Astronauts Won't Be Flying To Space In Boeing's Starliner Until 2018 (theverge.com)

An anonymous reader writes: The Boeing Starliner, one of two new spacecraft meant to break the Russian stranglehold on sending people to orbit, has hit a snag. Originally scheduled to start flying next year, the Starliner won't carry a crewed mission to the International Space Station until 2018 at the earliest. Six years is long enough. Ever since the 2011 retirement of the space shuttle NASA has been pushing for privately built craft capable of ferrying astronauts to orbit, which would let the agency buy American-made ships and end its dependency on renting seats aboard Russian spacecraft. The Starliner and SpaceX's Dragon were chosen, and 2017 was to be the year. But while SpaceX has sent its ship to the ISS on multiple uncrewed cargo resupply missions, the Starliner won't make such trips until 2017 and won't carry people until 2018 at the earliest. SpaceX maintains that it will be able to send crews to orbit in 2017.GeekWire explains: "For Boeing to shift its crewed test flight from 2017 to 2018 isn't as much of a slip as it might sound: The company's earlier schedule had called for the visit to the space station to take place in mid-December."

      A falcon 9 costs ~$60M/vehicle, the same price as a B737. Their complexity is roughly the same and BA builds 50 737s/month.

      The cost of building the rocket is only about 60% of their total launch costs. Hence why the planned discount for reuse is only about 30%.

      Unfortunately, the engineering I have seen you talk about for Venus, some of it would be utterly useless in space, so would be less useful to your idea of a Venus mission. However, if we can learn how to keep people breathing long term without adding oxygen into the system, and work out how to grow food and feed a space station, these things might translate pretty well into an initial Venus mission that might test out the acid breakdown process I have seen you talk about previously, while still able to run a mission without the input if it doesn't work.

      Most of the cost of developing for Venus is directly applicable to elsewhere. The interplanetary transfer stage, for example - one of if not the most expensive component to develop - would be pretty much identical to that used for Mars. The basic starting resource extraction trees are quite different for both bodies (generally easier on Venus), but after that, they merge together - same process for the Sabatier reaction, for UHMWPE synthesis, for Haber, for Ostwald, etc. Everything related to "long-term human habitation far from Earth" applies to them both, from medicine to livestock, from birth control to toilet paper. There's a huge amount of things that you need for anywhere you might want to live long-term. Superlight collapsible ovens/microwaves and refrigerators. Ultracompact, efficient cryogenic refrigeration systems (ex. magnetocaloric). Lightweight/metal-free wiring possibilities, like CurTran's CNT "LiteWire". The list is thousands of entries long.

      Yes, Venus and Martian habitats are very different structures, and the starts of their resource production trees very different. And Mars presents many extra challenges that Venus does not, while Venus presents some that Mars does not. But both share a tremendous amount of heritage.

      As for ISRU proof-of-concept on Venus, that requires a probe. Such a mission could be funded today at little cost if there was will for it. Maybe even Discovery-class. The same mission could likewise do a ballute-entry test, even if relying on helium as a secondary inflation gas, and significantly advance the TRL on that.

      Of course, there's a great deal more data gathering and testing than just those things that needs to be done before a manned mission could be launched. You need much better gas/mist analysis, better turbulence modeling, an actual understanding of Venus lightning (more than "it exists, at some unknown layer of the planet, at some times for unknown reasons", which is basically our understanding right now), better materials tolerance data, better precipitation / condensation data, etc. There's a number of missions in the pipes for these sorts of things, although it depends on where the funding goes. On Earth you need to make a reduced-scale demonstrator and actually fly it for long periods (at least several months), using heliox rather than normal air - first unmanned, then manned. You also need to launch a demonstrator into a reentry trajectory to test the full-scale deployment. Thankfully, Earth's and Venus's outer atmospheres and gravity are so similar that it makes this sort of testing easy.

      Neither a Venus nor Mars mission are just around the corner. IRSU is also exceedingly important to Mars missions, and we're just barely getting started with that as well. But it's harder to do. I was just reading a paper the other day on the current prospects for local water production, of the five different techniques they're looking at (plus many more that they had to simply rule out), none have any maturity whatsoever, nor have appropriate reserves for them been found and quantified. Like Venus, it's a case of "we know how to do it, from a technical level". Like Venus, the hardware doesn't yet exist, but we know a general path we'd take to build it. But unlike Venus, consistently sourcing process-effective raw materials is far more challenging. Glaciers are usually under too much overburden for strip mining, and in-situ extraction is in an exceedingly early stage at this point. In-situ mining poses the risk of collapse pits forming underneath / near the miner, while strip mining leads to sublimation. The glaciers are believed to generally be full of some unknown mixture of rock and sand of unknown, inconsistent qualities. Much of the solid ice is brine. All of the ice is expected to contain dust, which on Mars is toxic, and contains compounds like perchlorates that are prone to messing up RO membranes even after distillation.

On another related (but non-space) set of actions, Northrop was allowed to gobble-up Grumman and become NorthropGrumman.

    In doing so, the government made itself almost entirely dependent upon three big defense firms, two of which dropped most commercial products and therefore became dependent on military contracts. Now the government pays these big boys as much as they demand for stuff out of fear that by not doing so we might los one of the three and thereby lose a vital strategic capability. This massive corruption served the shareholders of these firms very well, and the members of congress who get campaign funds very well, and members of several administrations of both parties very well (who moved through revolving doors between government and contractor jobs). The taxpayer is the loser.

    These three firms have become so fat, dumb & happy that they are no longer used to having to compete, having to control costs, having to deliver on time, or having to deliver products that actually perform as promised (Adam Smith could have easily predicted this natural consequence). The result is a pile of grossly-overpriced incompetence. Boeing started working on the "Starliner" (albeit under a different name) when Bill Clinton was in the White House in the 1990s as part of a project to replace the shuttles. They dusted-off the same Apollo-based design as a bid for the "CEV" of the George W Bush admin post-Columbia disaster "Constellation" project (they lost the bid to Lockheed for what was named "Orion" then renamed "MPCV" by Obama, and then re-renamed "MPCV Orion"). When the Obama admin extended the Bush "commercial cargo" program to "commercial crew" Boeing dusted-off their Apollo-derivative again and this time called it "CST-100 Starliner". Here they are, 20+ years after starting, and 12 years after re-restarting, and 6 years after re-re-restarting the effort to make an improved 1960s Apollo capsule (where the mechanics and aerodynamics were already well understood) and they are slipping schedules and will provide a capsule ultimately far less capable than the one Armstrong, Aldrin and Collins took to the Moon in 1969. (The Apollo could seat 6 in rescue mode to LEO and was configured but not flown that way once during Skylab, and as normally configured could do Moon missions, whereas Starliner is LEO-only and only supports a crew for a few hours in Earth orbit with its only advance being the ability to hibernate at ISS for months)

    There's no surprise here. Monopolies serve shareholders and sometimes serve certain interests in government, but NEVER the general public or the taxpayer. This is not a Boeing-only issue: LockMart has spent billions and over a decade on Orion (their Apollo capsule recreation) and will not be ready to put people into it until about 2023. Meanwhile, their F-35 is the most expensive warplane program in world history, while being far behind schedule and severely under performing.

    Bush cancelled shuttle, but with a concrete plan for the replacement and actual metal being bent. The Constellation program was underway and without a big funding increase from congress, it was thought that the money saved by no longer flying shuttles would speed-up the replacement making the gap in US manned spaceflight capability shorter than the post-Apollo gap before Shuttles (undesirable, but manageable and not unprecedented).

    When Obama entered office, shuttles were still flying and the program was not irreversibly doomed. Some vendors had halted spare parts production, and in 2009 NASA determined that it could un-cancel the program with only a minor disruption (either a gap of about a year waiting for parts, or no gap with a slight spacing-out of scheduled flights). As the plans were studied more seriously, they appeared to concentrate on retiring one orbiter and using it as a source of spare parts while awaiting re-start/re-cert of the affected suppliers. There was even consideration of shifting the orbiters to a vendor like ULA for commercial ops, and there were no "showstoppers".

    What ended all the consideration for un-cancelling the shuttle program was the Obama administration 2010 NASA budget proposal which cancelled all US manned spaceflight. Congress panicked and rejected the proposal and then ordered Obama, by law, to build SLS and Orion. The Obama administration, eager to preclude any other "meddling" ordered the demolition of various shuttle facilities, the firing of many shuttle workers, and the crippling of the orbiters (all of which had their engines removed and replaced with dummies, large sections of the aft-bay fuel and oxidizer plumbing chopped out, and their OMS pods and forward RCS bays stripped and made non-functional). After the orbiters themselves had their guts ripped out, they were only useful as museum displays and it would be cheaper to build new ones.

    Bush43 scheduled the end of the shuttle program in a classic "bird in the hand vs two in the bush" error, but Obama was the eager and forceful executioner, while the executive branch OMB, which has always been an agency that wanted to gut NASA as a money-saving action, was there as a bi-partisan wormtongue (LoTR reference) cheerleader and encourager.
