NASA's Electrodynamic Tether Propulsion Demonstration Mission

NASA MSFC RFI: Electrodynamic Tether Propulsion Demonstration Mission

"NASA MSFC is seeking a partner capable of providing a spacecraft bus as a part of a technology development proposal team. Responses to this RFI will provide information necessary for the selection of spacecraft providing partners for the proposal team in late Summer/early Fall 2010. This RFI seeks input from vendors with experience and facilities for designing, fabricating, and integrating Low Earth Orbiting (LEO) satellites. Vendors must be able to provide low risk, highly reliable design solutions and have a history of successfully delivering spacecraft bus systems to support Flight projects."

Excellent!

After years of being ignored, it's great to see that it looks like there's a chance that some tether concepts for advanced propulsion might actually flown!

This is great news. Advanced propulsion systems, once they progress beyond the proof of concept stage, need to be tested in orbit. Tethers and other possible methods of electrodynamic propulsion should be investigated more actively.

With all due respect to those involved, sure, it's an interesting concept but impractical to the point of being a waste of funding at a time when there are far more critical needs at NASA.

The satcom, WX and elecro-optical satellite systems in orbit are a trillion dollar system with hundreds of billions to potentially in excess of a trillion dollars per year of generated benefit. Tether power is one way to greatly extend system lifetime. Hard to see many more critical or important benefits and needs at NASA.
