The satellite, ICESat-2, which has a 91-day orbit, is the size of a Smart car and will send lasers back down to Earth countless times in order to give scientists a precise measurement—down to within a centimeter—of the planet’s polar ice sheets and how they’re changing, according to the agency.
Scientists will be able to examine how the ice is responding to changes in the atmosphere and the ocean, giving them a picture over time of what is making the ice melt or not in certain areas.
Once they gather this data about the thickness of sea ice and the height of ice sheets, it will inform their future models to better predict potential sea level rise scenarios, NASA says.
“As the climate is warming, we are seeing changes in the sea level—sea level is rising,” Helen Fricker, a professor of glaciology at the Scripps Institution of Oceanography who worked with NASA on the ICESat-2 project, told WBUR. “But the ultimate thing that we're trying to get to is, how much ice will we lose and how quickly will we lose it?”
According to NASA, melting ice in Greenland and Antarctica has increased the global sea level more than a millimeter per year, which is a third of the overall increase.
ICESat-2, which launched on Sept. 15, is capable of providing much more comprehensive coverage of ice loss across the world.
“In the time it takes someone to blink, sort of half a second, ICESat-2 is going to collect 5,000 measurements in each of its six beams, and it’s going to do that every hour, every day … it’s a tremendous amount of data,” Tom Neumann, NASA’s deputy project scientist, told the Guardian.
According to Fricker, the first data from ICESat-2 will start coming back by mid-October.
“It's going to be all hands on deck for several months while we work out what these data are telling us, and we really wait. It's incredibly exciting,” she said.

Markle, 37, was attending her first solo outing since becoming the Duchess of Sussex when she was seen closing the car door on her own. The Duchess was dressed to the nines in a black dress by Givenchy that goes for $3,300 paired with a matching clutch worth $1,990. The outfit was finished with a pair of diamond earrings that go for $12,000, Page Six reported.
Some social media users praised the Duchess for closing the door while others joked she may have cost someone their job.
“A princess who still takes the time to shut her car door. Well done Meghan!” The Sun’s royal corresponded Emily Andrews tweeted.
“Everyone is freaking out because Meghan Markle closed her own door…Good thing she has arms and is able to close the door!!!!! Plus she is totally used to doing that, is probably even a reflex! I say is totally cool that she closed her door!!!” a social media user tweeted.
William Hanson, an etiquette and protocol coach, tweeted that the door close was not a protocol breach.
“This is not a protocol breach,” he wrote. “Usually royalty and dignitaries have someone to open/close car doors for security reasons: nothing to do with ‘princess behavior.’ Meghan clearly just shut the door out of force of habit.”
Despite the hoopla, the newly minted royal has closed her own door before. Last week, at an event to launch a cookbook aimed at raising money for the victims of London’s Grenfell Tower fire, Markle was seen closing a vehicle door behind her.

Rebels in the Northwestern province of Idlib are making their last stand against government forces backed by heavy Russian airstrikes. And as they brace for the next government offensive, both the rebels and civilians in the area are looking to a new app to help give them an early warning when airstrikes are incoming. The carnage has forced innovation before. Civilians, at first, used walkie-talkies to warn of warplanes. Rescue teams developed more sophisticated ways to liberate families from the rubble. In hospitals, doctors developed workarounds for when lights go out and drugs run dry.  And then in 2016, a team of computer developers found a way to link all those efforts.
It's called "Sentry" - a smartphone and computer application that acts as an alert system, using data from both human observers and report sensors. John Jaeger, one of the co-creators, calls it a ground-breaking app that could signal a breakthrough in early-warning detection systems by using "crowdsourcing" as its main data points. "These observations are of aircraft in flight and they include facts like what kind of airplane, which direction it is heading, and then of course things like time of day and where the observation was made." Jaeger added that the system "then makes a determination of where and when that aircraft might go. This determination creates a warning for the local populace and potentially affected communities, and that warning goes out over popular social media platforms."
It's fairly simple to use. When users see a military aircraft, they enter the data into three designated fields. The data is then processed by the app, which creates a list of possible targets based on estimates of the plane's trajectory - triggering warning messages on social media, and air raid sirens in towns and cities throughout the area.  Dave Levin, another co-founder, says the company is "doing a lot of outreach to try to get as many people aware of the program and understanding how to use the app and particularly outreach to women."
Levin and Jaeger are both Americans with experience in Mideast conflicts. Jaeger is a former State Department employee, and he's used his experience and contacts to get funding for the project from countries including Great Britain, Canada, the Netherlands and the United States, as well as private donors. He says the goal, in addition to saving lives, was to help empower the Syrian people to help themselves.]]> 2018-10-02 11:16:01 UTC https://padlet.com/louisebillon0708/kqigh8fnl0zp/wish/288039935 eva_canals https://padlet.com/louisebillon0708/kqigh8fnl0zp/wish/289038275

I'm very sorry to hear about your loss, I know it mustn't be an easy time for you.
Don't worry, Cloé can do her News Review tomorrow as indicated in my Guidelines. We can work something out for you at a later date. 

Best regards,
