The really cool thing about viewing Earth from Mars is that Earth is inward of the solar system, rather than outward. It would exhibit phases like Venus does when viewed from Earth, as it orbits around the sun. So you would have New Earth phase, Waxing Earth Crescent, Waxing Earth Half, Waxing Earth Gibbous, Full Earth (largely obscured by the sun, only visible as it enters and leaves this phase, and then only moments after the sun has set on Mars), Waning Earth Gibbous, Waning Earth Half, Waning Earth Crescent.
Even cooler than Venus...with a powerful enough telescope, you could probably see the Moon's phases as well...what a sight that would be: Waxing Earth Crescent with a Waning Moon Half.
That would be an epic view ... one married guy from Qatar got selected to go on a one way journey to Mars, so maybe he'll get to see "Waning Earth Gibbous, Waning Earth Half, Waning Earth Crescent" etc
That would be one crazy trip. Maybe someone will bring along a 28" PlaneWave CDK and an ASA DDM160 mount for "Earth Observing".
I don't think it's going to happen, though. The sheer cost of such a trip is so astronomical, not even the world's most popular reality TV show could maintain the funding for it. It would become the single most expensive project the world has ever seen, and I don't think anyone can truly survive on Mars. Not permanently. Honestly, I think when the time comes, if they really do try, it'll end up being a disaster. There are SO many things that could go wrong, not the least of which is food and water supply problems, but also technical issues and personnel issues. Even assuming they try to maintain a supply chain of food and water deliveries, that just means the cost never ends, and they would always need funding.
The key problem with the Mars One mission is the masses of people who would be required to fund it by continually watching the reality show will eventually get bored. Even if the show maintained a core viewership that would never leave, they would never represent the tens of millions of sustained viewers necessary to extract the kind of advertising revenue necessary to sustain the mission.
There is also the inevitable TRUE realization of what these people are signing up for means...a ONE WAY trip to Mars. People think that's amazing right now...but there is no rescue plan, there is no return ship, there is no return period. It is a PERMANENT LIFE CHANGE, on a scale no one on Earth has experienced before. Psychologists can't gauge the effect of that on people, even if they try. That will have to sink in on multiple levels before people finally get it, and when they do, I'd say as much as half the people who sign up for a one way trip to Mars end up snapping once they are stuck there for a LONG year of MASSIVE hardship and the ever-present long-term threat of danger, going ape-S___ crazy, when they realize they are literally marooned on another planet with no hope of return...or at least, no hope unless the Mars One mission ends up building a rescue vessel (which would take years, so all these crazy people just keep on the crazy that whole time...you know what crazy people do to space missions...we've all seen the consequences of THAT via hollywood for enough years).
Mars One...exciting idea...bad idea. Anyway...
