Microgravity in space perturbs human physiology and is detrimental for astronaut health, a fact first realized during early Apollo missions when astronauts experienced inner ear disturbances, heart arrhythmia, low blood pressure, dehydration, and loss of calcium from their bones after their missions.
Study: Why Space Travel Weakens Human Immune Cells
Microgravity in space perturbs human physiology and is detrimental for astronaut health, a fact first realized during early Apollo missions when astronauts experienced inner ear disturbances, heart arrhythmia, low blood pressure, dehydration, and loss of calcium from their bones after their missions.
In the last study led by one of the first women astronauts, Millie Hughes-Fulford, researchers at UCSF and Stanford University now have shown that the weakening of an astronaut's immune system during space travel is likely due in part to abnormal activation of immune cells called T regulator cells (Tregs).
Mapping Gene Activity In Tissues Just Got Easier And Why It Matters For Space Travel
Although Visium is already being used by many researchers, 10x discovered an opportunity to make it even more useful for scientists. In general, tissue samples that come from a biopsy are immediately placed in formalin (formaldehyde) or another solution to preserve them. However, studying gene activity in preserved tissues is difficult, so 10x found a way to change this.
"One of the first things that happens to tissues is putting them in a fixative," says Ben Hindson, co-founder and CSO of 10x. "The previous limitation was that a lot of the tissues being used by researchers were preserved or frozen, so you get these formalin-fixed and paraffin-embedded blocks. This destroys most of the RNA, which is the good stuff you are trying to look for in the sample."
Look at the ambitious plans for Voyager Station, a hotel in outer space
Orbital Assembly Corporation, billed as the world’s first large-scale space construction company and run by former pilot John Blincow, aims to open Voyager Station in 2027. The company recently opened a new production facility in Fontana, Calif.
“We’re trying to make the public realize that this golden age of space travel is just around the corner,” Blincow told CNN . “It’s coming. It’s coming fast.”
How Risky Is It to Send Jeff Bezos to the Edge of Space? | WIRED
Blue Origin founder Jeff Bezos and Virgin Galactic founder Richard Branson have been working for the past 20 years to get their companies' rockets built and launched. Now both are preparing to suit up and ride their own spacecraft. Bezos announced on Monday that he'll blast off July 20 on Blue Origin's New Shepard rocket, riding to the limit of Earth's atmosphere. Meanwhile, Branson is expected to fly this summer on the Virgin Galactic VSS Unity rocket plane to the same zone.

Picture yourself suspended in space, staring down at the blue marble you call home. This could soon be a reality, depending on your tax bracket, height and weight. Companies like Virgin, SpaceX, and Blue Origins are pioneering the commercial space travel industry in America. A ticket on a civilian spacecraft could cost between $250,000 to $55 million, depending on how intergalactic you're trying to get.
Two Cal Poly seniors develop rovers with outer space in mind
To study new planets for space travel and colonization -- that's the goal of two Cal Poly graduating seniors.
The students even named the rovers. The white one is Herbie, and the black one is The Exoskeleton. Herbie is equipped with a camera that can track and follow a person's movements, and The Exoskeleton has better movement abilities, the students say.
"I love that I can actually make it do things. I have very good control over it," Ozawa said. "If I don't like a behavior due to the command, I can change that."
