Just in time for the Labor Day weekend, we are offered a new space film that seemed to have had little publicity until it popped onto the scene. The new film Slingshot, starting today and starring Casey Affleck and Laurence Fishburne, takes us on a trip to Saturn’s moon Titan, or that is the plan.

Here is the general story (and trailer):

A psychological thriller starring Casey Affleck and Laurence Fishburne, SLINGSHOT follows an elite trio of astronauts aboard a years-long, possibly compromised mission to Saturn’s moon Titan. As the team gears up for a highly dangerous slingshot maneuver that will either catapult them to Titan or into deep space, it becomes increasingly difficult for one astronaut to maintain his grip on reality.

The trailer indicates plenty of issues with both the hardware and software – the softest ware being the mind of man on a distant voyage. Yes, we have another story about the struggle of man with himself, with space playing a supporting actor.

Fortunately, we are not dealing with a film that questions the space program, but NASA may be pleased that it is sending a robot to study Europa rather than taking chances with such fragile humans.

Here are a few of the available reviews:

Austin Chronicle:

The derivative look and feel of Slingshot – a little bit of Interstellar, a dash of 2010: The Year We Make Contact for whenever Håfström wants to add some grit, and most especially Steven Soderbergh’s Solaris remake – make it unclear exactly what kind of movie Håfström is trying to make.

The Hollywood Reporter:

It’s fairly boilerplate material, and Håfström frankly seems more interested in exploring John’s memories, nightmares, visions and wavering psyche..If you put aside all the space stuff, Slingshot is basically a one-set, one-character thriller that constantly tests the viewer’s belief in what’s happening.

RogerEbert.com:

It feels like a movie that hates its characters. And hates you too.

Now the movie has some publicity, but maybe not the type it wanted.

Go for the special effects rather than the plot.

That might work.

Video: More About Rogue Planets

Cool Worlds Lab released another great video recently that discusses rogue planets, or planets without a host star, in a video titled “A JuMBO Mystery – This Shouldn’t Happen!”

A JuMBO means Jupiter-mass binary objects, which is just part of the story in this video. The presentation starts with a finding from astronomers using the James Webb Space Telescope, who identify 520 rogue planet candidates. This is interesting in itself, but the intriguing part is that a number of these planets are found in pairs. This would not make a lot of sense if we believed these planets were once within a solar system before being pushing into space.

The video discusses the various theories explaining these JuMBOs and rogue planets in general. It also discusses the potential impact on our own solar system, such as whether we lost one of our own planets in the past and/or a nearby rogue planet (and its moons) is out there today waiting to be discovered.

As always, Cool Worlds Lab keeps astronomy even more interesting.

Space Quote: Europa Clipper Mission Faces New Radiation Risk

“Engineers with NASA’s Europa Clipper mission continue to conduct extensive testing of transistors that help control the flow of electricity on the spacecraft. NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission, began the tests after learning that some of these parts may not withstand the radiation of the Jupiter system, which is the most intense radiation environment in the solar system.”

–NASA statement from yesterday regarding potential issues with electrical switches on the Europa Clipper spacecraft that is set to launch in October. Whether this leads to a delayed launch of the mission or a less nimble mission has yet to be determined. The preliminary findings from the current testing are expected to be released later this month.

Space Stories: Launch of GOES-U Satellite, Jupiter’s Surprising Atmosphere, and the Role of Black Holes in Dark Matter

—America Space: “Falcon Heavy Launches, GOES-U Heads for Geostationary Orbit“

SpaceX successfully launched its first Falcon Heavy of the year on Wednesday evening, the triple-barreled booster lifting the 11,000-pound (5,000-kilogram) Geostationary Operational Environmental Satellite (GOES-U) almost to Geostationary Earth Orbit (GEO) on behalf of the National Oceanic and Atmospheric Administration (NOAA). The Heavy—flying for the first time since November 2022 with a brand-new center core and pair of side-mounted strap-on boosters—went airborne from historic Pad 39A at Florida’s Kennedy Space Center (KSC) at 5:26 p.m. EDT, ten minutes after the opening of a two-hour “launch window”.

—European Space Agency: “Jupiter’s Upper Atmosphere Surprises Astronomers“

The Great Red Spot of Jupiter was observed by Webb’s Near-InfraRed Spectrograph (NIRSpec) in July 2022, using the instrument’s Integral Field Unit capabilities. The team’s Early Release Science observations sought to investigate if this region was in fact dull, and the region above the iconic Great Red Spot was targeted for Webb’s observations. The team was surprised to discover that the upper atmosphere hosts a variety of intricate structures, including dark arcs and bright spots, across the entire field of view. “We thought this region, perhaps naively, would be really boring,” shared team leader Henrik Melin of the University of Leicester in the United Kingdom. “It is in fact just as interesting as the northern lights, if not more so. Jupiter never ceases to surprise.”

—University of Warsaw: “Is Dark Matter Made of Black Holes?“

Gravitational wave detectors, LIGO and Virgo, have detected a population of massive black holes whose origin is one of the biggest mysteries in modern astronomy. According to one hypothesis, these objects may have formed in the very early Universe and may compose dark matter, a mysterious substance filling the Universe. A team of scientists from the OGLE (Optical Gravitational Lensing Experiment) survey from the Astronomical Observatory of the University of Warsaw have announced the results of nearly 20-year-long observations indicating that such massive black holes may comprise at most a few percent of dark matter. Another explanation, therefore, is needed for gravitational wave sources. The results of the study were published in two articles, in Nature and the Astrophysical Journal Supplement Series.

—Science.org: “A Shattered Window to the Radio Sky“

In November 2023, photographer Eric Lusito made a rare visit to the Braude Radio Astronomy Observatory near Kharkiv, Ukraine, once one of the nation’s flagship scientific facilities. Since his visit, the Kharkiv region, which was partly occupied by Russian forces in 2022 but liberated later that year, has again faced a renewed Russian assault. As of this writing, military specialists say that effort has stalled. Here is Lusito’s account of his visit.

—The Guardian: “Astronomers Detect Sudden Awakening of Black Hole 1m Times Mass of Sun“

The mysterious brightening of a galaxy far, far away has been traced to the heart of the star system and the sudden awakening of a giant black hole 1m times more massive than the sun. Decades of observations found nothing remarkable about the distant galaxy in the constellation of Virgo, but that changed at the end of 2019 when astronomers noticed a dramatic surge in its luminosity that persists to this day. Researchers now believe they are witnessing changes that have never been seen before, with the black hole at the galaxy’s core putting on an extreme cosmic light show as vast amounts of material fall into it.

—University of the Basque Country: “Establishing Age and Origin of Jupiter’s Great Red Spot“

As a popular icon among objects in the Solar System, Jupiter’s Great Red Spot (GRS) is probably the best-known atmospheric structure. Its large size (right now its diameter is that of the Earth) and the contrast of its reddish colour against the planet’s pale clouds make it an object that can be easily seen even with small telescopes…Speculation about the origin of the GRS dates back to the first telescopic observations made by the astronomer Giovanni Domenico Cassini, who in 1665 discovered a dark oval at the same latitude as the GRS and named it the ‘Permanent Spot’ (PS), since it was observed by him and other astronomers until 1713. Track of it was subsequently lost for 118 years and it was not until 1831 and later years that S. Schwabe again observed a clear structure, roughly oval in shape and at the same latitude as the GRS; that can be regarded as the first observation of the current GRS, perhaps of a nascent GRS.
