Forty Years Ago: Apollo 13

The number 13 had a bad reputation long before 1970, but it only got worse on April 13 of that year. Just eight months earlier, Neil Armstrong set foot on the moon. Apollo 12 had a successful mission to the moon in November. But Apollo 13 had that number. Lift off two days earlier was at 1:13 PM, or 13:13 in military time. Apollo 13 commander Jim Lovell noticed the coincidence of the time, but he is not a superstitious man. Besides, lift-off was on April 11th. He, Jack Swigert, and Fred Haise were on their way to the moon to explore the Fra Mauro highlands and bring back moon samples.

On the 13th, two days into the flight, there was a loud bang. Lovell and Swigert looked at Haise, who had startled the crew members before by actuating a lunar module relief valve. But this was no prank. A liquid oxygen tank had exploded, which blew out the side of the service module. Power went down. Oxygen leaked out.

Swigert and Lovell radioed Mission Control with those understated words, "Houston, we've had a problem." The crew at Mission Control who had complained of boredom over the previous two days would never do so again. The original mission was aborted; the new mission was to get the three crewmen back to earth alive. Flight director Gene Kranz and his team hunkered down to figure out how to stretch the spaceship's available resources.

To conserve energy, all but essential systems were shut down. The astronauts moved into the lunar module, which had enough resources for two days for two men. Now, those resources would have to last four days for three men. There was backup oxygen on board, but power and water had to be conserved. And carbon dioxide buildup would be a problem.

Mission Control worked on the filter problem. The canisters of lithium hydroxide used to filter carbon dioxide in the lunar module were a different size from the available canisters in the command module. On directions from Houston, the crew rigged up a system using duct tape and hosing, to adapt the command module's canisters for lunar module use. The contraption they built was called the "mailbox".

Also to conserve energy, on board television cameras were turned off, and NASA used miniatures and animations to keep the public informed of Apollo 13's progress.

With critically low resources, there was no way the crew could land on the moon, but they continued on the trajectory to the moon in order to pass around it and gain momentum from the moon's gravity to coast back to earth. This picture was taken from Apollo 13's lunar flyby.

On approach to earth, the crew jettisoned the damaged service module, then moved into the command module and jettisoned their "lifeboat", the lunar module. They splashed down in the Pacific on April 17th, four days after the tank explosion.

An investigation into what went wrong with Apollo 13 found that a heating wire inside the liquid oxygen tank had lost its insulation, which led to the explosion. The cause was a combination of mistakes in design, testing, and implementation. The report is available online. The entire Apollo 13 operations team was awarded the Presidential Medal of Freedom as a group.

Mission number 13 may have been unlucky to have experienced the explosion, but an entire series of lucky breaks and intelligent decisions contributed to the crew's safe return. Lovell wrote a book about the mission, Lost Moon in 1994.  It became a best seller. Ron Howard made the book into the 1995 movie Apollo 13.

Tom Hanks was nervous about his role as commander Jim Lovell, because an actor  rarely gets the chance to play one of his childhood heroes. But the movie introduced a new generation to the real-life suspense of the Apollo 13 mission.

Jim Lovell and Fred Haise got together yesterday with Gene Krantz and other members of the Apollo 13 team at the Adler Planetarium in Chicago to mark the 40th anniversary of the flight. Jack Swigert died in 1982. Jim Lovell, now 82, owns a restaurant in Lake Forest, Illinois. Fred Haise, now 76, is building a science museum in Mississippi.

4 Suspect Historical Theories for Predicting Criminality

When was the last time you looked a stranger in the face and made a snap judgment about how they behave? If you've graduated kindergarten, you know you're not supposed to. But for centuries, scientists and philosophers believed that physical traits corresponded to personality. Even Aristotle thought there was a connection between the book and its cover.

Today, physiognomy—as the study of facial features linked to personality became known—is considered a pseudoscience, but it was the first application of any science at all to criminology. Some argue that it helped pave the way for the development of forensics and tools like psychological profiling; others point out that attempts to link biology to criminal behavior are often deeply problematic, and have been used to justify discrimination against various ethnic and religious groups.

Controversial though they may be, theories linking biology to criminal behavior have not gone away. From skull shape to body types, here are some of the ways we've tried to use what's on the surface to unearth the monsters underneath.

1. PHRENOLOGY

As a young man in late 18th-century Vienna, physician Franz Josef Gall wondered why his classmates were so good at memorization while he struggled. And why did he surpass them in other areas? After noticing that those who were particularly skilled at memorization had prominent eyes, he spent years searching for a biological explanation for differences in mental characteristics. Eventually, he landed on a theory that aimed to explain all human behavior.

Gall based his theory, soon to be known as phrenology, on the notion that the brain was composed of 27 separate “faculties,” or organs, each responsible for a behavioral trait—benevolence, covetousness, arrogance, and wit, just to name a few. He believed that the size of an organ was correlated to its power and that the skull took its shape from the brain. As such, by examining the shape of the skull one could determine personality. Eventually, Gall's followers introduced the idea that people were born with their faculties in balance and were essentially good, but under- or over- development, diseases of, or damage to any of these faculties could cause an imbalance that would lead to a particular behavior.

Phrenology soon took off in Europe and then in North America. It wasn't long until Gall's acolytes were applying his principles to the study of criminality, examining the skulls of criminals for clues about their personality and publishing books and treatises that showed others how to do the same. For phrenologists, crime was a result of an overgrowth or other anomaly in a particular faculty—say, destructiveness.

By attributing behavior to a brain defect, phrenology broke with existing notions of deviant behavior. Pre-Enlightenment theory had held that such behavior was the result of “evil” or supernatural forces. During the Enlightenment, free will reigned supreme, and criminality was seen as an exercise of that will, the only deterrent for which was severe punishment. Phrenology removed free will from the equation. While those with “normal” faculties could commit crimes based on free will and should be punished accordingly, the habitually criminal were not necessarily responsible for their actions—they behaved the way they did because of mental disorder, one which could be addressed and treated. It's no coincidence that phrenologists were among the most vocal opponents of capital and corporal punishment and major proponents of rehabilitation in the middle of the 19th century.

Phrenology declined in popularity in the second half of the 19th century, although it persisted into the 20th century in some areas. For a brief moment, it was the first and most comprehensive scientific approach we had to criminology.

2. DEGENERATION

Sometimes called the “father of criminology,” Italian physician Cesare Lombroso spent much of his career examining the bodies (both dead and alive) of convicted criminals and the mentally ill. The army doctor and professor of psychiatry was struck by both Darwin's theories and the work of Italian evolutionists during the 1860s, and evolution greatly influenced his later work.

Like Gall, Lombroso experienced a “eureka” moment while making a minute examination of a human head—only in his case, it was the skull of the recently deceased thief and arsonist Giuseppe Villella. Villella had a small indentation at the back of his skull; unusual for a human, but common in some primates. Lombroso noticed the trait in a few other crooks, and theorized that criminals were in fact some evolutionary throwback to primitive humans. He began to argue that deviance was inherited in many of these “born delinquents,” and they could be differentiated from the masses by physical characteristics that he claimed resembled our primate ancestors: large jaws, jug ears, high cheekbones, bloodshot eyes, to name a few attributes. Behavioral traits like idleness and non-biological features like tattoos could also be a sign.

Lombroso ran experiments on prisoners, the insane, and even low-lifes he wrangled from Italian alleyways. He took measurements of their bodies and features and tested their blood pressure, pain resistance, and reaction to other stimuli. Over the years, he established a set of features associated with different types of crime. His theory, known as degeneration, laid the foundation for a systematic approach to crime and even punishment. Like the phrenologists, Lombroso and his acolytes argued against capital punishment for those whose degeneration was not particularly advanced but triggered by an environmental factor—they were to be treated rather than locked up.

While wildly popular during his lifetime (he even argued the merits of his theory with Russian novelist Leo Tolstoy while visiting the writer's home), Lombroso's ideas faded from prominence as sociological theories of crime became more popular at the turn of the 20th century. Besides his emphasis on a scientific approach to criminology, his legacy consists of a museum in Turin stocked with the skulls and other ephemera he collected throughout his career ... along with the good doctor's own head, preserved in a jar.

3. SOMATOTYPES

Body type is blamed for a lot these days—a propensity for obesity, jeans that don't fit quite right. But in the early 20th century, an American psychologist named William Sheldon looked a little deeper.

Sheldon examined some 4000 photographs of college students and distilled their bodies into three categories, or somatotypes: endomorphs, mesomorphs, and ectomorphs. Endomorphs were soft, round, and put on fat easily; they were also amiable, relaxed, and extroverted. Mesomorphs were hard, muscular, and broad-chested; they were also assertive, aggressive, and insensitive. Finally, ectomorphs were long, narrow, and fragile-looking; they were also more introverted and anxious. Bodies fell into a spectrum defined by the degree to which they exhibited each of these three traits.

In a study of 200 delinquent youths, Sheldon concluded that mesomorphs had the greatest predisposition for impulsive (and thus perhaps criminal) behavior. While his work was criticized for its methodology, Sheldon did attract more than a few students, some of whom modified his theory to include social pressures; for example, it was possible that society treated people with certain physical characteristics a certain way, thereby encouraging delinquency.

4. XYY SYNDROME

In 1961, a 44-year-old man underwent genetic testing after discovering his child had Down syndrome. The test results surprised his doctor—the man had an extra Y chromosome. Over the following decades, further testing revealed that XYY syndrome, as it became known, was rather common, appearing in men at a rate of 1 in 1000.

In 1965, when a study from a Scottish institution for people with dangerous, violent, or criminal propensities reported a high frequency of XYY syndrome among its population, scientists and the media alike began to wonder if that extra chromosome somehow caused violence and aggression in men. XYY was used as a defense in the trial of a French murderer, and has been brought up in regard to the case of Richard Speck, the student nurse killer of Chicago, though he turned out not to have the extra Y. Books and TV shows featured XYY killers even into the 1990s.

But what does the science say? While men with XYY syndrome tend to be taller, more active, and have a greater chance of having learning or behavioral problems, there's been no evidence showing a decrease in intelligence or a higher propensity for violence or aggression. In fact, most XYY men are unaware of their genetic quirk and blend perfectly well into the rest of the population. While two Dutch studies did show an increase in criminal convictions among XYY men, researchers have posited that this could be explained away based on socioeconomic variables that have also been linked to the chromosome aberrations.

For now, the XYY theory remains just a theory—as well as a convenient plot device.

Astronauts on the ISS to Teach Christa McAuliffe's Lost Science Lessons

Christa McAuliffe was set to become the first private citizen to travel to space when she boarded the Challenger space shuttle on January 28, 1986. That dream was cut tragically short when the shuttle exploded 73 seconds after liftoff, killing all seven passengers onboard. Now, 32 years later, part of McAuliffe's mission will finally be realized. As SFGate reports, two NASA astronauts are teaching her lost science lessons in space.

Before she was selected to join the Challenger crew, McAuliffe taught social studies at a Concord, New Hampshire high school. Her astronaut status was awarded as part of NASA's Teacher in Space Project, a program designed to inspire student interest in math, science, and space exploration. McAuliffe was chosen out of an applicant pool of more than 11,000.

Once in orbit, McAuliffe had planned to conduct live and taped lessons in microgravity for her students and the world to see. Though that never happened, she left behind enough notes and practice videos for astronauts to carry through with her legacy 32 years later. On Friday, January 19, astronaut Joe Acaba announced that he and his colleague Ricky Arnold will be sharing her lessons from the International Space Station over the upcoming months. The news was shared during a TV linkup with students at Framingham State University where McAuliffe studied.

McAuliffe's lost lesson plan includes experiments with Newton's laws of motion, bubbles, chromatography, and liquids in space, all of which will be recorded by Acaba and Arnold and shared online through the Challenger Center, a nonprofit promoting space science education.

It will be the first time students will get to see the lessons performed in space, but it won't be the only footage of the lessons available on the internet. Before the doomed Challenger flight, McAuliffe was able to practice her experiments in NASA's famous Vomit Comet. You can watch one of her demonstrations below.
