ISRO Launched ‘Pratham’ IIT-Bombay Student’S Satellite Using PSLV [ Current Affairs - Science & Technology ]


The Indian Space Research Organisation (ISRO) successfully launched ‘Pratham’ a miniature satellite designed by IIT Bombay students. ISRO also launched seven other satellites into two different orbits in a single mission. This concluded the longest and most complex mission.

  • All the satellites were launched by Polar Satellite Launch Vehicle C35 (PSLV C35) from the Satish Dhawan Space Centre, Sriharikotta.
  • Three satellites were from India, three from Algeria and one each from Canada and United States.
