First SpaceX commercial crew test flight could slip to 2019
Posted by Genevieve Klien in category: space travel
BREMEN, Germany — A SpaceX executive said Oct. 3 that the company’s first commercial crew test flight could be delayed until early 2019 because of paperwork issues.
In a speech at the 69th International Astronautical Congress here, Hans Koenigsmann, vice president of build and flight reliability for SpaceX, said launching an uncrewed test flight before the end of the year will be a “close call” even though the hardware itself should be ready.
“We’re working hard to get this done this year,” he said. “The hardware might be ready, but we might still have to do some paperwork on the certification side of it. It’s going to be a close call whether we fly this year or not.”

Deep Space Exploration Could Permanently Damage Human GI Tracts
Posted by Shailesh Prasad in categories: biotech/medical, space travel
Humans aren’t built for deep space exploration. We’ve evolved to live here on Earth with an atmosphere, gravity, and a vitally important magnetic field that deflects high-energy cosmic radiation. It will take all our technological prowess to expand on to other worlds, and it won’t simply be a matter of physically getting there. We also need to preserve delicate human biology. A new study from Georgetown University and NASA suggests it may be much harder than we thought to ensure astronauts maintain healthy gastrointestinal (GI) tract tissue in space.
While doctors expect long-term exposure to high-energy radiation will have myriad effects, it’s difficult to study them in a lab on Earth. The effects of the GI tract are easier to assess because the cells lining this body system are replaced every few days. New cells migrate upward from a structure called a “crypt” to take their places lining the gut. Any disturbance of this mechanism can lead to dysfunction.
The study assessed mice under exposure to different radiation conditions as an analog for humans. They’re much smaller, so they can’t handle as much radiation has a human. However, their GI tracts respond much like ours would from exposure to high-energy particles. The researchers used the NASA Space Radiation Laboratory (NSRL) in Brookhaven National Laboratory to bombard the mice with either simulated galactic cosmic radiation (sometimes called cosmic rays), gamma rays, or no radiation (control group).

It’s Official: NASA Just Announced a Bold 3-Part Plan to Send Humans to The Moon And Mars
Posted by Shailesh Prasad in categories: policy, space, space travel
NASA’s got a whole new plan. It wants boots on the Moon in 10 years and on Mars in 20. Give or take.
On Wednesday, the space agency announced its detailed National Space Exploration Plan to achieve the President’s lofty goals set out in his December 2017 Space Policy Directive-1.
Those bold plans include: planning a new Moon landing, long-term human deployment on and around the Moon, reassertion of America’s leadership in space, strengthening private space companies, and figure out how to get American astronauts to the surface of Mars.

5 Sci-Fi Books Biotech Geeks Should Read Right Now
Posted by Mike Ruban in categories: biotech/medical, robotics/AI, space travel, time travel
From space colonization to resurrection of dinosaurs to machine intelligence, the most awe-inspiring visions of humanity’s future are typically born from science fiction.
But among an abundance of time travel, superheroes, space adventures, and so forth, biotech remains underrepresented in the genre.
This selection highlights some outstanding works (new and not so new) to fill the sci-fi gap for biotech aficionados.

Jeff Bezos plans to build and launch a ‘large lunar lander’ in his quest to colonize space
Posted by Genevieve Klien in categories: economics, robotics/AI, space travel
Jeff Bezos, the richest person on Earth, is designing a spacecraft to land on the moon with his rocket company, Blue Origin. The “Blue Moon” robot is expected to deliver several metric tons of supplies to the surface, though Blue Origin is working with others to establish a larger lunar economy.

Set to give a keynote speech on October 3rd at 2018’s International Astronautical Congress (IAC), Hans Koenigsmann – SpaceX Vice President of Build and Flight Reliability – attended an impromptu talk one day prior, titled “From the University of Bremen to SpaceX”.
Speaking before a small audience, the University of Bremen graduate and fourth employee to join SpaceX discussed his opinions of Falcon Heavy, BFR, and more, frankly relating how SpaceX intentionally chose to build Falcon Heavy on its own, going so far as to turn down funding reportedly offered by one or more US government agencies.

Traveling to Mars Could Cause Life-Threatening Damage to Astronauts’ Guts, Says Study
Posted by Michael Lance in categories: biotech/medical, health, space travel
Spend months in space, and you could develop cancer.
To study the effects of deep space radiation exposure on astronaut health, researchers exposed mice to comparable levels of radiation. It hurt their guts.
