What To Eat When On Mars
As you know and we have mentioned in other issues, preparations are being made to bring a future trip to Mars closer to reality. One of the important parts of the planning and preparation is FOOD.
HI-SEAS (Hawai'i Space Exploration Analog and Simulation) is a 120-day Mars exploration analog study, run by researchers at Cornell and University of Hawaii with the goal to study and develop foods for astronauts on a mission to Mars.
The 120 -day period started in April and ended in mid-August. For the duration of the study, 6 people have been living in a space habitat on a lava field, a Mars-like environment on Mauna Loa. They have lived as if on Mars; going outside their habitat dressed in simulated spacesuits, conducting science experiments and consuming pre-prepared foods as well as making meals with ingredients that could withstand the duration of a Mars trip.

How High A Grasshopper Jumps!
In the past, we have been featuring advances in SpaceX Falcon and Dragon (newsletter issues 22, 44, 45, 49). Today we want to follow up with news of SpaceX Grasshopper.
On August 13th, aptly code-named Grasshopper, the Falcon 9 test rig, completed a divert test. During the test, not only it flew 250m high, but it also maneuvered 100m laterally before returning to the center of the launching pad.

Soon, a cell phone with dead batteries may not be as useless as we assume. A group of researchers at the University of Washington have come up with an interesting idea that enables devices to communicate with each other without needing batteries or wires. They are proposing to use the existing TV and WI-FI transmissions that surround us.
Their main idea is to harness these freely available wireless signals to power devices and then use the reflection of the same signals to create a communication channel between them. To prove their concept, they have already built prototypes the size of a credit card.
There would be many applications for this technique. For example, one can build sensors that are placed in important structures, such as bridges, to monitor the health of the structure.
