Image: Adam Bernstein\/Spaceflight Now<\/figcaption><\/figure>\n<p>United Launch Alliance fired off a next-generation Vulcan rocket Friday in the second of two \u201ccertification\u201d test flights needed before the new launcher can be used to carry high-priority national security payloads for the U.S. Space Force and the National Reconnaissance Office.<\/p>\n<p>One of two solid-propellant strap-on boosters provided by Northrop Grumman suffered an anomaly of some sort during the climb out of the lower atmosphere, but the Vulcan managed to continue on into orbit. What impact the issue might have on the Vulcan\u2019s certification is not yet known, but ULA CEO Tory Bruno said it will be investigated.<\/p>\n<p>\u201cThe trajectory was nominal throughout,\u201d he said on the company\u2019s launch webcast. \u201cWe did, however have an observation on SRB No. 1, so we will be off looking at that after the mission is complete.\u201d No other details were provided.<\/p>\n<p>The Vulcan\u2019s two Blue Origin-built BE-4 engines and twin solid rocket boosters, or SRBs thundered to life at 7:25 a.m. EDT, shattering the morning calm with the crackling roar of 2 million pounds of thrust.<\/p>\n<p>The 202-foot-tall, 1.5-million-pound rocket, decked out in a swirling red-and-white livery, climbed skyward from launch complex 41 at the Cape Canaveral Space Force Station, rapidly accelerating out of the dense lower atmosphere on an easterly trajectory.<\/p>\n<p>The apparent booster anomaly could be seen in long-range tracking camera views when a shower of sparks and what looked like debris fell away from the right-side SRB 37 seconds after liftoff. The problem appeared to originate at or near the nozzle at the base of the booster. The exhaust plume changed shape dramatically, but the Vulcan was able to continue its climb to space.<\/p>\n<p>The anomaly aside, the strap-on boosters burned out and were jettisoned about 20 seconds later than planned. The methane-burning BE-4s, each one generating 550,000 pounds of thrust, continued boosting the rocket out of the lower atmosphere for another three minutes or so before shutting down.<\/p>\n<p>The non-reusable stage then fell away to crash into the Atlantic and the flight continued on the power of the Centaur 5 upper stage\u2019s two Aerojet Rocketdyne RL10C engines.<\/p>\n<p>The upper stage fired its engines a second time after reaching orbit to demonstrate its ability to restart in space, a key requirement for military payloads requiring complex \u201chigh energy\u201d trajectories to reach their operational orbits.<\/p>\n<p>The Vulcan\u2019s maiden launch on January 8 went off without a hitch, successfully sending a commercially-built moon lander on its way. For its second flight, ULA initially planned to launch a Sierra Space\u2019s winged cargo ship \u2014 Dream Chaser \u2014 on its maiden flight, but the spacecraft could not be delivered in time.<\/p>\n<p>Instead, ULA put a dummy payload atop the Vulcan, a so-called \u201cmass simulator,\u201d added a few technology demonstration experiments to help enable long-during flights and installed extra instrumentation to record as much data as possible during the 54-minute demonstration.<\/p>\n<p>The \u201ccert 2\u201d mission \u201chas literally one primary objective, which is to go fly a second time and have another success,\u201d Bruno said before launch. Assuming a review of the flight data confirms good performance, he added, \u201cthen you\u2019re ready to fly national security\u201d payloads.<\/p>\n<p>How the solid fuel booster issue might play into that data review and the rocket\u2019s eventual certification is not yet known.<\/p>\n<p>But two such missions are planned later this year, which Bruno described as \u201curgent.\u201d While he did not mention any possible Space Force or NRO payloads, national security missions typically launch satellites capable of optical and radar imaging, electronic eavesdropping, encrypted communications relay and other top-secret payloads.<\/p>\n<p>Because the Vulcan did not carry an active payload for its second flight, ULA added \u201cmore instrumentation that we\u2019re able to use for just characterizing a vehicle,\u201d Bruno said.<\/p>\n<p>\u201cWe\u2019re putting all kinds of other instruments (in) just to help us better understand how the rocket works as we go forward. So that\u2019s the mission, a second flight to become certified, and then some technology experiments of our own.\u201d<\/p>\n<p>ULA managers describe the Vulcan as \u201cthe future of our company.\u201d It is replacing the Delta 4 family of rockets, which have already been retired, and the venerable Atlas line that dates back to the early days of the U.S. space program.<\/p>\n<p>ULA still has 15 Atlas 5 rockets in its inventory. Eight will be used to launch Amazon Kuiper internet relay satellites, six are reserved to launch Boeing\u2019s Starliner crew ferry ship to the International Space Station and one is earmarked to boost a Viasat communications satellite into orbit.<\/p>\n<p>Once those missions are flown over the next several years, the Vulcan will be the company\u2019s sole launcher.<\/p>\n<p>\u201cThe system that we\u2019ve developed is really positioning us for a very bright, prosperous future for many, many years to come,\u201d Mark Peller, ULA\u2019s vice president of Vulcan development, said before the rocket\u2019s maiden flight. \u201cIt has proven to already be an extremely competitive product in the marketplace, having an order book of over 70 missions before first flight.\u201d<\/p>\n<p>Unlike the Atlas 5, which uses Russian-built RD-180 engines to power the rocket\u2019s first stage, the all-American powered Vulcan relies on two BE-4 first stage engines built by Blue Origin, the space company owned by Amazon founder Jeff Bezos.<\/p>\n<p>At liftoff, the twin BE-4s generate a combined 1.1 million pounds of thrust. The two strap-on solid-propellant boosters generate another 919,200 pounds of push, providing a total thrust of just over 2 million pounds. The Vulcan can be launched with up to six strap ons depending on mission requirements.<\/p>\n<p>The hydrogen-fueled Centaur 5 upper stage engines generates 23,825 pounds of thrust, enabling launch of heavy military payloads to so-called high-energy orbits that can\u2019t be easily reached by rockets optimized for low-Earth orbit.<\/p>\n<p>Bruno would not reveal the cost of a Vulcan rocket, other than to say it was less than $100 million, making it competitive with SpaceX\u2019s Falcon 9 and Falcon Heavy rockets.<\/p>\n<p>\u201cNext up after the after this mission will be a couple of missions for the Space Force,\u201d Bruno said. \u201cWe expect those to be ready to go this year, hence the urgency and not being able to wait any longer for the Dream Chaser.\u201d<\/p>\n<\/p><\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/spaceflightnow.com\/2024\/10\/04\/ula-launches-second-vulcan-flight-encounters-strap-on-booster-anomaly\/\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>By thirty-seven seconds after liftoff, it was clear one of two strap-on solid fuel boostersvwas suffered an anomaly as can be seen by sparks and debris falling away from the &hellip; <a href=\"https:\/\/hotvideos24.online\/?p=110457\" class=\"more-link\">Read More<\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8628],"tags":[],"class_list":["post-110457","post","type-post","status-publish","format-standard","hentry","category-science","entry"],"_links":{"self":[{"href":"https:\/\/hotvideos24.online\/index.php?rest_route=\/wp\/v2\/posts\/110457","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hotvideos24.online\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/hotvideos24.online\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/hotvideos24.online\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/hotvideos24.online\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=110457"}],"version-history":[{"count":0,"href":"https:\/\/hotvideos24.online\/index.php?rest_route=\/wp\/v2\/posts\/110457\/revisions"}],"wp:attachment":[{"href":"https:\/\/hotvideos24.online\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=110457"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/hotvideos24.online\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=110457"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/hotvideos24.online\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=110457"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
