There is method to what might appear to be Cossman's madness. The expedition shown above, into what is known locally as "The Entrance to Hell," used GoPros and drones to produce a virtual, 3-D model of an active volcanic lava lake. And now the self-described "volcano diver" is descending into Nicaragua's Masaya Volcano, just outside Managua, in order to install some Wi-Fi.

Specifically, Cossman, working with General Electric and the Nicaraguan government, will, according to a report in The Verge, descend approximately 1,200 feet into the volcano's crater and set up about 80 wireless sensors that "will gather real-time data about Masaya's temperature, atmospheric pressure, gravity and the variety of different gasses like carbon dioxide and hydrogen sulfide." The data will then be uploaded to an open-source database called PreDix, which GE owns, where the volcano's behavior can be monitored 24/7.
There is no guarantee of success. Although Cossman naturally wears advanced protective clothing, the conditions remain highly dangerous and unpredictable. As he told Business Insider last year: "Cameras melt, your gas mask melts, even the gas masks that are designed to purify the air at that level of particulate matter, they can't. The lava is very unpredictable, you might be half way down and see it crust over, but then it builds up pressure and explodes, turns into this raging explosive force."
Only one of the drones that he used on that earlier expedition returned in working order.

Still, the incentive is strong. One of Nicaragua's most active volcanoes, Masaya most recently erupted in 2012.
In a post on GE's Facebook page, volcanologist Guillermo Caravantes said that, "We could potentially have millions of lives at risk. It could happen at any time and the problem is, we are not able to predict when this could happen."
Said Cossman to The Verge: "The goal is essentially to install all these sensors and create the most effective early warning system in the world."
