A new analysis of pebble-containing slabs investigated by NASA’s Curiosity rover confirms a stream once ran through Gale Crater on Mars.
During a pit stop last year, Curiosity came upon hundreds of smooth, round pebbles that look strikingly similar to deposits in river banks on Earth.

‘Most people are familiar with rounded river pebbles. Seeing something so familiar on another world is exciting.’

– Rebecca Williams of the Planetary Science Institute 

Scientists believe the rover rolled onto an ancient streambed, but needed to study the stones in more detail. So Curiosity snapped high-resolution pictures and fired its laser at several pebbles to analyze the chemical makeup.

Researchers say the roundness of the stones was shaped by a fast-flowing stream that probably was ankle to waist-deep. Curiosity landed in the crater near the equator last summer.

Rebecca Williams of the Planetary Science Institute, the lead author of the new report, said that researchers were able to determine the depth and speed of the water that once flowed at the site.

“These conglomerates look amazingly like streambed deposits on Earth,” Williams said. “Most people are familiar with rounded river pebbles. Maybe you’ve picked up a smoothed, round rock to skip across the water. Seeing something so familiar on another world is exciting and also gratifying.”

Sanjeev Gupta, a co-author of the report, said that analysis of the amount of rounding on the pebbles indicates that the stream was flowing at a sustained, vigorous speed.

“The rounding indicates sustained flow. It occurs as pebbles hit each other multiple times. This wasn’t a one-off flow. It was sustained, certainly more than weeks or months, though we can’t say exactly how long,” Gupta said.

The stream carried the gravel at least a few miles, the researchers estimated.

The analysis appears in Friday’s issue of the journal Science.

The Associated Press contributed to this report.

Writer Prompt for Flash Fiction – Death by Bunnies!

If you want to do something fun, your writing prompt is “death by bunnies” and the picture below.  Not playboy bunnies guys, not the dread monster bunny of Monty Python’s Holy Grail – no, just bunnies.  Submit them to eiverness@cox.net and I will put together an unqualified panel to select ones to re-post here.  Let’s have some fun.  1,000 words or less, as a picture is worth 1,000 words, so it is said, so let it be… (Lets give you a week to send one or more in, so the due date is June 8, 2013. )

It started out as a simple feeding and descended into the dark recesses of unimagined horrors.

Next-generation flying car

Terrafugia unveils next-generation flying car

It’s a flying car!
At least more than the last one was.

Terrafugia, creators of the Transition street-legal airplane, have unveiled their vision for the next generation of personal aircraft, the TF-X.

The TF-X is closer to being a direct replacement for the automobile than the Transition, which features retractable wings that allow it to be driven on public roads and is primarily intended for use as a conventional aircraft that takes off and lands from an airport runway.

It’s also a hybrid, in more ways than one.

Although it flies like a fixed-wing aircraft, the four-seat TF-X was designed to take off and land vertically with the help of collapsible, electrically-powered rotors mounted on the ends of its fold-up wings. They draw their energy from a battery pack of yet-to-be-determined size and chemistry that can either be charged via an electrical outlet, or by the gas turbine engine that powers a rear-mounted propeller when the TF-X is in flight.

On the ground, the TF-X is propelled by electric motors in the wheels that are also run off of the battery pack, or in series hybrid mode where the turbine generates electricity after the battery charge is depleted.

A pilot’s license will still be required to fly the TF-X, but Terrafugia says a five-hour training session is all it will take to learn how to operate the vehicle. However, the idea is that you won’t have to do much of the flying at all.

Thanks to the FAA’s NextGen program, which will require all aircraft to be equipped with satellite transponders sending their exact location to a centralized air traffic management system starting in 2020, the TF-X could be able to fly entirely by itself from takeoff to landing. The pilot will still be ultimately responsible for the operation of the vehicle, and can fly it manually, but shouldn’t need to do more than enter a destination into a navigation system, sit back and enjoy the ride.

A 500-mile range is planned along with a top speed of 200 mph, and a built-in parachute will bring it safely to the ground in the event of any major mechanical failures along the way.

But don’t plan to impress the neighbors by lifting off from your driveway just yet. Terrafugia says the powerful prop wash of the TF-X will require a clear 100-foot diameter zone for takeoffs and landings, which will likely need to be regulated like helicopter pads are today. Terrafugia envisions more of these being established by cities and towns with the advent of vehicles like the TF-X.

They’ll have plenty of time to sort it out. Terrafugia figures it’ll be 8 to 10 years before the TF-X makes it from the drawing board to the skies, and even the Transition is still a couple of years away from entering production. The company is aiming to start delivering the $279,000 vehicles in early 2015.
