\"Elon SpaceX<\/a> CEO Elon Musk<\/a> has revealed one of the biggest and hardest engineering challenges the company is facing presently in the Starship<\/a> rocket program. Musk said that orbital refuelling is the next major milestone for the Starship rocket, calling it \u201cone of the hardest engineering challenges that exist.\u201d Speaking at the X takeover event, Musk stressed on the complexity and ambition behind the SpaceX\u2019s reusable rocket program. \u201cI specialize in the impossible to merely late,\u201d Musk quipped, acknowledging delays in the Starship project but reaffirming its progress.<\/p>\n

Elon Musk talks about the hardest engineering challenge<\/p>\n

SpaceX CEO further explained that the process of orbital refuelling would need two Starships to dock somewhere in the orbit and then transfer propellant. Musk also floated the idea of an orbital propellant depot to streamline future missions to the Moon and Mars.Apart from this the another major hurdle is a fully reusable orbital heat shield. Musk emphasised that no one has yet created anything of this sort. He also acknowledged that the development of a reusable orbital heat shield is very critical to make Starship economically viable.\u201cNo one has ever created a fully reusable orbital heat shield before and no one’s created a fully reusable orbital rocket before,\u201d Musk said.Musk also reiterated that a reusable rocket and booster system can help bring down the cost below even the Falcon 1 rocket and can also revolutionise space logistics and enable commercial space travel.<\/p>\n

Elon Musk shares timeline of first Starship flight to Mars<\/p>\n

A user on X asked Musk about the timeline of Starship flight. \u201cWhat\u2019s the timeline you have set Elon? It sounds fascinating and I am glad to be alive when this is happening,\u201d an X user named @abhiyogi asked.Responding to the post, Musk wrote, \u201cSlight chance of Starship flight to Mars crewed by Optimus in Nov\/Dec next year. A lot needs to go right for that. More likely, first flight without humans in ~3.5 years, next flight ~5.5 years with humans. Mars city self-sustaining in 20 to 30 years.\u201d<\/p>\n

Reasons for the delay in Starship flight to Mars<\/p>\n

The new target of a crewed mission in approximately 5.5 years\u2014around 2030\u2014is a notable shift from previous, more optimistic predictions. It also follows recent technical hurdles, including ongoing delays in mastering orbital refuelling and the loss of Starship\u2019s upper stage during recent flight tests. The multiple technical issues which may be the cause of the delay include: failures in upper-stage Starship landings, unproven orbital refuelling systems and heat shield durability and rocket recovery mechanism.Earlier this year, SpaceX\u2019s Flight 9 achieved stage separation but it lost control during reentry. Musk however emphasised that mastering in-space propellant transfer is critical for deep-space travel and remains a top priority.<\/p>\n","protected":false},"excerpt":{"rendered":"SpaceX CEO Elon Musk has revealed one of the biggest and hardest engineering challenges the company is facing…\n","protected":false},"author":2,"featured_media":2274,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[74],"tags":[18,1647,2735,19,17,2734,2733,2732,2731,2730,82],"class_list":{"0":"post-2273","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-technology","8":"tag-eire","9":"tag-elon-musk","10":"tag-engineering-challenges","11":"tag-ie","12":"tag-ireland","13":"tag-mars-mission","14":"tag-orbital-refueling","15":"tag-reusable-rocket","16":"tag-spacex","17":"tag-starship","18":"tag-technology"},"share_on_mastodon":{"url":"","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/2273","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=2273"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/2273\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/2274"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=2273"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=2273"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=2273"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
