The Southern Cross Expedition embarked from London, representing the first British venture of the Heroic Age of Antarctic Exploration. Under the leadership of Carsten Borchgrevink, a Norwegian-born explorer, the expedition aimed to explore the uncharted territories of Antarctica and contribute to the understanding of this largely unknown continent. The ship, named Southern Cross, was well-equipped with provisions, scientific instruments, and a skilled crew, all set for an ambitious journey toward the South Pole. Borchgrevink's prior experiences in polar exploration equipped him with vital knowledge, which elevated the expedition's potential for success.

The expedition set a course for the Ross Sea, aiming to reach a location where a base camp could be established. This camp would serve as a launching point for various scientific observations and studies, including meteorology, geology, and biology, thereby adding to the scientific understanding of Antarctica. The concept of establishing a sustained human presence in Antarctica was revolutionary for its time, laying the groundwork for future exploration efforts.

Ultimately, the Southern Cross Expedition significantly influenced subsequent Antarctic explorations. The mission, although initially fraught with challenges, eventually led to discoveries that enriched scientific knowledge and incited further interest in the continent. The achievements of this expedition catalyzed later explorations and stimulated interest in the harsh, yet captivating environment of Antarctica, shaping the course of polar exploration in the years that followed.
