“I think that’s what’s so special about this film, and why people are having such an emotional connection to it … it’s like we’ve been so saturated with dystopia in future narratives for the last decade to the point where it feels almost inevitable at this point. Then you have Andy sort of reminding us through his work that human beings are always making the impossible possible.”
-Statement by Ryan Gosling, star of the upcoming film Project Hail Mary, in an interview with Scary Mommy. He was interviewed along with author Andy Weir.

Here are some recent space-related stories of interest.
In November 2021, NASA launched the Double Asteroid Redirection Test (DART) aimed at finding out whether or not we could redirect the trajectory of a near-Earth object simply by crashing into it…The mission was a success, making it the first time a human-made object has altered a celestial body’s path around the sun, but it would take more time to find out the magnitude of the success. Now, two years later, NASA scientists have calculated that DART’s collision with Dimorphos shortened the orbit of both asteroids by around 33 minutes.
Researchers working with the Lunar Reconnaissance Orbiter Camera found one such crater by comparing detailed photographs of the same lunar locations taken at different times. By examining images captured before December 2009 and others taken after December 2012, they were able to narrow down when the impact occurred, even though no one actually observed the collision. The crater measures 22 meters in diameter, comparable to a large house. What makes it particularly striking is not its size but its brightness. The collision ejected material tens of meters from the crater rim, creating distinctive rays that spread outward in a sunburst pattern. This bright, fresh material contrasts sharply with the surrounding darker regolith, making the crater stand out like a new freckle on familiar skin.
A new private space observatory, the Lazuli Space Telescope, is on track to surpass Hubble with its larger mirror and cutting-edge technology. Funded by former Google CEO Eric Schmidt and his wife Wendy, the project is already turning heads in the space community…At its core, Lazuli’s three-meter mirror will make it one of the largest space telescopes ever built, capable of observing both optical and infrared light.
The long-awaited second feature film of a book by author Andy Weir is almost here. After enjoying both the book and later movie-version of The Martian back in 2015 (yes, more than a decade ago), we are ready for his next film based on his 2021 book ProjectHailMary. Now you only have to wait until March 20th
Ryland Grace is the sole survivor on a desperate, last-chance mission—and if he fails, humanity and the earth itself will perish.
Except that right now, he doesn’t know that. He can’t even remember his own name, let alone the nature of his assignment or how to complete it.
All he knows is that he’s been asleep for a very, very long time. And he’s just been awakened to find himself millions of miles from home, with nothing but two corpses for company.
His crewmates dead, his memories fuzzily returning, Ryland realizes that an impossible task now confronts him. Hurtling through space on this tiny ship, it’s up to him to puzzle out an impossible scientific mystery—and conquer an extinction-level threat to our species.
And with the clock ticking down and the nearest human being light-years away, he’s got to do it all alone.
Or does he?
Basically, this story is about a lone astronaut that survives his peers on a long journey to save Earth only to encounter a sole-survivor, spider-like creature that can help him save Earth. This story might remind you of a 2024 film called Spaceman with Adam Sandler about a lone cosmonaut who travels far from Earth to meet with a spider-like creature. This creature is the sole survivor of a sickness but still able to find a way for Adam Sandler’s character to save Earth.
I’m not saying you have seen this movie before, but..
If you are interested in the story and science behind it, you might want to listen to an interview with the author on the Planetary Radio podcast.Andy Weir probably goes too far into the science, but it’s a good chance to dig a little deeper into the background of his book.
Aeon always has some great articles every month, and one of these is titled “The Snowball Effect.”
The article discusses two periods when glaciers covered the Earth from pole to equator. The last time was 645 million years ago, with the ice remaining for about 10 million years. Even so, life survived and diversified under these conditions on a super-continent called Rodinia.
It may offer some lessons to us when we are looking at our Solar System’s moons as well as distant exoplanets wondering about the presence of life beneath a frozen surface. If the Earth was a snowball for millions of years before life as we know it came to be, it makes sense it would be the case elsewhere.
I recommend you review this article as well as others on Aeon. It is worth your time.
Young exoplanets provide vital insights into the early dynamical and atmospheric evolution of planetary systems. Many multi-planet systems younger than 100 Myr exhibit mean-motion resonances, probably established through convergent disk migration. Over time, however, these resonant chains are often disrupted, mirroring the Nice model proposed for the Solar System. Here we present a detailed characterization of the ~200-Myr-old TOI-2076 system, which contains four sub-Neptune planets between 1.4 and 3.5 Earth radii. We demonstrate that its planets are near to but not locked in mean-motion resonances, making the system dynamically fragile. The four planets have comparable core masses but display a monotonic increase in hydrogen and helium (H/He) envelope mass fractions (from stripped to 1%, 5% and 5%) with decreasing stellar insolation. This trend is consistent with atmospheric mass loss due to photoevaporation, which predicts that the envelopes of irradiated planets either erode completely or stabilize at a residual level of ~1% by mass within the first few hundred million years, with more distant, less-irradiated planets retaining most of their primordial envelopes. Additionally, previous detections of metastable helium outflows rule out a pure water-world scenario for the TOI-2076 planets. Our finding provides direct observational evidence that the dynamical and atmospheric reshaping of compact planetary systems begins early and offers an empirical anchor for models of their long-term evolution.
