Mars is no place for the faint-hearted. It’s dry, rocky, and bitter cold. The fourth planet from the Sun, Mars is one of Earth's two closest planetary neighbors (Venus is the other). Mars is one of the easiest planets to spot in the night sky – it looks like a bright red point of light.

Mars is the fourth planet from the Sun – a dusty, cold, desert world with a very thin atmosphere. Mars is also a dynamic planet with seasons, polar ice caps, canyons, extinct volcanoes, and evidence that it was even more active in the past.

Other notable features of the Venus landscape include: “Pancake” domes with flat tops and steep sides, as wide as 38 miles (62 kilometers), likely formed by the extrusion of highly viscous lava. “Tick” domes, odd volcanoes with radiating spurs that, from above, make them look like their blood-feeding namesake.

Mercury's surface resembles that of Earth's Moon, scarred by many impact craters resulting from collisions with meteoroids and comets. Craters and features on Mercury are named after famous deceased artists, musicians, or authors, including children's author …

Jan 9, 2025 · We argue for deployment of increasingly sophisticated in situ techniques to definitively identify biomarkers before engaging in Mars Sample Return. We focus on "following the nitrogen," using techniques such as micro capillary electrophoresis to identify and determine the chirality of primary amines

Jan 9, 2025 · Among the most amazing changes Cassini captured: the eruption of a once-every-30-years storm (one of the most powerful ever seen in the solar system), methane rainstorms at Titan and the appearance and disappearance of features such as the “magic island.”

It was here that she found an interest for geographic information systems (GIS). From her time at NASA, Fressia made connections with peers and refined her skills in space observation by diving into a career in remote sensing. For nearly three years, Fressia has worked as a 3D Image Analyst for a company that works closely with NASA and other ...
