Reaching the Karman line, which is thought of as the outer boundary between usable airspace for aviation and spaceflight, is generally regarded as the first step to developing launch system technologies and serves as a good platform for understanding the technical challenges involved.<\/p>\n<p style=\"text-align: justify\">A team of forty students is involved to get the project underway and launch ready in just two years, which would make ASTRA the second student group to reach the Karman line and the only student group to achieve this with a hybrid rocket design.

This hybrid design allows us to comply with university and launch site regulations and will make transport a lot easier, even though the design is more challenging. The design features a 5kg payload and weighs around 275kg in total. Future design improvements will show how the final rocket will be constructed.<\/p>\n<p>This mission will provide valuable insight into the construction and design of a rocket as well as providing engineering data for further ASTRA projects like scientific payloads that require between 10-15 minutes of microgravity.<\/p>\n<p><strong>A short mission summary:\u00a0<\/strong><\/p>\n<p>Goal Altitude: 100km<br \/>Expected mass (wet): 275kg<br \/>Payload mass: 5kg<br \/>Propulsion: Hybrid<br \/>Fuel: Paraffin Wax<br \/>Oxidizer: N20<br \/>Max Thrust: 20 KN<br \/>Rocket Case: Aluminium 6061<br \/>Aerodynamic stability: Passive fins<br \/>Max G-Forces: 20g<br \/>Avionics: IMU and GPS<br \/>Recovery: Parachute deployment at 5km<\/p>\n<p>&nbsp;<\/p>\n<p>The current status of the Project can be tracked via our News page and with the help of our Project plan.<\/p><\/div>\n\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t<\/div><div class=\"et_d4_element et_pb_row et_pb_row_4  et_pb_css_mix_blend_mode et_block_row\">\n\t\t\t\t<div class=\"et_d4_element et_pb_column_4_4 et_pb_column et_pb_column_5  et_pb_css_mix_blend_mode et-last-child et_block_column\">\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t<div class=\"et_pb_module et_d4_element et_pb_text et_pb_text_3  et_pb_text_align_left et_pb_bg_layout_light\">\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\t\n\t\t\t\t\n\t\t\t<\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":13335,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_bbp_topic_count":0,"_bbp_reply_count":0,"_bbp_total_topic_count":0,"_bbp_total_reply_count":0,"_bbp_voice_count":0,"_bbp_anonymous_reply_count":0,"_bbp_topic_count_hidden":0,"_bbp_reply_count_hidden":0,"_bbp_forum_subforum_count":0,"_et_pb_use_builder":"on","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"class_list":["post-48","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/blogs.uni-bremen.de\/astra\/wp-json\/wp\/v2\/pages\/48","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blogs.uni-bremen.de\/astra\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/blogs.uni-bremen.de\/astra\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/blogs.uni-bremen.de\/astra\/wp-json\/wp\/v2\/users\/13335"}],"replies":[{"embeddable":true,"href":"https:\/\/blogs.uni-bremen.de\/astra\/wp-json\/wp\/v2\/comments?post=48"}],"version-history":[{"count":10,"href":"https:\/\/blogs.uni-bremen.de\/astra\/wp-json\/wp\/v2\/pages\/48\/revisions"}],"predecessor-version":[{"id":562,"href":"https:\/\/blogs.uni-bremen.de\/astra\/wp-json\/wp\/v2\/pages\/48\/revisions\/562"}],"wp:attachment":[{"href":"https:\/\/blogs.uni-bremen.de\/astra\/wp-json\/wp\/v2\/media?parent=48"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
