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.
Space is cold, but not cold enough for satellite sensors that need to be kept at cryogenic temperatures. Lockheed Martin’s lightweight High Power Microcryocooler is designed to keep these vital components cold, and it now packs three times the power density of previous systems.
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.
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.
NASA's Deep Space Climate Observatory (DSCOVR) has returned a breathtaking image of planet Earth from a distance of roughly one million miles from the homeworld. The image captures the full disk of our planet showing a stunning sunbathed vista of blue oceans and swirling clouds, with glimpses of the North and Central America land masses.
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.
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.
PlanetiQ has begun testing its new Pyxis weather instrument. Pyxis tracks GPS signals traveling through the atmosphere and makes measurements based on their behavior. PlanetiQ says it can "dramatically improve weather forecasting, climate monitoring and space weather prediction."
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.
