This week, we’re going for something a little different: this is the first photo from the Deep Space Climate Observatory Satellite, aNOAA Earth observation and space weather satellite launched by SpaceX on a Falcon 9 launch vehicle on February 11, 2015 from Cape Canaveral. This is the Earth in 2015, as seen from outer space. It’s a remake of the famous

GeoPicture of the Week: Mount Fuji from the ISS

Sometimes, astronauts onboard the ISS captures some stunning pictures. Here, we see Mount Fuji, the highest mountain in Japan, an active stratovolcano. Mount Fuji is located at a triple tectonic junction, where the Amurian Plate, the Okhotsk Plate, and the Philippine Sea Plate meet – an extremely volatile geologic area.

In geology, grabens are depressed blocks of land bordered by parallel faults. In German, “graben” means trench or ditch, and that’s a pretty good name for it. Graben are produced from parallel normal faults, where the hanging wall is downthrown and the footwall is upthrown; the faults dip towards the center.

This is how the Moon looks under the microscope!

The Apollo program returned 380.05 kg of lunar rocks and soil, and most of the samples are stored at the Lunar Sample Laboratory Facility. The samples of rocks, breccias, and regolith were polished into thin sections, allowing for optical geologic studies to be performed on them.

GeoPicture of the Week: Fresh Crater on Mars

mars-crater-from-above-nasa

This jaw-dropping image was taken by High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA’s Mars Reconnaissance Orbiter in the Sirenum Fossae region of Mars. This impact crater appears relatively recent as it has a sharp rim and well-preserved ejecta. The steep inner slopes are carved by gullies and include possible recurring slope lineae on the equator-facing slopes. Fresh craters often have

GeoPicture of the Week: The Seven Sisters of Sussex

The Seven Sisters are a series of chalk cliffs by the English Channel, in Sussex (doh!). In case you didn’t know, chalk is actually a porous sedimentary rock, a form of limestone composed of the mineral calcite forming in somewhat deep underwater conditions from the gradual accumulation of minute calcite plates (coccoliths) shed from micro-organisms called coccolithophores.   The southern and

GeoPicture of the Week: Turgite [aka unicorn dung]

Image source: Crystal Clear Radio.

Originally described from Turjinskii Mine (Turginsk Mine) in Russia, turgite is generally considered a variety of two more common minerals – goethite and hematite. Turgite is a mixture of the two minerals due to the alteration of goethite, typically found in the botryoidal (globular) habit of the “parent” goethite; however, because it is a mixture of two minerals, it is not considered a
