Safe mode, huh? While we had previously assumed only our clearly cursed PCs could fall into such a dark, dark place, apparently we were badly mistaken. The recently launched Giove-B satellite, which is the second bird launched for Europe's next-gen satnav network, was recently sent into some sort of "safe mode" after being "rocked by a surge of space radiation." Reportedly, said mode halts the satellite's mission activities and forces it to "concentrate on keeping its batteries topped up by ensuring its solar panels are properly aligned with the sun." Thankfully, the poor Giove-B was able to resume its frolicking in outer space around a fortnight after being blasted, though we hear if it had been just a tad worse, ground control would've had a real mess on their hands with the Blue Screen of Death.

The Professor rounds up a handful of interesting and informative gadget-related science stories from the week and presents them in an easily digestible liquid form.

This week is quickly becoming a tough one for the aerospace industry, as just a day after NASA reported tampering on an ISS bound computer, an explosion at the Mojave Air and Space Port has claimed two lives and seriously injured four others. The blast reportedly occurred during a "test of a new rocket motor for SpaceShipTwo -- a spaceship being built for Virgin Galactic, Richard Branson's space tourism company." According to a spokeswoman for the spaceport, the blast was "on a remote pad" at an airport home to Scaled Composite (which is the builder of the first private manned rocket to reach space), but the firm's founder Burt Rutan wasn't in attendance when the "cold fire test" went awry.

If you thought hoisting a giant banana above Texas was outrageous, you may indeed chuckle to learn that a 1,400-pound refrigerator-sized container of ammonia will be jettisoned from the International Space Station next week. On July 23rd, to be precise, Expedition 15 crew member Clayton Anderson will have the, um, privilege of heading outside in order to toss "two large hunks of unneeded equipment towards Earth," and once ejected, they will be tracked by NASA for an entire year until they finally begin to enter the atmosphere. Notably, officials are still not sure where the debris will land just yet, but if you happen to find your fridge replaced with a partially disintegrated (albeit similarly sized) container of fetid material in the next year or two, you'll know exactly what went awry.

While there's long since been ways to get a piece of your mind (or your best Photoshop effort) launched into space, getting your person up there isn't exactly feasible if your pay stub isn't stamped by NASA. Now, however, Space Adventures is looking to hoist a pair of untrained civilians into space in 2008 and 2009 aboard a Soyuz craft, and the firm will soon be selling seats for the low, low price of $100 million apiece. The Lunar Mission will eventually bring you "to the other side of the moon," and while we're sure the itinerary is quite detailed considering the price of admission, the firm isn't dolling out too much more until you prove your bank account is stocking the required dough.

It seems like it was just yesterday when ASTRO and NextSat took to the skies galaxy in hopes of making their creators proud, but now the time has come for the two to wind down and sip exotic liquids from an umbrella-adorned glass. Thankfully, this story has somewhat of a gleeful ending, though it wasn't looking so rosy just days ago; on June 27th, the two parted ways and managed to drift some seven-kilometers apart before ASTRO used its onboard camera system (and a bit of help from ground control) to navigate back to NextSat, where it then proceeded to give its space-bound buddy a theoretical noogie. Sadly, this final scenario marks the final test in DARPA's Orbital Express demonstration, which means that the two machines now have an ominous decommission plan to look forward to.

Although we're not quite ready to pony up for a ticket to space just yet, billionaire Robert Bigelow is thinking way into the future by trialing a space hotel. Dubbed Genesis II, the inflatable module could eventually be used as a "hotel in space" or double as a manned space station, and considering that it only inflates once it settles in orbit, the cost of launching is substantially decreased. The experimental craft was successfully launched on board a Russian rocket, and has since established communications and "beamed back a series of images of its expanding solar panels." This endeavor is just the beginning, however, as Bigelow envisions a "full-scale space hotel" to be named Nautilus, and if you're interested in helping out (and making $50 million on the side), you've got three years to "design a craft capable of carrying five people to a height of 250 miles."

Looks like Summer Infant has a whole lot of explaining to do after one of its baby monitors has reportedly been able to "pick up black-and-white video from inside the space shuttle Atlantis." A Chicago-based mother probably had uncomfortable flashbacks to Signs after her newly purchased monitoring system chose to broadcast video of the mission right on the screen, but a NASA spokeswoman has already deflated hope that it was somehow coming directly from the shuttle. Apparently, a live feed is also available on NASA's website, which is leading investigators to focus on more earthly origins -- the mom, however, will probably just cancel her cable and keep on watching intently "to see what happens next."

While just being in the presence of a full scale Gundam makes it worth the price of admission, we'd speculate that talking a stroll in the Land Walker would fall more into the thrill ride category. Of course, rocketing from ground zero into outer space takes things (almost) to another level galaxy, and that's precisely what NASA's Shuttle Launch Experience gives you a taste of. The $60 million attraction opened up yesterday to a team of nearly 40 astronauts, some of which reportedly said that the ride managed to best actual training simulators in terms of sheer realism. Apparently, the ride takes passengers through a simulated shuttle launch, and utilizes 13-channels of surround sound, rumbling seats, and an 84-inch HD screen to terrorize (in a good way) riders. Granted, we'd have no idea what cruising around at 17,500 miles-per-hour feels like, but for folks visiting the Kennedy Space Center, feel free to chime in if you can put it into words.

If you thought ASTRO and NextSat were the only two autonomous robots frolicking around in testing environments, Raven would certainly beg to differ, as NASA has recently announced that the University of Washington's mobile surgical robot will soon be off to tackle surgical tasks whilst underwater. The 12th NASA Extreme Environment Mission Operations test will see the mechanical MD pick up the tools in a simulated spacecraft submerged near Key Largo, Florida, where the "mission will test current technology for sending remote-controlled surgical robotic systems into space." Thanks to a combination of wired and wireless networks, a trio of seasoned veterans back in Seattle will be dictating the movements remotely, as the bot attempts to "suture a piece of rubber and move blocks from one spindle to another." Interestingly, there was no word on whether Raven was scheduled to pick up the night shift at Seattle Grace upon its return from the depths.

While we've no idea how much the Mars Global Surveyor actually cost to construct, launch, and manage whilst hovering around in space, it's entirely likely that a single human error wiped out even more than was initially lost by the Alaska Department of Revenue earlier this year. Sad to say, galaxy geeks everywhere now have a scapegoat to direct their wrath at, as a review board of the mishap found that "a single command (root@mars-surveyor: rm -rf /) that oriented the spacecraft's main communications antenna was sent to the wrong address," subsequently leading to a cataclysmic series of events that finally dismantled its communication system. Interestingly, the command caused the befuddled craft to think that one of its solar panels was "stuck," which eventually led to an autonomous decision to enter "safe mode," followed by a complete shutdown of the unit's onboard batteries. Intelligently, the LA Times report neglected to mention any specific culprit, and hey, living with the guilt of destroying the machine that showed us so much of the Red Planet is probably punishment enough.

Don't say we didn't warn you, as just days after ASTRO and NextSat successfully completed an autonomous fuel transfer whilst orbiting, the thoughtful duo is already looking forward to the next big challenge. As Scenario 0 operation trials continue, the ASTRO satellite will utilize its "ten-foot-long robotic arm to move objects to NextSat," the first of which will purportedly be a "spare battery transfer" that will be "snatched from ASTRO and plugged into NextSat." Reportedly, this very battery will be the focal point of a number of future handoffs, and a "secondary sensor processing computer" will eventually be offloaded to NextSat as well if the arm cooperates. Of course, these relatively minor exchanges don't mark the end of the work week for these two, as a number of future scenarios look to provide increasingly difficult challenges for "mating" the two machines. Hey, we've already got robotic rights in the works, so we're looking that way for guidance about handling these newfangled (and slightly awkward) mechanical relationships, cool?

Launching a few birds into space is quite a feat in its own right, but pumping hydrazine fuel into an orbiting counterpart autonomously is really something to be proud of. Just about a month after launching the two unmanned crafts into space, the ASTRO satellite "successfully pumped vital hydrazine fuel into its NextSat counterpart as part of Scenario 0-1, the first in a series of increasingly challenging tests." The machines are currently taking part in the series of Orbital Express missions, and apparently, things are on the up and up thus far. Future tests are slated to include "autonomous undocking, proximity operations and re-docking," as well as installing a battery on NextSat with its robotic arm. We can't wait to see what happens when one of the two gets testy about refueling after hours, but we sure hope the galactic battle is somehow caught on tape.

Now that humans have shot themselves up into space, frolicked on the moon, and have their own space station just chillin' in the middle of the galaxy, what's really left to accomplish out there? How about cruising around at light speed? Apparently, a boastful group of scientists at the Bae Institute in Southern California feel that they're one step closer to achieving the impossible, as the "world's first photonic laser thruster" was purportedly demonstrated. Using a photonic laser and a sophisticated photon beam amplification system, Dr. Bae reportedly "demonstrated that photonic energy could generate amplified thrust between two spacecraft by bouncing photons many thousands of times between them." The Photonic Laser Thruster (PLT) was constructed with off-the-shelf parts and a bit of fairy dust, and it's said that this invention could eliminate the need for "other propellants" on a wide range of NASA spacecrafts, theoretically savings millions on energy costs and enabling longer missions. So while this may be an incredibly novel idea, the chances of this actually working outside of a laboratory seem relatively small, and make sure we're not the guinea pigs strapped into the first craft that utilizes this mystical method of launching, cool?
