I searched ATS and found nothing about a declassified joint NASA/U.S. Navy effort to send an unmanned recon probe to Alpha Centauri- the next star!


Longshot would be assembled at the International Space Station, and be propelled on a 100-year flight to the nearest star by a pulsed fusion engine of the type proposed in the Daedalus design. The 6.4-ton spacecraft would carry a 300-kilowatt fusion reactor to power instruments and engine startup, and use a 250-kW laser to transmit data to Earth.


Kind of makes you wonder if all the 'troubles' the station experiences are just for 'cover'.

I found this while reviewing interstellar propulsion proposals.

Anybody ever 'see' the station as it passes over with an amateur telescope?

From wikipedia and wikipedia, it sounds like it has been given up on.

It was done in the late 80s and early 90s. The Wiki articles are weird, saying Alpha (also ISS sometimes) was a precurser to SSF (never made). At any rate, it seems like this project has passed us by.

The method of transport was similar to Daedalus, which, if any of you don't know about, was to basically chuck atomic bombs out the back of the rocket.

The Navy has had its hand in space for a long time- remember Project Clementine and Project Orion? It has had a big advantage in deep space operations thanks to the nuclear submarine program (heavy structure architecture and radiation shielding, powerplant, life support, computation, communication, intelligence gathering, deep black operations experience and covert launch capability) and its contractors (General Dynamics is a major player in both submersibles and spacecraft). The Navy was a prime player in the Moon Base projects of the 1950's, 60's and 70's (Project Lunex) and provided both logistical support and Astronauts to Apollo. The Air Force has more experience with lightweight structures (aircraft) and short-term operations (sorties)- which the Navy also has in the carriers.

So the Navy is a major space player. Maybe that's why Roddenberry called it Starfleet Command. And, it has Marines. May we never need them in space.

As to why they are interested in seeing it. This is only my opinion; but the military never does anything without strategic interest. Defensive, offensive, recon, opening of trade or colonization- military interest is military.

Seems. A fascinating word.

I have a feeling we are much farther along in space than is public knowledge. Which is a good thing. Especially if we really have some sort of 'company' in the neighborhood.

Also fascinating: the Russians would have to be 'in' on this if it went forward secretly using the ISS. Could this have something to do with the 'Alien threat' speeches Reagan gave with Gorbachev?

Bottom line: the Gov't want(ed) to open a keyhole on our neighboring star. The question is why the official interest? I don't think naive simple curiousity is sufficient reason to punch through a study like this hundreds of years before its time. We don't know that there aren't small, Earth-like planets there (publicly) yet. Planets or no, there may be- something- out there. Maybe a signal, or a back-calculated trajectory, something along the lines Ron Bracewell at Stanford was thinking of.

Keep digging on this.

Found some more info. Our nearest neighbor is a multiple star system. There have been several studies that indicate it has stable orbits for earth-like planets despite its multiple suns. Centauri A is a G2V star, slightly larger and quite similar to the Sun; and Centauri B is a K2V smaller than the Sun. Proxima Centauri is an M5 (long-lived) red dwarf. There is also a possible substellar companion (Dyson sphere?) associated with Proxima.

The final Project Longshot report is referenced here.

Note the specialized search tools I used that may be of use to you:

Google Scholar and Pro-Physik.

There is a cool site on Centauri here.

While it seems to be a stillborn theoretical study, NASA usually uses tech that is about ten years post-military. Not too much news is coming out of the new Propulsion Research Laboratory at Marshall Space Flight Center (usually NASA centers are quite vocal about breakthroughs)- so I remain curious.

Optical signals (if there is a probe) from a laser downlink could be viewed with an OSETI set-up (if one knew the frequency, modulation, and possible burst-modes).

Finally, I am hearing some things about multiple star systems like Centauri being used as 'gravitational assist engines' to accelerate spacecraft to enormous velocities, using multiple flyby trajectories. In fact, Centauri has the capability to accelerate entire planets to system-escape velocities. Our neighboring system is a virtual 'warp drive engine'. Conveniently arranged at our doorstep.

And thus deserving of some keyholing.
