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.
The representation of politicians has always been a tricky issue, but recently we’ve seen social media become more and more important as an influence on public opinion, especially relating to the US presidential campaign and the Labour leadership row here in the UK.
Snapchat just dropped some huge news - rebranding to Snap Inc. and revealing their first piece of hardware named Spectacles. I'm struggling to understand the point of some sunglasses with a video camera attached to them, but surely it can't be just because I'm not a millennial...
For years, developed countries have accepted and almost forgotten about the privilege of Internet access – while 4 billion people across developing nations live without it.
Well, here we are... The fifth anniversary of New Rising Media. It's been a journey quite like that of a TV sitcom relationship - falling in and out of love with this place.
There have been highs and lows, as the landscape of blogging has changed. And just like any birthday celebration, I want to reminisce in the history of things around here.
Unless you've been living under a rock, Apple launched their AirPods... Turns out there's a lot wrong with them!
While a robot may never be capable of feeling emotion, artist Erica Scourti’s bot “Empathy Deck” has the potential to pretend well enough to offer comforting help.
Ignore what the more easily influenced friends are sharing on Facebook - NASA did not just change your Zodiac sign. This was all just big misunderstanding, based on a children’s education web page put out by the agency.
We all have a laugh and a joke about being so addicted to Pokemon Go that you play while driving - but unfortunately that’s not a joke to thousands of people…
YouTube Gaming channels are rapidly becoming a major part of online entertainment. Whether it be Let’s Players, Review and Analysis, News Channels, or any number of variations, more and more people are making their living either playing or discussing games – and attracting legions of fans while they do so. However, one thing this rapidly-growing medium has so far lacked is a concrete set of laws and legislation behind it, and that might be set to change, thanks to an incident in Essex.
Researchers believe they’ve developed a new way to power wearable technology - harvesting body heat for electricity.
