Stu Grissom, manager for project development of hardware at NASA's Johnson Space Center, said NASA was evaluating mechanical difficulties with a Russian-made docking device critical to plans for a first linking of a Space Shuttle to the Mir Space Station in mid-1995. NASA was surprised to learn earlier that the Mir side of the docking device had explosive charges on only the active hooks whereas the Shuttle side had charges on both the active and passive mechanisms. The second problem was the failure of a laboratory version of the Shuttle/Mir docking mechanism to fully pass two of five cold temperature runs in June at NPO Energia (a subcontractor to Rockwell International) facilities in Russia. The failure, which was being investigated, might be the result of the quality of lubricant used. (H Chron, Jul 2/94; H Post, Jul 2/94; Av Wk, Jul 4/94)
