Final Venus Flyby for NASA’s Parker Solar Probe Queues Closest Sun Pass
On Wednesday, Nov. 6, 2024, NASA’s Parker Solar Probe will complete its final Venus gravity assist maneuver, passing within 233 miles (376 km) of Venus’ surface. The flyby will adjust Parker’s trajectory into its final orbital configuration, bringing the spacecraft to within an unprecedented 3.86 million miles of the solar surface on Dec. 24, 2024. It will be the closest any human made object has been to the Sun.
Parker’s Venus flybys have become boons for new Venus science thanks to a chance discovery from its Wide-Field Imager for Parker Solar Probe, or WISPR. The instrument peers out from Parker and away from the Sun to see fine details in the solar wind. But on July 11, 2020, during Parker’s third Venus flyby, scientists turned WISPR toward Venus in hopes of tracking changes in the planet’s thick cloud cover. The images revealed a surprise: A portion of WISPR’s data, which captures visible and near infrared light, seemed to see all the way through the clouds to the Venusian surface below.
“The WISPR cameras can see through the clouds to the surface of Venus, which glows in the near-infrared because it’s so hot,” said Noam Izenberg, a space scientist at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland.
Venus, sizzling at approximately 869 degrees Fahrenheit (about 465 C), was radiating through the clouds.
The WISPR images from the 2020 flyby, as well as the next flyby in 2021, revealed Venus’ surface in a new light. But they also raised puzzling questions, and scientists have devised the Nov. 6 flyby to help answer them.
Left: A series of WISPR images of the nightside of Venus from Parker Solar Probe’s fourth flyby showing near infrared emissions from the surface. In these images, lighter shades represent warmer temperatures and darker shades represent cooler. Right: A combined mosaic of radar images of Venus’ surface from NASA’s Magellan mission, where the brightness indicates radar properties from smooth (dark) to rough (light), and the colors indicate elevation from low (blue) to high (red). The Venus images correspond well with data from the Magellan spacecraft, showing dark and light patterns that line up with surface regions Magellan captured when it mapped Venus’ surface using radar from 1990 to 1994. Yet some parts of the WISPR images appear brighter than expected, hinting at extra information captured by WISPR’s data. Is WISPR picking up on chemical differences on the surface, where the ground is made of different material? Perhaps it’s seeing variations in age, where more recent lava flows added a fresh coat to the Venusian surface.
“Because it flies over a number of similar and different landforms than the previous Venus flybys, the Nov. 6 flyby will give us more context to evaluate whether WISPR can help us distinguish physical or even chemical properties of Venus’ surface,” Izenberg said.
After the Nov. 6 flyby, Parker will be on course to swoop within 3.8 million miles of the solar surface, the final objective of the historic mission first conceived over 65 years ago. No human-made object has ever passed this close to a star, so Parker’s data will be charting as-yet uncharted territory. In this hyper-close regime, Parker will cut through plumes of plasma still connected to the Sun. It is close enough to pass inside a solar eruption, like a surfer diving under a crashing ocean wave.
“This is a major engineering accomplishment,” said Adam Szabo, project scientist for Parker Solar Probe at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
The closest approach to the Sun, or perihelion, will occur on Dec. 24, 2024, during which mission control will be out of contact with the spacecraft. Parker will send a beacon tone on Dec. 27, 2024, to confirm its success and the spacecraft’s health. Parker will remain in this orbit for the remainder of its mission, completing two more perihelia at the same distance.
Parker Solar Probe is part of NASA’s Living with a Star program to explore aspects of the Sun-Earth system that directly affect life and society. The Living with a Star program is managed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland, for NASA’s Science Mission Directorate in Washington. The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, manages the Parker Solar Probe mission for NASA and designed, built, and operates the spacecraft.

Science Activation’s PLACES Team Facilitates Third Professional Learning Institute
The NASA Science Activation program’s Place-Based Learning to Advance Connections, Education, and Stewardship (PLACES) project supports middle and high school educators to engage students in data-rich Earth science learning through the integration of NASA data sets, images, classroom lessons, and other assets. This project draws on a place-based approach as a means to increase “data fluency” — the ability and confidence to make sense of and use data. This means knowing when, how, and why to use data for a specific purpose, such as solving problems and communicating ideas grounded in evidence.
As part of this effort, PLACES facilitated its third Professional Learning (PL) Summer Institute (SI) for 22 educators at the Gulf of Maine Research Institute (GMRI) in Portland, Maine the week of August 12th, 2024. This is the third PL Summer Institute the PLACES team has facilitated, each focusing on engaging educators in place-based, data-rich teaching and learning with NASA data and resources.
The GMRI PL development and facilitation was a collaborative co-design effort between two NASA Science Activation projects (PLACES led by WestEd and the Learning Ecosystems Northeast project led by GMRI) and colleagues from the Concord Consortium and NASA Langley Research Center. During this PL, teachers took part in community science projects developed by GMRI to incorporate youth in ongoing research projects, including a mix of field- and classroom-based experiences that explored the phenomena of Hemlock Woolly Adelgid (HWA) and the changes to intertidal crab populations – two invasive species that are proliferating as a result of climate change. During two field-based experiences, teachers gathered primary data using protocols from GMRI’s Ecosystem Investigation Network and the NASA-sponsored program, GLOBE (Global Learning and Observations to Benefit the Environment). Teachers then explored these primary data using Concord Consortium’s Common Online Data Analysis Platform (CODAP) to better understand the geographic and temporal spread of these species. To connect their local experiences to global happenings, teachers then explored secondary data sets, including those sourced from the My NASA Data (MND – also supported by NASA Science Activation as part of the GLOBE Mission Earth project) Earth System Explorer (e.g., Normalized Difference Vegetation Index, salinity, sea surface temperature). The facilitation team also used the MND Data Literacy Cubes to encourage teachers to consider a multitude of diverse questions about place, data, and the phenomena. The GLOBE protocols supplemented existing GMRI data collection protocols, presenting new opportunities for teachers already experienced with HWA and Green Crabs. The MND data and Data Literacy Cubes moved teachers from questions they generated as part of their primary data collection towards new knowledge.
Daily feedback from teachers highlighted their appreciation for the responsiveness of the facilitation team, as well as a growing curiosity and desire for using NASA resources such as protocols from GLOBE and data from MND’s Earth System Explorer. This is exciting to see as the teachers transition from the Summer Institute into a virtual Community of Practice during the school year. The Community of Practice engages them in peer-to-peer collaboration and dialogue as they develop, test, and give feedback on their own place-based, data-rich experiences using NASA data and resources. So far, teachers are planning to tackle a variety of topics ranging from ocean chemistry to human connections to the environment. Teachers indicated their interest in “making place-based experiences meaningful to our unique populations of students and having cultural representation in the classroom,” and focusing on “cross-school collaboration.” Preliminary evaluation data indicated that 76% of teachers thought their experiences with NASA resources during the SI helped them identify ways to bring data into their classroom. 85% of teachers indicated they feel a greater connection to NASA and knowledge of NASA resources for enhancing student understanding and engagement in science. Moving into the fall, teachers will take part in a Community of Practice, where they will work to implement a place-based, data-rich moment in their individual classrooms. In the summer of 2025, teachers will take part in a second summer institute where they will continue to learn more about implementing place-based, data-rich instruction.
The PLACES GMRI Summer Institute was made possible by a large co-design, collaborative effort across our partner organizations. This included:
Facilitation Team: Catherine Bursk (GMRI), Meggie Harvey (GMRI), Sara Salisbury (GMRI), Daniel Damelin (Concord Consortium) In-person Facilitation Support Team: Leigh Peake (GMRI), Karen Lionberger (WestEd), Kristin Hunter-Thomson (Dataspire), Angela Rizzi (NASA Langley) In-Person Team Member Participants: Janet Struble and Kevin Czaikowski (GLOBE, University of Toledo), Svetlana Darche (WestEd) Virtual Observers: Kirsten Daehler, Nicole Wong, Leticia Perez (WestEd), Tracy Ostrom (GLOBE, UC Berkeley), Lori Rubino-Hare (NAU) Additional support: Frieda Reichsman (Concord Consortium), Barbie Buckner and Jessia Taylor (NASA Langley), Sean Ryan (NAU), Lauren Shollenberger (NAU) PLACES is supported by NASA under cooperative agreement award number 80NSSC22M0005 and is part of NASA’s Science Activation Portfolio.
