Some thoughts on a possible stealthy re-entry Atmospheric: 1) fire your rockets/retros etc to match the speed of the highest part of the atmosphere where you might start getting 'hot' while over the day side of the planet, outside the atmosphere and still hidden from the naked eye by the 'blue sky' effect (any thermal signature should be difficult to distinguish from some minor atmospheric fluctuation, or perhaps a dark colored bird passing overhead)
2) Target your re-entry over a thickly clouded area to maximize thermal/atmospheric interference. 3) use glide-surfaces or active atmospheric controls to slow descent(like a stealth airplane, just starting out a little higher) Trace or less atmosphere: approach in a controlled tumble and only fire retro rockets at the last second to minimize opportunities for observation. (should look like a big rock until you fire the rockets) On Mon, Nov 17, 2008 at 1:44 PM, David Scheidt <[EMAIL PROTECTED]> wrote: > On Mon, Nov 17, 2008 at 2:33 PM, Evyn MacDude <[EMAIL PROTECTED]> wrote: >> On Mon, Nov 17, 2008 at 11:02 AM, Roger Burton West <[EMAIL PROTECTED]>wrote: >> >>> On Mon, Nov 17, 2008 at 07:14:34PM +0100, Onno Meyer wrote: >>> >Next Week: Probably a stealthy TL11 shuttle. >>> >>> Is there any practicable way of making a reentry vehicle stealthy in the >>> real world? >>> >> I'd have thought that the ionisation phase would be pretty >>> obvious no matter what you make the vehicle itself out of... >> >> >> Enter the atmosphere slowly.... > > Requires firing a rocket motor.
