NASA has released an amazingly detailed gravity map of Mars, which shows forces around the red planet and huge amounts of physical properties. This was created using range tracking and Doppler data, collected from three different spacecraft orbiting Mars for over a decade: the Mars Global Surveyor (MGS), Mars Odyssey (ODY), and the Mars Reconnaissance Orbiter (MRO).
Like most planets, Mars has a bumpy surface that affects levels of gravitational pull across all of it. NASA's gravity map plots these fluctuations, to help future spacecraft navigate the fluctuations of flying over mountains and canyons. Creating this map required two years of data analysis and modelling to confirm each painstaking detail.
With both the high and low points in the gravitational field identified around the planet, this allows us to gather huge amounts of detail about the physical features of Mars, such as crustal thickness, seasonal variations, levels of ice at the poles, etc.
“With this new map, we’ve been able to see gravity anomalies as small as about 100 kilometers (about 62 miles) across, and we’ve determined the crustal thickness of Mars with a resolution of around 120 kilometers (almost 75 miles),” said MIT’s Antonio Genova commented. “The better resolution of the new map helps interpret how the crust of the planet changed over Mars’ history in many regions.” The research team was able to estimate the amount of carbon dioxide that freezes out of the atmosphere during a Martian winter. They also were able to observe the changes in the north and south poles that occurred with the changing of the Martian seasons.
Kickstarter is both a blessing and a curse – for every amazing innovation we get, we get a few stupidly pointless gadgets just like these five pieces of tat.
Google’s DeepMind AI has taken a break from painting masterpieces and besting board game champions to learn a spot of Parkour – using reinforcement learning in encouraging the AI to successfully navigate a course of jumps and crawls.
Astronomy photography is difficult enough, but imagine doing so using a Nintendo Game Boy Camera! Well, this guy has managed to do so and the results are better than you imagine…
With the success of Crash Bandicoot N. Sane Trilogy, here are 6 more classic platformers that deserve to be remastered.
You use Facebook, right? No doubt you’ve been warned by your more socially naïve friends not to accept a request from Jayden K Smith. Well, unsurprisingly, this is a hoax and your friends are idiots for sharing it.

Raging at how difficult Crash Bandicoot N. Sane Trilogy is? Turns out you’re not the only one, and there’s a legit reason why this remaster is way harder...
Mobile phone battery life sucks. Just look at the surge in battery pack sales. Well, the University of Washington have noticed this and proposed a new alternative - getting rid of batteries altogether.
