Progress 38 docks at second attempt

The International Space Station crew successfully captured the Progress 38 spacecraft yesterday, after the unmanned Russian supply vessel sailed past the orbiting outpost on Friday.

A telemetry failure 25 minutes before the scheduled docking prompted last week's unscheduled flyby. The cause was a glitch in the TORU teleoperated rendezvous and docking system, provoked by "the activation of the TORU 'Klest' TV transmitter*, which created interference with TORU itself", NASA explains.

Ex UK.gov top boffin's amazing claim

The long-touted idea of using airships to replace cargo aircraft is in the news again, courtesy of former head government boffin Professor Sir David King, who says "this is something I believe is going to happen".

King's remarks were reported by the Guardian this week. The former UK chief scientific adviser, nowadays turned big cheese at Oxford uni, was addressing a green biz forum there.

NASA firms up dates for final two flights

NASA has announced that the last space shuttle mission - Endeavour's STS-134 to the International Space Station - will now lift off on 26 February next year.

Discovery's STS-133 mission, meanwhile, is scheduled for 1 November. NASA explains: "The target dates were adjusted because critical payload hardware for the STS-133 mission will not be ready in time for the previously targeted date. With Discovery's move, Endeavour had to plan for its next available window, which was February."

Robotic cargo spacecraft misses rendezvous with ISS

Zooms past as crew members watch

An unmanned Russian cargo ship missed its scheduled rendezvous with the International Space Station on Friday after a telemetry lock between the two spacecraft failed. Engineers are scrambling to figure out why.

The robotic Progress 38 spacecraft sailed past the station as its crew tried in vain to regain telemetry with the it, NASA officials said. The ship was a couple miles away from the station when it zoomed by, so it never posed a threat to the six-person crew.

"The Progress literally flew past the station, but at a safe distance from the outpost," NASA commentator Rob Navias said. "The station crew reported seeing the Progress drift beyond their view, as they worked to reestablish telemetry with the spacecraft."

Superpowered energy-storing wonder stuff created in lab

Future exploding laptop battery = nuclear bomb going off

US-based boffins say they have created a never-seen-before type of ultra-bizarre stuff in the lab by using incredible pressures similar to those found deep inside planets. The scientists believe that their creation is capable of storing an unfeasible amount of energy.

"It is the most condensed form of energy storage outside of nuclear energy," says Choong-Shik Yoo, chemistry prof at Washington State uni.

Yoo and his colleagues created "novel two- and three-dimensional extended non-molecular phases" of xenon difluoride (XeF2) by squashing their samples incredibly viciously. This was done using two small "anvils" made of diamond, rammed together by powerful machinery.

Meet the Eyeborg: Canadian Man Replaces Eye with Video Camera

A Canadian man has replaced his own false eye with a camera-eye of his own invention - and will let the world see what he sees via a live video link.


Rob Spence, a Toronto-based film-maker, lost his right eye in a shooting accident on his grandfather's farm when he was a teenager. Now 36, he decided some years ago to build a miniature camera that could be fitted inside his false eye. A prototype was completed last year, and was named by Time magazine as one of the best inventions of 2009. He calls himself "the Eyeborg guy".

The eye contains a wireless video camera that runs on a tiny three-volt battery. It is not connected to his brain, and has not restored his vision. Instead it records everything that he sees.

More than that, it contains a wireless transmitter, which allows him to transmit what he is seeing in real time to a computer.

Iran Unveils Human-Like Robot

Iran has developed a new human-like walking robot to be used in "sensitive jobs," government newspaper Iran reported on Sunday.

Soorena-2, named after an ancient Persian warrior, was unveiled by President Mahmoud Ahmadinejad on Saturday. It is 1.45 metres (4.7 feet) tall and weighs 45 kilograms (99 pounds), the report said.

"Walking slowly like human beings with regular arm and leg movements are among its characteristics," it said. "Such robots are designed and developed to be used in sensitive and difficult jobs on behalf of a person or as help."

The report did not elaborate on the robot's capabilities.

Apple's iPhone Mea Culpa: We're "Totally Wrong"

Company admits it uses the wrong formula to compute iPhone signal strength

For two weeks, Apple dismissed rumors of a faulty antenna in the new iPhone 4 as nothing more than scuttlebutt. Any phone has these problems, Apple officials said. Buy a case to fix it.

Friday, Apple came clean: The antenna works just fine. But the software that displays signal strenth doesn't. The company has been using a faulty formula to determine signal strength in its phones for years.

"Upon investigation, we were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong," Apple said in a letter from two executives posted on its website Friday morning.

Supernovae don't make the biggest atoms

They are the brightest of stars, but supernovae may not forge the heaviest elements. That's the suggestion arising from analysis of a new model of the particle winds that rush from the cores of supernovae.

The only two elements formed in abundance shortly after the big bang were hydrogen and helium. All the heavier ones must have been forged by fusing these smaller nuclei together. The high pressures and temperatures inside ordinary stars can account for elements up to a certain size, but making elements bigger than iron, which has a nucleus containing 26 protons, requires some other mechanism.

That's where supernovae come in. These exploding stars blast neutrinos from their cores to their surface at close to the speed of light, kicking protons and neutrons out of other atoms as they go. This creates a "wind" within which neutrons and protons fuse to form the nuclei of small atoms. Further protons, neutrons and atoms join in to make larger ones.

David Livingstone Letter Deciphered At Last

London - The contents of a long-illegible letter written by famed 19th century explorer David Livingstone have finally been deciphered, a British university said Friday, nearly 140 years after he wrote of his despair at ever leaving Africa alive.

Researchers say that the letter - which required state of the art imaging techniques to decipher - helps round out the picture of a man traditionally cast as an intrepid Victorian hero, revealing the self-doubt that tormented the missionary-explorer in one of his darkest hours.

"I am terribly knocked up but this is for your own eye only," Livingstone wrote to close friend Horace Waller in the newly revealed correspondence. "Doubtful if I live to see you again."

Livingstone was a national hero when he set off to find the source of the River Nile in 1866, but by the time he composed his four-page missive he was at the lowest point in his professional life, according to Debbie Harrison, a researcher at Birkbeck University of London.
