NASA to Launch SNIFS, Sun’s Next Trailblazing Spectator

July will see the launch of the groundbreaking Solar EruptioN Integral Field Spectrograph mission, or SNIFS. Delivered to space via a Black Brant IX sounding rocket, SNIFS will explore the energy and dynamics of the chromosphere, one of the most complex regions of the Sun’s atmosphere. The SNIFS mission’s launch window at the White Sands Missile Range in New Mexico opens on Friday, July 18. 

The chromosphere is located between the Sun’s visible surface, or photosphere, and its outer layer, the corona. The different layers of the Sun’s atmosphere have been researched at length, but many questions persist about the chromosphere. “There’s still a lot of unknowns,” said Phillip Chamberlin, a research scientist at the University of Colorado Boulder and principal investigator for the SNIFS mission.

The chromosphere lies just below the corona, where powerful solar flares and massive coronal mass ejections are observed. These solar eruptions are the main drivers of space weather, the hazardous conditions in near-Earth space that threaten satellites and endanger astronauts. The SNIFS mission aims to learn more about how energy is converted and moves through the chromosphere, where it can ultimately power these massive explosions.  

“To make sure the Earth is safe from space weather, we really would like to be able to model things,” said Vicki Herde, a doctoral graduate of CU Boulder who worked with Chamberlin to develop SNIFS.

The SNIFS mission is the first ever solar ultraviolet integral field spectrograph, an advanced technology combining an imager and a spectrograph. Imagers capture photos and videos, which are good for seeing the combined light from a large field of view all at once. Spectrographs dissect light into its various wavelengths, revealing which elements are present in the light source, their temperature, and how they’re moving — but only from a single location at a time. 

The SNIFS mission combines these two technologies into one instrument.  

“It’s the best of both worlds,” said Chamberlin. “You’re pushing the limit of what technology allows us to do.” 

By focusing on specific wavelengths, known as spectral lines, the SNIFS mission will help scientists to learn about the chromosphere. These wavelengths include a spectral line of hydrogen that is the brightest line in the Sun’s ultraviolet (UV) spectrum, and two spectral lines from the elements silicon and oxygen. Together, data from these spectral lines will help reveal how the chromosphere connects with upper atmosphere by tracing how solar material and energy move through it. 

The SNIFS mission will be carried into space by a sounding rocket. These rockets are effective tools for launching and carrying space experiments and offer a valuable opportunity for hands-on experience, particularly for students and early-career researchers.

“You can really try some wild things,” Herde said. “It gives the opportunity to allow students to touch the hardware.” 

Chamberlin emphasized how beneficial these types of missions can be for science and engineering students like Herde, or the next generation of space scientists, who “come with a lot of enthusiasm, a lot of new ideas, new techniques,” he said. 

The entirety of the SNIFS mission will likely last up to 15 minutes. After launch, the sounding rocket is expected to take 90 seconds to make it to space and point toward the Sun, seven to eight minutes to perform the experiment on the chromosphere, and three to five minutes to return to Earth’s surface.

The rocket will drift around 70 to 80 miles (112 to 128 kilometers) from the launchpad before its return, so mission contributors must ensure it will have a safe place to land. White Sands, a largely empty desert, is ideal. 

Herde, who spent four years working on the rocket, expressed her immense excitement for the launch. “This has been my baby.”

What has Webb Taught Us About Rocky Exoplanets So Far?

Universe Today - Thu, 07/17/2025 - 2:02pm

The JWST has pushed the boundaries of exoplanet characterization. But one thing it hasn't done yet is to determine if rocky exoplanets close to our Solar System can retain their atmospheres. The authors of a new study propose a new "five-scale height challenge" that will help astronomers obtain more precise atmospheric information on rocky exoplanets using Webb.

Satellite Constellations Are Too Bright, Threatening Astronomy and Our Night Sky

Universe Today - Thu, 07/17/2025 - 2:02pm

Our quest for universal internet is stealing the stars. Thousands of satellites now travelling across the night sky are far brighter than international safety limits, turning what was once humanity's window to the cosmos into a highway of artificial lights. New research reveals that major constellations like Starlink and OneWeb are breaking the brightness rules designed to protect both cutting edge astronomy and the simple joy of stargazing potentially robbing future generations of the dark skies that have inspired wonder for centuries.

Earth Was Born With Water; No Delivery Needed

Universe Today - Thu, 07/17/2025 - 2:02pm

The source of Earth's water is one of the most compelling questions facing scientists. Earth's habitability depends on multiple factors, but water is the basis for life, and it had to come from somewhere. Did comets and meteorites deliver it after Earth formed? Or did water become part of our planet as it formed?

A Lunar Base Could Start with a Dome over a Crater Made of Regolith

Universe Today - Thu, 07/17/2025 - 2:02pm

When astronauts live on the Moon permanently, they're going to need a safe habitat, ideally made out of local construction material. A new paper suggests that lunar astronauts could cover a 17-meter crater with a dome made from a lunar regolith-based geopolymer. A 3D printer would extrude a paste made of lunar regolith that would be sintered together into the shape of the dome. This would provide protection from radiation and could even maintain a pressurized habitat.
