A Japanese construction company says it might be possible to build a space elevator by 2050 using carbon nanotubes to form a cable 96,000 kilometers long. There's no way to estimate the cost for this gigantic elevator to space, though, since the materials to actually build it can't be manufactured (yet?). [url]

Ion propulsion systems have been under development for decades, and the Dawn spacecraft used an ion thruster to get a closer look at a big asteroid named Vesta. Ion thrusters can run for a long time, unlike chemical propulsion, and achieve velocities far greater than conventional rockets. [url]

Masten Space Systems' Xombie suborbital rocket had a successful test flight, demonstrating vertical takeoff and landing maneuvers for NASA. This rocket uses a flight control system that could help land spacecraft on asteroids or other non-terrestrial bodies. [url]

To discover more links on space exploration, check out what's floating around in StumbleUpon universe. [url]  

By the way, StumbleUpon can also recommend some good Techdirt articles, too.

Carbon nanotubes can form a rubbery material that stays rubbery over a really broad temperature range. It's not flubber, but it's still pretty cool. [url]

CementConcrete is a ubiquitous building material -- imagine if it also sequestered CO2. This isn't exactly a new idea, but it would be cool if it could actually scale. [url]

Titanium foam for replacing your bones doesn't sound as cool as Adamantium. Maybe titanium teeth will be the next trend for rappers, though. [url]

Don't mess with Pyrex! Soda lime glass just doesn't cut it like borosilicate. [url]
