Geologists study anomalies in the geophysical and chemical properties of the earth to look for minerals according to their properties. There is a need to identify and exploit the mineral strength of a nation to run certain parts of its economy. From precious metals to natural gas and petroleum,...

While the rovers aren't exactly punching a clock every morning, they do send images, along with instrument and status data, back to their Earth bosses. Extrapolating from the data, the scientists send commands to the rover during the three-hour window of direct communication with the high-gain...
One of the problems that make it difficult to solve the mystery of the origin of life is determining how life emerged in chemically complex messy environments on primitive Earth. In this article, the “chemically complex messy environments” that are focused on are a mixed state of various orga...
In terms of pricing, the proportion of green consumers in the market and their preference for brown products (within a certain range) do not affect the retailer’s pricing strategy in the agent selling model. However, in the direct selling model, more green consumers or a smaller difference ...

land's surface. Any resources found beneath that surface would be owned by the nation itself and controlled by its government. For example, in the United Kingdom, mineral rights for oil, gas, coal, gold, and silver are owned by the state. Minerals for other commodities are privately held....
But why are scientists so interested in going to this one particular location? How do you guess where life might have evolved millions or billions of years ago, on an alien planet? What makes Jezero so special? We spoke to an expert in Mars geology, Katie Stack Morgan of NASA's...
Globally, around 190 impact craters (or their eroded remnants) have beendiscovered on Earth– a lot fewer than scientists predict should have formed over all of Earth's history. This is because the Earth's surface is quite a dynamic place, and processes of erosion and plate tectonics act to...
NASA’s New Earth Space Mission Initially, NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) mission was intended solely to map the distribution of key minerals in the planet’s dust deserts. However, EMIT has demonstrated that it can also detect the presence of methane. In data...
