## Summary  
Biosatellite 3 was a NASA-operated biosatellite launched in 1969 to study the effects of spaceflight on living organisms, specifically a male pig-tailed monkey named Bonnie. It was part of the Biosatellite program and marked the final mission in the series. The mission ended prematurely due to the primate's deteriorating health, but it provided valuable data on biological responses to space conditions.

## Key Facts  
- **Launch Date**: June 29, 1969, at 03:15:59 UTC from Cape Canaveral Space Launch Complex 17A.  
- **Landing Date**: July 7, 1969, splashing down in the Pacific Ocean.  
- **Launch Vehicle**: Delta N (serial number 539/D070).  
- **Operator**: National Aeronautics and Space Administration (NASA).  
- **Mission Duration**: 8 days (cut short from the planned 30-day mission).  
- **Payload**: Carried a male pig-tailed monkey named Bonnie to study biological effects of spaceflight.  
- **Orbit**: Low Earth orbit.  
- **COSPAR ID**: 1969-056A.  
- **NSSDCA ID**: 1969-056A.  

## FAQs  
### Q: What was the purpose of Biosatellite 3?  
A: Biosatellite 3 aimed to study the physiological and behavioral effects of prolonged spaceflight on a primate, providing insights into human adaptability for future missions.  

### Q: Why did Biosatellite 3 end early?  
A: The mission was terminated after 8 days due to the declining health of the monkey, Bonnie, who experienced stress, weight loss, and elevated heart rate.  

### Q: What happened to the monkey after Biosatellite 3 landed?  
A: Bonnie died shortly after splashdown due to complications from dehydration and cardiac stress, but the data collected contributed to understanding spaceflight's biological impacts.  

## Why It Matters  
Biosatellite 3 was significant as NASA's first attempt to study a primate in space for an extended period, bridging gaps between earlier animal experiments and human spaceflight. Despite its premature end, the mission highlighted the challenges of maintaining biological health in microgravity, influencing later life-support systems and astronaut health protocols. The data underscored the need for better environmental controls and monitoring, shaping future missions like Skylab and the International Space Station.  

## Notable For  
- **First Primate Mission**: The only Biosatellite mission to carry a primate (Bonnie).  
- **Shortened Mission**: Originally planned for 30 days but aborted after 8 due to the subject's health.  
- **Critical Data**: Provided early evidence of spaceflight's physiological stress on higher mammals.  
- **Final Biosatellite**: Last mission in NASA's Biosatellite program.  

## Body  
### Mission Overview  
- Part of NASA's Biosatellite program, designed to study biological responses to spaceflight.  
- Launched on June 29, 1969, aboard a Delta N rocket.  

### Payload and Experiment  
- Carried Bonnie, a pig-tailed monkey, to monitor vital signs, behavior, and metabolic changes.  
- Equipped with sensors for heart rate, body temperature, and activity levels.  

### Mission Termination  
- Health issues forced an early landing on July 7, 1969.  
- Bonnie died post-recovery, but data on dehydration and stress proved valuable.  

### Legacy  
- Informed later NASA missions about life-support requirements.  
- Demonstrated the challenges of long-duration biological experiments in space.
