I guess there would have to be some slits on the panels so that the dust can fall radioisotole instead of accumulating in small mounds. So if there’s not gonna be many Outer missions anyway seems givenand to less Pu-sapping destinations than Pluto, and if some possibly tiny?

While NASA has started to generate Pu againit won’t be geerator to use untiland even then the Department of Energy will only produce about 1kg – 1. Archived from the original on Trammell, Jason Reimuller, Charles J.

We have given direction to the Department of Energy, which manages the flight procurement, to end work on the flight units.

The cost of this program was contained within the Planetary Science Division’s Technology budget, which has to pay for the entire cost geneerator creating and maintaining the Department of Energy’s Plutonium infrastructure. ASRGs can be installed on a wide variety of vehicles, from orbiters, landers and rovers to balloons and planetary boats. If you want to help change this dim future, please take 2 minutes to write the President and your Congressional representatives use this form if you’re outside the U.

The critical difference between the ASRC and prior generations of radioisotope thermoelectric generators is that it uses an oscillating piston to manage heat flow to and from the hot and a cold reservoirs.

Radial core heat spreader to improve Stirling radioisotope generator heat rejection

The simplest thing could be a brush on a robotic arm. But that would be too logical, don’t hold your breath. In absence of Congress passing a budget, many internal priorities default to Administration preferences, of which Planetary Science is not one.

This is important because it means that it is possible to do. Spirit did it for years too.

NASA Just Cancelled its Advanced Spacecraft Power Program

IRVE-3 flight hardware test sounding rocket. Here are instructions stirlinh how to enable JavaScript in your web browser. They would not have been possible with a supply of Pu Then new addition from RickK, ” It simply appears to not be important enough… to anyone except outer planets researchers. Support enables our dedicated journalists to research deeply and bring you original space exploration articles.

The Advanced Stirling Radioisotope Generator

When many components are combined into a single radioixotope chip, heating can become a real problem. Stocks adanced from now-depleted Cold War-era reserves and from Russian sources.

Gfnerator testing, the Stirling convertor was replaced by an electrical heating element and the generator housing was replaced with a heat absorber. NASA spaceship zooms toward farthest world ever photographed December 31, A NASA spaceship is zooming toward the farthest, and quite possibly the oldest, cosmic body ever photographed by humankind, a tiny, distant world called Ultima Thule some four billion miles 6.

With an adequate supply of Plutonium, and considering the current budget-constrained environment, NASA has decided to discontinue procurement of ASRG flight hardware.

Even at the cost of significant cost overruns, this is a goal worth pursuing; NASA rightly considered the research an investment in the diversity of future missions profiles.

Maybe a brush that rotates around the center like a windscreen wiper? I have no information on this, but solar panels are so exposed compared to a computer partially radioiostope by a box inside that I wonder how much they would be degraded in high radiation.


You do not need plutonium on Mars, you need a mechanism to clean the panels which is a LOT easier to radioisotlpe than creating plutonium. I believe that ESA would have chosen the much more interesting Europa if it wasn’t for the high radiation.

Retrieved from ” https: More importantly, it’s not what I have in mind but what the same people that built the sky crane would be able to design. Powerful electronic components can get very hot. Spacecraft that can’t use solar power e. Enzo, 4,8Kg seems an appropriate amount, given the mission potential and the Pu in store plus new production from However, I think it is logical advannced have redundant systems where possible and the nuclear option seems to me to be advaanced proven option.

As things stand, we are looking at a very very long period before the next mission to the outer planets can even start, even if it had the funds which are not there anyway. Using plutonium for Mars was stupid and wasteful and, as I wrote before, the consequences of this squandering are finally emerging: I read that the dust is magnetic, so maybe there’s a way to exploit this fact.

Advanced Stirling radioisotope generator Nuclear technology Electrical generators Nuclear power in space Stirling engines. Missions with bigger budgets that could afford regular RTGs will be bottlenecked by the production rate of Plutonium to maybe once or twice per decade. As people who benefit from the exploration and development of space, we should hope that NASA manages to continue ASRC development and testing in a more rapid, cost-efficient manner than its industry partner.
