      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 is celebrating the Sun during the Heliophysics Big Year, which extends through the end of 2024. You can get involved to help us learn more about our star and its influence on our planet. With exciting experiments happening during the total solar eclipse that will cross North America on April 8, to widespread investigations going on throughout the year, keep reading to find a project that’s right for you.
      The dark band that runs from Mexico into Texas and all the way to Maine and Maritime Canada shows the path of totality for the April 8, 2024, eclipse. This is the area where people on Earth can witness a total eclipse of the Sun. Outside of this path, observers may see a partial eclipse, with the amount of the Sun being blocked by the Moon decreasing with distance from the path.  NASA/Scientific Visualization Studio/Michala Garrison; Eclipse Calculations By Ernie Wright, NASA Goddard Space Flight Center What Is Citizen Science (Also Called Participatory Science)?
      NASA defines citizen science as “a form of open collaboration in which individuals or organizations participate in the scientific process in various ways” from collecting and analyzing data to making discoveries and solving problems. ”Citizen” here refers to citizens of planet Earth, and these projects are open to everyone, regardless of country of birth or legal citizenship status.
      NASA sponsors citizen science projects across all five areas of research that it pursues: Earth science, planetary science, astrophysics, biological and physical sciences, and heliophysics. And yes, there are a few projects that are focused on the April 8 solar eclipse!
      What You Can Do
      Depending which project you join, you might:
      Observe and record in pictures or words natural phenomena like clouds, animal noises, or a solar eclipse. Learn how to recognize or classify patterns in data or pictures of a comet or solar jet. Learn how to build and use scientific equipment like radio telescopes or ham radios. Your contribution may be a large or small piece of the picture, but what you do as part of a NASA citizen science project is essential to answering the research question or need that the project addresses. And while you’re contributing to science, you might also develop new skills and make friends. You can read about some project participants – and what motivates them – in these profiles.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      Europa Clipper is seen in the 25-Foot Space Simulator at JPL in February, before the start of thermal vacuum testing. A battery of tests ensures that the NASA spacecraft can withstand the extreme hot, cold, and airless environment of space. NASA/JPL-Caltech A gantlet of tests prepared the spacecraft for its challenging trip to the Jupiter system, where it will explore the icy moon Europa and its subsurface ocean.
      In less than six months, NASA is set to launch Europa Clipper on a 1.6-billion-mile (2.6-billion-kilometer) voyage to Jupiter’s ocean moon Europa. From the wild vibrations of the rocket ride to the intense heat and cold of space to the punishing radiation of Jupiter, it will be a journey of extremes. The spacecraft was recently put through a series of hard-core tests at the agency’s Jet Propulsion Laboratory in Southern California to ensure it’s up to the challenge.
      Called environmental testing, the battery of trials simulates the environment that the spacecraft will face, subjecting it to shaking, chilling, airlessness, electromagnetic fields, and more.
      NASA’s Europa Clipper is seen being lifted into the Space Simulator at JPL in February. Thermal vacuum testing, which lasted 16 days, ensures that the spacecraft will withstand the harsh conditions of space. NASA/JPL-Caltech NASA’s Europa Clipper is visible in the clean room of High Bay 1 within JPL’s Spacecraft Assembly Facility in January. The tent around the spacecraft was erected to support electromagnetic testing, which was part of a regimen of environmental tests. NASA/JPL-Caltech “These were the last big tests to find any flaws,” said JPL’s Jordan Evans, the mission’s project manager. “Our engineers executed a well-designed and challenging set of tests that put the system through its paces. What we found is that the spacecraft can handle the environments that it will see during and after launch. The system performed very well and operates as expected.”
      The Gantlet
      The most recent environmental test for Europa Clipper was also one of the most elaborate, requiring 16 days to complete. The spacecraft is the largest NASA has ever built for a planetary mission and one of the largest ever to squeeze into JPL’s historic 85-foot-tall, 25-foot-wide (26-meter-by-8-meter) thermal vacuum chamber (TVAC). Known as the 25-foot Space Simulator, the chamber creates a near-perfect vacuum inside to mimic the airless environment of space.
      At the same time, engineers subjected the hardware to the high temperatures it will experience on the side of Europa Clipper that faces the Sun while the spacecraft is close to Earth. Beams from powerful lamps at the base of the Space Simulator bounced off a massive mirror at its top to mimic the heat the spacecraft will endure.
      To simulate the journey away from the Sun, the lamps were dimmed and liquid nitrogen filled tubes in the chamber walls to chill them to temperatures replicating space. The team then gauged whether the spacecraft could warm itself, monitoring it with about 500 temperature sensors, each of which had been attached by hand.
      Watch as engineers and technicians move NASA’s Europa Clipper into the thermal vacuum chamber at JPL in February 2024.
      Credit: NASA/JPL-Caltech TVAC marked the culmination of environmental testing, which included a regimen of tests to ensure the electrical and magnetic components that make up the spacecraft don’t interfere with one another.
      The orbiter also underwent vibration, shock, and acoustics testing. During vibration testing, the spacecraft was shaken repeatedly – up and down and side to side – the same way it will be jostled aboard the SpaceX Falcon Heavy rocket during liftoff. Shock testing involved pyrotechnics to mimic the explosive jolt the spacecraft will get when it separates from the rocket to fly its mission. Finally, acoustic testing ensured that Europa Clipper can withstand the noise of launch, when the rumbling of the rocket is so loud it can damage the spacecraft if it’s not sturdy enough.
      “There still is work to be done, but we’re on track for an on-time launch,” Evans said. “And the fact that this testing was so successful is a huge positive and helps us rest more easily.”
      Looking to Launch
      Later this spring, the spacecraft will be shipped to NASA’s Kennedy Space Center in Florida. There, teams of engineers and technicians will carry out final preparations with eyes on the clock. Europa Clipper’s launch period opens Oct. 10.
      After liftoff, the spacecraft will zip toward Mars, and in late February 2025, it will be close enough to use the Red Planet’s gravitational force for added momentum. From there, the solar-powered spacecraft will swing back toward Earth to get another slingshot boost – from our own planet’s gravitational field – in December 2026.
      Then it’s on to the outer solar system, where Europa Clipper is set to arrive at Jupiter in 2030. The spacecraft will orbit the gas giant while it flies by Europa 49 times, dipping as close as 16 miles (25 kilometers) from the moon’s surface to gather data with its powerful suite of science instruments. The information gathered will tell scientists more about the moon’s watery interior.
      More About the Mission
      Europa Clipper’s main science goal is to determine whether there are places below the surface of Jupiter’s icy moon, Europa, that could support life. The mission’s three main science objectives are to determine the thickness of the moon’s icy shell and its surface 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 (APL) 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. The Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama, executes program management of the Europa Clipper mission.

      ESA, NASA Solar Observatory Discovers Its 5,000th Comet
      On March 25, 2024, a citizen scientist in the Czech Republic spotted a comet in an image from the Solar and Heliospheric Observatory (SOHO) spacecraft, which has now been confirmed to be the 5,000th comet discovered using SOHO data. SOHO has achieved this milestone over 28 years in space, even though it was never designed to be a comet hunter.
      The 5,000th comet discovered with the Solar and Heliospheric Observatory (SOHO) spacecraft is noted by a small white box in the upper left portion of this image. A zoomed-in inset shows the comet as a faint dot between the white vertical lines. The image was taken on March 25, 2024, by SOHO’s Large Angle and Spectrometric Coronagraph (LASCO), which uses a disk to block the bright Sun and reveal faint features around it. NASA/ESA/SOHO The comet is a small body made of ice and rock that takes only a few years to orbit the Sun. It belongs to the “Marsden group” of comets. This group is thought to be related to comet 96P/Machholz (which SOHO observes when Machholz passes near the Sun every 5.3 years) and is named for the late scientist Brian Marsden who first recognized the group using SOHO observations. Only about 75 of the 5,000 comets discovered with SOHO belong to the Marsden group.
      A joint mission of ESA (European Space Agency) and NASA, SOHO launched in December 1995 to study the Sun and the dynamics in its outer atmosphere, called the corona. A science instrument on SOHO, called the Large Angle and Spectrometric Coronagraph (LASCO), uses an artificial disk to block the blinding light of the Sun so scientists can study the corona and environment immediately around the Sun.
      This also allows SOHO to do something many other spacecraft cannot – see comets flying close to the Sun, known as “sungrazing” comets or “sungrazers.” Many of these comets only brighten when they’re too close to the Sun for other observatories to see and would otherwise go undetected, lost in the bright glare of our star. While scientists expected SOHO to serendipitously find some comets during its mission, the spacecraft’s ability to spot them has made it the most prolific comet-finder in history – discovering more than half of the comets known today.
      In fact, soon after SOHO launched, people around the world began spotting so many comets in its images that mission scientists needed a way to keep track of them all. In the early 2000s, they launched the NASA-funded Sungrazer Project that allows anyone to report comets they find in SOHO images.
      This animation shows the Solar and Heliospheric Observatory’s 5,000th comet (circled) moving across the field relative to background stars. The images in this sequence were taken with the spacecraft’s Large Angle and Spectrometric Coronagraph (LASCO) instrument. NASA/ESA/SOHO SOHO’s 5,000th comet was found by Hanjie Tan, a Sungrazer Project participant who is originally from Guangzhou, China, and is currently pursuing a doctoral degree in astronomy in Prague, Czech Republic. Tan has been participating in the Sungrazer Project since he was 13 years old and is one of the project’s youngest comet discoverers.
      “Since 2009, I’ve discovered over 200 comets,” Tan said. “I got into the Sungrazer Project because I love looking for comets. It’s really exciting to be the first to see comets get bright near the Sun after they’ve been traveling through space for thousands of years.”
      Most of the 5,000 comets discovered using SOHO have been found with the help of an international cadre of volunteer comet hunters – many with no formal scientific training – participating in the Sungrazer Project.
      “Prior to the launch of the SOHO mission and the Sungrazer Project, there were only a couple dozen sungrazing comets on record – that’s all we knew existed,” said Karl Battams, a space scientist at the U.S. Naval Research Lab in Washington, D.C., and the principal investigator for the Sungrazer Project. “The fact that we’ve finally reached this milestone – 5,000 comets – is just unbelievable to me.”
      SOHO’s 5,000th comet was discovered with the help of volunteers participating in the NASA-funded Sungrazer Project.
      Credit: NASA’s Goddard Space Flight Center The vast number of comets discovered using SOHO has allowed scientists to learn more about sungrazing comets and groups of comets that orbit the Sun. Comets discovered by the Sungrazer Project have also helped scientists learn more about the Sun, by watching the comets plunge through our star’s atmosphere like small solar probes.
      “The statistics of 5,000 comets, and looking at their orbits and trajectories through space, is a super unique dataset – it’s really valuable science,” Battams said. “It’s a testament to the countless hours the project participants have put into this. We absolutely would never had reached this milestone if it wasn’t for what the project volunteers have done.”
      The Sungrazer Project is one of many opportunities that anyone can get involved with to help make discoveries with NASA during the Heliophysics Big Year, which extends through the end of 2024.
