The facts of the (anti)matter

3 Comments

Antimatter has powered countless science fictional starships, but has yet to be used as a propulsion method in reality. Reasons are manifold: firstly, it’s very difficult and expensive to make even the tiniest amount of it; and second, we’re still not entirely sure what it is or how it works. Centauri Dreams reports on the state of antimatter research, and hopes that someday we’ll be able to use it to move between the stars.

That said, successful Space Shuttle launches aside, we’re still short of a simple and affordable route to orbit, let alone our nearest stellar neighbours. JP Aerospace reckons it has an answer to getting us at least half-way there – namely making lighter-than-air flyers to ascend to a sub-orbital space station, from which super-light orbiters could be launched. It’s a low-budget lo-fi approach, but if it works, why not?

Space is the place for a resource-rich and peaceful existence

astronauts in orbit over earthI think I’m largely preaching to the choir when I plug the benefits of space exploration here at Futurismic, but I’m not going to let that stop me. And we’re not alone in our beliefs – the former President of India says that the vast energy resources that space technologies can exploit make the price of admission well worthwhile.

Meanwhile over at Space.com, Al Globus explains how space colonisation is a viable alternative to war (here’s a hint – resources again), and points out that repurposing the military budgets of the world into space habitats would make the necessary budgets look tiny. I agree with him entirely, but I doubt he’ll have much luck convincing the hawkish types who make decisions of that kind. Still, fingers crossed. [Image from NASA]

NASA manager opposed to Bush’s lunar plans

The moonSome dissent in the ranks at NASA; the man who led the development of the Apollo lunar module has come out in vocal opposition to plans to use explorations of the Moon as a test-bed for eventual manned missions to Mars; instead, he argues for full exploitation of the ISS and further robotic missions to the Red Planet.

Arguments of this type are ten a penny in space politics, which is a landscape of conflicting ideologies; Moon versus Mars, robotic missions versus human missions, and so on. An essay at The Space Review argues that these conflicts are “zero-sum games”, and a waste of energy and resources that could be better expended by the different groups working together toward common goals. Human nature being fundamentally factional, I’m not going to hold my breath just yet. [Image by jurvetson]

A dark day for the space industry

3 Comments

NASA hasn’t had a good year for PR so far. Following on from the embarrassing media circus over the exploits of an ex-astronaut earlier this year, now they’re having to go public with the news that not only were some astronauts drunk in charge of their launch vehicles, but that they also discovered an act of sabotage on a computer module destined for the ISS.

Even the private sector hasn’t escaped the black cloud; an explosion at the test facility of Burt Rutan’s Scaled Composites, the company that is to supply Virgin Galactic with its sub-orbital vehicles, has killed three and injured as many again.

Stories like the above make me think that, as much as good as they look on paper, we probably shouldn’t be building nuclear powered rockets just yet – the cost of mistakes and mismanagement could be far higher.
