Getting the ride to orbit after the second Finnish satellite already got deployed *and* stopped working (Aalto 2 got to ISS on the Cygnus, was deployed and few weeks later ended up no longer responding to commands)Was originally booked on Falcon 9 along with Formosat, but moved to this rocket after SpaceX delays due to certain unfortunate event that kinda wrecked the schedule last autumn.

It can also be debated whether this is the first real Finnish satellite, as the QB-50 satellites are registered to the Netherlands regardless of their country of origin. But Horray! gotta wake up early tomorrow
"few weeks later.." For the historical record do you happen to know when exactly Aalto 2 stopped working? I would say Aalto 2 was the first Finnishsatellite (even if it will be UN-registered by Belgium).Good luck with Aalto-1.
HYDERABAD: India's 'eye in the sky' is set to become sharper and wider with the launch of a third spacecraft in Cartosat-2 series -- a dedicated satellite for defence forces -- from the Sriharikota spaceport tomorrow.
The previous satellite in the series had a resolution of 0.8 metres. The latest remote sensing satellite slated to be launched on board PSLV-C38 tomorrow morning has a resolution of 0.6 metres, which means it can spot even smaller objects.
"It can recognise objects within that square (0.6 m by 0.6 m)", an ISRO official told PTI on condition of anonymity.
Once this satellite becomes operational, it would be "handed over" to the defence forces, which have their own "set up," including ground-stations and trained manpower to access data.
On the need to have a third satellite in the series, the official said, "The revisit time is the one which determines your data accessibility. More the number of satellites, the better and shorter revisit time you will have and more data you will get."
Mobile Service Tower (MST) withdrawal to parking end is completed. Preparations for propellant filling operation of Second Stage (PS2) are in progress

The report quotes an anonymous source, so there is a certain level of confusion with the intended use of this bird. Unlike the previous two 'Cartosat 2 Series' namesakes, this was often featured in many ISRO presentations (with a proper name as 'Cartosat-2E') indicating it was likely a civvie, while references to the former two were often avoided. But now this too got the official name as 'Cartosat 2 Series'.

So yeah, to my mind its really a question of whether it is a normal 'dual-use' Cartosat or a 'military-only' one as its two predecessors (or four considering that both 2A and 2B too have been rumoured to be dedicated for 'strategic users').

“Once the last satellite has been separated from the rocket at a height of 520 km, the fourth stage of the rocket (PS4) comprising two liquid propellant engines will be shut down and reignited three times,” Mr. Jayakumar told The Hindu. While the first two firings are expected to last about six seconds each, the third restart is likely to fire up to 40 seconds.The multiple reignition of the on board engines will validate the technique and provide ISRO with the mission flexibility to inject satellites into three different orbits in a single flight to reduce the launch cost and save time.
Propellant filling operations of Second Stage (PS2) are in progress
Propellant filling operations of Second Stage (PS2) are completed. Countdown is progressing normally.
