Four months after laying off nearly the wholeety of its – – person staff, the micro-launch company filed for bankruptcy on December (**********************************************************************************, **************************************** SpaceNews reports. Vector had been one of the leading companies in the small-launch-vehicle market until August, when the company said that a “significant change in financing” led it to pause operations.****************************************** Funding falls through … The publication said the August layoffs were triggered when one of the company major investors, venture fund Sequoia, withdrew its support due to concerns about how the company was managed. That came as Vector was working on a new funding round, and Sequoia’s decision had a domino effect, causing other investors to back out.

Earlier this month, the (th flight of India’s Polar Satellite Launch Vehicle successfully delivered spacecraft from five nations into orbit. This mission was also the th overall launch from India’s primary spaceport at Sriharikota, (Spaceflight Now reports) .********************************* (Two failures) … The PSLV’s first mission lifted off from Sriharikota on September (******************************************************************************, (****************************************************************, but failed to reach orbit after encountering a problem during separation of the rocket’s second and third stages. The PSLV’s only other launch failure occurred August (*****************************************************************************, , when the rocket’s payload shroud did not jettison, preventing the rocket from placing an Indian navigation satellite into orbit. The rocket has become a workhorse in the small-satellite launch industry.
****************************** (Exos Aerospace identifies cause of launch failure) . Exos has found the cause of the October launch failure of its Suborbital Autonomous Rocket with Guidance (aka SARGE rocket), according to the company co-founder. John Quinn, Exos Aerospace’s co-founder and chief operating officer,told Space.comthat a composite part just below the nose cone failed, causing the cone to slide down into the rocket. The booster then flew nearly horizontally, beyond any hope of recovery.********************************* (Sticking with it) … “What’s really interesting is, the component that failed was one that we replaced,” Quinn said. The replacement was made based on data gathered during the third company launch, which was successful. But engineers saw some moderate signs of stress in the composite part, so they decided to put in a new piece for the fourth launch. The company is already targeting another launch date for the first quarter of (**********************************************************, depending on the progress of the redesign and certain external matters, such as the renewal of its government launch license.

This was the th total test flight of the New Shepard launch system , and the third such flight in the year 41586,NASASpaceFlight.com reports.********************************** (Human flights in) ********************************************************? … This mission is expected to be one of the last uncrewed flights scheduled to occur before Blue Origin gets ready to fly human passengers on the New Shepard vehicle, with the first crewed launch most likely occurring sometime next year. The company has yet to begin selling tickets or even set a price for the 10 – minute, out-of-this-world experience. Maybe that changes next year. Maybe not. (submitted by Ken the Bin) Trump ally buys Stratolaunch. Geek Wire reportsthat the new owner of Stratolaunch, the space venture started by late Microsoft co-founder Paul Allen, is Steve Feinberg, a secretive billionaire with close ties to President Donald Trump. In October, Stratolaunch announced that it had transitioned ownership from Allen’s holding company, Vulcan Inc., but it did not identify who had bought the company. Jean Floyd says for now… Private-equity firms typically replace existing managers as a prelude to realigning businesses they buy, which can involve firing, automation and offshoring. However, it appears that Jean Floyd, Stratolaunch’s president and CEO since (**************************************************************, remains in his role for now. Last week, Floyd tweeted that Stratolaunch had grown from (to 150 employees over the past two months. He also reported that the company’s new mission was “to be the world’s leading provider of high-speed flight-test services.” Maybe in We’ll see what that means. Copper-titanium alloys show promise
. The current titanium alloys often used in additive manufacturing typically cool and bond together into crystals that make them prone to cracking. However, a new report inthe journal Naturesuggests that a titanium-copper alloy may solve these problems and allow for the stronger material to be used more widely. Building a stronger booster?… “We report on the development of titanium-copper alloys that have a high constitutional super-cooling capacity as a result of partitioning of the alloying element during solidification, which can override the negative effect of a high thermal gradient in the laser-melted region during additive manufacturing, “authors write in the journal. They say this could have applications in the aerospace and biomedical industries. This work remains at the laboratory level for now, but it could have long-term implications for spaceflight.
