Space science missions

Space Capsule Recovery Experiment II The main objective of SRE II is to realize a fully recoverable capsule and provide a platform to conduct microgravity experiments on Micro-biology, Agriculture, Powder Metallurgy, etc. SRE-2 is proposed to be launched on board PSLV. Aditya (spacecraft) The First Indian space based Solar Coronagraph to study solar Corona in visible and near IR bands. Launch of the Aditya mission is planned during the next high solar activity period ~ 2012 but has been postponed to 2015-2016 due to the extensive work involved in the fabrication and other technical aspects . The main objectives is to study the Coronal Mass Ejection (CME) and consequently the crucial physical parameters for space weather such as the coronal magnetic field structures, evolution of the coronal magnetic field etc. This will provide completely new information on the velocity fields and their variability in the inner corona having an important bearing on the unsolved problem of heating of the corona would be obtained. The Space Capsule Recovery Experiment II (commonly known as SRE-2) is an Indian re-entry demonstration experiment designed by the Indian Space Research Organization. It is follow-on mission of SRE-1 which was successfully completed in January 2007. It will test some of the critical technologies for the Indian human spaceflight program. The second mission is to carry three experiments devoted to biological science and an improved isothermal furnace with 1000C temperature to carry out materials science experiments.[1]Aditya, (Sanskrit: , lit: Sun[3]) pronunciation (helpinfo) or Aditya-1 is a spacecraft whose mission is to study the Sun. It was conceptualised by the Advisory Committee for Space Research in Januar 2008.[2] It has been designed[4] and will be built and launched by the Indian Space Research Organisation (ISRO).[2] Former ISRO Chairman G. Madhavan Nair announced the approval of this mission on 10 November 2008.Spacecraft Aditya is proposed to be sent to space by 2015-16 to study the solar corona. This part of the Sun has temperatures of over one million degrees, with raging solar winds that reach a velocity of up to 1000 km a second. The satellite will carry as its payload an advanced solar coronagraph.[2][6] It will be a small 400 kilograms (882 lb) satellite projected to cost about 50 crore (US$10 million),[2] and likely to be placed into a near earth orbit of 600 km. The spacecraft's mission will be to study the fundamental problems of coronal heating, and other phenomena that take place in the Earth's magnetosphere. [edit]Objectives to study the Coronal Mass Ejection (CME) to study the crucial physical parameters for space weather such as the coronal magnetic field structures, evolution of the coronal magnetic field etc.[7] [edit]Progress This is one of the first scheduled projects in a road map formulated by the Advisory Committee for Space Research.[2] A working group of individuals from the ISRO Satellite Centre, Udaipur Solar Observatory, Indian Institute of Astrophysics, Radio Astronomy Centre, National Centre for Radio Astrophysics, and several universities.[2] was constituted to work out the optimum configuration for the coronagraph, among other parameters. The design of solar coronograph has been completed by Indian Institute of Astrophysics.[8] ISRO is working on development of sensors and thermal structures of the satellite after which a prototype of the satellite is expected to be built by 2011.
