Indian scientists have indigenously designed and developed a low-cost optical spectrograph that can locate sources of faint light from distant quasars and galaxies in a very young universe, regions around supermassive black-holes around the galaxies, and cosmic explosions.
Such spectroscopes were so far imported from abroad involved high costs. The ‘Made in India’ optical spectrograph, named as Aries-Devasthal Faint Object Spectrograph & Camera (ADFOSC), designed and developed by Aryabhatta Research Institute of observational sciences (ARIES), Nainital, an autonomous institute of Department of Science and Technology (DST), is about 2.5 times less costly compared to the imported ones and can locate sources of light with a photon-rate as low as about 1 photon per second.

The Indian Space Research Organisation (ISRO) on Friday (12 March) launched a sounding rocket (RH-560) from Andhra Pradesh s Sriharikota-based Satish Dhawan Space Centre (SDSC) to study the attitudinal variations in the neutral winds and plasma dynamics, reports
Times of India.
The sounding rockets are one or two-stage solid propellant rockets and are used to probe the upper atmospheric regions and for space research.
These rockets also serve as affordable platforms to test or to prove prototypes of new components or subsystems which are intended to be used in launch vehicles or satellites.
ISRO currently has three different versions of sounding rockets, namely RH-200, RH-300-Mk-II and RH-560-Mk-II, which are capable of carrying 8 to 100 kilogram of payload to an altitude varying between 80 to 475 kilometres from the ground.
