Vigyan Prasar EduSAT Network is in the process of up gradation. The hub is being shifted to Delhi from Ahmedabad. As the process of upgradation was ongoing we could not undertake any multicast during July – September 2008. The work related to up-gradation is yet to be completed.Multicast will commence subsequently. The new dates for the Quiz programme on Planet Earth will also be intimated to all centers shortly.
