NASA Ponders Postponing Launch until July

BitFluid writes "According to Sun-Sentinel.com, NASA is considering postponing its Return to Flight shuttle launch because of 'ongoing concern about possible ice buildup on a liquid oxygen propellant line.' Apparently, that stuff turns into debris on launch, a risk they need time to investigate. If delayed, the target launch window becomes July 13 through July 31."

      The next generation vehicle is almost guaranteed to use LOX/LH at least for its upper stage, and is essentially guaranteed to use LOX for all stages. So, solving problems related to cryogenic fuels/oxidizers is something we need to do anyways.

      These problems aren't new - they've been around ever since we started using cryogenic fuels and oxidizers. Only the concern is new. We should be very proud of the fact that NASA is putting forth the money and time to try and solve these problems; we're doing a service to every other space agency in the world, especially the ESA with their Ariane rocket system. NASA has been, especially since the collapse of the USSR, by far the most prolific developer of new technology to help increase rocket safety and reduce costs. The Russians, while they have some *great* systems, haven't been advancing tech much. While refining extant launch methods is a great solution in the short term, it's a dead-end; there's only so far you can go.

      As another poster mentioned, one big problem with the shuttle is that it's side-mounted. This being the first large-scale vehicle with a droppable tank, it's no surprise that hindsight is 20/20 on this one. The next generation will almost certainly be mounted on top. The LOX issue, however, is not likely related to this - this is about preventing ice formation on the LOX lines (they didn't state which ones), not the tank itself.

      There are other issues that were discovered as well as we tested the Shuttle. For example, the asymmetry of the shuttle led to the main structural support being on the underside of the shuttle. However, the SSMEs are mounted to the center of the backside. The net result is that you get a stronger vibrational load than on most past rockets. Again, hindsight is 20/20.

      The shuttle has been a *great* learning experience. So much new tech has been developed in the process, which will really help bring down costs and increase safety of the next generation vehicle. And we do need to move to that next-gen vehicle, and they are moving to it (the CEV). But until then, this is what we've got. And there are no "replacements" for the shuttle out in the present day. Nothing can do it's scale of cargo return, and only unmanned vehicles can do its scale of cargo launch. However, unmanned cargo launch still is having trouble docking, as we saw with Dart. So we need to use the shuttle for a bit longer, and we might as well use this as an opportunity to solve universal technical challenges.

      If you are referring to the CEV its not a few years, its more like a decade. The only thing happening in a few years, maybe, is a test flight by the two teams of an unmanned tin can maybe in 2008 but it would be a miracle if they held that schedule, this is NASA, Boeing and Lockheed after all. The earliest there would be a manned flight is 2014 and that is pretty much a fantasy target.

      Here is a biting editorial on the giant mound of contractor pork and red tape that is CEV. Transformational Space, the one fresh and innovative company in the early running, apparently pretty much abandoned bidding on it when they saw it was business as usual for NASA and structured so only Boeing and Lockheed could or would compete for it.

      Even if a manned CEV ever flies which is a long shot given NASA's record with new manned vehicles since the shuttle, you are probably talking about a relatively tiny conical capsule, yes after a decade of new development and billions of dollars you are going to pretty much be back where we were in the 1960's, a tiny vehicle capable of carrying a few people and a tiny amount of cargo. The launch vehicle will be a derivative of existing expendable launchers and wont have anything close to the power of a Saturn V so every mission profile beyond putting a tin can in LEO requires multiple launches and docking all the pieces in orbit.

You'll never hear any rocket fanboys/girls on slashdot cheering for them, though, because they're not joyrides, and because they actually can get to orbit, they actually cost more than the 100k-200k$/seat on SS1.

      So many people here have no concept of the technological difference between orbital and suborbital, and think that the real challenge is in strapping a cockpit into the craft (which is little more than what aircraft builders - including Rutan himself - do all the time). Quite unfortunate, really. You can get a "rocket engine" like used in SS1 for cheap. If you want enough ISP and a low enough tank mass to get to orbit without a preposterous scaling factor, however, you need a *real* rocket engine with compressors (at least one for each line, probably two for each line if you want good performance), with parts made of superalloys and/or with an elaborate regenerative cooling system, etc. Such a rocket engine, produced not by mass manufacturing, makes your average million-dollar-or-more mass-produced jet engine look like a child's toy by comparison - and yet people here seem to expect them to cost pennies.

      The difference between an orbital and suborbital craft is like the difference between a golf cart and a formula-one racer. The difference between an unmanned craft and a manned craft is like the difference between a golf cart and an enclosed golf cart. A cockpit is not a major technical challenge even close to the scale of the orbital vs. suborbital technical problems.

      You do realize the SatV was not a LEO launch craft, right? If used in LEO mode and all three stages the SatV could put 130 tons of *payload* in orbit. The shuttle can not do that. Weight-wise the SatV could put the shuttle in orbit. With payload.

      The Shuttle can put a mere 24 tons of payload into LEO (Columbia was higher but they lowered it). That is within the (estimated) range of the Atlas V heavy. It is also within the range of the Delta IV Heavy.

      Do you not also realize a SatV powered launch will put a crew of 4-6 on Mars for two years in a sizable hab?

      IIRC, the science lab proposed for ISS (Italian?) was 26 tons which actually puts it out of the Shuttle's official limits.

      You don't *need* to replace a 25 tons to LEO payload capacity craft with one that can put 125 tons of payload to LEO.

      On the other hand, a SatV lift capability could likely launch several modules for the ISS if you could get the positioning and balance right.

      so every mission profile beyond putting a tin can in LEO requires multiple launches and docking all the pieces in orbit.

      You do realize that is what the Shuttle does regarding ISS, right? We put a "tin can" into orbit and then hook them up. ISS is taking, and was always designed to take, multiple launches and on-orbit assembly.

      Further, the Shuttle limits the diameter of cargo to 4 meters. SatV had a 10 meter capability.
      http://www.answers.com/topic/saturn-v

      Both the Atlas V heavy and the Delta IV heavy have diameters of 5 meters. Even the Atlas V (non-heavy) can lift approximately as much as the Shuttle to LEO and has a meter on it in diamter as well. The Atlas V is a current model.

      Also, the ISS was never designed to be built using only the shuttle. Of the 50 initially determined flights, only 39 were shuttle flights.

      The high-side estimates for re-developing the SatV for today's use is in the range of 1.5-2.25 billion dollars. That is less than the MSL will cost. That is less than the cost of say 4-6 launches of the shuttle. A seat of the pants guesstimate is that a single SatV ISS lift launch would be able to replace a minimum of four modules. With crew. so if the cost to the first launch of a new SatV was 3 million the first launch of four ISS modules would replace 4 Shuttle launches at an estimated cost of about 1.6 to 2 billion dollars. That means if you then launch another set of 4 modules, you just came out ahead, as the subsequent launches don't cost the full redevelopment costs.

      That said, just because the ISS has turned out the be the collossal money pit/failure many of us knew it was destined to be is no reason to throw good money after bad. Most other nations invovled in it would actually love it if it was cancelled. Some can't seem to meet their end of the deal.

    1) The tank has all 4 LH2 sensors that were failing intermittently. They showed dry when the the tank was full, and wet when the tank was empty... not a good thing!

    2) The diffuser in the LH2 tank is all wrong! Marshall switched a vendor and passed on a whole new part to the Lockheed ET guys at Michoud, and no one bothered to qualify it. During tanking test, this diffuser had a higher delta p across it than nominal. What effect could this have? We don't know.

There was a "low-tech" solution that was being tried out: flash huge parabolic lights on the area, which worked out great for the parts that were in direct exposure to light, but you can't get a direct line of sight from the ground to a large part of the bellows. Consequently, more ice formed than we expected around areas where foam was removed due to debris concerns. Other options are being explored.

    All of this information was available this morning during the NASA press conference with Michael Griffin, and then the Technical Conference with Bill Parsons and Wayne Hale. If anyone here actually cared, they could have gotten their facts straight by watching it or reading the transcripts.

    NASA is making the right choice... the tanking test was supposed to make us certain we are ready to fly, and we see that there's a few remaining questions (i.e. the three above).
