A federal judge in Virginia has ruled that a salvage firm can retrieve the Marconi wireless telegraph machine that broadcast distress calls from the sinking Titanic ocean liner.
In an order released on Monday, US District Judge Rebecca Beach Smith agreed that the telegraph is historically and culturally important and could soon be lost within the rapidly decaying wreck site.
She wrote that recovering the telegraph "will contribute to the legacy left by the indelible loss of the Titanic, those who survived, and those who gave their lives in the sinking".
Ms Smith is the maritime jurist who presides over Titanic salvage matters from a federal court in Norfolk. Her ruling modifies a previous judge's order from the year 2000 that forbids cutting into the shipwreck or detaching any part of it.
Ms Smith's order is a big win for RMS Titanic Inc, the court-recognised salvor, or steward, of the Belfast-built liner's artefacts.
The firm recently emerged from bankruptcy and is under new ownership.
The National Oceanic and Atmospheric Administration, which represents the public's interest in the wreck site, fiercely opposes the mission, arguing that the telegraph is likely surrounded "by the mortal remains of more than 1,500 people" and should be left alone.
