asteroidsLow Power Milli-Newton Propulsion for Exploring Low Gravity Asteroids

No Comments
Exploration of small bodies, namely comets and asteroids remain a challenging endeavor due to their low gravity. The risk is so high that missions such as Hayabusa II and OSIRIS-REx will be performing touch and go missions to obtain samples. …

astronomyNeutrino Detector Sizes are Measured in Cubic Kilometers

No Comments
The IceCube Neutrino Observatory is a neutrino observatory constructed at the Amundsen–Scott South Pole Station in Antarctica. Its thousands of sensors are located under the Antarctic ice, distributed over a cubic kilometer. IceCube consists of spherical optical sensors called Digital …

astronomyChina’s Chang’e 4 Probe Takes 360 Panoramic Photo

No Comments
China’s Chang’e-4 probe took panoramic photos on the far side of the moon. The images were sent back via the relay satellite Queqiao, which was operating around the second Lagrangian point of the earth-moon system, about 455,000 km from the …

astronomyCanada’s Radio Telescope Has Ground Breaking Astronomy While Partially Operational

Canada’s radio telescope has detected the second repeating fast radio burst (FRB). FRBs are short bursts of radio waves coming from far outside our Milky Way galaxy. Scientists believe FRBs emanate from powerful astrophysical phenomena billions of light years away. …

astronomyBrightest Gravitationally Lensed Object Ever Seen is 600 Trillion Times Brighter than our Sun

No Comments
Astronomers have discovered the brightest gravitationally lensed object ever seen. They don’t expect to find many quasars brighter than that in the whole observable universe. The quasar is fueled by a supermassive black hole at the heart of a young …

astronomyModular Inflatable Composites for Giant Space Telescopes

No Comments
There is an every-growing need to construct large space telescopes and structures for observation of exo-planets, main-belt asteroids and NEOs. Space observation capabilities can significant enhanced by large-aperture structures. Structures extending to several meters in size could potentially revolutionize observation …
