To test data integrity, the sender of the data calculates checksum value by taking the sum of the binary data transmitted. When receiving the data, the receiver can perform the same calculation on the data and compare it with the checksum value provided by the sender.
Venusâ atmosphere is much thicker than Earthâs, preventing a clear view of the planet. Its atmosphere is dominated by carbon dioxide, and features swirling clouds of sulfuric acid. The atmosphere on Mars is also dominated by carbon dioxide, although unlike Venus, it is quite thin. Gas giants are composed of gases.
The atmosphere of Venus is made up almost completely of carbon dioxide, with traces of nitrogen. Much of the hydrogen in the atmosphere evaporated early in the formation of Venus, leaving a thick atmosphere across the planet. At the surface, the atmosphere presses down as hard as water 3,000 feet beneath Earth's ocean.
