海外TECH	Engadget	SpaceX dominated private spaceflight in 2023, but its competitors (mostly) aren't quitting	https://www.engadget.com/spacex-dominated-private-spaceflight-in-2023-but-its-competitors-mostly-arent-quitting-153050005.html?src=rss	It s been a busy year for spaceflight ーthe busiest ever in fact This fall space companies once again broke the record for successful orbital launches in a single year with s th flight ーStarlink satellites sent up by SpaceX on November according to Ars Technica The number has since climbed to That pace has been driven in no small part by Elon Musk s aerospace venture which set a goal of hitting launches in and is nearly there with as of December Private companies have become key players in the new space race not only vying to serve as launch providers for science and communications missions but also ushering in the era of space tourism for anyone rich enough to nab a ticket But spaceflight is hard especially if you re trying to change the game with design innovations and for all the wins in there have been plenty of hiccups Here s a look at how some of the leading private space companies made out this year SpaceXREUTERS ReutersSpaceX seemingly didn t stop once to catch its breath in The company managed a record setting run of orbital launches with its reusable Falcon and partially reusable Falcon Heavy rockets with the lion s share dedicated to delivering its Starlink internet satellites to orbit there are now more than of them circling Earth SpaceX also delivered payloads for other entities including NASA and carried out multiple crewed flights with its Dragon capsule Four astronauts arrived at the International Space Station in March aboard a Crew Dragon and Axiom Space contracted SpaceX for a private astronaut mission that flew to the ISS in May As for its experimental Starship flights things were expectedly a bit more volatile Starship is the biggest and most powerful launch vehicle built to date and is designed to support future human spaceflight missions including NASA s return to the moon as soon as The spacecraft itself is feet tall and when stacked on top of the Super Heavy rocket the two tower at a combined feet Both Starship and Super Heavy are planned to be fully reusable It s all still in development and after a few years of suborbital flight tests without Super Heavy ーStarship has six of its own Raptor engines that enable flight ーthe vehicle advanced to orbital tests in SpaceX launched Starship for the first time in an integrated flight with its Super Heavy rocket on April and there were problems from the moment liftoff began Multiple engines failed and when Starship started its flip maneuver that allows for stage separation about minutes in it just kept spinning It was eventually given the command to self destruct ending the test with an explosion The launch left behind a lot of damage on the ground too tearing up the launchpad at SpaceX s Boca Chica test site creating a sizable crater and starting a acre fire on the grounds of a protected wildlife refuge But for SpaceX it was still considered a success ーits goal was just to clear the tower Starship made it to an altitude of about miles before it got caught in that uncontrolled spin Nevertheless the Federal Aviation Administration grounded Starship after the destructive test and ordered the company to complete dozens of corrective actions before it could fly again Starship did fly again before the end of and again Starship exploded This time though Starship officially made it to space climbing to about miles above Earth It also performed SpaceX s first attempt at hot staging ーwhere the upper stage begins to fire its engines while still attached to its lower stage ーand was able to complete separation from the Super Heavy booster It fell well short of the planned minute flight lasting only around eight minutes but it demonstrated hot staging was possible Blue OriginBlue OriginJeff Bezos Blue Origin had a strong run between late and with its reusable New Shepard suborbital booster and capsule completing six crewed flights to the edge of space following years of tests and payload missions for industry clients including NASA But in September one of its rockets suffered a main engine failure during an uncrewed research mission and New Shepard spent a subsequent months grounded After investigations into the cause of the event the company s then CEO Bob Smith ーwho is stepping down in the new year ーsaid in June that New Shepard would again be ready to go fly within the next few weeks pending FAA approval The FAA closed its investigation at the end of September and gave Blue Origin corrective actions to complete before New Shepard could take to the skies again Around that time Ars Technica reported that sources close to the matter said Blue Origin was targeting an October return to flight but that window came and went with no liftoff or further updates While it was starting to look like Blue Origin wouldn t fly at all in the company finally announced New Shepard s return in mid December and pulled off a successful suborbital payload flight on December It s mostly been crickets for Blue Origin s still in development New Glenn as the company races to get it ready for its debut New Glenn a partially reusable heavy lift vehicle is expected to make its inaugural flight sometime in It s already been tapped by NASA to send a pair of small satellites to Mars later that year but the timeline keeps slipping It was originally supposed to launch in but was later rescheduled to then and now The company shared some photos of the rocket s first and second stage being assembled at its Florida factory over the summer and confirmed to the Orlando Sentinel nbsp that it was still shooting for next year Blue Origin has also been busy building engines for another launch provider United Launch Alliance which will be used for ULA s heavy lift Vulcan Centaur rocket Both New Glenn and Vulcan will rely on Blue Origin s BE engine and have faced delays tied to its development Most recently in July CNBC reported that one of these engines exploded during testing at Blue Origin s West Texas facility United Launch AllianceREUTERS ReutersULA had a quiet year as well carrying out only three launches in with its Atlas V and Delta IV Heavy rockets ーdown from eight the year before Both rockets are in the process of winding down their operations ahead of their official retirement Delta IV Heavy has just one flight left which is expected to take place in and all of Atlas V s remaining flights have been sold and scheduled out over the next several years One of ULA s few launches was the first flight in its partnership with Amazon and an Atlas V rocket successfully delivered two of the company s prototype Project Kuiper internet satellites to orbit Most of ULA s attention right now is focused on putting the final touches on Vulcan ahead of its maiden flight Vulcan has been in development for roughly a decade and it too has faced years of delays There was some hope it would finally launch in the first half of with the company targeting liftoff in May but after the explosion of a Centaur upper stage during tests it pushed this target to the end of the year In October ULA had said it was planning to launch Vulcan for the first time on Christmas Eve from Cape Canaveral Florida But in an update posted this week the company confirmed Vulcan wouldn t be flying in after all nbsp Following a successful WDR the launch of ULA s first VulcanRocket flight test and Cert mission is planned for Jan pending range approval The Vulcan VCS rocket will launch from SLC from Cape Canaveral Space Force Station Florida pic twitter com gkHOBFFUTーULA ulalaunch December The rocket completed some critical tests in December and is now scheduled to fly on January Vulcan s first flight dubbed Certification will send Astrobotic s Peregrine lunar lander to the moon Once Vulcan is in operation ULA will start ramping up flights again It s already got a contract with Amazon for Project Kuiper launches on Vulcan It just needs to get off the ground first Rocket LabRocket LabOver the last few years Rocket Lab has risen as a company to watch in the launch sector In the first few months of it seemed on track to beat its record of nine orbital launches in one year with its Electron rocket The company told SpaceFlight Now it was targeting launches this time around It made it to seven by the end of August but in September a problem with the rocket s upper stage resulted in its failure to reach orbit Rocket Lab has at least three dozen successful Electron flights under its belt and only a handful of failures but the latest is the third such failure in as many years Whether or not it proves to be a major setback has yet to be seen The FAA in October cleared Rocket Lab to resume flights following the finalization of its investigation into the issue which wrapped up in November According to Rocket Lab the problem was caused by the rare interaction of three rare conditions in the low pressure space environment that created an unexpected electrical arc within the power supply system for the engine s motor controllers shorting the battery packs that provide power to the launch vehicle s second stage The company was still able to return to flight before the end of the year On December an Electron rocket delivered a Japanese satellite to orbit in a mission dubbed The Moon God Awakens Rocket Lab has been experimenting with different ways to recover its Electron boosters after flight ーincluding mid air catch attempts via helicopter ーas it works toward rocket reusability It s also developing a medium lift partially reusable launch vehicle Neutron that s expected to be completed in Virgin Galactic amp Virgin OrbitVirgin OrbitVirgin Galactic founded by Richard Branson managed a steady cadence of flights this year with its VSS Unity suborbital spaceplane The rocket powered craft made six flights in six months in including its first ever space tourism trip in August In addition to research missions it s now completed a total of four flights with paying tourists on board all of them completed between this summer and fall The company took a bit of a hit on the stock market in December though after Branson said he wouldn t be putting any more of his own money into it Speaking to the Financial Times Branson said We don t have the deepest pockets after COVID and Virgin Galactic has got billion or nearly It should I believe have sufficient funds to do its job on its own Following his comments shares took a nosedive But they ve since climbed back up Virgin Orbit on the other hand didn t fare so well in Branson s Virgin Galactic spinoff announced in May that it was shutting down a month after filing for Chapter bankruptcy The company was formed in with the intention of becoming a launch provider for small satellite missions It had a unique approach to getting payloads to space Virgin Orbit used a modified Boeing plane to launch its rocket LauncherOne from the air nbsp But it struggled to keep up with the competition and in January it suffered a failure during what was the first ever orbital launch from the UK As a result the satellites it had been commissioned by the UK and US governments to deliver didn t make it to orbit It was the company s second failure out of a total of just six missions and it proved unable to rebound Newcomers hit hurdlesCalifornia based Relativity Space has been working for years to build the first fully D printed reusable rockets with plans for an eventual medium to heavy lift vehicle that could send missions to the moon and Mars Its first rocket Terran had its inaugural launch in March this year but it failed not long after liftoff It hit some key milestones though making it through Max Q the point of maximum dynamic pressure on a spaceship during flight and stage separation Now Relativity Space is turning its attention to its larger vehicle Terran which it plans to have ready for launch in from Cape Canaveral ABL Space also based in California conducted its own first flight in with the launch of its RS rocket Shortly after liftoff all nine of RS s engines shut down causing the vehicle to crash back down to Earth In a Substack post at the end of October CEO Harry O Hanley detailed some of the work the company has been doing in the months since the first flight to prepare for its second launch but no date for Flight has been announced just yet More to come in David Ducros ESA ArianespaceIn many ways has felt like a primer for what s to come in which is shaping up to be a big year for spaceflight based on the timelines of current projects both private and government sponsored SpaceX has already said it s planning to hit launches a month in which would bring it to by the end of the year This year marked the end of the road for Arianespace s long running Ariane rocket which has become the leading launch vehicle in Europe for heavy missions over its years of service Ariane had its final flight in July leaving the continent with few launch options for big missions until the release of its successor Ariane Like others though Ariane has been hit by delay after delay over the years pushing it way behind its originally targeted debut The rocket which Arianespace is developing for the European Space Agency is expected to make its first flight in summer NASA and Boeing are planning the first crewed flight of the Starliner reusable spacecraft capsule which after being back for the umpteenth time this year is now slated to be ready around March NASA also plans to launch the next phase of its moon mission Artemis II as early as November It will be the second flight for NASA s Space Launch System SLS rocket and will have four astronauts aboard the Orion capsule for a lunar flyby But as always it d be reasonable to expect some delays This article originally appeared on Engadget at	2023-12-21 15:30:50
