President Nixon Greets the Returning Apollo 11 Astronauts

President Nixon Greets the Returning Apollo 11 Astronauts
The Apollo 11 astronauts, left to right, Commander Neil A. Armstrong, Command Module Pilot Michael Collins and Lunar Module Pilot Edwin E. "Buzz" Aldrin Jr., inside the Mobile Quarantine Facility aboard the USS Hornet, listen to President Richard M. Nixon on July 24, 1969 as he welcomes them back to Earth and congratulates them on the successful mission. The astronauts had splashed down in the Pacific Ocean at 12:50 p.m. EDT about 900 miles southwest of Hawaii. Apollo 11 launched from Cape Kennedy on July 16, 1969, carrying the astronauts into an initial Earth-orbit of 114 by 116 miles. An estimated 530 million people watched Armstrong's televised image and heard his voice describe the event as he took "...one small step for a man, one giant leap for mankind" on July 20, 1969. > Apollo 11 and NASA's Next Giant Leap Image Credit: NASA

Episodic Erosion
Episodic Erosion
24 Jul 2014
This image of the south polar layered deposits (SPLD) shows evidence of multiple episodes of deposition and erosion near the base of those deposits.

The SPLD, like the north polar layered deposits, are thought to contain a record of global climate changes on Mars. The surface of the outcrop shown here slopes generally toward the right. The layering at the bottom of the image is cut off by deposits that partly fill two broad valleys that were previously cut into the SPLD, probably by wind erosion. These more recent deposits appear to cover the flatter, upper part of the SPLD at left, and have also been eroded to expose layering with them.

Zucchius Peaks
Zucchius Peaks
24 Jul 2014
Even to the naked eye, our Moon looks heavily cratered. The snippet of carved and pitted lunar surface shown in this image lies within a 66 km-wide crater known as Zucchius. From our perspective, Zucchius is located on the edge of the southwest limb of the Moon.

The crater?s uneven and messy appearance is a result of how it formed. Lunar craters like Zucchius were created when rocky bodies, such as, meteors and asteroids, collided with the Moon at speeds of tens of kilometers per second, smashing holes into its surface. More forceful impacts caused material to spring back upwards, a bit like a water droplet hitting a body of water. This process formed a peak in the center of the impact crater, as shown here by the cluster of bobbly mounds.

Zucchius?s central peak and other features are quite well preserved. They are thought to have formed in the last 1.2 billion years, a time dubbed the ?Copernican period?. This is very recent compared to the Moon?s age of 4.4 billion years.

Earth was also cratered in this way ? were it not for our planet?s different conditions it would look a lot like the Moon. Plate tectonics, the atmosphere and the presence of liquid water have all contributed to changing the shape and appearance of Earth?s surface over time, eroding, covering and smoothing away surface blemishes.

This image was taken with the Advanced Moon Imaging Experiment on board ESA?s SMART-1 on 14 January 2006, as the spacecraft skimmed just 753 km above the Moon?s surface. Zucchius was named after the 17th-century Italian astronomer Niccol Zucchi, who was involved in some of the first designs for the reflecting telescope, and who made early observations of Jupiter\'s belts and spots on Mars.
