Sounds like a Mars Orbit mission. Possible to create such a mission plan and the needed hardware until start in 2018? I have my questions, but hey, party time!

I think they should aim for a lunar orbit mission first. (assuming its manned). Mars is far too ambitious in the time frame.
However they may have something new. The press conference will tell.

Edit: On reflection, perhaps its a non stop with Venus and Mars flyby, maybe probe dropoffs at Mars and Venus. That would be much less demanding propulsively, and could be done with ISS technology.

Figure out the initial mass in LEO required for a human mission to Mars.

Figure out the initial mass in LEO required for a human mission to Mars.
Huge dependence on number of astronauts, what kind of orbit you enter, what kind of ECLSS, what kind of space you think they'll need, and mission mode (long-stay, short-stay, fast-transit, etc).

For minimum, I'd say look at what it'd take to push Salyut 7 (just the main module, plus an attached Soyuz) through the delta-v of barely entering Mars orbit (perhaps with slight aerobraking), then leaving Mars orbit ~500-600 days later for trans-Earth insertion. 1kg/astronaut (very calorie-dense food, efficient ECLSS) for 1100 days for 2 astronauts. And lets say the whole stack starts at EML2.

In that case, there's about 1km/s until trans-Mars insertion, 1km/s .9km/s for Mars capture, 1km/s .9km/s for Mars departure (and reentry at Earth) for a total of 2.8km/s delta-v. Assuming something equivalent to Block-D (stretched, having a dry mass of 4000kg), maybe slightly better (EDIT:hypergolic), we have an exhaust velocity of 3.4km/s3.2km/s.

Soyuz is ~7000kg.
Consumables maybe 2000-4000kg (we need some margin here, 1kg/day is pretty optimistic...).
Salyut 7 is 20000kg.
Dry stretchedBlock D used for all large maneuvers: 4000kg
Total: 35000kg.
35*e^(2.8/3.2)=~85.

So, about 85 tons for two astronauts at EML2. Obviously much more for the actual IMLEO, but that's dependent on propulsive technology used to get there. 85 tons isn't bad.

EDIT: I think full hypergolic would be better than using kerolox, simply because we know how to store hypergolic fuels for decades. To counter-act, we can assume .9km/s each way into/out of mars capture, to get basically the same total mass at EML2. I had forgotten at first that Blok D was kerolox.

They are sufficiently vague about that aren't they?

Maybe it's something else...

I'd actually welcome that, since it'd be evidence they might be able to actually pull it off.

IF it is a manned mission and IF it is 2018 the only thing I can think of is a ONE man FLYBY mission. Mars (plus maybe Venus). I do not think there is any chance of going into orbit this time around.
Shoukd be doable w F9H (2 of them?)

Get Red Bull as sponsor and design a mission logo that can be seen on TV when watching racing cars.

Is there existing tech that would allow them to land someone on Mars and get them back to the ship?  Would the Dragon capsule be capable of land touchdowns by then?  Or as others have mentioned would this be a Mars flyby mission?  Maybe a Phobos landing?

A crewed Mars mission 5 years from now sounds to me kind of "adventurous", I don't know if they'd be able to pull something like that off in that timeframe, after all it wouldn't be till at least 2030 till NASA gets there, if they get funded.  But I wish Inspiration Mars luck!
I'll even excitedly look forward to "flags and footprints" and suborbital missions. Just fly...somewhere.

Landing and ascent is out of the picture for 2018, manned or unmanned.

Why?

The technology isn't developed (well, i suppose you could do an unmanned landing and ascent, but it'd mean using the enormously expensive Skycrane technology). Surprisingly, we do actually have the technology already for a manned orbital mission. So do the Russians.

May I ask one of our gurus here to make some calculations how a voyage of 501 days looks like with a start in 2018? Fly-by? Mars orbit? Anything else?

Second, if paragon is involved and they really like to start in 2018 they need already be finished with a long duration ECLSS and have tested it for the last 500 days or so.

Missing link will be a return capsule, a habitat, a rocket and the complete mission package, like planing, communication, etc.

It's actually quite simple, when you think of it:

* Bigelow hab module;
* Hydrolox kick stage (maybe a dual-engine Centaur as per Golden Spike's idea);
* SEP sustainer;
* Remote assembly at EML-2;
* CST-100 or Dragon CRV, launched to EML-2 by Falcon Heavy.

This is completely sufficient for a free-return Mars flyby; heck you could use a different trajectory and include a Venus flyby too! It's still amazingly dangerous but, and let's be clear here, it's their lives and money to risk.
