DeHate will use a solid-fuel propellant, like the space shuttle boosters, but a lot less of it.
"Instead of going mach five (i.e., five times the speed of sound), it's only going to go 500 miles per hour," he said.
Robinson's ashes will be sealed inside a metal case that DeHate machined out of solid aluminum. After the rocket reaches its highest point, the box will be carried down by a parachute released by electronics the Salem man designed.
As of midweek, DeHate had worked out every detail for the launch — except one.
"I'm not certain if it's legal to scatter the ashes," he said.
