HRSC Press Release #384 - Nepenthes Mensae (orbit 5212)
]')) Perspective view #1 |
On 22 January 2008 the High-Resolution Stereo Camera (HRSC), under the leadership of the Principal Investigator Prof. Dr. Gerhard Neukum of Freie Universitaet Berlin, onboard the ESA spacecraft Mars Express obtained image data in orbit 5212 with a ground resolution of approximately 15 meters per pixel. The data were acquired in the region of Nepenthes Mensae at approximately 3° northern latitude and 121° eastern longitude.

The southern part of the image shows a peculiar structure reminding of a river delta on Earth (1). Its material was eroded from an approximately 30 km long and up to 1000 Meter deep valley (2). The material then formed a fan-shaped deposit at the mouth of the valley. The rim of the deposit stands roughly 300 Meters above the floor of the depression.
]')) Context Map |
The resemblance to river deltas on Earth suggests a similar formation mechanism, where water-transported sediment is deposited as the flow velocity decreases due to the widening of the channel at the mouth of the river. The type of delta cannot be determined from this image, as no cross-section of the deposit is exposed.

Two flood phases can be distinguished. One phase left a cone-shaped deposit, reaching far out into the lowland. The other fan with the distinct margin was formed in a different phase. This margin could indicate flow into a standing body of water or ice.
