Curiosity Rover: Looking Back on the Two Years of Wear and Tear Inflicted By Mars
It’s insanely hard to believe that Curiosity has been traversing Mars for a full two years now, but, as these images show, time has certainly taken a toll on it. See before and after images of the damage: http://bit.ly/1pP0GpQ
The law of conservation of mass, or principle of mass conservation, states that for any system closed to all transfers of matter and energy (both of which have mass), the mass of the system must remain constant over time, as system mass cannot change quantity if it is not added or removed. Hence, the quantity of mass is “conserved” over time. The law implies that mass can neither be created nor destroyed, although it may be rearranged in space, or the entities associated with it may be changed in form, as for example when light or physical work is transformed into particles that contribute the same mass to the system as the light or work had contributed. The law implies (requires) that during any chemical reaction, nuclear reaction, or radioactive decay in an isolated system, the total mass of the reactants or starting materials must be equal to the mass of the products.
At SciNote, we believe that science shouldn’t just be reading about the ideas of people with PhDs and Nobel Prizes. We believe that science is an active process of asking questions and finding answers.
That’s why we, at SciNote, want to hear from you. We want to ponder the interesting questions you pose and get excited with you over the cool science you see in your world.
SciNote will feature the best of the Tumblr science community, and we will compile and publish the top posts from every year in the form of a magazine available both digitally and in print. Think of SciNote magazine as the Tumblr science magazine.
We hope to celebrate our launch by featuring some of the coolest science from around Tumblr. So before we launch SciNote, we would like to collect 25 science posts and/or questions from you, including:
the most interesting science news you have come across
questions you’ve always wanted to ask
fascinating facts that you’ve learned
pictures of nature and/or science that you’ve taken
cool research that you’ve participated in
any other science-related thing you’d like to tell us!
