Solar System: Things to Know This Week
There’s even more to Mars.
1. Batten Down the Hatches
Good news for future astronauts: scientists are closer to being able to predict when global dust storms will strike the Red Planet. The winds there don’t carry nearly the same force that was shown in the movie “The Martian,” but the dust lofted by storms can still wreak havoc on people and machines, as well as reduce available solar energy. Recent studies indicate a big storm may be brewing during the next few months.

2. Where No Rover Has Gone Before
Our Opportunity Mars rover will drive down an ancient gully that may have been carved by liquid water. Several spacecraft at Mars have observed such channels from a distance, but this will be the first up-close exploration. Opportunity will also, for the first time, enter the interior of Endeavour Crater, where it has worked for the last five years. All this is part of a two-year extended mission that began Oct. 1, the latest in a series of extensions going back to the end of Opportunity’s prime mission in April 2004. Opportunity landed on Mars in January of that year, on a mission planned to last 90 Martian days (92.4 Earth days). More than 12 Earth years later, it’s still rolling.

3. An Uphill Climb
Opportunity isn’t the only NASA Mars rover getting a mission extension. On the other side of the planet, the Curiosity rover is driving and collecting samples amid some of the most scenic landscapes ever visited on Mars. Curiosity’s two-year mission extension also began Oct. 1. It’s driving toward uphill destinations, including a ridge capped with material rich in the iron-oxide mineral hematite, about a mile-and-a-half (two-and-a-half kilometers) ahead. Beyond that, there’s an exposure of clay-rich bedrock. These are key exploration sites on lower Mount Sharp, which is a layered, Mount-Rainier-size mound where Curiosity is investigating evidence of ancient, water-rich environments that contrast with the harsh, dry conditions on the surface of Mars today.

4. Keep a Sharp Lookout
Meanwhile, the Mars Reconnaissance Orbiter continues its watch on the Red Planet from above. The mission team has just released a massive new collection of super-high-resolution images of the Martian surface.

5. 20/20 Vision for the 2020 Rover
In the year 2020, Opportunity and Curiosity will be joined by a new mobile laboratory on Mars. In the past week, we tested new “eyes” for that mission. The Mars 2020 rover’s Lander Vision System helped guide the rocket to a precise landing at a predesignated target. The system can direct the craft toward a safe landing at its primary target site or divert touchdown toward better terrain if there are hazards in the approaching target area.

That's a good nature living idea ; green idea😇
An Indian company created shopping bags that are 100% natural, biodegradable, and edible. It took 4 years to develop the bags, which are made of potato, tapioca, corn, starches, and vegetable oils. Though slightly more expensive than plastic, the bags break down quickly, dissolve completely, and become a safe food source for animals rather than a choking hazard. Source
Why Do We Study Ice?
Discover why we study ice and how this research benefits Earth.
We fly our DC-8 aircraft very low over Antarctica as part of Operation IceBridge – a mission that’s conducting the largest-ever airborne survey of Earth’s polar ice.
Records show that 2015 was the warmest year on record, and this heat affects the Arctic and Antarctica – areas that serve as a kind of air conditioner for Earth and hold an enormous of water.
IceBridge flies over both Greenland and Antarctica to measure how the ice in these areas is changing, in part because of rising average global temperatures.
IceBridge’s data has shown that most of Antarctica’s ice loss is occurring in the western region. All that melting ice flows into the ocean, contributing to sea level rise.
IceBridge has been flying the same routes since the mission began in 2009. Data from the flights help scientists better measure year-to-year changes.
IceBridge carries the most sophisticated snow and ice instruments ever flown. Its main instrument is called the Airborne Topographic Mapper, or ATM.The ATM laser measure changes in the height of the ice surface by measuring the time it takes for laser light to bounce off the ice and return to the plane – ultimately mapping ice in great detail, like in this image of Antarctica’s Crane Glacier.
For the sake of the laser, IceBridge planes have to fly very low over the surface of snow and ice, sometimes as low as 1,000 feet above the ground. For comparison, commercial flights usually stay around 30,000 feet! Two pilots and a flight enginner manage the many details involved in each 10- to 12-hour flight.
One of the scientific radars that fly aboard IceBridge helped the British Antarctic Survey create this view of what Antarctica would look like without any ice.
IceBridge also studies gravity using a very sensitive instrument that can measure minuscule gravitational changes, allowing scientists to map the ocean cavities underneath the ice edges of Antarctica. This data is essential for understanding how the ice and the ocean interact. The instrument’s detectors are very sensitive to cold, so we bundle it up to keep it warm!
Though the ice sheet of Antarctica is two miles thick in places, the ice still “flows” – faster in some places and slower in others. IceBridge data helps us track how much glaciers change from year-to-year.
Why do we call this mission IceBridge? It is bridging the gap between our Ice, Cloud and Land Elevation Satellite, or ICESat – which gathered data from 2003 to 2009 – and ICESat-2, which will launch in 2018.

Japanese are working on developing technology to transmit electricity wirelessly. Their goal is to transmit energy from orbiting solar panels to Earth by 2030. They have successfully transmitted 10 kW of energy 500 meters away.

'Make a green change' series posts
Yo there, I’m releasing a new series post which is being post on to F-taser. Let’s get to the point, yeah I’m talking about how we all together can make a simple green change.everyday we already have two to three hours of free time, of you everyday consume only just twenty minutes for this ‘go green’ projects, we could make a very great difference and we could relax a lot with this green environment. Yes you could really feel a great difference.while breathing this plant-purified air you could get that green energy. In the following post will post some how-to projects to go green… Bye. And happy Christmas everyone
