TIRUPATI: An Indian scientific mission to Venus is being considered by the space community. This was announced by M S Anurup of Isro at the 17th National Space Science Symposium which has been jointly organised by Isro and Sri Venkateshwara University.

According to Anurup, a preliminary study had indicated that if this mission gets the go ahead and depending upon the orbital parameters, it could be launched on May 20, 2015 arriving in Venus in October 2015. There could be about five scientific instruments on board the Venus-bound spacecraft. The rocket could either be the advanced version of the Polar Satellite Launch Vehicle (PSLV-XL) or the Geo Synchronous Satellite Launch Vehicle (GSLV) or the newer version of the GSLV designated as GSLV Mark3.The preliminary study states that the main role of the Indian mission to Venus would be to study its atmosphere. It will also help to examine the origin and evolution of terrestrial planets.

The report has expressed confidence that based on the success of the Chandrayaan-1 mission, India has the capability to launch a mission to Venus. In addition, with the launch of Risat-1 satellite next month, India will possess a radar imaging capability which will be necessary for the Venus mission. In another recent development, scientists of the Ahmedabad-based Physical Research Laboratory (PRL) have reported the existence of a cavity on Mars for the first time measuring 500 metres by 100 metres.

This was announced by them at the Tirupati space meet through a poster. The project which was based on the data obtained from Nasa Mars Reconnaissance Orbiter (MRO) was jointly done by SVS Murthy and Rishitosh Sinha of PRL. Sinha said the newly-found cavity is bowl shaped and is located at the foot of a crater hill.

Does not sound unattainable, provided our spacecraft lives long enough. It takes months to reach Venus. If we use lower powered vehicle like the PSLV, it could take quite a while.

Timeline for Magellan mission:
04 May 1989 - Launch
10 Aug 1990 - Venus orbit insertion and spacecraft checkout
15 Sep 1990 - Cycle 1: Radar mapping (left-looking)
15 May 1991 - Cycle 2: Radar mapping (right-looking)
15 Jan 1992 - Cycle 3: Radar mapping (left-looking)
14 Sep 1992 - Cycle 4: Gravity data acquisition
24 May 1993 - Aerobraking to circular orbit
03 Aug 1993 - Cycle 5: Gravity data acquisition
30 Aug 1994 - Windmill experiment
12 Oct 1994 - Termination experiment - loss of signal
13 Oct 1994 - Presumed loss of spacecraft

Anything that enters Venus's atmosphere would be toast because of the temperature & gasses in their atmosphere.
The mission would probably be limited to orbiting around venus.

The atmosphere of Venus is much denser and hotter than that of Earth. The temperature at the surface is 740 K (467 °C, 872 °F), while the pressure is 93 bar.[1] The Venusian atmosphere supports opaque clouds made of sulfuric acid, making optical Earth-based and orbital observation of the surface impossible.
None of the Venus probes lasted long, none ever returned

Venera-9

We need a powerful rocket and I doubt if PSLV is a good platform.

The first successful space vehicle was the Soviet Proton Rocket that took the Venera 9 to Venus.

Here is a nice video animation of that mission:

Here is a picture of the Proton Rocket.

i thought it will be better to master cryogenic tech first before jumping to other planets. let our geo-synchronous satellites be taken to safe orbit first
