India planning Venus mission - The Times of India 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.
