First steps: Robonaut from the ISS gets new legs for Easter

Robonaut R2, the first robotic humanoid working on the International Space Station, has finally received its legs. The ‘present’ to R2, delivered by a SpaceX rocket, marks one more milestone in space humanoid robotics.

Robonaut, currently only a torso, head and arms, is attached to a support post and has been operating on the ISS for three years.

The new legs, delivered to R2 on Easter Sunday morning, were funded by NASA’s Human Exploration and Operations and Space Technology mission directorates. They will make R2 mobile and give it the means to help the ISS crew with regular and repetitive tasks, inside and outside the station, such as cleaning chores and fetching things.

Each leg is 1.2 meters long and will enable Robonaut to climb and move around the 420-km-high outpost.

"Legs are going to really kind of open up the robot's horizons," said Robert Ambrose from NASA's Johnson Space Center in Houston.

With new legs, R2 will be at least 2.5 meters tall. Their design was based on the tether attachments used by spacewalking astronauts.

According to Ambrose, the legs look "a little creepy" when they move because of the number of joints - seven - and a device on the robot’s ‘feet’ called an end effector, which allows the robot to take advantage of handrails and sockets inside and outside the station. Each effector has a light, camera and sensor for building 3D maps.

“Imagine monkey feet with eyes in the palm of each foot,” said Robert Ambrose from NASA’s Johnson Space Center in Houston, "I hope my knee never bends that many degrees, but Robonaut has no problems at all."

An amazing film about a simple man. It's 12 minutes but worth it.

" When 78-year-old runner Bill Iffrig, the runner in the orange singlet -- or the Fallen Man, as this website called him in a blog post written just minutes after the bombing -- was knocked off his feet by an explosion a few yards from the finish of the 2013 Boston Marathon, he was unwittingly thrust into an international media spotlight. Video images of the bomb's shock wave buckling Iffrig's knees and sending him sprawling beamed around the world in an instant. The iconic photo of Iffrig on the ground with three policeman hovering over him became the signature image of the event and landed on the cover of that week's issue of Sports Illustrated.

But those pictures recorded a mere fraction of the story. And they certainly didn't reflect the whole of Bill Iffrig. What they didn't show was what happened next: Iffrig, a retired mill worker from Lake Stevens, Wash., got up, checked himself for blood, and finished the race. Despite losing hearing in his left ear and suffering a right quadriceps injury, the runner got up and put one foot in front of the other, and did what he came to Boston to do. He finished fourth in his age group."

Amazing "El Gordo" Cluster Galaxy
NASA Hubble Team Finds Monster "El Gordo" Galaxy Cluster Bigger Than Thought

Interesting news from NASA.

NASA's Hubble Space Telescope has weighed the largest known galaxy cluster in the distant universe, catalogued as ACT-CL J0102-4915, and found it definitely lives up to its nickname -- El Gordo (Spanish for "the fat one").

By measuring how much the cluster's gravity warps images of galaxies in the distant background, a team of astronomers has calculated the cluster's mass to be as much as 3 million billion times the mass of our sun. Hubble data show the galaxy cluster, which is 9.7 billion light-years away from Earth, is roughly 43 percent more massive than earlier estimates.

The team used Hubble to measure how strongly the mass of the cluster warped space. Hubble's high resolution allowed measurements of so-called "weak lensing," where the cluster's immense gravity subtly distorts space like a funhouse mirror and warps images of background galaxies. The greater the warping, the more mass is locked up in the cluster.

"What I did is basically look at the shapes of the background galaxies that are farther away than the cluster itself," explained lead author James Jee of the University of California at Davis. "It's given us an even stronger probability that this is really an amazing system very early in the universe."

A fraction of this mass is locked up in several hundred galaxies that inhabit the cluster and a larger fraction is in hot gas that fills the entire volume of the cluster. The rest is tied up in dark matter, an invisible form of matter that makes up the bulk of the mass of the universe.

Though equally massive galaxy clusters are found in the nearby part of the universe, such as the Bullet cluster, nothing like this has ever been discovered to exist so far back in time, when the universe was roughly half its current estimated age of 13.8 billion years. The team suspects such monster galaxy clusters are rare in the early universe, based on current cosmological models.

Solar-powered plane aims for round-the-world flight

A new solar-powered plane that will be used to fly around the world in five consecutive days without using any fuel was unveiled Wednesday in Switzerland.

Pilots Andr Borschberg and Bertrand Piccard revealed the futuristic flying machine in a ceremony in Payerne before an audience of industry officials, reporters and dignitaries. The solar plane, named Solar Impulse 2, will be used to circumnavigate the globe in 2015, with the Swiss pilots hoping to accomplish the first around-the-world flight in a solar-powered aircraft.

"Today, we are one step closer to our dream of flying around the world on solar power," Piccard said at today's event. 

Piccard described his pride in showcasing the Solar Impulse 2 plane, and said the aircraft represents true pioneering spirit, as many aviation experts initially said it would be impossible to engineer such a lightweight but resilient solar plane.

"When Solar Impulse was born 12 years ago, and we could show the enormous wings and the light weight of its structure on computer designs, all the specialists in the world of aviation started to laugh," he said. "Today, this airplane exists. It's the most incredible airplane of its time. It can fly with no fuel, day and night, and we hope that we can make it around the world."

Last year, Borschberg and Piccard flew a first-generation prototype of the Solar Impulse plane on a record-setting coast-to-coast flight across the United States. The journey from California to New York took two months, and included five planned stops. Solar Impulse ended its cross-country flight in New York City, touching down at John F. Kennedy International Airport on July 6, 2013.

The Solar Impulse planes are the first to be able to fly day and night without any onboard fuel. The ultra-lightweight planes are powered entirely by  solar panels and batteries, which charge during the day to allow the plane to fly even when the sun goes down.

Since last year's flight, engineers have made adjustments to the design of the solar plane in preparation for the around-the-world mission. Since Borschberg and Piccard will be flying for longer periods, and across greater distances, engineers worked to improve the quality of the plane's onboard batteries and used revolutionary materials to lighten the plane, thereby making Solar Impulse 2 more energy-efficient.

Solar Impulse 2 has a wingspan that stretches 236 feet, longer than a Boeing 747 commercial jet. The wings are covered with 17,000 solar cells that power the plane's various systems, according to company officials.

The upgraded aircraft also features a larger cockpit with better ergonomic designs, which will help Borschberg and Piccard live comfortably in the space during the nearly weeklong flight.

Solar Impulse 2 will undergo a series of test flights in May, followed by training flights over Switzerland, company officials said. Borschberg and Piccard are aiming to begin their round-the-world journey in March 2015.

The plane will take off from the Gulf region, and will fly over the Arabian Sea, China, the Pacific Ocean, the United States, the Atlantic Ocean and Southern Europe or North Africa, Solar Impulse officials said. Landings will be made every few days to change pilots and to accommodate outreach events with participating governments and schools.

The Solar Impulse initiative is designed to raise awareness about and demonstrate the potential of clean energy solutions.

"Solar Impulse is one example of what we can do when we believe that we can achieve the impossible, and this brings hope," Piccard said. "But part of this hope is about clean technologies technologies that allow [us] to protect humankind."

Its wings are a little bit cumbersome.

I always try to do the right thing.
 “Through our eyes, the universe is perceiving itself. Through our ears, the universe is listening to its harmonies. We are the witnesses through which the universe becomes conscious of its glory, of its magnificence.” ― Alan Wilson Watts 

 “The atoms of our bodies are traceable to stars that manufactured them in their cores and exploded these enriched ingredients across our galaxy, billions of years ago. For this reason, we are biologically connected to every other living thing in the world. We are chemically connected to all molecules on Earth. And we are atomically connected to all atoms in the universe. We are not figuratively, but literally stardust.” ― Neil deGrasse Tyson 

"We are one". The above quotes and the simple preceding three word sentence, most clearly define me. Thanks for visiting. :-)
