NASA to Track Earth's Ice Melt
Satellite with Most Advanced Laser Altimeter to Track Global Ice Melt
In mid-September, NASA will launch ICESAT-2. It's a $1 billion satellite loaded with the most advanced laser system NASA has ever launched into space. The purpose is to track and precisely document how the earth's ice sheets, sea ice and glaciers are melting. NASA officials think more than 2/3rds of the earth's ice has melted since the 1980's.
ICESAT-2 is going to provide an unprecedented level of detail and precision on how ice sheets' heights and thickness are changing. It's a 3 year mission and the highly advanced laser onboard adds the 3rd dimension to the measuring. The system is so precise it can document increases and decreases in ice thickness as small as 1/5 of an inch.
NASA says this instrument is "revolutionary" to study both land and sea ice. The laser beam splits into 6 beams and fires 10,000 pulses per second. The system will orbit 300 miles above the earth. The laser beams will bounce off the ice surface and photons will make their way back to the satellite providing data. Everything about this mission is precisely timed to detect measurement changes.
Forecasts on Sea Level and Climate Change
NASA officials believe this detailed study of change in sea ice, ice sheets and glaciers will help forecast the impact of the ice melt on sea levels and climate beyond the poles. In a 1/2 second, it will collect 5000 elevation measurements in each of its 6 beams. That data's coming 24/7 for the next 3 years. ICESAT- 2 has enough fuel to orbit for up to 10 years.
Robot, Cut My Lawn Source: Husqvarna Mowers Robo Mowers Powered by Batteries - No Gas It's at the top of my robotic wish list. A robot lawn mower. No astronomical bills and upselling from lawn service companies. Just a nicely cut lawn and no hassles. Innovation seems to be knocking at the front door with news on robotic mowers. Green Robots at the Cutting Edge There's a slew of new robot mowers. Models include Worx Landroid for smaller lawns, Honda that cuts and feeds lawns, Robomow for all-purpose mowing and Husqvarna that's loaded with cell & GPS tech. These mowers aren't cheap. Prices range from $1000 to $3500. They're powered by rechargeable batteries so they're quiet. You pay more for online enhancements. And, if your lawn is loaded with trees and hills, your robot mower is going to be a lot more expensive. Grass Vacuums Robot mowers look a lot like big robot vacuums such as iRobot's Roomba. They roam and groom your lawn. Their

New Invention: Tablet Toothpaste "Change Toothpaste" Source: Change Toothpaste Potentially Cuts 900 Million Plastic Toothpaste Tube Throwaways Per Year Tubes of toothpaste aren't something you think about but their impact on the global environment is hugely negative. 900 million toothpaste tubes are discarded into oceans and landfills globally every year. Importantly, it takes 500 years for them to breakdown, which means virtually every toothpaste tube created is still discarded someplace in the world. And, the tubes, which contain multiple layers of plastic, polymers and resins, can't be recycled. A company headquartered in Edmonton, Alberta Canada just came up with a solution in the form of tablet toothpaste. "Paste with No Waste" Entrepreneurs Mike Medicoff and Damien Vince are the inventors and founders of CHANGE Toothpaste. Their tablet toothpaste is an all natural vegan substance that works just like toothpaste but has no harsh chemic
