NASA Tests First Deep-Space Internet

NASA - Friday, 30 October 2009
nasa_deep_space_internetPASADENA, Calif. -- NASA has successfully tested the first deep space communications network modeled on the Internet.

Working as part of a NASA-wide team, engineers from NASA's Jet Propulsion Laboratory in Pasadena, Calif., used software called Disruption-Tolerant Networking, or DTN, to transmit dozens of space images to and from a NASA science spacecraft located about more than 32 million kilometers (20 million miles) from Earth.

"Did you get stung the other day?" a biology graduate student asks as he pulls on a white coverall over his jeans.

"Sure did," says Michael Goodisman. "That thing hit me in the ankle, it hurt like crazy!"

Learning the secrets of the birds and the bees, and the wasps can be a hazardous pursuit. Georgia Institute of Technology biology professor Michael Goodisman, along with two of his graduate students, are suiting-up, willing to take it on the ankle and wherever else the aggressive yellow jackets may sting.

Cloud Computing Defined

Cloud Computing DefinedCloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.

An Overview of Computer Diagnostics

An Overview of Computer DiagnosticsDiagnosing your computer can help to identify any problem or failure that your PC shows when it's having problems. Diagnostics are used to test the computer system, which includes both the BIOS and memory, software, and even the hardware that is installed on the computer.

Dedicated Servers: Some Things to Consider

Dedicated Servers: Some Things to ConsiderIf you have been checking out dedicated servers online, you have probably noticed that there are many different choices.  You can choose from budget dedicated servers or dedicated servers that have more bandwidth.  The type of dedicated server that you choose depends upon the following:

Ten Steps To Green Computing and Green I.T.

The push for green IT is becoming a big wave among businesses in the US and anywhere else in the world. More and more business owners are becoming aware of the need to implement IT infrastructures that are guaranteed to be "green."

Keeping Your Car Clean And Green

The effects of global warming is felt in many parts of the world, and unless drastic measures are made to reduce carbon emissions, we might find ourselves opening our doors to the dawn of a new Ice Age. Of all sources of carbon emissions, the automobile industry has the largest contribution.

Ancient Astronauts and Contemporary Skepticism

Over the course of the past year, I closely assisted a colleague in writing a series of ten articles covering diverse aspects of my ancient astronaut theory. All ten of those articles circulated widely around the globe and view counters on many sites indicated plentiful readership, but feedback to me, or to her, from anywhere, was non-existent.

Teaching Space and the Solar System

 Outer space and the solar system is one of the most interesting topics discussed in school because of the countless colorful heavenly bodies occupying the universe and the idea that there is actually something else outside of our world.
