EMIT (Earth Surface Mineral Dust Source Investigation) was built to help scientists understand how dust affects climate. It can also pinpoint emissions of the potent greenhouse gas. NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) mission is mapping the prevalence of key minerals in
This image shows a methane plume 2 miles long that NASA’s Earth Surface Mineral Dust Source Investigation mission detected southeast of Carlsbad, New Mexico.

Methane absorbs infrared light in a unique pattern – called a spectral fingerprint – that EMIT’s imaging spectrometer can discern with great precision andThe new observations stem from the broad coverage of the planet afforded by the space station’s orbit, as well as from EMIT’s ability to scan swaths of Earth’s surface dozens of miles wide while resolving areas as small as a soccer field.
A methane plume at least 3 miles long billows into the atmosphere south of Tehran, Iran. The plume, detected by NASA’s Earth Surface Mineral Dust Source Investigation mission, comes from a major landfill, where methane is a byproduct of decomposition.

Lucy Zipped Past Earth to get a Gravitational Assist Towards Jupiter's TrojansGravitational assists are marvels of orbital mechanics. Usually, they are done for a combination of fuel (i.e., cost) savings and speed, as it is sometimes faster to take multiple trips around planets in the inner solar system to reach locations in the outer solar system more quickly. Lucy recently made such a maneuver on its … Continue reading 'Lucy Zipped Past Earth to get a Gravitational Assist Towards Jupiter’s Trojans'
