The PACE (Plankton, Aerosol, Cloud, ocean Ecosystemobjective has actually provided its Functional information back to scientistsa task enabled in part by ingenious, data-storing innovation from NASA’s Near Space Networkwhich presented 2 essential improvements for PACE and other upcoming science objectives.
As a satellite orbits in area, its systems produce vital information about the spacecraft’s health, area, battery life, and more. All of this takes place while the objective’s science instruments catch images and information supporting the satellite’s total goal.
This information is then encoded and returned to Earth by means of radio waves through NASA’s Near Space Network and Deep Space Network– however not without obstacles.
One obstacle is severe ranges, where disturbances or hold-ups prevail. Satellite disturbances resemble what web users experience in the world with buffering or malfunctioning links. If an interruption happens, Delay/Disruption Tolerant Networking, or DTN, can securely keep and forward the information as soon as a course opens.
NASA’s Near Space Network incorporated DTN into 4 brand-new antennas and the PACE spacecraft to display the advantage this innovation can have for science objectives. The network, which supports interactions for space-based objective within 1.2 million miles of Earth, is continuously boosting its abilities to support science and expedition objectives.

“DTN is the future of area interactions, offering robust security of information that might be lost due to an interruption,” stated Kevin Coggins, deputy partner administrator for NASA’s Area Communications and Navigation (SCaN) program. “PACE is the very first functional science objective to utilize DTN, and we are utilizing it to transfer information to objective operators keeping an eye on the batteries, orbit, and more. This details is crucial to objective operations.”
SPEEDa satellite situated about 250 miles above Earth, is gathering information to assist scientists much better comprehend how the ocean and environment exchange co2, procedure climatic variables related to air quality and environment, and screen ocean health by studying phytoplankton– small plants and algae.
While PACE is the very first functional science user of DTN, presentations of the innovation have actually been done formerly on the International Space Station.
In addition to DTN, the Near Space Network dealt with industrial partner, Kongsberg Satellite Services in Norway to incorporate 4 brand-new antennas into the network to support PACE.
These brand-new antennas, in Fairbanks, Alaska; Wallops Island, Virginia; Punta Arenas, Chile; and Svalbard, Norway, enable objectives to downlink terabytes of science information simultaneously. Simply as researchers and engineers continuously enhance their instrument abilities, NASA likewise advances its interactions systems to make it possible for objectives near Earth and in deep area.
As PACE orbits Earth, it will downlink its science information 12 to 15 times a day to 3 of the network’s brand-new antennas. In general, the objective will send out down 3.5 terabytes of science information every day.
Network ability methods like DTN and the 4 brand-new antennas are the most recent improvements to the Near Space Network’s brochure of services to support science objectives, human spaceflight, and innovation experiments.
“NASA’s Near Space Network now has extraordinary versatility to get researchers and operations supervisors more of the valuable info they require to guarantee their objective’s success,” stated Coggins.
In addition to these brand-new abilities, the network is likewise increasing the variety of industrial antennas within its portfolio. In 2023, NASA released the Near Space Network Services ask for proposition to look for industrial companies for combination into the network’s broadening portfolio. With an increasing capability, the network can support extra science objectives and downlink chances.
The Near Space Network is moneyed by NASA’s Space Communications and Navigation (SCaN) program workplace at NASA Headquarters in Washington and ran out of NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
