 * Lieutenant Commander Jameson Locke's special operations team arrives at Misriah Armory at Eos Chasma on Mars. Locke reviews ONI Eyes files procured from Sedra.
 * Late in the year an automated UNSC scout vehicle, Recon-14, begins transmitting from Alpha Shard, piquing the interests of the Office of Naval Intelligence. The probe continues to document the surface of the ring's fragment, reporting all noted anomalies to ONI. These transmissions are analyzed by several ONI specialists, including Doctor Madeline Tress. Recon-14 detects a group of Thanolekgolo eels below the shard's surface. When the probe ventures to investigate the eels, the abnormally aggressive Lekgolo attack it. The heavily damaged Recon-14 succeeds in transmitting its final recordings to ONI before being destroyed by the Thanolekgolo.
