NASA puts never-before-seen Challenger, Columbia shuttle wreckage on display

NASA puts never-before-seen Challenger, Columbia shuttle wreckage on display

As this weekend's failed launch of the latest SpaceX mission demonstrates, space travel and exploration remains a difficult endeavor. It is perhaps fitting then that weekend also saw the opening of a new exhibition from NASA at the Kennedy Space Center Visitor Complex in Florida. On display to the public for the first time ever are pieces of space shuttle wreckage from the Challenger and Columbia missions and their doomed flights. While missions like the recent SpaceX fortunately don't put human lives directly at risk, NASA's new display is part of a fitting tribute to the two crews that were lost.

Norway has built a ‘highway’ for bees

Norway has built a ‘highway’ for bees

It's well-known that bees and their process of pollination play an important part in global food production, and scientists have been concerned for years about the rapidly decreasing numbers of bee populations. So, one environmental group in Norway has done something a bit unique to help address the problem. They have built what is called the world's first highway for bees in the capital city of Oslo. It's not typical highway like you'd picture in your mind, but rather a series of safe spots on rooftops that allow bees to move through the city.

Researchers double fiber optic capacity limit

Researchers double fiber optic capacity limit

Fiber optics offer incredibly fast data transfer speeds, but the logistics of setting up the actual fibers has stymied companies from rolling out the service. The further that data from fiber optic cables has to go, the less likely it is to be accurately interpreted by a receiver. This means that distance is a limiting factor in designing fiber optic transmission networks. Researchers from the University of California, San Diego, specializing in photonics, have uncovered a way to increase a the maximum power of optical signals travelling through optical fibers. By increasing the power, the distance is effectively increased, too. The researchers sent information over a record-breaking distance of 12,000 km without using any repeaters (electronic regenerators.)

Bouncing tactical camera lets police peer safely into dangerous rooms

Bouncing tactical camera lets police peer safely into dangerous rooms

First responders and law enforcement officers often encounter dangerous obstacles on the job. They can't see through walls, but a new bouncing camera can be thrown into a dangerous situation to give officers a clear understanding of where any hostages or gunmen are located.The "tactical spheres" house a six-lensed camera that can record surroundings and stitch them into a single photo which is then sent to a responding officer's smartphone. The ball is also equipped with temperatures and carbon monoxide sensors.

SpaceX CRS-7 mission explodes en-route to ISS

SpaceX CRS-7 mission explodes en-route to ISS

SpaceX's latest resupply mission to the International Space Station ended in failure today, as the CRS-7 mission rocket exploded shortly after take-off. An investigation is underway, with SpaceX founder Elon Musk suggesting that an issue in the upper stage liquid oxygen tank led to over-pressure. Two minutes and thirty-nine seconds after the Falcon rocket and its Dragon capsule blasted off from Space Launch Complex 40 at Cape Canaveral Air Force Station, observers were shocked to see it explode just before second-stage separation was due to take place.

NASA nears Ceres mystery spots: pyramid-like peak spotted

NASA nears Ceres mystery spots: pyramid-like peak spotted

The dwarf planet Ceres has presented quite the mystery: bright spots in a cluster. The spots were first spotted around the beginning of this year, and as the Dawn spacecraft grows nearer we've seen the spots become more clear. The latest shots show them from the closest distance yet, and among the other images is yet another mystery: a pyramid-like mountain sitting out on a barren landscape all by itself. This latest shot of the bright spots was taken on June 9.

Black hole has woken up after 26 years of dormancy

Black hole has woken up after 26 years of dormancy

According to data from NASA's Swift satellite, a huge black hole located about 7,800 light-years from Earth has re-awakened after 26 years of being dormant. The European Space Agency (ESA) describes the black hole as part of V404 Cygni, a binary system made of up the hole and a star. The last time activity was detected from V404 was in 1989, but as of June 15th, the Swift satellite is detecting new bursts of gamma rays.

Researchers turn small swarm of robots into Gauss gun able to penetrate tissues

Researchers turn small swarm of robots into Gauss gun able to penetrate tissues

Science is to the point today where we can build tiny nano machines that are capable of being injected into a human body. The challenge now is to make those tiny machines usable for treating different conditions inside the body. One way that researchers are controlling tiny robots inside the body is by using an MRI machine that allows the delivery of control signal to the machines and allows researchers to see what the robots are doing and where they are going.

SpaceX to try third attempt at rocket landing on Sunday

SpaceX to try third attempt at rocket landing on Sunday

SpaceX is one of the most successful private space flight companies in the world and has done very well with its Dragon capsule resupply missions to the ISS. One thing that SpaceX has been trying to perfect is the ability to land and reuse the first stage of the Falcon 9 rocket to help cut the costs of space flight. SpaceX notes that the rocket itself is most of the cost of space flight.
