The James Webb Space Telescope Prepares to Peer Past Hubble

For two decades, the Earth-orbiting Hubble Space Telescope helped pierce the veil of time, image stellar nurseries and prove that galaxies collide. Now, the James Webb Space Telescope stands poised to take those observations to the next level, making the delicate observations possible only in the cold, dark spaces beyond the moon.

Slated for a 2018 launch date and team-built by 14 countries, 27 states and the District of Columbia, Webb will take astronomers closer to the beginning of time than ever before, granting glimpses of sights long hypothesized but never seen, from the birth of galaxies to light from the very first stars. Join us as we explore…

Mars in a Nutshell

Leave a comment
Think you know everything about Mars. eh?

We live in a golden age of Mars exploration, an era of unprecedented knowledge brought to us by ingenious rovers and probes. Already we have learned that our diminutive neighbor once held water and perhaps life. Future missions will help determine where that water went and seek evidence deep beneath the surface of living creatures. One day, we might even go there ourselves. But how much have you kept up on the latest developments?

To Catch a Comet

For a spacecraft to overtake a comet, let alone touch down and ride it sunward, requires trick-shot billiards on an astronomical scale. But that’s exactly what the ESA/NASA International Rosetta Mission to comet 67P/Churyumov-Gerasimenko is doing. Launched a decade ago aboard an Ariane 5 rocket, its loop-the-loop, gravity-slingshotting journey has juiced its speed enough to overtake the comet, which can reach speeds of up to 83,885 mph (135,000 kph), and set it up to land in November 2014. Which raises the question…

How do you land a spaceship on a comet?

Hypersonic: Don’t believe the hype

Imagine a Mach-20 aircraft capable of flying coast to coast in less time than it takes a passenger to clear security; now imagine the jet lag to follow. If the idea still sounds appealing, bear in mind that the most recent attempt at such a plane flew right out of its own skin before ditching into the Pacific.

Welcome to the world of hypersonic flight.

Of course, that was a military weapons platform; contrary to what some aircraft manufacturers’ flacks would have us believe, passenger planes are likely to remain subsonic or supersonic for the foreseeable future – and for good reason.

Rocket imageLike international waters, space is a commons usable by all but owned by none; but, unlike any earthly commons, space borders every country on the planet, and actual or metaphorical fallout from an incident there could spoil days — or destroy lives — anywhere on Earth.

So, who watches the spacemen? And what laws or treaties exist to protect us all? The answers might surprise you.
