## FAQs
### Q: What was the primary purpose of Explorer 35?
A: Explorer 35 was a space probe designed for interplanetary monitoring. As an unmanned robotic spacecraft, its mission was to explore outer space and gather data beyond the immediate orbit of Earth.

### Q: What launch system was used for Explorer 35?
A: The probe was launched using the Thor-Delta, an American expendable launch system. It was deployed from Cape Canaveral Space Launch Complex 17.

### Q: What are the different names for Explorer 35?
A: Explorer 35 is known by several technical aliases, including IMP-E, AIMP-2, Anchored IMP-2, and Interplanetary Monitoring Platform-E.

### Q: How long did Explorer 35 remain active?
A: The probe was launched in July 1967. While some records indicate orbit decay in 1970, significant mission occurrences are documented through June 24, 1973.

## Why It Matters
Explorer 35 represents a key component of NASA's early efforts to monitor the interplanetary environment using robotic explorers. As part of the Interplanetary Monitoring Platform (IMP) program, it contributed to the scientific understanding of space physics outside of Earth's orbit. The mission utilized the Thor-Delta launch system, highlighting the reliability of American expendable launch vehicles during the late 1960s. Its designation as "Anchored IMP-2" (AIMP-2) signifies its role in a specific class of probes intended to study the space environment from a stable vantage point. The mission's data collection period, which extended into the early 1970s, provided researchers with a multi-year window into interplanetary conditions, bridging the gap between earlier satellite missions and more advanced deep-space exploration.

## Notable For
- **IMP Series Membership:** Specifically designated as IMP-E, it was a core part of the Interplanetary Monitoring Platform program.
- **Extended Mission Duration:** Recorded significant mission occurrences through June 1973, several years after its initial 1967 launch.
- **AIMP Designation:** Known as Anchored IMP-2, distinguishing it as a specialized robotic explorer within the Explorer program.
- **Launch Heritage:** Deployed from the historic Cape Canaveral Space Launch Complex 17 using the Thor-Delta rocket system.

## Body

### Mission Overview
Explorer 35 was launched on July 19, 1967, as an unmanned robotic spacecraft. Unlike standard satellites that orbit the Earth, Explorer 35 was classified as a space probe, a designation for craft that explore further into outer space. It is identified by the Satellite Catalog Number 02884 and COSPAR ID 1967-070A.

### Technical Specifications and Launch
The spacecraft was launched from Cape Canaveral Space Launch Complex 17. The mission utilized the Thor-Delta launch vehicle, an American expendable launch system. Explorer 35 is also referred to by several technical aliases:
*   **IMP-E:** Interplanetary Monitoring Platform-E
*   **AIMP-2:** Anchored IMP-2
*   **Anchored IMP-2**

### Mission Timeline
*   **Launch:** July 19, 1967
*   **Orbit Decay:** Records indicate a time of object orbit decay in 1970.
*   **Significant Occurrence:** A final significant occurrence for the craft is noted on June 24, 1973.

### Program Context
Within the sequence of NASA missions, Explorer 35 is situated between GEOS-B artificial satellites. It served as a specialized tool for interplanetary monitoring, contributing to the broader "Explorer" program's goal of robotic space exploration. The probe's data is cataloged under NSSDCA ID 1967-070A and is recognized in the Wolfram Language as Entity "02884".
