    NASA to unveil its heavy-lift rocket design
    September 14, 2011
    .
    Two stories, one from AP and the other from Florida Today, say that NASA will announce today the design of its heavy-lift rocket, mandated by Congress and estimated to cost around $35 billion. Here is NASA’s press release. To me, this is the key quote (from AP):

    NASA figures it will be building and launching about one rocket a year for about 15 years or more in the 2020s and 2030s, according to senior administration officials who spoke on the condition of anonymity because the announcement was not yet made. The idea is to launch its first unmanned test flight in 2017 with the first crew flying in 2021 and astronauts heading to a nearby asteroid in 2025, the officials said. From there, NASA hopes to send the rocket and astronauts to Mars — at first just to circle, but then later landing on the Red Planet — in the 2030s.

    In other words, after spending $1.7 on the National Space Plane, $1.2 billion on the X-33, $1 billion on the X-34, $800 million on the Space Launch Initiative, and finally, almost $10 billion on Constellation, none of which ever flew, NASA is now going to spend another $35 billion on a new rocket that won’t fly for at least another decade.

    To be really blunt, this new rocket, like all its predecessors, will never fly either. It costs too much, will take too long to build, and will certainly be canceled by a future administration before it is finished. It is therefore a complete waste of money, and any Congress that approves it will demonstrate how utterly insincere they are about controlling spending.

    A clarification: Some of the $35 billion mentioned above has already been spent for the Orion capsule. This however still does not change any of my conclusions.

    Culberson's ouster could spell big problems for NASA's Orion program, experts say
    .
    NASA programs -- especially Orion, which is focused on putting humans back on the moon -- could be in trouble after U.S. Rep. John Culberson lost his House seat Tuesday night to Lizzie Pannill Fletcher.

    Culberson, a Republican from Texas, has led the House appropriations committee that funds NASA for the last four years. And he's been a stanch advocate of science and human spaceflight over his nearly two decades in office, said Keith Cowing, editor of NASA Watch, a website devoted to space news.

    NASA ‘will eventually retire’ its new mega-rocket if SpaceX, Blue Origin can safely launch their own powerful rockets
    .
    NASA is building a giant rocket ship to return astronauts to the moon and, later on, ferry the first crews to and from Mars.

    But agency leaders are already contemplating the retirement of the Space Launch System (SLS), as the towering and yet-to-fly government rocket is called, and the Orion space capsule that’ll ride on top.

    NASA is anticipating the emergence of two reusable and presumably more affordable mega-rockets that private aerospace companies are creating. Those systems are the Big Falcon Rocket (BFR), which is being built by Elon Musk’s SpaceX; and the New Glenn, a launcher being built by Jeff Bezos’ Blue Origin.

    NASA to launch safety review of SpaceX and Boeing after video of Elon Musk smoking pot rankled agency leaders
    "We need to show the American public that when we put an astronaut on a rocket, they’ll be safe.”
    .
    NASA has ordered a safety review of the two companies it has hired to fly astronauts to the International Space Station, a months-long assessment that would involve hundreds of interviews designed to evaluate the culture of the workplaces, the agency said.

    The review, to begin next year, would look at both Boeing and SpaceX, the companies under contract to fly NASA’s astronauts, and examine “everything and anything that could impact safety” as the companies prepare to fly humans for the first time, William Gerstenmaier, NASA’s associate administrator for human exploration, said in an interview with The Washington Post.

    The review was prompted by the recent behavior of SpaceX’s founder, Elon Musk, according to three officials with knowledge of the probe, after he took a hit of marijuana and sipped whiskey on a podcast streamed on the Internet. That rankled some at NASA’s highest levels and prompted the agency to take a close look at the culture of the companies, the people said.

    NASA spokesman Bob Jacobs declined to comment on what prompted the review. But in a statement, he said it would “ensure the companies are meeting NASA’s requirements for workplace safety, including the adherence to a drug-free environment.”

    NASA Administrator Jim Bridenstine said in an interview that the agency wants to make sure the public has confidence in its human-spaceflight program, especially as the companies are getting closer to their first flights, scheduled for next year.

    “If I see something that’s inappropriate, the key concern to me is what is the culture that led to that inappropriateness and is NASA involved in that,” he said. “As an agency we’re not just leading ourselves, but our contractors, as well. We need to show the American public that when we put an astronaut on a rocket, they’ll be safe.”

    French auditor says Ariane 6 rocket too conventional to compete with SpaceX
    .
    France's independent state auditor, the Cour des comptes, has raised concerns about the viability of Europe's new rocket, the Ariane 6 launcher. In its 2019 annual report, the auditor said the France-based launch company Arianespace is also being too cautious as it grapples with competitors like the US-based SpaceX.

    "In 2017, Arianespace lost global leadership in the commercial market to the American company SpaceX," the report finds. "This competitor's business model is based on the breakthrough model of reusable rockets."

    The report discusses the potential for further losses of market share and revenues against the rise of competition from SpaceX....

    Europe’s Next-Generation Rocket Is Doomed Even Before First Flight, Auditor Finds
    .
    French satellite operator Arianespace has little hope of keeping up with competitors such as Elon Musk’s SpaceX.

    This is the scathing assessment of France’s independent state auditor in a report that picked apart the flawed economic model behind Ariane 6, the next generation of rocket-launchers set to start operating in 2020.

    It made the point that Europeans, who have taken part in developing the launcher, went for a “cautious” approach and invested in the kind of controlled technology that potential clients in the continent had no faith in, even back in 2014. This means that Ariane 6 is stuck in the past and “risks not being competitive over the long term.” Its U.S. rivals are way ahead and already testing future disruptive technologies.

    NASA “still working toward” 2020 launch of massive SLS rocket
    .
    NASA has continued to make progress with the development of its large Space Launch System (SLS) rocket as work continued on its critical core stage throughout the partial government shutdown, and the agency is nearing critical hardware tests. However, it now seems all but certain that NASA will miss its latest launch date for the first flight of the rocket, June 2020.

    Multiple sources have told Ars that while NASA is still targeting sometime later in 2020 for a test launch of the SLS rocket and Orion spacecraft, known as Exploration Mission-1, this flight is likely to slip into 2021.

    This week, in response to a query about potential delays, a spokeswoman for the agency's exploration program, Kathryn Hambleton, said the agency is not ready to discuss a new schedule yet. "NASA is still assessing impacts as a result of the shutdown, but we are still working toward a launch in 2020," she told Ars.

    Hardware moving

    The core stage of the rocket, consisting of a large, liquid hydrogen fuel tank, a smaller but still considerable liquid oxygen tank, and four main engines, is coming together. In January, the agency installed the large liquid hydrogen tank onto a test stand at Marshall Space Flight Center in Huntsville, Alabama for a "structural test." This tank, identical to one that will be used during a mission, will be subjected to the same stresses and loads it will endure during liftoff and flight.

    Europe unveils design of reusable rocket that looks a lot like a Falcon 9
    .
    Late last week, the European rocket maker Ariane Group and the French space agency CNES announced the creation of an "acceleration platform" to speed development of future launch vehicles. The initiative, called ArianeWorks, would be a place where "teams work together in a highly flexible environment, open to new players and internationally."

    "In this era of NewSpace and in the context of fierce competition, ArianeWorks will accelerate innovation at grassroots level, in favor of mid-tier firms and start-ups, with commitment to reducing costs a major priority," a news release sent to Ars states.

    As part of the announcement, the organizations released a promotional video for the group's first step—a so-called Themis demonstrator. The goal of this project is to build a multiple-engine first-stage rocket that launches vertically and lands near the launch site. The rocket will be powered by Europe's Prometheus engine, a reusable liquid oxygen and methane engine that may cost as little as $1 million to build.

    NASA Reassessing EM-1 Launch Date
    .
    NASA Marshall Space Flight Center (MSFC) Director Jody Singer said today that the agency is reassessing the 2020 launch readiness date for Exploration Mission-1 (EM-1), the first launch of Space Launch System (SLS) with an uncrewed Orion capsule. SLS was an excepted activity during the 35-day partial government shutdown so work did not stop and significant progress is being made, but NASA wants to ensure the system is ready before attempting the first launch.

    NASA to replace Europa Clipper instrument
    .
    NASA has removed an instrument previously selected for the Europa Clipper mission, citing cost growth, but will seek ways to replace it with a less complex design.

    In a March 5 statement, NASA said that it would no longer pursue development of the Interior Characterization of Europa Using Magnetometry (ICEMAG) instrument, a magnetometer designed to measure the magnetic field around the icy moon of Jupiter. ICEMAG was one of nine instruments originally selected by NASA in 2015 for development for the Europa Clipper mission.

    NASA said that the increasing cost of ICEMAG, still in its preliminary design phase, led to its removal from the mission. “I believe this decision was necessary as a result of continued, significant cost growth and remaining high cost risk for this investigation,” Thomas Zurbuchen, NASA associate administrator for science, said in a memo.

    SpaceX, ULA win military contracts, Air Force renames EELV program
    [In light of rocket development moving toward reusability, EELV (Evolved Expendable Launch Vehicle) program is now NSSL (National Security Space Launch) program.]
    .
    United Launch Alliance and SpaceX recently won contracts worth $739 million to send six missions into orbit for the U.S. military, and the Air Force has announced a new title for its flagship launcher program, dropping “expendable” from the name in a new era of reusable rockets.

    The contracts announced in February by the Air Force’s Space and Missile Systems Center were split between ULA and SpaceX, rivals in the U.S. launch industry. ULA won deals for up to three launches worth $441.76 million, and the Air Force awarded SpaceX contracts worth $297 million, also for three missions.

    Air Force and ULA officials confirmed to Spaceflight Now this week the configurations of the rockets assigned to the six military space missions.

    Facing more delays, NASA opens door to launching lunar mission with commercial rockets
    .
    In a major shift, NASA is considering using two commercial launchers to send an unpiloted Orion crew capsule and its European-built service module on a test flight around the moon next year, maintaining the lunar test flight’s schedule despite fresh delays in the development of the multibillion-dollar Space Launch System that jeopardize the heavy-lifter’s 2020 inaugural flight, the agency’s administrator said in a congressional hearing Wednesday.

    The lunar test flight, known as Exploration Mission-1, is a precursor to NASA’s plans to fly astronauts on the Orion spacecraft, build an outpost in lunar orbit, and eventually return humans to the moon’s surface. But Exploration Mission-1, or EM-1, has faced repeated delays as engineers build and test the Orion capsule and the Space Launch System, the heavy-lift rocket originally designed to loft Orion spaceships and astronauts into deep space for the first time since the last Apollo moon mission in 1972.
