  • Super-Heavy launchers and space science

    The convention thinking rap on Falcon Heavy, BFR, New Glenn and New Armstrong, Vulcan etc. has been "Why so large? There aren't any payloads that big!. Unnecessary!!"

    Apparently the science community has been paying attention to the development of these super-heavy launchers, and is thinking about those big payloads.

    BTW: KSC and Space Florida's Master Plan has been updated with a SpaceX BFR/BFS factory, a new launch complex for Blue Origin's New Armstrong (another BFR), and a small launcher complex for launchers like Rocket Lab's Electron.

    With successful test fire, massive Falcon Heavy rocket is poised to boost space science

    SpaceX CEO Elon Musk has said he'll consider it a win if his enormous new Falcon Heavy rocket even escapes the launch pad. Today, the rocket fired its engines in a test at the Kennedy Space Center in Florida, clearing the way for an inaugural launch in the coming weeks. Space scientists will be rooting for it, too. With its heavy-lift capability, the rocket can fling larger probes to distant planets more quicklyand, perhaps, more cheaplythan previous rockets.

    "We can think about follow-up missions across the outer solar system, Mars sample return, even missions to Venus or Mercury," says planetary scientist Alan Stern of the Southwest Research Institute in Boulder, Colorado,

    ...It says a Falcon Heavy launch will start at a mere $90 million, less than 20% of the Delta IV Heavy's cost.

    Such price tags could transform mission planning for NASA and other space agencies, Stern says. "You're talking about savings of hundreds of millions of dollars, which is sufficient to create whole new missions just from the savings."

    Other possible targets for Falcon Heavy include Saturn's moons Titan and Enceladus and the ice giants Neptune and Uranus. Stern, who leads a NASA mission that flew past Pluto in 2015, says teams are considering using the rocket to send a probe with enough fuel to slow down and orbit the distant world. SpaceX has said that Falcon Heavy could deliver 2 to 4 tons to the surface of Marsopening the way to more ambitious missions than the 1-ton Curiosity rover.

    Astronomers are also thinking about what heavy lift can do for them. Each component of NASA's upcoming 6.2-ton James Webb Space Telescope, with a 6.5-meter mirror, had to be both lightweight and yet hardy enough to withstand rigorous shaking during launch, two often incompatible requirements. With Falcon Heavy's additional lift, researchers planning the Large UV Optical Infrared Surveyor telescope, a proposed mission for the 2020s with a mirror at least 9 meters across, could focus less on reducing weight and more on delivering a great scientific instrument, says Matt Mountain, president of the Association of Universities for Research in Astronomy in Washington, D.C. "If we don't have to fight for mass, the testing is greatly simplified and you can launch more ambitious systems."

    SpaceX's big rocket will face competition in the coming years, and not just from the SLS. Another private company, Blue Origin, intends to debut its reusable New Glenn rocket in 2020, and ULA is working on a vehicle called Vulcan. The competition could lower prices for researchers, says Phil Larson, an aerospace expert at the University of Colorado in Boulder and a former communications director at SpaceX. "You could see not just governments having space programs, but private entities doing more in space, and maybe universities," he says.
