[amsat-bb] Re: Nanosatellite Launch Service 6 on PSLV-C15

[Daniel Kekez]

Hi All,

As you may have heard, the PSLV-C15 flight has been delayed. The Indian
Space Research Organization issued the following statement:

	The launch of ISRO's Polar Satellite Launch Vehicle (PSLV-C15)
	fixed for may 9, 2010 has been rescheduled. A marginal drop in
	the pressure in the second stage of the vehicle was noted
	during the mandatory checks carried out on the PSLV-C15
	vehicle. The new date for the launch of PSLV-C15 mission will
	be decided after preliminary results of the analysis are
	obtained.

	PSLV-C15 is planned to launch India's Cartosat-2B, an Algerian
	satellite ALSAT-2A, two nano satellites NLS 6.1 and NLS 6.2
	from the University of Toronto, Canada, and STUDSAT, a
	satellite built by students from academic institutions in
	Kamataka and Andhra Pradesh.

NLS 6.1 refers to AISSat-1 and its XPOD separation system. Similarly,
NLS 6.2 refers to TIsat-1 and its XPOD.

Since I believe some people on this list are looking forward to
receiving TIsat-1's beacon, I'll post updates when we learn more.
