NASA's Plans for Shuttles Call for Fall '04 Launching Published: October 4, 2003 ASHINGTON, Oct. 3 — Setting a new timetable for resuming human spaceflight, NASA officials announced on Friday that they would try to launch the next shuttle mission to the International Space Station next September or October. As recently as last month, the agency hoped to fly again by next spring. But on Friday, William Readdy, associate administrator for spaceflight for the National Aeronautics and Space Administration, said the new target date was more realistic, given the amount of testing and modifications that still needed to be done. Moreover, the officials said, both the first flight and a second mission to the space station in late fall or in winter 2004 will be considered test flights. Their main purpose will be to confirm that all the modifications work properly before getting back to the shuttles' primary mission, completing construction of the station. Although station construction will not be a focus of the first missions, both will carry large cargo modules in the shuttle payload bays to help replenish supplies aboard the orbiting outpost and deliver other needed equipment. "This is going to be a long, uphill climb back to `return to flight,' " Mr. Readdy said in a telephone news conference from the Johnson Space Center in Houston, where senior spaceflight managers had been meeting. "But I'll also guarantee you that we're getting an awful lot smarter about this and we're going to come back stronger and safer as a result." "We're going to be very much driven by milestones and by the content that we have to accomplish here," he said. The shuttle fleet — now down to just three orbiters, the Atlantis, the Discovery and the Endeavour — has been grounded since the Feb. 1 re-entry accident that destroyed the Columbia and killed its crew of seven. The Columbia Accident Investigation Board, an independent panel that issued a report on the disaster in August, said NASA had to comply with 15 recommendations to modify shuttles and mission procedures before flying again. Mr. Readdy said the goal now was to launch the Atlantis on a test flight to the space station during a window that lasts from Sept. 12 to Oct. 10, 2004. If the first flight is successful, the second mission to certify that the shuttle system is back in business could come in November, William Parsons, the shuttle program manager, said. But as fall turns into winter, opportunities to fly also narrow because of new constraints, like the requirement that the launching take place in daylight so liftoffs can be photographed in detail. The September launching window is the last substantial one until after March 2005, agency officials said recently. Flight opportunities in November 2004 and January of 2005 last only a few days, they said. "We have some small opportunities in November and maybe January," Mr. Parsons said optimistically. Mr. Readdy said the shuttle test flights would demonstrate methods to repair damaged heat-protection tiles and the crafts' leading wing edges, as well as testing an extension boom for the shuttles' robot arm that can be used to inspect the ship in space with cameras and laser sensors. Other tasks to be completed before flights resume include redesigning the external fuel tank to prevent insulating foam from breaking off. Columbia was damaged when a piece of foam debris from the tank bashed a hole in the leading edge of its left wing shortly after liftoff, allowing the superhot gases of re-entry to penetrate the wing at the end of the mission. Mr. Parsons said that the Atlantis was still scheduled to fly the first return-to-flight mission, but that a final decision would be made after resolving an issue with its nose cap. Engineers recently discovered discrepencies in records concerning the shuttle's last major overhaul in 1997-98 that raised questions about how thoroughly the cap had been inspected. Corrosion was found on the metal framework under the nose cap of another shuttle, a problem that has been inspected or repaired on the orbiters Discovery and Endeavour, officials said. But Mr. Parsons said the issue of the Atlantis's nose had not been resolved yet and he did not know if an extensive inspection that would pull the shuttle from the flight line would be required. This raises the possibility that another shuttle might make the first flight, Mr. Parsons said. "The mission is not orbiter-dependent right now," he said. |

But on Friday, William Readdy, associate administrator for spaceflight for the National Aeronautics and Space Administration, said the new target date was more realistic, given the amount of testing and modifications that still needed to be done. Procrastination time is here again! Delay, Delay, Delay, and Delay. Moreover, the officials said, both the first flight and a second mission to the space station in late fall or in winter 2004 will be considered test flights. Their main purpose will be to confirm that all the modifications work properly before getting back to the shuttles' primary mission, completing construction of the station. Yeah what's the hurry! With 3 flights a year, NASA is going to waist 2 of them on test flights. This is a terrible Joke! By the time NASA finishes its space station with the stupid shuttle. China will have launched two. NASA seems to think that finishing an antique space station in 3 or 4 decades is the same as finishing the station in 1. Some projects after so many delays just aren't worth continuing. Seems worthwhile to look at developing alternative vehicles rather than fixing the shuttle and putting a "Chuck Yeager" in the cockpit to test it, so he'll have the "Right Stuff" Tom |

Better look for the next launch in Spring of 2005....

On or about 6 Oct 2003 14:20:44 -0700, Daniel made the sensational claim that:
Better look for the next launch in Spring of 2005.... Daniel *plonk* Go away. -- This is a siggy | To E-mail, do note | This space is for rent It's properly formatted | who you mean to reply-to | Inquire within if you No person, none, care | and it will reach me | Would like your ad here |

![]() Better look for the next launch in Spring of 2005.... Daniel My feeling too, there are always problems found that must be fixed. Like the latest nose cone inspection. Besides theres a long time of no launch possible if they miss the fall 2004 target date due to new flight constraints. like a just 3 day window in january. Find just a few problems with any orbiter during inspection and theres going to be anoth schedule slip. |

When you consider the scrubs due to weather, I really wonder how many launches they will be able to make during one year. Miss your window and you have to wait months before you're allowed to launch again. Will they want to leave an orbiter on the pad for months ? Or will they bring the orbiter back in the VAB ? For a few months, would they de-stack and leave it all ready on the MLP ? What impact would this have on the processing/preparation of the other orbiters ? Is the VAB big enough to assemble shuttle #2 while shuttle #1 is parked on an MLP, all stacked and ready to go ? The daytime launch criteria may be the shuttle's downfall and may render the shuttle useless if it means it can only fly a couple times a year. Once they have tested the on-orbit inspections and tile repair, is there any chance that they would then allow shuttles to launch in dark since launch film won't be so important anymore ? |

Is the VAB big enough to assemble shuttle #2 while shuttle #1 is parked on an MLP, all stacked and ready to go ? Yes. The VAB is now capable of having 3 fully assembled shuttle stacks. And we just happen to have three MLPs, so it works out. The daytime launch criteria may be the shuttle's downfall and may render the shuttle useless if it means it can only fly a couple times a year. Once they have tested the on-orbit inspections and tile repair, is there any chance that they would then allow shuttles to launch in dark since launch film won't be so important anymore ? |

I wonder if some of the reason is to avoid the "appearance of eagerness" with a March '04 launch. I recall there being some grumblings in Congress when NASA proposed their spring launch date and a delay, even if NASA were 100% ready, might quell speculative musings. How much of the delay is due to Atlantis? None, if the mission is not orbiter dependent. Therefore, if the nose corrosion issues have been addressed with Discovery and Endeavour, what is the real reason for the delay? |
