The mission is aimed at studying the climate, geology, origin and evolution of the red planet, according to the Navratna defence PSU headquartered here.
"The satellite structure is an assembly of composite and metallic honeycomb sandwich panels with a central composite cylinder," HAL Chairman R K Tyagi said.
The assembly work was carried out at HAL's aerospace division here. ISRO will build the other satellite subsystems and scientific payload onto this structure. The completed satellite will ultimately embark on a voyage to orbit planet Mars, HAL said.
ISRO has already announced that it plans to undertake the Mars mission in November next year.
