Traditional propulsion systems are highly inefficient when it comes to space travel, mostly because they have to carry fuel on board, thus after covering a fair amount of distance, spacecrafts often find themselves drifting helplessly through the immensity of space. The effect can be clearly observed even with satell... |

The Solar Dynamics Observatory is expected to become the next space device to monitor solar flares, sunspots and coronal mass ejections in order to make accurate predictions on solar weather. Recently the Solar Dynamics Observatory, or SDO for short, was lowered and attached to the propulsion module that will help it... |

After being lifted up into space with the help of the Ariane 5 space rocket, the Jules Verne Automated Transfer Vehicle detached itself from the launch vehicle and started its race towards the International Space Station. However, what was called by the European Space Agency a flawless launch proved to be anything bu... |

The Janus particle name is given to any microscopic sphere which is composed of two halves that are chemically or physically different. North Carolina State University researchers have demonstrated that while being submerged into a liquid excited by an alternating electrical field, Janus particles start to behave lik... |

When it comes to technological breakthroughs in the nanoworld, it seems nature has still a lot to teach us. Squids, octopuses and jellyfish swim by creating jets of water which push the animal forward based on the principle that every action has an equal and opposite reaction.This is pretty much what a group of rese... |

Many aircraft, ships or submarines use fluids, like water or air for propulsion, by using propellers to push the fluid backward, which generates forward motion. The propeller is usually attached to the crankshaft of the engine, either directly or through a gearbox. A new theoretical blueprint aims to replicate this ... |

Nanotechnology and the study of very small robots that could one day do a lot of good has been one important aspect for a number of researchers and the applications in which these robots could be used are many. A similar process has begun in the computer industry with the introduction of smaller and yet smaller compo... |
