Spire expands contract with NASA for EO data

Spire Global, Inc. (NYSE: SPIR) reports the continuation of its participation in NASA's Commercial Smallsat Data Acquisition (CSDA) Program with a new contract extension.

The award is in support of NASA's SigNals of Opportunity: P-band Investigation, or SNOOPI mission. The Purdue University and NASA team, led by Professor James Garrison, will launch a satellite into low Earth orbit (LEO) to detect and analyze P-band radio signals for the purpose of measuring root-zone soil moisture on Earth.

As part of the mission, Spire performed a custom collection of ultra high frequency (UHF) and P-band data for the SNOOPI team. The lower frequency of P-band signals allows the radio emissions to penetrate farther into the soil than L-band signals, enabling the team to obtain measurements deeper below the surface when compared to modern L-band remote-sensing techniques employed by NASA's Cyclone Global Navigation Satellite System (CYGNSS).

"The SNOOPI mission is the first demonstration of measuring root-zone soil moisture from space using signals of opportunity that are important for detecting early drought warnings as well as crop-yield forecasts," said Kamal Arafeh, Senior Vice President of Global Sales, Spire.

"We are honored to work with NASA and other government agencies worldwide to show how scientific innovations using space-based data can help humanity measure, adapt to, and mitigate the impacts of climate change."

"Spire's UHF collection, which we believe to be the first ever collection of reflected P-band signals in orbit, enabled the SNOOPI team to reduce risk and check our basic working principles prior to our launch," said Jeffrey Piepmeier, Chief Microwave Instrument Engineer, NASA's Goddard Space Flight Center.

"Working with Purdue University, we continue to advance the signals of opportunity technique, which we hope leads to the first satellite remote sensing of root-zone soil moisture, which is the water contained in the top meter of the soil where it is absorbed by plants, a very important variable for applications such as agricultural production forecasting and flood prediction."

Through the CSDA Program, NASA has integrated Spire data into its research and applications portfolio by using space-based data to investigate water and sea ice levels in the polar regions, estimate the height of the Planetary Boundary Layer (PBL), and discern daily variability of thermospheric density at satellite flight level.

NASA also noted that Spire data has shown positive benefit to its GEOS Atmospheric Data Assimilation System, which uses space-based data to analyze the Earth's atmosphere by assimilating the data into its Earth modeling and analysis system. As one of the original vendors for the CSDA Program, Spire provides NASA yearly updates to the scope of work under this agreement to ensure alignment of data to the agency's needs.

SNOOPI is led by Purdue University for NASA's Earth Science Technology Office and implemented by NASA's Goddard Space Flight Center with instrument hardware and technology validation contributions from NASA's Jet Propulsion Laboratory.

Taking the dazzle out of CryoSat yields a first
Paris (ESA) Sep 15, 2022
Since it was launched more than 12 years ago, ESA's CryoSat ice mission has dazzled by way of its sheer technological and scientific excellence. This superb Earth Explorer satellite has returned a wealth of information that has transformed our understanding of Earth's ice and how it is responding to climate change. In some circumstances, however, being dazzled isn't a good thing, particularly when it comes to measuring the height of sea ice from space during the summer. A paper published in Nature ... read more
