Why on Earth would you help them militairise outerspace and draw a crosshair on your forehead while being at it ?
As if current spacejunk isn't enough of a threat to humanities future in space already. This sounds all awesome at first, but think about it for a second.

I read a paper about that. It said that 98% of the energy emitted at that frequency is absorbed by oxygen, and this was touted as a benefit, because it effectively “insulated” the towers, so they would not interfere with each other. But I am still surprised that any engineer would design a system that is only 2 percent efficient.
At scale all radio is absorbed by something... mostly not your recipient's antenna.
or continues propagating into the endless depths of space

#33My work focuses primarily on consumer application development, however cybersecurity and CTF challenges like this have always been an interest. What specific technical skills are required to successfully complete challenges like this?
Have you ever had to debug a "blackbox" before, Application code or hardware that you had really nothing to do with and had to figure out how in the hell it works? or worked with embedded devices or embedded radios? Would love to help you out likewise anyway, hit me on up twitter @JRWR

Because they would do it anyway. I've heard "stories" of attackers gaining control of a sat, "flipping it" to prevent it from listening to incoming commands, and then asking for a ransom from the original owners.

I'd argue that "Team Leader" means "boss," though.
In the hackathon environments I've been in there isn't really an organizational hierarchy per team. Team Leader really means Team Representative; i.e. they only want one person coming up to give/receive items/documents/information, so they ask each team to pick a leader who can interact with the event staff.

#37Is there a pointer on where to read more about challenges like this - technical information on how space com systems work, and what some example CTFs are?

#38Hello. My CS experience is quite elementary, and I'm a decent enough Web Dev and Scientific Programmer. If I wanted to be the type of hacker capable of taking down a Satellite, what would be everything that I would need to learn? I assume that this is super complex (Duh) but am curious as to the actual extent of knowledge required to pull this off.

Kind of annoying timing, to be honest…

#40Is the target an actual satellite in space, or is it on the ground / simulated?
