Remembering the Challenger Astronauts


When the Space Shuttle Challenger disintegrated 73 seconds after liftoff on January 28, 1986, there were seven astronauts on board whose lives were tragically cut short.


Lt. Col. Francis Richard Scobee enlisted in the U.S. Air Force after graduating from high school in 1957. He served as an engine mechanic and took college classes in his spare time, earning a degree in aerospace engineering from the University of Arizona in 1965, as well as an officer’s commission. He became a pilot the next year and served in Vietnam as a combat aviator. Scobee then became a test pilot and logged 6500 hours flying 45 different types of aircraft. After joining NASA’s astronaut program in 1978, he not only flew the space shuttle, but also instructed pilots on flying the Boeing 747 that carried shuttles to Florida.

Scobee piloted the shuttle Challenger into space on its fifth mission in April 1984; his next assignment was as commander of the Challenger mission in January 1986. Scobee told his family that his second shuttle mission might be his last. An aunt remembered, ''He said he had acquired everything he wanted in life.’’

Scobee achieved the rank of Lieutenant Colonel. He was survived by his wife and two children. His son, Major General Richard W. Scobee, is now the 10th Air Force commander of the Naval Air Station Fort Worth Joint Reserve Base.  


Captain Michael John Smith grew up near an airstrip in Morehead, North Carolina, and never wanted to do anything but fly. (Once, when he was the quarterback of a junior varsity football team, he called a timeout just so he could watch a military airplane pass overhead.) He graduated from the U.S. Naval Academy in 1967 and achieved a master’s degree in aeronautical engineering in 1968. Smith became a pilot in 1969 and served as a flight instructor until he was sent to Vietnam. There, Smith earned numerous medals and citations for two years of combat duty. He then became an instructor. Smith logged 4867 hours of flight time in 28 types of aircraft before becoming part of NASA’s astronaut program in 1980. Smith was assigned as pilot for two shuttle missions in 1986, the first scheduled for January aboard the Challenger. Smith was survived by his wife and three children.


Dr. Ronald Ervin McNair was a high achiever from an early age. He could read before starting school, and in elementary school was inspired by the Soviet Sputnik launch to pursue an education in science. In 1959, when he was 9 years old, McNair challenged the segregated public library in his hometown of Lake City, South Carolina. His brother Carl told the tale to StoryCorps.

McNair’s educational career was littered with honors, and he achieved a Ph.D. in physics from MIT in 1976. His specialties were lasers and molecular spectroscopy, knowledge he put to use at Hughes Research Laboratories. When NASA began accepting scientists and test pilots into its astronaut program in the ‘70s, McNair applied and made the 1978 class of astronaut candidates. He flew on the Challenger in 1984, spending seven days in orbit and becoming the second African American (after Guy Bluford) to fly in space. The Challenger launch in 1986 was to be his second as a mission specialist.

McNair was an accomplished saxophone player and held a 5th degree black belt in karate. He was survived by his wife and two children. In addition to several schools, streets, and parks named in his honor, the old public library building in Lake City became the Ronald E. McNair Life History Center in 2011.  


Colonel Ellison Shoji Onizuka grew up in Kealakekua, Kona, Hawaii. He earned a bachelor’s degree in aerospace engineering in June 1969 from the University of Colorado, and then a master’s degree in December that year. Onizuka immediately joined the Air Force and became an aerospace flight test engineer and then a test pilot. Selected as an astronaut candidate in 1978, Onizuka flew on Discovery—the first Department of Defense shuttle mission—in 1985, becoming the first Asian American astronaut to fly in space. In his career, Onizuka logged 1700 hours of flying time and 74 hours in space. The Challenger mission was to be his second space flight.  

Onizuka, a Lieutenant Colonel in the Air Force, was posthumously promoted to Colonel. He was survived by his wife and two daughters. Among other honors and memorials, the University of Hawaii has held the Astronaut Ellison Onizuka Science Day every year for the past 17 years to promote science education among students in grades four through 12. This year’s Science Day is Saturday, January 28.


Dr. Judith Arlene Resnika math whiz who also played classical piano, was valedictorian of the Firestone High School Class of 1966 in Akron, Ohio. After earning a perfect SAT score, Resnik went on to get a degree in electrical engineering from Carnegie-Mellon in 1970 and a Ph.D. from the University of Maryland. She helped to develop radar systems for RCA, worked as a biomedical engineer for the National Institutes of Health, and did product development for Xerox, all before being selected for the astronaut program in 1978. She was recruited by Nichelle Nichols of Star Trek fame, who was working for NASA as a recruiter at the time.  

Resnik flew on the space shuttle Discovery in August 1984 and became the second American woman in space (after Sally Ride) as well as the first Jewish American in space. The images from that mission were particularly striking because of Resnik’s long hair floating in microgravity. The Challenger mission was to be her second space flight.  

Among other memorials, the lunar crater Borman X on the far side of the moon was renamed Resnik in 1988. Resnik’s family sued the maker of the defective O-rings that caused the Challenger failure, and used the settlement funds to endow scholarships at Firestone High School and three universities.  


Gregory Bruce Jarvis was an engineer who became an Air Force captain and an astronaut specifically because of his engineering talent. He earned a bachelor’s degree in electrical engineering in 1967 and a master’s in 1969. Jarvis worked at Raytheon on the SAM-D missile project while completing his studies. He then joined the Air Force and was assigned to research on communications satellites. After an honorable discharge in 1973, Jarvis designed communications satellites for Hughes Aircraft. As an expert in satellite communications, he was selected over 600 other applicants among Hughes employees to be one of two Hughes payload specialists for NASA’s shuttle program in 1984. Jarvis was scheduled for shuttle missions and was bumped twice to make room for celebrity passengers: Utah Senator Jake Garn in March 1985 and Florida Congressman Bill Nelson on January 12, 1986. Jarvis would finally get his chance on the Challenger on January 28.

Jarvis was survived by his wife. In addition to his engineering career, he was an avid outdoorsman and played classical guitar.   


In 1984, President Ronald Reagan challenged NASA to make the shuttle’s first “citizen passenger” a teacher. The Teacher in Space Project was born, and more than 11,000 teachers applied for the position. Ultimately, Christa McAuliffe was selected.

Sharon Christa Corrigan McAuliffe held a master’s in education and a job as a social studies teacher at Concord High School in New Hampshire. She had also taught American history, English, and various other subjects at the junior high and high school levels over her 15-year teaching career. McAuliffe arranged for a year away from her job and trained with NASA in anticipation of her shuttle mission. She was supposed to deliver two live lessons broadcast to schools across the country, as well as six more lessons that would be distributed around the country after the shuttle landed.

The fact that a teacher was going to space prompted an unprecedented number of schools to watch the Challenger launch on the morning of January 28, 1986.   

McAuliffe was survived by her husband and two children. The backup teacher selected for the Teacher in Space project, Barbara Morgan, lobbied NASA to reinstate the Teacher in Space program. In 1998, she was named the first Educator Astronaut under a new program. Morgan finally got to go into space in 2007 on the shuttle Endeavour on a mission to the International Space Station.

Astronomers Discover 12 New Moons Around Jupiter

As the largest planet with the largest moon in our solar system, Jupiter is a body of record-setting proportions. The fifth planet from the Sun also boasts the most moons—and scientists just raised the count to 79.

A team of astronomers led by Scott S. Sheppard of the Carnegie Institute for Science confirmed the existence of 12 additional moons of Jupiter, 11 of which are “normal” outer moons, according to a statement from the institute. The outlier is being called an “oddball” for its bizarre orbit and diminutive size, which is about six-tenths of a mile in diameter.

The moons were first observed in the spring of 2017 while scientists looked for theoretical planet beyond Pluto, but several additional observations were needed to confirm that the celestial bodies were in fact orbiting around Jupiter. That process took a year.

“Jupiter just happened to be in the sky near the search fields where we were looking for extremely distant solar system objects, so we were serendipitously able to look for new moons around Jupiter while at the same time looking for planets at the fringes of our solar system,” Sheppard said in a statement.

Nine of the "normal" moons take about two years to orbit Jupiter in retrograde, or counter to the direction in which Jupiter spins. Scientists believe these moons are what’s left of three larger parent bodies that splintered in collisions with asteroids, comets, or other objects. The two other "normal" moons orbit in the prograde (same direction as Jupiter) and take less than a year to travel around the planet. They’re also thought to be chunks of a once-larger moon.

The oddball, on the other hand, is “more distant and more inclined” than the prograde moons. Although it orbits in prograde, it crosses the orbits of the retrograde moons, which could lead to some head-on collisions. The mass is believed to be Jupiter’s smallest moon, and scientists have suggested naming it Valetudo after the Roman goddess of health and hygiene, who happens to be the great-granddaughter of the god Jupiter.

Even if you stare closely at this seemingly grainy image, you might not be able to tell there’s anything to it besides visual noise. But it's not static—it's a sliver of the distant universe, and every little pinprick of light is a galaxy.

As Gizmodo reports, the image was produced by the European Space Agency’s Herschel Space Observatory, a space-based infrared telescope that was launched into orbit in 2009 and was decommissioned in 2013. Created by Herschel’s Spectral and Photometric Imaging Receiver (SPIRE) and Photodetector Array Camera and Spectrometer (PACS), it looks out from our galaxy toward the North Galactic Pole, a point that lies perpendicular to the Milky Way's spiral near the constellation Coma Berenices.

Each point of light comes from the heat of dust grains between different stars in a galaxy. These areas of dust gave off this radiation billions of years before reaching Herschel. Around 1000 of those pins of light belong to galaxies in the Coma Cluster (named for Coma Berenices), one of the densest clusters of galaxies in the known universe.

The longer you look at it, the smaller you’ll feel.
