What it concludes
- The Parkes Radio Telescope is capable of handling heavy equipment in and out of its central part much more easily by letting the dish do the lifting.
- The polar axis calibration technique invented by Barnes Wallis allowed single-dish antennas to point very accurately across the sky.
- Radio telescopes must be exceptionally large to collect the extremely weak radio energy emitted by stars.
