The JSpOC has mixed up the IDs of the satellites that were launched
from the ISS on February 28. Although we all know that LITUANICASAT 1
is object 39569, 1998-067EN, it is now indicated as 39571, 1998-067EQ.
This object 39571, ARDUSAT 2, is expected to decay on July 2. But
OSCAR 78 will probably decay in August.
