The STS94/Columbia landed at the Kennedy Space Center (KSC) in Florida on 17 July after its flawless 16-day reflight of the Microgravity Space Laboratory, with more than 30 high-technology materials, protein crystal and other experiments similar to those which will be operated on the International Space Station.
The Columbia had returned to space on 1 July, 84 days after its last landing at the end of the original STS83 mission, which was aborted by a fuel-cell shutdown in April (Flight International, 16-22 April). The United Space Alliance processing team achieved a 56-day turnaround in the KSC Orbiter Processing Facility. It was also the first time that the same crew was launched into space a second time, and a record 84-day return to orbit for any space traveller.
