Here are some recent stories of interest.

—Space.com : “Mars is Spinning Faster and its Days are Getting Shorter. Scientists Aren’t Sure Why“

The length of Mars’ day is shortening by three-quarters of a millisecond each year as the planet’s rotation spins up, according to new results from NASA’s InSight lander…Planetary scientists are not entirely sure why this is happening, but it is likely related to the redistribution of Mars’ mass, which can have an effect on the planet’s rotation like an ice skater pulling in their arms to spin faster. This redistribution might be caused by the accumulation of ice on Mars’ polar caps, experts believe, or by the surface itself slowly rebounding from residing under the weight of immense glaciers that existed at equatorial latitudes during the world’s most recent ice ages, which ended about 400,000 years ago.

NASA has left the door open for changing the scope of Artemis 3, currently set to be the first crewed lunar landing of the program, if key elements suffer major delays. Speaking at an Aug. 8 briefing at the Kennedy Space Center, Jim Free, NASA associate administrator for exploration systems development, said the Artemis 3 mission still has a formal launch date of December 2025 but that he was monitoring potential delays in hardware needed for the mission. “We may end up flying a different mission if that’s the case,” he said. “If we have these big slips out, we’ve looked at if can we do other missions.” Artemis 3 could also change based on the outcome of Artemis 2, he added.

—ScienceNews.com : “A Star Cluster in the Milky Way Appears to be as Old as the Universe“

One of the oldest known objects in the universe is wandering around the Milky Way. Star cluster M92, a densely packed ball of stars roughly 27,000 light-years from Earth, is about 13.8 billion years old, researchers report in a paper submitted June 3 to arXiv.org. The newly refined age estimate makes this clump of stars nearly the same age as the universe. Refining the ages of clusters like M92 can help put limits on the age of the universe itself. It can also help solve cosmic conundrums about how the universe evolved.

Television: Singing with Star Trek

If you are following Star Trek: Strange New Worlds, then you may have already encountered episode 9 of the second season, titled “Subspace Rhapsody.” Should you have missed it, then you are in for a treat because this is the first Star Trek musical episode. And it is fun.

For just a taste, check out this clip with an emotional Spock singing his heart out. I do not want to give to much away and spoil the episode if you are not that far along in the series, but let’s just say Spoke is have relationship issues. You must admit that Ethan Peck has a nice voice, as do his crew mates singing other pieces.

The whole thing has the feeling of the Buffy the Vampire Slayer singing episode, which is fine with me given that I believe it was one of the better episodes of that show.

By the way, Spock also had a small singing part in the original series. In that case, he sang a serenade accompanied by a harp. It’s a short piece, yet enough to show that Mr. Peck beats Mr. Nimoy as a singer.

Last season, Strange New Worlds had the cast caught up in a children’s story. I did not find that one to be as enjoyable, but it was another attempt to have some fun with the series. I like the effort to keep it fresh.

Maybe another ballad could be fit into an episode down the road – maybe something similar to what The Orville did in its final two episodes. That too created two of the more memorable episodes of that series.

Space Quote: NASA Funding May Not Be What You Think It Is

Posted on by onespaceman2000

“While NASA’s programs are very popular and highly visible, we really don’t spend much on our space agency. In 2022, the U.S. treasury took in revenues of $4.9 trillion and then charged up another $1.4 trillion so it could spend a whopping $6.3 trillion. Of that largesse NASA received an historically generous appropriation of $24 billion. Still, that was just 0.35% of federal spending.”

-Statement by Greg Autry, Clinical Professor of Space Leadership, Policy & Business at Thunderbird School of Global Management, ASU, in a Forbes magazine article, “Pennywise, Future Foolish: Congress Moves To Cut NASA Science Budget.” As with foreign assistance, Americans tend to assume NASA has greater funding than it really has. At the same time, the majority of Americans want a strong space program.

Voyager 2 is Still Talking to Us

After two weeks with no word, Voyager 2 is back to communicating with us as it continues its journey beyond our solar system. The whole incident started when NASA sent a bad command, but all is well.

Voyager 2 first left Earth back in August 1977 and exited the solar system in December 2018. Like Voyager 1, which is also outside the solar system now, Voyager 2 had the initial task of studying the planets. Voyager 2 focused on Jupiter, Saturn, Uranus and Neptune. It has shown it was capable of much more as it dragged the human race to the bleeding edge of space.

You can read all about Voyager 2’s accomplishments at this NASA site, including:

  • Voyager 2 is the only spacecraft to study all four of the solar system’s giant planets at close range.
  • Voyager 2 discovered a 14th moon at Jupiter.
  • Voyager 2 was the first human-made object to fly past Uranus.
  • At Uranus, Voyager 2 discovered 10 new moons and two new rings.
  • Voyager 2 was the first human-made object to fly by Neptune.
  • At Neptune, Voyager 2 discovered five moons, four rings, and a “Great Dark Spot.”

An impressive list of accomplishments, and the spacecraft is still ticking as it goes into the great unknown.

We need to keep these achievements in mind as we battle over this year’s NASA budget. We also need to remember that there was supposed to be four Voyager-like spacecraft rather than two, but budget cuts nixed the second set. Meaning we can still get some great things done even if we don’t have the budget to fund every piece of a grand vision.
