Well it does state in your graphic there that the closest approach wont be until October 1 , so thats probably the best time for it.
Im not sure what the conspiracy is ?

When Comet ISON was discovered last year, it was so bright that some thought it would outshine the moon. But it hasn't brightened as much as predicted. Its early outbursts, originally thought to herald a huge comet, were instead carbon dioxide frost evaporating from a metre-thick coating it collected in the solar system's frigid outer reaches.
plans are afoot for the Curiosity rover and the Mars Reconnaissance Orbiter to attempt imaging the comet when it makes its closest approach to the Red Planet on October 1st at 0.0724 Astronomical Units (A.U.) or 10,830,000 kilometres distant. If MSL is successful, it would be the first time that a comet has been observed from the surface of another world.

When did they make the buggy capable of coming back to Earth?

Mars Reconnaissance Orbiter communicates with the Deep Space Network antennas on Earth using two different kinds of radio waves:
X-band: the current standard in communications, which, when amplified, allows the orbiter to send data back to Earth more than 10 times faster than previous missions.
Ka-band: a previously untested radio frequency four times higher than X-band, which allows scientists to bring data back even faster.
From the viewpoint of a Deep Space Network antenna on Earth, the orbiter spends about one-third of its time behind Mars during each orbit. During these times, the orbiter is "occulted from the Earth." During occultations, Mars Reconnaissance Orbiter cannot usefully send or receive radio signals.
NASA Deep Space Network (DSN)
The NASA Deep Space Network - or DSN - is an international network of antennas that support interplanetary spacecraft missions and radio and radar astronomy observations for the exploration of the solar system and the universe.
So, out of 16 hours of daily Deep Space Network tracking, Mars Reconnaissance Orbiter sends data to Earth for 10 to 11 hours, and does that for about 700 days. The data rate is about 0.5 to 4 megabits per second. With these figures in mind, the estimated volume of data returned by Mars Reconnaissance Orbit was predicted to be about 34 terabits. In fact, the spacecraft has already returned more than 50 terabits of data -- more data than all previous planetary missions combined.

Is Curiosity already on earth? no..think it wait for ISON..Get the sampel Of It and bring back to earth for Preparation..

Here's 1 video of many predicting this is the event.
Second: Inbound Ison will pass above the Earth's orbit at a distance of 4 times greater than the Moon's orbit.

i think there is a Conspiracy of this Connection..

Well technically the Apollo program was a "return sample" mission...
Perhaps one of the most significant advances in sample return missions occurred in 1970 when the robotic Soviet mission known as Luna 16, successfully returned 101 grams (3.6 oz) of lunar soil.
Luna 20 returned 55 grams (1.9 oz) in 1974 and Luna 24 returned 170 grams (6.0 oz) in 1976. Although they recovered far less than the Apollo missions, they did this fully automatically.
