Five research aircraft will support a Student Airborne Research Program (SARP) mission out of Ellington Field in Houston. Flights are expected from Wednesday, June 3 to Saturday, June 13. During the mission, select maneuvers will be conducted at low altitudes over the Houston area. 

Pilots will fly remote sensing payloads in raster patterns, or parallel back-and-forth lines. The instruments flown could help researchers map the movement of the gases and particles that make up Earth’s atmosphere, changes to the lowest part of the atmosphere near the coastline, and the natural processes affecting the land and water in that area. The flights will primarily take place in the Houston area, with some extending over the Gulf of America.  

While many of the flights will operate at higher altitudes, a WP-3D Orion will conduct maneuvers as low as 1,000 feet above ground level. Owned and operated by the National Oceanic and Atmospheric Administration (NOAA), this aircraft is used as a hurricane hunter and has supported several airborne science missions for NASA. It is equipped with a multitude of scientific instrumentation, radars, and recording systems for both in-flight and remote sensing measurements of the atmosphere, the Earth, and its environment. 

The NASA-operated aircraft participating in the mission also are equipped with a variety of remote sensing instruments, including two lidars, a synthetic-aperture radar, an imaging spectrometer, and two spectrometers. 

The operations will involve the agency’s Gulfstream V (N95NA), Gulfstream C-20A (N802NA), and Gulfstream III (N520NA), as well as NOAA’s WP-3D Orion (N43RF) and a King Air B200 aircraft (N46L) owned by Dynamic Aviation and contracted by NASA. The flights can be tracked in real time at NASA Airborne Science Program Tracker

The SARP effort is an eight-week summer internship program that provides undergraduate students with hands-on experience by engaging in field research and data analysis and with access to one or more NASA Airborne Science Program flying science laboratories.

What’s Up: June 2026 Skywatching Tips from NASA

2026-06-01 18:13

Venus and Jupiter meet after sunset, the Moon passes in front of Venus, summer begins, and deep-sky treasures rise into view.

Skywatching Highlights

  • June 9: Venus and Jupiter conjunction
  • June 11–15: Mercury joins Venus and Jupiter after sunset
  • June 17: Moon passes in front of Venus &  close Moon and Venus pairing
  • June 21: June solstice &  start of astronomical summer
  • June: Summer Triangle and deep-sky observing targets rise into view

Transcript

Planets gather after sunset, the Moon passes in front of Venus, summer officially begins and deep sky treasures rise into view. That’s What’s Up for June.

Early this month, look west shortly after sunset to see Venus and Jupiter. They are two of the brightest planets in our sky and around June 9th, they’ll appear close together after sunset. This is called a planetary conjunction—when two planets appear near each other from our point of view on Earth, even though they’re still millions of miles apart in space.

From June 11th through June 15th, Mercury joins the scene, creating a mini parade of planets low in the western sky. This happens because the planets orbit the sun along nearly the same path in our sky, called the ecliptic. So from our point of view on Earth, they sometimes appear to gather in the same part of the sky.

Venus will be the brightest and easiest to spot with Jupiter nearby. Mercury will sit lower toward the horizon, so you will need a clear view to the west to catch it in the glow of twilight.

On June 17th, from some locations the Moon will pass in front of Venus. This is called a lunar occultation. For viewers in the right viewing path, Venus will look like it disappears behind the Moon, then reappears later. The event will be visible from parts of the United States, Canada, Brazil and Venezuela. Outside of the exact viewing path, many skywatchers may still see a close pairing of the Moon and Venus, but this comes with an important safety note. For many viewers this will happen during the daytime.

If you’re trying to observe the occultation, do not point binoculars, a telescope, or a camera near the sun unless you’re using proper solar safety equipment. Looking at or near the sun through optics can cause serious eye injury.

June also brings the summer solstice. In the Northern Hemisphere, the June solstice marks the start of the astronomical summer. In Pacific time, it happens on Sunday, June 21st at 1:24 a.m.

Around the solstice, the Northern Hemisphere gets its longest days and shortest nights of the year.

But here’s a fun fact, the longest day does not usually line up exactly with the earliest sunrise or latest sunset. For example, in Los Angeles, the earliest sunrise comes before the solstice, while the latest sunset comes after it.

And once the sky gets dark, summer brings some favorite targets for telescope users and astrophotographers. First, look for the Summer Triangle, formed by the bright stars Vega, Altair, and Deneb. Inside and around this region are deep sky objects like the Dumbbell Nebula, the Ring Nebula, the North America Nebula, and the Veil Nebula. The Dumbbell Nebula, also known as Messier 27, was the first planetary nebula ever discovered.

These objects are not bright like planets, but with telescopes or long exposure photography, they reveal glowing gas, dying stars, and stellar nurseries in our galaxy.

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.

No matter how you spend your summer – building projects like the Hack Club’s Stardance Challenge, jumping into real NASA research through citizen science, or exploring possible NASA career paths – there’s a launch pad waiting for you. And remember, NASA’s STEM Resources website is available year-round to serve as your one-stop hub for hands-on activities, videos, articles, and more to spark curiosity and fuel big ideas.

Gravity Waves From Super Typhoon Sinlaku

2026-06-01 04:01

Gravity waves in the upper atmosphere appear as concentric rings in a nighttime, black and white satellite image. Clouds from a typhoon are also visible.
Atmospheric gravity waves generated by Super Typhoon Sinlaku are visible via mesospheric airglow in this nighttime image acquired with the VIIRS (Visible Infrared Imaging Radiometer Suite) on the NOAA-20 satellite on April 12, 2026, Universal Time (April 13 local time).
NASA Earth Observatory/Michala Garrison

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 nearly complete rings 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.

The signature of gravity waves in the stratosphere appears as concentric rings in infrared satellite data.
Thermal energy from gravity waves produced by Super Typhoon Sinlaku was detected in the stratosphere by the AIRS (Atmospheric Infrared Sounder) instrument on NASA’s Aqua satellite on April 13, 2026.

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.”
