1) The body of Mariner 6 was made with Magnesium Frame
2) Four solar panels produced 449 watt power for spacecraft
3) Communication were made with high gain parabolic antenna.
4) And through Omnidirectional low gain Antenna using S-band travelling tube amplifiers.
5) It was tracked by Canopus Tracker and a Star Canopus
6) Spacecraft position were adjusted with newton rocket motor with hydrazine fuel
7) Photovoltaic cells produced 800 watt of power near Earth and 449 watt after reaching Mars
8) It had a mounted 1200 watt Silver-Zinc Battery for power backup.
9) An Analog tape recorder of 195 million bits installed to collect data.
10) It had a capacity to perform 53 direct commands, 5 control commands and 4 quantitative commands.


     It flew over northern and southern region of Mars, and took photograph of northern giant volcanoes and a grand canyon. Later it found creators and canals. Totally it took 201 photographs and transmitted back to Earth. It gave much details ever than all earlier missions. It also studied the atmosphere of Mars.
