The incredible career of NASA’s Peggy Whitson, who applied to become an astronaut 10 times before she broke the American record for space travel
Posted by Michael Lance in categories: food, space travel, sustainability
She retired from NASA on Friday after blazing a trail for countless female astronauts.
NASA astronaut Peggy Whitson, the 58-year-old from Iowa farm country who spent a record-breaking 665 days in space, retired from the space agency on Friday.
“I have hit my radiation limit,” Whitson told Business Insider during a recent interview. “So not going into space with NASA anymore.”

A New Study Details Everything That Would Be Needed For An Interstellar Journey To Proxima Centauri
Posted by Genevieve Klien in categories: particle physics, space travel
Scientists have determined the minimum amount of crew members needed for a 6,300-year journey to Proxima b.
A team of French scientists have recently published a new study detailing everything that would be needed if humans were to one day make the long interstellar journey to Proxima Centauri to start a new life and civilization. The research went to great lengths to determine the correct amount of people that would ensure a successful voyage to Proxima b.
The study was conducted by particle physicist Dr. Camille Beluffi and Dr. Frederic Marin from the Astronomical Observatory of Strasbourg and marks the second study conducted on such an interstellar journey to Proxima b, as ScienceAlert reported.

Smart Robots Are the Secret to Spaceflight’s Future
Posted by Klaus Baldauf in categories: 3D printing, robotics/AI, space travel
A spacecraft, spinning in Earth’s orbit, reaches inside itself. One of its four arms pulls out a length of polymer pipe that has been 3D-printed inside the body of the machines. All four of the spacecraft’s arms are securing pieces together as it builds a new space station right there in orbit.
This surreal project, called Archinaut, is the future vision of space manufacturing company Made In Space. The company promises a future of large imaging arrays, kilometer-scale communications tools, and big space stations all built off-planet by smart robots.

Scientists Have Found Interstellar Dust on Earth That’s Older Than Our Solar System
Posted by Michael Lance in categories: particle physics, space travel
This ancient interstellar dust formed the Earth and the solar system.
Particles collected from Earth’s upper atmosphere, originally deposited by comets, are older than our Solar System, scientists say – and these fine bits of interstellar dust could teach us about how planets and stars form from the very beginning.
These cosmic particles have lived through at least 4.6 billion years and travelled across incredible distances, according to the new research into their chemical composition.

What would solar system travel be like with scaled Mach effect propellantless propulsion?
Posted by Klaus Baldauf in categories: nuclear energy, space travel
James Woodward and the Space Studies Institute has a Phase 2 NASA Innovative Advanced funded study. They are looking at the implementation of an innovative thrust producing technology for use in NASA missions involving in space main propulsion.
Dr. Heidi Fearn explained in a video made in 2017 how just scaling the power and size of the Mach effect propulsion causes problems. (heat, arcing and other problems). They currently believe they can scale the device to one newton of propulsion and then create large arrays of the devices for more thrust. The constant thrust could last for years or decades by using a nuclear power source.
For Mach effect propellantless propulsion it will be better to go to an array of smaller devices.
