The subroutine SUBSTRING extracts characters from a given string.

For example, SUBSTRING(3, 6, 'TELEMETRY') would return 'EMET'.

Figure 1 shows values assigned to four variables in a spacecraft control system:

mission ← 'Artemis-III'
status ← 'ORBIT_INSERTION'
telemetry ← 'ALT-402km-VEL-7.8'
payload ← 'SPECTROMETER_A'

The variable x is assigned a value using the statement:

$$x\leftarrow SUBSTRING(4,9,status)$$

Using Figure 1, what is the value of x?
