New System Propels Satellites Without Propellants 85

cylonlover writes "Astronauts on the International Space Station (ISS) are testing a new propulsion system ... inside the station. While this might seem like the height of recklessness, this particular system doesn't use rockets or propellants. Developed in the University of Maryland's Space Power and Propulsion Laboratory, this new electromagnetic propulsion technology called the Resonant Inductive Near-field Generation System (RINGS) uses magnetic fields to move spacecraft as a way to increase service life and make satellite formation flying more practical."

Four Month Mars Food Study Wraps Up 142

After four months in a mock space habitat in Hawaii, participants in a study to determine how best to feed astronauts (HI-SEAS) on a mission to Mars emerged yesterday. A few days ago, the mission commander was interviewed in Astrobiology Magazine, noting the most successful foods: "There's also been a lot of really good cooked dishes. Some of our crew members are accomplished cooks, and every week there are different surprises. Some success meals were Russian borscht, Moroccan tagine, enchilasagna, seafood chowder, and fabada asturiana. Wraps work really well: we combine tortillas, different vegetables, Velveeta cheese, and sausage or canned fish into ever-changing combinations. This is actually in line with the success of tortillas at the ISS. In general, the dehydrated and freeze-dried vegetables are a real success. They're used on a daily basis in almost every meal." The crew kept weblogs, and did other things than just sit around and eat: some studied robotics and they went on a few simulated EVAs.

Could Humanity Really Build 'Elysium'? 545

Hugh Pickens DOT Com writes "Miriam Kramer writes at Space.com that in the new movie Elysium, Earth is beyond repair, and the rich and powerful have decided to leave it behind to live in a large, rotating space station stocked with mansions, grass, trees, water and gravity. 'The premise is totally believable to me. I spent 28 years working on NASA's International Space Station and retired last summer as the director of ISS at NASA Headquarters. When I took a look at the Elysium space station, I thought to myself, that's certainly achievable in this millennium,' says Mark Uhran, former director of the International Space Station Division in NASA's Office of Human Exploration and Operations. 'It's clear that the number-one challenge is chemical propulsion.' Nuclear propulsion could be a viable possibility eventually, but the idea isn't ready for prime time yet. 'We learned an incredible amount with [the International Space Station] and we demonstrated that we have the technology to assemble large structures in space.' The bottom line: 'If you threw everything you had at it, could you reach a space station of the scale of Elysium in 150 years?' says Uhran. 'That's a pretty tall order.'"

Video Jon Oxer Talks About the ArduSats That are On the Way to ISS (Video) 17

Two ArduSats were launched last week from Japan, along with an ISS resupply package, and on August 9 this payload is due to arrive at the International Space Station. Jon Oxer is a co-founder of Freetronics, a company that sells Arduino-based products, so he has a vested interest in ArduSat's success. He's also a major Free Software booster, which may be part of the reason he was at OSCON -- where Timothy Lord and his camcorder caught up with him. BTW: This is the same JAXA (Japan Aerospace Exploration Agency) launch that is carrying the first talking humanoid robot to go into space from Earth. So this launch is not only "a giant leap for robots," as Japanese robot Mirata famously said, but is also a good-sized step for Arduinos. And for CubeSats, too.

Elon Musk Admits He Is Too Busy To Build Hyperloop 253

DavidGilbert99 writes "It sounded like the future — a 600mph train taking people from San Francisco to Los Angeles in just 30mins. In fact it sounded like a future too good to be true. And so it seems to have proven. As Alistair Charlton at IBTimes reports, Elon Musk, the man behind PayPal, Tesla and Space X has admitted that Hyperloop is a step too far and he should never have mentioned it in the first place — 'I think I shot myself in the foot by ever mentioning the Hyperloop. I'm too strung out.' Oh well, let's hope SpaceX works out a bit better ... " Considering that SpaceX has already sent materials to the ISS and retrieved the capsule, it seems to have worked out pretty well so far.

Former Director of the ISS Division At NASA Talks About Science Behind 'Elysium' 366

Nerval's Lobster writes "In the new movie 'Elysium,' Earth a century and a half from now is an overtaxed slum, low on niceties like clean water and riddled with crime and sickness. The ultra-rich have abandoned terra firma in favor of Elysium, an orbital space station where the champagne flows freely and the medical care is the best possible. Mark Uhran, former director of the International Space Station Division at NASA headquarters, talked with Slashdot about what it would take (and how much it would cost) to actually build a space station like that for civilians. It turns out NASA did a report way back in 1975 describing what it would take to build a Stanford torus space station like the one in the movie: rotation for artificial gravity, a separate shield for radiation and debris, the ability to mine materials from astroids or possibly the moon, and $190.8 billion in 1975 dollars (the equivalent of $828.11 billion today). Looks like the ultra-rich are stuck on Earth for the time being." And still artificial gravity experiments languish.

Russian Vehicle Delivers Spacesuit Repair Kit To ISS 39

A Russian spacecraft has successfully delivered new supplies to the ISS. Crucially, its payload is meant to prevent a repeat of the aborted spacewalk of earlier this month. Says the article:: "The cargo ship is loaded with nearly 3 tons (2.7 tonnes) of food, fuel, hardware and science experiment equipment for the six-person crew of the station's Expedition 36 mission. Among its cargo is a set of tools intended to help the astronauts investigate and patch up the spacesuit that malfunctioned during a July 16 spacewalk outside the orbiting laboratory."

DIY Satellite Tracking 30

Travis Goodspeed has authored a blog post detailing his method of tracking low-earth-orbit satellites. Starting with an old Felcom 82B dish made for use on maritime vessels, he added motors to move it around and a webcam-based homemade calibration system. "For handling the radio input and controlling the motors, I have a BeagleBone wired into a USB hub. These are all mounted on the trunk of the assembly inside of the radome, sending data back to a server indoors. ... In order to operate the dish, I wanted both a flashy GUI and concise scripting, but scripting was the higher priority. Toward that end, I constructed the software as a series of daemons that communicate through a PostgreSQL database on a server inside the house. For example, I can run SELECT * FROM sats WHERE el>0 to select the names and positions of all currently tracked satellites that are above the horizon. To begin tracking the International Space Station if it is in view, I run UPDATE target SET name='ISS';. For predicting satellite locations, I wrote a quick daemon using PyEphem that fetches satellite catalog data from CelesTrak. These positions are held in a database, with duplicates filtered out and positions constantly updated. PyEphem is sophisticated enough to predict in any number of formats, so it's easy to track many of the brighter stars as well as planets and deep-space probes, such as Voyagers 1 and 2."

Spacewalk Aborted When Water Fills Astronaut's Helmet 125

astroengine writes "A planned six-hour spacewalk outside the International Space Station came to a dramatic and abrupt end on Tuesday when water started building up inside the helmet of Italian astronaut Luca Parmitano. Parmitano and NASA astronaut Chris Cassidy were less than an hour into their spacewalk, their second in a week, when Parmitano reported that his head felt wet. 'My head is really wet and I have a feeling it's increasing,' Parmitano reported to ground control teams at the Johnson Space Center in Houston. Parmitano returned safely to the space station interior, but the cause of the leak was not immediately known."

How NASA Steers the Int'l Space Station Around Asteroids & Other Debris 44

willith writes "I got to sit down with ISS TOPO Flight Controller Josh Parris at the Houston Mission Control Center and talk about how NASA steers all 400 tons of the International Space Station around potential collisions, or 'conjunctions,' in NASA-parlance. The TOPO controller, with assistance from USSTRATCOM's big radars, keeps track of every object that will pass within a 'pizza-box'-shaped 50km x 50km x 4km perimeter around the ISS. Actually moving the station is done with a combination of large control moment gyros and thrusters on both the Zvezda module and visiting vehicles. It's a surprisingly complex operation!"

With Catastrophes In Mind, Supercomputing Project Simulates Space Junk Collision 15

aarondubrow writes "Researchers at The University of Texas at Austin developed a fundamentally new way of simulating fabric impacts that captures the fragmentation of the projectiles and the shock response of the target. Running hundreds of simulations on supercomputers at the Texas Advanced Computing Center, they assisted NASA in the development of ballistic limit curves that predict whether a shield will be perforated when hit by a projectile of a given size and speed. The framework they developed also allows them to study the impact of projectiles on body armor materials and to predict the response of different fabric weaves upon impact." With thousands of known pieces of man-made space junk, as well plenty of natural ones, it's no idle concern.

Cute Japanese Robots To Be Launched Into Space 90

astroengine writes "This summer, the Japan Aerospace Exploration Agency (JAXA) plans to launch two amazingly cute yet advanced, white-helmeted robots into space. Then an astronaut aboard the International Space Station (ISS) will attempt to converse with one of them. Robot astronaut Kirobo and backup robot Mirata were created as part of the Kibo Robot Project, a collaboration among Robo Garage, Toyota, the University of Tokyo and the Japan Aerospace Exploration Agency JAXA. They aim to send the robots with the JAXA mission to the ISS on Aug. 4."

IBM Buys Dallas Based Softlayer For $2 Billion 78

An anonymous reader writes "IBM this morning announced a deal to acquire the Dallas based hosting company Softlayer, the largest privately held cloud computing provider in the world. Formerly known as The Planet, they have a dark past and hopefully a bright future. Interesting that ISS and Softlayer will now be under the same roof. 'IBM will integrate SoftLayer’s public-cloud services with its own IBM SmartCloud portfolio. In theory, that will allow IBM to more speedily deliver a combination of private, public and hybridized cloud platforms to business clients. CloudLayer features include the ability to deploy virtual cloud servers (with processors 2.0GHz or faster), a content-delivery network with scalability and security, an object-storage platform based on OpenStack Object Storage, and private-cloud solutions.'"

Mice, Newts Retrieved After a Month Orbiting Earth At 345 Miles Up 85

The Associated Press (as carried by the Washington Post) reports that a living payload of newts and mice has been retrieved after a month orbiting earth in a Russian space capsule at an altitude of 345 miles, far higher than the ISS's orbital distance of 205 miles. Says the story: "Fewer than half of the 53 mice and other rodents who blasted off on April 19 from the Baikonur Cosmodrome survived the flight, Russian news agencies reported, quoting Vladimir Sychov, deputy director of the Institute of Medical and Biological Problems and the lead researcher. Sychov said this was to be expected and the surviving mice were sufficient to complete the study, which was designed to show the effects of weightlessness and other factors of space flight on cell structure. All 15 of the lizards survived, he said. The capsule also carried small crayfish and fish."

Astronauts Fix Phantom Space Station Ammonia Leak 54

astroengine writes "During an unscheduled spacewalk on the space station's exterior on Saturday morning, NASA astronauts Tom Marshburn and Chris Cassidy carried out the mother of all plumbing jobs: They detached a suspect ammonia pump, replaced it with a spare and watched for any further ammonia leakage. The emergency spacewalk was carried out in response to a troubling ammonia coolant leak that was discovered on Thursday. The coolant is used to maintain the temperature of the vast solar arrays the space station uses to generate electricity for its systems. 'It will take some diagnostics, still, over the course of the next several days by the thermal systems specialists to fully determine that we have solved the problem of the ammonia leak," said NASA commentator Rob Navias during the live NASA TV spacewalk broadcast. 'But so far, so "good."'"

Chris Hadfield, an astronaut currently on the ISS, described it in his Twitter feed as 'a small stone from the universe.' He also said he was glad it didn't hit the hull. Jim Scotti, a planetary scientist from the University of Arizona, thinks the object may have had a different origin: 'It's unlikely this was caused by a meteor; more likely a piece of man-made space debris in low Earth orbit.'"

Privately Built Antares Test Flight Successfully Launched From Virginia 85

After high winds (up to 140mph) delayed yesterday's scheduled launch (itself a re-do because of a cabling problem), Orbital Science's Antares rocket has made it to space. This launch was a test run, but Antares is intended to launch supplies to the ISS. Space.com reports: "The third try was the charm for the private Antares rocket, which launched into space from a new pad at NASA's Wallops Flight Facility, its twin engines roaring to life at 5 p.m. EDT (2100 GMT) to carry a mock cargo ship out over the Atlantic Ocean and into orbit. The successful liftoff came after two delays caused by a minor mechanical glitch and bad weather." Congratulations to all involved.
