To consider how lucky the Phoenix lander is, consider that a dozen Mars missions have failed on launch and a dozen (shown here) have failed after. Some say that Mars missions are cursed, by the reasons tend to be more mundane, such as the infamous Mars Climate orbiter failure which was due to a mistake using imperial rather than metric measures in software.

Apple’s refresh of the Macbook line this fall is more evolutionary than revolutionary. In terms of design they have continued the trend, which started with the iPhone (see the drilled headphone jack hole on the original model) towards machining directly from block metal. This has lead to the latest Macbooks as being described as having monocoque structures, something which may not strictly be false but which is meaningless in the context.A monocoque is a single piece shell structure, it is a nice sounding word and is often used in marketing literature because it sounds technical. Because of this, and because of the fact that things like commercial airliners are hybrids of frame and shell structures almost anything can be described as such. There is a perfect geodesic truss in the list below which is described as a monocoque shell structure (the opposite), while an ordinary soda can is a monocoque. The use of machining for Apple parts has more to do with tolerances and finish and almost nothing to do with structure, so the term is not relevant.Below we discuss the merits of things which are described as monocoque – but as for the Macbook, not really

If you have a hi-fi a TV, cellphone, computer and digital camera you already own several sets of speakers, amplifiers, microphones, screens and cameras. The idea of modular gadgets appeals on multiple levels, from Zen minimalism to the joy of playing with Legos.Here are some of our favorites.

The history of the pressure suit from its origins in the 30s for high altitude pilots to space missions is one which perfectly encapsulates (no pun intended) all of the aspects of product design from craft to science. Aesthetically, the first pressure suit, created by the aviator Wiley Post in 1934, looks more like a deep sea diving one, just as deep sea diving inspired the fictional aesthetic for robots and space men, until the space race. But the Post suit is where the two design styles diverge, culminating in the Apollo mission suits which were produced in craft fashion by the seamstresses of bra manufacturer, Playtex after their proposal outperformed those submitted by engineering contractors.Pressure suits don’t need to be air tight, apart from the helmet, because human skin is, they just need to be tight to stop your skin swelling. Those worn by pilots are usually different from astronauts, who also have to wear external layers of reflective insulation (separated by intermediate layers of non heat conducting material, exactly like modern loft insulation) and a protective skin against micro-meteors and abrasive dust. As well as all fabric pressure suits, there are rigid or partially rigid ones, such as some of the moon walk prototypes or space walk (EVA) ones which are hybrids of a rigid torso and flexible limbs. EVA and moon walk suits have a life support system as a backpack, while astronauts often carry theirs like a suitcase, as a backup in case cabin pressure fails.

I started this list as a Thanksgiving homage to American innovation via its greatest inventor. Reading more about Edison and his strange obsession with things like filming electrocutions, using alternating current, of everything from small animals to people and even an elephant, just to try and put people off the rival AC system, managed to put me off him. So as an act of revenge here are some of his less successful, stranger inventions from concrete phonographs to what became the tattoo machine and a ghost detection instrument. Happy Thanksgiving anyway.
