ESA/Hubble & NASA, C. Kilpatrick This NASA/ESA Hubble Space Telescope image treats viewers to a wonderfully detailed snapshot of the spiral galaxy NGC 3430 that lies 100 million light-years from Earth in the constellation Leo Minor. Several other galaxies, located relatively nearby to this one, are just beyond the frame of this image; one is close enough that gravitational interaction is driving some star formation in NGC 3430 — visible as bright-blue patches near to but outside of the galaxy’s main spiral structure. This fine example of a galactic spiral holds a bright core from which a pinwheel array of arms appears to radiate outward. Dark dust lanes and bright star-forming regions help define these spiral arms.
NGC 3430’s distinct shape may be one reason why astronomer Edwin Hubble used to it to help define his classification of galaxies. Namesake of the Hubble Space Telescope, Edwin Hubble authored a paper in 1926 that outlined the classification of some four hundred galaxies by their appearance — as either spiral, barred spiral, lenticular, elliptical, or irregular. This straightforward typology proved extremely influential, and the detailed schemes astronomers use today are still based on Edwin Hubble’s work. NGC 3430 itself is a spiral lacking a central bar with open, clearly defined arms — classified today as an SAc galaxy.

Hubble Images a Classic Spiral

Crane operator Rebekah Tolatovicz, a shift mechanical technician lead for Artic Slope Regional Corporation at NASA’s Kennedy Space Center in Florida, operates a 30-ton crane to lift the agency’s Artemis II Orion spacecraft out of the recently renovated altitude chamber to the Final Assembly and Systems Testing, or FAST, cell inside NASA Kennedy’s Neil A. Armstrong Operations and Checkout Building on April 27.
During her most recent lift July 10, Tolatovicz helped transfer Orion back to the FAST cell following vacuum chamber qualification testing in the altitude chamber earlier this month. This lift is one of around 250 annual lifts performed at NASA Kennedy by seven operator/directors and 14 crane operators on the ASRC Orion team.
“At the time of the spacecraft lift, I focus solely on what’s going on in the moment of the operation,” explains Tolatovicz. “Listening for the commands from the lift director, making sure everyone is safe, verifying the vehicle is clear, and ensuring the crane is moving correctly.”
All Orion crane operators are certified after classroom and on-the-job training focusing on areas such as rigging, weight and center of gravity, mastering crane controls, crane securing, assessing safety issues, and emergency procedures. Once certified, they progress through a series of the different lifts required for Orion spacecraft operations, from simple moves to the complex full spacecraft lift.
“It’s not until after the move is complete and the vehicle is secured that I have a moment to think about how awesome it is to be a part of history on the Orion Program and do what I get to do every day with a team of the most amazing people,” Tolatovicz said.

Image: Concordia is a research station in Antarctica that places you farther away from humankind than even the International Space Station. Every year, ESA sponsors a medical doctor to spend a year, or "winterover," at Concordia station. This year, our medical doctor is Jessica Kehala Studer, who is seen in this picture gazing at the Moon and the vast expanse of Antarctica. Around May, the Sun dips below the horizon for the last time, and the crew experiences four months of total darkness, with temperatures dropping to –80°C in winter.
The station serves as an analogue for space, mirroring the challenges and conditions faced by astronauts such as isolation, extreme cold and darkness, along with their impact on health. Concordia is a unique platform for research in human physiology and psychology, as well as astronomy, meteorology, glaciology and other fields.
Last Saturday, we celebrated Moon Day: 55 years ago on 20 July 1969, humankind stepped on the Moon for the first time during the Apollo 11 mission. Today, ESA is a key part of NASA's Artemis programme which aims to return humans to the Moon. The insights gained from ESA's experience in analogue facilities such as Concordia will be invaluable for this mission.
