Concerns over the impact that space travel has on astronauts' sight has led Canadian scientists to develop a new way to measure the mechanics of the human eye and detect ocular damage.
"We must try to protect astronauts' vision, because the negative repercussions of zero gravity provide clear cause for concern," said Santiago Costantino, a professor at the University of Montreal.
Most astronauts who spend more than a month in space develop space flight-associated neuro-ocular syndrome (SANS), which mainly affects their optic nerves.

When Do I Get to Go? A Review of "See You In Orbit? Our Dream of Spaceflight" - SpaceRef
Do you want to fly into space? Do you know someone who does? If so then this book is worth reading. "See You In Orbit? Our Dream of Spaceflight" by Alan Ladwig presents a comprehensive look by a space insider into the history of what space travel means to people.
It details how individuals, space agencies, and companies have sought to give more people a chance to visit space.
In essence personal space travel has always been a factor in what we've done in space even if it was impractical. Efforts to expand the cadre of people going into space started before we even sent people into space and have continued ever since. Eventually some of these efforts caught on. To be certain there was always internal resistance as there was resistance from the outside as to who should go into space - and why.
The Space Review: Trends in technology development in the US and USSR during the Space Race
The “Space Race” ushered in the era of space exploration with an extraordinary government-led rivalry between the United States and the Soviet Union, and their competing political ideologies. This rivalry is rightly regarded as a primary impetus to the early development of space exploration technology.
Cultural factors in particular seem to illuminate Russian interest in space exploration and hence the Soviet head start with their famous launch of the first satellite, Sputnik 1. Obviously, economic factors in their space exploration efforts also were important. Despite the brutalities of the Soviet regime, the Soviet Union (USSR) was one of the most rapidly developing economies of the 20th century (Davies 1998) [4].

Space travel can make the gut leaky: Effects of microgravity on intestinal epithelial cells --
Bacteria, fungi, and viruses can enter our gut through the food we eat. Fortunately, the epithelial cells that line our intestines serve as a robust barrier to prevent these microorganisms from invading the rest of our bodies.
A research team led by a biomedical scientist at the University of California, Riverside, has found that simulated microgravity, such as that encountered in spaceflight, disrupts the functioning of the epithelial barrier even after removal from the microgravity environment.
These Spacesuits Signal a New Era of Space Travel | FashNerd
On July 2019, there was reporting that NASA's Artemis goal of 2024 might be delayed . Not because of launch or rocket technology, but because NASA hadn't developed a new spacesuit that would meet the needs of the mission.
After much disappointment following the cancelled all-female spacewalk this summer, the spacesuit and the implications of its design limitations have been a source of public engagement and frustration. At a time when public interest in NASA could be seen as symbolic, NASA took the momentum from this news to not only rectify the situation but to reemphasize their investment in suits made for all.
Russia's status as a space power will end with the start of NASA's commercial crew | TheHill
Barring any more unforeseen developments, it looks like NASA's commercial crew will become operational by as early as the summer of 2020, according to a recent report of NASA's Inspector General . The event will, among other things, signal the beginning of the end of Russia as a space power.
SpaceX's Crewed Dragon and Boeing's Starliner were supposed to start taking astronauts to and from the International Space Station by 2017. Technical glitches and other problems have delayed the commercial crew program by three years.
Let The Expanse on Amazon Be Your New Epic Sci-Fi Obsession
With humanity spread out among the stars and dependent on technology, a caste system, and the unknown elements of outer space, it's no surprise that things get messy fast — especially once a missing rich girl enters the picture. But the mystery at the series' center gets so much bigger than you could imagine, unless you've read the James S.A. Corey novels on which the series is based. To say much more would spoil something you don't want spoiled.
