Humans in Space!

What happens when astronaut teams don’t get along?

Professor Contractor Noshir knows how to help you get along better with your coworkers. He studies the interpersonal dynamics of crews in extreme environments,…


Microbes from extreme environments help us study space

Space is a hostile place. It has numerous stressors which make it seem impossible for Earth-like life to thrive there. Some of these stresses include harmful…


Building a better spacesuit for a trip to Mars

An intra-vehicular space suit and a storm shelter will help protect astronauts from radiation during a trip to Mars. Infusing the suit material with graphene…


How does the human body react to being in space?

Is going to space safe for human health? Two astronauts, who were twins, volunteered for a research study to look at how the body changes when it goes into…

All life on Earth survives because of the sun. Plants use a process called photosynthesis to transfer energy from the Sun’s rays into the sugars that build their stems and leaves. Animals either eat the plants directly, or eat other animals that have eaten plants. Countless other organisms, like bacteria, algae, and…

So far, we cannot be sure that this question has been properly answered. Even so, NASA has proposed that life be taken as a self-sustained chemical system capable of undergoing Darwinian evolution. If we have a mind for science, we might then ask – is this consistent with basic principles? The life chemistry we…

Plumes seen reaching high above the surface of Mars are causing a stir among scientists studying the atmosphere on the Red Planet On two separate occasions in March and April 2012, amateur astronomers reported definite plume-like features developing on the planet. The plumes were seen rising to altitudes of over 250 km…

Human-caused climate change, ocean acidification and species extinctions may eventually threaten the collapse of civilization, according to some scientists, while other people argue that for political or economic reasons we should allow industrial development to continue without restrictions. In a new paper, two…

Using an experiment carried into space on a NASA suborbital rocket, astronomers at Caltech and their colleagues have detected a diffuse cosmic glow that appears to represent more light than that produced by known galaxies in the universe. The researchers, including Caltech Professor of Physics Jamie Bock and Caltech…
