The two CubeSat passengers aboard ESA’s Hera mission for planetary defence have exchanged their first signals with Earth, confirming their nominal status. The pair were switched on to check out all their systems, marking the first operation of ESA CubeSats in deep space.

The NASA Ames Science Directorate recognizes the outstanding contributions of (pictured left to right) America Reyes Wang, Sepideh Khajehei, Julie Nottage, and Ryan Felton. Their commitment to the NASA mission represents the talent, camaraderie, and vision needed to explore this world and beyond.
Space Biosciences Star: America Reyes Wang
America Reyes Wang serves as the Space Biology Biospecimen Sharing Program (BSP) Lead in the Space Biosciences Research Branch, where she guides a team of support scientists and a logistics coordinator in planning and performing detailed, collaborative dissections to maximize the scientific return from biological investigations. Under her leadership, the BSP team has contributed over 5,000 samples to the NASA Biological Institutional Scientific Collection (NBISC), approximately half of which were collected in the last 10 months.
Earth Science Star: Sepideh Khajehei
Sepideh Khajehei is a NASA Earth eXchange (NEX) Data and Research Scientist in the Biospheric Science Branch, for the Bay Area Environmental Research Institute. She is recognized for her dedicated support of the NASA Administrator’s Earth Information Center, and recently for her outstanding support for an urgent request to revise climate indices just days before the October 7, 2024, opening of NASA’s Hometown Climate Dashboard at the Smithsonian Institute in Washington, D.C.
Space Science & Astrobiology Star: Julie Nottage
Julie Nottage continuously goes above and beyond in her role as the Space and Earth Sciences Facilities Service Manager. She keeps a multi-use interdisciplinary science building running across all aspects of operations and is the go-to person for any problem. Her can-do approach and wealth of knowledge ensures the facility’s high-quality operation that enables scientists and engineers to focus on their research and instrument work. Her quality work and extensive coordination of the Voluntary Protection Program allowed these month-long inspections to run smoothly with an improved safety outcome.
Space Science & Astrobiology Star: Ryan Felton
Ryan Felton, a NASA Postdoctoral Management Fellow with the Exobiology Branch, is recognized for his successful coordination of an engaging community-wide seminar series focused on Artificial Intelligence/Machine Learning (AI/ML). This seminar series featured four speakers so far over six months on a variety of exciting topics to advance AI/ML knowledge and use in the branch’s research.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Harvest Moon refers to the nearest full Moon to the autumnal equinox. The Moon appeared full for about three days last month from the evening of Monday, Sept. 16, through Thursday morning, Sept. 19. The brightest Moon was on Sept. 17.
NASA’s Glenn Research Center photographers captured images of this supermoon as it shone across Cleveland. Here’s how they described it:
“Complex.” Sara Lowthian-Hanna captured this composite image of the Moon above a Guardians of Traffic statue near downtown Cleveland. The Sept. 17 Harvest Moon had a lot going on: it was full, a supermoon, and experienced a partial lunar eclipse (when the Earth’s shadow falls upon the Moon’s surface). Credit: NASA/Sara Lowthian-Hanna “Shy.” Quentin Schwinn patiently waited for the Moon to peek out from behind clouds above the hangar at NASA’s Glenn Research Center. He took this shot just as a plane whizzed in front of the face of the Moon.

The day began with an 85% chance that bad weather would cause a launch delay: it ended with ESA’s Hera mission successfully in space and en route to the Didymos binary asteroid system.
At 16:52 CEST (14:52 UTC) on 7 October 2024, Hera took to the skies aboard a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station in Florida, USA. After a smooth 76-minute ascent, the spacecraft separated from its launcher, and, a few minutes later, ESA’s ESOC mission operations centre in Germany assumed control of the spacecraft.
Here is what has happened since then.

Video: 00:04:05 ESA’s Hera mission lifted off on a SpaceX Falcon 9 from Cape Canaveral Space Force Station in Florida, USA, on 7 October at 10:52 local time (16:52 CEST, 14:52 UTC).
Hera is ESA’s first planetary defence mission. It will fly to a unique target among the 1.3 million asteroids in our Solar System – the only body to have had its orbit shifted by human action – to solve lingering unknowns associated with its deflection.
Hera will carry out the first detailed survey of a ‘binary’ – or double-body – asteroid, 65803 Didymos, which is orbited by a smaller body, Dimorphos. Hera’s main focus will be Dimorphos, whose orbit around the main body was previously altered by NASA’s kinetic-impacting DART spacecraft.
By sharpening scientific understanding of this ‘kinetic impact’ technique of asteroid deflection, Hera should turn the experiment into a well-understood and repeatable technique for protecting Earth from an asteroid on a collision course.
