It is very difficult to get into ISRO and only a few very good students get a chance. To do a PG in Astronomy and Astrophysics, your friend would need a B. Sc. in Physics. But he can straightaway do a Ph. D in Theoretical & Observational Astronomy, Astrophysics, Planetary, Atmospheric & Space Sciences. These programs are offered at Indian Institute of Astrophysics, Bangalore (www.iiap.ernet.in), Inter University Centre for Astronomy & Astrophysics, Pune (www.iucaa.ernet.in), National Centre for Radio-Astrophysics, Pune (www.ncra.tifr.res.in), and at Jawaharlal Nehru Centre for Advanced Scientific Research, Bangalore (www.jncasr.ac.in). For enrollment in these programs, he will have to appear in the Joint Entrance Screening Test (JEST) conducted by the Indian Institute of Astrophysics, Bangalore.
