Deep Space 1 ( [Deep Space One] , "Far Space-1") is an experimental automatic interplanetary station (AMS) launched on October 24, 1998 by the Delta-2 launch vehicle as part of NASA 's New Millennium program. The main goal of the flight was to test twelve samples of the latest technologies that can significantly reduce the cost and risks of space projects [1] .

These samples included:
- An ionic engine of an electrostatic type ( ionized gas accelerates in an electrostatic field , creating jet propulsion ).
- Autonav is an autonomous navigation system that minimizes the need to adjust the movement of the device from the Earth, and is also capable of pointing the probe’s photo equipment to the target.
- Remote agent - software capable of self-testing and self-healing after failures.
- SDST ( Small, Deep-Space Transponder ) is a miniaturized long-distance radio communication system.
- MICAS ( Miniature Integrated Camera And Spectrometer ) is a small-sized, lightweight video system that combines a digital camera and a spectrometer .
- PEPE ( Plasma Experiment for Planetary Exploration ) is an integrated array of scientific tools for studying cosmic plasma , solar wind , electromagnetic fields and charged particles .
- SCARLET ( Solar Concentrator Array of Refractive Linear Element Technologies ) - lightweight and efficient solar panels .
- The Beacon Monitor experiment - the device sent signals only about its general condition, reducing the cost of ground operations [2] .
The device “Deep Space 1” successfully fulfilled the main goal of the flight and began to perform additional tasks: approaching the asteroid Braille and comet Borelli , transferring to Earth a significant amount of valuable scientific data and images. The program "Deep Space 1" was declared completed on December 18, 2001 [3] .
Technologies
Developed by NASA's Jet Propulsion Laboratory , Autonav’s autonomous navigation system works with images of famous bright asteroids . Asteroids in the inner part of the solar system move relative to other bodies with known and predictable speeds. Therefore, the spacecraft can determine their relative position by tracking such asteroids against the background of stars, which, in the used time scale, are considered motionless. Two or more asteroids allow the device to calculate its position using triangulation ; two or more positions in time allow the spacecraft to determine its trajectory. The status of the spacecraft is monitored by its interaction with the transmitters of the Deep Space Network (DSN), acting back to the Global Positioning System (GPS). However, DSN tracking requires a lot of trained operators, and the DSN is overloaded because it is used as a communications network . Using Autonav reduces mission costs and DSN requirements [4] [5] .
Autonav autonomous navigation system can be used in the opposite direction, to track the location of bodies relative to the spacecraft. This is used to target research tools. A very rough determination of the location of the target has been included in the apparatus program. After the initial setup, Autonav holds the object in the field of view, simultaneously controlling the position of the spacecraft. [4] The next spacecraft to use Autonav was Deep Impact [6] .
