Max's Cool Beans – So Much to Do, So Little Time... PDF Print E-mail

I don’t know about you, but my days are full to bursting with "stuff" to do. In the last couple of weeks as I pen these words, for example, I've presented to the folks at NASA and the Jet Propulsion Laboratory (JPL) and been involved in an on-stage debate at the Embedded Systems Conference (ESC) in Silicon Valley.

Let's start with my JPL presentation (I'll waffle on about ESC in a future column). I've been interested in spaceflight since I was a little lad, so I was very excited when the folks at JPL invited me to fly out to Pasadena, California, to talk to them about the state-of-the-art in FPGA technologies, including devices and design and verification tools.

As soon as I'd been checked in through security at JPL (which was about five minutes before I somehow managed to lose my security badge), the first thing I say was a picture of myself plastered on a video screen accompanying an announcement of my talk. (My mother will "dine out" at her hairdressers for weeks on this.)

Truth to tell, I was a wee bit nervous about giving this talk because the folks at JPL are all super-clever and you always worry that you are going to make a bosh of the whole thing. In the event, however, my presentation seemed to go down rather well, and it's spawned some interesting projects that I will relate in a future column.

Following my talk, the folks at the JPL were kind enough to give me a guided tour and I got to see all sorts of mega-cool things, such as the laboratory in which they are assembling and testing the next-generation Mars Rover.

Compared to previous rovers, this one is going to be a monster (about the size of a small car). This means that they can't land it the way they did the previous rovers (surrounding them in balloons and bouncing them along the surface of Mars until they come to a halt). So they showed me a simulation of the solution they've decided upon.

The idea is that everything is packed in a large capsule that hurls in through the atmosphere. Once things have slowed down sufficiently, the heat shield is dumped and a parachute is deployed. This is where things start to get really interesting. As the capsule nears the ground the parachute is discarded and a rocket system fires up. The rocket flies around until it decides on the best landing location, and then the rover is lowered to the ground on cables with the rocket still firing. Once the rover is on the ground, the cables disengage and the rocket flies off and lands itself somewhere close by.

I cannot convey to you just how cool this all is. When the new Rover eventually gets to Mars, I will be watching the landing with bated breath and I will be remembering all of the preparations I saw at the JPL. Until next time, have a good one!

Printed circuit boards for most recent EPE constructional projects are available from the the online store. These are fabricated in glass fi bre, and are fully drilled and roller tinned. Double-sided boards are NOT plated through hole and will require ‘vias’ and some components soldering to both sides.

PCB masters for boards published from the March ’06 issue onwards can also be downloaded from the ‘Library’.

All software programs for EPE Projects previously published can be downloaded free from the Library on our website, accessible via our
home page.
