The astronauts aboard the linked space shuttle and space station are nearly finished packing up a moving van for return to Earth in a few days. The Italian-built van - essentially a giant cylinder - flew up aboard Discovery with seven tons of space station supplies and equipment. It will come back filled with a ton of trash, surplus gear and completed science experiments. The astronauts will place the van back aboard Discovery Monday night, just in time for Tuesday's shuttle undocking. On Sunday, the 13 space fliers got the night off after a week of virtually nonstop work together. Discovery is due back at Kennedy Space Center Thursday.
