Giotto's encounter with Halley's comet Giotto's HMC images of Halley's comet, captured on March 13 and 14, 1986, were complicated by the fact that its camera was a line-scanning or "pushbroom" instrument, while the spacecraft rotated. Near closest approach, the spacecraft took 74-pixel-wide images in rapid succession until the spacecraft suffered too much damage from Halley's debris. ESA / Giotto project, H. U.
