The Martian rover Opportunity has become famous for its amazing longevity, but it is not the only one; orbiting spacecraft also usually enjoy long lifespans, and today the Mars Reconnaissance Orbiter is celebrating its 10th year exploring Mars […]

Welcome to Bagnold: Curiosity Rover Reaches Massive Dark Sand Dunes Near Mount Sharp

View overlooking part of High Dune, which is covered in smaller sand ripples. The image is white-balanced, to show how the scene would look under more Earth-like conditions. Image Credit: NASA/JPL-Caltech

Since landing in 2012, the Curiosity rover has seen a lot of varied terrain within Gale crater, including ancient riverbed gravel, sandstone and […]

The Saline Slopes of Mars: NASA Confirms Evidence for Flowing Liquid Water

False-color image of RSL on slopes in Hale crater. The blue color is thought not to be related to their formation, but instead are from the presence of the mineral pyroxene. The image is produced by draping an orthorectified (Infrared-Red-Blue/Green(IRB)) false color image (ESP_030570_1440) on a Digital Terrain Model (DTM) of the same site […]

Testing Panspermia: Searching for 'Bubbles of Life' in the Galaxy

Does life spread through the galaxy like an infectious disease, with “bubbles” of inhabited planets? Image Credit: Harvard-Smithsonian CfA

We still don’t know if there is life elsewhere in the universe, but scientists are working on techniques to better understand how it may have originated anyway, in the event that such alien biology is […]

Curiosity Finds First Evidence For Possible 'Continental Crust' on Mars

For several decades, Mars has been a busy place, with orbiters, landers, and rovers providing unprecedented views of the Red Planet. Another exciting possibility which has yet to be realized is an airplane, which could soar through […]

Methane Discovered in Martian Meteorites: A Clue to Possible Life?

Methane has been discovered in some meteorites originating from Mars. Could it be a clue to life? Image Credit: Michael Helfenbein

The puzzle of methane on Mars has taken an interesting new twist: For the first time, the gas has been detected within Martian meteorites. The finding adds another layer to the ongoing controversy […]

Exploring an Alien Sea: NASA Designs Submarine to Send to Titan

Who wouldn’t want to go explore an alien sea? It seems that NASA would certainly like to, and the agency has unveiled a new […]

Cool New Technology Will Allow Scientists to Work Virtually on Mars in 3-D

A screen view from OnSight, showing how scientists can meet together in a virtual 3-D simulation on the Martian surface. Such technology will allow scientists to better study features of interest and plan rover or lander activities. Image Credit: NASA/JPL-Caltech

The rover and lander missions on Mars have been cool enough with their high-tech […]
