Can we tell the spacecraft to turn back on its thrusters and science instruments after decades of silence and perform the intricate ballet needed to send it back to where it can again monitor the Sun? Unfortunately the answer to that question appears to be no. 'The transmitters of the Deep Space Network, the hardware to send signals out to the fleet of NASA spacecraft in deep space, no longer includes the equipment needed to talk to ISEE-3. These old-fashioned transmitters were removed in 1999.' Could new transmitters be built? Yes, but it would be at a price no one is willing to spend. 'So ISEE-3 will pass by us, ready to talk with us, but in the 30 years since it departed Earth we've lost the ability to speak its language,' concludes Lakdawalla. 'I wonder if ham radio operators will be able to pick up its carrier signal — it's meaningless, I guess, but it feels like an honorable thing to do, a kind of salute to the venerable ship as it passes by.'"
The specific cause of the contamination is still under investigation but investigators also identified deeper causes, one of which involved what some accident-investigation specialists have dubbed the 'normalization of deviance' – small malfunctions that appear so often that eventually they are accepted as normal. In this case, small water leaks had been observed in space-suit helmets for years, despite the knowledge that the water could form a film on the inside of a helmet, fogging the visor or reacting with antifogging chemicals on the visor in ways that irritate eyes. NASA officials are not planning on resuming non-urgent spacewalks before addressing all 16 of the highest priority suggestions from the Mishap Investigation Board. 'I think it's a tribute to the agency that we're not hiding this stuff, that we're actually out trying to describe these things, and to describe where we can get better,' says William Gerstenmaier, associate administrator for NASA's Human Exploration and Operations Mission Directorate. 'I think that's how we prevent Columbias and Challengers.'"
