Preparations for Next Moonwalk Simulations Underway (and Underwater)
A NASA logo-themed cake serves as a centerpiece for the event. Credit: NASA/Jef Janis Over 4,300 visitors joined in the fun to commemorate the 65th birthday of NASA’s iconic logo on July 15 at Great Lakes Science Center (GLSC) in downtown Cleveland.
The birthday celebration featured a cake-cutting ceremony and special NASA activities throughout the day, including presentations from NASA’s Glenn Research Center photographers and videographers, a talk from a NASA librarian on the history of the logo, photo opportunities with Glenn’s Eva the Astronaut mascot, a coloring contest, a performance by the NASA Glenn Band, live science shows, and more.

The iconic symbol, known affectionately as “the meatball,” was developed at NASA’s Lewis Research Center in Cleveland (now called NASA Glenn). Employee James Modarelli, who started his career at the center as an artist and technical illustrator, was its chief designer.

Preparations for Next Moonwalk Simulations Underway (and Underwater)

An orbiting laboratory for deep space science and a staging ground for lunar exploration, Gateway will help NASA and its international partners establish a sustained human presence on and around the Moon in preparation for the next giant leap – human exploration of Mars.
High-gain antennas are an important component of Gateway’s communication and tracking system that connects operations across the vast distances of the lunar South Pole region, to Gateway in orbit around the Moon, to Earth, and back again.
NASA is conducting rigorous testing on the electric field levels radiated by the antennas to ensure safe and efficient communication and to avoid any interference with Gateway’s crew and equipment. By validating simulation models to accurately predict electric field levels, NASA can establish precise safety zones around the K/Ka-band parabolic reflector antennas to protect astronauts and hardware without sacrificing high-rate communications.
During the meticulous testing process, engineers use electric field and waveguide probes, which measure the strength and quality of electromagnetic signals, to scan the near fields of a representative high-gain antenna. Robotic arms and optical tracking systems provide the precise measurements needed for model validation. The testing is being conducted in an anechoic chamber, a specialized room that provides a controlled environment for measurements of electromagnetic waves.
“We are sharpening our pencil in conducting model validation measurements – ensuring high accuracy in the analysis of electric fields radiated by the high-gain antennas on Gateway,” said Timothy Kennedy, one of the NASA engineers overseeing the tests. “This enables reduced margins on antenna masking needed to protect equipment and crew, while maximizing communication coverage.”
Findings are expected to enhance NASA’s understanding of the electric field levels emitted by Gateway’s antennas and inform critical decisions for operating them safely during Artemis missions, ensuring that Gateway is a safe home for astronauts around the Moon.

NASA eClips Engages Families at 2024 STEM Community Day
On Saturday, June 1, 2024, thousands of community members attended the Science, Technology, Engineering, & Mathematics (STEM) Community Day hosted by Christopher Newport University in partnership with Newport News Public Schools in Virginia. The event showcased many different facets of STEM fields and careers and offered hands-on experiences by nearly 100 exhibitors. Educators from the National Institute of Aerospace’s Center for Integrated STEM Education (NIA-CISE) engaged learners of all ages at this annual event with a 13-foot tree. Participants learned how to measure tree height using a clinometer and why NASA collects this data with the help of volunteers, also knowns as “citizen scientists” (e.g. one reason is to calculate how much carbon trees and forests take in or release into the atmosphere). Each family was able to take home a kit to make their own clinometers. Another activity offered by the NIA-CISE team involved learning about Earth’s energy balance (e.g. participants selected cards of activities that either reflect energy back to space or are absorbed by Earth and had to decide whether those activities belonged to the “in” or “out” side of Earth’s energy balance).
NASA eClips is supported by NASA under cooperative agreement award number NNX16AB91A and is part of NASA’s Science Activation Portfolio. Learn more about how Science Activation connects NASA science experts, real content, and experiences with community leaders to do science in ways that activate minds and promote deeper understanding of our world and beyond: https://science.nasa.gov/learn

A collaboration between the MSFC Lightning Team, NOAA NESDIS, and the NASA ARSET (Applied Remote Sensing Training) team completed on 4/2/24 with the final installment of a three-part series focused on Lightning Observations and Applications. On 3/26/24, Part 1 was presented to an audience of people from around the globe focused on the background and history of lightning measurements. This presentation was given by Steven Goodman of Thunderbolt Technologies. Part 2 was titled” Overview of Current Lightning Data Products from Remote Sensing” and was given by MSFC Lightning lead Timothy Lang (ST11). This presentation focused a lot on NASA lightning missions, field campaigns, and data access and was given on 3/28/24. The final installment of the ARSET lightning series was given on 4/2/24 by Scott Rudlosky of NOAA NESDIS and Christopher Schultz (ST11) of MSFC. This third part focused specifically on the Geostationary Lightning Mapper and applications of the data for science, identify lightning hazards, and safety. The average total attendance was around 225 people per session. Schultz took a lead role in working with the ARSET team to identify the speakers, topics, and review materials for presentation. Each of the 6 sessions (2 per day per topic, 1.5 hours each session) were followed up with 10-15 questions from the audience. The ARSET team indicates that there is potential for additional lightning-based trainings going forward given the response to this first series.
