55 years ago today, the Apollo 11 rocket crawled along the three-and-a-half-mile journey to Launch Pad 39A.

The 363-foot-high space vehicle later launched Apollo 11 astronauts Neil A. Armstrong, Michael Collins and Edwin E. Aldrin Jr. on the first crewed lunar landing mission.

Congratulations Ed Dwight, the United States’ first Black astronaut candidate, on a successful mission aboard Blue Origin’s New Shepard NS-25

This week, we practiced #Artemis II lunar science, previewed a polar climate mission, and spotted a young star.

NASA, Boeing Space, and ULA are now are targeting no earlier than 3:09pm ET May 25 for the launch of the agency's Boeing Crew Flight Test mission.

Teams will use the additional time to finalize next steps that address a stable helium leak on the #Starliner service module.

Earlier this month, we experienced the strongest solar storm to reach Earth in two decades.

The Sun's solar flares gave us a brilliant light show of auroras—but also provided valuable data for our NASA Sun & Space scientists: go.nasa.gov/3K2lhpn

Did you see the aurora? 🤩

Citizen scientists with NASA’s Aurorasaurus project, which tracks aurora sightings, took these photos on May 10-11, 2024 during a geomagnetic storm that @noaa reports is the most extreme since 2003. go.nasa.gov/4blgYBg

Our experimental X-59 @NASAAero aircraft, which could pave the way for a new generation of quiet supersonic planes, just completed a key review on its path to first flight: go.nasa.gov/4asyB0K

Reaching the stars starts with our workforce!

For the 12th year in a row, we've been ranked by @PublicService as the best place to work in the federal government among large agencies.

Thank you to everyone who contributed in making NASA the #FedBPTW : go.nasa.gov/3V3AVaa

Welcome to the #Artemis Accords, Lithuania 🇱🇹

Lithuania became the 40th country to commit to the peaceful and safe exploration of space as we look ahead to the Moon, Mars, and beyond: go.nasa.gov/3ymarI2

LIVE: Hear from experts as we discuss the agency's PREFIRE mission, which will study heat loss from Earth's polar regions and provide information on our changing climate. The first of two small satellites is set to launch NET Wednesday, May 22. bit.ly/4bv3Byi

You're in for a ride! 🐴

When it comes to the Horsehead Nebula, multiple missions have taken the reins. From Euclid, to Hubble, and now Webb, we can learn more about our universe thanks to these amazing machines. More on Webb's contributions: go.nasa.gov/3JXCFLU

The Sun emitted a strong solar flare on May 14, 2024, peaking at 12:51pm ET. NASA’s Solar Dynamics Observatory captured an image of the event, which was classified as X8.7. go.nasa.gov/4aipKPf

NASA, Boeing Space, and ULA are now targeting no earlier than 4:43pm May 21 for the launch of the agency's Boeing Crew Flight Test mission.

On May 11, the ULA team successfully replaced a pressure regulation valve on the liquid oxygen tank on the Atlas V rocket’s Centaur

We will be discussing our PREFIRE mission, which aims to improve life on Earth and provide information on climate change by studying heat loss from Earth’s polar regions. Listen in at 3pm ET on May 15: go.nasa.gov/4dCWOV6

Creators, get those applications #ReadytoGOES ! You have until 3pm ET (1900 UTC) May 14 to apply to attend the #NASASocial for NOAA’s GOES-U satellite launch on June 25 at NASA's Kennedy Space Center. go.nasa.gov/4agb5Em

Congratulations to the class of 2024! 🎉🎓

You've accomplished so much and now it's time for your next chapter. As a graduation gift, recent astronaut graduates share their advice and encouragement for all of you taking off on your next big adventures.

15 years ago today, astronaut Mike Massimino wrote the first Tweet in space.

Here's to the many more we've shared since then—around the world and off it:

Have you seen the aurora this weekend?

Follow NASA Sun & Space to learn more about how it happens—and keep an eye on NOAA (and NOAA Space Weather Prediction Center) for the latest aurora updates. We'd love to see your favorite photos from the aurora, too!

Look how far we've come. Couldn’t have done it without you. 💚

On this #MothersDay , we're taking a look back at Mother Earth—and celebrating those that propel us further in our growth, inspire our curiosity, and challenge us to do better.

Why do we get auroras on Earth after eruptions occur on the Sun? A thread. 🧵
