We are sad to learn of the loss of our friend Brig. Gen. Charles McGee. We have been lucky to know and work with General McGee as he shared with our visitors the role he played as a Tuskegee Airman, breaking racial barriers and helping to win World War II.

#TDIH in 2009: The Ares I-X rocket lifted off on a test flight. At 327-feet tall, the test vehicle produced 2.6 million pounds of thrust to accelerate the rocket to Mach 4.76, just shy of hypersonic speed. This illustration from @NASA breaks down how all of that works.

Today in 1968, Wally Schirra, Donn Eisele, and Walter Cunningham splashed down in the Atlantic in the Apollo 7 command module, ending a successful mission: https://t.co/ee7MeCSTuh

Infrared Dawn: After years of delay and frustration, the James Webb Space Telescope is at last on target to launch in December. https://t.co/zk9q9n6Y54

💎 Lights. Camera. Lucy. The stage is set for our #LucyMission to launch to the ancient Trojan asteroids on Oct. 16. • Live coverage at 5am ET (09:00 UTC). • Liftoff targeted for 5:34am ET (09:34 UTC). Watch with us here and on NASA TV: https://t.co/z1RgZwQkWS

#TDIH in 2012: Felix Baumgartner became the first person to break the speed of sound in free fall. The capsule and pressure suit from Baumgartner's jump are part of the Air and Space collection. #IdeasThatDefy

Venetian Sight: The last probe to land on it lasted only two hours, but the planet nearest Earth has answers we want. So there’s a plan afoot to send a new lander to this world of hellish heat, crushing barometric pressure, and acidic atmosphere. https://t.co/gJ8UBE15oR

Sounding on Empty: There’s a new way to alert airplane pilots that they’re running out of gas. The technology, called modal propellant gauging (MPG), uses sound frequencies to determine fuel levels. https://t.co/lJBrkcQZy3
