SAN FRANCISCO — Astronauts often wrestle with blurry vision during spaceflight and this problem is jeopardizing longer missions to Mars.
Half of the astronauts on the International Space Station have already experienced reduced visual acuity, most noticeable at near distances. And specialists here on Earth have observed combinations of choroidal folds, disc edema, and cotton wool spots in their eyes.
On the space station, the astronauts test themselves or one another, pulling each diagnostic instrument from a tangle of wires and equipment that covers every surface inside the station.

New NASA study finds long-haul danger for astronauts: Blood flow in reverse
Spaceflight can halt and even reverse blood flow in astronauts' upper bodies, a NASA report said Wednesday, a startling discovery that has important implications for future trips to Mars and other long-duration missions.
Now, in the unexpected discovery, researchers have found that spending time in space can affect how blood flows through a major blood vessel in the upper body, causing it to halt or even flow backwards — a health risk that was unknown until now.

Elon Musk's reusable rockets may fuel an investment boom in space travel
S pace travel is extraordinarily expensive but that is about to change – and the impact could be profound.
Imagine you are flying from London to New York. After safely touching down at JFK, you disembark to head for passport control and collect your bags.
As you do so, a tow-truck lumbers across the tarmac, drags away the aircraft and pushes it into the sea.

Ever since Soviet scientists successfully fired Sputnik into low Earth orbit in 1957, the industry has struggled but failed to develop launch vehicles which can be safely and reliably reused like regular aircraft.

In 1969 the United States became the first nation to put a man on the moon and return him safely to earth under the Apollo 11 mission. The following six missions all returned to the moon, save the ill-fated Apollo 13.
Since Apollo 17 left the moon in 1972, mankind has not returned, instead setting its sights on missions to low Earth orbit.
For NASA, there is a new directive: return to the moon and travel to Mars, reaching farther than humans have ever traveled.

The story behind the first batch of cookies in space and the first zero-gravity oven | News |
And understandably so. For the last year and a half, husband and wife duo Ian and Jordana Fichtenbaum, founders of Zero G Kitchen , have been developing the first zero-gravity oven that could revolutionize space food and bring a taste of home to astronauts who dearly miss it. Last week, the oven arrived at the space station. No date has yet been announced for it to be tested.
The Fichtenbaums' mission is both simple and highly technical: "We want to build a kitchen in space, one piece at a time, and partner with companies, educators and researchers all along the way," said Ian Fichtenbaum.
