NASA/JPL/University of Arizona Yesterday, the team that runs the HiRISE camera on the Mars Reconnaissance Orbiter released the photo shown above. It’s a new impact crater on Mars, formed sometime early this decade. The crater at the center is about 30 meters in diameter, and the material ejected during its formation extends out as far as 15 kilometers. The impact was originally spotted by the MRO’s Context Camera , a wide-field imaging system that (wait for it) provides the context—an image of the surrounding terrain—for the high-resolution images taken by HiRISE. The time window on the impact, between July 2010 and May 2012, simply represents the time between two different Context Camera photos of the same location. Once the crater was spotted, it took until November of 2013 for another pass of the region, at which point HiRISE was able to image it. Higher-resolution photos, as well as a map of the crater’s location on Mars, are available from the HiRISE website. Read on Ars Technica | Comments

Amazon has just reported its earnings for the fourth quarter of 2013 . According to The Verge , Amazon CFO Tom Szkutak mentioned that the company is considering a price increase for its Amazon Prime customers in the US. The decision hasn’t been made, but high shipping costs could prompt a price increase of between $20 and $40 a year for the service. Prime began life as a service that offered free two-day shipping on many items for a flat, $79-a-year fee. As Amazon has branched out into tablets and streaming media, perks like the Instant Video service and Kindle Owners’ Lending Library have been added to sweeten the deal. The potential price increase would be the first since Prime was introduced in the US in 2005. Amazon reported income of $239 million on sales of $25.59 billion for the fourth quarter of 2013, lower than analysts had expected. The company’s guidance for the first quarter of 2014 projects sales between $18.2 and $19.9 billion and expects income to be somewhere between a profit of $200 million and a loss of $200 million.
