Say hi to the A7 security robot, one of the newest robots from Knightscope. Knightscope builds robots they hope will predict and prevent crime. Their K5 robot went viral when it had a little mishap by falling in water. The new A7 is a multi-terrain robot that moves like a crab. It's intended for patrolling large areas like an airfield and can go up to 3 mph. It will be shipped as a beta prototype in early 2018. Knightscope says their bots have already helped catch criminals, but they don't fight back against humans. They can scan license plates, use lasers, alert security guards and are equipped with thermal cameras. Watch your back, the A7 may be watching you in the future.

This studio floats under a bridge. The project is from furniture designer Fernando Abellanas. The secret bridge studio is in Valencia, Spain. Getting to the workspace takes some ingenuity. To get to the studio, you ride in a cart operated by a hand crank. It's a metal and plywood box that travels under the bridge.

Everything else is already attached to the wall. The doors to the studio close for privacy, or sleeping. The studio was not officially sanctioned by the city. Abellanas plans on creating more spaces in unused places.

SpaceX launched its most impressive rocket yet on Feb. 6, the Falcon Heavy. The launch was a brilliant success. It sent Elon Musk's Tesla roadster into space! But not everything went according to plan.

SpaceX wanted to land 3 rockets that day. But only 2 made it back to Earth in one piece. The Falcon Heavy is a beast, fueled by 3 main parts. Two booster rockets on the side and one core stage in the center.

Each part runs on 9 engines. That's 27 total engines it takes to lift this rocket to space. The two side boosters landed at Cape Canaveral Air Force Station. The center core was supposed to land on a drone ship in the ocean. But it missed the mark by 328 feet and crashed into the Atlantic instead.

Now we know why.

Rockets save a little fuel in their tanks for landing. It fuels the engines that fire to slow down the rocket. But two-thirds of the central core's engines didn't fire on landing. Six days after the crash, Musk tweeted the reason: "Not enough ignition fluid to light the outer two engines after several three engines relights. Fix is pretty obvious."

Crashes like this aren't new for SpaceX. In fact, it released a video of all its fails back in 2017. SpaceX is famous for learning from its failures to fix them the next time around. On the same day, Musk revealed more news. 

SpaceX is currently building a second drone ship that will sail off Florida's coast. The two ships will be there for ocean landings of Falcon Heavy's side boosters. There is at least 2 more Falcon Heavy mission scheduled for 2018.

AT&T dominated the telephone market for most of the 20th century. The company was so big, it was forced to break up into eight smaller companies in 1984. Today, almost all of those companies are once again part of AT&T, along with cellular carriers and cable providers. Here's how the company grew so big that the government broke it up — only to see it become even bigger.
