NASA’s Sun Radio Interferometer Space Experiment, known as SunRISE, is a unique mission involving six compact CubeSats, each comparable in size to a toaster. These satellites will collaboratively investigate solar phenomena by monitoring low radio frequency emissions. This is crucial for understanding the Sun’s capacity to produce severe space weather events, namely solar particle storms, which pose risks to spacecraft and astronauts. The SunRISE mission is an essential part of NASA’s efforts to comprehend the dynamics behind the Sun’s explosive activities.
Unlike typical NASA missions with a single spacecraft or occasionally several, SunRISE stands out with its cluster of six satellites. Recently, the team completed the construction of these identical satellites, each resembling the size of a cereal box. They are now in storage, awaiting final testing and their journey to space. SunRISE is set to be launched as part of a shared mission on a United Launch Alliance Vulcan rocket, under the auspices of the United States Space Force’s Space Systems Command.

SunRISE’s Contribution to Solar Science
Post-launch, these six SmallSats will function collectively as a large radio antenna in space. The mission’s primary focus is to investigate the physics of solar atmospheric explosions, aiming to provide insights that could protect astronauts and space equipment from hazardous particle showers.
Jim Lux, SunRISE’s project manager at NASA’s Jet Propulsion Laboratory (JPL) in Southern California, highlights the significance of this phase, acknowledging the challenges of pioneering small, compact space vehicles. The collaborative effort spans multiple institutions and companies, with anticipation growing for the first solar images in these radio wavelengths.
Monitoring Solar Radio Phenomena
Despite their small size, these satellites have a crucial role in studying solar radio bursts, generated in the Sun’s outer atmosphere. These bursts occur due to electrons being accelerated during events like coronal mass ejections and solar flares. Such particles can harm spacecraft electronics and endanger astronauts. Understanding the genesis and interconnections of solar radio bursts, coronal mass ejections, and solar flares is a major scientific pursuit, with SunRISE poised to provide valuable insights. This mission could eventually aid in predicting solar particle events impacting Earth.
Earth-based monitoring of such phenomena is limited, as our atmosphere obstructs the relevant radio wavelengths. Hence, a space-based monitoring system necessitates a radio telescope larger than any previously used in space, a role SunRISE is designed to fulfill.
Technical Details of SunRISE
To detect solar radio events, the SmallSats will orbit approximately 6 miles apart, deploying radio antennas extending 10 feet. By tracking their relative positions and precisely timing their observations, the satellites will create a unified data stream, enabling the production of solar images through a technique known as interferometry.
Andrew Romero-Wolf, deputy project scientist at JPL, notes the uniqueness of SunRISE: instead of multiple instruments on a single spacecraft, it utilizes multiple satellites to act as one instrument.
Overview of the SunRISE Mission
SunRISE operates under NASA’s Heliophysics Division as a Mission of Opportunity within the Science Mission Directorate. It’s part of NASA’s Explorers Program, managed by the Goddard Space Flight Center in Maryland. The mission is led by Justin Kasper at the University of Michigan and managed by JPL in Southern California, a division of Caltech in Pasadena. Utah State University’s Space Dynamics Laboratory constructed the spacecraft, with JPL providing mission operations and management.

Wow, this SunRise mission sounds amazing! never knew nasa was doing stuff like this with mini-satellites. Super cool how they can work together to study the sun.
so they’re launching these on a Vulcan rocket, thats pretty neat. Always thought space launches were just for big satellites, never thought about small ones like these.
read about coronal mass ejections in a sci-fi book once, didn’t know they were a real thing! These SunRISE satellites could be a game-changer for space weather forecasting.
i’m curious, how do these CubeSats even survive the intense solar radiation? Seems like a big challenge for such small devices, right?
This is fascinating! Learning about the sun’s mysteries is important, but I wonder how much this all costs? Space stuff ain’t cheap, you know.
