We’re excited to host @VP Pence & Administrator @JimBridenstine tomorrow for a tour of our world-class research center! Tune in to NASA TV at 11:45am PT for live remarks about our program & plans to return astronauts to the Moon in 2024. Details: t.co/yqSQtPKcwA t.co/AOk8elS8yF

It's harvest time on @Space_Station! 🍃 Astronauts have been cultivating fresh mustard greens in the station's Veggie facility. Today, they cut some of the leaves — half go in freezers for later analysis on Earth, and half are for the crew to taste. More: t.co/91jf4riQ30 t.co/kt4Ca3ZSMO

In California, Utah & New Jersey, mosquito control agencies use @NASAEarth data to keep new infestations at bay. It's used in a website that helps public health officials monitor and respond to potential outbreaks of mosquito-borne diseases. Details: t.co/443DPk5ziA t.co/Ibf1TDrikR

.@NASA_Technology in your life: We developed new pressure vessels because we needed stronger, lighter tanks to carry liquids & gas to space. Today, this tech is used widely, including in firefighting equipment, in scuba gear, and even in paintball. More: t.co/T5OcrdLoqe t.co/Uc0Ysp8rtp

Progress toward the launch of I — our @NASA_Orion 🛰️ has completed final assembly and systems testing. The @NASA_SLS 🚀 core stage is nearing completion, as technicians attach the RS-25 engines to propulsion and avionics systems. About Artemis: t.co/ZWo5wJkX76 t.co/kVkc9y1hWs

Tomorrow is the 50th anniversary of the launch of ! For the long journey, the astronauts needed some sustenance, so here’s a suit tech putting a sandwich in Pete Conrad’s pocket during suit-up for launch. t.co/O9eSIBSfJv

As our Parker Solar Probe orbits the Sun, its instruments capture data to help solve mysteries of the solar atmosphere.
Data from the mission's first close solar encounters has now been released to the public — for everyone to analyze and use. ☀️📈 More: t.co/cF4HC5kH34 t.co/hcvfokoCsK

Our rover will launch next July and land in Mars' Jezero Crater in Feb., 2021. Scientists have discovered deposits of carbonates in the crater, identifying one of the best places for the rover to search for signs of ancient life. Details: t.co/czh8Jmjdoh t.co/902irllJAf

Have plans on Dec. 9-10? 📅

We’re inviting social media users to apply to visit our rocket factory in New Orleans, see the @NASA_SLS rocket core stage assembled with all four RS-25 engines and learn about our program to explore the Moon. Details: t.co/5IswTx1ifB t.co/hYKnDnwKU3

What caused the brightest X-ray burst ever seen by our @NASAUniverse NICER telescope? 🤔
A massive thermonuclear flash from the remains of a star that exploded as a supernova. The explosion released as much energy in 20 seconds as the Sun does in 10 days.

'Arrokoth': a Native American term meaning “sky” in the Powhatan/Algonquian language. With consent from Powhatan Tribal elders and representatives, it's now the official name for the Kuiper Belt object visited by @NASANewHorizons. About today's ceremony: t.co/1jp3Y2CvNX t.co/ni7TGq8zYE

Over 6 years, a chemistry lab inside the belly of @MarsCuriosity has inhaled Martian air & analyzed its composition. Scientists found that the nitrogen & argon follow a predictable seasonal pattern — but not oxygen. Learn about the newest Martian mystery: t.co/Pf3kdsgC8E t.co/yy43UdeuSY

LIVE: The second briefing on upcoming spacewalks by @AstroDrewMorgan & @astro_luca to repair the Alpha Magnetic Spectrometer on @Space_Station. Learn about the specialized tools used for this complex repair and the goals of each spacewalk.

What is Gateway 🛰️? This lunar outpost will be where our astronauts live & work around the Moon, just about a 5-day, 250,000-mile commute from Earth.

What questions do you have about Gateway? Send them & check back for responses! More: t.co/2ZSdkvwrCq t.co/NYtCtyqQeg

Q: What did Mercury say when it was asked to line up between Earth & the Sun?
A: I'll pass! 😎

We witnessed a rare treat during today's , which only happens ~13 times a century! Revel in the views captured our @NASASun-observing satellite: t.co/Wm7TYlNSeX t.co/UqhYHTpAQm

The world’s reaction was as humbling as its views. Inspired that a day doing our job could mean the honor of conducting the first , here is a glimpse of that moment and what it meant to us.

That's all, folks! Mercury has left the disk of the Sun, completing the transit. The next Mercury transit is in 2032 — so in the meantime, you can read up on @NASAUniverse's TESS mission, which uses transits in other star systems to look for exoplanets! t.co/2NlnHKzBFn t.co/zRLdYnHiaz

Just a few more minutes in today's ! Watch Mercury complete its journey across the Sun through the eyes of our Solar Dynamics Observatory satellite ➡️ t.co/5OFdcyOFJ8. SDO keeps a constant eye on the Sun, so it has a prime view for transits like this! 🛰☀️ t.co/QuCxZL6u1X
