 To seal the module, the crew had to remove the cables that were routed through the (open) hatchway, including the power cables from Spektr's solar panels.An internal spacewalk in the Spektr module in August 1997 by cosmonauts Anatoly Solovyov and Pavel Vinogradov, from Soyuz TM-26, succeeded in restoring these power connections by installing a modified hatch cover to allow the power cables to pass through the hatch when it was in the closed position.In a second internal spacewalk in October they connected two of the panels to a computer system to allow the panels to be controlled remotely and align with the Sun.
