Dive into NASA Research Through Citizen Science

NASA invites people of all ages and backgrounds to do NASA science as a part of real science projects that rely on volunteers. Citizen Science is a great way to make new friends, meet some scientists, and help NASA solve mysteries of the universe this summer – using just a phone or computer. You can join from anywhere, participate on your own schedule, and dive right into real research using actual mission data. Here are two examples:

• Through Space Cloud Watch, you can help NASA study noctilucent clouds. Noctilucent means “night-shining,” and that’s exactly what they do! During summer twilight at high latitudes, these clouds catch sunlight and appear to glow even in a darkened sky. Take a photo and submit a report to help scientists track how these rare clouds are changing.
• Take your cloud‑watching to another planet with Cloudspotting on Mars, where you review real NASA images to identify clouds above the Red Planet and help scientists understand Martian weather.

Curious about what other projects you might enjoy? See all current Citizen Science opportunities available through NASA’s Science Mission Directorate.

In mid-April 2026, Super Typhoon Sinlaku churned across the North Pacific Ocean and brought heavy rain and flooding to the Mariana Islands. The storm reached “violent typhoon” status—the highest intensity on the scale used by the Japan Meteorological Agency and roughly equivalent to a category 5 storm on the Saffir-Simpson wind scale. Sinlaku was one of only a handful of tropical cyclones of that intensity known to have occurred so early in the year in the region, meteorologists noted.

Sinlaku rapidly intensified over the ocean before its impacts reached land. Around the time of this strengthening, satellites began to detect that the typhoon’s effects also extended upward, into the upper atmosphere.

The nighttime image above, acquired with the VIIRS (Visible Infrared Imaging Radiometer Suite) on the NOAA-20 satellite, shows atmospheric gravity waves radiating from the typhoon. These waves, resembling ripples on a pond, were made visible to the sensor via airglow in the mesosphere. Airglow occurs when atoms and molecules, excited by sunlight during the day, later emit light to release excess energy.

The release of latent heat near the eyewalls of tropical cyclones is known to drive convection and the formation of tall cumulonimbus clouds. These “hot towers” can rise out of the troposphere, the lowest layer of the atmosphere, and generate waves that propagate into the stratosphere and mesosphere above. An analysis of past tropical cyclones revealed that gravity waves often occur around the time that storms are intensifying. Indeed, in the 24 hours prior to the acquisition of the image above, Sinlaku had strengthened from a category 2 to a category 5 storm.

“We’re seeing waves propagating radially and upward, in a cone-like shape,” said Joan Alexander, senior research scientist at NorthWest Research Associates. Alexander was surprised to see well-defined waves in the mesospheric airglow above the storm. Winds in the upper atmosphere can dissipate the waves before they reach such high altitudes, Alexander explained, but relatively light stratospheric winds at the storm’s latitude in April 2026 may have helped preserve them.

A relatively low amount of moonlight was fortuitous, as well. The VIIRS day-night band is sensitive to airglow in the mesosphere but also observes reflected moonlight. The Moon was about 25 percent illuminated on April 12, so some light reflected off clouds in the troposphere was visible, but not enough to overpower the signal from the airglow.

Sinlaku’s gravity waves, in addition to appearing high in the atmosphere via airglow, were observed lower in the atmosphere by the AIRS (Atmospheric Infrared Sounder) instrument on NASA’s Aqua satellite. The image above depicts thermal emissions from gravity waves in the stratosphere on April 13. The rippling pattern appeared in April 14 observations, as well, indicating the storm’s continuing effects on the atmosphere.

Observing atmospheric gravity waves, particularly those caused by tropical cyclones, goes beyond scientific curiosity. Practical implications could include improved monitoring of storm development. “We’d like to use gravity waves to tell us if a storm is intensifying,” Alexander said, “which can be difficult to know, especially over the open ocean.” A geostationary satellite with the proper infrared imager would be able to observe gravity waves and track tropical cyclone evolution, she and colleagues have argued.

Furthermore, it’s critical to account for processes in the stratosphere in weather models, said Laura Holt, also a senior research scientist at NorthWest Research Associates. Stratospheric wind patterns are factors in long-term forecasts of the next Northern Hemisphere winter, for example, and tropical cyclones have a disproportionate influence because their sustained, intense convection drives prolonged gravity wave forcing of the stratosphere.

The effect of gravity waves even reaches into the realm of space weather. “For a while, people have seen signatures of hurricanes in ionospheric weather,” Holt said. Gravity waves can lead to traveling ionospheric disturbances—large-scale ripples in plasma density—and in some cases plasma bubbles, both of which can disrupt satellite signals and radio communications. “With space weather in particular,” Holt added, “a single event such as a tropical cyclone can be very important.”

NASA’s Roman Space Telescope Primary Mirror Gets Last Look

Engineers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, have completed their final inspection of a key element for the agency’s Nancy Grace Roman Space Telescope: the primary mirror. This 7.9-foot (2.4-meter) mirror will collect and focus light from cosmic objects near and far, helping Roman capture stunning panoramas of space.

“The Roman engineering team laid eyes on the telescope for the final time before it, in turn, becomes the eyes of humanity, revealing the wonders of the cosmos,” said J. Scott Smith, the Roman telescope manager at NASA Goddard. “It is a profoundly humbling moment to witness the culmination of hard work from so many dedicated individuals, teams, and partner organizations, including L3Harris.”

On May 20, engineers turned the Roman observatory onto its side and deployed the “hood” that will be stowed for launch to protect the mirror. Then the team conducted a meticulous visual inspection to ensure no specks fell onto the mirrors during testing and confirm there are no changes in the mirror path and alignment.

“We developed a method of using a high-resolution camera equipped with a very powerful zoom lens to do a multi-purpose inspection,” said Bente Eegholm, optics lead for Roman’s Optical Telescope Assembly at NASA Goddard. “The mirror passed with flying colors, keeping the mission on track for an early September launch.”

The team carefully observed the optics along the path light will follow to the Wide Field Instrument detector array and confirmed it remains in proper alignment following the observatory shake test.

“In order to gather very sensitive measurements of objects strewn throughout space, all of Roman’s components have to be ultraprecise,” Eegholm said. “The primary mirror certainly delivers on that precision.”

Roman’s primary mirror sports a layer of silver less than 400 nanometers thick — about 200 times thinner than a human hair. The silver coating was specifically chosen for Roman because of how well it reflects near-infrared light. By contrast, the Hubble Space Telescope’s mirror is coated with layers of aluminum and magnesium fluoride to optimize visible and ultraviolet light reflectivity. Likewise, the James Webb Space Telescope’s mirrors have a gold coating to suit its longer wavelength infrared observations.

The Roman mirror is so finely polished that the average bump on its surface is only 1.2 nanometers tall — more than twice as smooth as the mission requires. If the mirror were scaled up to Earth’s size, these bumps would be just a quarter of an inch high.

Since it’s made of a specialty ultralow-expansion glass, the mirror will resist flexing, which can happen to materials during temperature changes (like going from balmy Earth conditions to the deep freeze of space). This preserves Roman’s image quality, because if the primary mirror changed shape, it would distort the images from the telescope.

“We’re really proud of the amazing optical system we’ve delivered for the Roman mission alongside our partners at L3Harris,” said Josh Abel, lead Optical Telescope Assembly systems engineer at NASA Goddard. “Now that it’s assembled, aligned, and all shined up, we’re ready to go.”

Now, the Roman team is preparing to ship the observatory to the launch site at NASA’s Kennedy Space Center in Florida in the coming weeks. NASA expects the mission to begin returning incredible cosmic vistas within several months after launch.
