Wonders Instrumentation and Certification
From its perspective on the spaceport station, AWEs Advanced Mesospheric Temperature Mapper (AMTM) instrument will scan the mesopause below it. AWEs AMTM consists of four similar telescopes, which together make up a wide-field-of-view imaging radiometer, an instrument that measures the brightness of light at particular wavelength varieties. The relative brightness of different wavelengths can be utilized to produce temperature level maps, which in turn expose how AGWs are moving through the atmosphere. It will be the most comprehensive research study of AGWs and their effects on the upper atmosphere ever performed.
As a payload headed to the space station, AWE was required to hold four essential security evaluations. The objective was effectively licensed as a station payload at its last review in July 2023. Part of this certification included “sharp edge” screening with astronaut gloves to make sure security during AWEs installation and upkeep on the exterior of the spaceport station.
The Future of AWEs Research
Wonder is the first NASA mission to attempt this kind of science to provide insight into how terrestrial and space weather interactions might affect satellite communications and tracking in orbit.
Following AWEs setup on the International Space Station, the groups focus will be to share the instruments data and results with the science community and the general public.
By evaluating the mesopauses airglow, AWE will advance our knowledge of climatic gravity waves impact on space weather and satellite communications. At the mesopause, where AWE will make its measurements, AGWs are exposed by vibrant bands of light in our environment known as airglow. From its vantage point on the area station, AWEs Advanced Mesospheric Temperature Mapper (AMTM) instrument will scan the mesopause listed below it. As a payload headed to the space station, AWE was needed to hold 4 crucial security evaluations. Part of this certification included “sharp edge” testing with astronaut gloves to guarantee security throughout AWEs installation and upkeep on the outside of the area station.

NASAs AWE mission, set to launch to the ISS, will analyze climatic waves and their results on area weather through the Earths natural airglow, notifying future satellite communication and tracking.
NASAs Atmospheric Waves Experiment, or AWE, mission is arranged to release to the International Space Station (ISS) on November 9, 2023, where it will use a natural, ethereal radiance in Earths sky to study waves in our planets atmosphere.
AWEs Design and Objective
Developed by Utah State Universitys Space Dynamics Laboratory in North Logan, Utah, AWE will be installed on the exterior of the spaceport station. From this perch, AWE will look down toward Earth, tracking undulations in the air referred to as climatic gravity waves (AGWs).
Mainly originating in the most affordable level of the atmosphere, AGWs may be triggered by strong weather occasions such as tornadoes, cyclones, or perhaps thunderstorms. These weather events can briefly push pockets of high-density air upwards into the environment before the air sinks back down. This up-and-down bobbing often leaves distinctive ripples patterns in the clouds.
Studying AGWs and Space Weather
AGWs extend all the method to space, where they contribute to whats referred to as space weather condition– the tumultuous exchange of energy in the location surrounding our planet that can interfere with satellite and interactions signals. Wonder will measure AGWs at a climatic layer that starts some 54 miles (87 kilometers) in elevation, known as the mesopause.
This photo shows examples of cloud patterns triggered by climatic gravity waves (AGWs). Warmer, denser air from lower in the atmosphere holds more water, so as weather occasions like wind and storms push those pockets of air to higher altitudes, that water forms clouds at the crests of those waves.

” This is the first time that AGWs, particularly the small ones, will be determined internationally at the mesopause, the gateway to the space,” stated Michael Taylor, professor of physics at Utah State University and principal private investigator for the mission. “More importantly, this is the very first time we will have the ability to measure the effects of AGWs on area weather condition.”
Airglow and AWEs Methodology
At the mesopause, where AWE will make its measurements, AGWs are revealed by vibrant bands of light in our atmosphere known as airglow. AWE will “see” these waves by tape-recording variations of airglow in infrared light, a wavelength variety too long for human eyes to see. At these altitudes our atmosphere dips to its coldest temperatures– reaching as low as -150 degrees Fahrenheit (-101 degrees Celsius)– and the faint glow of infrared light is at its brightest.
By enjoying that infrared airglow grow brighter and dimmer as waves move through it, AWE will make it possible for researchers to calculate the size, power, and dispersion of AGWs like never previously. It was also designed to see smaller AGWs, discovering short-scale ripples in airglow that previous missions would miss out on.
” AWE will have the ability to fix waves at finer horizontal scales than what satellites can generally see at those elevations, which belongs to what makes the objective special,” said Ruth Lieberman, AWE objective scientist at NASAs Goddard Space Flight Center in Greenbelt, Maryland.
