The Apollo program ran for 12 years and ended with six successful missions. Here we are half a century later, with wildly more advanced technology, a bunch of ready-to-fly rockets to choose from, and they need another ten years for a single mission? What “organizational changes” are necessary that cost billions?

I think I read somewhere that we actually lost the technology to build the Saturn V; the fab tools, the blueprints, and the skilled labor isn’t there anymore. It’s like Damascus steel or Roman concrete or Greek fire. We may have to reinvent it.

  To be honest I don’t know enough about this, but my understanding was that both the Delta IV Heavy and Falcon Heavy have the ability to execute a moon mission, plus the Boeing SLS is already in development. Is there a need to start from scratch?
  - nradov 7y ago
    No one had proposed starting from scratch and building new Saturn V's. That would be totally impractical. But none of those new rockets have actually demonstrated the ability to lift enough payload for a manned lunar mission. They might be able to do so eventually but years of development work remain.

    Maybe if you're willing to do multiple launches and Earth-orbit rendezvous.

  It would be very difficult to build a new Saturn V just because any product of any complexity is inherently embedded in the economic ecosystem it came from. If the plans specify a #5 Widget and nobody has made a #5 Widget in the past 30 years, then you’re kind of stuck even if the vastly superior #8 Widget is currently available in any hardware store. What you say is true but it’s not correct to frame is as a step backwards as is often done. The Saturn V would be hard to build today because technology has moved forward a great deal. This is an important distinction because it means that building a new rocket with the capabilities of the Saturn V is still very much possible. SLS and Super Heavy are two rockets in active development that will exceed the Saturn V. SLS is taking forever but that’s just a matter of not putting resources into it. It’s expensive, but Saturn V was too. Super Heavy is a little more speculative but it looks promising and its capabilities will blow Saturn V’s out of the water if it actually flies, and for far less money.

    EDITED The Constellation program cost $12B between 2005-2009 [1] and includes Ares V, an earlier version of SLS (but also Orion and Ares I). SLS under the current name (without Orion) has cost $14B 2011-2018 [2]. No idea about 2009-2011. It will cost several billion per year until it is cancelled. It uses existing (flown in space) shuttle engines, shuttle main tank tooling, 5 segment version of shuttle's 4 segment boosters (also 15 years in development), etc. It requires no new technology and it is not trying to be better than anything. It has all the money it wants. They even took money away from commercial crew to pay SLS, a few years ago, which made commercial crew late which forced them to pay more to the Russians. The problem with SLS is that it is designed to burn money. It is not designed to fly, to achieve a mission of any kind. It is optimized to cost as much as possible, because its success is defined as "raised average wage in my congressional district for as long as possible" by the people who ordered it done. 1 - http://www.planetary.org/blogs/jason-davis/2016/20160801-horizon-goal-part-2.html http://www.planetary.org/blogs/jason-davis/2016/20160801-hor... 2 - https://en.wikipedia.org/wiki/Space_Launch_System#Funding_history_and_planning https://en.wikipedia.org/wiki/Space_Launch_System#Funding_hi...

There's a lot more complexity in this project and less relative budget. There's also not the same level of pressure aid space race happening.

A polite critique: Six successful missions which landed, yes. I'd argue 10 successful missions in total. Excluding Apollo 1 and 13, there were four additional missions which were never tasked with landing on The Moon; I would argue that those can be considered successful as well. [Edit]: Changed "with landing" to "with landing on The Moon"

  For reference, here's what each mission did: Apollo 1: Burned on the launchpad, killing Gus Grissom, Ed White, and Roger Chaffee. Apollo 4-6: unmanned missions Apollo 7: Flew in Earth orbit and tested the command module (the lunar module wasn't ready yet). Apollo 8: Orbited the moon, further testing the command module and scoping out a potential landing spot. Apollo 9: Flew in Earth orbit, testing rendezvous between the lunar module and command module. Apollo 10: Dress rehearsal of the moon landing, except they didn't land. Came withing 50k feet of the surface. Apollo 11: The first moon landing. Only went outside for less than 3 hours. Landed 4 miles away from the target. Apollo 12: Second moon landing. Two 4 hour walks outside. Landed very close to the target. Apollo 13: Oxygen tank exploded in command module on the way to the moon. Used the lunar module as a lifeboat, slingshotting around the moon before returning to Earth. Apollo 14: Apollo 13, but successful. Did two 8 hour walks. Apollo 15: Upgraded lunar module that could carry the rover and additional supplies, and new suits that they could take off inside the lunar module (previous missions only took off the helmet and gloves). Three 8 hour stints outside, venturing tens of miles away from the lander, including up the side of a mountain. Focus of the mission was entirely on science and collecting samples. Apollo 16-17: Apollo 15, but at different places and more extreme. --- I'm almost finished listening to "A Man on the Moon" by Andrew Chaikin that tells the story of each mission. Highly recommended.

Our computers are a thousand times faster but our steel isn't a thousand times stronger and our rocket fuel doesn't have a thousand times the specific impulse. As far as cost and ultimate physical mission limitations go, we're very much still living in the same neighborhood as 1970.

  Advances in ground computers do not translate to space computers. Most space-qualified processors are still on the order of tens to hundreds of MHz. I currently work on a space science satellite launched in 2015 for NASA and our flight processor is 40 MHz. https://www.geek.com/chips/nasas-orion-spacecraft-runs-on-a-12-year-old-single-core-processor-from-the-ibook-g3-1611132/ https://www.geek.com/chips/nasas-orion-spacecraft-runs-on-a-...

    Current space-rated FPGAs are like 10-15 years out of date compared to what the newest stuff can do. People are starting to take more risk with launching commercial parts in LEO but no one is seriously going to rely on anything but Level 1 parts for expensive, long-term missions.

    I didn't mean it that way, sorry. People at NASA are still extraordinarily smart. The number of those smart people is different. NASA right now has approx direct 17k employees and approx 60k contractors. Back in the times of the Apollo program, there were 36k direct employees at NASA with > 350k contractors. See Figure 1-4 in this PDF: https://history.nasa.gov/SP-4012v1.pdf#page=15 https://history.nasa.gov/SP-4012v1.pdf#page=15 Also, it seems to me that NASA is involved in far more programs right now than it was back in the times of the Apollo program. Which isn't a bad thing in itself, but of course each program itself has smaller scope.
    - craftyguy 7y ago
      They are involved in far more programs than they were during the Apollo era. I'd much rather see NASA stay involved in these other areas (e.g. planetary sciences/exploration) than throw everything into a manned mission to the moon to 'make merica great again' a la 1960s style.
      - jvanderbot 7y ago
        I agree with the fact that we are spreading bucks over more planets. I'd love to see a concerted incestment in a consistent strategic direction with a tangible milestone. But at the same time, there's lots of exciting stuff going on.
jvanderbot 7y ago
Well, for one, there's no more apollo program to build onto? So, such a pipeline should be restarted? Ten years is about the timeline to expect commercial launches / lifts to the moon. I suspect to be cost effective, NASA is synchronizing with commercial partners and standardizing mission architectures to ensure a long line of lunar missions. (source: Working on a related problem). From the NASA Page: "CLPS contracts are indefinite delivery, indefinite quantity contracts with a cumulative maximum contract value of $2.6 billion during the next 10 years." So there's your new apollo program. 10 years and billions of investment, but with commercial taxis rather than NASA-built. While I'm on the subject of NASA + Commercial partners. Imagine you had to build your own car to get to work every day, and suddenly a taxi service starts up. Would you use the taxi instead? That's the analogy for SpaceX, Blue origin, etc. Most programs are about science and human exploration, which involve significantly more than rocket and faring technologies. Moving beyond those expensive development projects can only make NASA-led initiatives more cost effective. It's how it has to be nowadays.

It has been close to 8 years since the United States launched crew on one of her own launch vehicles. Currently, we have no man rated launch vehicle and have to rely on the Russians to launch people to the ISS. Spaceflight is altogether more complex than you think.
