We feel for engineers who have to build budget machines. After all, with a limited component budget, do you splash out on a long battery or a better keyboard? Toshiba’s Satellite U845 was designed to navigate those pitfalls, doing “just enough” to combine a reasonable battery life with decent performance and unspectacular build quality. The results is a dependable and solid device for a cash-strapped back to school type, but was it the one for you? Did you think that Toshiba made the right calls here? Welcome to How Would You Change, where you get to lob suggestions over the company’s garden wall and see if they listen.

While Toshiba already outed its Haswell plans, the company has chosen today to unveil a few more PCs. The outfit’s refreshing its Satellite U and M range in the UK, with the U50t being equipped with a 10-point touchscreen and Windows 8 onboard. The Satellite M50D and M50Dt, meanwhile, boast AMD’s latest APU processors and Radeon graphics. The whole line (which is slated for dispatch in Q3) ships with Intel’s fourth-generation processors and HD 4400 graphics, while those needing a bit more oomph on the pixel pushing side can opt for NVIDIA’s GeForce GT 740M. As you’d expect, Intel’s WiDi and Miracast technologies are infused, and each machine arrives with a full-size HDMI port, Bluetooth 4.0, an SD card slot and a pair of USB 3.0 sockets. Tosh isn’t talking pricing just yet, but you can dig into the specification list just after break.

Plants grown and sustain themselves through photosynthesis—a seemingly invisible process that converts sunlight into energy. Now, NASA scientists have developed a way to measure photosynthesis from satellites with unprecedented detail.

There might not be a man on the moon right now—but there may soon be a gazing eye. A new private venture aims to build a long-range telescope on our planet’s little satellite, and it could happen as soon 2016.

It might look like a colorful oil painting, but you’re actually looking at an Envisat radar image of chain of volcanoes called the Virunga Mountains—home to Africa’s two most active volcanoes.

Many stunning objects in our solar system have tails. We see them most often in comets, meteoroids, asteroids, etc. Tails are formed when dust and ice on these objects burn up as they heat up, which results in debris letting loose and leaving a trail behind the comet. As it turns out, even our own solar system has a tail.
NASA has discovered that our entire solar system consisting of Earth and other planets has its own tail that stretches 93 billion miles long. You may have not given it any thought really, but our solar system is also flying through the universe just like a comet would, leaving behind its own trail of space dust and ice.
NASA’s Interstellar Boundary Explorer (IBEX) is currently out in space and mapping the edges of the solar system. Specifically, it has recently mapped the boundaries of the tail of the heliosphere, which is something that has never been possible before. Scientists have long assumed that the solar system has a tail, but we’ve never been able to see until now.
It’s officially called a “heliotail,” and it’s made up of both slow and fast-moving particles that were released by the sun. These particles escape the magnetic field surrounding the solar system and are invisible to the naked eye by the time they reach the edge of this magnetic field, but luckily, NASA is able to map them out with IBEX.
Scientists, astronomers, and researchers are still determining exactly how long the tail is, since 93 billion miles is simply just a rough estimate, but it seems that NASA has most of the details confirmed, and the study was published today in The Astrophysical Journal.

A few years from now, we might be able to send small satellites into deep space for cheap using a new propulsion system being developed by University of Michigan engineers — assuming they raise enough money via Kickstarter. Called CAT (CubeSat Ambipolar Thruster), it’s designed to propel 10 x 10 x 10 centimeter CubeSat blocks far beyond the planet’s orbit using only solar energy for fuel. Thus far, similar satellites can only orbit the Earth after going along for a ride on current rockets that are larger and more expensive. In the future, CATs could head to the asteroid belt, or even as far as Saturn and Jupiter to investigate water on their moons. The $200,000 its engineers aim to raise (in exchange for your name etched on the golden layer of a spacecraft panel) will go towards the CAT engine’s development and testing. The team could send an experimental thruster to space as soon as 2014 with help from NASA-Ames and Google, with a spacecraft launch targeted for 2015.

Last night, India successfully sent the satellite IRNSS-1A into space on one of its own rockets, making it the first of seven that will provide the country with a GPS-like navigation system. The rocket – called the Polar Satellite Launch Vehicle-C22 – was sent into space from the Satish Dhawan Space Center a little before

India will soon have a positioning system of its own. Much like our own GPS, the Indian Regional Navigation Satellite System (IRNSS) is scheduled to provide location information to civilians and government users alike, with a position accuracy of 20 meters or better. Seven satellites will make up IRNSS, including three in geostationary orbit and four in inclined geosynchronous orbit, which will rotate with the Earth. GPS currently covers the Indian subcontinent, as it does the rest of the world — like GLONASS in Russia and BeiDou in China, IRNSS will provide additional utility to users within 1,500 kilometers of the Indian mainland. It’s expected to come online by 2016.
