10 Questions For Our New Head Of Science

'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

best and also an intresting one:)

The First Irregular Moon Discovered on this Day!

On September 19, 1848, astronomers William Cranch Bond, George Phillips Bond and William Lassell discovered the first non-sperical, irregular moon orbiting the planet Saturn, which they named Hyperion (Ὑπερίων) after the Greek god/titan who was the brother of Cronus (the Greek equivalent of Saturn). Looking like a giant potato in the sky, Hyperion is the second largest non-sperical satellite discovered, measuring 360.2×266×205.4 km. Lassell and Bond both observed Hyperion independently of each other only days apart, and only a year after William Herschel had published Results of Astronomical Observations made at the Cape of Good Hope in which he suggested the name scheme for the first seven moons of Saturn, and which Lassell and Bond used when they proposed Hyperion.

6 Tiny Satellites That Are Changing How We See Earth

HARP: Hyper-Angular Rainbow Polarimeter

What’s better than taking a picture of a cloud to figure out its size and shape? Taking a bunch of pictures all around it. That way you get a three-dimensional view without having to worry about missing something. The HARP CubeSat is going to do just that: make observations of cloud droplets and tiny airborne particles like soot and dust with a modified camera lens from multiple angles. This will give us a full rendering of what’s going on inside the clouds, specifically, how those airborne particles act as “seeds” for water vapor to condense on and form cloud droplets. Since so many of those particles are in the air as a result of man-made pollution, we want to understand how they may be affecting clouds, weather and climate.

RAVAN: Radiometer Assessment using Vertically Aligned Nanotubes

Anyone who’s worn a black shirt on a summer day knows how much sunlight and heat it absorbs. The RAVAN 3-unit CubeSat, however, carries “blacker than black” technology – carbon nanotubes set up like a bundle of drinking straws that suck up nearly all the sunlight and energy that reach them to the point that your black shirt seems merely dark grey in comparison. Flying in low Earth orbit, RAVAN’s super sensitive instrument will detect tiny changes in the amount of sunlight and energy passing into and out of the top of the atmosphere. The amount of energy passing through the top of the atmosphere is where the net accounting of Earth’s energy budget happens – one of the major measurements we need in order to understand the effects of greenhouse gases on global warming and climate change. 

MiRaTA: Microwave Radiometer Technology Acceleration

That long skinny piece coming out of the bottom right side under the solar panel? That’s a measuring tape. It’s doubling as a communications antenna on the MiRaTA CubeSat that will be a mini-weather station in space. This 3-unit, shoe box-sized satellite is testing out new, miniaturized technology to measure temperature, water vapor, and cloud ice in the atmosphere. They’ll be tracking major storms, including hurricanes, as well as everyday weather. If this test flight is successful, the new, smaller technology will likely be incorporated into major – large – weather satellite missions in the future that are part of our national infrastructure.

IceCube

The aptly named IceCube will measure – you guessed it – ice in our atmosphere. Unlike the droplets that make up rain, ice is one of the harder things to measure from space. IceCube is a 3-unit CubeSat about the size of a loaf of bread outfitted with a new high-frequency microwave radiometer, an instrument that measures naturally occurring radiation emitted by stuff in the atmosphere – cloud droplets, rain, and the ice particles at the tops of clouds. This will be the first space test of the new microwave radiometer that has to balance its tiny size and low power with being sensitive enough to detect cloud ice. 

CYGNSS: Cyclone, Global Navigation Satellite System

What do GPS signals do when they’re not talking to your phone? A lot of them are just bouncing harmlessly off the planet’s surface – a fact that the CYGNSS mission is taking advantage of to measure wind speed over the ocean. Eight identical small satellites, each about the size of a microwave oven, flying in formation carry custom modified GPS receivers pointed at the oceans. When the water is smooth – not windy – the GPS signals reflect back uniformly, like the moon on a pond reflected as if in a mirror. When the water is choppy – windy – the signals reflect back in in the same direction but distorted, like the moon reflection on a choppy pond being distorted by ripples. Flying eight satellites in formation means the CYGNSS mission can measure wind speed across more of the ocean at once, which will help with understanding tropical storms and hurricanes. 

TROPICS: Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats

An important way to improve forecasts of hurricane and tropical cyclone intensity is to see what’s going on inside and around them while they’re happening. That’s the goal of the TROPICS mission, 12 CubeSats that will fly in formation to track the temperature and humidity of storm environments. The TROPICS CubeSats will get very frequent measurements, similar to X-rays, that cut through the overall cloud-cover so we can see the storm’s underlying structure. The storm structures known as the eyewall – tall clouds, wind and rain around the eye – and rainbands – the rainy parts of the spiral arms – give us clues about whether a storm is primed to intensify into a category 4 or 5 storm, something everyone in their path needs to know.

Cool man... It's just DAMN cool 😋😇.

In reference to never using the word ‘very’ when writing, Mark Twain said, “Substitute ‘damn’ every time you’re inclined to write ‘very’; Your editor will delete it and the writing will be just as it should be.” Source

Pirates didn’t make their captives walk the plank. Though big fans of torture methods like flogging and marooning, there are no actual records of pirates using a plank. The first mention of plank walking was in a 1724 fictional novel by author Daniel Defoe, but if real-life pirates wanted to drown someone, they probably just threw them off the boat. Source Source 2

Most of the time we don't realize 'precious moments' until it becomes a memory.

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
