Meet Heather Williams, SAO's first Chief Operating Officer! cfa.harvard.edu/news/heather-w…

Want to know what's in the air we breathe? With the NASA and Center for Astrophysics | Harvard & Smithsonian TEMPO mission, we're hoping to get answers!

Join us Monday, 4/24, at 12:00 pm ET for a Reddit AMA and learn more about how TEMPO will transform our understanding of air quality. reddit.com/r/askscience/

In one week! Phil (Newsletter link in bio) Plait and Dr. Jessie Christiansen @ #ExSSV present UNDER ALIEN SKIES: A SIGHTSEER'S GUIDE TO THE UNIVERSE

Four years ago today from our Center for Astrophysics | Harvard & Smithsonian, you got this first look at a black hole.

Right now, a washing machine-sized scientific instrument hovers above us.

Launched today on the Intelsat 40e satellite, TEMPO Mission, a Center for Astrophysics | Harvard & Smithsonian and @nasa_langley collaboration, is the first space-based instrument to track air pollutants hourly across North America.

I remember crowding around my school's TV to witness new achievements in space exploration. I hope this launch offers the same national experience of hope and awe as we drastically advance the conversation on how air pollution affects nature and communities across North America.

Spacecraft separation confirmed! The Intelsat satellite hosting our NASA Earth & Center for Astrophysics | Harvard & Smithsonian #TEMPO mission is flying free from its SpaceX Falcon 9 rocket and on its way to geostationary orbit.

The night is here and we’re ready!

The Sun has set here in Cape Canaveral, Florida. Less than 5 hours until @Intelsat 40E blasts off from Launch Complex 40, carrying our TEMPO Mission payload with it! Who’s watching with us at midnight?

#TEMPO

The stage is set for the launch carrying #TEMPO , which will help us study what's in the air we breathe. TEMPO Mission, a collaboration with our Center for Astrophysics | Harvard & Smithsonian, will be the first space-based instrument that can measure North American air quality hourly.

Our TEMPO Mission instrument is packed up and READY FOR LAUNCH. T-minus 8 hours (or so) until liftoff!

#TEMPO

In 1848, to understand the weather, the Smithsonian distributed monitoring equipment to volunteers across the U.S. This system gave rise to what we now know as the National Weather Service.

This week, we begin tackling a new challenge—monitoring pollution across the continent.

The TEMPO mission is nothing short of amazing. The size of a washing machine, it will be the first space-based instrument that can measure North American air quality hourly down to the ZIP code level. Image credit: Ball Aerospace

Apps on our phones tell us exactly when it will rain. Soon, we'll measure and predict the movement of air pollutants with the same precision with Center for Astrophysics | Harvard & Smithsonian and NASA Langley Research Center's TEMPO Mission, hitched to satellite Intelsat 40e. Image credit: Maxar

The TEMPO Mission crew, which includes members of NASA Langley Research Center and @CenterforAstro, has begun to gather in Cape Canaveral, Florida!

Let the countdown clocks begin! ⌛🚀
