"During the almost 3 ½ minutes of weightlessness, Mike tossed out a handful of M&M’s (for his initials – picked up on a whim the morning of the flight) to watch them float as he raised the tail booms into the feathered position for its descent and enjoyed the view."

Space Shuttle Atlantis' twin white solid rocket boosters separate and jettison as planned two minutes into flight. Atlantis is delivering a new segment to the starboard side of the International Space Station's backbone, known as the truss. Three spacewalks are planned to install the S3_S4 truss segment, deploy a set of solar arrays and prepare them for operation. STS-117 is the 118th space shuttle flight, the 21st flight to the station, the 28th flight for Atlantis and the first of four flights planned for 2007.
Space shuttle Endeavour's external tank is jettisoned after the journey to orbit. The STS-126 mission will be the 124th space shuttle flight and the 27th flight to the International Space Station. The mission will feature four spacewalks and work that will prepare the space station to house six crew members for long- duration missions.

Audi S3 Sedan – Torque splitter – Animation
This animation shows the functionality of the torque splitter in the Audi S3 Sedan. This technology makes fully variable torque distribution between the rear wheels possible. The result is better stability, particularly on wet ground, and improved agility during fast cornering.
Audi S3 Sedan – Vehicle dynamics – Animation
This animation shows how in the Audi S3 Sedan the powertrain and the chassis provide first class driving dynamics.

The futuristic XB-70A was originally conceived in the 1950s as a high-altitude, nuclear strike bomber that could fly at Mach 3. The first XB-70A airplane continued to fly and generate valuable test data in the research program until it came to the museum in 1969.
Apollo 11 Moon Landing
Project Apollo 11
Video Date Created:1985-01-01
On July 16, 1969, the huge, 363-feet tall Saturn V rocket launches on the Apollo 11 mission from Pad A, Launch Complex 39, Kennedy Space Center, at 9:32 a.m. EDT. Onboard the Apollo 11 spacecraft are astronauts Neil A. Armstrong, commander; Michael Collins, command module pilot; and Edwin E. Aldrin Jr., lunar module pilot. Apollo 11 was the United States' first lunar landing mission. While astronauts Armstrong and Aldrin descended in the Lunar Module "Eagle" to explore the Sea of Tranquility region of the moon, astronaut Collins remained with the Command and Service Modules "Columbia" in lunar orbit.

Predictions of air pollution are created using complex models that combine information about weather and the emissions, transformation, and transport of chemical species and particles. The Goddard Earth Observing System Composition Forecasting (GEOS-CF) system is a research model maintained by NASA’s Global Modeling and Assimilation Office to help scientists understand the causes and impact of air pollution. It is one of the highest resolution and most detailed models of its kind in the world, made possible through ongoing collaborations between NASA and university scientists. GEOS-CF tracks the concentrations of hundreds of gas phase chemical species and dozens of types of particles characterized by their composition and size. It is used by a wide variety of stakeholders around the world to develop new methods for improving local predictions, understanding the impact of pollution on human health, and improving the quality of NASA satellite datasets.
Carbon Monoxide, a molecule comprised of one carbon and one oxygen atom, is a product of incomplete combustion. It is emitted from a variety of human activities involving vehicles, industry, and residential wood burning and from wildfires. In extremely high concentrations, carbon monoxide can interfere with the ability of blood to carry oxygen, causing fatigue, headaches, dizziness, and confusion. In many parts of the U.S. and Europe, levels have decreased substantially in recent decades due to improvements in vehicle technology and regulations aimed at limiting emissions. However, increases in the frequency, severity, and duration of wildfires are increasing emissions of carbon monoxide. Because of its relatively long lifetime in the atmosphere (about 2 months), it can be transported over long distances by weather systems, illustrating the global reach of air pollution and challenges that cannot be addressed through local action alone.

B-roll for media and public use. NASA’s Europa Clipper mission, scheduled to launch in October 2024, will conduct a detailed survey of Jupiter’s moon Europa to determine whether the icy moon could harbor conditions suitable for life. This reel includes clips showing the assembly and integration of various parts of the spacecraft within a clean room at NASA’s Jet Propulsion Laboratory.
The spacecraft, in orbit around Jupiter, will perform dozens of close flybys of Europa, soaring over a different location with each pass so that it eventually scans nearly the entire moon.
Europa Clipper will launch from NASA’s Kennedy Space Center in Florida.

This time-lapse shows a laser 3D printing process that fused metals together, layer-by-layer, to create the new alloy GRX-810. This alloy is an oxide dispersion strengthened alloy, which is great for building aerospace parts for high-temperature applications because they can withstand harsher conditions before reaching their breaking points.
The second qualification model of the P120C solid rocket motor, configured for Ariane 6, completed its hot firing on 7 October 2020 in a final test to prove its readiness for flight.
Depending on the configuration, two or four P120C motors, developed in Europe, will be strapped onto the sides of the future Ariane 6 launch vehicle as boosters for liftoff. The P120C will also be used as the first stage of Vega-C.
After it was fully loaded with 142 tonnes of fuel, the 13.5 m long and 3.4 m diameter motor was ignited to simulate liftoff and the first phase of flight.
The motor burned for 130 seconds and delivered a maximum thrust of about 4500kN. The test was performed at Europe’s Spaceport in French Guiana, and was completed with no anomalies.
"Who has ever seen a LOX/Kerosene liquid 🚀 engine with a blue plume 💎💎💎💎? Not only does it look spectacular, but it also serves as undeniable proof of the 99%+ combustion efficiency achieved in this test.
Enjoy this 3-minute, 20-second test of E-2, a mostly 3D-printed 22k lbf (10 tf) ORSC LOX/Kerosene liquid rocket engine. Nominal pressure: 100 bar; mixture ratio: 2.7. Recorded today at NASA Stennis, this test also secured the duration record for the test stand. E-2 is now available for sale to launch companies."
