SpaceX Aims for Stellar Reentry: Ensuring Safety of Starship Megarocket for a Successful Launch
SpaceX focuses on secure reentry of Starship Megarocket, maximizing safety for an explosive-free launch.
In the ambitious journey towards a fully reusable spacecraft capable of transporting humans and cargo to Earth orbit, the Moon, Mars, and beyond, SpaceX is gearing up for another critical test flight of its Starship rocket. The fourth fully integrated test flight (IFT-4) is slated for next week, pending regulatory approval, with a primary focus on demonstrating safe reentry and landing capabilities—if everything goes as planned.
Preparations and Milestones
SpaceX’s fourth test flight aims to achieve new milestones, potentially launching on the morning of Wednesday, June 5, from Texas. This follows the Federal Aviation Administration’s (FAA) completion of its safety investigation into the third flight, finding no public safety concerns. This clears the path for the FAA to issue the next launch license. Additionally, SpaceX completed its second wet dress rehearsal on May 23, using prototype stages Booster 11 and Ship 29, signifying readiness for the upcoming mission.
Lessons from Previous Flights
The third integrated flight test of Starship on March 14 marked significant progress. It featured a successful stage separation, a full-duration burn of the second-stage engines, an internal propellant-transfer demonstration for NASA, and a test of the Starlink dispenser door. Despite the upper stage disintegrating during reentry and the Super Heavy booster exploding 1,515 feet above the Gulf of Mexico due to engine shutdowns, the mission showed substantial improvements compared to the earlier tests, which both ended in premature explosions.
Goals of the Fourth Test
The IFT-4 mission shifts focus from achieving orbit to successfully returning both stages of the Starship. Primary objectives include executing a landing burn and soft splashdown of the Super Heavy booster in the Gulf of Mexico and achieving a controlled reentry of the Starship upper stage.
To enhance reliability, SpaceX has made several software and hardware upgrades. Changes include dropping the Super Heavy’s hot-stage adapter post-boostback burn to reduce weight for the final flight phase. This adapter allows the engines to remain ignited while the second stage separates and begins its burn. The upper stage is again targeting a splashdown in the Indian Ocean.
Key Aspects to Watch
Performance of the attitude control system will be crucial. In the third test, a filter blockage in this system caused a loss of control, resulting in unanticipated heating during reentry. SpaceX has since added more control redundancy and upgraded hardware to resist blockages. Observers will be keen to see how well the upper stage performs during its brief time in space and how its hexagonal heat-absorbing tiles fare during reentry.
A Step Towards a Reusable Future
SpaceX remains focused on rapidly developing the Starship to build a fully reusable transportation system. The company is keen to learn quickly from each test, continuously refining and improving its technology.
“The fourth flight of Starship will aim to bring us closer to the rapidly reusable future on the horizon,” SpaceX stated. “We’re continuing to rapidly develop Starship, putting flight hardware in a flight environment to learn as quickly as possible.”
As the world watches, the upcoming flight promises to provide stunning views of Earth and the Starship, along with insights into SpaceX’s progress. Each test flight brings its successes and challenges, and while the outcome remains uncertain, it’s certain to be an exciting and informative spectacle.

Artemis II crew brought a human eye and storytelling vision to the photos they took on their mission
Artemis II crew: Artemis II’s astronaut photos show how human perspective and storytelling make space imagery feel authentic—especially in an era of AI-generated visuals.
Christye Sisson, Rochester Institute of Technology
In early April 2026, the Artemis II mission captivated me and millions of people watching from across the world. The crew’s courage, skill and infectious wonder served as tangible proof of human persistence and technological achievement, all against the mysterious backdrop of space.
People back on Earth got to witness the mission through remarkable photos of space captured by astronauts. Images created and shared by astronauts underscore how photography builds a powerful, authentic connection that goes beyond what technology alone can capture.
As a photographer and the director of the Rochester Institute of Technology’s School of Photographic Arts and Sciences, I am especially drawn to how these photographs have been at the center of the public’s collective experience of this mission.
In an era when image authenticity is often questioned and with the capabilities of autonomous, AI-driven imaging, NASA’s choice to train astronauts in photography has placed meaning over convenience and prioritized their human perspectives and creativity.
Capturing space from the crew’s perspective
Photography was not originally placed as a high priority in NASA’s Apollo era. The astronauts only took photographs if they had the chance and all their other tasks were complete.
Thanks largely in part to public response to those images from Apollo, including “Earthrise” and the “Blue Marble” being widely credited for helping catalyze the modern environmental movement, NASA shifted its approach to utilize photography to help capture the public’s imagination by training their astronauts in photographic practices.
The Artemis II mission’s photographs have helped cut through the increasing volume of artificially generated images circulating on social media. NASA’s social media releases of the crew’s photographs have garnered thousands of shares and comments.
This excitement could be explained by the novelty of photos from space, but these images also distinguish themselves as products of astronauts experiencing these sights and interpreting them through their photographs. These differences require an important distinction around where technology ends and humanity begins.
Human perspective versus AI tools
Photography has long integrated AI-powered software and data-driven tools in a variety of ways: to process raw images, fill in missing color information, drive precise focus and guide image editing, among others. These modern technological assists help human photographers realize their vision.
Artificial intelligence is also increasingly capable of operating machinery competently and autonomously, from cars to drones and cameras.
And AI can generate convincing, realistic images and videos from nothing more than a text prompt, using readily available tools.
Researchers train AI to mimic patterns informed by millions of sample images, and the algorithm can then either take or create a photograph based on what it predicts would be the most likely version of a successful, believable image.
Human-created photos are rooted in direct observation, intent and lived experience, while AI images – or choices made by AI-driven tools – are not. While both can produce compelling and believable visuals, the human photographs carry emotional power because the photographer is drawing from their experiences and perspective in that moment to tell an authentic story.
Artemis II photographs resonate, not only because they are historic, but because they reflect the deliberate choices and intent of a human being in that specific moment and context. The exposure, camera setting, lens choice and composition are all dictated by the astronaut’s vision, skill, perspective and experience. Each image is unique in comparison with the others. These choices give the images narrative power, anchoring them in human perspective.
Images to tell a story
Photographers choose what to include in the final version of their image to tell a story. In the Artemis II images, this human perspective comes out. In the “Earthset” photo, you see a striking juxtaposition of the Moon’s monochromatic, textured surface in the foreground against a slivered, bright Earth.
The choice to include both in the frame contrasts these objects literally and figuratively, inviting comparison. It creates a narrative where Earth is contrasted against the Moon – life is contrasted against the absence of it.
Another photo shows the nightside of the whole Earth, featuring the Sun’s halo, auroras and city lights. The choice to include the subtle framing of the window of the capsule in the lower left corner reminds the viewer where and how this image was captured: by a human, inside a capsule, hurtling through space. That detail grounds the photograph in the human perspective.
Both photos are reminiscent of Earthrise and the Blue Marble. These past images hold a place in the global collective consciousness, shaped by a shared historical moment.
The Artemis II photographs are anchored in this collective moment of lived human experience, yet also shaped by each astronaut’s viewpoint. The crew’s unique perspectives exemplify photography’s transformative power by inviting viewers to engage emotionally and intellectually with their journey. These photographs share the astronauts’ awe and wonder and affirm the value of human creativity and its ability to connect us in a captured moment.

Seeing an eclipse from Earth is awe‑inspiring – for astronauts seeing one from space, the scene was even more grand
Discover the stunning eclipse seen by Artemis II astronauts during their 2026 Moon mission. A truly extraordinary spectacle awaits.
Deana L. Weibel, Grand Valley State University
The astronauts on Artemis II’s trip to the Moon in April 2026 didn’t just have an amazing journey through space. They also saw something extraordinary. They were the first humans to see a total solar eclipse from space.
A solar eclipse happens when the Moon moves in front of the Sun. In a total eclipse, the Sun’s central disc is covered completely.
From Earth, the circle of the Sun is about the same size as the circle of the Moon. With the bright circle blocked, you can see the undulating rays of the Sun’s corona, or outer atmosphere, that are normally too dim to be observed.
I’m a cultural anthropologist who studies awe-inspiring aspects of space exploration. I have been lucky enough to have seen two total solar eclipses. The first one was in Nebraska in 2017, the second in Indiana in 2024.
During my second total eclipse, the period of totality – that short span when you can remove your protective glasses and look directly at the eclipse – lasted close to 4 minutes. I saw waves of diffuse light snaking around an ink-black hole in the sky. It looked very wrong – almost alien.
On Aug. 12, 2026, there will be another total solar eclipse, visible only from Greenland, Iceland, Spain and the Balearic Islands of the Mediterranean. Some fortunate viewers in Spain and nearby islands may see the eclipse just before sunset, low on the horizon. The Moon illusion, a phenomenon where the Moon looks bigger when it’s near the horizon, might make this eclipse look unusually large.
Unusual eclipse perspectives
Astronauts will occasionally also have less common eclipse experiences. I interviewed one I call by the pseudonym “Jackie” in my research about astronauts’ experiences of awe. She was part of an astronaut training group that did a flight exercise during a total solar eclipse.
Jackie and her squad flew their jets in the shadow of the Moon. This lengthened their time in totality because they could follow and stay within the shadow. Jackie was most impressed with how the Sun’s corona seemed to shift and ripple.
“It’s not static … it’s alive,” she told me.
On April 6, 2026, the astronauts of NASA’s Artemis II mission saw another kind of unusual eclipse as they flew around the Moon. At one point during their flight, the Moon and the spacecraft aligned so that the Moon was directly between them and the Sun, blocking the Sun’s disk in a way that looks very different from what we see on Earth.
Astronaut Victor Glover said it felt like they “just went sci-fi.” https://www.youtube.com/embed/YLjPci5bo1k?wmode=transparent&start=0 ‘An impressive sight’: The Artemis II crew were the first humans to observe a solar eclipse from near the Moon.
The astronauts were so close to the Moon that the Moon looked bigger than the Sun and hid more of its bright circle. Earth was also in view, and sunlight reflected from the Earth onto the Moon in a phenomenon NASA calls “earthshine.” This dim light is very similar to the moonlight that shines on the Earth at night.
Imagine the Sun hidden behind the Moon, creating a hazy halo around the Moon’s edges. At the same time, faint light reflected from Earth softly illuminates the Moon, revealing mountains and craters in a dim twilight. Now imagine this striking scene lasting 54 minutes.
This sight was, without a doubt, one of the most unusual eclipses ever seen by human eyes.
Although Artemis’ astronauts are trained to think scientifically, this experience propelled them into a state of awe. They talked openly about how their brains were “not processing” what they observed. While NASA kept them busy with a variety of tasks, the sound of emotion and excitement in their voices as they broadcast live from their lunar flyby was unmistakable.
The psychology of awe
Researchers have studied the effects of awe on the human brain, including awe felt during solar eclipses. Moments of wonder like these can transform how you feel and even how you think, making you more thoughtful and open-minded.
In my own work I’ve found these experiences can change how astronauts understand their own place in the universe.
One astronaut said she gained an awareness of the fragility of our planet that now shapes everything she does, while another described becoming more curious after returning to Earth. A third said the awe he experienced in lunar orbit changed his understanding of time and infinity.
Space travel creates many opportunities for awe, but a solar eclipse from behind the Moon, as Mission Commander Reid Wiseman put it, required “20 new superlatives.”
It’s an experience most of the earthbound eclipse-chasers heading to Greenland or Iceland or Spain this summer will only dream about. Whether eclipses happen in space or on Earth, though, close encounters with the grandeur of our universe can make you feel profoundly human.
