DTS TSR PRO onboard Artemis 1

We are proud to announce that a DTS TSR PRO data logger is traveling beyond the moon onboard Artemis 1, to help capture vital acceleration and vibration data that can help improve astronaut safety on the upcoming crewed mission, Artemis II.

Space, the final frontier… now, as we reach further into space, exploring that “final frontier” is no longer an if, but a when. With the recent launch of Artemis 1, part of NASA’s Artemis program developed to return us to the moon and beyond, we are that much closer to glimpsing more of what is ‘out there.’

Artemis 1, crewed by a manikin, is a mission of testing new technologies. The new technologies include the Space Launch Rocket (SLS) system, the most powerful rocket in the world. According to NASA1:

The crew is expected to experience 2.5 times the force of gravity during ascent and four times the force of gravity at two different points during the planned reentry profile. Engineers will compare Artemis I flight data with previous ground-based vibration tests with the same manikin, and human subjects, to correlate performance prior to Artemis II.

To help gather this data, the manikin’s seat is outfitted with sensors designed to record acceleration and vibration data during the mission. The DTS TSR PRO data logger, which is embedded in the seat back, is triggered to record when the hatch door closes. The vital acceleration data captured by the TSR PRO will help NASA better understand what forces astronauts may experience on Artemis II, the first scheduled crewed mission of the Orion spacecraft set for 2024.

“It’s critical for us to get data from the Artemis I manikin to ensure all of the newly designed systems, coupled with an energy dampening system that the seats are mounted on, integrate together and provide the protection crew members will need in preparation for our first crewed mission on Artemis II,” said Jason Hutt, NASA lead for Orion Crew Systems Integration.

The DTS TSR PRO is a compact rugged data logger that makes it easy to measure acceleration forces in extreme test environments such as rocket launches, space flight, and splashdowns. The data logger has a built-in data recorder and sensors and is self-powered for unattended monitoring of acceleration and vibration. When the hatch door of the capsule closes it triggers the TSR PRO to begin recording to capture that key data which can help contribute to astronaut safety on future missions. 

Congratulations NASA on this historical enterprise. We can’t wait to see what’s next!

UPDATE: NASA successfully launched the Artemis 1 moon mission on the first Space Launch System rocket at 1:47 am EST (0647 GMT) on November 16, 2022.

On July 20, 1969, we made that first giant step and landed on the moon. Now, Artemis 1, part of a series of missions – missions that will bring us back to the moon and the hope of establishing a human presence there, is about to take off. The launch date for this historic event is scheduled for August 29. (UPDATE – the first two launch attempts were scrubbed due to issues NASA could not troubleshoot within the launch windows. “We do not launch until we think it’s right,” NASA Administrator Bill Nelson said.)

Lift off will be at NASA’s Kenny Space Center and Artemis 1 will be the first to use the most powerful rocket in the world, known as the Space Launch System Rocket (SLS) which will propel the Orion spacecraft for the first minutes of the mission. Artemis 1 will travel beyond the moon, further than any spacecraft built for humans has gone before. The 42-day duration mission will function as a demonstration of Orion’s systems prior to sending up a manned mission. Expected splashdown date is currently set for Oct. 10, 2022, at a reentry speed of 24,500 miles per hour – hotter and faster than any reentry before.

For these new missions, innovative technologies have had to be designed and tested. As part of assisting with future crew safety, the DTS TSR PRO data logger was used to help quantify the acceleration profile of the crew seat backs on launch. The closing of the hatch door triggers the TSR PRO to record and capture vital data which helps contribute to the success of these missions.

This first Artemis mission will be “manned” by Commander Moonikin Campos, a suited mannikin strapped in the commander’s seat on Orion. “Some data collected from Artemis I will be used for Orion crew simulations and to verify crew safety by comparing flight vibration and acceleration against pre-flight predictions, then making model refinements as necessary,” said Dr. Mark Baldwin, Orion’s occupant protection specialist for lead contractor Lockheed Martin.1

DTS would like to wish NASA and all organizations that have contributed to these upcoming missions, good luck! We are proud that DTS data acquisition equipment has been chosen by NASA for more than 3 decades to support their aerospace testing.

Successful crash test meets major milestone for nuclear deterrence program Article Written By: Manette Newbold Fisher / Sandia Lab News Vol. 72, No. 20, October 9, 2020 A full-scale crash test involving a semitruck impacting the side of the first prototype of a new weapons transporter successfully took place at Sandia this summer. Using the Labs’ sled track, rockets propelled the semitractor-trailer at highway speeds into the prototype, an over-the-road Mobile Guardian Transporter conceptualized and built from scratch. Data from the event will be used for qualification of the transporter and to better understand cargo response in accident scenarios for years to come.
This test met a major milestone for NNSA as part of the Labs’ nuclear deterrence program, said Gary Laughlin, Sandia director over the program. Eventually, the new transporters will replace the current fleet of vehicles that safely and securely move nuclear assets within the United States.
“Completing this milestone is one example of Sandia’s dedication to the Office of Secure Transportation and the nuclear deterrence program,” Gary said. “Very creatively and with the help of many teams throughout Sandia, Los Alamos and Lawrence Livermore national laboratories, we figured out how to build a new trailer and complete a test that was flawlessly executed.” Biggest crash test in decades Crash tests at this scale using transporter vehicles have not taken place at the Labs for about 20 years, said Jim Redmond, senior manager over the program, adding that Sandia has never executed a test quite like this one at full scale. “About two decades ago, Sandia crashed a truck into an immovable barrier, but this is the first time we’ve done a test in this configuration, where we took a truck at full capacity and propelled it down the track and hit our test article sitting idly at the end of it,” Jim said. “In two decades, you can imagine how much technology has advanced in terms of our ability to measure responses of the trailer and its contents.” One purpose of the crash test, said manager Daniel Wilcox, was to ensure the new fleet of semitrailer transporters will be able to keep cargo safe in the event of an unexpected crash. Sandia’s primary mission is ensuring the U.S. nuclear arsenal is safe, secure and reliable. As part of that mission, and since the inception of nuclear deterrence, Sandia has played an important role in transportation, Jim said. “The transportation mission is a critical component of an effective nuclear deterrent,” he said. “It provides needed assurance to the American public and our allies of the safety and security of our stockpile. You’ve got to be able to ship nuclear assets safely and securely or you don’t have a deterrence program.” Starting ‘with a clean sheet of paper’ Sandia manager Barry Boughton was part of the team that worked on the previous fleet of transporters that have been in use since the 1990s. Following testing on additional prototypes in coming years, the current set of transporters will be replaced by the Mobile Guardian Transporter fleet, which is expected to be in service beyond 2050. Barry said the transporter systems begin with demanding requirements that change with each fleet as technology and the operating environment evolve. From there, the design team begins creating a brand-new system. “The Mobile Guardian Transporters are not an extension of the old trailers,” he said. “We started with a clean sheet of paper.” Nearly everything that makes up the transporters is custom designed and built, with a few exceptions. It was a multiyear design effort to get to the point where Sandia could work with an external partner to build the road-ready trailer. Initially, the prototype didn’t have any electronics or finishing touches. Following the 13-month trailer build, the team worked for an additional six months assembling electronics before they began testing the prototype in normal and abnormal environments. Normal environment tests included such activities as driving the transporter on the road while measuring shock and vibration response and exposing the vehicle to thermal cycling while measuring its response to various temperatures. From January to June, the team prepped the vehicle for the crash test by setting up data-acquisition instrumentation and configuring and installing representative cargo. Setting up the channels was one of the most challenging technical aspects of test setup, said Kylen Johns, prototype project lead. “We had a goal of gathering an unprecedented amount of data, realizing that it would be extremely difficult in such a harsh environment,” she said. “To reduce risk, we built in redundancy to the systems and included peer reviewers in every step of the preparation. We were crashing a semi into another semi, and protecting these super tiny, thin cables meant the difference between getting critical data or missing major objectives.” During the test, more than 400 channels of data and video, including high-speed video, were collected, Jim said. Every sensor served a purpose and provided specific data that the team analyzes to make sure the transporter meets all requirements. The team will only build three prototypes, so every scrap of data is meaningful to the project. Test day collaboration The complexity of the setup required the multiorganization crash test execution team and other collaborating groups to remain “laser-focused” for months, Daniel said, to ensure the crash date wasn’t delayed, the test objectives were met and data wasn’t compromised. The prototype was moved to the test site in June, where employees continued preparing for the crash in pandemic conditions, in the heat of the desert — running cables, fixing problems, soldering wires, setting up cameras, checking acquisitions systems and setting triggers. On test day, final preparation started several hours before dawn. Around midday, the test execution team, transporter team members and stakeholders stood at a safe distance from the sled track and watched the crash take place. There was a lot of buildup to that point, Jim said, with the years-long effort resulting in a transporter assembly test that was over in a matter of seconds. “I was glad to see the rockets fired; I was glad to see it was successful,” he said. “It was tense. The entire team, including partners from LANL and Lawrence Livermore, were excited and relieved. There’s a lot of pride among the team, as well as the government sponsors, that we are greatly increasing our understanding of accident environments.” Karen Rogers, senior manager for Sandia’s validation and qualification team, oversees the group that designed and conducted the rocket-sled test. Karen praised the seamless collaboration between teams, saying, “We worked in partnership, and at times side-by-side, to create all the elements that led to this successful test. It was gratifying to see the results of that hard work and the teamwork that made it happen.” Deadline met despite pandemic Before the COVID-19 pandemic started to impact many Sandia operations in early March, activities were on track for the summer test, Daniel said. Threat of the virus understandably complicated work across the program, but the team came together to keep things moving forward toward the test. “There was a feeling of, ‘What are the impacts of the pandemic on this test — and can we really do this?’” he said. “Even though the unexpected challenge of COVID-19 added significant complications to an already-complex test, the crash was executed on the precise day it was planned before the pandemic, with no delay.” Because completing the test on time was critical to NNSA, much of the team continued working on site when about 70% of Labs employees started telecommuting in mid-March. Sandia industrial health and Environment, Safety & Health professionals helped the team work effectively in close quarters by requiring masks, checking ventilation systems and advising on how to take turns inside the vehicle, Gary said. The team’s procedures set a standard for social distancing at the Labs. “Years of effort from the entire team and our partners, punctuated by the final push in a COVID-impacted world, resulted in a successful test,” Daniel said. “We are delighted by and grateful for the effort of so many that led to such spectacular results.”

New aPLI Advances Pedestrian Safety

New aPLI Advances Pedestrian Safety

New aPLI Advances Pedestrian Safety

Seal Beach, CA – According to the World Health Organization, more than 5,000 pedestrians are killed each week worldwide. The Governors Highway Safety Association reported that pedestrian fatalities in the USA have risen by 41% since 2008 – the highest in 30 years.
Starting in 2022, Euro NCAP announced that it will adopt the new advanced Pedestrian Legform Impactor (aPLI) in its testing. The aPLI weighs 24.9kg (55 lb), compared with the 13.2kg (29 lb) Flex PLI, and the mass distribution has been refined to be more biofidelic, top to bottom. The structural design has also been simplified to improve repeatability and reproducibility of results.
Like its Flex PLI predecessor, the aPLI features integrated data acquisition and sensors from DTS. The aPLI legform supports SLICE NANO, along with the 6DX PRO six degrees of freedom sensor package and the ARS PRO uniaxial angular rate sensor
Using the SLICE NANO stack extender, a special DTS mounting hardware solution designed for applications with limited height restrictions, the modular sensor layers can be split into two stacks, but still require only one BASE+. The standard aPLI configuration includes 18 sensor channels focused on three primary types of measurements: injury assessment, flight dynamics and vehicle impact
Embedding the data acquisition into the test article minimizes exposed cables throughout the leg and eliminates any trailing cables that could affect the launch.  DTS offers a complete turnkey solution engineered to maintain proper mass, center of gravity and moments to help advance pedestrian safety testing.
