The meteoroids can hit the lunar surface at velocities greater than 21 miles (34 kilometers) per second, converting their kinetic energy into intense heat and vaporizing part of the lunar regolith as well as the meteoroids themselves. The massive strike can turn their kinetic energy into heat and vapor. It sends images back to Earth in four passes per day of 310 gigabits each, or 155GB per day in total.

Wearing handcuffs and beige T-shirt, Marquez appeared in federal court in Riverside, California for a brief hearing on Thursday. Apparently it was a marriage of convenience , and a sham in order to get the woman in question American citizenship.
These frequent readings revealed a rise in gas levels whenever meteor streams bombarded the Moon, with concentrations of both elements returning to normal levels after the stream had passed. Out of the two gases, potassium returned to earlier level within days and sodium took many months.
Hiddink arrives in London, confirms Chelsea talks
The Blues qualified for the knockout stage of the Champions League last week, and will host Sunderland on Saturday. Meanwhile, Chelsea captain John Terry has described Mourinho’s exit after 30 months in charge as a “sad, sad day”.
LRO is managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for the Science Mission Directorate at NASA Headquarters in Washington.
As we mentioned earlier, the process is quite complicated: the spacecraft has to snap images while it’s moving, and while the Earth and the moon are also in motion.
The Sahara Desert appears illuminated just to the right center. The South American coast is visible on the left, The Arizona Republic reported. NASA’s Lunar Reconnaissance Orbiter (LRO) mission has been investigating the lunar surface since 2009.

The high-resolution Narrow Angle Camera (NAC) on LRO takes black-and-white images, while the lower resolution Wide Angle Camera (WAC) takes color images, so you might wonder how we got a high-resolution picture of the Earth in color. The manuever involved the spacecraft rolling 67 degrees to the side and then slewing with the direction of travel to maximize the width of the horizon – while traveling faster than 3,580 miles per hour.
