NASA Just Picked New Planetary Missions to Study. Here Are The Most Exciting Ones

At time of writing, there are eight active probes on or orbiting Mars.

Other Solar System planets have their secrets too, and NASA has just funded a bunch of planetary mission concept studies to see what's feasible to explore in the near future.

These studies will be published in the 2023 Planetary Science Decadal Survey, a US National Research Council publication produced every 10 years or so, identifying key issues and outlining recommendations for the coming decade in planetary science.

Not all of the concept studies will be selected to be developed into full missions; and then, not all the selected missions will end up being fully developed!

A Mars mission concept from the 2013 survey, for instance, was cancelled .

What is the difference between a planet-satellite system as we have with the Earth and Moon, versus a binary planet – two planets orbiting each other in a cosmic do-si-do?

In 2018, two astronomers from Columbia University reported the first tentative observation of an exomoon – a satellite orbiting a planet that itself orbits another star. One curious feature was that this exomoon Kepler-1625b-i was much more massive than any moon found in our solar system! NASA Just Picked New Planetary Missions to Study. Here Are ...galacticconnection.com/ ...study-here...This, according to planetary physicist Abigail Rymer of Johns Hopkins University and colleagues, is an issue that needs to be addressed. They propose a flagship mission to the outer Solar System to study not just Neptune, but its moon Triton – the only moon in the Solar System to orbit its planet against the planet 's rotation.!! It has a mass similar to Neptune and orbits a planet similar in size to Jupiter.

Astronomers expect moons of planets like Jupiter and Saturn to have masses only a few percent of Earth. But this new exomoon was almost a thousand times larger than the corresponding bodies of our solar system – moons like Ganymede and Titan which orbit Jupiter and Saturn, respectively!

To Find Baby Planets, Researchers Chase Waterfalls of Gas | Smart News |

Since researchers discovered the first exoplanets in the 1990s , astronomers have gotten pretty good at finding satellites orbiting distant suns, cataloguing 4,000 planets in more than 3,000 planetary systems since then. Now, researchers are interested in learning how these planets form, and a new technique may help them find hard-to-locate baby planets.

Young stars often have a disk of gas and dust swirling around them. Planets typically coalesce from this material, and eventually grow large enough to clear a path through these protoplanetary disks . But researchers aren’t certain that all of the gaps they’ve found actually come from young planets! Flipboard: NASA Just Picked New Planetary Missions to ...study...Space. NASA Just Picked New Planetary Missions to Study. Here Are The Most Exciting Ones. ScienceAlert - Michelle Starr. Look, Mars is great. It's full of great rocks, and those blue sunsets are just top-notch.!! That’s why a team recently looked at these disks in a new way, as they describe in a new study published in the journal Nature .

Astrophysicist Richard Teague, who conducted the study at the University of Michigan, and his team examined new high-resolution data from the Atacama Large Millimeter Array (ALMA), a radio observatory in Chile. In particular, they were able to observe the velocity of carbon monoxide gas moving within the protoplanetary disc around a young star called HD 163296. While hydrogen makes up the majority of the gas in the disk, carbon monoxide emits the brightest wavelengths, giving researchers the most detailed picture of how gas moves within the disk.

Another Pluto? What the discovery of a new dwarf planet means to astronomy | Salon.com

Ceres, Eris, Makemake, Haumea, and Pluto are expected to have a new friend, Hygiea, inducted into our solar system’s dwarf planet club. Hygiea was long believed to be a large asteroid in the asteroid belt, but has met all the requirements needed to become a dwarf planet thanks to new observations made by Chile’s Very Large Telescope (VLT).

The findings and new images that suggest Hygiea is actually a dwarf planet were published in Nature Astronomy by astronomer Pierre Vernazza of the Laboratoire d’Astrophysique de Marseille in France and his team of researchers.

“Thanks to the unique capability of the SPHERE instrument on the VLT , which is one of the most powerful imaging systems in the world, we could resolve Hygiea’s shape, which turns out to be nearly spherical,” Vernazza  said in a media statement . “Thanks to these images, Hygiea may be reclassified as a dwarf planet, so far the smallest in the Solar System.”

While you're here, how about this:

Symphony and Site celebrate 70 Years with The Planets | East Idaho News

IDAHO FALLS — As the Idaho Falls Symphony's 70th Season Jubilee continues, they proudly join forces with the Idaho National Laboratory, which is also celebrating their 70th year in Idaho Falls. The two organizations will collaborate to offer educational displays related to INL's space batteries program and more during the upcoming concert performance of The Planets, the beloved orchestral suite by English composer Gustav Holst. The concert will take place in the newly renovated Civic Center for the Performing Arts on Saturday, Nov. 9, at 7:30 p.m.

The first half of the program will feature the spirited and comic tone poem Till Eulenspiegel's Merry Pranks by Richard Strauss. This will be the first performance of a Strauss tone poem in the orchestra's 70 year history–a major milestone. Strauss is notorious for using large orchestral forces in his music, notably in the tone poem Zarathustra, made famous in the opening credits of 2001: A Space Odyssey. Here Strauss uses the huge orchestra to describe the "merry pranks" of his protagonist, the German medieval character Till Eulenspiegel, as he gets into all kinds of mischief. Music Director Thomas Heuser will lead audiences "Inside the Score" during the concert, with the orchestra providing musical examples of the different characters and scenes in real-time as a prelude to the complete performance.

Lessons from scorching hot weirdo-planets

Illustration of a hot Jupiter planet in the Messier 67 star cluster. Hot Jupiters are so named because of their close proximity — usually just a few million miles — to their star, which drives up temperatures and can puff out the planets.

* * *

Hot Jupiters were the first kind of exoplanet found. A quarter-century later, they still perplex and captivate — and their origins hold lessons about planet formation in general.

In 1995, after years of effort, astronomers made an announcement: They'd found the first planet circling a sun-like star outside our solar system. But that planet, 51 Pegasi b, was in a quite unexpected place — it appeared to be just around 4.8 million miles away from its home star and able to dash around the star in just over four Earth-days. Our innermost planet, Mercury, by comparison, is 28.6 million miles away from the sun at its closest approach and orbits it every 88 days.
