After spaceflight record, NASA looks to protect astronauts on even longer trips

NASA astronaut Frank Rubio floats by the International Space Station’s “window to the world.” Yesterday, he returned from the longest single spaceflight by a U.S. astronaut on record - over one year. Exploring deep space will require even longer missions.

NASA

Inside the Atlantis Space Shuttle, astronauts waited for liftoff. At T-minus six seconds, the main engines ignited, rattling the capsule “like a skyscraper in an earthquake,” according to astronaut Tom Jones, describing the 1988 launch in Air & Space Magazine. Liftoff came with what felt like “a massive kick in the back,” he recalled, along with more shaking. As the rocket accelerated to three times the force of gravity on Earth, “It felt as if two of my friends were standing on my chest and wouldn’t get off!” Finally, at 25 times the speed of sound, Atlantis reached orbit. The main engines cut off, and the astronauts were weightless.

Since 1961, NASA has sent hundreds of astronauts into space while working to making their voyages safer and smoother. Yet, challenges remain. Weightlessness may look amusing when watched from Earth, but it has myriad effects on cognition, movement and other functions. When missions to space stretch to six months or longer, microgravity can harm astronauts’ health and performance, making it more difficult to operate their spacecraft.

A newly discovered brain cell may lead to better treatments for cognitive disorders

Swiss researchers have found a type of brain cell that appears to be a hybrid of the two other main types — and it could lead to new treatments for brain disorders.

Swiss researchers have discovered a third type of brain cell that appears to be a hybrid of the two other primary types — and it could lead to new treatments for many brain disorders.

The challenge: Most of the cells in the brain are either neurons or glial cells. While neurons use electrical and chemical signals to send messages to one another across small gaps called synapses, glial cells exist to support and protect neurons.

Astrocytes are a type of glial cell found near synapses. This close proximity to the place where brain signals are sent and received has led researchers to suspect that astrocytes might play an active role in the transmission of information inside the brain — a.k.a. “neurotransmission” — but no one has been able to prove the theory.
