Yes, a solar array
can make enough power because in the vacuum of space sunlight is raw and very strong compared to what we normally see on earth.
Next,
every ICBM has a radioactive isotope power cell in it that lasts for decades and decades and the stock ICBM radioactive power cell unit has enough juice to power a mild small magnetron powered "no fuel needed" drive for unmanned trips.
(if you don't care about the whole thing getting slowly radioactive, that is) Constant low boost levels still builds up over time, if it is unmanned, to
very high speeds and fairly quickly at that.
So the solar array can do it, and the ICBM isotope power cell technology can do it. Unmanned stuff can substitute time for raw power and get there just the same.
The Russians are looking for
less than 30 days to get people to Mars, using a fission rocket plane technology they spy stole from the American Air Force, which has had its own top secret Space Agency since the 1960s.
Look it up, the
Air Force had its own small top secret space station long long before Skylab was ever financed or launched. Back before NSA's satellites got good enough, we
kept a few people in orbit over the USSR during the height of the cold war. Were they sitting on a bunch of short range interceptor missiles? Who knows ....... but once the rocket boost phase is over the Russian war head package (pre-separation package) is a ballistic turkey shoot using sparrow type radar homing missiles from a similar speed orbit.
Do you think the Russians folded up over Star Wars if it wasn't a real viable credible threat during the Reagan years?We have retired Air Force people leaving documents to be read after they died saying they have personally been to Mars (which gets instantly completely discounted and disbelieved until you remember those Air Force blue colored EV suits that were discovered with those name tags that nobody can identify behind an abandoned locked unmarked door down an abandoned locked unmarked hallway at the Kennedy Space Center).
Our Government and Military
keeps secrets pretty durn well, really they really do. And I guess they should keep them secrets since we signed treaties and all with the Russians about not our not militarizing outer space after the treaty was signed (it doesn't say shite about us already having it sitting up there, you know)
Over 30 years ago there was a hushed up flap over an Air Force X plane making an emergency landing on a strip of New Mexico highway, leaving 3 miles of that highway mildly radioactive from a malfunctioning fission rocket drive.
We know we built and tested a high orbit-capable-from-the-ground fission rocket powered space plane over 30 years ago ....
Over 30 years ago we really did have orbital refueling "Mars visit capable" fission rocket plane technology available to us.
Do you really think the "right stuff guys" didn't go there? Bullshite ....
and now we got dead right stuff guys now saying they did go orbit Mars, and the radiation from the fission space drives eventually killed them with long term cancer.
