NASA Tests New Technologies in Reduced-g Flights: “NASA’s Flight Opportunities program supported testing various technologies in a series of parabolic flights earlier this year.” On the most recent flight, researchers tested equipment that uses ultrasonic tool for digging in the lunar or martian regolith. The sonic vibrations reduce cohesion between tool and regolith, making the tool more efficient, permitting a smaller size and power requirement to perform required digging/construction tasks. A follow-up experiment is planned for a sub-orbital flight in the future, where the test would be conducted in low-g and without atmosphere.
A second experiment was on the most recent flight. It involved an electrohydrodynamic ink jet printer being developed for use on the ISS and future microgravity locales for making electronics and semi-conductor devices.

NASA Selects Participating Scientists to Join ESA’s Hera Mission: Remember the Double Asteroid Redirection Test (DART)? The smaller asteroid in a two-asteroid system was struck at very high speed by part of DART while the other part watched. It was a test to determine if hitting an asteroid hard could alter its movements significantly, part of NASA’s Planetary Defense Program. The asteroid struck, Didymos, not only had its orbit around Dimorphos altered, it also had its shape altered by the impact. Didymos is a rock-pile asteroid, not a solid body, and the material rearranged itself rather than form a typical crater.
ESA’s Hera mission is designed as a part two to DART. It will visit Dimorphos/Didymos again to make detailed observations of the “new” version of Didymos, and it’s scheduled for launch in October. For more info and Hera and the participating scientists and instruments, see: https://www.jpl.nasa.gov/news/nasa-selects-participating-scientists-to-join-esas-hera-mission.
NASA is planning a DYNAMIC mission (DYnamical Neutral AtMosphere-Ionosphere Coupling) in response to the 2013 Decadal Survey for Solar and Space Physics, NASA’s guide for future missions to study the Sun and its effects on the interplanetary environment and Earth. The “DYNAMIC mission is designed to study how changes in Earth's lower atmosphere influence our planet's upper atmosphere, where space weather like auroras and satellite disruptions are manifested. This knowledge will benefit humanity by helping us understand how space weather can interfere with crucial technology like navigation systems and satellites.”
NASA put out a Request for Proposals for the mission, and selected three of the responders for development funding for their mission concepts. The PI’s of two of the proposal teams are from the University of Colorado; the third PI is based at VPI. For more information on DYNAMIC and the proposals, see: https://www.jpl.nasa.gov/news/nasa-funds-study-of-proposals-to-investigate-space-weather-systems.

JPL’s Theodore von Kármán Lecture Series is an outstanding educational resource. One recent lecture was “Shake & Bake: How Spacecraft Are Tested to Handle the Harsh Environment of Space,” mentioned below. JPL has posted 115 past von Kármán lectures, covering a wide range of topics; for more on the lecture series, see: https://www.jpl.nasa.gov/jpl-and-the-community/lecture-series.
Preparing for Space: Space is hostile to people and equipment alike. Have you ever wondered about how NASA makes sure its spacecraft can survive and operate successful in interplanetary Space and on other planets? NASA recently streamed one of the JPL von Kármán Lecture Series entitled “Shake & Bake: How Spacecraft are Tested to Handle the Harsh Environment of Space.” The featured lecturers are Brad Kinter, a Group Supervisor in JPL’s Environmental Thermal Testing unit at JPL and Pete Landry, Systems Integration and Test Engineer at JPL. The lecture is now available on YouTube at: https://www.jpl.nasa.gov/jpl-and-the-community/lecture-series/the-von-karman-lecture-series-2024/may-2024-shake-bake-how-spacecraft-are-tested-to-handle-the-harsh-environment-of-space.
Theodore von Kármán was an aerodynamics expert who came to the USA in 1930, fleeing rising tide of Nazism. He was a member of the National Academy of Science and one of the founders of the Jet Propulsion Laboratory. The lecture series named for him routinely offers a number of interesting Space-related lectures, “Shake and Bake,” being one of the most recent. For more information on von Kármán, see: https://www.nasonline.org/publications/biographical-memoirs/memoir-pdfs/von-karman-theodore.pdf.
No Surprise Here! NASA Earns “Best Place to Work in Government for the 12th Straight Year! The Partnership for Public Service has been compiling Federal employees’ viewpoints regarding Agency leadership, work/life balance, and other job factors since 2003, and I am NOT surprised that NASA has won AGAIN. For more on PPS and their evaluation, see here.
Swarming for Success: NASA is experimenting with the use of swarms of small satellites that work as an autonomous team. The first effort, called “Starling,” has been in LEO for ten months, successfully demonstrating the cube-sat team concept. Such “(a)n autonomous network of spacecraft could self-navigate, manage scientific experiments, and execute maneuvers to respond to environmental changes without the burden of significant communications delays between the swarm and Earth.“ For more on Starling, see: https://www.nasa.gov/mission/starling. The idea of using a number of spacecraft working autonomously in union, is not limited to LEO, it also is due for testing on the Moon:
CADRE of Mini-robots Moon-Bound:Cooperative Autonomous Distributed Robotic Exploration is technology demonstration project involving a number of small robots to be landed on the Moon, where they will explore the landing area collectively, without direct guidance from Earth. The robots will take images of the surface, map the area in which they are collectively operating, and utilize ground-penetrating radar to explore the lunar subsurface. “The goal is to show that a group of robotic spacecraft can work together to accomplish tasks and record data as a team without explicit commands from mission controllers on Earth. If the project succeeds, future missions could include teams of robots spreading out to take simultaneous, distributed scientific measurements, potentially in support of astronauts.” For more information, see: https://www.jpl.nasa.gov/news/nasas-network-of-small-moon-bound-rovers-is-ready-to-roll.
Did you know that NASA has an entire Scientific Visualization Studio at the Goddard Space Flight Center? The data they make relatable is really terrific, check it out at: https://svs.gsfc.nasa.gov.
NASA’s Six New Innovative Tech Concepts have been selected for additional development funding by the NASA Innovative Advanced Concepts program. NIAC is one of the reasons NASA can seem to do the impossible for the benefit of us all. The ideas sound like science fiction: a Space telescope that uses a fluid shaped by ionic liquids as its mirror; a pulsed plasma rocket that could significantly reduce Earth-Mars travel time; an orbital radio telescope comprising thousands of SmallSats; an advanced Radioisotope Thermal Generator; a lunar maglev railway system; and a solar sail with quantum dot sensors for exploration of the outer Solar System. What an exciting time to be alive!
Europa Clipper Spacecraft Message: NASA has placed plaques aboard various Spacecraft in the past, including those on both Pioneers and both Voyagers. The plaque for the upcoming Europa Clipper was rolled out last week. It’s made of tantalum (to help protect internal electronics from Jupiter’s intense radiation field) and carries messages, both written and audio, and the names of more than 2.8 million people. It also has an engraved portrait of the late Ronald Greeley of Arizona State University, who was a big advocate of a mission to Europa. He was also the dissertation advisor for Bob Pappalardo, the Europa Clipper’s Principal Investigator (and mine’s, too!). For more info about the Europa Clipper mission, see here; for more about the Plaque, see here. For more about Ron Greeley, see here and here. But wait, there’s …
More About Europa: Europa lies in the middle of a belt filled with charged particles, think the Van Allen Belts at Earth on steroids. Europa has an icy surface, and the intense rain of ions dissociate the water ice on the surface into hydrogen and oxygen. Almost all of the former and much of the latter are then lost to Space, but some of the oxygen might reach the ocean beneath the ice, affecting potential biological development there. For more information, see: https://www.jpl.nasa.gov/news/nasas-juno-mission-measures-oxygen-production-at-europa.
NASA’s New Website! “NASA has switched its primary World Wide Web addresses to a beta version of the new NASA.gov and science.nasa.gov websites, continuing the long-term development and consolidation of its public web presence.
