By 1922 there had been significant advances in technology, especially in transport and communications. Now, there were reliable aircraft and motorised vehicles that could extend the range and ease of Antarctic exploration.
Radio could be used to stay in touch with expedition members and with the faraway outside world, making Antarctica less remote and less dangerous. Nutritional knowledge had also improved, finally banishing the disease of scurvy which had afflicted the earlier expeditions.
People like Sir Hubert Wilkins, Admiral Richard E. Byrd, and Lincoln Ellsworth would expand our knowledge of Antarctica from the air, achieving a number of firsts in Antarctic exploration, while men like Mawson, Rymill, and Ronne would conduct well-planned scientific or exploratory expeditions on land.
By 1950 we were beginning to enter the Modern Era of Antarctic exploration, also known as the Age of Science and Exploration. In this era we would see the founding of permanent Antarctic bases, a focus on science and the mapping and exploration of the unknown sections of the Antarctic.
