These ions shoot out of the engine to propel the satellite.&nbsp;<\/li>\n\n\n\n<li>\u201cThe force of the engine\u2019s thrust is akin to the weight of two 10-cent coins in your palm \u2013 very little force. But in space, there is no air and therefore no friction, so the slightest and continual force from the thruster is enough to push the satellite to high accelerations,\u201d explained CTO George-Cristian Potrivitu.<\/li>\n\n\n\n<li>This remarkable milestone is also a cheaper option compared to expensive rare gases such as xenon, which makes up just 0.0000087% of Earth\u2019s atmosphere. CEO Mark Lim shared that it is also energy-intensive to extract it from air.<\/li>\n\n\n\n<li>\u201cA lot of energy and resources are needed to distill and purify the gas. Since xenon is so rare in the atmosphere, even more amounts of air need to be processed for just a small quantity of xenon,\u201d he said.<\/li>\n\n\n\n<li>Imagine this: with water now available as a source of fuel, satellites or even spacecraft in future deep space missions could potentially refuel at celestial bodies with signs of water.<\/li>\n\n\n\n<li>Read the full story on <a href=\"http:\/\/bit.ly\/3UC4PAy\">The Straits Times<\/a>.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>An invention that holds water<\/p>\n","protected":false},"author":5,"featured_media":4053,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_mo_disable_npp":"","footnotes":""},"categories":[322],"tags":[405],"class_list":["post-4052","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-daily","tag-aliena"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v19.1 -
