PRL has proposed and developing the following instruments for second Indian Mars Orbiter Mission (MOM-2). These instruments have been selected for MOM-2 and are at various stages of the development.

To understand origin, abundance, distribution and flux at high altitudes on Mars, a MODEX is proposed. There are no measurements of Interplanetary Dust Particles (IDPs) at Mars. The instrument can detect particles of size from few hundreds nm to few µm, travelling at hypervelocity (> 1 km/s). The outcomes can help explain the dust flux at Mars, whether there is any ring (as hypothesized) around Mars and also confirm whether the dust is interplanetary or coming from the Phobos/Deimos. The study of dust can help explain the RO experiment results.

To measure the neutral and electron density profiles, the RO is proposed. The instrument is microwave transmitter (or receiver as per option) on board, operating at X-band frequency and it can provide the bending angle due to the Martian atmosphere. It can help understand the behaviour of the Martian atmosphere.

To characterize SEPs and supra-thermal solar wind particles at the Martian environment and to understand their role in the loss of Martian atmosphere. This instrument will measure high-energy charge particles in the energy range of 20 keV to 20 MeV.

To measure electron number density (Ne), electron temperature (Te), electric field waves in order to understand the Martian plasma environment. LPEX experiment consists of one Langmuir probe (LP) and two electric field (EF) sensors each mounted on a long boom.
