New documentary reveals the triumphs and heartbreak of Sally Ride's legacy
The inspiring story of Sally Ride, the first American woman in outer space, is given its full, deserved due in a new National Geographic documentary.
And it broke my heart.
Not because of how 'Sally' depicts the incredibly capable, Stanford-educated physicist's efforts to break the highest of glass ceilings and be recognized for her abilities rather than her sex. Utilizing plentiful archival footage, contemporary commentary, recent interview observations from people who were there and some dramatized recreation, director Cristina Costantini gets some sly laughs, edged with appropriate anger, out of the sexist mindsets Ride deftly steered her career through in the 1970s and '80s.
What makes 'Sally' so sad was the astronaut's decision to keep her sexuality secret — as her public image soared to heights few women had ever known — until her death from pancreatic cancer in 2012. This aspect of her life grows especially poignant in the film due to the participation of Tam O'Shaughnessy. A tennis buddy Ride met when they were tweens (both Southern California girls were mentored by Billie Jean King), O'Shaughnessy later became her life partner of 27 years.
An erudite biology professor, O'Shaughnessy provides much of the film's insight into Ride's personal life during extensive interview stretches and, presumably, via additional input behind the scenes (she has an executive producer credit). Subjective as some of this may be, it's powerful emotional stuff that often reveals more about O'Shaughnessy's own feelings than about Ride herself, who remained enigmatic — even to the love of her life. Fellow astronaut Steven Hawley, who was married to Ride for five years, still seems baffled by what was really going on with her.
But like her subject, Costantini maintains a certain rigor in the sentiment department. She doesn't come close to suggesting that Ride was riddled with personal anxieties or fears of being outed. On the other hand, the NASA legend is neither presented as emotionless, calculating nor furtive, but rather as a focused professional who could separate the joy in her achievements from the cacophony of everything else.
One brief clip of her mother Carol reinforces the telling intel that Ride was not raised in a demonstrative home.
'If I knew how I felt about feelings, I would probably not tell you,' an immovable Carol says to the camera.
Yet Ride's determination, boldness and courage come across palpable. This is brought home when, following her own groundbreaking missions, Ride became the only Space Shuttle astronaut on the committee investigating the Challenger disaster. As the movie frames it, she essentially sacrificed her own future at NASA to expose the cause of the post-launch explosion, and the systemic incompetence that led to it.
Costantini ('Science Fair,' 'Mucho Mucho Amor') said she has been a Sally Ride fan since third grade, when she painted a mural of her hero on a school wall. With 'Sally,' she presents a portrait of a pure scientist cognizant of the example she was setting for girls and women of all generations to come. The film is indelibly triumphant in that way; its sadness is generated partly by Ride's apparent inability to fully master the science of love, and certainly by the restrictions a homophobic culture placed on her at the time.
There's a clip near the end of Barack Obama presenting Ride's posthumous Presidential Medal of Freedom to O'Shaughnessy. It's a beautiful moment of acknowledgement too-long delayed — one that would never happen today. Perhaps the most heart-rending lesson 'Sally' imparts is that that final frontier keeps getting moved out of reach.

A hunt for ghostly particles found strange signals coming from Antarctic ice. Scientists are still trying to explain them
Scientists are trying to solve a decade-long mystery by determining the identity of anomalous signals detected from below ice in Antarctica. The strange radio waves emerged during a search for another unusual phenomenon: high-energy cosmic particles known as neutrinos. Arriving at Earth from the far reaches of the cosmos, neutrinos are often called 'ghostly' because they are extremely volatile, or vaporous, and can go through any kind of matter without changing. Over the past decade, researchers have conducted multiple experiments using vast expanses of water and ice that are designed to search for neutrinos, which could shed light on mysterious cosmic rays, the most highly energetic particles in the universe. One of these projects was NASA's Antarctic Impulsive Transient Antenna, or ANITA, experiment, which flew balloons carrying instruments above Antarctica between 2006 and 2016. It was during this hunt that ANITA picked up anomalous radio waves that didn't seem to be neutrinos. The signals came from below the horizon, suggesting they had passed through thousands of miles of rock before reaching the detector. But the radio waves should have been absorbed by the rock. The ANITA team believed these anomalous signals could not be explained by the current understanding of particle physics. Follow-up observations and analyses with other instruments, including one recently conducted by the Pierre Auger Observatory in Argentina, have not been able to find the same signals. The results of the Pierre Auger Collaboration were published in the journal Physical Review Letters in March. The origin of the anomalous signals remains unclear, said study coauthor Stephanie Wissel, associate professor of physics, astronomy and astrophysics at the Pennsylvania State University. 'Our new study indicates that such (signals) have not been seen by an experiment … like the Pierre Auger Observatory,' Wissel said. 'So, it does not indicate that there is new physics, but rather more information to add to the story.' Larger, more sensitive detectors may be able to solve the mystery, or ultimately prove whether the anomalous signals were a fluke, while continuing the search for enigmatic neutrinos and their sources, scientists say. Detecting neutrinos on Earth allows researchers to trace them back to their sources, which scientists believe are primarily cosmic rays that strike our planet's atmosphere. The most highly energetic particles in the universe, cosmic rays are made up mostly of protons or atomic nuclei, and they are unleashed across the universe because whatever produces them is such a powerful particle accelerator that it dwarfs the capabilities of the Large Hadron Collider. Neutrinos could help astronomers better understand cosmic rays and what launches them across the cosmos. But neutrinos are difficult to find because they have almost no mass and can pass through the most extreme environments, like stars and entire galaxies, unchanged. They do, however, interact with water and ice. ANITA was designed to search for the highest energy neutrinos in the universe, at higher energies than have yet been detected, said Justin Vandenbroucke, an associate professor of physics at the University of Wisconsin, Madison. The experiment's radio antennae search for a short pulse of radio waves produced when a neutrino collides with an atom in the Antarctic ice, leading to a shower of lower-energy particles, he said. During its flights, ANITA found high-energy fountains of particles coming from the ice, a kind of upside-down shower of cosmic rays. The detector is also sensitive to ultrahigh energy cosmic rays that rain down on Earth and create a radio burst that acts like a flashlight beam of radio waves. When ANITA watches a cosmic ray, the flashlight beam is really a burst of radio waves one-billionth of a second long that can be mapped like a wave to show how it reflects off the ice. Twice in their data from ANITA flights, the experiment's original team spotted signals coming up through the ice at a much sharper angle than ever predicted by any models, making it impossible to trace the signals to their original sources. 'The radio waves that we detected nearly a decade ago were at really steep angles, like 30 degrees below the surface of the ice,' Wissel said. Neutrinos can travel through a lot of matter, but not all the way through the Earth, Vandenbroucke said. 'They are expected to arrive from slightly below the horizon, where there is not much Earth for them to be absorbed,' he wrote in an email. 'The ANITA anomalous events are intriguing because they appear to come from well below the horizon, so the neutrinos would have to travel through much of the Earth. This is not possible according to the Standard Model of particle physics.' The Pierre Auger Collaboration, which includes hundreds of scientists around the world, analyzed more than a decade's worth of data to try to understand the anomalous signals detected by ANITA. The team also used their observatory to try to find the same signals. The Auger Observatory is a hybrid detector that uses two methods to find and study cosmic rays. One method relies on finding high-energy particles as they interact with water in tanks on Earth's surface, and the other tracks potential interactions with ultraviolet light high in our planet's atmosphere. 'The Auger Observatory uses a very different technique to observe ultrahigh energy cosmic ray air showers, using the secondary glow of charged particles as they traverse the atmosphere to determine the direction of the cosmic ray that initiated it,' said Peter Gorham, a professor of physics at the University of Hawaii at Mānoa. 'By using computer simulations of what such a shower of particles would look like if it had behaved like the ANITA anomalous events, they are able to generate a kind of template for similar events and then search their data to see if anything like that appears.' Gorham, who was not involved with the new research, designed the ANITA experiment and has conducted other research to understand more about the anomalous signals. While the Auger Observatory was designed to measure downward-going particle showers produced in the atmosphere by ultrahigh-energy cosmic rays, the team redesigned their data analysis to search for upward-going air showers, Vandenbroucke said. Vandenbroucke did not work on the new study, but he peer-reviewed it prior to publication. 'Auger has an enormous collecting area for such events, larger than ANITA,' he said. 'If the ANITA anomalous events are produced by any particle traveling through the Earth and then producing upward-going showers, then Auger should have detected many of them, and it did not.' A separate follow-up study using the IceCube Experiment, which has sensors embedded deep in the Antarctic ice, also searched for the anomalous signals. 'Because IceCube is very sensitive, if the ANITA anomalous events were neutrinos then we would have detected them,' wrote Vandenbroucke, who served as colead of the IceCube Neutrino Sources working group between 2019 and 2022. 'It's an interesting problem because we still don't actually have an explanation for what those anomalies are, but what we do know is that they're most likely not representing neutrinos,' Wissel said. Oddly enough, a different kind of neutrino, called a tau neutrino, is one hypothesis that some scientists have put forth as the cause of the anomalous signals. Tau neutrinos can regenerate. When they decay at high energies, they produce another tau neutrino, as well as a particle called a tau lepton — similar to an electron, but much heavier. But what makes the tau neutrino scenario very unlikely is the steepness of the angle connected to the signal, Wissel said. 'You expect all these tau neutrinos to be very, very close to the horizon, like maybe one to five degrees below the horizon,' Wissel said. 'These are 30 degrees below the horizon. There's just too much material. They really would actually lose quite a bit of energy and not be detectable.' At the end of the day, Gorham and the other scientists have no idea what the origin of the anomalous ANITA events are. So far, no interpretations match up with the signals, which is what keeps drawing scientists back to try to solve the mystery. The answer may be in sight, however. Wissel is also working on a new detector, the Payload for Ultra-High Energy Observations or PUEO, that will fly over Antarctica for a month beginning in December. Larger and 10 times more sensitive than ANITA, PUEO could reveal more information on what is causing the anomalous signals detected by ANITA, Wissel said. 'Right now, it's one of these long-standing mysteries,' Wissel said. 'I'm excited that when we fly PUEO, we'll have better sensitivity. In principle, we should be able to better understand these anomalies which will go a long way to understanding our backgrounds and ultimately detecting neutrinos in the future.' Gorham said that PUEO, an acronym that references the Hawaiian owl, should have the sensitivity to capture many anomalous signals and help scientists find an answer. 'Sometimes you just have to go back to the drawing board and really figure out what these things are,' Wissel said. 'The most likely scenario is that it's some mundane physics that can be explained, but we're sort of knocking on all the doors to try to figure out what those are.'

A ‘big, beautiful deal', America's aerospace ‘revolution' and other commentary
Iran-Israel war: A 'Big, Beautiful Deal' 'Proponents of an American strike believe that we have no realistic choice other than to help Israel do as thorough a job as possible in setting back Iran's nuclear ambitions,' contends The New York Times' Bret Stephens. True, after Trump drops bunker busters on the Fordow nuclear site, the question is 'what comes afterward.' But the president can follow that up with 'a diplomatic bunker buster on Tehran': lifting economic sanctions and forcing the Israelis to stop the bombings. 'Nobody, perhaps even President Trump himself, knows for sure whether the United States will wind up joining Israel in launching military strikes on Iran.' But 'there's a big, beautiful deal to be struck here. For all sides.' Tech watch: America's Aerospace 'Revolution' Advertisement 'From LAX to coastal San Diego,' dozens of new firms are 'embracing the country's emerging 'hard tech' revolution,' cheers Joel Kotkin at UnHerd. Including around 40 spinoffs of SpaceX, they make everything — largely for aerospace — 'from drones to engines, drilling systems to satellites.' Together, they can 'restore' America's 'blue-collar prosperity.' Given the 'military implications' of these products, these firms embrace a 'Right-wing patriotism' and so threaten to change corporate culture. Yet 'the biggest pool of money' is not from the Defense Department but the 'burgeoning space industry.' And the 'technology looks set to dominate our century. For if those robots and satellites are all impressive enough in theory, they could yet be used as a geopolitical battering ram' — with US innovators as 'riposte to Chinese central planning.' Libertarian: Czechs to the Rescue in Ukraine 'Through online fundraisers organized by community platforms like 'Gift for Putin,' 'Team for Ukraine,' or 'Just Retribution,' Czech citizens have donated millions of dollars toward' arms for Ukraine, marvels Miroslav Hanušniak at Reason. These include much-needed rifle magazines, howitzer shells, a Black Hawk helicopter and 'more than $11.5 million toward the direct purchase of First Person View drones.' Czechs 'show no signs of slowing down. New initiatives continue to emerge, finding creative ways to support the needs of the Armed Forces of Ukraine.' In neighboring Slovakia, citizens defied their Russian-leaning 'government's stance and joined the fundraising efforts, contributing millions.' It's a reminder that 'real power and meaningful change do not always come from parliaments.' Advertisement Defense beat: Space — Aukus' Final Frontier 'It's time for Aukus,' the Australia, US and UK alliance, 'to grow,' argues Scott Morrison at The Wall Street Journal, and Trump 'is the right person for the job.' Aukus 'enables Australia's acquisition of its first nuclear-powered sub fleet' and 'facilitates cooperation on advanced military capabilities,' notes the former Australian prime minister. But 'if our nations are serious about deterrence, then we must prepare for new theaters of geopolitical competition' — particularly space. Aukus should be expanded to consolidate 'cooperation across launch systems, satellite architecture, cybersecurity, data integration and industrial innovation.' It must ensure that space 'is secured by free nations, not our enemies. American and Australia have stood shoulder to shoulder on land, at sea and in the skies. Now we must do the same in orbit.' Hispanic pastor: Riots Hurt Protesters' Cause Advertisement 'Once more, the streets of Los Angeles are filled with chaos' because of 'modern-day anarchists,' blasts Samuel Rodriguez for The Hill. Blame it on Team Biden's border 'failure,' which 'permitted millions to enter our country without any real verification process.' Now 'the majority of these riots are being led, organized, and amplified by Antifa factions and ultra-left progressive groups whose mission is not reform but total revolution.' These thugs are 'protesting the deportation of individuals who are violent criminals, rapists, murderers, or pedophiles.' 'There is a legitimate space for expressing concern over the deportation of longstanding immigrants who have lived here peacefully,' but 'these riots hurt and did not help their cause. This lawlessness is antithetical to everything the immigrant rights movement hopes to achieve.' — Compiled by The Post Editorial Board
