1080	2140	Challenge 4
3340	9100	Here's what we know. We've restored communication with the payload module, but we still can't operate it.
9100	14900	The challenge? Now teams must restore normal operations of the payload module so we can access the imager.
15220	20020	Here's how they do it. Teams discover that the payload module bootloader has been corrupted,
20020	23000	which is why the payload module is not operating normally.
23000	25700	The teams discover a system console to the payload module
25700	28740	and the ability to access the payload module system console
28740	34340	by controlling an undocumented GPIO and multiplexer on the CNDH board.
34340	38380	The teams must write a custom flight software application that can control the GPIO
38380	41500	and enable access to the payload system console.
41500	46400	After writing the application, the teams must upload it to the CNDH and execute it.
46400	51400	Once the teams have access to the system console, they will identify that it has been corrupted.
51400	54780	The teams will need to research nominal kubos bootloader configuration
54780	59340	and repair the payload module's bootloader to resume proper operation of the payload module.
