MOSCOW — In an embarrassing failure that capped a tense day, two Mir cosmonauts canceled a spacewalk Tuesday because they ran out of wrenches and into several minor problems aboard the aging space station.
The Russians, Nikolai Budarin and Talgat Musabayev, were unable to open the hatch leading to outer space after breaking all three of their wrenches.
Officials said the spacewalk will probably be rescheduled for April, adding that more wrenches could be sent to Mir on the next cargo ship.
"One of the locks was closed so tightly that . . . Budarin, a physically strong man, broke three [wrenches] and still failed to open the last of 10 locks," Mission Control chief Vladimir Solovyov said.
