HOUSTON (NASA PR) — For over 50 years, NASA’s Human Research Program (HRP) has studied what happens to the human body in space. Researchers are using what they learn to design procedures, devices, and strategies to keep astronauts safe and healthy throughout their missions.

MOFFETT FIELD, Calif. — Living in space isn’t easy. There are notable impacts on the biology of living things in the harsh environment of space. A team of scientists has now identified a possible underlying driver of these impacts: the powerhouse of the cell, called mitochondria, experiences changes in activity during spaceflight.

Former Astronaut Mark Kelly Elected to U.S. Senate

by Douglas Messier
Managing Editor

Former NASA astronaut Mark Kelly has won election to the U.S. Senate from the state of Arizona, joining a small group of space explorers subsequently elected to serve in Congress.

The Associated Press reports that with 83 percent of the votes in, Kelly has 1,444,645 votes (52.6 percent) while Republican Sen. Martha McSally trails with 1,300,119 votes (47.4 percent). Kelly has declared victory and McSally has conceded the race.

Kelly, a Democrat who flew aboard the space shuttle four times, and McSally competed in a special election to fill the last two years of the late Republican Sen. John McCain’s six year term.

NASA’s Landmark Twins Study Reveals Resilience of Human Body in Space

WASHINGTON (NASA PR) — Results from NASA’s landmark Twins Study, which took place from 2015-2016, were published Thursday in Science. The integrated paper — encompassing work from 10 research teams — reveals some interesting, surprising and reassuring data about how one human body adapted to — and recovered from — the extreme environment of space.

The Twins Study provides the first integrated biomolecular view into how the human body responds to the spaceflight environment, and serves as a genomic stepping stone to better understand how to maintain crew health during human expeditions to the Moon and Mars.

NASA Twins Study Confirms Preliminary Findings

Editor’s note: NASA issued the following statement updating this article on March 15, 2018:

Mark and Scott Kelly are still identical twins; Scott’s DNA did not fundamentally change. What researchers did observe are changes in gene expression, which is how your body reacts to your environment. This likely is within the range for humans under stress, such as mountain climbing or SCUBA diving.

Review: Scott Kelly’s Memoir About a Year in Orbit

Endurance: A Year in Space, A Lifetime of Discovery
by Scott Kelly with Margaret Lazarus Dean
Alfred A. Knoff
2017
369 pages

Scott Kelly was failing out of college when he spotted a book at the campus store that would utterly change his life: The Right Stuff, Tom Wolfe’s classic tale of Cold War-era test pilots and the Mercury astronauts.

As he read Wolfe’s prose, Kelly realized that flying jets had the same type of adrenaline rush he felt working as an EMT, which had been the only thing he had excelled at thus far. He decided he would pursue a career as an U.S. Navy aviator.

Decades later, he would call Wolfe in the midst of a year-long stay aboard the International Space Station (ISS) to thank him and ask for advice about how to write a book of his own.

Endurance is the result. The memoir doesn’t live up to Wolfe’s stylistic brilliance, but what the book lacks in style it more than makes up for in inspiration.

HOUSTON (NASA PR) — It begins with one instrument. Then another joins in. Before you know it a grand symphony is playing before your eyes. NASA Twins Study researchers are eager to integrate their results and create a symphony of science.

Preliminary findings were discussed during the Human Research Program Investigators’ Workshop in January, and now enthusiasm abounds as the integration process begins. The investigators are a unique group of researchers with different expertise associated with genetic and physiological areas of study. (more…)

“2014 will be a fun ride. We welcome you to get onboard, strap in and hold on!”

Stu Witt

CEO & General Manager
Mojave Air and Space Port
Jan. 9, 2014

Stu Witt had a lot of reasons to be optimistic as 2014 began. The Mojave spaceport was on a roll. On Jan. 10, Scaled Composites conducted the third powered flight of SpaceShipTwo in less than 9 months. XCOR was making steady progress on the Lynx and a new hydrogen engine for ULA, Stratolaunch was busy building the world’s largest aircraft, and other tenants such as Masten and Firestar had successes over the past year.
