      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      This version of a mosaic captured by the star tracker cameras aboard NASA’s Europa Clipper on Dec. 4, 2024, features the names of stars within view of the cameras. NASA/JPL-Caltech This mosaic of a star field was made from three images captured Dec. 4, 2024, by star tracker cameras aboard NASA’s Europa Clipper spacecraft. Showing part of the constel-lation Corvus, it’s the first imagery of space the orbiter has captured since its launch on Oct. 14, 2024.NASA/JPL-Caltech The spacecraft’s star trackers help engineers orient the orbiter throughout its long journey to Jupiter’s icy moon Europa.
      Three months after its launch from NASA’s Kennedy Space Center in Florida, the agency’s Europa Clipper has another 1.6 billion miles (2.6 billion kilometers) to go before it reaches Jupiter’s orbit in 2030 to take close-up images of the icy moon Europa with science cameras.
      Meanwhile, a set of cameras serving a different purpose is snapping photos in the space between Earth and Jupiter. Called star trackers, the two imagers look for stars and use them like a compass to help mission controllers know the exact orientation of the spacecraft — information critical for pointing telecommunications antennas toward Earth and sending data back and forth smoothly.
      In early December, the pair of star trackers (formally known as the stellar reference units) captured and transmitted Europa Clipper’s first imagery of space. The picture, composed of three shots, shows tiny pinpricks of light from stars 150 to 300 light-years away. The starfield represents only about 0.1% of the full sky around the spacecraft, but by mapping the stars in just that small slice of sky, the orbiter is able to determine where it is pointed and orient itself correctly.
      The starfield includes the four brightest stars — Gienah, Algorab, Kraz, and Alchiba — of the constellation Corvus, which is Latin for “crow,” a bird in Greek mythology that was associated with Apollo.
      Engineers on NASA’s Europa Clipper mission work with the spacecraft’s star trackers in a clean room at the agency’s Jet Propulsion Laboratory in 2022. Used for orienting the spacecraft, the star trackers are seen here with red covers to protect their lenses.NASA/JPL-Caltech Hardware Checkout
      Besides being interesting to stargazers, the photos signal the successful checkout of the star trackers. The spacecraft checkout phase has been going on since Europa Clipper launched on a SpaceX Falcon Heavy rocket on Oct. 14, 2024.
      “The star trackers are engineering hardware and are always taking images, which are processed on board,” said Joanie Noonan of NASA’s Jet Propulsion Laboratory in Southern California, who leads the mission’s guidance, navigation and control operations. “We usually don’t downlink photos from the trackers, but we did in this case because it’s a really good way to make sure the hardware — including the cameras and their lenses — made it safely through launch.”
      Pointing the spacecraft correctly is not about navigation, which is a separate operation. But orientation using the star trackers is critical for telecommunications as well as for the science operations of the mission. Engineers need to know where the science instruments are pointed. That includes the sophisticated Europa Imaging System (EIS), which will collect images that will help scientists map and examine the moon’s mysterious fractures, ridges, and valleys. For at least the next three years, EIS has its protective covers closed.
      Europa Clipper carries nine science instruments, plus the telecommunications equipment that will be used for a gravity science investigation. During the mission’s 49 flybys of Europa, the suite will gather data that will tell scientists if the icy moon and its internal ocean have the conditions to harbor life.
      The spacecraft already is 53 million miles (85 million kilometers) from Earth, zipping along at 17 miles per second (27 kilometers per second) relative to the Sun, and soon will fly by Mars. On March 1, engineers will steer the craft in a loop around the Red Planet, using its gravity to gain speed.
      More About Europa Clipper
      Europa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.
      Managed by Caltech in Pasadena, California, JPL leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, for NASA’s Science Mission Directorate in Washington. APL designed the main spacecraft body in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland, NASA’s Marshall Space Flight Center in Huntsville, Alabama, and Langley Research Center in Hampton, Virginia. The Planetary Missions Program Office at Marshall executes program management of the Europa Clipper mission. NASA’s Launch Services Program, based at Kennedy, managed the launch service for the Europa Clipper spacecraft.

      The first shuttle mission of 1995, STS-63 included several historic firsts. As part of Phase 1 of the International Space Station program, space shuttle Discovery’s 20th flight conducted the first shuttle rendezvous with the Mir space station, in preparation for future dockings. The six-person crew included Commander James Wetherbee, Pilot Eileen Collins – the first woman to pilot a space shuttle mission – Payload Commander Bernard Harris, and Mission Specialists Michael Foale, Janice Voss, and Vladimir Titov. The spacewalk conducted during the mission included the first African American and the first British born astronauts to walk in space. The crew conducted 20 science and technology experiments aboard the third flight of the Spacehab module. The astronauts deployed and retrieved the SPARTAN-204 satellite that during its two-day free flight carried out observations of galactic objects using an ultraviolet instrument. 

      The STS-63 crew patch. The STS-63 crew of Janice Voss, front row left, Eileen Collins, James Wetherbee, and Vladimir Titov; Bernard Harris, back row left, and Michael Foale. The Shuttle-Mir program patch. NASA announced the six-person STS-63 crew in September 1993 for a mission then expected to fly in May 1994. Wetherbee, selected by NASA in 1984, had already flown twice in space, as pilot on STS-32 and commander of STS-52. For Collins, selected in the class of 1990 as the first woman shuttle pilot, STS-63 marked her first spaceflight. Also selected in 1990, Harris had flown previously on STS-55 and Voss on STS-57. Foale, selected as an astronaut in 1987, had flown previously on STS-45 and STS-56. Titov, selected as a cosmonaut in 1976, had flown two previous spaceflights – a two-day aborted docking mission to Salyut-7 and the first year-long mission to Mir – and survived a launch pad abort. He served as backup to Sergei Krikalev on STS-60, who now served as Titov’s backup. 

      Space shuttle Discovery rolls out to Launch Pad 39B. The STS-63 crew during the Terminal Countdown Demonstration Test in the White Room of Launch Pad 39B. The STS-63 astronauts walk out of crew quarters for the van ride out to the launch pad. Space shuttle Discovery arrived back at NASA’s Kennedy Space Center in Florida on Sept. 27, 1994, after a ferry flight from California following its previous mission, STS-64. Workers towed it to the Orbiter Processing Facility the next day. Following installation of the Spacehab, SPARTAN, and other payloads, on Jan. 5, 1995, workers rolled Discovery from the processing facility to the Vehicle Assembly Building for mating with an external tank and twin solid rocket boosters. Rollout to Launch Pad 39B took place on Jan. 10. On Jan. 17-18, teams conducted the Terminal Countdown Demonstration Test, a dress rehearsal for the countdown to launch planned for Feb. 2, with the astronaut crew participating in the final few hours as they would on launch day. They returned to Kennedy on Jan. 29 for final pre-launch preparations. On Feb. 2, launch teams called a 24-hour scrub to allow time to replace a failed inertial measurement unit aboard Discovery. 

      Launch of space shuttle Discovery on mission STS-63. STS-63 Commander James Wetherbee on Discovery’s flight deck. STS-63 Pilot Eileen Collins on Discovery’s flight deck. On Feb. 3, Discovery and its six-person crew lifted off from Launch Pad 39B at 12:22 a.m. EST, the time dictated by orbital mechanics – Discovery had to launch into the plane of Mir’s orbit. Within 8.5 minutes, Discovery had reached orbit, for the first time in shuttle history at an inclination of 51.6 degrees, again to match Mir’s trajectory. Early in the mission, one of Discovery’s 44 attitude control thrusters failed and two others developed minor but persistent leaks, threatening the Mir rendezvous.  

      View of the Spacehab module in Discovery’s payload bay. The SPARTAN-204 satellite attached to the remote manipulator system or robotic arm during the flight day two operations. On the mission’s first day in space, Harris and Titov activated the Spacehab module and several of its experiments. Wetherbee and Collins performed the first of five maneuvers to bring Discovery within 46 miles of Mir for the final rendezvous on flight day four. Teams on the ground worked with the astronauts to resolve the troublesome thruster problems to ensure a safe approach to the planned 33 feet. On flight day 2, as those activities continued, Titov grappled the SPARTAN satellite with the shuttle’s robotic arm and lifted it out of the payload bay. Scientists used the ultraviolet instrument aboard SPARTAN to investigate the ultraviolet glow around the orbiter and the aftereffects of thruster firings. The tests complete, Titov placed SPARTAN back in the payload bay.

On flight day three, the astronauts continued working on science experiments while Wetherbee and Collins completed several more burns for the rendezvous on flight day four, the thruster issues resolved to allow the close approach to 33 feet. Flying Discovery manually from the aft flight deck, and assisted by his crew mates, Wetherbee slowly brought the shuttle to within 33 feet of the Kristall module of the space station. The STS-63 crew communicated with the Mir-17 crew of Aleksandr Viktorenko, Elena Kondakova, and Valeri Polyakov via VHF radio, and the crews could see each other through their respective spacecraft windows. After station-keeping for about 10 minutes, Wetherbee slowly backed Discovery away from Mir to a distance of 450 feet. He flew a complete circle around Mir before conducting a final separation maneuver.

On the mission’s fifth day, Titov once again grappled SPARTAN with the robotic arm, but this time after raising it above the payload bay, he released the satellite to begin its two-day free flight. Wetherbee steered Discovery away from the departing satellite. During its free flight, the far ultraviolet imaging spectrograph aboard SPARTAN recorded about 40 hours of observations of galactic dust clouds. During this time, the astronauts aboard the shuttle continued work on the 20 experiments in Spacehab and prepared for the upcoming spacewalk. 

      STS-63 crew member Janice Voss operates the remote manipulator system during the retrieval of the SPARTAN-204 satellite. STS-63 astronauts Bernard Harris, left, and Michael Foale at the start of their spacewalk. Wetherbee and the crew flew the second rendezvous of the mission on flight day seven to retrieve SPARTAN. Voss operated the robotic arm to capture and stow the satellite in the payload bay following its 43-hour free flight. Meanwhile, Foale and Harris suited up in the shuttle’s airlock and spent four hours breathing pure oxygen to rid their bodies of nitrogen to prevent decompression sickness, also known as the bends, when they reduced their spacesuit pressures for the spacewalk.

Foale and Harris exited the airlock minutes after Voss safely stowed SPARTAN. With Titov operating the robotic arm, Harris and Foale climbed aboard its foot restraint to begin the first phase of the spacewalk, testing modifications to the spacesuits for their thermal characteristics. Titov lifted them well above the payload bay and the two spacewalkers stopped moving for about 15 minutes, until their hands and feet got cold. The spacewalk then continued into its second portion, the mass handling activity. Titov steered Foale above the SPARTAN where he lifted the satellite up and handed it off to Harris anchored in the payload bay. Harris then moved it around in different directions to characterize handling of the 2,600-pound satellite. Foale and Harris returned to the airlock after a spacewalk lasting 4 hours 39 minutes. 

      The STS-63 astronauts pose for their inflight crew photo. Discovery makes a successful landing at NASA’s Kennedy Space Center in Florida. The day following the spacewalk, the STS-63 crew finished the science experiments, closed down the Spacehab module, and held a news conference with reporters on the ground. Wetherbee and Collins tested Discovery’s thrusters and aerodynamic surfaces in preparation for the following day’s reentry and landing. The next day, on Feb. 11, they closed Discovery’s payload bay doors and put on their launch and entry suits. Wetherbee guided Discovery to a smooth landing on Kennedy’s Shuttle Landing Facility, ending the historic mission after eight days, six hours, and 28 minutes. They orbited the Earth 129 times. The mission paved the way for nine shuttle dockings with Mir beginning with STS-71, and 37 with the International Space Station. Workers at Kennedy towed Discovery to the processing facility to prepare it for its next mission, STS-70 in July 1995. 
      Over the next three years, Wetherbee, Collins, Foale, and Titov all returned to Mir during visiting shuttle flights, with Foale staying aboard as the NASA-5 long-duration crew member. Between 2001 and 2005, Wetherbee, Collins, and Foale also visited the International Space Station. Wetherbee commanded two assembly flights, Collins commanded the return to flight mission after the Columbia accident, and Foale commanded Expedition 8.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      A massive hotspot — larger the Earth’s Lake Superior — can be seen just to the right of Io’s south pole in this annotated image taken by the JIRAM infrared imager aboard NASA’s Juno on Dec. 27, 2024, during the spacecraft’s flyby of the Jovian moon. NASA/JPL-Caltech/SwRI/ASI/INAF/JIRAM Even by the standards of Io, the most volcanic celestial body in the solar system, recent events observed on the Jovian moon are extreme.
      Scientists with NASA’s Juno mission have discovered a volcanic hot spot in the southern hemisphere of Jupiter’s moon Io. The hot spot is not only larger than Earth’s Lake Superior, but it also belches out eruptions six times the total energy of all the world’s power plants. The discovery of this massive feature comes courtesy of Juno’s Jovian Infrared Auroral Mapper (JIRAM) instrument, contributed by the Italian Space Agency.
      “Juno had two really close flybys of Io during Juno’s extended mission,” said the mission’s principal investigator, Scott Bolton of the Southwest Research Institute in San Antonio. “And while each flyby provided data on the tormented moon that exceeded our expectations, the data from this latest — and more distant — flyby really blew our minds. This is the most powerful volcanic event ever recorded on the most volcanic world in our solar system — so that’s really saying something.”
      The source of Io’s torment: Jupiter. About the size of Earth’s Moon, Io is extremely close to the mammoth gas giant, and its elliptical orbit whips it around Jupiter once every 42.5 hours. As the distance varies, so does the planet’s gravitational pull, which leads to the moon being relentlessly squeezed. The result: immense energy from frictional heating that melts portions of Io’s interior, resulting in a seemingly endless series of lava plumes and ash venting into its atmosphere from the estimated 400 volcanoes that riddle its surface.
      Close Flybys
      Designed to capture the infrared light (which isn’t visible to the human eye) emerging from deep inside Jupiter, JIRAM probes the gas giant’s weather layer, peering 30 to 45 miles (50 to 70 kilometers) below its cloud tops. But since NASA extended Juno’s mission, the team has also used the instrument to study the moons Io, Europa, Ganymede, and Callisto.
      Images of Io captured in 2024 by the JunoCam imager aboard NASA’s Juno show signif-icant and visible surface changes (indicated by the arrows) near the Jovian moon’s south pole. These changes occurred between the 66th and 68th perijove, or the point during Juno’s orbit when it is closest to Jupiter.Image data: NASA/JPL-Caltech/SwRI/MSSS Image processing by Jason Perry During its extended mission, Juno’s trajectory passes by Io every other orbit, flying over the same part of the moon each time. Previously, the spacecraft made close flybys of Io in December 2023 and February 2024, getting within about 930 miles (1,500 kilometers) of its surface. The latest flyby took place on Dec. 27, 2024, bringing the spacecraft within about 46,200 miles (74,400 kilometers) of the moon, with the infrared instrument trained on Io’s southern hemisphere.
      Io Brings the Heat
      “JIRAM detected an event of extreme infrared radiance — a massive hot spot — in Io’s southern hemisphere so strong that it saturated our detector,” said Alessandro Mura, a Juno co-investigator from the National Institute for Astrophysics in Rome. “However, we have evidence what we detected is actually a few closely spaced hot spots that emitted at the same time, suggestive of a subsurface vast magma chamber system. The data supports that this is the most intense volcanic eruption ever recorded on Io.”
      The JIRAM science team estimates the as-yet-unnamed feature spans 40,000 square miles (100,000 square kilometers). The previous record holder was Io’s Loki Patera, a lava lake of about 7,700 square miles (20,000 square kilometers). The total power value of the new hot spot’s radiance measured well above 80 trillion watts.
      Picture This
      The feature was also captured by the mission’s JunoCam visible light camera. The team compared JunoCam images from the two previous Io flybys with those the instrument collected on Dec. 27. And while these most recent images are of lower resolution since Juno was farther away, the relative changes in surface coloring around the newly discovered hot spot were clear. Such changes in Io’s surface are known in the planetary science community to be associated with hot spots and volcanic activity.
      An eruption of this magnitude is likely to leave long-lived signatures. Other large eruptions on Io have created varied features, such as pyroclastic deposits (composed rock fragments spewed out by a volcano), small lava flows that may be fed by fissures, and volcanic-plume deposits rich in sulfur and sulfur dioxide.
      Juno will use an upcoming, more distant flyby of Io on March 3 to look at the hot spot again and search for changes in the landscape. Earth-based observations of this region of the moon may also be possible.  
      “While it is always great to witness events that rewrite the record books, this new hot spot can potentially do much more,” said Bolton. “The intriguing feature could improve our understanding of volcanism not only on Io but on other worlds as well.”
      More About Juno
      NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Juno mission for the principal investigator, Scott Bolton, of the Southwest Research Institute in San Antonio. Juno is part of NASA’s New Frontiers Program, which is managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington. The Italian Space Agency (ASI) funded the Jovian InfraRed Auroral Mapper. Lockheed Martin Space in Denver built and operates the spacecraft. Various other institutions around the U.S. provided several of the other scientific instruments on Juno.
