Forming rings of X-ray light that expand with time, creating a shooting target effect
Space news (astrophysics: binary star systems; black hole/sun-like star systems) – 8,000 light-years away toward the constellation Cygnus, next to flaring 10 solar mass black hole –
It all started just before 2:32 p.m. on June 15, 2015, when NASA’s Swift X-ray Burst Alert Satellite detected a rising wave of high-speed, extremely-energetic X-rays emanating from the direction of the constellation Cygnus. Additional detections of the same flare ten minutes later by a Japanese experiment on the International Space Station called the Monitor of All-sky X-ray Image (MAXI) and other detectors. Allowed astronomers to determine the outburst detected originated 8,000 light-years away in low-mass X-ray binary V404 Cygni, where previous data indicated a stellar-mass black hole and sun-like star orbited each other. A black hole and sun-like star binary system that up to this point had been sleeping since its last outburst in 1989.
Fifteen days later on June 30, a team of scientists from around the world led by Andrew Beardmore of the University of Leicester in the United Kingdom investigated V404 Cygni a little closer using NASA’s Swift X-ray Burst Alert Satellite. Images taken (above) revealed a series of concentric rings of X-ray light centered on a 10 solar mass black hole (dot at the center of image).
Astronomers believe the x-ray rings are the result of echoing x-ray light from a large flare on June 26, 2016, at 1:40 p.m. EDT. The flare emitted x-rays in all directions. Multiple dust layers at around 4,000 and 1,000 light-years from V404 Cygni reflected some of these x-rays towards Earth. This reflected light travels a greater distance and reaches us slightly later than light traveling a straighter path. The small time difference produced an x-ray echo, formed x-ray rings expanding in spacetime.
“The flexible planning of Swift observations has given us the best dust-scattered X-ray ring images ever seen,” Beardmore said. “With these observations, we can make a detailed study of the normally invisible interstellar dust in the direction of this black hole.”
The team is currently watching V404 Cygni, waiting for its next outburst, and preparing Swift to collect additional data to determine exactly what’s going on here. They hope to hit the bulls eye in human understanding of the collection on x-ray sources detected across the cosmos. Regular monitoring of this binary system using a suite of telescopes and instruments could give us clues to how a stellar-mass black hole and sun-like star end up orbiting each other. About the origin and formation of the unusual types of binary systems detected during the human journey to the beginning of space and time.
Gadgets, ratchets, and things that go bump in the dark on demand
Space news (space technology: Future Engineers Space Tool Challenge; The Multipurpose Precision Maintenance Tool) – The International Space Station, June 15, 2014 –
Travelers adventuring in distant, unknown lands can’t carry a tool and replacement for every job along the way. They need a multipurpose tool designed to do a number of important tasks, ready to go to work at a moments notice. For astronauts traveling, living and working in space, University of Alabama in Huntsville sophomore engineering student Robert Hillan has designed The Multipurpose Precision Maintenance Tool as part of the Future Engineers Space Tool Challenge. A single tool capable of helping astronauts complete a number of jobs, including tightening and loosening bolts and nuts of various sizes, and stripping wires. The best part’s the Multipurpose Precision Maintenance Tool recently debuted on the International Space Station.
“Our challenges invite students to invent objects for astronauts, which can be both inspiring and incredibly tough,” said Deanne Bell, founder and director of the Future Engineers challenges. “Students must have the creativity to innovate for the unique environment of space, but also the practical, hands-on knowledge to make something functional and useful. It’s a delicate balance, but this combination of creativity, analytical skills, and fluency in current technology is at the heart of engineering education.”
As part of his prize after winning the Future Engineers Space Tool Challenge in January of 2015, Robert Hillan watched from the Payload Operations Integration Center of NASA’s Marshall Space Flight Center in Huntsville, Alabama as his tool came off the 3-D printer on the International Space Station. Robert smiled as NASA astronaut Jeff Williams showed the completed tool coming off the Additive Manufacturing Facility on board.

“I am extremely grateful that I was given the opportunity to design something for fabrication on the space station,”Hillan said. “I have always had a passion for space exploration, and space travel in general. I designed the tool to adapt to different situations, and as a result, I hope to see variants of the tool being used in the future, hopefully when it can be created using stronger materials.”

Robert also got to spend a few minutes chatting with astronauts living and working on the International Space Station. NASA astronaut Tim Kopra, stationed aboard at the time commented on Hillan’s tool, “When you have a problem, it will drive specific requirements and solutions. 3-D printing allows you to do a quick design to meet those requirements. That’s the beauty of this tool and this technology. You can produce something you hadn’t anticipated and do it on short notice.”

“You have a great future ahead of you.”
What does our young, intrepid inventor plan in the future?
What’s next for our young inventor?
“When I won the competition, I started seeing problems I face as new opportunities to create and learn,” Hillan said. “Since then I have tried to seize every opportunity that presents itself. I love finding solutions to problems, and I want to apply that mentality as I pursue my engineering degree and someday launch my own company.”
We see red horizons ahead for this young man. A steady light that goes bravely forward into the future. We expect to hear about him doing big things in the future. No matter the path he chooses.

Astronauts in orbit need to be able to monitor their body mass to stay healthy and strong
Space news (astronaut health: protecting astronauts in space; SLAMMD) – the International Space Station –
Traveling in an orbiting spacecraft is hazardous to human health and can lead to bone and muscle mass loss in astronauts during extended missions on the International Space Station. The loss of a significant amount of body mass can have severe consequences all astronauts need to take into serious consider during long stays in space.
The concept of the difference between a body’s mass and weight is something NASA and all astronauts in orbiting spacecraft need to take into serious consideration. Weight is the downward force exerted by a mass as a result of gravity. Mass is the amount of matter contained within an object. On a regular schedule, astronauts in the International Space Station will conduct a body mass measurement, using a Space Linear Mass Measurement Device (SLAMMD). This is a device operating on the principles of Newton’s Second Law of Motion (F = ma) that measures an astronauts’ mass while in orbit to an accuracy of 0.5 pounds.
The SLAMMD was initially installed during Expedition 11 and has since this time been used consistently by astronauts on the International Space Station to measure their body mass. Essentially, it works using two springs located in a drawer, which is attached to the astronaut being measured. The SLAMMD is designed to always apply a constant force no matter how far the springs are stretched. It measures the average acceleration of an astronauts’ mass, which is used along with the equation F = ma to calculate the mass of the astronaut.
The average acceleration of an astronauts’ mass is precisely measured by an optical device which detects the trajectory of the SLAMMD guide arm. A microcontroller collects the displacement versus time data and provides the precise timing required.
