(Radio Iowa) – A Midwestern kid who loved “Star Trek” grew up to be a principal mechanical engineer for NASA who’s worked on every Mars mission since Pathfinder, which took the first rover to the Red Planet in 1996. Kobie Boykins will be in central Iowa this week to tell his personal story, and to discuss the next big project for NASA’s Jet Propulsion Laboratory, in a lecture he’s calling: “Beyond Earth: The Quest for Life on an Icy Moon.”

“A mission that we’re going to launch later this year called Europa Clipper, to Jupiter, and while we’re at Jupiter, we’re going to be exploring the icy moon of Jupiter called Europa,” Boykins says. “Mostly, we’re going to be talking about the engineering that went into building this vehicle, some of the decisions that went on, and talk about some of the problems and how we fixed them.” As a boy in Omaha, Boykins says he used to sit on his rooftop and gaze up at the stars. He adored “Star Trek: The Next Generation,” particularly the character Geordi La Forge, chief engineer on the starship, Enterprise. Boykins says he always wanted to be the person who was asked to fix things.

“I thought it was very interesting to figure out how things work and then be asked, ‘Hey, how does that work and what would you do? How would you make it better? How would you build that?'” Boykins says. “I think it was probably in fifth grade where I had a teacher that sort of connected with me in some way — magic, I don’t know — that put me on a path to say, ‘Hey, you could be whatever you want,’ and at that time, I wanted to be Geordi La Forge.” In addition to the Pathfinder mission, Kobie designed the solar arrays that powered the Mars rovers Spirit and Opportunity. He also helped build the seven-foot-tall rover Curiosity, which carried 10 different tools, 17 cameras and a laser. While placing robotic rovers on the Martian surface is a tremendous accomplishment, many others (including a few billionaires) are focused on landing -humans- on that dusty red planet, 140-million miles away. Does he see that happening anytime soon?

“We have the technology to send a human being to Mars today. The bigger problem is that the technology is not there to make sure that the human beings stay alive. That’s part of the struggle,” Boykins says. “Will it happen within the next decade or the next two? I think that’s approximately the scale that we’re talking about.” Boykins is chief engineer on NASA’s Europa Clipper mission, and he’s been awarded NASA’s Exceptional Service Medal, one of the highest honors given to NASA employees and contractors. Still, after all his successes with rovers on Mars, Boykins says his biggest thrill is when he learns he’s inspired someone else.

“That’s sort of the legacy for me,” Boykins says, “that I have people that were students or individuals that were looking for what their career might be, and they heard me give a talk about how much I love being able to do this work and this job and they decided, ‘Yeah, this is the path I want to be on,’ and they ended up in the same path, or in the same place that I am. Those are amazing stories to me.” Boykins will appear Thursday as part of the Explorer Series at the Des Moines Civic Center.

(Radio Iowa) – A professor at Des Moines University is doing a national research project that at first glance seems like a segment of This Old House. Anatomy professor, Heather Garvin, is studying the cutting characteristics of saws, but her focus is how the saws cut through human bones, not wood. “And the reason we’re looking at this is that we do get cases of dismemberment in the forensic anthropology, world,” she says. “And what we try to do for law enforcement and for investigators, is to give them as much information as we can about the tool that was used.” Garvin is the only board certified forensic anthropologist in the state of Iowa and one of only about 120 of us throughout the country. Garvin says the work focuses on identifying the type of saw used in a crime to help investigators.

“We can’t say that it is this one specific saw, the saw that was used, but we can say what type of saw and the characteristics of a saw,” Garvin says. “So for example, powered saws will leave lighter, wider cuts in the bone than hand saws.” Garvin says they can’t be like ballistic experts who can link a bullet to the specific gun it was fired from, but they hope to identify different marks left by the teeth of saw blades. “If anyone works in carpentry, they’ll realize there’s there’s a large variation of saws out there where you have different teeth per inch different size teeth, different materials, whether they’re cutting like a knife, or if they’re ripping through the material,” Garvin says. “And so we’re trying to figure out what characteristics those marks in the bone correlate with.” She says other individuals in the project will be collecting data blindly so they won’t know what saws made the cuts and they can do a statistical analyses to see if they can use the marks on the bone to identify the type of saw. Garvin says dismembering a corpse after a murder isn’t something that’s all that common in Iowa.

“But in other areas of the country where you have very urban areas and it’s harder to dispose of a body during a criminal act, you do get a higher number of dismemberment’s, because that makes it easier for them to hide and then dispose of human remains,” she says. Garvin won a grant from the National Institute of Justice to do the saw research. She says they use a microscope with a camera to study the cut marks, and may eventually use micro C-T scan that can put together x-rays in a sort of 3-D model.

“It’s a little harder with cut marks, because what we’re dealing with really doesn’t have much relief. You know, these are tiny scratches in the bone that we’re looking at,” Garvin says. “But I think as technology advances and it becomes more sensitive with that micro C-T, that might be an avenue as well.” It might seem kind of gruesome to do this research on human bones, but Garvin says she can block that out and see it as important scientific work.

“The thing is, someone has to do it and by doing it, you’re helping loved ones have a family member right? They may have a missing family member, they don’t know where they are, you’re able to identify those remains and bring some closure to that family,” Garvin says. She says it can also help with providing the evidence that brings justice for the person who was killed.

(Radio Iowa) – A key lawmaker says the Senate may soon debate what has turned out to be the central issue of the 2024 legislative session. Three weeks ago, the Iowa House passed a bill to maintain Area Education Agency special education services for students with disabilities, but make changes in other A-E-A functions. The governor has called for giving schools the option of keeping A-E-A services for students with disabilities or, instead, hiring private companies or local staff to do it. Senate Majority Leader Jack Whitver says Senate Republicans are close to unveiling their own plan.

The plan House Republicans passed calls for a study of the A-E-As. That’s not part of the plan Senate Republicans are developing.

Whitver says Senate Republicans will draft a bill about A-E-A changes that includes an increase in the minimum salary for first year teachers. That was the governor’s approach. Last month, a House bill raising teacher salaries and pay for other school staff passed 93-to-one.

House Speaker Pat Grassley says because of budget implications, the decisions on teacher pay and the general level of state spending on public and private schools as well as the future of A-E-As are all related.

A recent Des Moines Register/Mediacom “Iowa Poll” found 56 percent of Iowans have a favorable view of Area Education Agencies. That rating goes a bit higher — to 59 percent — among Iowa parents with school-aged children.
