KinetX Aerospace Navigates MESSENGER through Final Mission Phase

Simi Valley CA (SPX) May 03, 2015

KinetX Aerospace, the first commercial company to navigate any spacecraft to distant planetary bodies, announced that it has successfully guided the MESSENGER spacecraft through its final and perhaps most challenging mission phase. MESSENGER, a NASA spacecraft built and operated by the Johns Hopkins University Applied Physics Laboratory (APL), was launched in August 2004 and has been in orbit ar —> Read More

Hawaii Says ‘Aloha’ to NASA’s Low-Density Supersonic Decelerator

Kauai HI (SPX) May 03, 2015

The second test vehicle for NASA’s Low-Density Supersonic Decelerator project arrived April 25 at the U.S. Navy’s Pacific Missile Range Facility in Kauai, Hawaii. The vehicle now will undergo final assembly and weeks of testing prior to its scheduled experimental flight set for early June. The flight will test two cutting-edge technologies for braking Mars spacecraft.

Autonomous convergence and divergence of self-powered soft liquid metals

Beijing, China (SPX) Apr 30, 2015

The autonomous locomotion for a macroscopic machine remains an intriguing issue for the researchers to explore. Recently, Professor LIU Jing and his group from Tsinghua University demonstrated that as a versatile material, the liquid metal could be self-actuated when fueled with aluminum (Al) flake, and the motion thus enabled would persist for more than an hour at a quite high velocity.

In South Africa, Where Elephants Are Fenced In, Choosing Contraception Over Culling

The elephants take off running as the helicopter banks around a hill, pushing headlong through the bush and low trees into the river valley in South Africa’s Ithala Game Reserve.

The elephants seem to be fleeing the chopper’s noisy approach as if it’s some kind of predatory beast, but, the pilot says, “They’re not really panicking—they’re quite relaxed.” It’s just reflexive running, not true terror.

As the chopper circles, they group and regroup. Some raise their trunks and wheel. It’s hard not to imagine that the price of this aerial view—of a breeding herd of mothers and daughters and pre-adolescent sons and calves hurtling along the valley floor—is their fear.

The helicopter is giving a photographer ammunition for an article about an elephant contraceptive called PZP, which provokes an immune reaction in cows, causing them to produce antibodies that bind to the surfaces of their eggs and prevent fertilization.

A previous flight that morning had carried no one more dangerous than a veterinarian vaccinating elephant cows with the drug: green splotches of dye on their hindquarters marking where the darts hit.
