NASA Optimistic About Fuel Tank Repairs

DarkNemesis618 writes "NASA is now optimistic Atlantis' fuel tank will be able to be repaired in Florida. Due to a freak hail storm February 26 that had golf-sized hail chunks raining down on the launchpad put several thousand dings in the foam covering the external fuel tank as well as damaging 28 tiles on Atlantis' wing. 20 of the 28 tiles have been repaired and workers have started sanding down the damaged area of the tank itself. After it was decided that Atlantis needed to return to the VAB, NASA was unsure as to whether or not the tank could be repaired. But after bringing it back and doing more extensive inspections, the tank appeared to be in good enough shape that repairs could be done on the spot and a replacement was not necessary. This will allow for Atlantis to be launched late April for its construction mission to the ISS as well as not interfering with the remaining 4 launches planned this year. If the tank needed to be replaced, Atlantis would not have launched until June at the earliest."

      Like they said, Endeavour's (STS-118) tank would have been used if repair wasn't an option. This tank is scheduled to be completed and arriving at KSC April 12th. By replacing the tank, the remaining 4 launches this year would be pushed back. That's obviously not the preferred option as it would add more complications, but it would have been done should the damage have warranted it. Something else to note is that if they would have needed to replace Atlantis' tank, the tank would have been sent back to the manufacturer, completely repaired there and sent back for use on a later mission. The biggest issue really was whether the VAB and KSC had the ability to repair it on site or not. Luckily for NASA, it can be repaired in the VAB. This is not the first time a shuttle's tank has been damaged by hail, and let's not forget the woodpeckers who somehow thought the fuel tank woulda made a good home. (Both times the stack had been rolled back, repaired, and eventually successfully launched) Now NASA can launch Atlantis late April rather than having to wait til June if replacement was deemed neccessary.

      1: About as far south as you can easily get on the continental US, to get speed benefit out of the Earth's rotation. None at the poles, about 1000mph at the equator, IIRC about 800mph at KSC. That's why the French and British launch at the north end of South America, and why HG Wells launched from Stone Hill in Florida, not that far from KSC, in "From Earth to the Moon." It's also part of why Russian rockets tend to be such workhorses - they're equatorially disadvantaged, and even at that Baikanaur isn't in Russia, I believe it's in one of the 'stans.

      2: Before it was KSC, they were having a lot of bad days trying to launch unmanned rockets. It was really handy having lots of ocean downrange, rather than risk having their problems fall on populated areas. Maybe they are reliable enough to launch from the west today, but that's not where they started and grew.

      As an aside to both points, it's worth noting that Vandenberg, the former second Shuttle launch site is rather in the middle of nowhere. The fact that Vandenberg is further north than KSC also drove the design of the Shuttle into bad directions, according to some. I once read that the possibility of Vandenberg operation is what drove the large delta wings, rather than something simpler and lighter that could have been used for Florida/Edwards. In that context, there were some NASA types really upset that the Air Force drove the Shuttle design in a direction that they didn't want, where it is today. THEN the Air Force turned around and decided they didn't like it, after having (according to some) sabotaged its design.

No, they re-grounded the fleet and made more modifications to the tank, bringing about the one currently in use.

      The ISS was developed jointly by all of those organizations and others, and was built jointly as well. The shuttle's remote manipulator arm was built by the Canadian Space Sgency, IIRC. As for shuttles, the Russian (nay, Soviet) space agency studied the concept of building a reusable space plane, built one, and scrapped it after only a single flight. I suspect that they realized how poor the reusability of the design was, then concluded that it wasn't worth the trouble.

      The shuttle was a classic example of "too many cooks" syndrome. The military's insistence on carrying home satellites (AFAIK, never used during reentry for anything other than Spacelab, which, BTW, was designed by the ESA), coupled with NASA's insistence on maximum reusability resulted in a shuttle in which the orbiter main engines still require a complete tear down between launches, the heat tiles require massive service for every launch, and the external tank still burns up. If someone were designing the shuttle today, it would look very different. It would be at the top of the stack, the orbiter would have no main engines internally, and would be orders of magnitude safer as a result of either one of those changes.

      A shuttle designed today would not be built using steel frames, but would instead be built using more modern materials like carbon-fiber-reinforced plastic, polycarbonate, etc. except for the portions that get to extreme temperatures during reentry. A shuttle today would ideally not use liquid fuel. That stuff is a nightmare, both in terms of safety and in terms of the required facilities to maintain its temperature. Instead, it would solely use solid rockets (or a single solid rocket) with adjustable nozzles. This part would be disposable.

      A shuttle designed today, since it would not have to carry the weight of main engines during reentry, could safely handle the weight of an ablative heat shield under the thermal tiles to ensure a safe return. Fewer thermal tiles (say a fourth as many, but 4x as large) would be a big win in terms of complexity and propensity for failure. Use a more flexible binder so that they don't fall off so often, or better yet, hold them in place with a replaceable steel lattice with pins that stick into the edges of the tiles to anchor them even more securely than any glue (or run pins into them from the back or... fill in the blank.

      A shuttle designed today might even have a rear ablative shield and a switch wing design, falling back-end-first through the upper layers of atmosphere, using the ablative heat shield to handle the heat, then at some known altitude, would use the partially deployed wings to reverse its direction and use a chute to slow its descent. Once its descent slowed to a reasonable level, the chute would be detached (with the ablative shield in tow), and the shuttle would continue to fall nose down, at which point the switch wings would be deployed fully and the shuttle would glide in for a landing. You could even put in some small, in-air-safe engines under the heat shield, with a few minutes of fuel to make landing more manageable.

      Anyway, I could rant for hours about all the things NASA (and the military) did wrong in designing and maintaining the shuttle program, but I won't because I'm really glad to see that the current head of NASA doesn't share the rose colored glasses of previous administrators and sees the shuttle for what it is---a good first prototype, but a bad final design. I'm hopeful that eventually we will see something like the shuttle in concept, but radically improved in implementation, even if we do end up stuck with plain old rockets for a while in the interim.

      Part of the reason a shuttle designed today would look very different is because of what we learned from the shuttle. Of course, partially due to limited budgets, we're moving away from the shuttle concept (google CEV if you're unfamiliar).

      That said, I think there's some parts where you're flat out wrong. Rather than deal with the variety of architectures that are possible for a shuttle, I'm going to address them in the context of the shuttle we now have and why it is the way it is.

      The orbiter is not made from steel, it's made from aluminum and titanium. Of course, CF was just budding at the time it was built and was not a feasible technology. It's only now becoming mainstream in planes, but you can expect to see significant amounts of it on future spacecraft, I will grant you that. It will not, however, offer any magical advantages. Merely a little weight-savings.

      The shuttle main engines are liquid fueled because they are significantly more efficient than solid fueled boosters (ISP of about 420 compared to 250 for the SRB's). The solid rocket boosters are desirable because of their extremely high thrust for getting off the ground, but most of the delta V comes from the cryogenic liquid fuels. The wisdom of this choice is reflected in the fact that almost every commercial launcher uses liquid fuel for its core and upper stages, and I think most use LOX (but with kerosene instead of H2). Solid fuels are not without their faults. In addition to low efficiency, their throttling ability is fixed, they can't do a live abort (stop launch once ignition begins), and the fuel can be damaged by excess handling, meaning it needs replacing or the booster may fail.

      The engines are mounted on the orbiter instead of the external tank (as per the Russian Buran shuttle) because NASA was counting on reusing them. At $50 million dollars each x 3 engines (~2005 dollars), reusing them saves $150 million per flight (The Russian engines were cheaper, slightly less efficient).

      There's a lot of room for criticism of the heat shield, but for a winged re-entry vehicle, there wasn't much flexibility for achieving a light weight shield over such a large area. I believe quite a few alternative mounting methods were considered but found infeasible or higher risk, including mounting pins. The size of the tiles was largely affected by the need to flex in flight.

      The Russian space shuttle was scrapped due to lack of money. Given the state of the Soviet Union at the time of its completion and the direction of their space program, it wasn't even worth making do with it after all the money they spent developing it. I don't understand your proposal for a rearward entry or desire for the addition of engines. A rearward entry would not address any of the lessons learned from the shuttle and would only complicate aerodynamics and heat issues. The swing wing would increase mechanical complexity and be difficult to implement for a blunt body re-entry design. No landing attempt has ever come up short, and the size of engines required to enable a fly around would be a significant weight penalty.

      I maintain the view that others have offered. While the shuttle was overly ambitious, represented a needlessly challenging architecture, and did not fit the needs of the space program well as it developed (the shuttle was never meant to be our only manned vehicle), it is an astounding marvel of technology and a fine piece of engineering.

      We may someday see another vehicle like the shuttle, but probably smaller...designed for crew shuttling and maybe as a work platform only. Not for cargo. It will definitely not use the side stack configuration that places the re-entry vehicle at risk from launch damage. That's probably the biggest lesson of the shuttle program.

      All good points. To address a few of those points, I proposed the idea of a switch wing because it makes launch more efficient, turning it into something that approximates a capsule in terms of air flow around it, which would make it easier to have it on top of the stack. It would also mean that you could avoid the heat shielding on the wings almost entirely , as they would not be deployed until a parachute slowed their descent to something more reasonable.

      Fair enough about the liquid fuels versus solid fuels and throttle control, but the hydrogen has been a real nightmare. Maybe dropping liquid fuel is going too far, but at least use a different liquid fuel.... :-)

      The reuse of the engines might save money, but given the amount of service they require per flight, it seems like a cheaper design could have been reached which was less efficient but didn't require constant servicing. Either that or a cheaper, non-reusable design that could be replaced for less than the cost of ripping the engines out, tearing them down, and rebuilding them. Either way, the shuttle costs dramatically more to launch than non-reusable launch vehicles even though the non-reusable vehicles have to be built from scratch every time. It's hard to justify that, and every part that requires a tear down between flights is contributing to that cause, even if that part contributes less than it would if it were replaced outright.

      As for the lack of in-air engines, the reason I suggested that is not because any shuttle landing has failed, but rather because maintaining three runways in the U.S. plus external sites around the world plus having to piggyback the shuttle on a 747 costs a lot of money. A LOT of money. Every time they have to divert to another landing site because the shuttle is so hard to land, that's costing money. If the shuttle had powered flight and switch wings that could maintain altitude at lower speeds, they could bring the shuttle down to a significantly slower speed before the landing, which would reduce the need for such drastic measures.

      Also, if the shuttle had powered flight and an alligator ran across the runway (KSC), you could take off again and come around for another pass. Right now, they land on a wing and a prayer, with Jeeps running up and down the runway continuously for several ours prior to landing to keep the 'gators away....

Yes it is tough to handle, which is why most smaller or lower performance rockets use kerosene, but they incur somewhere around a 25% mass penalty in extra fuel. That has to be accounted for in the engineering.

      I honestly don't know how much service the Space Shuttle Main Engines require between flights, but it's much less than the SRB's, which are the part that takes a disappointing amount of service. On this point, I will note that NASA originally wanted to use the SSME's on the Ares V, but they would not be recoverable on this vehicle, so they went with the Delta IV's engine. I think that suggests the value of recycling engines. SpaceX is also planning on engine reuse for their Falcon series of launchers.

While dividing all of the program costs from inception to now (including R&D and infrastructure) yields a cost per launch of over $1 billion, the fixed costs of launch have been cited at around only $60 million.

Also, I hear a bunch of people complaining about tiles for their cost and fragility, and the usual answer is "ablatives". For those who don't know, applying an effective ablative coating is also very pricey, and the coating is prone to damage as well. Lastly, this statement seems to assume that the loss of a tile is problematic for the shuttle. Shuttle tile losses are not unusual.

    I'm sure the astronauts would be oh so relieved to know that you can't see any reason why damage to their spacecraft won't endanger their lives. I'm sure you will put your livelihood on the line as proof of your earnestness. The engineers who bear actual responsibility for human lives in their decisions, on the other hand, aren't so sure there's no problem.

    You're not wrong that CYA is endemic in government work. You could have added, just as much, in private enterprise. But this has nothing to do with CYA.

    workers have started sanding down the damaged area of the tank itself.

    So sanding down the dings on a high pressure tank is a good idea?

    My wife, an engineer who worked at the Cape for 17 years, immediately cried "bullshit". She says that we get hailstorms like that every year or so, and it's happened enough times before. A friend who still works at KSC, as a tech, verifies this.

    The dithering is because KSC is now staffed overwhelmingly by mostly Republican and fundamentalist types who don't, in fact, know engineering, and *certainly* don't believe in the buck stopping at their desk.

    Then, of course, the GOP has *never* liked the space program, since it became associated with JFK (never mind that Ike started it), and are always looking to cut it, and shift money to the military programs, where their buddies can get big bucks from our tax dollars.

    Don't believe that? Then why are we still flying Shuttles whose *intended* lifespan was 20 years, and we have *nothing* new even in test?

      Not to the same order of magnitude, however. There are more than dings in the foam, there are actual cracks in the foam. Which is a much bigger problem in high-speed high-temperature flow.

      Do what now? GW Bush asked for a bigger budget next year than NASA proposed, guess who shot it down? (Confirmation: here:

      WASHINGTON - The White House's $17.3 billion request for NASA in 2008 demonstrates U.S. President George W. Bush's commitment to replacing the space shuttle by 2014, but might not be enough to offset the impact of a lower-than-expected budget for this year, agency officials said.
      "This increase demonstrates the President's commitment to NASA and to maintaining our nation's leadership in space and aeronautics research," NASA chief Michael Griffin said in a Monday briefing.
      The request, which would give the space agency a raise of roughly $1 billion over this year's likely budget, keeps science and aeronautics spending relatively flat, but does include funds to begin purchasing a new series of data-relay spacecraft.
      The annual budget request tracks very closely with the spending plan the White House sent to Congress this time last year, which sought 3 percent increases for NASA in both 2007 and 2008. However, NASA is unlikely to get a raise this year due to a plan by the Democratic-led Congress to fund most U.S. domestic federal agencies at their 2006 levels.

      Who was it that came up with Star Wars? Reagan.

      Plenty more examples, the GOP likes space access.

      The new test article is the Ares, which is due to complete its first test flight in April 2009. The second launch will commence six months later. The launchpad at KSC (39B) is being handed over to the Ares team at the end of this month for modifications.

      And the shuttles were never rated for a useful lifetime in years - they are rated in number of flights. Namely, 100.
