Video: 00:15:30 Meet Arnaud Prost—aerospace engineer, professional diver, and member of ESA’s Astronaut Reserve. From flying aircraft to getting a taste of spacewalk simulation, his passion for exploration knows no bounds.
In this miniseries, we take you on a journey through the ESA Astronaut Reserve, diving into the first part of their Astronaut Reserve Training (ART) at the European Astronaut Centre (EAC) near Cologne, Germany. Our “ARTists” are immersing themselves in everything from ESA and the International Space Station programme to the European space industry and institutions. They’re gaining hands-on experience in technical skills like spacecraft systems and robotics, alongside human behaviour, scientific lessons, scuba diving, and survival training.
ESA’s Astronaut Reserve Training programme is all about building Europe’s next generation of space explorers—preparing them for the opportunities of future missions in Earth orbit and beyond.
This interview was recorded in November 2024.

Hubble Spots a Chance Alignment
This NASA/ESA Hubble image features the spiral galaxy NGC 5530. ESA/Hubble & NASA, D. Thilker The subject of today’s NASA/ESA Hubble Space Telescope image is the stunning spiral galaxy NGC 5530. This galaxy is situated 40 million light-years away in the constellation Lupus, the Wolf, and classified as a ‘flocculent’ spiral, meaning its spiral arms are patchy and indistinct.
While some galaxies have extraordinarily bright centers that host a feasting supermassive black hole, the bright source near the center of NGC 5530 is not an active black hole but a star within our own galaxy, only 10,000 light-years from Earth. This chance alignment gives the appearance that the star is at the dense heart of NGC 5530.
If you pointed a backyard telescope at NGC 5530 on the evening of September 13, 2007, you would have seen another bright point of light adorning the galaxy. That night, Australian amateur astronomer Robert Evans discovered a supernova, named SN 2007IT, by comparing NGC 5530’s appearance through the telescope to a reference photo of the galaxy. While it’s remarkable to discover even one supernova using this painstaking method, Evans has in fact discovered more than 40 supernovae this way! This particular discovery was truly serendipitous: it’s likely that the light from the supernova completed its 40-million-year journey to Earth just days before Evans spotted the explosion.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Double Asteroid Redirection Test required extreme precision in mission planning to achieve its mission of impacting an asteroid. The founders of Continuum Space worked on astrodynamics relating to this mission, which they used to inform their product.NASA Planning space missions is a very involved process, ensuring orbits are lined up and spacecraft have enough fuel is imperative to the long-term survival of orbital assets. Continuum Space Systems Inc. of Pasadena, California, produces a cloud-based platform that gives mission planners everything they need to certify that their space resources can accomplish their goals.
Continuum’s story begins at NASA’s Jet Propulsion Laboratory in Southern California. Loic Chappaz, the company’s co-founder, started at JPL as an intern working on astrodynamics related to NASA’s Double Asteroid Redirection Test. There he met Leon Alkalai, a JPL technical fellow who spent his 30-year career at the center planning deep space missions. After Alkalai retired from NASA, he founded Mandala Space Ventures, a startup that explored several avenues of commercial space development. Chappaz soon became Mandala’s first employee, but to plan their future, Mandala’s leadership began thinking about the act of planning itself.
Because the staff had decades of combined experience at JPL, they knew the center had the building blocks for the software they needed. After licensing several pieces of software from JPL, the company began building planning systems that were highly adaptable to any space mission they could come up with. Mandala eventually evolved into a venture firm that incubated space-related startups. However, because Mandala had invested considerably in developing mission-planning tools, further development could be performed by a new company, and Continuum was fully spun off from Mandala in 2021.
Continuum’s platform includes several features for mission planners, such as plotting orbital maneuvers and risk management evaluations. Some of these are built upon software licensed from the Jet Propulsion Laboratory.Continuum Space Systems Inc. Continuum’s tools are designed to take a space mission from concept to completion. There are three different components to their “mission in a box” — design, build and test, and mission operations. The base of these tools are several pieces of software developed at NASA. As of 2024, several space startups have begun planning missions with Continuum’s NASA-inspired software, as well as established operators of satellite constellations. From Continuum to several startups, NASA technologies continue to prove a valuable foundation for the nation’s space economy.
