How does the human body react to being in space? A study of twin astronauts Scott and Mark Kelly suggest long duration spaceflight alters genes, body functions, and mental well-being in astronauts.

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 space.

What 600 days in space does to living cells The BIOlogy and Mars EXperiment (BIOMEX) project used Chroococcidiopsis sp., a rock-inhabiting microorganism found in sandstone from the Negev Desert, to study how life might survive on the Moon. Find out why.

Another study testing the limits of life in space, this time on the moon! #moon #lifeinspace #humanspaceflight #NASA #cyanobacteria #astrobiology

Is humanity ready to live in space? To live in space, we will need inter-generational cooperation to pull it off, and perhaps a sense of altruism for the future. We may be up to the technical challenge, but what about the sociopolitical challenges?

This article explores incentives for projects spanning millennia, and determines which of those incentives would provide the most successful approach.

Astronauts suffer permanent brain changes after long flights Long-duration spaceflight was associated with increased brain sizes. These effects lasted up to 1 year into recovery, suggesting permanent alteration.

Space flight is known to cause blurry vision in astronauts. Swelling of the brain tissue may be the reason, according to a study using MRIs.

Bread yeast can help humans explore space! Studying the effects of radiation on yeast cells can help us understand how astronauts’ bodies may be affected during long term space travel. This paper describes an experiment that will be conducted on board the satellite BioSentinel.

How do we find the effects of extreme #space radiation on human health? Answer lies with yeast in your bread! @NASA scientists are launching #BioSentinel later this year. #Astrobiology By @strayologist

Dried plums may protect astronaut’s bones from radiation damage In a mouse study, researchers from NASA Ames Research Center have demonstrated that compounds in plums may protect bones from radiation damage.

Dried plums outperformed some medications in a bone health study (in mice) at NASA Ames.

NASA is sending yeast into deep space NASA will generate invaluable data on yeast’s response to deep space radiation by launching the BioSentinel satellite in 2021. Here’s how they’ll do it.

NASA will generate invaluable data on yeast’s response to deep space radiation by launching the BioSentinel satellite in 2021. Here’s how they’ll do it.  It’s an exciting time to be interested in space. We’re in an era of scientific discovery READ MORE

Growing plants on the surface of the Moon and Mars Researchers tested the growth of 10 different common food crops in simulated regolith, a rocky substance lacking organic material found on the surface of Mars and the Moon.

The reality of being able to live and settle on Martian or lunar bases can seem like it is getting close. To do this, we need to be able to grow our own food there. This is a category of READ MORE
