Japan launches new intelligence-gathering satellite

The launch, previously set for Jan. 28, was pushed back due to a leak in piping used to supply the rocket with nitrogen gas

I looked through the H2A User Manual to see what the Nitrogen is used for, but am no wiser.

Any clues?

Nitrogen has a long association with rocket fuelsand explosives, such as nitroglycerine and TNT (trinitrotoluene). This is because nitrogen gas, N2, is extremely stable.

What is "intelligence" without intelligence.

”Military intelligence” an oxymoron.

Intelligence without intelligence? Look to the administration in Washington DC for a perfect example.

Congratulations NSADA and the H2A program. I went to Tanegashima to witness a launch once. It was an earthmoving experience.
