With all things SpaceX does, the second version of anything sees a large swath of improvements and changes; Starbase Pad B is no different. Here is a list of some of the biggest changes SpaceX is making to it.<\/p>\n<p><span id=\"more-43608\"><\/span><\/p>\n<h2 class=\"wp-block-heading\" id=\"h-finally-a-flame-trench\">Finally a flame trench<\/h2>\n<p class=\"wp-block-paragraph\">In what was one of the most called-out items during the construction of Pad A, Pad B will see the community\u2019s wish for a flame trench.<\/p>\n<p class=\"wp-block-paragraph\">During the early days of Starbase\u2019s construction, the theory for Pad A\u2019s construction was that Starship wouldn\u2019t have a launch pad on Mars, so it couldn\u2019t have too nice of a pad on Earth. Pad A was just a simple stand that allowed some space for the Starship\u2019s Raptor engines to fire beneath it.<\/p>\n<p class=\"wp-block-paragraph\">That simple design of just a flat concrete pad beneath the launch mount came to an end after Starship\u2019s first fully integrated launch. The after-launch effect on the ground left a massive crater, with large chunks of concrete being flung into the protected dunes and the Gulf of Mexico. Afterwards, SpaceX added a water-cooled steel plate beneath the pad for some added protection.<\/p>\n<p>\t<span class=\"outbrain-ad-label\"><\/span><\/p>\n<p>\t\t<script type=\"text\/plain\">\n\t\t\twindow.adSlotsConfig = window.adSlotsConfig || [];<\/p>\n<p>\t\t\tadSlotsConfig.push( {\n\t\t\t\tslotID: '\/1049447\/Outbrain',\n\t\t\t\tslotName: 'div-gpt-ad-outbrain-ad-43608',\n\t\t\t\tsizes: [300, 250],\n\t\t\t\tslotPosition: 'mid_article'\n\t\t\t} );\n\t\t<\/script><\/p>\n<p class=\"wp-block-paragraph\">Pad B will feature a dedicated flame trench and diverter, similar to what has traditionally been seen at most launch pads. The work to excavate the ground needed for the trench has constituted the bulk of the work to build Pad B so far, given Starbase\u2018s difficult terrain.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-redesigned-launch-mount\">Redesigned launch mount<\/h2>\n<p class=\"wp-block-paragraph\">Sitting on top of that flame trench is the newly designed launch mount. Much more built up than Pad A\u2019s, Pad B\u2019s launch mount is square and took nearly a year to assemble. This is where Starship\u2019s booster will be placed prior to launch, and it is designed to be a steady base to support rapid launches for the fully reusable rocket.<\/p>\n<p class=\"wp-block-paragraph\">The mount features a water-cooled deck and is much more robust than the previous version, hopefully meaning it will stand up longer to Starship\u2019s beating and mean less downtime between launches.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-shorter-catch-arms\">Shorter catch arms<\/h2>\n<p class=\"wp-block-paragraph\">One of the most notable changes, besides the flame trench, is the shortening of Pad B\u2019s catch arms. Also known as \u201cChopsticks,\u201d the arms are what \u201ccatch\u201d the Starship booster and eventually the Starship upper stage. For Pad B, these arms are noticeably shorter than on Pad A, and it\u2019s not a mistake.<\/p>\n<p class=\"wp-block-paragraph\">If you\u2019ve noticed on previous successful booster catches, the booster is normally caught towards the middle of the arms. SpaceX has been pretty accurate with its catches, not missing a single one. So it seems like the company is confident it can shorten the arms without fearing not having enough room for catches.<\/p>\n<p class=\"wp-block-paragraph\">The shorter arms also make moving them easier. The lighter weight and shorter length mean that SpaceX can move them quicker and with the same or less energy to do so. So an overall win-win.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-overall-infrastructure-improvements\">Overall infrastructure improvements<\/h2>\n<p class=\"wp-block-paragraph\">If you have been following SpaceX for a long time, you\u2019ll know they have a pretty simple process for new projects: build something that works, find the weaknesses, improve on it where they can, and then finally create a final process that fixes everything. While SpaceX has made plenty of changes to Pad A to improve its design, Pad B is a completely new design that will make SpaceX\u2019s dream of a rapidly reusable rocket much closer to reality.<\/p>\n<p class=\"wp-block-paragraph\">From new pumps to underground insulated pipes, Pad B is built to be the long-term home of Starship for years, if not decades, to come.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-changes-coming-to-pad-a-florida\">Changes coming to Pad A? Florida?<\/h2>\n<p class=\"wp-block-paragraph\">With all these improvements being seen coming to Pad B, does this mean Pad A will become obsolete once it\u2019s finished? Likely so. Once Pad B is finished, it is very likely that all launch operations are moved to Pad B with the fate of Pad A being unknown. Pad A could be partially torn down and work could begin on it to match Pad B\u2019s design; Pad A could also go on for some time as a test stand for Starship boosters.<\/p>\n<p class=\"wp-block-paragraph\">What is even more likely, or even confirmed, is the design of Starbase Pad B coming to Florida\u2019s LC-39A Starship launch site. SpaceX has already begun work on digging out a flame trench at the historic launch site, and aerial images show that work on a similar square launch mount is underway.<\/p>\n<p class=\"wp-block-paragraph\">If SpaceX is as predictable as they can sometimes be with projects like this, the company will likely find any improvements they missed on Starbase Pad B and add them to the Pad A and LC-39A designs.<\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"inline_featured_image":false,"footnotes":"","_links_to":"","_links_to_target":""},"categories":[2],"tags":[],"class_list":["post-21352","post","type-post","status-publish","format-standard","hentry","category-news"],"acf":[],"_links":{"self":[{"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/posts\/21352"}],"collection":[{"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/comments?post=21352"}],"version-history":[{"count":0,"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/posts\/21352\/revisions"}],"wp:attachment":[{"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/media?parent=21352"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/categories?post=21352"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/tags?post=21352"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
