# Significant Ice Reservoir Discovered on Mars
Written on
Chapter 1: Discoveries of the Mars Reconnaissance Orbiter
The Mars Reconnaissance Orbiter (MRO) has been exploring the Red Planet since 2006, yielding remarkable findings along the way. Recently, it detected substantial evidence of a significant volume of water ice beneath Mars' northern ice cap, approximately 1.2 miles deep. This discovery provides insight into Mars' geological history, suggesting these ice deposits may be remnants of its ancient ice caps.
According to scientists, this newly identified reservoir is believed to be the third-largest accumulation of water ice on Mars.
Section 1.1: Ice Cap Insights
While it's well-known that Mars has surface ice caps, the MRO's radar instruments have unveiled a hidden treasure beneath them. If melted, this ice could inundate the entire Martian landscape with five feet of water. The American Geophysical Union, which released the findings based on NASA's data, indicates that the radar imagery reveals the ice stratified in layers interspersed with sand. This formation is predominantly composed of water ice, estimated to account for 61 to 88 percent of the total volume.
Subsection 1.1.1: The Importance of Layer Analysis
Geologists find layered formations particularly fascinating as they offer a glimpse into historical environmental changes. By studying these layers, scientists could uncover valuable information about Mars' climatic evolution, which is crucial for the ongoing search for signs of ancient life. This exploration aligns with the objectives of NASA's upcoming Mars 2020 rover mission.
Section 1.2: Implications for Future Exploration
Understanding the location of such a substantial water supply is essential for future human missions to Mars. Transporting all necessary resources from Earth can significantly inflate mission costs. Identifying in-situ resources, such as the vast water supply hidden underground, could determine the feasibility of human colonization on Mars.
Chapter 2: Challenges Ahead
The first video, "ESA's Mars Express orbiter discovers ice water deposits at the Red Planet's equator," delves into the implications of this substantial ice discovery and its potential for future missions.
The second video, "Mars: Exposed - Icy Revelations from the Red Planet," further explores the significance of these findings and what they mean for our understanding of Mars.
Despite the exciting potential of these ice reserves, accessing them is not straightforward. The ice is situated beneath the current ice caps, which consist of a mixture of water and carbon dioxide ice. Nevertheless, utilizing Martian ice may prove more practical than transporting water from Earth, especially with plans to establish human colonies, as envisioned by figures like Elon Musk.
