Progress M-39

 1998-031A


Spacecraft 238 was launched in May 1998 as Progress M-39 carrying the usual cargoes and a special request of fresh lemons, and a guitar, plus 15 Oriental newts and 80 snails for adaptation studies. It was intended to be the first Progress to lower Mir's orbit in preparation for deorbiting, but this was changed. Progress No. 238 carried an Energiya experiment for protein crystal growth to be recovered by Baturin in August.

After undocking in August, it led Mir by 6min 49s on 28 Aug before beginning rendezvous burns to redock.
