January 1978: NASA announced 35 new astronaut candidates! This class, otherwise known as the "Thirty-Five New Guys," included a number of milestones; it was the first to include women, African Americans, and Asian Americans in the program. https://t.co/PKSMjyrQKm

Is it a bird? No! A plane? Yes! It’s the first non-stop, around-the-world jet flight! The first jets to circle the earth were three B-52Bs that landed in California #OTD in 1957. The jets were refueled mid-flight and flew for 45 hours and 19 minutes. Image: @usairforce https://t.co/70O7pfhKgk

#HappyBirthday to astronaut Jeff Williams (@Astro_Jeff), who is 63 today! Williams has logged more than 534 days in space including 32 hours in spacewalks, and 3,100 hours in more than 50 different aircraft. Wishing this astronaut many more rotations around the sun. ☀️ 🚀 https://t.co/w7kA0GcblC

#OTD in 1976, Helios 2 launched on its mission to study the sun. NASA provided the launch vehicle while West Germany provided the probe itself. You can learn more about Helios 2 and other spacecraft here: https://t.co/C54sU52dOs https://t.co/KtLPyXjXCA

#OTD in 2006, NASA's probe Stardust returned comet and intersteller dust samples to Earth, completing the first deep-space sample-return mission. Stardust returned particles from the Comet Wild-2 and is likely to have collected particles originating beyond our solar system. https://t.co/tTZhS6JULc

#OTD in 2005, the @ESA's Huygens probe landed on Saturn's moon, Titan, after its release from @CassiniSaturn. Huygens is the only spacecraft to have soft-landed in the outer solar system and holds the record for the most distant landing from Earth. https://t.co/HPGd7Qh6Eg

Happy #birthday to Astronaut Shannon Lucid, born #OTD in 1943. In 1996, she spent 188 days in space mostly aboard the space station Mir, at the time breaking the record for longest spaceflight by an American. She's pictured here exercising on Mir's treadmill. https://t.co/68IQ4PoYgL

#OTD in 2008, the Messenger spacecraft made the first of its three Mercury flybys. On this flyby, it made its closest approach with Mercury at just 124 miles (~200 km) above the planet's surface. https://t.co/gqooDqO0Ky

#OTD in 2016, NASA's Juno spacecraft, en route to Jupiter, became humanity's most distant solar-powered spacecraft, about 493 million miles (793 million kilometers) from the sun. The record was previously held by the @esa's Rosetta spacecraft, which had visited a comet in 2012. https://t.co/DFGlEIwbFN

#OTD in 1969, after visiting the Department of State in DC, being celebrated with a ticker-tape parade in NYC, and enjoying the Super Bowl in Miami, the Apollo 8 astronauts Borman, Lovell, and Anders were welcomed home in Houston by a grand parade. https://t.co/09FgHCJi3c

#OTD in 1997, NASA announced the discovery of 3 black holes in the center of 3 galaxies. The discovery, enabled by @NASAHubble, indicated that all galaxies may have a central black hole. https://t.co/QlPBR0CXmP https://t.co/pN4xl0i2Rs

#OTD in 2015, the SpaceX ISS resupply spacecraft, CRS-5, was successfully captured with the @Space_Station's robotic arm controlled by NASA Astronaut Barry Wilmore and ESA Astronaut @AstroSamantha. https://t.co/q2nvFZcqs2

#OTD in 2005, Deep Impact launched on its mission to study comet composition. Upon reaching comet Tempel 1, it released an impactor spacecraft which generated an immense flash of light upon collision, as captured below. https://t.co/2ItFGG429L

#OTD in 1820, the Royal Astronomical Society (@RoyalAstroSoc) was conceived in a London tavern. Orginally known as the "Astronomical Society of London'", the RAS is a private society and charity dedicated to the study of astronomy, solar-system science, and geophysics. https://t.co/jTgKGCW4n3

In January 1942, Pan Am Pilot Robert Ford completed the first around the world flight by a commercial airliner. Stranded in the Pacific after the attack on Pearl Harbor, he was ordered to reach NYC by flying westward. https://t.co/qMIyX7M7dg Image: @airandspace https://t.co/TnqHdxkN0h

On this day in 2000, the SOHO spacecraft captured this large, twirling solar prominence. Prominences are huge clouds of relatively cool, dense plasma suspended in the Sun’s hot, thin corona. They can sometimes erupt and escape the Sun’s atmosphere. https://t.co/a1QQeCxXOp

"Darkness cannot drive out darkness, only light can do that. Hate cannot drive out hate, only love can do that." — Dr. Martin Luther King Jr. Today we honor his legacy with this stunning image of Atlanta, #MLK's birthplace, alight amidst the dark of night. https://t.co/ryrviVnBX5

It's #MoonCrushMonday, and we're marveling at the incredible views of the Moon featured in the @NatPhilharmonic's Music That Travels Through Space concert. #ObserveTheMoon Marvel with us here: https://t.co/xo6IKA2Ehw https://t.co/hE9XuD3q77

A new blog analyzes image composites of two flyby views of Mercury from the MESSENGER spacecraft and other data. Could it be that the planet has not cooled and shrunken as much as previously thought? Read now: https://t.co/imrcJDX6Ol https://t.co/Smz2v60DR3

Tomorrow's the day! We're test-firing the @NASA_SLS core stage for #Artemis I at @NASAStennis—live coverage begins at 3:20 PM CT Saturday, streaming on social media and @NASA TV >> https://t.co/ZbNtjELj5l @NASAArtemis https://t.co/zyFnbAfzJO

More than 20 years ago, Sergei Krikalev arrived at the @Space_Station with his crewmates to begin an unbroken streak of human presence in space. Krikalev recounts the mission and his career on this week's "Houston We Have a Podcast." https://t.co/kNiQkgsPaw https://t.co/AS6dxIDwy8

40 years ago, the new year of 1981 opened with major milestones for STS-1, the space shuttle Columbia, and the crew as teams prepare for the April 1981 launch. 📰 https://t.co/YKHqh3msod https://t.co/2LIzoTVMw3

Whoa... much better. A flaw in Hubble's mirror meant that the telescope first looked to the universe with blurry vision. But #OTD in 1994, @NASA announced that new optics installed during the first servicing mission to Hubble had solved the problem: https://t.co/T5dJnKu7aK https://t.co/GZOUVxGPks

50 years ago this week, the @NASA_Astronauts of Apollo 14 were preparing to lift off for the Moon >> https://t.co/ad17cjx64r #Apollo50th @NASAhistory https://t.co/kv5iX7rAFJ

We remember Dr. George Carruthers, who passed away Dec. 26. During his career at the U.S. Naval Research Laboratory, Dr. Carruthers invented the first Moon-based astronomy observatory, which was placed by Apollo 16 astronauts on the lunar surface: https://t.co/ZtQWGHxJbl https://t.co/7oo7ON5BpB

Apollo 8 concluded a successful mission that took astronauts to lunar orbit and back for the first time, when it splashed down in the Pacific Ocean, today in 1968. More on Apollo 8: https://t.co/1YObsaWxBa https://t.co/P1v6Wq783f
