NASA Artemis V Moon Rocket Engine Test: Preparing for Crewed Missions

NASA Artemis V Moon Rocket Engine Test: Preparing for Crewed Missions

NASA conducted a long duration hot fire of an RS-25 certification engine March 21, 2023, continuing a key series of testing to support future Space Launch System (SLS) missions to deep space as part of Artemis missions as the agency continues to inspire the world through discovery.

Operators fired the certification engine for 10 minutes (600 seconds), longer than the 500 seconds engines must fire during an actual mission, on the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. Operators also fired the engine up to 113% power level, exceeding the 111% level needed during SLS launch. Hot fires of longer duration and higher power level allow operators to test the limits of engine performance and provide a margin of safety for flight operations. The March 21 hot fire was the fourth test in a series that began in early February to certify production of new RS-25 engines by lead contractor Aerojet Rocketdyne. The company is using advanced manufacturing techniques, such as 3D printing, to reduce the cost and time needed to build new engines for use on missions beginning with Artemis V. Four RS-25 engines help power SLS at launch, including on its Artemis missions to the Moon.

Through Artemis, NASA is returning humans, including the first woman and the first person of color, to the Moon to explore the lunar surface and prepare for flights to Mars. SLS is the only rocket capable of sending the agency’s Orion spacecraft, astronauts, and supplies to the Moon in a single mission.

Globular Star Cluster Messier 19 | Hubble

Globular Star Cluster Messier 19 | Hubble

This image of Messier 19 (M19) includes Hubble observations taken in ultraviolet, visible, and near-infrared wavelengths of light. A small gap in Hubble data (horizontal line at center right) is instead filled in with observations from the ground-based Victor M. Blanco 4-meter Telescope. The Hubble proposal associated with this image sought to investigate M19’s formation and the ratios of different populations of stars within the cluster.

M19 was discovered by Charles Messier in 1764. The cluster is located 28,500 light-years from Earth in the constellation Ophiuchus and is most easily observed during July. It has an apparent magnitude of 7.7 and can be spotted through a pair of binoculars, though it will only appear as a faint patch of light. Large telescopes will resolve M19’s individual stars.

Image Description: "The field is filled with orange, red, yellow, blue, and white stars. They appear as a spherical, dense mass that tapers out toward the edges of the image on a black background."

The stars in globular clusters orbit about a common center of gravity, so these clusters are usually spherical. Some globular clusters, like M19, have a slightly elongated shape. This cluster is only 6,500 light-years away from the center of our Milky Way galaxy, so the gravity and tidal forces from the massive galactic center could be causing M19 to stretch out.

NASA DART Spacecraft Asteroid Collision: Light Polarization Changes | ESO

NASA DART Spacecraft Asteroid Collision: Light Polarization Changes | ESO

This animation shows how the polarization of sunlight reflected by the Dimorphos asteroid changed after the impact of NASA’s DART spacecraft. At the beginning of the video, unpolarized sunlight—represented by wiggly blue lines oscillating in random directions—is reflected off the surface of the asteroid. In so doing it becomes polarized, the reflected waves now oscillating along a preferred direction. The indicator on the lower right shows the degree of polarization of the reflected sunlight.

The DART impact ejected a cloud of debris, and after the collision the amount of polarization dropped, as seen with the FORS2 instrument on European Southern Observatory’s Very Large Telescope. This drop in polarization could be due to the exposure of more pristine material from the interior of Dimorphos, or the ejection of small particles produced during the impact.

NASA DART Spacecraft Impact: Cloud of Debris at Asteroid Dimorphos

NASA DART Spacecraft Impact: Cloud of Debris at Asteroid Dimorphos

This image shows a total of 16 small images in a four by four grid, each taken on a different date. At the center of each image is a light blue fuzzy dot over a black background. In the first image the dot is surrounded by a diffuse halo, which morphs into different structures before eventually becoming a long tail pointing towards the right in the last image.

This series of images, taken with the MUSE instrument on ESO’s Very Large Telescope, shows the evolution of the cloud of debris that was ejected when NASA’s DART spacecraft collided with the asteroid Dimorphos.

The first image was taken on September 26, 2022, just before the impact, and the last one was taken almost one month later on October 25, 2022. Over this period several structures developed: clumps, spirals, and a long tail of dust pushed away by the Sun’s radiation. The white arrow in each panel marks the direction of the Sun.

Dimorphos orbits a larger asteroid called Didymos. The white horizontal bar corresponds to 500 kilometers, but the asteroids are only 1 kilometer apart, so they cannot be discerned in these images.

The background streaks seen here are due to the apparent movement of the background stars during the observations while the telescope was tracking the asteroid pair.

NASA Connects All Major Structures of Artemis II Moon Rocket Core Stage

NASA Connects All Major Structures of Artemis II Moon Rocket Core Stage


Teams at NASA’s Michoud Assembly Facility in New Orleans have fully integrated all five major structures of the Space Launch System (SLS) rocket’s core stage for Artemis II, the first crewed Artemis mission that will send four astronauts around the Moon and return them home. Technicians joined the engine section to the rest of the rocket stage March 17. Next, teams will integrate the four RS-25 engines to the engine section to complete the stage.

Located at the bottom of the 212-foot-tall core stage, the engine section is the most complex and intricate part of the rocket stage, helping to power Artemis missions to the Moon. In addition to its miles of cabling and hundreds of sensors, the engine section is a crucial attachment point for the RS-25 engines and two solid rocket boosters that produce a combined 8.8 million pounds of thrust at liftoff. It houses the engines and includes vital systems for mounting, controlling, and delivering fuel from the propellant tanks to the engines.

The core stage for Artemis II is built, outfitted, and assembled at Michoud. Through Artemis missions, NASA will land the first woman and the first person of color on the surface of the Moon, paving the way for a long-term lunar presence and serving as a steppingstone for astronauts on the way to Mars.

L.A. Youth Robotics Competition Leaves Student Teams Energized | NASA/JPL

L.A. Youth Robotics Competition Leaves Student Teams Energized | NASA/JPL

In a blur of motion, wheeled robots race across the “playing field” at the FIRST Robotics Competition Los Angeles Regional at the Da Vinci Schools campus in El Segundo.

Students from Da Vinci Schools Team 4201 (“Vitruvian Bots”) react in the stands during the 2023 FIRST Robotics Competition Los Angeles Regional.

Part of the winning alliance, JPL-sponsored Team 702 (“Bagel Bytes”) from Culver City High School gathers beside their banner and a mascot in a bagel costume at the 2023 FIRST Robotics Competition Los Angeles Regional.

Supported by volunteers from NASA's Jet Propulsion Laboratory (JPL) and the aerospace industry, the annual regional FIRST Robotics event makes an impact on young competitors and adult mentors alike.

After two days of fast-paced competition complete with team uniforms, cheerleaders, pounding music, and blaring horns, multiple teams of high schoolers came out victorious at the 23rd annual FIRST Robotics Competition Los Angeles Regional over the weekend. Next, they’ll be headed to an international championship tournament where their 125-pound inventions will compete for robotics glory.

NASA’s Jet Propulsion Laboratory sponsored several of the 44 competing teams and supported the event, held at the Da Vinci Schools campus in El Segundo, by coordinating about 100 volunteers. “It’s always gratifying to see these kids compete with such determination and passion, but it’s also wonderful to witness the joy they bring to the adults who come together for this event,” said Kim Lievense, who manages JPL’s Public Services Office and coordinated volunteers at the competition.

Energy and Community

The event is one of many taking place across the country under the umbrella of FIRST (For Inspiration and Recognition of Science and Technology). The nonprofit organization pairs students with STEM professionals for hands-on engineering experience and practice with problem-solving, team building, fundraising, and promotion, among other skills. Teams in the FIRST Robotics Competition receive technical specifications and game rules in January and have just weeks to design, build, and test their wheeled robots.

This year’s game, dubbed “Charged Up,” is themed around the future of sustainable energy. Two alliances of three teams compete on a “playing field” that’s about 26 by 54 feet. In each 2 ½-minute round, the teams’ robots must retrieve rubber cones and inflatable cubes that represent electrical power from “substations” and place them into a “grid.” Robots also race to roll up onto a wobbling “charge station” for extra points.

Students put in long hours preparing their robots. It all paid off in the case of Brianna Adewinmbi, a junior at the California Academy of Mathematics and Science in Carson. Her Team 687 (aka the “Nerd Herd”) came out on top, and she was one of two students selected as a finalist for the nationwide FIRST Dean’s List Award (inventor Dean Kamen founded FIRST) recognizing student leadership and dedication. Wearing a colorful propeller hat and fielding high-fives from fellow students, she said the team had been working after school till 10 p.m. for many days.

“It’s insane. I just keep thinking, It was all worth it, all the time that we spent,” Adewinmbi said.

Adewinmbi’s team will be joined at the FIRST Championship in Houston next month by the two other California teams from the winning alliance: Team 5199 (“Robot Dolphins From Outer Space”) from Dana Point and and Team 702 (“Bagel Bytes”) from Culver City. Team 6833 (“Phoenix Robotics”) from Arizona, which had subbed in for the Culver City team to play in the winning alliance, is on the priority waitlist to attend. Two award-winners, Team 5089 (“Robo-Nerds”) from Benjamin Franklin Senior High School in Los Angeles and Team 4201 (“Vitruvian Bots”) from Da Vinci Schools, will also head to Houston.

Volunteering Brings Rewards

For about two decades, NASA’s Robotics Alliance Project has supported youth robotics teams through agency centers across the country and at JPL, aiming to inspire students to pursue careers in aerospace while helping them build the skills they’ll need to succeed.

“We all do it for the same reason: It’s really to help get kids inspired in science, engineering, and technology,” said JPL’s Dave Brinza, assistant mission assurance manager for NASA’s Europa Clipper mission. Brinza started mentoring Team 980 (“ThunderBots”), now at Burbank High School, in 2003. “We often say the real trophies aren’t the blue banners and the things you put on a shelf, it’s the kids who go on and have successful careers.”

For Julie Townsend, a robotics systems engineer who is JPL’s point of contact for the NASA Robotics Alliance Project, it’s been a way to draw young women into a field in which they’re underrepresented. For nearly 20 years, she has coached Southern California Girl Scout teams in FIRST Tech Challenge, which is like a smaller-scale version of FIRST Robotics Competition. At the Los Angeles Regional event, she volunteered as a judge.

“I have had parents coming up to me in tears, thanking me for what I had done for their daughters, who had changed the course of their lives,” Townsend said. “It’s so unusual to have such a safe environment to learn these technical skills and develop your own power with no judgment and no social strings attached.”

2022 Atlantic Hurricane Season: 8 Major Storms | NOAA GOES East Satellite

2022 Atlantic Hurricane Season: 8 Major Storms | NOAA GOES East Satellite

The 2022 Atlantic hurricane season officially concluded on Nov. 30, 2022. 

It was a fairly average hurricane season with 14 named storms, eight of which strengthened into hurricanes. Two of these became major hurricanes (category 3 or higher on the Saffir–Simpson Hurricane Wind Scale). Despite this, it became one of the costliest Atlantic hurricane seasons on record, mostly due to Hurricane Ian. 

Additionally, it was the first season since 1997 in which no tropical cyclones formed in August, and the first season on record to do so during a La Niña year. 

The GOES East (GOES-16) satellite recorded this imagery of the entire Atlantic basin from its operational location of 75.2 degrees west longitude. This allows us to show storms as they form off the coast of Africa and then enter the Atlantic.

Planet Saturn & Titan Moon: Solar System Giants | NASA Cassini Mission

Planet Saturn & Titan Moon: Solar System Giants | NASA Cassini Mission

Titan, Saturn’s largest moon, looks quite small in comparison to the giant planet behind it in this natural color view from the Cassini-Huygens spacecraft. This image from Aug. 29, 2012, also shows seasonal changes occurring on Saturn; as spring comes to the northern Saturnian hemisphere, the azure blue seen fades, while winter in the south adds a bluish hue. This phenomenon is likely due to shifts in the intensity of ultraviolet light and the haze it produces.

The Cassini spacecraft ended its mission on Sept. 15, 2017. Cassini's end involved a series of close Saturn passes, approaching within the rings, then an entry into Saturn's atmosphere to destroy the spacecraft. This method was chosen because it is necessary to ensure protection and prevent biological contamination to any of the moons of Saturn thought to offer potential habitability.

For more information about the Cassini-Huygens mission visit: https://saturn.jpl.nasa.gov and www.nasa.gov/cassini

The Cassini-Huygens mission was a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, California, managed the mission for NASA's Science Mission Directorate, Washington, D.C.

NASA's Parker Solar Probe Observes Sun Alongside Dozens of Observatories

NASA’s Parker Solar Probe completed its 15th close approach to the Sun on March 17, coming within 5.3 million miles of the scorching solar surface. The geometry of Parker’s latest orbit also placed it in direct view of Earth and several other Sun-observing spacecraft during its close encounter, providing unique scientific opportunities for collaborative observations from the ground and space. 

Parker Solar Probe Mission Information:

https://jhuapl.link/psp-wzk

Parker Solar Probe is humanity’s first mission to the sun. It orbits directly through the solar atmosphere–the corona–closer to the surface than any human-made object has ever gone. While facing brutal heat and radiation, the mission will reveal fundamental science behind what drives the solar wind, the constant outpouring of material from the sun that shapes planetary atmospheres and affects space weather near Earth.

Parker Solar Probe is part of NASA’s Living With a Star Program to explore aspects of the connected sun-Earth system that directly affect life and society.

Almost Touching: The Milky Way & The Swedish-ESO Telescope


Night image of the Swedish-ESO Telescope with an overall grey and dark blue color. The telescope is a big antenna seen sideways, taking up most of the left part of the image. To the right of the telescope the Milky Way dominates the sky and contains dark and bright areas. The Chilean mountains shape the horizon above the ground in the lower part of the image. This Picture of the Week shows a beautiful meeting between the Swedish–ESO Submillimetre Telescope (SEST) and the Milky Way, apparently almost touching each other. This shot was taken at the European Southern Observatory’s La Silla Observatory, located on the outskirts of the Chilean Atacama Desert, at an altitude of 2400 meters.

Light and darkness shape the Milky Way as it stretches across the night sky. The dark patches are dust clouds blocking the light behind them, coming from millions of stars in the central region of our galaxy.

Portrait of a Galactic Jellyfish: Galaxy JW100 | Hubble

Portrait of a Galactic Jellyfish: Galaxy JW100 | Hubble


The galaxy JW100 features prominently in this image from the NASA/European Space Agency Hubble Space Telescope, with streams of star-forming gas dripping from the disc of the galaxy like streaks of fresh paint. These tendrils of bright gas are formed by a process called ram pressure stripping, and their resemblance to dangling tentacles has led astronomers to refer to JW100 as a ‘jellyfish’ galaxy. It is located in the constellation Pegasus, over 800 million light-years away.

Image Description: A thin spiral galaxy is seen edge-on in the lower right. Its bulge and arms are very bright, mixing reddish and bluish light. Patchy blue trails extend below it, resembling tentacles, made from star-forming regions. Six small, reddish elliptical galaxies are scattered around. A very large elliptical galaxy with two cores sits by the top of the frame.

Ram pressure stripping occurs when galaxies encounter the diffuse gas that pervades galaxy clusters. As galaxies plough through this tenuous gas it acts like a headwind, stripping gas and dust from the galaxy and creating the trailing streamers that prominently adorn JW100. The bright elliptical patches in the image are other galaxies in the cluster that hosts JW100.

As well as JW100’s bright tendrils, this image also contains a remarkably bright area of diffuse light towards the top of this image which contains two bright blotches at its core. This is the core of IC 5338, the brightest galaxy in the galaxy cluster, known as a cD galaxy. It’s not unusual for cD galaxies to exhibit multiple nuclei, as they are thought to grow by consuming smaller galaxies, the nuclei of which can take a long time to be absorbed. The bright points of light studding its outer fringes are a rich population of globular clusters. 

This observation took advantage of the capabilities of Hubble’s Wide Field Camera 3, and is part of a sequence of observations designed to explore star formation in the tendrils of jellyfish galaxies. These tendrils represent star formation under extreme conditions, and could help astronomers understand the process of star formation elsewhere in the universe.
