The concentration of oxygen rises in the Martian spring, peaks in summer declines in autumn and sits at a low level in winter. This fits the idea of life burgeoning in the spring, thriving in summer, slowing down in autumn in preparation for lying dormant in the winter. It all fits the ...
his group’s system could produce nearly 60 grams of oxygen per hour. The researchers say this level of production could remove the need for future astronauts to transport oxygen from Earth. "The robot can work continuously for years," Jiang said. ...
Parallel testing will continue in a laboratory on Earth to simulate conditions on the red planet as the project looks to expand the machine to about a cubic metre in size. Despite the challenges, Hecht hailed the test results as ...

Sea-level stability over geological time owing to limited deep subduction of hydrated mantle Article 14 April 2022 Main The concept of deep magma oceans covering parts of the Earth during its earliest history is well established. Evidence that supports the development of such oceans includes energy...
These weights were carefully adjusted so that the divers could experience underwater the gravity of the Moon and of Mars as they walked on the treadmill. Newman concluded that walking on Mars will probably be easier than walking on the Moon. The Moon has less gravity than Mars does, so at...
the average % change from 1 g for each g-level was applied to the mean 1 g value; hence 1 g data points and g-levels where only a single data point was collected are not shown with error bars. Trends shown are calculated based on centrifuge data only and have an R2value of...
