The Odyssey orbiter has been hovering above Mars, photographing its surface and taking data for 16 years now. There’s seemingly infinite combinations of things to study and instruments to study them with—this time, all NASA had to do was turn the camera around.

Odyssey snapped its first photos of the tiny Martian moon, Phobos, with its Thermal Emission Imaging System (THEMIS) on September 29th. The moon is only 14 miles in diameter (around the width of Washington D.C.), and the images were taken from a distance of around 3,500 miles, the distance from New York to London.

NASA Fires Rocket High Above U.S. East Coast to Test Supersonic Parachute for Mars

  NASA Fires Rocket High Above U.S. East Coast to Test Supersonic Parachute for Mars Early Wednesday morning, NASA launched an unmanned rocket on a course high above the U.S. East Coast, as it does with some frequency.  1/3 SLIDES © NASA-TV Wallops 2/3 SLIDES © Provided by TIME Inc. 3/3 SLIDES © Provided by TIME Inc. Early Wednesday morning, NASA launched an unmanned rocket on a course high above the U.S. East Coast, as it does with some frequency. Unlike other such launches, however, this rocket wasn't trying to loft supplies up to the International Space Station, nor paint the sky with colorful artificial clouds.

Google' s unofficial motto has long been the simple phrase "don't be evil.". But that' s over, according to the code of conduct that Google distributes to its employees. The phrase was removed sometime in late April or early May, archives hosted by the Wayback Machine show.

You might be confused as to why this is news, since other orbiters like the Mars Reconnaissance Orbiter have taken snapshots of Phobos before. This is the first time Odyssey specifically has taken a peek at the moon, and the first infrared imaging available.

Odyssey normally looks at Mars with THEMIS, since the planet is only about 250 miles below. Normally, the orbiter works on its main goals—understanding the geology of the red planet, its water activity and whether it has or ever had life. But, according to a NASA statement, scientists only recently developed the maneuver to actually turn the orbiter upwards at the moon, which orbits at an altitude of 3,700 miles.

As a thermal imager, THEMIS, takes surface temperature information. This is important for studying space stuff: Understanding how things heat and cool under sunlight could help researchers figure out what things like Phobos are made of, and therefore their origin story. It’s like trying to figure out what a stovetop pan is made of based on how quickly it cools.

Here's how Nasa plans to chase Neptune's moon Triton as it casts a shadow on Earth

  Here's how Nasa plans to chase Neptune's moon Triton as it casts a shadow on Earth <p>Nasa is currently studying and analysing Neptune's largest moon Triton with the help of the flying telescope Stratospheric Observatory for Infrared Astronomy (Sofia), after the planetary body cast a faint shadow on the Earth on Thursday (5 October).</p>Nasa shared the specifics about how they plan to go about the mission in a post on Tumblr. Even though the event has already taken place, Nasa is yet to divulge any details about whether its mission was successful.

Mars’ moons are weird. They’re tiny, pathetic potatoes compared to moons like ours or Titan, Saturn’s moon that’s bigger than even planet Mercury. But some scientists think that once in the planet’s past, it had a ring system like Saturns’ that coalesced into moons—and will one day turn into rings again. After all, Phobos is literally falling apart.

The universe is full of new things to study. But sometimes you just gotta turn around first.

Huge cave found on moon, could house astronauts: Japan scientists .
Scientists have discovered a huge moon cave that could one day house a base that would shelter astronauts from dangerous radiation and wild temperature swings.Data taken from Japan's SELENE lunar orbiter has confirmed the existence of the 31-mile-long and 328-foot-wide wide cavern that is believed to be lava tube created by volcanic activity about 3.5 billion years ago.
