      Rocket Report: Tough times Astra and Virgin; SpaceX upgrading launch pad

      news.movim.eu / ArsTechnica · Friday, 10 November, 2023 - 12:00 · 1 minute

    Welcome to Edition 6.19 of the Rocket Report! While we wait for SpaceX to launch the second full-scale test flight of Starship, a lot of the news this week involved companies with much smaller rockets. Astra is struggling to find enough funding to remain in business, and Virgin Galactic says it will fly its suborbital Unity spaceplane for the last time next year to focus on construction of new Delta-class ships that should be easier to turn around between flights. It's a tough time to raise money, and more space companies will face difficult decisions to stay alive in the months ahead.

    Virgin Galactic plans "pause" in flight operations. Virgin Galactic will reduce the frequency of flights of its current suborbital vehicle and stop them entirely by mid-2024 as it concentrates resources on the next generation of vehicles, Space News reports . This was unexpected news for anyone outside of the company. As Ars has previously reported , Virgin Galactic has ramped up the flight rate for its VSS Unity suborbital spaceplane to about one mission per month, a rather impressive cadence, especially when Blue Origin, the other player in the suborbital human spaceflight market, has not flown any people to space in more than a year.

      After the sting of Ariane 6, Europe finally embraces commercial rockets

    Representatives from 22 European countries reached an agreement Monday to change the way the continent's rockets are developed, moving from a government-driven approach to a commercial paradigm that appears to be modeled after how NASA and the US military do business.

    This is a big moment for the European Space Agency and its member states, which have traditionally funded the lion's share of rocket development costs since the start of Europe's launcher programs more than half a century ago. Josef Aschbacher, a scientist who took over as director general of ESA in 2021, has argued that Europe is in an "acute launcher crisis" now that the continent lacks independent launch capability for most of its space missions.

    Officials from ESA's 22 member states met Monday for a Space Summit in Seville, Spain , to decide on several priorities for the space agency. The rocket question was perhaps the most pressing among the topics up for discussion.

      Ariane 6 cost and delays bring European launch industry to a breaking point

    European space officials will convene on Monday and Tuesday to discuss the future of space policy for the continent. The "Space Summit" gathering in Seville, Spain, will encompass several topics, including the future of launch.

    "Seville will be a very decisive moment for space in Europe," said the director general of the European Space Agency, Josef Aschbacher, on the eve of the summit. "On launchers, and on exploration, I expect ministers to really make very bold decisions. I certainly expect a paradigm shift on the launcher sector."

    Aschbacher has previously described Europe's rocket predicament—the venerable Ariane 5 has retired, its replacement, Ariane 6, is not ready, and the smaller Vega C rocket is also having teething problems—as an acute crisis. Now, it's possible this crisis will lead to the breakup of a decades-long partnership in Europe, led by the nations of France, Germany, and Italy, to collaborate on the development of launch capabilities.

      Rocket Report: China launches 3-man crew; SpaceX adds to busy manifest

    Welcome to Edition 6.17 of the Rocket Report! Two Asian powers notched achievements in their human spaceflight programs this week. In China, three astronauts launched to begin a six-month expedition on the Tiangong space station. With this mission, China is settling into a routine of operations on the Tiangong complex. Elsewhere in Asia, India took strides toward launching its own astronauts with a successful test of a launch abort system for the country's Gaganyaan spacecraft, which could fly people into low-Earth orbit in 2025. This is welcome news for US officials because India could help offer a counterweight to China's dominance (among Asian countries) in spaceflight.

    India tests escape system for human-rated crew capsule. India aced the first in-flight test of the crew escape system for the country's Gaganyaan spacecraft Saturday, Ars reports . With this flight, India tested the set of rocket motors and parachutes that would propel the spacecraft away from a failing launch vehicle, a dramatic maneuver that would save the lives of everyone on board. An unpressurized version of the Gaganyaan capsule launched, without anyone aboard, on top of a single-stage liquid-fueled rocket. About a minute later, soon after the rocket surpassed the speed of sound, the vehicle triggered the abort maneuver, and the capsule separated from the booster to parachute into the sea. By all accounts, Indian officials were thrilled with the outcome of the test flight.

      La crise des fusées précipite l’Europe dans les bras de SpaceX

    Falcon 9 SpaceX

    L'Europe spatiale se trouve dans un trou capacitaire : elle n'a plus aucune fusée Ariane 5. Le lanceur Vega-C est indisponible. Soyouz est hors-jeu. Enfin, Ariane 6 n'est pas prête. Or, pour assurer le lancement d'autres satellites Galileo, l'Europe va devoir composer avec l'Américain SpaceX. [Lire la suite]

      Oops—It looks like the Ariane 6 rocket may not offer Europe any launch savings

    Nearly a decade ago the European Space Agency announced plans to develop the next generation of its Ariane rocket, the Ariane 6 booster. The goal was to bring a less costly workhorse rocket to market that could compete with the likes of SpaceX's Falcon 9 booster and begin flying by 2020.

    It has been well documented that development of the Ariane 6 is running years behind —the vehicle is now unlikely to fly before the middle of 2024 and subject to further delays. For example, a critical long-duration hot fire of the vehicle's Vulcain 2.1 main engine had been scheduled for "early October," but there have been no recent updates on when this key test will take place.

    However, there are also increasing concerns that the Ariane 6 rocket will not meet its ambitious price targets. For years, European officials have said they would like to cut the price of launches by half with a rocket that is easier to manufacture and by flying an increased cadence of missions.
