If this report is true, it looks like NASA is not going to hit its milestone of the first test flight of the Potemkin RocketAres 1-X vehicle planned for a year from now:
Ares I-X now has little chance of making its April, 2009 launch date target, initially due to the delay of STS-125’s flight to October.
The first Ares related test flight requires the freeing of High Bay 3 inside the Vehicle Assembly Building (VAB) and Pad 39B – which will first host STS-125’s Launch On Need (LON) rescue shuttle (Endeavour/LON-400) – being vacated for modifications ahead of Ares I-X.
However, a new problem has now come to light with the MLP (Mobile Launch Platform) that will be handed over from Shuttle to Constellation for the test flight. This problem relates to the stability of Ares I-X during rollout to the Pad.
The modifications to the MLP initially called for Ares I-X to be placed on one set of the existing Shuttle’s Solid Rocket Booster (SRB) hold down posts, with a tower to be erected on the other set of hold down posts – with support for the vehicle between the tower and the interstage level.
When NASA changed contractors for the MLP work associated with Ares I-X, the design changed, omitting the adjacent tower, instead relying on three steel cables – 120 degrees apart – to help hold the vehicle steady during rollout.
Given the projected weight of the vehicle at rollout – with a heavy dummy upper stage – additional stability is now being called for, leading to a redesign of the MLP support structure.
In combination with the projected delay to handing over Shuttle resources post STS-125, internal scheduling is showing 60 to 90 days worth of delay to Ares I-X’s projected launch date.
Gee, it’s always something. Guess that’s what happens when you come up with a new vehicle concept with a ridiculously high aspect ratio, that makes a whip antenna look positively zaftig. Has anyone ever had to use guy wires on a rocket before, or is this another proud first for our nation’s space agency?
Anyway, as it goes on to point out, this probably will waterfall down through the whole schedule, further increasing the dreaded “gap.” Not that it will matter that much, once the budget gets whacked in the next administration, regardless of who is president. But then, maybe if they’d come up with an implementation that actually appeared to have some relevance to peoples’ lives, instead of redoing people’s grandfather’s space program, they’d get more public support, instead of ever less.
It’s hard to see how this ends well, at least for fans of Apollo on Steroids. But it’s mostly irrelevant to those of us who want to see large-scale human expansion into space. That will have to await the private sector.
