opposite direction. There’s just no workaround to that sort of limitation set by the laws of physics.<\/p>\n
The thrust system alone, for electric rocket, is not the only problem; but even the amount of thrust that needs to be generated is a huge burden. A rocket needs to attain a velocity of at least 40,270 km\/h (25,020 mph) to escape the earth\u2019s gravity and move into orbit. Attaining this high a velocity, especially in the atmosphere with motion powered by electricity alone is close to impossible with our current technology. Airplanes generally require a velocity of 150\u2013180 mph (240\u2013285 km\/h) or even less for normal take-off.<\/p>\n
NASA has recently announced that it is developing a fully electric aircraft named \u2018Maxwell\u2019, or \u2018X-57\u2019. The aircraft will be powered by 14 electric motors with the first test flight planned for 2017. This is indeed fascinating technology, although the top speed may only be 175 mph (282 km\/h) for now. NASA is also very excited to see how this technology will evolve as it has a potential to transform the entire aviation industry and perhaps even rocket systems.<\/p>\n
It’d be wise to remind ourselves that there does exist a vast ocean of unexplored science, along with our limitless imagination of course. While there really isnt any violating Newton’s Third Law, there must be a workaround to it, waiting for us to be discovered.<\/p>\n","protected":false},"excerpt":{"rendered":"
Humans have mostly depended on chemical combustion to power most of their transportation needs. From motorcycles to airplanes and especially rockets, we generally depend on energy from chemical fuels to cause motion. The enormous amounts of fuels we use are of course, causing pollution. The issues aren’t just limited to environmental reasons in the case…<\/p>\n","protected":false},"author":2,"featured_media":23946,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[81,216,240],"_links":{"self":[{"href":"https:\/\/entropymag.co\/wp-json\/wp\/v2\/posts\/23945"}],"collection":[{"href":"https:\/\/entropymag.co\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/entropymag.co\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/entropymag.co\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/entropymag.co\/wp-json\/wp\/v2\/comments?post=23945"}],"version-history":[{"count":0,"href":"https:\/\/entropymag.co\/wp-json\/wp\/v2\/posts\/23945\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/entropymag.co\/wp-json\/"}],"wp:attachment":[{"href":"https:\/\/entropymag.co\/wp-json\/wp\/v2\/media?parent=23945"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/entropymag.co\/wp-json\/wp\/v2\/categories?post=23945"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/entropymag.co\/wp-json\/wp\/v2\/tags?post=23945"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
