Arty shot of moon crater with link to dinosaurs

The sun rises over the central peak complex of the moon’s Tycho crater in this image captured by NASA’s Lunar Reconnaissance Orbiter on 10 June.
The spacecraft, which has been collecting detailed information about the lunar environment since June 2009, angled its orbit 65 degrees to the west to capture the image.
Located near the moon’s south pole, the Tycho crater is about 85 kilometres across and 4.7 kilometres from floor to rim. The mountain range shown here is about 15 kilometres wide, left to right (south-east to north-west in this view), with its peaks rising 2 kilometres above the crater floor.
Some simulations suggest the crater was created by an impact from a fragment of the same asteroid family that caused the Chicxulub crater on Earth, which wiped out the dinosaurs.

Chicxulub crater, is an ancient impact crater buried underneath the Yucatán Peninsula in Mexico

At 108 million years old, Tycho is one of the moon’s youngest impact craters, and bright lines of ejected material – not yet eroded by the space environment – can be seen in other images streaking the moon’s surface.

Sunrise View of Tycho Crater’s Peak

leave a comment »

On June 10, 2011, NASA’s Lunar Reconnaissance Orbiter spacecraft angled its orbit 65° to the west, allowing the LRO Camera NACs to capture a dramatic sunrise view of Tycho crater.

Tycho crater's central peak complex, shown here, is about 9.3 miles (15 km) wide, left to right (southeast to northwest in this view).

A very popular target with amateur astronomers, Tycho is located at 43.37°S, 348.68°E, and is about 51 miles (82 km) in diameter. The summit of the central peak is 1.24 miles (2 km) above the crater floor. The distance from Tycho’s floor to its rim is about 2.92 miles (4.7 km)…. Read the rest of this entry »
