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!

@javieroger23 @iiama_upv @SRON_Space @Kayrros @ghgsat Well done @javieroger23 @GuanterLuis @itziraloi ! Another emitter exposed. Keep up the good work.

Now in print! The performance and calibration of EMIT - NASA's remote imaging spectrometer on the International Space Station. https://t.co/6tN0vLHvSM

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.

A lesson in remote sensing of snow from the one and only Jeff Dozier! What better than a spectrometer to measure snow’s light absorption and resulting melt rates? #AGU23

Breaking news from EMIT: the first global maps of surface minerals in arid regions! Continental-scale mineralogy at 60m resolution yields some surprisingly beautiful maps. It's astonishing how much we still have to learn about our planet.

Here’s @knobelsp describing PACE-PAX at #AGU23 - multi-aircraft validation of the PACE mission products with the Pacific as the laboratory!

Come see EMIT at #AGU2023 ! From continent-scale mineral maps to facility-scale greenhouse gas point sources, the first year of EMIT observations is a tantalizing glimpse at the potential of imaging spectroscopy for understanding our planet.

[Lunar Trailblazer @LunarTrailblazr]

Lunar Thermal Mapper (LTM) has been integrated with the Lunar Trailblazer spacecraft! 🚀

Built by @OxfordAOPP and contributed by @spacegovuk, LTM will work together with Lunar Trailblazer's HVM3 instrument to find lunar water.

@kaitlinmgold @NASAJPL @FerRomeroGalvan @RyanPavlick Congrats @kaitlinmgold! It's great to see this work bear fruit.

[David Ray Thompson @davidray]

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. https://t.co/fHSrdetEnz

A shout out to EMIT by @KeelyRoth of @planet at #IGARSS2023. Thanks! Looking forward to Tanager.
