I'm curious to find out answers to the following questions:
Where is the antenna for the live feed transmitter of starman located in the payload?
How is the transmitter being powered?
Related to 2nd question, how long will the live feed last?
I noticed that this last question was asked from Elon during the news conference after the launch but it was left unanswered. I'm partly curious to find this out so I know how long I have before the incredible view of the earth in front of the roadster windshield goes dark :)
