Phoenix Logs/The Ark/Henry Lamb Research Outpost

The Henry Lamb Research outpost was the base of a UNSC scientific research

expedition to learn about the Ark, both in the interest of scientific advancement

and self-preservation from future Halo threats.

The expedition was spurred on by the re-activation of the existing Halo array in

2555 by the Ark's rampant Monitor, Tragic Solitude. A team travelled to the Ark

and stopped Tragic Solitude's plan to aggressively mine the Earth for materials

to rebuild the Ark, which had been damaged as a result of the battle that

ended the Human-Covenant War.

In 2557, a new team travelled through the portal in

New Mombasa in their ship

Eden Rising to set up base and activate dormant Retriever Sentinels in order to

start repairing the Ark. These researchers established an outpost expansion in February of

2558. In October of that year, the portal back to Earth closed,

followed shortly thereafter by the arrival of the Banished fleet. The base and it's

outlying facilities were all razed by the Banished attack.
