Article: Billionaire Dennis Tito, tired of being told that we can't send humans to Mars just yet, on Wednesday revealed his scheme for launching two astronauts to the red planet as early as December 2017. Titled "Inspiration Mars," the flyby mission would exploit a rare line of Earth and Mars that minimizes the time and the fuel it would take to get to Mars and back home again. The astronauts would come within 100 miles of the Martian surface before being taken back to Earth. "It would be a voyage of around 800 million miles around the sun in 501 days," Tito testified Wednesday at a hearing of the House subcommittee on space. "No longer is a Mars flyby mission just one more theoretical idea. It can be done. Not in a matter of decades, but in a few years." Tito is a former engineer who made a fortune in investment management and, in 2001, became the first person to pay his way into space, buying a seat on a Russian rocket. Now he's pitching Inspiration Mars as a national priority for the United States. Grab this rare chance to go to Mars quickly or risk seeing China or Russia get there first, he told members of Congress. Tito mentioned a backup plan that would offer Inspiration Mars four more years of development time. Another line of planets in 2021 offers a second chance to go to Mars fairly quickly, but the journey would last 80 days longer and require that the astronauts fly much closer to the sun, within the orbit of Venus, in one portion of the trip. That would add to the already considerable radiation hazards. When Tito talked of the idea of Inspiration Mars early this year, he thought he could use primarily private rockets and minimize the need for NASA involvement. But the possibility study led Tito back to NASA. NASA is building a huge rocket, the Space Launch System, that is supposed to be ready for its originally, uncrewed test flight in 2017. The second launch, carrying a crew in NASA's new Orion capsule for the first time, isn't scheduled until 2021. Tito's plan would essentially borrow the SLS for the...

Article: "Dear anybody. Your email address has been chosen by our computer. So, for no reason, we'd like to give you a million dollars. All you need to do is give us your bank account numbers. Can we interest you in some diet pills? And, by the way, I want to marry you." I hate to let you down, but there is no "million dollars". The diet pills don't exist - and your future "husband" or "wife" has just proposed to a million others. These and a hundred other stories have been made up to steal your personal information or money or maybe just to infect your computer with a virus. Welcome to the world of junk email. Junk email - or spam - is probably the biggest global business that's ever existed. Billions of spam emails are sent every day, making up around 80% of all email traffic. These incredible volumes of spam slow down the whole internet and cost businesses millions of dollars just trying to keep up with the next trick. Your email programme probably includes a spam filter, which sorts out the mail you do want from the junk. But it's impossible to stop it all and if you put together the seconds it takes to see through the deception in each one, they add up to a significant amount of lost time dealing with the spam that does get through. But who could fall for such obvious tricks? Probably very few of us - one in a million, perhaps. But when you are sending billions of these every day, for next to no cost, it doesn't take a genius to work out that someone is getting very rich. But who? It's incredibly difficult to find out. Most spam is sent using anonymous networks of infected computers, called "botnets", some of which are made up of tens of millions of computers across dozens of countries. Maybe your own laptop is sending out marriage proposals right now. It's enough to put you off using email again! So what can you do to defend yourself? You could set up a separate email account for online use, or maybe leave out the @ symbol when you write your email address online. An up-to-date web browser and antivirus...
