CHAT LIVE with NOAA Scientists about the Launch of JPSS-1!
October 2, 2017
NOAA's JPSS-1 satellite, the first of the new JPSS satellite constellation, will rocket into space on November 10, 2017. Don't miss the chance to chat live with two NOAA scientists and learn more about the satellite, its mission, the launch and the science behind it all!
Join our Reddit Science AMA on Thursday, October 12, 2017, from 1:00 pm - 3:00 pm Eastern and "ask these experts anything!"
For years, Dr. Mitch Goldberg, JPSS Chief Program Scientist, and Thomas Wrublewski, NOAA Physical Scientist, have been working with their Joint Polar Satellite System (JPSS) colleagues to prepare this next-generation polar-orbiting satellite for its trip into space. Now, the big day is almost here!
JPSS-1, or NOAA-20 as it will be known once it reaches orbit, will provide sophisticated meteorological data and observations of atmosphere, ocean and land. NOAA’s National Weather Service (NWS) will use JPSS data as critical input for numerical forecast models, providing the basis for three- to seven-day forecasts.
According to the NWS, 85% of the data flowing into our weather forecast models come from polar-orbiting satellites, such as Suomi NPP and, soon, the new JPSS series. Polar satellite data also provides emergency personnel with more accurate forecasts, allowing them to pre-position equipment and resources days before a storm. JPSS will continue to serve this vital role.
You can learn more about the JPSS-1 satellite series and see the countdown to launch on our website.

NOAA’s JPSS-1 Satellite Arrives in California for Launch
September 5, 2017
NOAA's Joint Polar Satellite System-1 (JPSS-1) satellite arrived at Vandenberg Air Force Base in California on Sept. 1, 2017, to begin preparations for a November launch.
After its arrival, the JPSS-1 spacecraft was pulled from its shipping container, and is being prepared for encapsulation on top of the rocket that will take it to its polar orbit at an altitude of 512 miles (824 km) above Earth.
JPSS-1 is scheduled to be launched aboard a United Launch Alliance Delta II rocket from Space Launch Complex-2 at Vandenberg Air Force Base in California on Nov. 10, 2017, at 1:47 a.m., PST.
JPSS-1, which will be known as NOAA-20 after it reaches orbit, has a seven-year design life. NOAA partnered with NASA to implement the JPSS series of U.S. civilian polar-orbiting environmental remote sensing satellites and sensors. JPSS-1 is the first in a series of NOAA’s four next-generation, polar-orbiting weather satellites.
Launched in 2011, the joint NOAA/NASA Suomi National Polar-orbiting Partnership (Suomi NPP), is a bridge between NASA's Earth Observing System of satellites and JPSS. Suomi NPP has been operating as NOAA’s primary operational satellite for global weather observations since May 2014.
JPSS-1 will orbit in the same plane as Suomi NPP, with JPSS-1 operating about 50 minutes ahead of Suomi NPP, allowing important overlap in observational coverage. It takes about 14 passes for each satellite in this orbit to cover Earth's surface.
The sensor capabilities for JPSS-1 have similar capabilities to those on Suomi NPP: the Advanced Technology Microwave Sounder (ATMS), built by Northrop Grumman; theCross-track Infrared Sounder (CrIS), built by Harris; the Ozone Mapping and Profiler Suite-Nadir (OMPS-N), built by Ball Aerospace; the Clouds and the Earth's Radiant Energy System (CERES), built by Northrop Grumman; and the Visible Infrared Imaging Radiometer Suite (VIIRS), built by Raytheon.
JPSS fulfills NOAA’s requirements to collect global multi-spectral radiometry and other specialized meteorological and oceanographic data, by remote sensing of land, sea and the atmosphere. These data support NOAA’s abilities to continuously observe Earth’s environment to better understand and predict changes in weather, climate, oceans and coasts, which supports the Nation’s economy and protect lives and property.

JPSS-1 Has New Target Launch Date
September 1, 2017
The launch of JPSS-1, the first in a series of NOAA’s four next-generation operational polar-orbiting weather satellites that will give scientists the most advanced tools to aid in weather forecasting and earth observations, is scheduled for November 10 at 1:47 a.m. PST from Vandenberg Air Force Base in California.
“Hurricane Harvey is a stark reminder of the importance of the NOAA satellite program,” said Secretary of Commerce Wilbur Ross. “Our thoughts and prayers go out to the families affected by this disaster.”
These advanced Joint Polar Satellite System (JPSS) satellites will serve as the backbone of NOAA’s weather forecasting system for the next 20 years, providing the reliable, global observations required to support accurate numerical weather forecasts up to seven days in advance.
The new launch date has given engineers extra time to complete testing of the spacecraft and instrument electronics and to finish work on the Advanced Technology Microwave Sounder, one of the primary instruments on JPSS. The satellite carries five state-of-the-art instruments providing a comprehensive suite of earth observations.
“The JPSS-1 team has done an incredible job getting this extremely capable satellite prepared for launch and ready to send back quality environmental data soon after it is in orbit,” said Stephen Volz, Ph.D., director, NOAA’s Satellite and Information Service.
The satellite is scheduled to arrive in California just before the Labor Day weekend, where it will undergo final preparation before it is launched aboard a United Launch Alliance Delta II rocket. When it reaches orbit, JPSS-1 will be renamed NOAA-20.
Following launch, JPSS-1 will join Suomi NPP, the joint NOAA-NASA weather satellite giving the United States two, highly sophisticated satellites, each circling the Earth 14 times per day, providing full, global observations for U.S. weather prediction. Suomi NPP, which initially was planned as a research and risk reduction mission when it launched on October 28, 2011, became NOAA’s primary operational satellite for global weather observations on May 1, 2014.
Ball Aerospace designed and built the JPSS-1 satellite bus and Ozone Mapping and Profiler Suite instrument, integrated all five of the spacecraft’s instruments and performed satellite-level testing and launch support. Raytheon Corporation built the Visible Infrared Imaging Radiometer Suite and built the common ground system. Harris Corporation built the Cross-track Infrared Sounder. Northrop Grumman Aerospace Systems built the Advanced Technology Microwave Sounder and the Clouds and the Earth's Radiant Energy System instrument.
NOAA works in partnership with NASA on all JPSS missions, ensuring a continuous series of global weather data to secure a more "Weather-Ready” Nation.

JPSS Proving Ground and Risk Reduction Teams Bridges the Gap between Data and Users
June 16, 2017
Smoke from the Fort McMurray fire was swept up into a cyclonic spin over northern Canada.
The process of transforming raw satellite data into useful products is complex and continuously under improvement. Leading this effort for NOAA's Joint Polar Satellite Service (JPSS), is the JPSS Proving Ground and Risk Reduction (PGRR) team -- a group comprised of JPSS scientists and engineers, as well as representatives from user communities, such as the National Weather Service (NWS) Weather Forecasting Offices and the National Ocean Services.
Each year, PGRR team members come together to hear from the scientists developing the latest Suomi NPP and JPSS data sets, algorithms and products, and get feedback from users. This year, the PGRR team held its 2017 PGRR Project Review in late May at the University of Maryland. The multi-day event included presentations from scientists working in the focus areas of hydrology, river ice and flooding, the arctic, oceans and coasts, fires and smoke; evaluations from end-users; and application-oriented focus groups that developed methodologies for implementing agreed-upon changes.
Based on the content of this year's review, it was clear that the PGRR program developed several successful products to help NWS and other users to leverage the capabilities of the instruments on board JPSS satellites and the data they produce to support key areas including weather, fires and flooding. Among them are:
Keeping Tabs on Alaska's Icy Rivers
River ice is a significant threat in Alaska where ice can dam and flood a river quickly. PGRR products are used to track ice and flooding conditions in this area and proved valuable in helping residents respond to a flooding event on the Yukon River in May 2013 and have been in use during Alaskan Spring ice break-up ever since.
Tracking Wildfire Smoke in the Atmosphere
The Fire and Smoke Initiative described how JPSS scientists were able to build on their success evaluating products during the Fort McMurray fire in Alberta, Canada in May 2016. VIIRS Day/Night Band imagery showed the fire's progression on consecutive nights and the team used its visualization products to show how smoke from the fire moved in the atmosphere.
Monitoring Marine Health with Sea Surface Temperature
The National Ocean Service and the National Marine Fisheries Service used Ocean and coastal products from JPSS pertaining to ocean color, nighttime maps, and sea surface temperature, which is a critical measurement for coral reefs, in long and short-term efforts to conserve marine ecosystems.
