ISRO’s first planned mission to Venus will focus on understanding the geological
evolution of the planet using an S-band polarimetric synthetic aperture radar (VSAR) with a
capability to image the Venus surface at high spatial resolutions

 

[Swesh]

order to
obtain fundamental information on subsurface geology, a low-frequency radar sounder that can
obtain vertical resolutions of 5-15m along with surface penetration capability (up to 1 km
depth) is also proposed for ISRO’s Venus mission. Based on the results obtained from
Magellan mission and Earth-based radar mapping, we note below some of the significant and
compelling science questions that would be focused upon by the proposed VSAR and radar
sounder instruments:

“Lightning Instrument for VEnus (LIVE)

In LIVE, the lightning events are captured using antenna [3] and is further processed using
processing electronics. The front-end electronics has two configurations, where the first
configuration is PVO OEFD like architecture [4] having six channels for six different
frequencies and the second configuration has a wide band filter (Hz-kHz). All channels are
sampled simultaneously using an Analog-to-Digital Convertor at required sampling rate and
the digital data are stored in a memory for processing using FPG

Venus Thermal Camera (VTC) proposed by Space Applications Center
(SAC) operates in the 8-12 µm spectral range and has high-temperature sensitivity. Venus
Thermal Camera (VTC) has a NEdT of 0.1K at 230K. VTC will provide approximately 0.5 km
resolution from the periapsis and 60 km from the apoapsis (considering the typical elliptical
orbit of 500 km x 60,000 km). It aims to capture planetary-scale thermal features at the apoapsis
and fine features at the periapsis. The detector is based on a cooled MCT rather than a
Bolometer, so it can capture finer thermal features with exceptional NEdT performance. VTC,
with its high thermal resolution (better NEdT), will allow us to study cloud top temperature
variations globally in the Venusian atmosphere with more precision, contributing to long-term
data records of the atmospheric evolution of the Venusian atmosphere, which in turn will help
us to understand its dynamics (super-rotation). Furthermore, VTC will assist in studies
involving cloud-based processes, particularly diurnal variations.
