## Why It Matters
Atlas V 411 represents a critical capability in U.S. space launch infrastructure, providing reliable access to space for both scientific and national security missions. As a variant of the Atlas V family, it offers specific performance characteristics that make it suitable for medium-lift payloads requiring particular orbital insertion profiles. The rocket has played important roles in advancing space science through missions like OSIRIS-REx, which returned samples from asteroid Bennu, and Solar Orbiter, which studies the Sun. For national security, Atlas V 411 has launched reconnaissance and early warning satellites that are vital to U.S. defense capabilities. Its reliability and versatility have made it a workhorse for U.S. space operations over multiple years, supporting both government and commercial customers with a proven track record of successful launches.

## Notable For
- Launching NASA's OSIRIS-REx mission, which successfully returned asteroid samples to Earth
- Supporting U.S. military space capabilities through launches of reconnaissance and early warning satellites
- Providing launch services for international scientific missions like ESA's Solar Orbiter
- Being part of the Atlas V family with over 80 successful launches since its introduction
- Offering specific performance characteristics for medium-lift payload requirements

## Body
### Technical Configuration
Atlas V 411 features a specific configuration within the Atlas V family. The numerical designation follows ULA's standard nomenclature where the first digit (4) indicates a 4-meter payload fairing, the second digit (1) represents a single solid rocket booster, and the third digit (1) shows a single-engine Centaur upper stage.

### Launch History
The rocket has been used for multiple launches across different mission types. Notable launches include the OSIRIS-REx mission in September 2016, which sent a spacecraft to asteroid Bennu to collect samples and return them to Earth. The rocket has also launched military satellites including early warning systems and reconnaissance platforms for the National Reconnaissance Office.

### Performance Characteristics
As a medium-lift vehicle, Atlas V 411 is designed to place payloads into various orbits including low Earth orbit, geosynchronous transfer orbit, and escape trajectories for planetary missions. The single solid rocket booster provides additional thrust during the initial phase of flight, while the Centaur upper stage with its single RL10 engine provides precise orbital insertion capabilities.

### Relationship to Atlas V Family
Atlas V 411 is one of several Atlas V configurations, each optimized for different payload sizes and mission requirements. The Atlas V family as a whole has become one of the most reliable launch vehicles in operation, with a strong track record supporting both government and commercial space access needs.
