Dear Mani and Suresh, This is the culmination of an important phase of 'Ham-History' of India. 'HAMSAT VO-52' was a dream fulfilled; an emotional outcome of many contributors and well-wishers. I would like to join you all in thanking and expressing heartfelt gratefulness to all those who made it possible to realize HAMSAT VO-52. May we all hope and pray for the next phase of 'Ham-India in Space' sooner than later; with higher power and in higher orbit.
