Maybe China will use it to test something before it falls down. Nothing that I see from China on this satellite. Maybe China will use it to test something before it falls down.

The expect lifetime of the satellite is just 2-3 years. So, the satellite definitely retired. This the first Chinese SAR satellite. The expect lifetime of the satellite is just 2-3 years.

The orbit is high enough that it will take some time for the pieces to decay. There’s no (unclass) word on what type of thrusters/propulsion are used, as far as i know. Preliminary analysis points to a propulsion failure as the reason for the breakup. I note 3 newly catalog-able debris piece. Pi-

Is there any type of fuel like hydrazine on this kind of satellite? Let’s hope that the possible fuel won’t become an excuse to shoot down the satellite. President Obama is going to meet His Holiness soon. Will some of the debris fall down? Is there any type of fuel like hydrazine on this kind of satellite?
