| 内容記述 | A definite deceleration of the comet probe Giotto due to drag in the comet Halley atmosphere has been noted by means of Doppler and ranging measurements based on the radio signals of the Giotto spacecraft. The total radial velocity change is 16.7 cm/s over a 100-s interval; this corresponds to a Doppler frequency of 4.7 Hz. This velocity change is used to estimate a total cometary mass striking the spacecraft of between 0.1 and 1.0 g. |
