“Yes. I see it very, very clearly and very strongly. It was about truth and fairness and honesty and respect for others, no matter who they were or what strange alien creature they looked like. That was immaterial. They were alive. And if they needed help, Jean-Luc Picard and his crew, his team, were there to give it. So, yes, in a sense, we were ministers. And I have heard now so many times from individuals who have been honest enough and brave enough to tell me aspects of their life, of their health, of their mental health, and how it was all saved and improved by watching every week.”
-Actor Patrick Stewart in an interview with NPR responding to a question about whether he has noticed the fans’ religion-like reverence for Star Trek: The Next Generation. The conversation follows the release of Mr. Stewart’s new memoir, Making It So.

The image this week is what the International Space Station might see if it were traveling over Mars. Instead, this is the view of NASA’s Mars Odyssey orbiter.
You can learn more about this image by watching this video with Laura Kerber, deputy project scientist for NASA’s Mars Odyssey orbiter. You can also read more about the orbiter’s mission and the video of Phobos by visiting this NASA site.

I listened to a recent Cool Worlds Lab podcast where Professor David Kipping interviewed Professor Malena Rice from Yale University’s Department of Astronomy. The episode, titled Planet Nine, Oumuamua, Misaligned Exoplanets, covered a good range of topics, as the title suggests.
Of greatest interest to me was the continued search for a ninth planet in our solar system (sorry, Pluto). Professor Rice was noncommittal on the likelihood of such a planet, but she is hoping NASA’s Transiting Exoplanet Survey Satellite (TESS) can help to bring more light to the topic.
She discussed how this ninth planet is estimated to be a sub-Neptune sized planet, which appears to be common in many other solar systems we have observed. Planet Nine is estimated to be a gas giant about 5-10 times the mass of Earth yet smaller than Neptune lying 300-800 astronomical units from the Sun (or about 10 times more distant that Pluto).
Professor Rice noted that it is pretty amazing that we can discover distant galaxies but not potential planets in our backyard. She attributes this difficulty to the lack of light on such a planet.
The podcast episode dives deep in this topic, and then continues into other fascinating topics such as visitors to our solar system and strange solar systems elsewhere. It is a lot to take in, but well worth the time even if you need to play it more than once.
Note: Of course, it may not be a planet at all. One theory is that it is a black hole at the edge of our solar system. I would like to hear that podcast as well.
Planets with radii between that of the Earth and Neptune (hereafter referred to as ‘sub-Neptunes’) are found in close-in orbits around more than half of all Sun-like stars. However, their composition, formation and evolution remain poorly understood. The study of multiplanetary systems offers an opportunity to investigate the outcomes of planet formation and evolution while controlling for initial conditions and environment. Those in resonance (with their orbital periods related by a ratio of small integers) are particularly valuable because they imply a system architecture practically unchanged since its birth. Here we present the observations of six transiting planets around the bright nearby star HD 110067. We find that the planets follow a chain of resonant orbits. A dynamical study of the innermost planet triplet allowed the prediction and later confirmation of the orbits of the rest of the planets in the system. The six planets are found to be sub-Neptunes with radii ranging from 1.94R⊕ to 2.85R⊕. Three of the planets have measured masses, yielding low bulk densities that suggest the presence of large hydrogen-dominated atmospheres.

The Japanese government has said it will establish a $6.6 billion (¥1 trillion) fund to develop the country’s space industry as programs in the U.S., Russia, China and India rush to put men on the moon, build lunar sites and plan for the future of the International Space Station in a renewed race for celestial supremacy...Nikkei, a Japanese newspaper, reported that funding will be given to companies developing technologies that could be used to support national security or those that could rival Elon Musk’s SpaceX by developing rockets and “satellite constellations”—groups of satellites that operate as one system.
With just two Starship integrated test flights under its belt, SpaceX announced last week it is already working on a major overhaul of its second-stage Starship vehicle. The design changes will be significant enough to speciate the ship, giving it the title of Version 2. SpaceX plans to finish and launch four or five additional Starship V1 prototypes before transitioning to its V2 product line, Elon Musk said on X. Insights gained from the upcoming flights will be integrated into the next-gen rocket.
When the US imposed sanctions to degrade Russia’s aerospace industry, including embargoes on semiconductors, lasers, sensors, and navigation equipment, Dmitry Rogozin, then chief of Russia’s space program, warned it might cause the International Space Station to fall on the US or Europe. These comments and others from a supposedly serious scientific organization did cause a crash — the decades-old US-Russia space partnership was effectively ended after decades of joint work, including the Soviet era, that had benefited science, détente, and humanity. The events of 2022-2023 have made it more likely Russia would step away from exploration and, with China, focus on military applications in space.
