      NASA astronaut Don Pettit poses for a crew portrait at the Gagarin Cosmonaut Training Center.NASA During his fourth mission to the International Space Station, NASA astronaut Don Pettit will serve as a flight engineer and member of the Expedition 71/72 crew. After blasting off to space, Pettit will conduct scientific investigations and technology demonstrations to help prepare crew for future space missions.
      Pettit will launch on the Roscosmos Soyuz MS-26 spacecraft in September 2024, accompanied by Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner. The trio will spend approximately six months aboard the orbital laboratory.
      NASA selected Pettit as an astronaut in 1996. A veteran of three spaceflights, he made integral advancements in technology and demonstrations for human exploration. He served as a science officer for Expedition 6 in 2003, operated the robotic arm for STS-126 space shuttle Endeavour in 2008, and served as a flight engineer for Expedition 30/31 in 2012. Pettit has logged 370 days in space and conducted two spacewalks totaling 13 hours and 17 minutes.
      The Expedition 6 crew launched on STS-113 space shuttle Endeavour expecting to return on STS-114 space shuttle Discovery after a two and a half month mission. Following the space shuttle Columbia accident that grounded the shuttle fleet, the crew returned on the Soyuz TMA-1 spacecraft after five and a half months, landing in Kazakhstan. On his next 16-day mission, STS-126, Pettit helped expand the living quarters of the space station and installed a regenerative life support system to reclaim potable water from urine. During Expedition 30/31, Pettit also captured the first commercial cargo spacecraft, the SpaceX Dragon, using the robotic arm.
      A native from Silverton, Oregon, Pettit holds a bachelor’s degree in chemical engineering from Oregon State University, Corvallis, and a doctorate in chemical engineering from the University of Arizona, Tucson. Prior to his career with NASA, Pettit worked as a staff scientist at the Los Alamos National Laboratory in New Mexico.
      For more than two decades, humans have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that are not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA is able to focus more of its resources on deep space missions to the Moon and Mars.

      NASA and the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer) mission team have won the National Aeronautic Association’s (NAA) Robert J. Collier Trophy. NAA awards the trophy annually for what it determines is “the greatest achievement in aerospace and astronautics in America.” The OSIRIS-REx team will be celebrated at an award dinner on June 13, 2024, in Washington, D.C. 
      The NAA bestowed the Robert J. Collier Trophy on the team behind NASA’s OSIRIS-REx, acknowledging the mission’s place in aerospace history by being the first U.S. mission to collect a sample from an asteroid and deliver it to Earth for study.
      A top-down view of the OSIRIS-REx Touch-and-Go-Sample-Acquisition-Mechanism (TAGSAM) head with the lid removed, revealing the remainder of the asteroid sample inside. Erika Blumenfeld, creative lead for the Advanced Imaging and Visualization of Astromaterials (AIVA) and Joe Aebersold, project management lead, captured this picture using manual high-resolution precision photography and a semi-automated focus stacking procedure. The result is an image that can be zoomed in on to show extreme detail of the sample. The remaining sample material includes dust and rocks up to about .4 in (one cm) in size.NASA/Erika Blumenfeld & Joseph Aebersold “Congratulations to the OSIRIS-REx team on this well-deserved honor,” said NASA Administrator Bill Nelson. “By successfully designing, building, and carrying out the first U.S. mission to collect an asteroid sample, NASA proved once again that we do big things. Things that inspire the world. We look forward to the incredible science to come that will tell us more about our solar system and help protect humanity here on Earth.”
      Established more than a century ago, the award has marked major achievements in the timeline of flight, including Orville Wright in 1913 for developing the automatic stabilizer; Air Force test pilot Chuck Yeager for his sound-barrier-breaking 1947 flight of the X-1 rocket plane; the crews of NASA’s Apollo 8, 11, and 15 for their missions to the Moon in the late 1960s and early ’70s; and NASA’s Ingenuity Mars Helicopter.
      The OSIRIS-REx team includes NASA’s Goddard Space Flight Center in Greenbelt, Maryland; Lockheed Martin in Littleton, Colorado; University of Arizona, Tucson; and KinetX in Tempe, Arizona.
      The sample from the ancient asteroid Bennu that OSIRIS-REx delivered to Earth in September 2023 will give researchers worldwide a glimpse into the earliest days of our solar system, offering insights into planet formation and the origin of organics essential for life on Earth. Data collected by the spacecraft combined with future analysis of the Bennu sample will also aid our understanding of asteroids that could impact Earth.
      The Collier Trophy adds to the recent Robert H. Goddard Memorial Trophy received by NASA’s OSIRIS-REx team in March 2024.
      Following its successful sample return, the OSIRIS-REx spacecraft was renamed OSIRIS-APEX and will now enter an extended mission to visit and study near-Earth asteroid Apophis in 2029.
      NASA Goddard provides overall mission management, systems engineering, and the safety and mission assurance for OSIRIS-REx. Dante Lauretta of the University of Arizona, Tucson, is the principal investigator. The university leads the science team and the mission’s science observation planning and data processing. Lockheed Martin Space in Littleton, Colorado, built the spacecraft and provides flight operations. Goddard and KinetX Aerospace are responsible for navigating the OSIRIS-REx spacecraft. Processing and curation for OSIRIS-REx’s Bennu sample takes place at NASA’s Johnson Space Center in Houston. International partnerships on this mission include the OSIRIS-REx Laser Altimeter instrument from CSA (the Canadian Space Agency) and asteroid sample science collaboration with JAXA’s (the Japan Aerospace Exploration Agency) Hayabusa2 mission. OSIRIS-REx is the third mission in NASA’s New Frontiers Program, managed by the agency’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate at NASA Headquarters in Washington.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA’s OSIRIS-REx team was selected as the winner of the National Space Club and Foundation’s 2024 Dr. Robert H. Goddard Memorial Trophy for their tremendous work on the first U.S. mission to bring an asteroid sample to Earth. The winning team  received the award at the 67th Annual Robert H. Goddard Memorial Dinner at the Washington Hilton Hotel on March 22, 2024.
      The sample return capsule from NASA’s OSIRIS-REx mission is seen shortly after touching down in the desert, Sunday, Sept. 24, 2023, at the Department of Defense’s Utah Test and Training Range. The sample was collected from the asteroid Bennu in October 2020 by NASA’s OSIRIS-REx spacecraft. NASA/Keegan Barber The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer) team includes NASA’s Goddard Space Flight Center in Greenbelt, Maryland; Lockheed Martin in Littleton, Colorado; University of Arizona, Tucson and KinetX in Tempe, Arizona.
      The trophy is National Space Club’s highest honor and presented annually to the individual or group who has made a substantial contribution to U.S. leadership in astronautics or rocketry.
      “The OSIRIS-REx team’s successful delivery of the asteroid Bennu sample to Earth will enable important scientific discoveries for generations to come,” said Lori Glaze, director of the Planetary Science Division at NASA Headquarters in Washington. “I’m so pleased to see the mission team recognized with the Robert H. Goddard Memorial Trophy for their accomplishments.”
      Making U.S. History
      Following its launch in 2016, the OSIRIS-REx mission made U.S. space history when it became the first U.S. spacecraft to touch an asteroid and capture a sample on Oct. 20, 2020, and again when it successfully returned with the sample to Earth on Sept. 24, 2023.
      The sample, which is the largest asteroid sample ever delivered to Earth, is from the ancient asteroid Bennu and will give researchers worldwide a glimpse into the earliest days of our solar system, offering insights into planet formation and the origin of organics that led to life on Earth. Data collected by the spacecraft combined with future analysis of the Bennu sample will also aid our understanding of asteroids that can impact Earth.
      The OSIRIS-REx mission conducted unprecedented centimeter-scale mapping of Bennu, surpassing precision levels achieved for any other planetary body and setting three Guinness World Records for: smallest object orbited by a spacecraft, closest orbit of an asteroid and highest resolution satellite map of any planetary body.
      “The OSIRIS-REx mission rewrote U.S. space exploration history,” said Joe Vealencis, president, NSCF. “The data the spacecraft collected, plus all that we have yet to uncover from the sample it brought back, means scientists and engineers will be reaping the benefits of this mission for years to come.”
      The Mission Continues
      Following its successful sample return, the OSIRIS-REx spacecraft was renamed OSIRIS-APEX and will now enter an extended mission to visit and study near-Earth asteroid Apophis in 2029.
      OSIRIS-REx’s success was made possible by the unique contributions of over 1,000 individuals from government and mission partners like the science lead at the University of Arizona, the project team at NASA’s Goddard Space Flight Center, the curation team at NASA’s Johnson Space Center, spacecraft design, operations, and recovery by Lockheed Martin, guidance and navigation at KinetX, and the launch provider at United Launch Alliance.
      OSIRIS-REx is the third mission in NASA’s New Frontiers Program, managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the Science Mission Directorate at NASA Headquarters in Washington.

      NASA’s Tiny BurstCube Mission Launches to Study Cosmic Blasts
      BurstCube, shown in this artist’s concept, will orbit Earth as it hunts for short gamma-ray bursts. NASA’s Goddard Space Flight Center Conceptual Image Lab NASA’s BurstCube, a shoebox-sized satellite designed to study the universe’s most powerful explosions, is on its way to the International Space Station.
      The spacecraft travels aboard SpaceX’s 30th Commercial Resupply Services mission, which lifted off at 4:55 p.m. EDT on Thursday, March 21, from Launch Complex 40 at Cape Canaveral Space Force Station in Florida. After arriving at the station, BurstCube will be unpacked and later released into orbit, where it will detect, locate, and study short gamma-ray bursts – brief flashes of high-energy light.
      “BurstCube may be small, but in addition to investigating these extreme events, it’s testing new technology and providing important experience for early career astronomers and aerospace engineers,” said Jeremy Perkins, BurstCube’s principal investigator at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

      Download high-resolution images and videos of BurstCube.

      Short gamma-ray bursts usually occur after the collisions of neutron stars, the superdense remnants of massive stars that exploded in supernovae. The neutron stars can also emit gravitational waves, ripples in the fabric of space-time, as they spiral together.
      Astronomers are interested in studying gamma-ray bursts using both light and gravitational waves because each can teach them about different aspects of the event. This approach is part of a new way of understanding the cosmos called multimessenger astronomy.
      The collisions that create short gamma-ray bursts also produce heavy elements like gold and iodine, an essential ingredient for life as we know it.
      Currently, the only joint observation of gravitational waves and light from the same event – called GW170817 – was in 2017. It was a watershed moment in multimessenger astronomy, and the scientific community has been hoping and preparing for additional concurrent discoveries since.
      “BurstCube’s detectors are angled to allow us to detect and localize events over a wide area of the sky,” said Israel Martinez, research scientist and BurstCube team member at the University of Maryland, College Park and Goddard. “Our current gamma-ray missions can only see about 70% of the sky at any moment because Earth blocks their view. Increasing our coverage with satellites like BurstCube improves the odds we’ll catch more bursts coincident with gravitational wave detections.”
      BurstCube’s main instrument detects gamma rays with energies ranging from 50,000 to 1 million electron volts. (For comparison, visible light ranges between 2 and 3 electron volts.)
      When a gamma ray enters one of BurstCube’s four detectors, it encounters a cesium iodide layer called a scintillator, which converts it into visible light. The light then enters another layer, an array of 116 silicon photomultipliers, that converts it into a pulse of electrons, which is what BurstCube measures. For each gamma ray, the team sees one pulse in the instrument readout that provides the precise arrival time and energy. The angled detectors inform the team of the general direction of the event.
      BurstCube belongs to a class of spacecraft called CubeSats. These small satellites come in a range of standard sizes based on a cube measuring 10 centimeters (3.9 inches) across. CubeSats provide cost-effective access to space to facilitate groundbreaking science, test new technologies, and help educate the next generation of scientists and engineers in mission development, construction, and testing.
      Engineers attach BurstCube to the platform of a thermal vacuum chamber at Goddard ahead of testing. NASA/Sophia Roberts “We were able to order many of BurstCube’s parts, like solar panels and other off-the-shelf components, which are becoming standardized for CubeSats,” said Julie Cox, a BurstCube mechanical engineer at Goddard. “That allowed us to focus on the mission’s novel aspects, like the made-in-house components and the instrument, which will demonstrate how a new generation of miniaturized gamma-ray detectors work in space.”
      BurstCube is led by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. It’s funded by the Science Mission Directorate’s Astrophysics Division at NASA Headquarters. The BurstCube collaboration includes: the University of Alabama in Huntsville; the University of Maryland, College Park; the University of the Virgin Islands; the Universities Space Research Association in Washington; the Naval Research Laboratory in Washington; and NASA’s Marshall Space Flight Center in Huntsville.
