The objectives of the Commercial Crew & Cargo Program are to implement U.S. Space Exploration policy with investments to stimulate the commercial space industry; facilitate U.S. private industry demonstration of cargo and crew space transportation capabilities with the goal of achieving safe, reliable, cost effective access to low-Earth orbit; and create a market environment in which commercial space transportation services are available to Government and private sector customers.
A test fire of the rocket Friday evening prompted an announcement from SpaceX that it will review data for several days. The Air Force’s 45th Space Wing, which manages the area around the launch pad and the safety zone in the Atlantic Ocean, still had a May 7 launch date on its website, but SpaceX itself hasn’t set a date, which makes a Monday launch unlikely. 0139名無しさん@お腹いっぱい。2018/05/08(火) 00:07:49.98ID:LRwZlZPr 不当手形出しそうw 0140名無しさん@お腹いっぱい。2018/05/08(火) 00:21:24.30ID:gN+QaJJv ブロック5は失敗作みたいね NASAの要求が高すぎた 0141名無しさん@お腹いっぱい。2018/05/08(火) 00:51:55.34ID:LRwZlZPr 例えは何だが 結局Googleの月探査レースみたいなもの 誰もロケットが上げられ無いんだし 現実はあの程度w だからロシアや日本が凌駕してるのw 0142名無しさん@お腹いっぱい。2018/05/08(火) 01:55:41.85ID:+Nl47s8o 安全率はいろいろ種類があって、単に安全率っていわれるとなにかわからん 宇宙じゃよくLOC率?がつかわれる 0143名無しさん@お腹いっぱい。2018/05/08(火) 05:57:20.11ID:GqvqTvHN>>141 何が「だから」で、何で「ロシア」と「日本」なのか。 相変わらず脳みそ膿んでるな。 0144名無しさん@お腹いっぱい。2018/05/08(火) 07:40:35.53ID:i0Eep1lT いつものキチガイの自演かね? 01451342018/05/08(火) 08:16:48.43ID:vnq2h3Hl>>136 レスサンクスです。ふむむ。 0146名無しさん@お腹いっぱい。2018/05/08(火) 08:47:11.51ID:bx1hqhup SpX-14 ドラゴン補給船、地球へ帰還 https://sorae.info/030201/2018_05_07_iss.html ステーションから切り離されたドラゴン補給船には、 2トン以上の資材が搭載されていました。 搭載されていたのは宇宙ステーションで飼育されていたマウスや、 植物や昆虫のサンプルなどの科学実験資材です。 これらは地上でさらに詳細な分析と研究が実施される予定です。
SpaceX is now targeting no earlier than Thursday for its Block 5 Falcon 9 launch from Kennedy Space Center. Teams have a window from 4:12 p.m. to 6:22 p.m. to launch Bangabandhu-1 from pad 39A. 0151名無しさん@お腹いっぱい。2018/05/08(火) 19:30:29.42ID:gN+QaJJv また延期して来月になりそう 0152名無しさん@お腹いっぱい。2018/05/08(火) 21:20:21.10ID:vnq2h3Hl>>147 を投稿された方へ。 その長文を書く手間を他の宇宙開発関連のお話に割り当てていただけたらうれしいのですが。 どうぞよろしくお願い致します。 0153名無しさん@お腹いっぱい。2018/05/08(火) 21:29:45.74ID:oxKK87uZ>>152 君は該当者なのかい? 0154名無しさん@お腹いっぱい。2018/05/08(火) 22:38:43.07ID:bx1hqhup 自分に課した役割として、 ・長文翻訳の投稿 (好きでやってる) ・糖質荒らしの牽制 (やむを得ず)
The block 5 is the last major iteration of the Falcon 9, and Musk said he expects some 300 flights, using 50 to 60 boosters, between now and when the rocket is retired in favor of SpaceX's gargantuan "BFR" rocket, a launch system he says will one day carry people to Mars.
・Really the 6th iteration of F9 ・8% increase in thrust of S1 ・Last major revision ・Up to 300 more flights with block 5 ・2nd stage has block 5 engine but will operate like a block 4 for this flight ・The interstage looks cool ・Re-flying same block 5 core within 24 hours next year ・Leg 2.0 ・No more aluminum grid fins ・Elon confident that full reusability of the Second Stage is achievable. ・Gaining data about 2nd stage entry now. They transmit to the Iridium constellation ・Will add thermal protection system to 2nd stge ・Fuel costs $300,000-400,000. Still hoping to get the marginal cost of a Falcon 9 launch down to $5-$6 million. ・first stage 60 percent of cost, 2nd stage 20, fairing 10, everything else 10 ・Expecting no unnecessary action between flights. Fold up legs, attach 2nd stage and go. ・First block 5 to 10 flights most likely next year. Big milestone Elon says. ・Need to take this booster apart after this flight since it's the first Block 5 ・Human rated rockets must be overdesigned by 40% for crew safety ・Boca Chica will be re-dedicated to BFR ・30 to 50 Block 5 cores planned ・SpaceX charging $50 million for flight proven flight, instead of $62 million for a new one. ・NASA can be a pain in the ass sometimes ・Load and Go issue has been overblown. CAN load fuel and then have astronauts board ・Massive amount of research and testing in COPV 2.0. Most advanced pressure vessel ever developed by humanity. 01851792018/05/12(土) 12:32:10.84ID:fT6nEbbU>>182様,>>183様 解説どうもありがとうございます。なるほどです。 0186名無しさん@お腹いっぱい。2018/05/12(土) 16:49:30.60ID:fT6nEbbU>>184 >Elon confident that full reusability of the Second Stage is achievable.
