NASA's flying saucers hopefully won't be a smash hit

Marketplace - American Public Media - Wed, 2014-06-11 01:00

NASA may, weather permitting, launch what’s playfully being called a flying saucer.

It does look like a flying saucer, but it’s really more like landing gear...for Mars. NASA has ambitious plans for what it wants to send to the Red Planet – like people, habitats, and rockets for return journeys back to earth. This would involve payloads of 20, 30, or perhaps even 40 tons – dwarfing the one ton Curiosity Rover that touched down on Mars two years ago.

To land said gigantic saucers on Mars – which, by the way, travel at four times the speed of sound (Mach 4, 3,044 miles per hour, or 0.8 miles per second) -- you need to slow them down first.

“It’s difficult to land things on Mars versus Earth because the atmosphere is very thin, just one percent of Earth’s,” explains Mark Adler, program manager for the Low-Density Supersonic Decelerator (LDSD) project.

Parachutes alone won’t do, and rockets would require more fuel than anyone would like to carry all the way to Mars. “So we need large decelerators, to slow things down.”

That's where the “flying saucer” comes in. It’s a disc shaped payload that has, among other things, two experimental technologies to slow down vastly massive payloads.

The first is a “supersonic inflatable aerodynamic decelerator”: a doughnut shaped airbag that will make the payload a little more fat and less dense, slowing it down from four times the speed of sound to a mere two times the speed of sound.

The second is a large 100-foot supersonic parachute.

Together, they will be taken up to 120,000 feet by helium balloon, and then launched up to 180,000 feet where the atmosphere resembles that of Mars, reaching Mach 4.

Keith Cowing, editor of NASAWatch, says the technology is “probably one of the most cost-effective things one can imagine,” compared to using rockets to brake a rocket’s fall.

Cost effective doesn’t mean cheap, of course. This program costs $200 million dollars, of which $150 million has already been spent. It's one of the reasons NASA can't privatize the project like it does with cargo flights to the space station.

“You know, landing on Mars so far doesn’t seem to be very profitable,” says Michael Lopez Alegria, president of the Commercial Space Flight Federation. While he foresees a day when private companies will take up the slack, governments will have to open the frontier to Mars.

For now, that means not crashing into the surface of Mars at 3,000 miles per hour.

How (constantly) informed must we be?

Marketplace - American Public Media - Wed, 2014-06-11 00:23

First of all, mad props to my colleague David Brancaccio for starting – and finishing – the 544-mile AIDS/Lifecycle ride this past week. 

Second of all, more and bigger mad props for having the guts to put a picture of himself in full biking kit – spandex shorts, shirt, the whole deal – on his most recent post about the ride. I once did a photo shoot for Runners World magazine in the Marketplace studios, and let's just say, I'm still hearing about it.

This is not, however, a gratuitous post about Marketplace hosts in fitness gear. It's about the point David made more eloquently than I could, so I'm just going to piggyback on it here and add some observations. It's important, he wrote, to unplug every now and then. To consciously unplug. And to take the time you get back to just... be.

Believe me when I tell you I'm not preaching at you here. I'm as guilty as the next guy of burying my nose in my phone; of tuning out my kid's tennis match to check my Twitter feed (Yes, I'm that dad). Part of it is my personality, part of it is my line of work, and part of it is habit. 

But seriously – how many different variations of the Hillary Clinton book-tour interview do we need to read to know she's running for president (Yes, there, I said it. Come talk to me in a year, we'll see who's right)? How many times do you have to click on a link about Donald Sterling and whether he will or won't sell the Clippers – I mean, fercryinoutloud – to know he's an unsavory individual? And don't even get me started on the damn missing plane.

Yes, there is real news out there every day. And yes we do have an obligation as citizens in a representative democracy to be informed. But c'mon. Just... be.

Okay, now I'm preaching. So that's it. That's all I got this week. That, and don't ever, ever wear a short suit. As in shorts, but in a suit.
