That rocked, as we approached the back of the building some kind of fog was oozing out onto the ground like it was a hollywood set or something. Company will be in the news next week.
- The SV will seperate from the rocket via explosive bolts ( 2001 spaced odyssey-esq )
- Hydrozene is the fuel not benzene
- A rock-n-roll road crew comes in and blasts the SV during acoustic testing
- Vibe testing along with vacuum and thermal testing round out the major physical tests
- The SV will operate at room temperature since nearly all testing was done at room temp
- 2 money-pipes transmit the data one at a time, 2 for redundancy
- 2 star trackers for accuracy and redundancy
- Orbit decay results from solar wind + drag from flying into minute particles, molecules
- QB02 lasted beyond mission life because forecast solar winds exceeded actual solar winds
- Despite the cold of space, without molecular atmosphere radiant cooling is possible but convective cooling is not
- Hydrozene is used solely to correct decaying orbit, ignites at low temps
- Internal gyros allow the satellite to quickly retarget image strips, assume its using electric pwr from solar panels
- Part of the shroud is for temperature control, part of it is for blocking unwanted light
- Unlike deep space telescopes, WV02 does not need a long scope, it needs a fat scope to capture more light
- It is unheard of to have a successful launch and a failed satellite due to damage from vibration
- It is unheard of for a satellite to have damage from space junk but likely from our own junk that we put into orbit.
This thing is supposed to go launch from Vandenburg in September. Nobody is getting their contract extended beyond the launch date, if all goes well I expect to get resigned.
SV is sensor vehicle.
The high-resolution satellite was able to image the rocket's vapor trail and the flame-plume of the rocket itself as it headed east toward Japan.
