    “To accomplish Dawn’s journey into the heart of the asteroid belt, a space ship, one whose engine will work without fail for years at a time, is required. Dawn’s remarkable ion engines employ electrical currents, magnetic fields and xenon. The high tech innards of an ion engine change the xenon into a positively-charged plasma and accelerate it out the engine at speeds over 78-thousand miles per hour,” said Nimoy.

    “A mission into our distant past, a mission for the future, a mission into the heart of the asteroid belt, a mission called Dawn.”

    And you know what?

    THIS IS ANOTHER TECHNOLOGY STAR TREK PREDICTED!

    Captain Ransom used this technology in Voyager.

    Sorry for the shouting, but I just love it when I see Star Trek predict and inspire technology.

    That's one of the things that science fiction is eggsellent at.

    Get's me all hot and bothered.

    Quote:

    Yep… the beta-emitter is particularly nice in a way … except that its also likely to cause neutralization of the very ion stream that we're trying to deflect. This is not to say that having a big fat, concentrated beta emitter at the center isn't a good solution! In fact, it needs only be open at one end (the forward end!) in order to do its job. The betas going backward could be intercepted by phosphors and provide substantial electricity. You know, "betavoltaic" 2 birds, one stone.

    (hmmm… thinking)

    Beta sources are actually pains in the patood: essentially they are only surface emitters. Get a block of the stuff, and all those cute lil' electrons get caught by the material, and never escape. Maybe this isn't a bug, but a feature! Creating betavoltaic panels, PV cells on the sun-side pointing both at the sun (why not?) and on the other side, away from it, but coated with phosphor, the beta emitter, thick enough to be both an optical reflector (redirecting the phosphor-light toward the PV cells) and emitting electrons furiously in the wrong direction (but right to create a positive-charged space ship)…

    Wow. What a concept. Kind of a nuclear-powered space vehicle.

    Actually, one could also just collect the wrong-way electrons too. We've discussed this before: when a sufficiently negative (hundreds of kV) potential exists between a beta-emitter and a collection plate, the betas are decelerated efficiently, and slam into the plate at much lower kinetic energy (voltage). In so doing, they're efficiently transformed from high energy particles to lower energy, while bolstering the high e-field. Tapped away through high-voltage switching, and then transformers, they easily can be converted at high efficiency to a torrent of much lower voltage, much more copious electron flow … suitable for the spacecraft's electrical system.

    Another nuclear win.

    SLS News:
    New SSME class engines
    http://www.nasa.gov/exploration/sys...-25-joins-the-space-launch-system-family.html

    Some comments from Nasaspaceflight

    A higher head pressure implies that the boost pumps would need slightly less work to perform in order to get the output pressure to be the same, so there might be a very small, perhaps negligible, increase in performance. In any case, the engines are going to be operated at a higher thrust level compared to shuttle, at 109% (111% for new RS-25s) compared to 104% for the Space Shuttle.

    « Last Edit: 01/23/2015 06:25 AM by Steven Pietrobon »

    SLS also be experiencing greater G loading(3.3g) during ascent than STS(3 g) did, which in effect increases head pressure even more.

    The problems with space elevators

    [1] power - inability to deliver 15 kWh/kg for each kg of mass, which includes payload, shell, life support, tractors, etc.

    [2] centripetal forces - management of the tendency of a supported mass to exert a tangential force due to its increasing (accelerating) lateral velocity. Akin (closely) to Coriolis forces.

    [3] material inhomogeniety - the statistical inability to produce masses of the material to better than 1 ppt (part per trillion) homogeneity and freedom from lattice dislocations. Anything above that, and the dislocations become nuclei for fabric ripping. Which is bad.

    [4] material mass - 100% of the 'solutions' require a doubly tapered ribbon cross section. More "up there" than "down here". fatter cable to support the hung mass. So, even if a 1 dm wide, 1 cm thick cable might theoretically have the strength, the excess strength (for the payload pods), the durability and so on, "up there" it would need to be 1 m wide, and 1 dm thick. 100× the cross-section. That's a lot of stuff. And don't forget that the counterweight needs to be a significant fraction farther than the 22,000 miles to the geosynchronous point. More like 40,000 miles (65,000 km). Anyway… 800,000,000 kg of material at 0.75 kg/L

    [5] bonding & protection Of course … it also needs to be woven/bonded, enshrouded with a tough, non-conductive electrostatic/friction layer. Has to be mighty thin. The counterweight would need to be over 200,000,000 kg.

    [6] deployment … is a clearly very difficult problem, vexed by all nature of Coriolis forces, centripetal issues, conductivity gotchas, and more. EVEN if the material were available from a space-based magic Alien device that just squirted out the stuff in tons-per-day … this is still a huge problem.

    [7] resilience … said cable has to be able to handle everything Mother Nature can throw at it. Weather is the least of its problems down here in the troposphere. Lightning … is a biggie - especially since it gets well into and beyond the ionosphere.

    [8] repairability - the most overlooked issue by far: so, the constant cable-scanners detect flaws that soon would result in a cable break. How to "fix it"? No one knows. Perhaps if the cable were more of a chain-of-replaceable segments, then they could be substituted out. Latch onto, snip out the bad stuff, put the new one in, gradually "let go" and see if it works.

    This is what will limit this in our lifetime. I simply doubt that we'll be able to make near 1,000,000,000 kg of atomically thin monolayer graphene. AND somehow get it up to space.

    There are even more issues, but they pale into comparison to this.

    Worked examples, physically smaller and less massive than those suggested so far, range from a 1kg payload launched to 10\% of the speed of light by a transmitter only 25 times the mass of ISS, to a larger system that can launch a 1000 kg payload to 50\% of the speed of light.

    From Mark Wade

    The basic saucer shape was very unstable. This of course made it extremely maneuverable. But the modified blunt lenticular shape developed for Pye Wacket had sufficient stability to be controllable by aft control rockets and still possess maneuverability greater than that of conventional designs.

    SLS capabilities:

    Alan Stern, who led the hugely successful New Horizons mission to Pluto, chimed in with other things SLS could unlock:

    "When you want to do orbiters and landers and ambitious missions that have been spoken about, you need to carry a lot of fuel, and there's no way to lighten the fuel, you need it so you can come to a stop on that planetary surface or in orbit, and SLS is really going to help us enable those kinds of deep space missions, including I hope someday a return to the Pluto system in the Kuiper Belt," Stern said.

    Even though New Horizons launched on the most powerful Atlas V rocket, built by United Launch Alliance in Decatur, Alabama, it still took nearly ten years to simply fly by Pluto. It was also such a lightweight spacecraft, the Atlas V might as well have launched empty.

    From:

    http://www.waaytv.com/space_alabama/nasa-s-space-launch-system-can-do-more-than-human/article_bdcfa972-37c9-11e5-a8fe-832b6ef57ee7.html?utm_source=Today%27s+Deep+Space+Extra%2C+Monday%2C+August+3%2C2015&utm_campaign=dailycsextra&utm_medium=email

    Also:

    SLS could also aid deep-space astronomy, by allowing larger and more powerful[​IMG] space telescopes to be launched, Grunsfeld said. The rocket could launch entire space observatories, or perhaps "parts that astronauts could assemble to build a telescope that could search for atmospheres around nearby [alien] worlds," Grunsfeld said.

    The 535 second long test firing of the RS-25 development engine was conducted on the A-1 test stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi – and ran for the planned full duration of nearly 9 minutes, matching the time they will fire during an actual SLS launch.
    All indications are that the hot fire test apparently went off without a hitch...

    Some quotes from Nasaspaceflight that should be of interest to SLS detractors

    Just to add a little more from that discussion. Another factor was that for an EELV class launch a spacecraft bound for Europa would need at least one Venus flyby. That would mean added thermal shielding and control. It has been done in the past with Cassini and Galileo. Making a spacecraft that will spend most of its life in the the cold outer solar system able to hang out that close to the sun introduced design complexity and cost. A spacecraft near Venus would get almost twice the solar heat as one near Earth, and 52 times what it would receive at Jupiter.

    Solar Probe Plus is $389 million...http://solarprobe.jhuapl.edu/

    And even with a Delta 4-Heavy launch the mission will need seven flybys of Venus!?!

    No limit to the size of solids?

    "By 1966, NASA officials were looking ahead already to sizes as large as 600 inches, noting that "there is no fundamental reason to expect that motors 50 feet in diameter could not be made" [Astronautics & Aeronautics, January 1966, p. 33; NASA budget data, February 1970]."
