Photographer Steve Rice had fantasized about taking such pictures for years before a Cygnus cargo resupply mission created the perfect opportunity.

NASA to Provide Coverage of 71st International Astronautical Congress
NASA will broadcast key events, including an Artemis program update, of the 71st International Astronautical Congress (IAC), which takes place virtually Monday, Oct. 12, through Wednesday, Oct. 14. Coverage will air on NASA Television and the agency’s website.
During the conference, NASA will discuss international cooperation for the agency’s lunar exploration plans throughout the Artemis program, which includes sending American astronauts to the surface of the Moon in 2024 and establishing a sustainable lunar presence by the end of the decade.
In addition to participation in events outlined below, NASA will have a virtual exhibit featuring information on Artemis, NASA’s Commercial Crew Program, and the International Space Station. Visitors also will have an opportunity to contribute to a digital mosaic of the space station on social media using #NASAVirtualExhibit.
This week on the Cosmic Controversy podcast
I’m excited to welcome Catherine Johnson, a planetary geophysicist at the University of British Columbia in Vancouver, a senior scientist at the Planetary Science Institute in Tucson, Arizona and an expert on the planet Mercury; the innermost planet in our solar system. Spacecraft have only visited Mercury twice, via flyby and orbit. But in 2025, a European mission is scheduled to orbit this puzzling planet with two separate spacecraft and should help further lift the scientific veil on this tiny world. Catherine and I will be talking all things Mercury! Stay tuned.
Physicists Just Confirmed The Upper Limit For The Speed of Sound in The Universe
Einstein’s theory of special relativity gave us the speed limit of the Universe — that of light in a vacuum. But the absolute top speed of sound, through any medium, has been somewhat trickier to constrain.
It’s impossible to measure the speed of sound in every single material in existence, but scientists have now managed to pin down an upper limit based on fundamental constants, the universal parameters by which we understand the physics of the Universe.
That speed limit, according to the new calculations, is 36 kilometres per second (22 miles per second). That’s about twice the speed of sound travelling through diamond.
A New Factory in France Will Mass-Produce Bugs as Food
It looks like our food for the future will be bugs. A factory in France will grow bugs as a food source.
Enter the insects. Or, more appropriately in this case, enter Ÿnsect, the French company with big ambitions to help change the way the world eats. Ÿnsect raised $125 million in Series C funding in early 2019, and at the time already had $70 million worth of aggregated orders to fill. Now they’re building a bug-farming plant to churn out tiny critters in record numbers.
You’ve probably heard of vertical farms in the context of plants; most existing vertical farms use LED lights and a precise mixture of nutrients and water to grow leafy greens or other produce indoors. They maximize the surface area used for growing by stacking several layers of plants on top of one another; the method may not make for as much space as outdoor fields have, but can yield a lot more than you might think.
Ÿnsect’s new plant will use layered trays too, except they’ll be cultivating beetle larvae instead of plants. The ceilings of the facility are 130 feet high—that’s a lot of vertical space to grow bugs in. Those of us who are grossed out by the thought will be glad to know that the whole operation will be highly automated; robots will tend to and harvest the beetles, and AI will be employed to keep tabs on important growing conditions like temperature and humidity.
Astronomers produce largest 3D catalog of galaxies
A team of astronomers at the University of Hawaiʻi at Mānoa Institute for Astronomy (IfA) has produced the world’s largest three-dimensional astronomical imaging catalog of stars, galaxies and quasars. The team used data from UH’s Panoramic Survey Telescope and Rapid Response System or Pan-STARRS1 (PS1) on Haleakalā. The PS1 3π survey is the world’s largest deep multi-color optical survey, spanning three-quarters of the sky. IfA astronomers applied novel computational tools to the catalog, to decipher which of the 3 billion objects are stars, galaxies or quasars. For the galaxies, the software also derived estimates of their distances.
The resulting 3D catalog is now available as a high-level science product through the Mikulski Archive for Space Telescopes. It is approximately 300 GB in size, and science users can query the catalog through the MAST CasJobs SQL interface, or download the entire collection as a computer-readable table.
Episode 19 — Cracking The Code On Mercury, Our Solar System’s Innermost Mystery
Great new podcast episode on our strange planet Mercury with planetary geophysicist Catherine Johnson, who eloquently explains what’s known about our tiny, innermost planet’s many remaining mysteries. Please have a listen.
Guest Catherine Johnson, a planetary geophysicist at the University of British Columbia in Vancouver, discusses this bizarre little world; the innermost planet in our solar system. A planet that’s so close to our Sun that its surface temperatures can hit 800 F. But surprisingly, its poles harbor enough water ice to completely bury a major metropolis. Some have even argued that Mercury may have once been habitable. Where it formed still remains a mystery, but it does have a tiny magnetic field, a very oversized iron core, and one of the largest impact basins in the solar system. A European mission is currently en route to orbit the planet in 2025.
