In October 1604, a new star appeared in the sky, puzzling astronomers of the day. First observed on Oct. 9, German astronomer Johannes Kepler (1571-1630) began his observations on Oct. 17 and tracked the new star for over a year. During that time, it brightened to magnitude -2.5, outshining Jupiter, and for several weeks remained visible in the daytime. Publication of his detailed observations in 1606 led astronomers to call the star Kepler’s Supernova, today formally designated as supernova SN 1604. Astronomers of the day did not know what caused the star’s sudden appearance and eventual disappearance, but the phenomenon helped shape European cosmology toward the heliocentric model proposed by Polish astronomer Nicolaus Copernicus half a century earlier. Today, astronomers designate SN 1604 as a Type Ia supernova, resulting from the explosion of a white dwarf star, and use ground-based and space-based telescopes to study its remnants.

Right: Closeup of Kepler’s illustration of the location of the new star, designated N, in the constellation Ophiuchus near the right foot of the serpent-bearer.
Italian astronomer Lodovico delle Colombo first observed the supernova in the constellation Ophiuchus on Oct. 9. Kepler, then working in Prague, heard rumors of the new star but did not observe it until Oct. 17. He continued to monitor the star for over a year, inspired by the earlier work of Danish astronomer Tycho Brahe’s observations of a similar phenomenon, the 1572 supernova. The new star quickly brightened to magnitude -2.5, outshining Jupiter, and for three weeks could be seen in the daytime before finally fading into obscurity in March 1606. Kepler could only make naked eye observations, since Italian astronomer Galileo Galilei didn’t turn his newly invented telescope to the skies for another four years after SN 1604 faded from view.
Later in 1606, Kepler summarized his observations in his book De Stella nova in pede Serpentarii (On the New Star in Ophiuchus’ Foot), published in Prague. SN 1604 is believed to be about 20,000 light years away, near the edge of a dark nebula complex. Kepler and his contemporaries observed not only the last known supernova to occur in the Milky Way Galaxy but also the last supernova visible to the naked eye until 1987. That one, Supernova 1987A, appeared in the Large Magellanic Cloud, a small satellite galaxy of the Milky Way.
A Type Ia supernova results from a white dwarf drawing in material from a nearby red giant star, the additional mass leading to a runaway thermonuclear explosion.
Astronomers today understand that what Kepler and others believed as the birth of a new star actually represented the violent death of a star. Astronomers today classify supernovas according to their characteristics, and SN 1604 belongs to the group known as Type Ia supernovas, typically found in binary star systems composed of a white dwarf and a red giant. The gravitation force of the white dwarf draws in material from its larger less dense companion until it reaches a critical mass, around 1.4 times the mass of our Sun. At that point, a runaway thermonuclear chain reaction begins, causing a release of tremendous amounts of energy, including light, that we see as a sudden brightening of an otherwise dim star.

Supernova explosions leave remnants behind and those of SN 1604 remain visible today. Ground-based and space-based instruments using different parts of the electromagnetic spectrum study these remnants to gain a better understanding of their origins. The remnants of SN 1604 emit energy most strongly in the radio and X-ray parts of the electromagnetic spectrum. In recent years, astronomers have used Type Ia supernovas to determine the rate of expansion of the universe. Because Type Ia supernovas all occur in stars of about 1.4 solar masses, they give out about the same amount of light. This makes them useful as distance indicators – if one Type Ia supernova is dimmer than another one, it is further away by an amount that astronomers can calculate. Based on this information, astronomers believe that the expansion of the universe is accelerating, possibly caused by the presence of a mysterious substance called dark energy.

The 13th flight of the space shuttle program and the sixth of Challenger, STS-41G holds many distinctions. As the first mission focused almost entirely on studying the Earth, it deployed a satellite, employed multiple instruments, cameras, and crew observations to accomplish those goals. The STS-41G crew set several firsts, most notably as the first seven-member space crew. Other milestones included the first astronaut to make a fourth shuttle flight, the first and only astronaut to fly on Challenger three times and on back-to-back missions on any orbiter, the first crew to include two women, the first American woman to make two spaceflights, the first American woman to conduct a spacewalk, and the first Canadian and the first Australian-born American to make spaceflights.

In November 1983, NASA named the five-person crew for STS-41G, formerly known as STS-17, then planned as a 10-day mission aboard Columbia in August 1984. When assigned to STS-41G, Commander Robert L. Crippen had already completed two missions, STS-1 and STS-7, and planned to command STS-41C in April 1984. On STS-41G, he made a record-setting fourth flight on a space shuttle, and as it turned out the first and only person to fly aboard Challenger three times, including back-to-back missions. Pilot Jon A. McBride, and mission specialists Kathryn D. Sullivan from the Class of 1978 and, David C. Leestma from the Class of 1980, made their first flights into space. Mission specialist Sally K. Ride made her second flight, and holds the distinction as the first American woman to return to space, having flown with Crippen on STS-7. The flight marked the first time that two women, Ride and Sullivan, flew in space at the same time. In addition, Sullivan holds the honor as the first American woman to conduct a spacewalk and made her second flight and holds the distinction as the first American woman to return to space, having flown with Crippen on STS-7. The flight marked the first time that two women, Ride and Sullivan, flew in space at the same time. In addition, Sullivan holds the honor as the first American woman to conduct a spacewalk, and Leestma as the first of the astronaut Class of 1980 to make a spaceflight.
Columbia’s refurbishment following STS-9 ran behind schedule and could not meet the August launch date, so NASA switched STS-41G to the roomier and lighter weight Challenger. This enabled adding crew members to the flight. In February 1984, NASA and the Canadian government agreed to fly a Canadian on an upcoming mission in recognition for that country’s major contribution to the shuttle program, the Remote Manipulator System (RMS), or robotic arm. In March, Canada named Marc Garneau as the prime crewmember with Robert B. Thirsk as his backup. NASA first assigned Garneau to STS-51A, but with the switch to Challenger transferred him to the STS-41G crew. On June 1, NASA added Australian-born and naturalized U.S. citizen Paul D. Scully-Power, an oceanographer with the Naval Research Laboratory who had trained shuttle crews in recognizing ocean phenomena from space, to the mission rounding out the seven-person crew, the largest flown to that time. Scully-Power has the distinction as the first person to launch into space sporting a beard.

Middle: The Earth Resources Budget Satellite during processing at KSC for STS-41G. Right: Technicians at KSC process the Shuttle Imaging Radar-B for the STS-41G mission.
The STS 41G mission carried a suite of instruments to study the Earth. The Earth Radiation Budget Satellite (ERBS), managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, contained three instruments, including the Stratospheric Aerosol and Gas Experiment-2 (SAGE-2), to measure solar and thermal radiation of the Earth to better understand global climate changes. NASA’s Office of Space and Terrestrial Applications sponsored a cargo bay-mounted payload (OSTA-3) consisting of four instruments. The Shuttle Imaging Radar-B (SIR-B), managed by NASA’s Jet Propulsion Laboratory in Pasadena, California, and an updated version of SIR-A flown on STS-2, used synthetic aperture radar to support investigations in diverse disciplines such as archaeology, geology, cartography, oceanography, and vegetation studies. Making its first flight into space, the 900-pound Large Format Camera (LFC) took images of selected Earth targets on 9-by-18-inch film with 70-foot resolution. The Measurement of Air Pollution from Satellites (MAPS) experiment provided information about industrial pollutants in the atmosphere. The Feature Identification and Location Experiment (FILE) contained two television cameras to improve the efficiency of future remote sensing equipment. In an orbit inclined 57 degrees to the Equator, the instruments aboard Challenger could observe more than 75% of the Earth’s surface.
The Orbital Refueling System (ORS), managed by NASA’s Johnson Space Center in Houston, while not directly an Earth observation payload, assessed the feasibility of on-orbit refueling of the Landsat-4 remote sensing satellite, then under consideration as a mission in 1987, as well as Department of Defense satellites not designed for on-orbit refueling. In the demonstration, the astronauts remotely controlled the transfer of hydrazine, a highly toxic fuel, between two tanks mounted in the payload bay. During a spacewalk, two crew members simulated connecting the refueling system to a satellite and later tested the connection with another remotely controlled fuel transfer. Rounding out the payload activities, the large format IMAX camera made its third trip into space, with footage used to produce the film “The Dream is Alive.”

Following the STS-41C mission, Challenger returned to KSC from Edwards Air Force Base in California on April 18. Workers in KSC’s Orbiter Processing Facility refurbished the orbiter and changed out its payloads. Rollover to the Vehicle Assembly Building (VAB) took place on Sept. 8 and after workers stacked Challenger with its External Tank and Solid Rocket Boosters, they rolled it out of the VAB to Launch Pad 39A on Sept. 13. Just two days later, engineers completed the Terminal Countdown Demonstration Test, a final dress rehearsal before the actual countdown and launch, with the astronaut crew participating as on launch day. They returned to KSC on Oct. 2 to prepare for the launch three days later.

Space shuttle Challenger roared off Launch Pad 39A at 7:03 a.m. EDT, 15 minutes before sunrise, on Oct. 5, 1984, to begin the STS-41G mission. The launch took place just 30 days after the landing of the previous mission, STS-41D. That record-breaking turnaround time between shuttle flights did not last long, as the launch of Discovery on STS-51A just 26 days after Challenger’s landing set a new record on Nov. 8.
Eight and a half minutes after liftoff, Challenger and its seven-member crew reached space and shortly thereafter settled into a 218-mile-high orbit, ideal for the deployment of the 5,087-pound ERBS. The crew noted that a 40-inch strip of Flexible Reusable Surface Insulation (FRSI) had come loose from Challenger’s right-hand Orbiter Maneuvering System (OMS) pod, presumably lost during launch. Mission Control determined that this would not have any impact during reentry. Ride grappled the ERBS with the shuttle’s RMS but when she commanded the satellite to deploy its solar arrays, nothing happened. Mission Control surmised that the hinges on the arrays had frozen, and after Ride oriented the satellite into direct sunlight and shook it slightly on the end of the arm, the panels deployed. She released ERBS about two and a half hours late and McBride fired Challenger’s steering jets to pull away from the satellite. Its onboard thrusters boosted ERBS into its operational 380-mile-high orbit. With an expected two-year lifetime, it actually operated until October 14, 2005, returning data about how the Earth’s atmosphere absorbs and re-radiates the Sun’s energy, contributing significant information about global climate change.

Near the end of their first day in space, the astronauts opened the panels of the SIR-B antenna and activated it, also deploying the Ku-band antenna that Challenger used to communicate with the Tracking and Data Relay System (TDRS) satellite. The SIR-B required a working Ku-band antenna to downlink the large volume of data it collected, although it could store a limited amount on onboard tape recorders. But after about two minutes, the data stream to the ground stopped. One of the two motors that steered the Ku antenna failed and it could no longer point to the TDRS satellite. Mission Control devised a workaround to fix the Ku antenna in one position and steer the orbiter to point it to the TDRS satellite and downlink the stored data to the ground. Challenger carried sufficient fuel for all the maneuvering, but the extra time for the attitude changes resulted in achieving only about 40% of the planned data takes. The discovery of the 3,000-year-old lost city of Udar in the desert of Oman resulted from SIR-B data, one of many interesting findings from the mission.

During the second mission day, the astronauts lowered Challenger’s orbit to an intermediate altitude of 151 miles. Flight rules required that the SIR-B antenna be stowed for such maneuvers but the latches to clamp the antenna closed failed to activate. Ride used the RMS to nudge the antenna panel closed. From the orbiter’s flight deck, Leestma successfully completed the first ORS remote-controlled hydrazine fuel transfer. Garneau began working on his ten CANEX investigations related to medical, atmospheric, climatic, materials and robotic sciences while Scully-Power initiated his oceanographic observations. Despite greater than expected global cloud cover, he successfully photographed spiral eddies in the world’s oceans, particularly notable in the eastern Mediterranean Sea.

The third day saw the crew lower Challenger’s orbit to 140 miles, the optimal altitude for SIR-B and the other Earth observing instruments. For the next few days, all the experiments continued recording their data, including Garneau’s CANEX and Scully-Power’s oceanography studies. Leestma completed several scheduled ORS fuel transfers prior to the spacewalk. Preparations for that activity began on flight day 6 with the crew lowering the cabin pressure inside Challenger from the normal sea level 14.7 pounds per square inch (psi) to 10.2 psi. The lower pressure prevented the buildup of nitrogen bubbles in the bloodstreams of the two spacewalkers, Leestma and Sullivan, that could result in the development of the bends. The two verified the readiness of their spacesuits.

On flight day 7, Leestma and Sullivan, assisted by McBride, donned their spacesuits and began their spacewalk. After gathering their tools, the two translated down to the rear of the cargo bay to the ORS station. With Sullivan documenting and assisting with the activity, Leestma installed the valve assembly into the simulated Landsat propulsion plumbing. After completing the ORS objectives, Leestma and Sullivan proceeded back toward the airlock, stopping first at the Ku antenna where Sullivan secured it in place. They returned inside after a spacewalk that lasted 3 hours and 29 minutes, and the crew brought Challenger’s cabin pressure back up to 14.7 psi.

During their final full day in space, Challenger’s crew tidied the cabin for reentry and completed the final SIR-B and other Earth observations. On Oct. 13, the astronauts closed the payload bay doors and fired the OMS engines over Australia to begin the descent back to Earth. Because of the mission’s 57-degree inclination, the reentry path took Challenger and its crew over the eastern United States, another Shuttle first. Crippen guided the orbiter to a smooth landing at KSC, completing a flight of 8 days, 5 hours, and 24 minutes, the longest mission of Challenger’s short career. The crew had traveled nearly 3.3 million miles and completed 133 orbits around the Earth.
Left: Missing insulation from Challenger’s right hand Orbiter Maneuvering System pod as seen after landing. Middle: Missing tile from the underside of Challenger’s left wing. Right: Damage to tiles on Challenger’s left wing.
As noted above, on the mission’s first day in space the crew described a missing strip of FRSI from the right-hand OMS pod. Engineers noted additional damage to Challenger’s Thermal Protection System (TPS) after the landing, including several tiles on the underside the vehicle’s left wing damaged and one tile missing entirely, presumably lost during reentry. Engineers determined that the water proofing used throughout the TPS that allowed debonding of the tiles as the culprit for the missing tile. To correct the problem, workers removed and replaced over 4,000 tiles, adding a new water proofing agent to preclude the recurrence of the problem on future missions.
Read recollections of the STS-41G mission by Crippen, McBride, Sullivan, Ride, and Leestma in their oral histories with the JSC History Office. Enjoy the crew’s narration of a video about the STS-41G mission.

NASA will provide live coverage of prelaunch and launch activities for Europa Clipper, the agency’s mission to explore Jupiter’s icy moon Europa. NASA is targeting launch at 12:31 p.m. EDT Thursday, Oct. 10, on a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
Beyond Earth, Jupiter’s moon Europa is considered one of the solar system’s most promising potentially habitable environments. After an approximately 1.8-billion-mile journey, Europa Clipper will enter orbit around Jupiter in April 2030, where the spacecraft will conduct a detailed survey of Europa to determine whether the icy world could have conditions suitable for life. Europa Clipper is the largest spacecraft NASA has ever developed for a planetary mission. It carries a suite of nine instruments along with a gravity experiment that will investigate an ocean beneath Europa’s surface, which scientists believe contains twice as much liquid water as Earth’s oceans.
