California launch of new U.S. weather satellite postponed

California launch of new U.S. weather satellite postponed

According to the National Weather Service, 85% of the data flowing into their weather forecast models come from polar-orbiting satellites like the one that will launch Tuesday. "After it successfully clears the on-orbit test phase, NOAA-20 will become the nation's primary polar weather satellite and Suomi NPP will become its back up". "JPSS will continue this trend", he added.

Maue said that without data from polar satellites, "weather forecasts would noticeably suffer leading to more forecast busts, wayward hurricane tracks and more difficulty in preparing for severe weather". As Mitch Goldberg, the chief program scientist for JPSS at NASA told Space.com, meteorological catastrophes like hurricanes tend to originate far away from the places they affect. JPSS-1 will allow researchers to monitor changes in the atmosphere in Africa that could cause a hurricane off the coast of Florida, for example.

The five next-generation instruments on JPSS will be a major upgrade from NOAA's legacy polar-orbiting satellites.

Several instruments aboard the satellite will provide detailed observations of temperature, air moisture, ice, snow, fog, wildfires, precipitation and ozone around the world. The series of four JPSS satellites are expected to span 20 years.

Drinking A Lot Has Been Linked to Cancer, Doctors Warn
However, ASCO is not asking people to forgo drinking completely; they are only suggesting a controlled consumption of alcohol. Their findings show just 38 per cent of people are limiting their alcohol intake to reduce their risk of cancer.

A Delta II rocket launch that was scheduled for early Tuesday morning from Vandenberg Air Force Base was scrubbed at the last minute and postponed for at least 24 hours.

Northrop Grumman Corporation (NYSE:NOC) will build and deliver the Advanced Technology Microwave Sounder (ATMS) for the Joint Polar Satellite Systems (JPSS) under a contract with NASA. Shortly after the postponement was revealed, Omar Baez Jr., a NASA senior launch director, confirmed that the plan was to retry the launch again at 1:47 a.m. Wednesday. But a bad reading on the first stage of satellite's United Launch Alliance Delta II rocket, as well as boats in the safety zone, forced NASA to call off the launch just minutes before liftoff.

Polar satellites like the JPSS-1, which orbit the globe from pole-to-pole 14 times a day, are considered the backbone of the global observing system.
