*Note: Since the satellite was deployed from the ISS, the alphanumeric COSPAR ID for SpinSat is 1998-067FL. Due to the 7-digit restriction for numeric translation of the COSPAR ID for the ILRS, the last two digits of the ID were designated as the year of the satellite's deployment (the ILRS will not be tasked to support any additional targets deployed from the ISS in 2014). Therefore the ILRS COSPAR ID has been set to 9806714.
