Observing The Skies Above By Kirby Wright On Flickr.

This morning, an Atlas V rocket launched from Cape Canaveral, Florida, carrying a US Navy communications satellite into space. 

It was another smooth take off for the United Launch Alliance, the company that manufactures the Atlas V. It was a particularly beautiful launch as well; the rocket left a spectacular multi-colored trail in its wake as it ascended into space

NASA’s MAVEN Discovers How Mars Lost Its Atmosphere

“The good news for us, mind you, is that the magnetic field here on Earth shows no sign of ceasing anytime soon. The dynamo in the core may do things like flip and reverse, swapping north-and-south magnetic poles, but we should continue to stay protected from the solar wind far into the foreseeable future: for billions of years (at least) to be sure. We could, conceivably, one day suffer the same fate as Mars, but our mass, our rotation and our active, dynamic core should keep the Earth’s magnetic field in business for at least as long as the Sun shines!”

If you had taken a trip to our Solar System four billion years ago, you would have found two worlds with liquid water oceans, temperate atmospheres and all the conditions we believe are needed for life. Earth would have been one of them, but Mars would have met all those criteria, too. It was long suspected that something happened to Mars around a billion years into the Solar System’s history that caused it to lose its atmosphere, something that should still be going on today. Thanks to NASA’s Maven mission, we’ve measured this atmospheric stripping by the Sun for the first time, and we’ve reached a few incredible conclusions, including that in about two billion years, Mars will be completely airless, and that if we were to terraform Mars today, it would hang onto this new atmosphere for millions of years.

Come get the full story of how Mars lost its atmosphere, and learn what NASA’s Maven mission has taught us so far!

San Francisco sours on rampant delivery robots: 'Not every innovation is great'

Lawmakers pass regulations to cut down on delivery robots as pedestrians tire of sharing sidewalks with ‘aggressively entrepreneurial wet dreams’

Will it be appropriate to tip “robot handlers,” as when they were “delivery people”? Or will the robots pool their tips, and give their handlers a small cut?

When the wrong yoghurt is delivered two hours late and left dripping in the rain, will it be the robot or the handler who gets fired?

Just askin’. 

NASA Tests 3-D Printed Engine Components

3-D printing isn’t just for toys and plastic models of your head. Witness a hot fire of NASA’s newest design for rocket engine injectors, 3-D printed to up performance in a way that traditional manufacturing of the parts couldn’t attain.

The agency, which tested the experimental injectors last month at Marshall Space Flight Center in Huntsville, Ala., used a type of 3-D printing called direct laser melting. To make the parts, a machine fires a laser at metal powder under the direction of a computer design program. This deposits layers of the metal one on top of the other until the part is complete.

NASA says the technique is letting engineers build the injector out of just two parts instead of the 163 formerly needed using traditional manufacturing methods.
