NASA's newest lunar probe now has a longer lease on life, giving it more time to investigate the mysteries of moon dust as it orbits Earth's natural satellite.

Space agency official have granted theLADEE spacecraft(short for Lunar Atmosphere and Dust Environment Explorer) a 28-day mission extension. Scientists will use the additional time to make different measurements of lunar dust in the moon's thin atmosphere from a lower orbit than LADEE has used before, NASA representatives said.

"The science team has already established a baseline of data for the tenuous lunar atmosphere, or exosphere, and dust impacts," Rick Elphic, LADEE project scientist, said in a statement. "One cool thing about this extension is that we plan to fly LADEE at only a few kilometers above the lunar surface. This will be much lower than weve been before."

LADEE launched to the moon on Sept. 6, 2013 on a mission to investigate the nature of moon dust and solve a long-standing mystery dating back to before the Apollo program.

Scientists are trying to uncover what caused a glow Apollo astronauts saw on the lunar horizon before sunrise. Researchers expect that magnetically charged dust in the moon's exosphere is to blame for the unexpected glimmering. However, LADEE is designed to collect more data on the subject.

LADEE started science operation on Nov. 10, 2013 and originally, the couch-sized spacecraft was only expected to conduct 100 days of science around the moon. But the probe has enough fuel to collect another lunar cycle's worth of data before crashing into the moon's surface. LADEE is now expected to impact the moon on April 21 of this year.

"The launch vehicle performance and orbit capture burns using LADEE's onboard engines were extremely accurate, so the spacecraft had significant propellant remaining to enable extra science," Butler Hine, LADEE project manager at NASA Ames in California, said in a statement. "This extension represents a tremendous increase in the amount of science data returned from the mission."

For most of human history, the moon was largely a mystery. It spawned awe and fear and to this day is the source of myth and legend. But today we know a lot about our favorite natural satellite. Do you?
