In Case You Missed It: One Way to Get Kids into Planetariums

It may be an unusual way to encourage children to visit a planetarium, but it seems to be working. Taylor Swift light shows appear to be the new rage at planetariums across the country.

The image above comes from the light show at the Saint Louis planetarium, though you can find similar shows at planetariums in Springfield, Massachusetts, Laramie, Wyoming, and Boulder, Colorado.

I suppose this is a way to introduce some kids to the existence of the planetarium while also paying the overhead for the planetarium itself. It would be nice to learn whether the same crowd comes back later to learn more about the solar system and universe, though I have not seen much press on that relationship.

One can only hope that the real stars eventually outshine the Earth-bound ones for some of these children. Maybe the visit will even lead to more interest in the planets, such as Saturn. After all, didn’t Taylor sing about that planet in her song Seven?

Sweet tea in the summer
Cross your heart, won’t tell no other
And though I can’t recall your face
I still got love for you
Your braids like a pattern
Love you to the moon and to Saturn
Passed down like folk songs
The love lasts so long

In Case You Missed It/Video: The Stakes Are High with Our Return to the Moon

With the recent glitches related to the two commercial Moon missions, an earlier NASA video on the Artemis program became all too relevant. In the video, “Farther and Faster: NASA’s Journey to the Moon with Artemis,” we hear that the stakes are high as we attempt to return to the Moon, and how we could be the generation that loses the Moon if we don’t get it right.

In addition to the risks, the video also highlights the great successes already with the Artemis I mission, as you may recall from back in 2022:

Over the course of 25.5 days, Orion performed two lunar flybys, coming within 80 miles (129 kilometers) of the lunar surface. At its farthest distance during the mission, Orion traveled nearly 270,000 miles (435,000 kilometers) from our home planet. On Dec. 11, 2022, NASA’s Orion spacecraft successfully completed a parachute-assisted splashdown in the Pacific Ocean at 9:40 a.m. PST (12:40 p.m. EST) as the final major milestone of the Artemis I mission.

Artemis I set new performance records, exceeded efficiency expectations, and established new safety baselines for humans in deep space. This is a prelude to what comes next—following the success of Artemis I, human beings will fly around the Moon on Artemis II.

It is worth pondering what we have ahead of us. NASA may be having a few issues with its commercial partners, but the main mission has done well. We cannot be discouraged with a few delays as long as we keep the course. We have done it before and there is no reason we cannot do it again. I say slow and steady.

Mars is the goal, but we need to prove ourselves with the Moon. Check out the video and determine for yourself if we have already made a fair amount of progress.

In Case You Missed It/Video: Missed Opportunity on Exomoons

A few months back, Assistant Professor of Astronomy David Kipping shared a short video regarding his organization’s failure to secure James Webb Space Telescope (JWST) time to search for exomoons that he knows are there. His organization, Cool Worlds Lab, has done some amazing work studying and publicizing issues related to astronomy. You should visit his site for some challenging topics.

What is unique about his video is that it was recorded only one hour after he learned that his organization would not be able to use JWST for his exomoon search and he wanted to share what rejection felt like “in real time.” He goes on to say that such rejection is part of science, as brutal as it may feel at the moment, noting that for every seven JWST proposals, only one will be approved.

Fortunately, we have scientists out there with very thick skin sharing new ideas and proposals. And Dr. Kipping will not be giving up on his exomoon push anytime soon. That is good news for all of us.

In Case You Missed It/Television: JWST on 60 Minutes

Last month 60 Minutes had a piece on the James Webb Space Telescope (JWST), titled The Origin of Everything, that provided viewers with more amazing images. I recommend the episode. I also plan to watch a few more times myself.

For a taste of the episode, here is Matt Mountain, who heads up JWST’s operations as president of the Association of Universities for Research in Astronomy, discussing the speckled images captured at the very start as engineers used a star to align the telescope’s 18 mirrors.

Matt Mountain: These were not artifacts from the detector. These were not strange stars. The whole of the sky was filled with galaxies. There was no empty sky. And that’s when I went, “This telescope’s going to be phenomenal.”

Scott Pelley: No empty sky? What do you mean by that?

Matt Mountain: On almost every image we’re taking now, we see galaxies everywhere. I mean, we took a simple picture of a planet in our own system, Neptune. You know, it was this beautiful orb just sitting there and we saw some rings. In the background are galaxies again. It tells us that our universe is filled with galaxies. We knew this theoretically but when you go out to the night sky, we’re used to saying, “Well, look up at the night sky, we see those stars.” We can no longer say that. We now have to say, “Look up at the night sky and there are galaxies everywhere.”

Scott Pelley: We call it space because we thought there was nothing out there.

Matt Mountain: There is no empty sky with James Webb. That is what we have discovered.

In Case You Missed It: More Trash, This Time on Mars

In an earlier post, I noted the amount of poop as well as other trash left behind on the Moon from prior lunar missions. Well, Cagri Kilic, a Postdoctoral Research Fellow at West Virginia University, also ventured a guess at the amount of human trash that has already accummulated on the surface of Mars.

In the article he authored for The Conversation back in September, “Mars is Littered with 15,694 Pounds of Human Trash from 50 Years of Robotic Exploration,” he provided a figure as well as his methodology:

When you add up the mass of all spacecraft that have ever been sent to Mars, you get about 22,000 pounds (9979 kilograms). Subtract the weight of the currently operational craft on the surface – 6,306 pounds (2,860 kilograms) – and you are left with 15,694 pounds (7,119 kilograms) of human debris on Mars.

That’s a fair amount of trash and defunct equipment. And we are still adding to this toll, with plans to eventually send humans and material for settlements to the Red Planet. The same goes for the Moon, with multiple bases planned by the US, China, and Russia.

I expect we will see some other estimates in the future on what has been left on other planets, moons, and asteroids. And let’s not forget the five spacecraft we have shot beyond Pluto.

We humans do tend to leave a mess where ever we go. We may be explorers, but Boy Scouts would take issue given their principle “Leave No Trace.”
