NOAA is rolling out a new way for small satellites built by the commercial sector to hitch a ride on the upcoming advanced Joint Polar Satellite System-2 (JPSS-2) spacecraft launch and test their technology to determine if it will meet NOAA’s observation requirements.

NOAA looks to test the capabilities of these privately funded small satellites because a new NOAA Satellite Observing System Architecture study shows that future satellite instruments with lower cost and/or increased performance could provide significant benefit in NOAA’s future observing systems. On July 31 , NOAA published a Request for Information seeking demonstrations of key capabilities to enable realization of these benefits. The approved satellites will have the opportunity to fly as a “rideshare” on the JPSS-2 launch vehicle in one of several available slots on the JPSS-2 Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter (ESPA) ring.

“NOAA is providing small satellite vendors access to space through the JPSS-2 launch. This will give them a relatively low cost opportunity to demonstrate their capabilities,” said Karen St.Germain, Ph.D., director, NOAA’s Office of Systems Architecture and Advanced Planning.

She added: “NOAA will also benefit from access to the small satellite vendor’s observation data, which will provide an understanding of possible future capabilities and their potential benefits to NOAA’s mission.”

, the second in a series of next-generation polar-orbiting satellites following the successful launch of operational satellite NOAA-20 (also known as JPSS-1), is scheduled to launch in 2022. Issuing the RFI now gives the satellite community time to present their proposals and prepare for the launch should NOAA choose to pursue next steps based on RFI responses.

Earth-bound electronic games can’t compete with actually controlling a squadron of miniature robotic satellites in space. Through the Synchronized Position Hold, Engage, Reorient Experimental Satellites- Zero Robotics (SPHERES-Zero-Robotics) challenge, students compete to experience this power and excitement.

Using a trio of autonomous satellites on the International Space Station, SPHERES-Zero-Robotics gives students the chance to develop software to guide robots through a virtual obstacle course aboard the space station. High school students write algorithms for specific tasks for the volleyball-sized robotic satellites, and run them as virtual simulations on a computer and under realistic microgravity conditions in elimination rounds. Finalists have their programs sent to the station, where an astronaut loads them into the SPHERES satellites and monitors their movements to help determine a winning student team. The exciting final competition streams live at the European Space Agency (ESA) technology center in the Netherlands, European Space Research and Technology Center (ESTEC), and Massachusetts Institute of Technology.

The competition involves NASA, MIT, ESA and the Russian Space Agency (ROSCOSMOS). It is open to teams from high schools around the world. In the U.S., many states use the competition to introduce young people to the practical applications of science

, technology, engineering, and math (STEM).

The satellites have their own power, propulsion, computers and navigation, using 12 small thrusters to rotate and move around. They have been used inside the station since 2006 to test autonomous rendezvous and docking maneuvers and liquid slosh in microgravity.

The competition is about more than feeding the satellites sets of commands; local experts help students build critical engineering skills such as problem solving, design thought process, operations training and teamwork—all skills that could lead to the development of software to enable autonomous robots to accomplish complex tasks in the future. Their results could lead to important advances for satellite servicing and vehicle assembly in orbit.

“Zero Robotics aims to inspire the next generation of scientists and engineers,” said Jeff Hoffman, veteran NASA astronaut and SPHERES co-investigator with MIT. “We wanted to provide students with the chance to interact directly with NASA and space. This competition encourages them to develop their math and science skills as well as an appreciation for the physics involved in space engineering.” Alvar Saenz-Otero, the investigation’s primary investigator, founded the program at MIT.

The program helps teachers connect with students, said Shannon Bales, a STEM lead with the Alabama Afterschool Community Network, an initiative to promote positive development and learning when students are out of school. Bales said it is exciting for students to see the results of their hard work culminate with an astronaut running their programming live on the space station.

“It’s so rewarding for them and for us,” Bales said. “Last year, a parent told me their son really came out of his shell after Zero Robotics and how much he loved working on it. The program is making a difference in students’ lives and that’s why we do it.” The students have fun, exercise creativity, and learn valuable problem-solving skills, and feel like they are contributing to NASA research, she added.

The SPHERES-Zero-Robotics program provides students a unique and valuable opportunity to engage in space research and see the possibility of being a part of NASA’s mission to explore. No mere game can compete with that.

Weather forecasters officially have a new tool in their arsenal, as the first satellite in NOAA’s new Joint Polar Satellite System has passed rigorous testing and is now operational.  Launched last November as JPSS-1 and renamed NOAA-20 once it reached orbit, the satellite features the latest and best technology NOAA has ever flown in a polar orbit to capture more precise observations of the world’s atmosphere, land and waters. Data from the satellite’s advanced instruments will help improve the accuracy of 3-to-7 day forecasts.

“Improved weather forecasts can save lives, protect property and provide businesses and communities valuable additional time to prepare in advance of dangerous weather events,” said Secretary of Commerce Wilbur Ross.

NOAA-20 provides NOAA’s National Weather Service with global data for numerical weather prediction models used to develop timely and accurate U.S. weather forecasts. In addition , high-resolution imagery from the satellite’s Visible Infrared Imaging Radiometer Suite, known as VIIRS

, will enable the satellite to detect fog, sea-ice formation and breaking in the Arctic, volcanic eruptions and wildfires in their very early stages. This advanced modeling and imagery information, shared with international and governmental partners, will help businesses, the emergency preparedness and response communities and individuals make the best decisions possible in the face of weather-related hazards.

NOAA-20 joins Suomi NPP – the NOAA-NASA demonstration satellite launched in 2011 – giving the U.S. the benefit of two sophisticated spacecraft in nearly the same orbit. Each circles the Earth in a polar orbit 14 times a day, collecting global observations that form the basis for U.S. weather prediction.

“NOAA-20 is especially beneficial for tracking developing storms in the Arctic, Alaska and Antarctica. Forecasts for these remote regions are critical for the U.S. fishing, energy, transportation and recreation industries, which operate in some of the harshest conditions on the planet,” said Neil Jacobs, Ph.D., assistant secretary of commerce for environmental observation and prediction.

JPSS-2, the second in the series, is scheduled to be launched in 2021, followed by JPSS-3 in 2026 and JPSS-4 in 2031. JPSS satellites are designed to operate for seven years, with the potential for several more years. The JPSS mission will deliver its critical data and information for at least the next two decades to support a Weather-Ready Nation.

JeTSI team member, Patrick Barnes presented the poster, “Utilizing MBSE to Modularly Architect the NESDIS Ground Enterprise” at the American Meteorological Society’s 14th Annual Symposium on New Generation Operational Environmental Satellite Systems . The power of Model-Based Systems Engineering (MBSE) lies in the relationships built between the systems , activities, and functions within the model. Rather than a flat, two-dimensional view, MBSE allows for interweaving relationships in architecting a system of systems. The model can be updated to keep it current

This poster shows the JPSS ground system as a subset in the larger NOAA NESDIS ground architecture model. The NESDIS Ground System consists of segregated systems, operations, networks, and facilities. This amalgamation of systems and system of systems is often referred to as the NOAA “stovepipes.” With the transition of GOES-16 and JPSS-1 operations to NOAA, we will see an increase in the complexity of the overall NESDIS Ground System. The addition of hundreds of systems, servers, and network nodes make understanding the system as a whole a daunting task. Modern architecture tools and disciplines, such as Model-Based Systems Engineering, can be used to clearly define the as-is state of a ground system regardless of complexity.
