Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA operations engineer Daniel Velasquez, left, is reviewing the Mobile Vertipad Sensor Package system as part of the Air Mobility Pathways test project at NASA’s Armstrong Flight Research Center in Edwards, California, on Oct. 17, 2023.NASA/Steve Freeman Lee esta historia en Español aquí.
Born and raised in Peru, Daniel Velasquez moved to the United States when was 10 years old. While that decision was a big transition for his family, it also created many opportunities for him. Now Velasquez is an operations engineer for NASA’s Air Mobility Pathfinders project at NASA’s Armstrong Flight Research Center in Edwards, California.
Velasquez develops flight test plans for electric vertical take-off and landing (eVTOL) aircraft, specifically testing how they perform during various phases of flight, such as taxi, takeoff, cruise, approach, and landing. He was drawn to NASA Armstrong because of the legacy in advancing flight research and the connection to the Space Shuttle program.
“Being part of a center with such a rich history in supporting space missions and cutting-edge aeronautics was a major motivation for me,” Velasquez said. “One of the biggest highlights of my career has been the opportunity to meet (virtually) and collaborate with an astronaut on a possible future NASA project.”
Daniel Velasquez stands next to the main entrance sign at NASA’s Armstrong Flight Research Center in Edwards, California, in 2022.Daniel Velasquez Velasquez is incredibly proud of his Latino background because of its rich culture, strong sense of community and connection to his parents. “My parents are my biggest inspiration. They sacrificed so much to ensure my siblings and I could succeed, leaving behind the comfort of their home and family in Peru to give us better opportunities,” Velasquez said. “Their hard work and dedication motivate me every day. Everything I do is to honor their sacrifices and show them that their efforts weren’t wasted. I owe all my success to them.”
Velasquez began his career at NASA in 2021 as an intern through the Pathways Internship Program while he was studying aerospace engineering at Rutgers University in New Brunswick, New Jersey. Through that program, he learned about eVTOL modeling software called NASA Design and Analysis of Rotorcraft to create a help guide for other NASA engineers to reference when they worked with the software.
At the same time, he is also a staff sergeant in the U.S Army Reserves and responsible for overseeing the training and development of junior soldiers during monthly assemblies. He plans, creates, and presents classes for soldiers to stay up-to-date and refine their skills while supervising practical exercises, after action reviews, and gathering lessons learned during trainings.
Daniel Velasquez graduated in 2023 from Rutgers University in New Jersey while he was an intern at NASA. Behind him is the New York City skyline.Daniel Velasquez “This job is different than what I do day-to-day at NASA, but it has helped me become a more outspoken individual,” he said. “Being able to converse with a variety of people and be able to do it well is a skill that I acquired and refined while serving my country.”
Velasquez said he never imagined working for NASA as it was something he had only seen in movies and on television, but he is so proud to be working for the agency after all the hard work and sacrifices he made that lead him to this point. “I am incredibly proud to work every day with some of the most motivated and dedicated individuals in the industry.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)

Titan’s diameter is 50% larger than Earth’s moon.Credit: NASA NASA’s ambitious Cassini mission to Saturn in the late 1990s was one of the agency’s greatest accomplishments, providing unprecedented revelations about the esoteric outer planet and its moons. The complex undertaking was also a tremendous, yet bittersweet, achievement for the Lewis Research Center (today, NASA’s Glenn Research Center in Cleveland), which oversaw the rockets that propelled Cassini to Saturn. Cassini brought a close to over 35 years of Lewis’ management of NASA’s launch vehicles.
Cassini Mission: 5 Things to Know About NASA Lewis’ Last Launch
1. NASA Lewis Launched the Largest and Most Complex Deep-Space Mission to Date
In the early 1980s, NASA began planning the first-ever in-depth study of the planet Saturn. The mission would use the Cassini orbiter designed by NASA’s Jet Propulsion Laboratory in Southern California and the European Space Agency’s Huygens lander. It was one of the heaviest and most complex interplanetary spacecraft ever assembled. Cassini’s plutonium power system and intricate flight path further complicated the mission.
NASA Lewis was responsible for managing the launches of government missions involving the Centaur upper stage and the Atlas and Titan boosters. Cassini’s 6-ton payload forced Lewis to use the U.S. Air Force’s three-stage Titan IV, the most powerful vehicle available, and pair it with the most advanced version of the Centaur, referred to as G-prime.

One of NASA Lewis’ primary launch responsibilities was integrating the payload and upper stages with the booster. This involved balancing weight requirements, providing adequate insulation for Centaur’s cryogenic propellants, determining correct firing times for the stages, and ensuring that that the large shroud, which encapsulated both the upper stage and payload, jettisoned cleanly after launch.
By the time of Cassini, the center had been testing shrouds (including the Titan III fairing) in simulated space conditions for over 25 years. NASA’s Space Power Facility possesses the world’s largest vacuum chamber and was large enough to accommodate the Titan IV’s 86-foot-tall, 16-foot-diameter fairing. In the fall of 1990, the shroud was installed in the chamber, loaded with weights that simulated the payload, and subjected to atmospheric pressures found at an altitude of 72 miles.
The system was successfully separated in less than half a second. Using simulated Cassini and Centaur vehicles, NASA engineers also redesigned a thicker thermal blanket that would protect Cassini’s power system from acoustic vibrations during liftoff.

In late August 1997, a group of NASA Lewis engineers traveled to NASA’s Kennedy Space Center in Florida to make final preparations for the Cassini launch, working with Air Force range safety personnel at Patrick Air Force Base to ensure a safe launch under all circumstances.
After an aborted launch two days earlier, the vehicle was readied for another attempt in the evening of October 14. Lewis personnel took stations in the Launch Vehicle Data Center inside Hangar AE to monitor the launch vehicle’s temperature, pressure, speed, trajectory, and vibration during the launch. The weather was mild, and the countdown proceeded into the morning hours of October 15 without any major issues.
At 4:43 a.m. EDT, Titan’s first stage and the two massive solid rocket motors roared to life, and the vehicle rose into the dark skies over Florida. The Lewis launch team monitored the flight as the vehicle exited Earth’s atmosphere, Titan burned through its stages, and Centaur sent Cassini out of Earth orbit and on its 2-billion-mile journey to Saturn. After a successful spacecraft separation, Lewis’ responsibilities were complete. The launch had gone exceedingly well.

Cassini-Huygens was NASA Lewis’ 119th and final launch, and it brought to a close the center’s decades of launch operations. The center had been responsible for NASA’s upper-stage vehicles since the fall of 1962. The primary stages were the Agena, which had 28 successful launches, and Centaur, which has an even more impressive track record and remains in service today.
While Lewis continued to handle vehicle integration and other technical issues for launches of NASA payloads, in the 1980s, NASA began transferring launch responsibilities to commercial entities. In the mid-1990s, NASA underwent a major realignment that consolidated all launch vehicle responsibilities at NASA Kennedy.
So it was with mixed emotions that around 20 Lewis employees and retirees gathered at the Cleveland center in the early morning hours of Oct. 15, 1997, to watch the Cassini launch. The group held its cheers for 40 minutes after liftoff until Lewis’ responsibilities concluded for the last time with the safe separation of Cassini from Centaur. “In many ways, this is the end of an era, across the agency and, in particular, here at Lewis,” noted one engineer from the Launch Vehicle and Transportation Office.

Cassini’s seven-year voyage to Saturn included flybys of Venus (twice), Earth, and Jupiter so that the planets’ gravitational forces could accelerate the spacecraft. Cassini entered Saturn’s orbit in June 2004 and began relaying data and nearly half a million images back to Earth. Huygens separated from the spacecraft and descended to the surface of the Saturn’s largest moon, Titan, in January 2005. It was the first time a vehicle ever landed on a celestial body in the outer solar system.
Cassini went on to make plunges into the planet’s upper atmosphere and through Saturn’s rings. Scientific information on the mysterious planet, its moons, and rings led to the publication of nearly 4,000 technical papers. After over 13 years and nearly 300 orbits, on Sept. 15, 2017, NASA intentionally sent Cassini plummeting into the atmosphere where it burned up, ending its remarkable mission.
NASA engineers used their experiences from the Cassini mission to help design the Europa Clipper, which is intended to perform flybys of Jupiter’s moon Europa. Europa Clipper launched on Oct. 14.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Felipe Valdez, a NASA engineer at Armstrong Flight Research Center’s Dale Reed Subscale Flight Research Laboratory, stands next to a subscale model of the Hybrid Quadrotor (HQ-90) aircraft. NASA / Charles Genaro Vavuris Felipe Valdez is someone who took advantage of every possible opportunity at NASA, working his way from undergraduate intern to his current job as a flight controls engineer.
Born in the United States but raised in Mexico, Valdez faced significant challenges growing up.
“My mom worked long hours, my dad battled addiction, and eventually, school became unaffordable,” Valdez said.
Determined to continue his education, Valdez made the difficult choice to leave his family and return to the U.S. But as a teenager, learning English and adapting to a new environment was a culture shock for him. Despite these changes, his curiosity for subjects such as math and science never wavered.
“As a kid, I’d always been good with numbers and fascinated by how things worked. Engineering combined both,” Valdez said. “This sparked my interest.”
While he pursued an undergraduate degree in mechanical engineering from California State University, Sacramento, guidance from his professor, Jose Granda, proved to be pivotal.
“He encouraged me to apply for a NASA internship,” Valdez said. “He’d actually been a Spanish-language spokesperson for a [space] shuttle mission, so hearing about someone with my background succeed gave me the confidence I needed to take that step.”
Valdez’s hard work paid off – he was selected as a NASA Office of STEM Engagement intern at the agency’s Johnson Space Center in Houston. There, he worked on software development for vehicle dynamics, actuators, and controller models for a space capsule in computer simulations.
“I couldn’t believe it,” Valdez said. “Getting that opportunity changed everything.”
This internship opened the door to a second with NASA this time at the agency’s Armstrong Flight Research Center in California. He had the chance to work on flight computer development for the Preliminary Research Aerodynamic Design to Lower Drag, an experimental flying wing design.
After these experiences, he was later accepted as an intern for NASA’s Pathways Program, a work-study program that offers the possibly of full-time employment at NASA after graduation.
“That was the start of my career at NASA, where my passion for aeronautics really took off,” he said.
Valdez was the first in his family to pursue higher education, earning his bachelor’s degree from Sacramento State and his master’s in mechanical and aerospace engineering from the University of California, Davis.
Today, he works as a NASA flight controls engineer under the Dynamics and Controls branch at Armstrong. Most of his experience has focused on flight simulation development and flight control design, particularly for distributed electric propulsion aircraft.
“It’s rewarding to be part of a group that’s focused on making aviation faster, quieter, and more sustainable,” Valdez said. “As a controls engineer, working on advanced aircraft concepts like distributed electric propulsion allows me design algorithms to directly control multiple motors, enhancing safety, controllability, and stability, while enabling cleaner, and quieter operations that push the boundaries of sustainable aviation.”
Throughout his career, Valdez has remained proud of his heritage. “I feel a strong sense of pride knowing that inclusion is one of our core values, opportunities are within reach for anyone at NASA.”
