SUMMARY: The NASA/ESA SOHO spacecraft, which observes the Sun, is having problems pointing its high-gain antenna, which it uses to transmit data back to Earth. The cause of the problem hasn't been figured out yet, but experts think there's something wrong with its motor or in the gear assembly that steers the antenna - fortunately, its low-gain antenna is still working, so they can still communicate with the spacecraft. If they can't figure out the problem, SOHO isn't going to be able to transmit data back as quickly, so there will be blackout periods.
