It seems as if the age of the bench-top breakthrough in rocket science is not a thing of the past. Dr Patrick Neumann of the University of Sydney has developed a new ion drive as part of his PhD thesis that is claimed to outperform the best one devised by NASA. According to Neumann, his new drive, which is still in the experimental stage, is more efficient than the latest High Power Electric Propulsion (HiPEP) ion engine and holds the promise of "Mars and back on a tank of fuel."
Murchison Widefield Array (MWA) radio telescope in the Western Australia
desert, a Sydney University student, Cleo Loi, has discovered enormous plasma pipes in the Earth’s upper atmosphere. Thought to be responsible
for possible radio interference with satellite navigation systems, the presence of these objects has been predicted for over 60 years, but never before seen. By imaginatively using the radio telescope to observe
in 3D, Loi was able to image large areas of the
sky using the fast photography capabilities of the MWA to produce a movie
that shows the motions of the plasma in real-time.
