Resilient Space Internet Comes Down to Earth Gadgets with Android

A new Internet protocol designed for interplanetary transmissions is bringing its delay-tolerant magic to Earth

Google's Android does a lot more these days than just smart phones and nifty mobile gadgets. An Internet pioneer is using the platform to launch a interplanetary Internet protocol on Earth that could harden wireless networks against delays in data transmission.

Mutant Bacteria Are Likely to Threaten Future Space Travelers


When humans eventually travel to Mars and beyond, they'll have plenty to worry about along with the discomforts of eating freeze-dried food and drinking their own urine. A new report says they will probably be really sick, to boot -- from flare-ups of E. coli, chicken pox or staph infections.

A host of microscopic stowaways could make interplanetary voyagers sick, especially because human immune systems are compromised in space, and because bacteria seem to thrive in micro- or zero-gravity environments.

Digital TV Switch A Boon For Astronomers

The brief period of radio silence during the switchover makes it possible to listen for pulsars and other space entities that are otherwise drowned out

While most of the world looked forward to the switch from analog to digital TV for the sharper picture and clearer sound, astronomers around the US anticipated the changeover period for a totally different reason: clarity. In the brief period between the removal of analog television signals and the assignment of those frequencies to other devices like cell phones, astronomers will get their first look at a time in the universe that has been obscured from telescopes since Wally and the Beav roamed the airwaves.

First proposed in 1895, and popularized by the Arthur C. Clarke book The Fountains of Paradise, space elevators have a rich history in the culture of space travel. Unfortunately, the history of their engineering success is far less impressive. But if the results from this week's Space Elevator Games are any indication, that might be about to change.

Wearable Artificial Intelligence Could Help Astronauts Troll Mars for Signs of Life


Not since RoboCop has being a cyborg seemed so very cool. University of Chicago geoscientists are developing an artificial intelligence system that future Mars explorers could incorporate into their spacesuits to help them recognize signs of life on Mars' barren surface.

Space Hotel Reportedly On Track for 2012 Opening, Already Has Paying Guests

A company aiming to open the first space hotel already has 43 paying customers at $4.4 million a pop

Anyone with a cool $4 million and change might consider doing what 43 other people have done, and sign up for an orbital space vacation in 2012 with Galactic Suite Space Resort. The Barcelona-based company plans to open the first space hotel if all goes according to plan.

Remembering a Former Caltech Rocket Scientist and the Founder of China's Space Program

Qian Xuesen has died at 98; he helped found Caltech's Jet Propulsion Laboratory before being deported as a suspected Communist

One can only imagine how history might have played out if the United States had not deported a Chinese-born Caltech rocket scientist on suspicion of being a Communist in 1955. Qian Xuesen first fought his deportation, but later accepted his fate and went on to become the founder of China's missile and space programs. His death this past Sunday comes as China broadens its space exploration efforts to become a potential challenger to a troubled U.S. space program, or perhaps a partner.

The First Martian Weatherman Forecasts Conditions on the Red Planet


While much of the scientific community ponders the possibility of life on Mars, Atmospheric Sciences Professor Istvan Szunyogh of Texas A&M University is more concerned with finding out if there is "weather." While the Red Planet's thin atmosphere (only 1 percent the density or ours) means there isn't weather as we experience it here, we do know that there are clouds, extreme temperatures, strong winds and dust storms that make the worst on Earth look tame by comparison. As such, NASA has awarded a grant to Szunyogh and a team of other researchers to analyze and forecast those conditions.

As Space Collision Threat Looms, Pentagon Upgrades Its Monitoring of Satellites

The U.S. Air Force has upgraded its ability to predict possible satellite collisions, as the risk from space debris increases

Satellites currently must dodge an ever-growing gauntlet of other satellites and clouds of space debris, and this year the Pentagon has quietly upgraded its surveillance accordingly. The U.S. military announced yesterday that it now tracks 800 maneuverable satellites, compared to less than 100 prior to a February collision between an active U.S. satellite and a retired Russian communications satellite.

Why Astrophotography Is Worth the Trouble

(And the at-times-disappointing results)

Mixed Results: My first attempt at Jupiter [left] demonstrates why it's a tricky first target--the brightness of the planet against the darkness of space casts a wide dynamic range for the novice to capture. But it's possible, as a photo taken with the same camera provided by the SBIG folks shows [right].  Eric Adams/SBIG
Astrophotography is hard. Astronomically hard. Everything has to be perfect. Your telescope, with camera attached, must track your target in precise synchronization with the rotation of the Earth. It can't shake. It can't even vibrate. You have to nail your camera's exposure settings or you'll be rewarded with an incoherent mess. Your targets are often so dim you can't even see them until after the image has been made, so focusing is a nightmare.

So why try? Because it makes the entities floating in the vastness of the universe much more real than any Hubble wallpaper on your computer desktop can.
