      AstroSat, India’s first astronomical observatory was launched on 28th September 2015 by PSLV into an orbit of altitude 650 km and 6$^{\circ}$ inclination. The simultaneous observations made by the payloads allow imaging of celestial source in various wavebands and has resulted in scientific achievements published in various fora. AstroSat is designed to carry 6 ($5+1$ auxiliary) astronomy payloads namely, UVIT, LAXPC, SXT, CZTI, CPM and SSM. The payloads are mounted such that the boresight of all the 4 main payloadsexcept SSM are along the $+$Roll direction in body frame. To meet all requirements of different payloads carried on-board AstroSat, various mission planning, analysis, and operations specific to this mission are carried out. These include post launch observations and mitigations planned and implemented onboard.

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
