Just a few more minutes in today's #MercuryTransit ! Watch Mercury complete its journey across the Sun through the eyes of our Solar Dynamics Observatory satellite ➡️ . SDO keeps a constant eye on the Sun, so it has a prime view for transits like this! 🛰☀️

Science data from #ParkerSolarProbe 's first two solar encounters is now available to the public! 📈🛰 Details: 📷 This image was captured by the spacecraft's WISPR instrument in November 2018, during the mission's first solar flyby.

This past winter, a science team led by NASA traveled to a tiny town off the coast of Norway to launch a sounding rocket mission from the world’s northernmost rocket range. Follow their journey to capture unique scientific data under extreme conditions:

Ny-Ålesund falls directly below Earth’s magnetic cusp once a day, so particles have a direct path between our planet and space, funneled by Earth’s magnetic field — making this spot uniquely suited for studying how our planet’s oxygen is slowly leaking into space.

Getting an up-close look at this slow leak — a natural process that will take billions of years — and the aurora-related mechanisms that drive it is only possible by launching small, suborbital rockets as it’s happening. That’s how the VISIONS-2 mission was born.

Want to learn more about this extreme science? Hear from this mission’s lead researcher and other sounding rocket scientists about how these tiny rockets enable cutting-edge science: 🗓️ Monday, Nov. 18 🕑 2pm ET / 11am PT ❓ #askNASA

Mercury transits are relatively rare — the next one isn't until 2032! Watch Mercury make its trek across the Sun today at 🛰⚫️☀️

No #eclipse  glasses? You can still watch #Eclipse2017  by making your own pinhole projector!

Happy Halloween! Our sun looks a bit like a spooky jack-o'-lantern in this image from sun-watching spacecraft SDO:
