Columbia Accident Investigation Board Issues Preliminary Recommendation Five: On-Board Ascent Imaging
For Immediate Release
CAIB PA 38-03 Date: July 30, 2003 Contact: Lt. Col Woody Woodyard, 703-416-3532 Laura Brown, 703-416-3532 or 281-467-8657 Columbia Accident Investigation Board Issues Preliminary Recommendation Five: On-Board Ascent Imaging ARLINGTON, VA - The Columbia Accident Investigation Board today issued its fifth preliminary finding and recommendation to the National Aeronautics and Space Administration, in advance of its appearance in the final report. Recommendation Five: Provide a capability to obtain and downlink high-resolution images of the External Tank (ET) after ET separation. Modifying one of the two umbilical cameras to meet this requirement is acceptable. Provide a capability to obtain and downlink high-resolution images of the underside of the orbiter leading edge system and forward section of both wings' Thermal Protection System (TPS). Facts: Imaging the Space Shuttle System during launch and ascent provides necessary engineering data including the ability to examine the Space Shuttle System for any unexpected debris or other anomalies during ascent. The Shuttle has two on-board cameras that image the ET after separation, but the images from these cameras are available only post-flight. Very little engineering quality, on-board imaging of the ET was available for STS-107. Findings: There is a requirement to obtain and downlink on-board engineering quality imaging from the vehicle during launch and ascent. Background: The Space Shuttle is still a developmental vehicle, and engineering data from each launch is essential to further understand the vehicle. An ability to provide engineering quality imaging data of the ET after separation is important to determine if any debris from the ET was shed during ascent. Since the total elimination of all sources of debris has not yet been achieved, a much better understanding of all the potential sources of debris is required. Since the total elimination of all sources of debris has not yet been achieved, early detection of debris strikes against the forward underwing TPS of both wings will increase safety margins. The CAIB is aware of the excellent preliminary work already in progress at NASA in this area. -- ---- Jacques :-) Editor: www.spacepatches.info ------------------------------------------------------ |

Recommendation 5.7 WAS:( Columbia Accident Investigation Board Issues Preliminary Recommendation Five: On-Board Ascent Imaging)
Add a couple of cameras to the ET and take some video of the Orbiter's
bottom for downlink. Craig Fink Jacques van Oene wrote: For Immediate Release CAIB PA 38-03 Date: July 30, 2003 Contact: Lt.

Recommendation 5.7 WAS:( Columbia Accident Investigation Board Issues Preliminary Recommendation Five: On-Board Ascent Imaging)
Thinking as I type this, but surely the cameras will have to be both wide
angle and very high res bevcuase the wide anglness(:-)) will make the detail very hard to see. I guess some form of very wide screen mode could be used, but whatever it uses, they are going to have to watch the lenses as the boosters come loose, I fancy.

I'd imagine the lighting conditions at ET sep will require much thought as well, as the angle of the sun and reflected light from Earth will be unique to each flight depending on inclination and what time of day they launch. -- Sent to you by Ken at: replace 'who?' with 'b2' for email |

Recommendation 5.7, etc.
"Brian Gaff" wrote in message ... Could some form of radar be used to look at these surfaces, from the tank? Maybe milimetric scanned repeatedly? I doubt that foam would reflect radar very well, and I think you'd have to make quite a bit of room in the belly somewhere for an MMW radar that would be used only for a little while. A LIDAR System might work better, though, and it wouldn't take up as much space. |
