Comment on Power Generation Onboard Spacecrafts (IV) by dj

I found something on this matter… the United States issued a policy statement in 1988 related to minimization of the amount of orbital debris produced by space mission:

“All space sectors will seek to minimize the creation of space debris. Design and operations of space tests, experiments and systems will strive to minimize or reduce accumulation of space debris consistent with mission requirements and cost-effectiveness. The United States government will encourage other space faring nations to adopt policies and practices aimed at debris minimization.”

(see Alan C. Tribble – The space environment – Implications for spacecraft design, Princeton University Press, 2003, p.212)

Hi Tom,

I asked myself the same question. I guess space debris management will become a booming business in the next 20 years or so.

Hopefully, international laws now in effect prevent the participants in the space program from (literally) throwing their own garbage over the fence.

Thank you for the feedback!

So, the RORSAT cores won’t re-enter the atmosphere for a couple of centuries. Well, that’s certainly reassuring in the short term. What happens to our descendants, then, when they eventually do, given that the people who built and launched the wretched things evidently considered re-entry of reactor cores to be something sufficiently nasty to make sure it didn’t happen within their own lifetimes?

I’ve read about these too, and wondered about air friction on the shaft. Wouldn’t it have to go as fast as the satellite at the top? That could be pretty interesting at sea level.

Truly it is a sad news for India and for me . But we have to face it. I was very optimistic about chandrayaan.Anyway most of its scientific goals have been met.
