As a part of Nationwide Geographic Stay, Chief Engineer Kobie Boykins of NASA’s Jet Propulsion Laboratory (JPL) has been touring the world of late. As a part of this system’s aim of getting featured audio system share their behind-the-scenes tales, Boykins has been showcasing the accomplishments of NASA’s Mars robotic exploration packages – of which he performed a significant function.
This week, his tour introduced him to my hometown, the place he delivered a presentation to a packed home on the Royal Theatre right here in of Victoria, BC. Titled “Exploring Mars”, Boykins shared private tales of what it was wish to be an integral a part of the crew that created the Sojourner, Spirit, Alternative, Curiosity and Mars 2020 rovers. I had the honour of attending the occasion, and having the ability to perform a little Q&A with him after the present.
In terms of the exploration of Mars, there are few extra certified than Boykins, whose work with NASA JPL goes again to the Mars Pathfinder mission of 1997. It was at the moment that Boykins, whereas nonetheless a university pupil, helped fabricate the cleats used on the Sojourner rover’s wheels. Since then, he has gone on to steer the crew that designed the photo voltaic arrays that powered the Spirit and Alternative rovers.
He and his design crew have been additionally accountable for growing the actuators on the Mars Curiosity rover and
In 2002, Boykins joined “Marsapalooza”, a crew of younger scientists who toured with the intention to consciousness of the Mars Exploration Challenge. In 2003, he turned a part of NASA’s M-Crew, which lectured nationally to college students concerning careers within the STEM fields. And by 2006, he
The presentation started in earnest with Boykins sharing anecdotes of what it’s wish to be an engineer engaged on a NASA mission and what impressed him to develop into a NASA engineer within the first place. As a local of Nebraska, Boykins grew up in an space the place there was little gentle air pollution. On a transparent night time, he and his sister would climb onto their roof to search for on the night time sky and ponder the probabilities.
The main focus then shifted to the exploration of Mars and a lesser-known side of issues. With a concentrate on two packages – the Mars Exploration Rover (Spirit and Alternative) and the Mars Science Laboratory (Curiosity and Mars 2020) – Boykins supplied a glimpse into what goes on behind the scenes at JPL and what it’s wish to be an engineer engaged on the robotic explorers.
This started with Boykins sharing official NASA animations of the Alternative and Curiosity rovers leaving Earth and journeying to Mars in 2003 and 2011. This included the launch aboard two multi-stage rockets (a ULA Delta II Heavy and an Atlas V, respectively), months of touring between the planets, after which managed landings involving parachutes and/or inflatable balls and
All through, he supplied a play-by-play of the know-how concerned, the in depth testing and planning that went into the launch, flight, touchdown, and deployment of every rover. As Boykins made clear in the course of the course of his presentation, a substantial period of time and preparation goes into essentially the most primary of actions, whether or not it’s attending to Mars or commencing science operations as soon as on the floor.
And given the time lag between Earth and Mars when they’re closest – 6 to 10 minutes, relying on whether or not the mission has entered the ambiance – the touchdown course of is an actual nail-biter. As Boykins put it:
“From the time we hit the higher ambiance of Mars ’til the automobile is bouncing alongside the floor, takes six minutes. However one-way gentle time from Mars – i.e. if a sign was despatched from Mars and despatched again to Earth – that sign would take ten minutes. So after we hit the higher ambiance, the rover despatched a sign again to Earth. Six minutes later, that sign was not at Earth, however the rover was bouncing alongside the floor of Mars. 4 minutes after that, we received a sign that it hit the higher ambiance. There’s nothing we are able to do as human beings to repair or save that automobile on its method in direction of the floor of Mars. If it doesn’t make it, it’s only a dangerous day.”
Right here lies one other concern that Boykins’ addressed, which is the fabled “Mars Curse“, which refers back to the 40% success price house businesses have had when making an attempt to land on Mars. However as he demonstrated utilizing a graphic that confirmed the totally different touchdown zones for NASA missions over time, the vary has narrowed significantly, owing to advances in know-how – notably when it comes to communication, navigation, and steerage methods.
Highlights from each missions adopted, which included how the Spirit and Alternative rovers vastly exceeded their mission parameters (function for 90 days and journey 600 meters). For its half, Alternative remained in operation for nearly 15 years and traveled a complete of 45.16 km (28.06 mi) – setting a brand new report for off-world distance travelled.
Whereas the rover’s mission was formally led to February, Boykins indicated that they could try and make contact with it once more sooner or later. One other spotlight was the mysterious rock that Alternative present in its touchdown space in 2005, which turned out to be the stays of an iron meteorite. This was the primary meteorite of any kind to ever be recognized on one other planet, but it surely was not the final.
For Curiosity, the highlights included the small ball-shaped metallic meteorite it got here throughout and studied with its laser, the various strains of proof that the Gale Crater (the place it landed in 2012) as soon as held a standing physique
In a practice going again to the Pathfinder mission (1997), this was achieved with an essay contest, the place college students from all around the US submitted concepts primarily based on what house exploration means to them. Again in September, NASA introduced that it was in search of companions for one more such contest, the place Ok-12 college students could have the prospect to call the Mars 2020 rover.
What adopted was some Q&A, the place the viewers received to ask questions on what it’s wish to work at NASA and what lies forward for Mars exploration. One factor that Boykins was clear on was that humanity mustn’t look to Mars as a “backup location”, which places him within the camp reverse folks like Elon Musk and Stephen Hawkins.
The excessive level of the night – for me, anyway – was the casual Q&A session that befell after the discuss was over. Boykins not solely let folks deal with the rover wheels he introduced with him from JPL – the identical form that have been used on the Sojourner and Alternative rovers (proven beneath) – he additionally let folks get some footage with him. I used to be one such particular person, as you’ll be able to see from the picture at prime.
For his accomplishments, Boykins was awarded the NASA Distinctive Service Medal, the very best honor that may be bestowed upon a civilian. Wanting forward, he can even play a significant function in creating the Europa Clipper mission, which shall be exploring Jupiter’s satellite tv for pc for indicators of potential life beneath the floor.
As a part of Nat Geo Stay’s “Exploring Mars”, Boykins shall be presenting to audiences throughout North America till January of 2020. To see the place occasions shall be happening (or to e book an occasion) take a look at the tour dates right here. And make sure you take a look at a few of Nationwide Geographic’s characteristic movies, the place Boykins’ discusses Mars exploration, the significance of planetary safety, and the 22 years he has spent working with NASA JPL.
