I work at @NASAJPL to measure our planet and other objects in the solar system. But the tweets are all mine.

This video shared by @JohnKerry describes the EMIT imaging spectrometer's detection of CH4 superemitters from the international space station. We have now detected over 1000 plumes!.
Our friends at @NASA are helping the world identify methane super emitters from the International Space Station. Methane contributes 30% of current warming - and rapidly reducing methane emissions is crucial to our global climate, health, food security & energy security goals.

In a notable "first," we demonstrate on-orbit alignment, measuring and correcting a sub-micron tilt in the focal plane array. That's tiny! If the spectrometer were the size of the continental USA, this adjustment would be approximately the length of a pingpong table.

Our experiments demonstrate that this approach is successful, approaching the fidelity of manual field spectroscopy in some cases, and enabling new and more accurate products across diverse Earth science disciplines.

Accurate spectroscopy is vital to achieve consistent mapping results with orbital imaging spectrometers. EMIT takes a unique approach to this challenge, with just six optical elements, no shutter, and no onboard calibration systems.

AVIRIS-NG strikes again! Great job, team.
Here's something to cheer(s) about going into the weekend! 🍷. Thanks to an airborne instrument developed here at JPL, scientists detected a costly infection in cabernet sauvignon grapevines before they showed symptoms visible to the human eye.
