NASA NASA astronaut Raja Chari and Dr. V. Narayanan, chairman of ISRO (Indian Space Research Organisation), interact outside the Orion spacecraft mockup at NASA’s Johnson Space Center in Houston. Narayanan and Indian officials visited NASA Johnson and NASA’s Kennedy Space Center in Florida, ahead of the Axiom Mission 4 launch to the International Space Station.
As part of a collaboration between NASA and ISRO, Axiom Mission 4 delivers on a commitment highlighted by President Trump and Indian Prime Minister Narendra Modi to send the first ISRO astronaut to the station. The space agencies are participating in five joint science investigations and two in-orbit science, technology, engineering, and mathematics demonstrations. NASA and ISRO have a long-standing relationship built on a shared vision to advance scientific knowledge and expand space collaboration.

NASA has awarded a task order to Florida Power and Light of Juno Beach, Florida, to provide electric distribution utility service at the agency’s Kennedy Space Center in Florida.
This is a fixed-price task order with an estimated value of $70 million over five years. The contract consists of a two-year base period beginning July 1, 2025, followed by a two-year and a one-year option period.
Under the contract, the awardee will provide all management, labor, transportation, facilities, materials, and equipment to provide electric distribution utility service up to and including all meters across the spaceport.

In Memoriam: Dr. Stanley Sander
Dr. Stanley Sander dedicated more than five decades to atmospheric science at the Jet Propulsion Laboratory, beginning his JPL career as a graduate research assistant in 1971. A leading figure in atmospheric chemistry, Stan made foundational contributions to our understanding of stratospheric ozone depletion, tropospheric air pollution, and climate science related to greenhouse gases.
His pioneering work in laboratory measurements—particularly of reaction rate constants, spectroscopy, and photochemistry—was designed to forge consensus among often disparate measurements. His steadfast application of the scientific method was essential for furthering scientific research, as well as for providing sound advice for use in air quality management and environmental policies. His expertise extended beyond Earth’s atmosphere, with studies of methane chemistry on Mars, halogens on Venus, and hydrocarbons in Titan’s atmosphere.
Stan’s scientific output was vast. He authored over 180 peer-reviewed publications, beginning with his 1976 paper on sulfur dioxide oxidation. His work spans major aspects of atmospheric chemistry—from chlorine, bromine, and nitrogen oxides to sulfur compounds and peroxides. The rate constants, cross-sections, and photochemical data produced in his lab form the cornerstone of atmospheric modeling crucial to the scientific foundation of the Montreal Protocol on Substances that Deplete the Ozone Layer. He played a central role in the widely used JPL Chemical Kinetics and Photochemical Data for Use in Atmospheric Studies reports, which have collectively garnered over 10,000 citations. His spectroscopic research, which included development of novel spectrometers and polarimeters, resulted in insightful data from sites at JPL, the Table Mountain Facility as well as the California Laboratory for Remote sensing (CLARS). These activities have contributed significantly to the calibration and validation of satellite missions like TES, OCO, OMI, and SAGE, helped advance remote sensing technologies, and informed local air quality metrics.
Stan was not only a brilliant scientist but a deeply respected mentor and leader. He guided 40 postdocs at JPL, 14 graduate students at Caltech, and 14 undergraduate researchers. At JPL, he held key leadership roles including Supervisor of the Laboratory Studies and Modeling Group, Chief Engineer and Acting Chief Technologist in the Science Division, and Senior Research Scientist. Those of us lucky enough to be fostered by Stan in this capacity will always remember his kindness first approach and steadfast resolve in the face of challenges.
Stan’s contributions were recognized with numerous honors, including two NASA Exceptional Achievement Medals, a NASA Exceptional Service Medal, and elected as a fellow for both the American Geophysical Union (2021) and the American Association for the Advancement of Science (2024). Although the announcement of his AAAS Fellowship came posthumously, he was informed of this honor before his passing.
Stan was a rare combination of scientific brilliance, humility, and kindness. He was not only a leader in his field, but also a generous collaborator and cherished mentor. His loss is profoundly felt by the scientific community and by all who had the privilege of working with him. His legacy, however, will endure in those he mentored and the substantial contributions he made to scientific knowledge.

NASA’s RASSOR (Regolith Advanced Surface Systems Operations Robot) undergoes testing to extract simulated regolith, or the loose, fragmental material on the Moon’s surface, inside of the Granular Mechanics and Regolith Operations Lab at the agency’s Kennedy Space Center in Florida on May 27. Ben Burdess, mechanical engineer at NASA Kennedy, observes RASSOR’s counterrotating drums digging up the lunar dust and creating a three-foot berm.
The opposing motion of the drums helps RASSOR grip the surface in low-gravity environments like the Moon or Mars. With this unique capability, RASSOR can traverse the rough surface to dig, load, haul, and dump regolith that could later be broken down into hydrogen, oxygen, or water, resources critical for sustaining human presence.
The primary objective was testing the bucket drums that will be used on NASA’s IPEx (In-Situ Resource Utilization Pilot Excavator). The RASSOR robot represents an earlier generation technology that informed the development of IPEx, serving as a precursor and foundational platform for the advanced excavation systems and autonomous capabilities now being demonstrated by this Moon-mining robot.

Students from Eau Gallie High School in Melbourne, Florida, visited the Prototype Development Laboratory at NASA’s Kennedy Space Center in Florida on Monday, April 28, 2025. The science, technology, engineering, and mathematics (STEM) participants are interested in technical trades and had the chance to hear from technicians at the Prototype Development Laboratory who design, fabricate, and evaluate protypes, test articles, and test support equipment.
NASA Kennedy’s Office of STEM Engagement provides opportunities to attract, engage, and enable students seeking careers in science, technology, engineering, and mathematics.
“My technical training in high school plays a huge role in the work I do every day in the Prototype Laboratory,” said Spencer Wells, mechanical engineering technician at Prototype Development Laboratory. “If it weren’t for that training, I’m convinced I wouldn’t be here at NASA.”
Some of the participants also have worked on a project to design and build a wheel for a lunar excavator demonstration mission as part of the NASA HUNCH program, an instructional partnership between NASA and educational institutions.
