EaglePicher marks success with return of asteroid samples

Sep. 25—Asteroid samples collected from deep space returned to Earth on Sunday — a mission that would not have been possible without the role of a Joplin company.

During a flyby of Earth, the Osiris-Rex spacecraft ejected a smaller capsule that parachuted safely to scientists in a Utah desert waiting to collect the material from the asteroid Bennu.

Because it is so old, Bennu could contain organic molecules similar to those that could have been involved with the start of life on Earth, according to scientists.

Power to reach Bennu came from one of Joplin's oldest and largest employers, EaglePicher.

The Delta V rocket, which launched the craft out of Earth's orbit in 2016, had between 10 and 14 of the company's silver-zinc batteries powering it.

The uncrewed Osiris-Rex spacecraft that collected the dust and rock samples from Bennu is powered by four EaglePicher batteries, according to Ron Nowlin, senior vice president of program management for the Joplin-based company. Two 28-volt, 30-amp lithium-ion batteries that are charged by the spacecraft's solar panels provide power to the primary spacecraft for communications, science experiments, photography and more.

Nowlin previously told the Globe that the company started this project a decade ago, and said the mission had been going on so long it is easy to forget that the spacecraft is still out there.

The sample capsule that reentered the atmosphere Sunday did so with electrical power also provided by EaglePicher. That secondary craft was powered by two of the company's 28-volt, 17-amp lithium batteries.

New ownership?

Going into space is nothing new for EaglePicher, which has been a source of batteries and power systems for satellites and space vehicles, crewed and uncrewed, since 1958 with Explorer I. What is changing for the company is possible new ownership.

Recently, a privately held Illinois company announced it has reached an agreement to acquire EaglePicher, which has just under 900 employees companywide, most in the Joplin area. EaglePicher has three plants in Joplin, as well as Seneca, a corporate office in St. Louis; a plant in Pittsburg, Kansas; and plants in Rhode Island and Massachusetts.

Tuthill Corp. said in a statement that the deal is expected to close in 2023, subject to regulatory approvals and other closing conditions. EaglePicher is currently owned by another Illinois company, GTCR, based in Chicago.

In a statement, Jay Tuthill, chairman of Tuthill, said: "It has taken 130 years for Tuthill to reach this place — a place where we are able to join forces with a company like EaglePicher. It has required the combined efforts of thousands of good people to make this possible. It's a personal thing for me. I come from a military family. I believe in a strong America. I'm thrilled to know that, through EaglePicher, Tuthill will now be a direct contributor to the defense, space and aviation industries that help to keep our country at the forefront."
