NASA teleconference on sea level change warns of rising oceans

By - August 27, 2015 4 Pictures

On Aug. 26, NASA held a media teleconference regarding current predictions on sea level rise, highlighting the risks to coastal populations in low-lying areas, and the inherent problems in creating reliable global models. A panel of experts from NASA's recently-founded Sea Level Change Team tells us that ocean levels are inexorably on the rise, but gaps in our understanding and ability to survey risk regions mean we don't know just how fast the change will take place.

Construction of next-gen hurricane-hunting satellites begins

By - August 21, 2015 2 Pictures

What is small enough to fit in an airliner carry-on bin and has the potential to save thousands of lives and millions of dollars worth of property? The answer is the Cyclone Global Navigation Satellite System (CYGNSS) – NASA’s next-generation hurricane-observing microsatellites, which are now being assembled at the Southwest Research Institute (SwRI) in San Antonio, Texas.

Scramjet-based project looks to blast Australia into space

By - August 9, 2015

The list of spacefaring nations remains small, but thanks to continuing advances in technology that promise to reduce the financial and logistical hurdles involved, the numbers are set to increase. One country that could be joining the club, if the University of Queensland (UQ) and Heliaq Advanced Engineering get their way, is Australia. The two are teaming up on a project intended to deliver payloads weighing from 50 to 500 kg (110 to 1,102 lb) into orbit.

Quantum satellite reconfigures itself in orbit

By - July 11, 2015 2 Pictures

In the early days of spaceflight, every new satellite was a one off. Today, satellites are produced in classes, but each new mission still needs a satellite that's individually configured for its role. With the goal of creating a next-generation universal satellite, ESA, Eutelsat, and Airbus Defence & Space have signed an agreement to develop the first fully reconfigurable Quantum satellite.

UK consortium proposes mission to provide five-day warning of solar storms

By - July 8, 2015 3 Pictures
Solar storms – or Coronal mass ejections (CMEs) – are caused by the sudden release of built-up magnetic stress in the Sun's atmosphere. On Earth, we see the results of small versions of these when plasma streaming from the sun strikes our upper atmosphere and creates the Northern and Southern Lights (the Aurora Borealis and the Aurora Australis). Sometimes, however, these ruptures can be inordinately large and have the potential to wreak havoc on orbiting satellites, radio networks, and national power grids. In an effort to be prepared well in advance of such events, a UK consortium has proposed a satellite system that can provide as much as five days warning of potentially damaging CMEs. Read More

EPFL's CleanSpace One satellite will "eat" space junk

By - July 7, 2015 4 Pictures

Three years ago, Swiss research institute EPFL announced its plans to build a spacecraft that could grab orbital debris and then carry it back towards Earth, burning up in the atmosphere with it on its way down. Called CleanSpace One, the satellite was depicted at the time as using a claw-like grasping tool. Now, however, EPFL has announced that it will utilize a folding conical net to essentially gobble up bits of space garbage.

ESA's mission to de-clutter low-Earth orbit takes a step forward

By - June 5, 2015

ESA's mission to mitigate the environmental impacts on low-Earth orbit from mankind's relentless march into space has entered a new phase, ahead of its make-or-break review before the ESA's Council of Ministers in December 2016. The e.Deorbit program would launch multiple debris-seeking probes into orbit each year, tasked with the removal of defunct satellites and other potentially hazardous man-made objects from low-Earth orbit.
