The final pre-launch preparations for the first Meteosat Third Generation (MTG) satellite are underway. The first satellite, called MTG-I1, built by a European industrial consortium led by Thales Alenia Space carries two imagers: an advanced Flexible Combined Imager  and, in a first for Europe, a Lightning Imager that will allow the earlier detection of storms and extreme weather events, as well as improve aviation safety.  

Building on the long-standing partnership between ESA and Eumetsat, the MTG-I1 will be one of six satellites operating in a fleet, of three at a time, to ensure the continuity of data from the previous Meteosat satellites over the next 20 years. The first Meteosat was launched in 1977 and this third generation of spacecraft will be the most advanced yet, with improved image resolution and providing close to real time data for users, or ‘nowcasting’ of fast-developing, high-impact weather.

The launch is currently scheduled for the end of 2022.

The film includes soundbites from ESA Director of Earth Observation Programmes: Simonetta Cheli, ESA Meteosat Programme Manager: Paul Blythe, ESA Meteosat Third Generation Payload Manager: Donny Aminou and EUMETSAT, Meteosat Third Generation Programme Manager: Alexander Schmid.

      Three-Year Study of Young Stars with NASA’s Hubble Enters New Chapter
      In the largest and one of the most ambitious Hubble Space Telescope programs ever executed, a team of scientists and engineers collected information on almost 500 stars over a three-year period. This effort offers new insights into the stars’ formation, evolution, and impact on their surroundings. 
      This comprehensive survey, called ULLYSES (Ultraviolet Legacy Library of Young Stars as Essential Standards), was completed in December 2023, and provides a rich spectroscopic dataset obtained in ultraviolet light that astronomers will be mining for decades to come. Because ultraviolet light can only be observed from space, Hubble is the only active telescope that can accomplish this research. 
      The ULLYSES program studied two types of young stars: super-hot, massive, blue stars and cooler, redder, less massive stars than our Sun. The top panel is a Hubble Space Telescope image of a star-forming region containing massive, young, blue stars in 30 Doradus, the Tarantula Nebula. Located within the Large Magellanic Cloud, this is one of the regions observed by ULLYSES. The bottom panel shows an artist’s concept of a cooler, redder, young star that less massive than our Sun. This type of star is still gathering material from its surrounding, planet-forming disk. NASA, ESA, STScI, Francesco Paresce (INAF-IASF Bologna), Robert O’Connell (UVA), SOC-WFC3, ESO

      “I believe the ULLYSES project will be transformative, impacting overall astrophysics – from exoplanets, to the effects of massive stars on galaxy evolution, to understanding the earliest stages of the evolving universe,” said Julia Roman-Duval, Implementation Team Lead for ULLYSES at the Space Telescope Science Institute (STScI) in Baltimore, Maryland. “Aside from the specific goals of the program, the stellar data can also be used in fields of astrophysics in ways we can’t yet imagine.”
      The ULLYSES team studied 220 stars, then combined those observations with information from the Hubble archive on 275 additional stars. The program also included data from some of the world’s largest, most powerful ground-based telescopes and X-ray space telescopes. The ULLYSES dataset is made up of stellar spectra, which carry information about each star’s temperature, chemical composition, and rotation. 
      One type of stars studied under ULLYSES is super-hot, massive, blue stars. They are a million times brighter than the Sun and glow fiercely in ultraviolet light that can easily be detected by Hubble. Their spectra include key diagnostics of the speed of their powerful winds. The winds drive galaxy evolution and seed galaxies with the elements needed for life. Those elements are cooked up inside the stars’ nuclear fusion ovens and then injected into space as a star dies. ULLYSES targeted blue stars in nearby galaxies that are deficient in elements heavier than helium and hydrogen. This type of galaxy was common in the very early universe. “ULLYSES observations are a stepping stone to understanding those first stars and their winds in the universe, and how they impact the evolution of their young host galaxy,” said Roman-Duval.  
      The other star category in the ULLYSES program is young stars less massive than our Sun. Though cooler and redder than our Sun, in their formative years they unleash a torrent of high-energy radiation, including blasts of ultraviolet light and X-rays. Because they are still growing, they are gathering material from their surrounding planet-forming disks of dust and gas. The Hubble spectra include key diagnostics of the process by which they acquire their mass, including how much energy this process releases into the surrounding planet-forming disk and nearby environment. The blistering ultraviolet light from young stars affects the evolution of these disks as they form planets, as well as the chances of habitability for newborn planets. The target stars are located in nearby star-forming regions in our Milky Way galaxy.
      The ULLYSES concept was designed by a committee of experts with the goal of using Hubble to provide a legacy set of stellar observations. “ULLYSES was originally conceived as an observing program utilizing Hubble’s sensitive spectrographs. However, the program was tremendously enhanced by community-led coordinated and ancillary observations with other ground- and space-based observatories,” said Roman-Duval. “Such broad coverage allows astronomers to investigate the lives of stars in unprecedented detail and paint a more comprehensive picture of the properties of these stars and how they impact their environment.”
      To that end, STScI hosted a ULLYSES workshop March 11–14 to celebrate the beginning of a new era of research on young stars. The goal was to allow members of the astronomical community to collaborate on the data, so that they could gain momentum in the ongoing analyses, or kickstart new ideas for analysis. The workshop was one important step in exploiting this legacy spectral library to its fullest potential, fulfilling the promise of ULLYSES.
      The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, Colorado, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, Maryland, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

      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.”

      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.

      3 Min Read Order Up: High School Students Compete to Launch Their Food into Space with NASA HUNCH Culinary Competition
      High School students in chef jackets line long black tables at NASA's Langley Research Center preparing savory breakfast dishes fit for astronauts onboard the International Space Station. Credits: NASA/Angelique Herring On Monday, Feb. 26, visitors to the Integrated Engineering Services Building at NASA’s Langley Research Center in Hampton, Virginia, were greeted by the mouthwatering smell of roasted garlic, sautéed peppers and onions, fragrant herbs, and the unexpected discovery that the building’s main hallway had been turned into a pop-up kitchen for local high school students.
      These students were participants in NASA HUNCH Culinary. NASA HUNCH (High School Students United with NASA to Create Hardware) is a Project Based Learning program where high school students participate in the design and fabrication of real world valued products for NASA. HUNCH has six areas of focus that students may choose to participate in: Precision Machining, Softgoods, Design and Prototype, Food Science, Communications, and Software.
      High School students chop vegetables as they prepare their savory entry for NASA’s HUNCH Culinary Challenge.NASA/Angelique Herring The HUNCH Astronaut Culinary Program provides students the opportunity to create dishes for astronauts aboard the International Space Station. Students must create tasty recipes following a specific food processing procedure and meeting certain nutritional requirements. These dishes must meet the standards of the NASA Johnson Space Center Food Lab in Houston, Texas.
      Through this program, students gain culinary experience as well as experience with research and presenting their work in a professional environment. Students spend weeks perfecting their recipes so that on competition day, they can recreate their dishes in person at various NASA centers across the country.
      This year, HUNCH Culinary student teams were tasked with the challenge of creating a savory breakfast dish that included a vegetable. The recipes had to fall between 150 and 350 calories, contain less than 12 grams of fat and 250 milligrams of sodium, have at least one gram of fiber, and “must process well for spaceflight and for use in microgravity” among several other requirements.
      An eager hand reaches for a small serving of eggs scrambled with vegetables and topped with seeds as a larger skillet of the savory breakfast dish sits to the left.NASA/Angelique Herring Several students described challenges around creating a recipe under these guidelines. Nyland Clay, a student at Landstown High School in Virginia Beach, explained his team’s problem solving around the minimal sodium guideline.
      “We were able to work around that by using different types of flavors in order to substitute for the extra sodium,” he said. “One of the ways we did this was with poblano peppers. When seared over a grill, they make a nice smoky flavor that doesn’t add any sodium whatsoever.”
      Nyland’s team additionally chose to use ground turkey in their sweet potato hash recipe instead of ground beef to avoid unnecessary fat.
      Travis Walker, culinary instructor at Phoebus High School in Hampton and former executive catering chef manager for the NASA Langley Exchange, spoke highly of his students as his reason for teaching.
      “The most rewarding part is just watching the growth of the kids,” he said. “From the day you get them and they can’t boil water, to the time they get here and they’re in these competitions and excelling — that’s the most rewarding part.”
      The student groups with the highest scores will be invited to Johnson Space Center in Houston for a final competition where their dishes will be judged by Johnson Food Lab personnel, industry professionals, the ISS program office, and astronauts. The criteria are quality, taste, and the students’ work on the research paper and presentation video. The winning entree will be processed by the Johnson Space Center Food Lab and sent up to the station for the astronauts to enjoy.
