remote sensing - Great Lakes

Question

The A-train is a so-called constellation of objects used in this scientific field. For 10 points each:

[10m] Name this field exemplified by the use of Earth observation satellites. Active instruments in this field emit their own radiation, while their passive counterparts utilize existing radiation, such as sunlight.

ANSWER: remote sensing [or RS]

[10h] Sensors on remote sensing satellites are typically arranged in one of these two configurations. One utilizes a single detector moving back and forth, while the other uses a line of detectors to collect swaths of data. Name either.

ANSWER: whisk broom OR push broom [accept across-track or spotlight in place of “whisk broom”; accept along-track in place of “push broom”]

[10e] The single detector on a whisk broom scanner is able to scan back and forth by using a rotating one of these devices. The James Webb Space Telescope has 18 large, hexagonal, gold-plated devices of this type.

ANSWER: mirrors [accept reflectors or looking glasses]
