NASA Instituting Crowd Control on Shuttle
From the story at:
http://abcnews.go.com/Technology/print?id=606743 NASA Instituting Crowd Control on Shuttle NASA Instituting Strict Crowd Control to Better Protect Public During Shuttle Launches, Landings By MARCIA DUNN The Associated Press Mar. 23, 2005 - NASA said Tuesday it will institute strict crowd control for space shuttle launches and landings, and rely more on a seldom-used touchdown site in New Mexico, to better protect the public once flights resume in a few months. Columbia's breakup during re-entry forced a re-evaluation of the space agency's public safety policy. More than 85,000 pounds of debris rained down on Texas and Louisiana as Columbia headed toward its Cape Canaveral landing strip in February 2003. No one was injured by the falling pieces. "Philosophically, what we're trying to do ... is to ensure that whatever it is we're doing, does not add significantly to the overall risk that the public already accepts," said Bryan O'Connor, chief of safety and mission assurance and a former shuttle commander. No one on the ground has ever been hurt by a U.S. spaceflight. O'Connor said that when Discovery lifts off on the first post-Columbia flight, as early as mid-May, it will be the first shuttle mission in which public safety is factored into deciding where to bring the spacecraft home. Kennedy Space Center will remain the primary landing site, but only if the shuttle has no problems that might endanger people on the ground, such as a problem with the flight-control system or damage to the ship's thermal skin. In that case, the shuttle would be directed to White Sands, N.M., a remote, dusty missile range that has seen a shuttle landing only once, back in 1982. "This is a risk trade," O'Connor said. "You'd have to be sure that all other things being equal, that you have good weather there, that there's not some other matter like, for example, crew safety or you're about to run out of consumables because you've already been on orbit for a couple of days, waiting to come down. All those things will be factored in, but for the first time now, public safety will be one of those factors." As for shuttle launches, the number of people allowed to gather at the three- to four-mile safety perimeter will be greatly reduced, as will the size of the crowd at the Kennedy runway for landing. NASA will also bar people from being beneath the final glide path. Unlike an airplane, a space shuttle glides to a landing and cannot change its flight path once the braking rockets are fired one hour before touchdown. In unveiling the 288-page plan, NASA said it is looking increasingly difficult to stick to the May 15 launch date for Discovery, which is still in the hangar undergoing last-minute repairs and inspections. Shuttle program manager Bill Parsons said he will re-evaluate the launch date in mid-April. The delays in getting the shuttle ready to be moved to the launch pad a step now targeted for early April are for technical reasons, such as wiring inspections and landing-gear checks. As far as meeting the Columbia Accident Investigation Board's 15 recommendations for resuming shuttle flights, seven have been fully met and another is on the verge of being fulfilled. Of the remaining seven, virtually all of the necessary paperwork has been submitted to the task force that is overseeing NASA's return-to-flight effort. The task force will meet March 31 to consider NASA's progress. NASA estimates the return-to-flight expenses will exceed $1.6 billion. On the Net: http://www.nasa.gov/returntoflight/main/index.html |

I guess Edwards doesn't provide enough public safety.
Anyone happen to have a chart for a shuttle re-entry profile from ISS orbit to White Sands? -A.L. |

oups.com: I guess Edwards doesn't provide enough public safety. Anyone happen to have a chart for a shuttle re-entry profile from ISS orbit to White Sands? The groundtrack for a particular entry depends strongly on the crossrange; it can vary up to 800 nmi either way. The range of groundtracks possible for each landing site was depicted in one of the shuttle program's return-to-flight briefings, and I vaguely recall that it was available on the web, but I haven't found it yet. -- JRF Reply-to address spam-proofed - to reply by E-mail, check "Organization" (I am not assimilated) and think one step ahead of IBM. |

Some of the problems resulted from landing there being a last-minute decision, with all the convoy equipment having to be loaded onto a train at Dryden, but a lot of it was caused by the White Non-Sands. That stuff is very fine, not at all like sand, and hygroscopic, so the Orbiter went from being filled with dust to being filled with sticky mud. When the mud dried out, it was very hard and very difficult to remove, particularly from inside small holes, behind panels, etc. "Dusty" is an understatement, by the way.

If I remember right, NASA didn't land at KSC until well after the White Sands landing. Jeff -- Remove icky phrase from email address to get a valid address. |

Early 1984 to be exact, STS 41-B (though at least one flight earlier had been scheduled for KSC but diverted). I seem to recall at least one of the early post-Challenger missions being diverted from Edwards to KSC, which IMHO illustrates just how much of a "last resort" White Sands has been seen as. -A.L. |

Of course, it's not a factor in this scenario. Remember, we are talking about an orbiter that is already *known* to be compromised. Even assuming it lands intact, that bird will never fly again. So cleaning up the "incredible mess" would become the Smithsonian's problem, not NASA's. -- JRF Reply-to address spam-proofed - to reply by E-mail, check "Organization" (I am not assimilated) and think one step ahead of IBM. |
