For resources and capabilities, Earth Station is the largest communications array ever built by man. It is capable of coordinating messages from Tokyo, Vienna, Berlin, Washington DC, and Babylon. It can then route those messages out to Mars, the Moon, Io, or whatever scientific mission is occuring in another part of space. It also is capable of sending out thousands of probes into deep space and monitoring their signals, and it is still recieving some messages from probes sent out before 2012
We have a catapult system set up to ship cargo to the Moon, Mars, and Io if the need be, although the receiving end of the Mars catapult is not functional.
We have bunk space for 525, although not the resources to support them for long. We have supplies and replacement parts that should last us for the next 10-50 years, although food supplies will run out closer to the 10 year mark due to spoilage.
We have 4 operational shuttles:
Gabriel is configured for Exploration, and is the only one with 4 hardpoints. It can handle 2 crew, 8 passengers, and about 240m^3 of cargo with the lighter robotic arm.
Raphael is configured for Satelite Repair, and has a stronger robotic arm, more tools, and has a real airlock for spacewalks. It can handle 6 crew, and about 160m^3 of cargo.
Jophiel is configured for Earth Gravity cargo. It can handle a crew of 2 and about 320m^3 of cargo. It is different than Gabriel and Raphael in that the cargo hold is designed for earth gravity and it does not have a robotic arm. It is more easily loaded by truck however.
Chamuel is configured for long range human transport. It can be adjusted to either ship 6 crew and 122 passengers for short trips, such as from earth to Earth Station. Or it can be configured to handle 6 crew and 26 passengers for trips of multiple weeks. Hot-bunk rotations can double that number, but more than that would stress the life support systems.
Maximum tonnage of systems and cargo is 65,000 tons. Those shuttles with more cargo capacity are best if the cargo is approaching the maximum.
We have about 6 satelites in communications with Aleph currently, 2 of them are equipped with downward facing cameras, the other 4 are used to bounce communications around the planet.
We have significant ore stockpiles on the Moon, including refined Uranium, Iron, and a few other metals. With significant effort we can also get the Moon human habitable again and restart mining operations, but that could take years. The Uranium is estimated to run out in about 20 years, faster with more shuttle trips, unless we find another source to keep Earth Station running, or we shut down Moon Base to conserve.
Communications with Mars has been lost, but it once held a colony of about 20,000 people. When the food ran out in 2012, they had something of a violent response, and we don’t know what shape anything is in. They would have hundreds of shuttles and everything that people who were planning to live in a location forever would bring, but neither Al nor I have properly scouted. There is a possibility that someone could still be there, but that chance is small.
Io was just a scientific base, and it has little for resources and has been abandoned. It is also significantly harder to get to.
 It is possible that the Moon and Mars are technically separate threads. We have not seen enough evidence to know one way or another, but what we recall about them, especially Mars, may not still be true. If the Moon is a separate thread, it has a large open gate with Earth Station along the Catapult and communications path.
