Mars-500 Project Third Stage Began
The Mars-500 project is a ground-based experiment simulating manned flight to Mars. The main purpose of the experiment is to evaluate how the long isolation, especially the 20-minutes delayed communication with the outside world, affects the state of health and working capability of the crews.
The project has three stages. The first, 15-day stage took place in 2007 and was only designed to test out the facility. The second, 105-day stage happened in 2009 with 6 volunteers living in the isolated living complex. Currently in progress is the third stage, and another 6 volunteers will actually simulate a complete 520-day mission to Mars -- yes, that's how long the round-trip takes.
The 6 volunteers (professional astronauts, scientists, and engineers) will spend the entire duration of the experiment in a sealed facility with no windows and a '20-minute, one-way time-delay in communications to mirror the real lag in sending messages over the vast distance between Mars and Earth. It's almost like serving an 18-month jail term, but only worse, because they won't ever see the sun and have to live off canned food. They will also be under constant supervision and will be going through many scientific tests each day.
I have always been a big fan of space exploration. Call me Chicken Little if you wish, but with enough nuclear bombs that can blow up our planet over 300 times with only the push of a button, and with so many maniacs in this world, we've got to spread the seeds for human kind before the dooms day, before we wipe out ourselves completely from this universe. Therefore, great shout outs to these 6 volunteers who are willing to make the sacrifice for the benefit of the entire human race (think of all the World Cup games they are going to miss!!). I wish them a very productive "journey" and the greatest success! If I ever get locked up for 18 months, the entire book of Smiling Proud Wanderer would have been translated. LOL!
In order to successfully establish human outposts (or colonies) on another planet, it is essential to have intelligent worker robots working alongside human crews. Although we already have several robots roaming on top of the Martian surface, they are mainly for scientific exploration. What we really need are robots that can work as a team building/assembling equipments and living complexes. Some of them can be sent to Mars before the humans to get things started. Because of the long distance and long communication lag, they would have to be quite capable of autonomous operations, probably at some basic level tasks. Then more robots would go along with the human crews. These robots don't have to be fully autonomous, but will need to be able to interact with human well and take directions/supervisions from human operators efficiently/effectively. Robots have great advantages over human for these kind of space exploration because they don't need to eat, breathe, be entertained, and will never need a psychiatrist during such long space trips.

First time ever a rescue helicopter landing in Bryce Canyon, Utah. The chopper landed right on the top of the ridge. Got to give the pilot some shout out for his awesome skills!

AI and Robots: Who Gave the Robot a Knife?
================================================================

These researchers are from the Institute of Robotics and Mechatronics, part of DLR, the German aerospace agency, in Wessling, Germany, and they share the same dream with me --- that one day robots will be smart enough to take over kitchen duties and free us from the laborious duty of cooking. This task of course requires the robot to be able to handle a knife appropriately, so it can cut, chop, slide or dice during the course of preparing a meal. But what if it accidentally struck a human? With that question in mind, these researchers performed a series of experiment to investigate the severity of possible injuries and also designed a collision-detection to minimize the damage.

The video below shows how the experiments were performed and how the robot arm performed differently with and without the collision-detection system (the real excitement is at the end of video). As a researching in Human-Robot Interaction myself, I couldn't help but imagine this poster in my head that reads, "Volunteer needed for a user study: Get Paid to be Stabbed by a Robot!"
But I am a little bit confused. Once turning on the collision-detection system, the robot will stop cutting/stabbing the human. The human is safe now, and so is that piece of steak! Three hours later, I'd be shouting in starved voice, "Where's my steak dinner?"
Note that the idea of a robot holding a knife would never be allowed in US universities. It would never get approval from the IRB (Institutional Review Board). See, we do things very differently here in the US, instead of knives, we give robots machine guns and missiles!! And there will be no danger to US citizens, because we send these robots to other countries! LOL!

Anyway, I think it will be a long time before we actually have knife-wielding robots that roam our homes. When I program my robots, I actually intentionally make it not touch things such as knives, gas stoves, and explosives. But I bet you this day will eventually come, and a lot of lawyers are going to get rich.

Random Thoughts: Have You Lost Your Soul?
Well, if quickly clicking through things has grown into a habit for you, it's probably time to reconsider it now.
According to this article from Newslite and this article from geeks.com, GameStation, on UK online games retailer, added the "immortal soul clause" to its online purchase agreement basically saying the customers would grant them the right to claim their souls. More than 7,500 customers (88%) agreed to the clause without really reading the agreement details, and now GameStation legally owns thousands of souls. Here below are the exact wording of the sneaky clause:
Luckily, 12% of the customers did notice a small tick box at the bottom of agreement allowing them to opt out of the clause, and earned themselves a £5 gift voucher by doing so. But really, how many of the 12% customers actually read the terms and services agreement? My guess would be very few.By placing an order via this Web site on the first day of the fourth month of the year 2010 Anno Domini, you agree to grant Us a non transferable option to claim, for now and for ever more, your immortal soul. Should We wish to exercise this option, you agree to surrender your immortal soul, and any claim you may have on it, within 5 (five) working days of receiving written notification from gamesation.co.uk or one of its duly authorised minions. We reserve the right to serve such notice in 6 (six) foot high letters of fire, however we can accept no liability for any loss or damage caused by such an act.
If you a) do not believe you have an immortal soul, b) have already given it to another party, or c) do not wish to grant Us such a license, please click the link below to nullify this sub-clause and proceed with your transaction.
Although this probably was part of an April Fool's Day joke (the vouchers were no joke), and GameStation has no intention to ever claim their rights on the souls (in fact, they emailed all customers nullifying the clause), this clearly shows the general public opinion on these agreements. Most people think that if most people don't read these things, they are no longer valid. However, the truth is that they will most likely be legally binding (not the soul clause, of course) unless challenged in a court of law. And do you ever want to get into a legal battle with large companies who employ an army of lawyers?
There are, actually, some people who take these agreements very "seriously!" Anne Loucks from obesso.com created a clever way to get herself out of legal troubles with EULAs. Using a piece of cardboard that reads "Kitty Agrees" with a protruding piece underneath, she would have her cat to step on the board, which pushes the spacebar underneath and agrees to an EULA for her. So worst comes to worst, it would be the cat losing its soul, and not Anne!
Putting aside the legality of these actions of both the businesses and users, clearly the system is not working very well. I know for regular business contracts or terms and agreements, critical elements are required by law to really stand out (bold, larger size, etc.). I am sure a better standard and approach will have to be created soon, because soon or later, somebody is getting sued over this.
