2 Min Read NASA Seeks Commercial Feedback on Space Communication Solutions

Credits: NASA / Morgan Johnson NASA is seeking information from U.S. and international companies about Earth proximity relay communication and navigation capabilities as the agency aims to use private industry satellite communications services for emerging agency science missions.
“As part of NASA’s Communications Services Project, the agency is working with private industry to solve challenges for future exploration,” said Kevin Coggins, deputy associate administrator of NASA’s SCaN Program. “Through this effort, NASA missions will have a greater ability to command spacecraft, resolve issues in flight, and bring home more data and scientific discoveries collected across the solar system.”
In November 2024, NASA announced the TDRS (Tracking and Data Relay Satellite) system, the agency’s network of satellites relaying communications from the International Space Station, ground controls on Earth, and spacecraft, will support only existing missions.
NASA, as one of many customers, will obtain commercial satellite services rather than owning and operating a replacement for the existing satellite system. As NASA transitions to commercial relay services, the agency will leverage commercial capabilities to ensure support for future missions and stimulate private investment into the Earth proximity region. Commercial service offerings could become available to NASA missions as early as 2028 and will continue to be demonstrated and validated through 2031.
NASA’s SCaN issued a Request for Information on May 30. Responses are due by 5 p.m. EDT on Friday, July 11.
NASA’s SCaN Program serves as the management office for the agency’s space communications and navigation. More than 100 NASA and non-NASA missions rely on SCaN’s two networks, the Near Space Network and the Deep Space Network, to support astronauts aboard the International Space Station and future Artemis missions, monitor Earth’s weather, support lunar exploration, and uncover the solar system and beyond.

Video: 00:01:40 Proba-3 artificially created what is normally a rare natural phenomenon: a total solar eclipse.
In a world first, ESA’s Proba-3 satellites flew in perfect formation, blocking the Sun’s bright disc to reveal its fiery corona. This enigmatic outer layer burns millions of degrees hotter than the Sun’s surface and drives the solar storms that can disrupt life on Earth.
With its first artificial eclipse, Proba-3 has captured detailed images of this mysterious region, offering scientists new insights into our star’s behaviour.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Instruments in space are helping scientists map wastewater plumes flowing into the Pacific Ocean from the heavily polluted Tijuana River, seen here with the San Diego sky-line to the north. NOAA Proof-of-concept results from the mouth of the Tijuana River in San Diego County show how an instrument called EMIT could aid wastewater detection.
An instrument built at NASA’s Jet Propulsion Laboratory to map minerals on Earth is now revealing clues about water quality. A recent study found that EMIT (Earth Surface Mineral Dust Source Investigation) was able to identify signs of sewage in the water at a Southern California beach.
The authors of the study examined a large wastewater plume at the mouth of the Tijuana River, south of Imperial Beach near San Diego. Every year, millions of gallons of treated and untreated sewage enter the river, which carries pollutants through communities and a national reserve on the U.S.-Mexico border before emptying into the Pacific Ocean. Contaminated coastal waters have been known to impact human health — from beachgoers to U.S. Navy trainees — and harm marine ecosystems, fisheries, and wildlife.
For decades scientists have tracked water quality issues like harmful algal blooms using satellite instruments that analyze ocean color. Shades that range from vibrant red to bright green can reveal the presence of algae and phytoplankton. But other pollutants and harmful bacteria are more difficult to monitor because they’re harder to distinguish with traditional satellite sensors.
A plume spreads out to sea in this image captured off San Diego by the Sentinel-2 satellite on March 24, 2023. Both a spectroradiometer used to analyze water samples (yellow star) and NASA’s EMIT identified in the plume signs of a type of bacterium that can sicken humans and animals.SDSU/Eva Scrivner That’s where EMIT comes in. NASA’s hyperspectral instrument orbits Earth aboard the International Space Station, observing sunlight reflecting off the planet below. Its advanced optical components split the visible and infrared wavelengths into hundreds of color bands. By analyzing each satellite scene pixel by pixel at finer spatial resolution, scientists can discern what molecules are present based on their unique spectral “fingerprint.”
Scientists compared EMIT’s observations of the Tijuana River plume with water samples they tested on the ground. Both EMIT and the ground-based instruments detected a spectral fingerprint pointing to phycocyanin, a pigment in cyanobacteria, an organism that can sicken humans and animals that ingest or inhale it.
‘Smoking Gun’
Many beachgoers are already familiar with online water-quality dashboards, which often rely on samples collected in the field, said Christine Lee, a scientist at JPL in Southern California and a coauthor of the study. She noted the potential for EMIT to complement these efforts.
“From orbit you are able to look down and see that a wastewater plume is extending into places you haven’t sampled,” Lee said. “It’s like a diagnostic at the doctor’s office that tells you, ‘Hey, let’s take a closer look at this.’”
Lead author Eva Scrivner, a doctoral student at the University of Connecticut, said that the findings “show a ‘smoking gun’ of sorts for wastewater in the Tijuana River plume.” Scrivner, who led the study while at San Diego State University, added that EMIT could be useful for filling data gaps around intensely polluted sites where traditional water sampling takes a lot of time and money.
EMIT’s Many Uses
The technology behind EMIT is called imaging spectroscopy, which was pioneered at JPL in the 1980s. Imaging spectrometers developed at JPL over the decades have been used to support areas ranging from agriculture to forest health and firefighting.
When EMIT was launched in July 2022, it was solely aimed at mapping minerals and dust in Earth’s desert regions. That same sensitivity enabled it to spot the phycocyanin pigments off the California coast.
Scrivner hadn’t anticipated that an instrument initially devoted to exploring land could reveal insights about water. “The fact that EMIT’s findings over the coast are consistent with measurements in the field is compelling to water scientists,” she said. “It’s really exciting.”
