The single biggest problem that any team is facing is getting cash and sufficient cash to pay for a launch. This has been a problem for Astrobotic (and why they have postponed to 2015). This has been an issue for Moon Express. This is an issue for Rocket City Space Pioneers. And, yes, it is an issue for Team Phoenicia (my own team). For FredNet, too.
Getting material donations has not been difficult. Just the $. That's why Team Phoenicia has been selling engines and rockets.
If you want to help and not just snark, go to your favourite team's website and hit the donate button. They all have them. If /. or any other entity would use the /. effect to that end, it'd be a wondrous and helpful thing.
