EUS panel test weld at the VXC in Building 115 at the Michoud Assembly Facility on Tuesday, February 9, 2021. Technicians are manufacturing and testing the first in a series of initial weld confidence articles for the Exploration Upper Stage (EUS) for future flights of NASA’s Space Launch System (SLS) rocket at the agency’s Michoud Assembly Facility in New Orleans. The Exploration Upper Stage will be used on the second configuration of the SLS rocket, known as Block 1B, and will provide in-space propulsion to send astronauts in NASA’s Orion spacecraft and heavy cargo on a precise trajectory to the Moon. The Exploration Upper Stage weld confidence panels are first produced in the Vertical Weld Center at Michoud, then small sections of the panels are removed for mechanical testing and analysis in another area of the factory. Teams use weld confidence articles to verify welding procedures, interfaces between the tooling and hardware, and the structural integrity of the welds. Testing of the EUS weld confidence articles will help engineers and technicians validate welding parameters for manufacturing EUS hardware. The first three SLS flights of NASA’s Artemis program will use an interim cryogenic propulsion stage with one RL10 engine to send Orion to the Moon. The SLS Exploration Upper Stage for flights beyond Artemis III has larger propellant tanks and four RL10 engines. The evolution of the rocket to SLS Block 1B configuration with EUS enables SLS to launch 40% more cargo to the Moon along with the crew. Manufacturing the Exploration Upper Stage is a collaborative effort between NASA and Boeing, the lead contractor for EUS and the SLS core stage. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission. The SLS rocket, NASA’s Orion spacecraft, Gateway, and human landing system are part of NASA’s backbone for deep space exploration. Under the Artemis program, NASA is working to land the first woman and the next man on the Moon to pave the way for sustainable exploration at the Moon and future missions to Mars. (NASA)

Move crews at NASA’s Michoud Assembly Facility in New Orleans guide the Inter-Stage Simulator (ISS) to the Michoud deep water port on Monday, Sept. 19 in preparation for transportation by barge to the agency’s Stennis Space Center near Bay St. Louis, Mississippi. Once it arrives at Stennis, the simulator will be lifted into the B2 Test Stand, where it holds the Exploration Upper Stage (EUS) in place and acts as a thrust takeout. ISS protects the lower portion of the EUS from environmental elements during its Green Run tests. The term “green” refers to the new hardware, and “run” refers to operation all the components together for the first time. During tanking and launch for its future mission, the lower portion is shrouded in a flight interstage. EUS is part of the SLS Block 1B configuration. The more powerful configuration of the SLS rocket will provide in-space propulsion to send astronauts in NASA’s Orion spacecraft and 40% more cargo mass on a precise trajectory to the Moon. Through the Artemis missions, NASA will land the first woman and the first person of color on the Moon to pave the way for a sustainable presence on the Moon and future missions beyond.

Once it arrives at Stennis, the simulator will be lifted into the B2 Test Stand, where it holds the Exploration Upper Stage (EUS) in place and acts as a thrust takeout. ISS protects the lower portion of the EUS from environmental elements during its Green Run tests. The term “green” refers to the new hardware, and “run” refers to operation all the components together for the first time. During tanking and launch for its future mission, the lower portion is shrouded in a flight interstage. EUS is part of the SLS Block 1B configuration. The more powerful configuration of the SLS rocket will provide in-space propulsion to send astronauts in NASA’s Orion spacecraft and 40% more cargo mass on a precise trajectory to the Moon.

A pair of umbilical support structures needed for future testing of NASA’s exploration upper stage (EUS) were installed in the B-2 position of the Thad Cochran Test Stand on Oct. 30-31 at NASA’s Stennis Space Center. The support structures arrived from NASA’s Michoud Assembly Facility in New Orleans via the unique NASA Stennis seven-and-a-half-mile canal system in 2023. Since then, crews have prepared the structures that will align with the EUS unit for installation. In addition to helping secure the unit in place during hot fire testing, the umbilical support structures are where the command, control, and data electrical connections are mated to connect the ground systems to the vehicle systems, as well as most the commodity connections such as liquid hydrogen, liquid oxygen, hydrogen vent, helium bottle fill pressure, and purges. Prior to its initial flight, the EUS unit will undergo a series of so-called Green Run tests at NASA Stennis to ensure all systems are ready to go. The test series will culminate with a hot fire of the stage’s four RL10 engines, made by Aerojet Rocketdyne, an L3Harris Technologies company and lead SLS engines contractor. The new upper stage will enable NASA to carry larger payloads on Artemis missions to the Moon and beyond.

The Pearl River County Leadership Class stands in front of the Thad Cochran Test Stand during a NASA Stennis site tour on Jan. 18. The group learned about the RS-25 engine certification test series underway for future flights of NASA’s SLS (Space Launch System) rocket and preparations for Green Run testing at the Thad Cochran Test Stand (B-2) for NASA’s Exploration Upper Stage (EUS) in support of the Artemis program. EUS is expected to fly on the Artemis IV mission. Prior to that time, it will undergo a series of integrated systems tests to demonstrate it is ready to fly. Through Artemis, NASA will send the first woman and first person of color to the Moon. The agency will use what is learned on and around the Moon to take the next giant leap – sending astronauts to Mars.

These images show technicians at NASA’s Michoud Assembly Facility in New Orleans removing a weld-confidence article from a robotic welding tool in December 2023. This article features pieces of a liquid hydrogen tank dome that were welded as a test to make sure the dome used for flight will be welded correctly. The dome will be part of the new, four-engine EUS (exploration upper stage) for NASA’s SLS (Space Launch System) rocket. EUS will be used for the Artemis IV lunar mission, replacing the single-engine interim cryogenic propulsion stage (ICPS) used for the first three Artemis missions. The evolved in-space stage will use a combination of liquid oxygen and liquid hydrogen propellants to help power the engines to send large cargo and crew inside NASA’s Orion spacecraft to the Moon. The weld-confidence article pictured here will not be used for flight but is instead helping teams prepare and certify the procedures needed to manufacture flight hardware. NASA is working to land the first woman and person of color on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

Technicians at NASA’s Michoud Assembly Facility in New Orleans on Feb. 22 prepare elements that will form part of the midbody for the future exploration upper stage for the SLS (Space Launch System) rocket. The midbody struts, or V-struts, will create the midbody’s cage-like outer structure to connect the upper stage’s larger liquid hydrogen tank to its smaller liquid oxygen tank. Manufacturing flight and test hardware for the future SLS upper stage is a collaborative effort between NASA and Boeing, the lead contractor for EUS and the SLS core stage. Beginning with Artemis IV, SLS will evolve to its more powerful Block 1B configuration with the advanced exploration upper stage that gives the rocket the capability to launch 40% more to the Moon along with Artemis astronauts inside NASA’s Orion spacecraft. The evolved in-space stage for SLS will use a combination of liquid oxygen and liquid hydrogen propellants to help power the engines to send large cargo and crew inside Orion to the Moon.

These photos and videos show how crews at NASA’s Marshall Space Flight Center in Huntsville, Alabama, moved and installed the payload adapter that will be used in the Block 1B configuration of the SLS (Space Launch System) rocket from Building 4708, where it was manufactured, into Structural Test Stand 4697 at NASA’s Marshall Space Flight Center on March 13. Teams at Marshall will begin structural testing the engineering development unit of the payload adapter – an exact replica of the flight version of the hardware – this spring. The cone-shaped payload adapter is about 8.5 feet tall and features two metal rings and eight composite panels. The adapter, which will debut on NASA’s Artemis IV mission, is an evolution from the Orion stage adapter used in the Block 1 configuration of the first three Artemis missions. It will be housed inside the universal stage adapter atop the rocket’s more powerful in-space stage, called the exploration upper stage. The payload adapter, like the launch vehicle stage adapter and the Orion stage adapter, is fully manufactured and tested at Marshall, which manages the SLS Program. NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft and Gateway in orbit around the Moon and commercial human landing systems, next-generational spacesuits, and rovers on the lunar surface. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

ISS028-E-024146 (2 Aug. 2011) --- Kaliningrad and Baltic Sea, Russia are featured in this image photographed by an Expedition 28 crew member on the International Space Station. This striking photograph reveals detail of the two great lagoons to the north and south of Kaliningrad, each protected from the open waters of the Baltic Sea by the thin perfect curves of current-generated sand spits. A broad arm of agricultural country separates the freshwater lagoons?known as Kurshsky Bay (or the Curonian Lagoon further north in Lithuania, just outside the top of the image) and the Vistula Lagoon. From the crew member perspective in low Earth orbit, land surfaces usually appear brighter than water, which normally appears darker and often black. Reflected sunlight, or sunglint, inverts this pattern. The reflected light in this image is a pink or coppery hue, indicating the likely existence of smog in the air since smog particles enhance the red part of the light spectrum. Camera settings used to acquire sunglint images result in high contrast that reveals excellent detail of coastlines and surface features of waterbodies, but masks land surface detail. The thin, 50 kilometer-long barge canal leading from the Baltic Sea to Kaliningrad is visible but the great port of Kaliningrad itself is not. Other human patterns on this intensively developed landscape such as towns, highways and farm boundaries are likewise masked in the image. The area has a long human history. The growth of the Vistula spit finally cut off the north Polish city of Elblag (just outside the bottom of the image) from the Baltic Sea in the 13th century. To reconnect Elblag directly with the Baltic Sea, the EU is considering funding the digging of another canal through the spit at lower right, despite ecological concerns. Kaliningrad was heavily damaged during WWII and then annexed by Russia and cleared of its German population. As the only Russian port on the Baltic Sea to be ice-free year-round, Kaliningrad then gained importance strategically as home of the Baltic Fleet.

This illustration shows the front of the Sentinel-6 Michael Freilich spacecraft in orbit above Earth with its deployable solar panels extended. As the world's latest ocean-monitoring satellite, it is launching on Nov. 10, 2020, to collect the most accurate data yet on global sea level and how our oceans are rising in response to climate change. The mission will also collect precise data of atmospheric temperature and humidity that will help improve weather forecasts and climate models. The conelike instrument on the bottom (Earth-facing side) of the spacecraft is the satellite's Poseidon-4 radar altimeter. The disklike instrument at the front of the spacecraft is the Advanced Microwave Radiometer (AMR-C). Both instruments will be used together to measure ocean surface height. The gray rectangle with six cones attached at the front-left of the spacecraft is part of the Global Navigation Satellite System - Radio Occultation (GNSS-RO) instrument. Sentinel-6 Michael Freilich extends the near-30-year record of satellite measurements of sea level initiated by the U.S.-European TOPEX/Poseidon mission in 1992 and that continued with the Jason-1, 2, and 3 series of sea level observation satellites. Launched in 2016, Jason-3 is currently providing data. The satellite is named after Dr. Michael Freilich, the former director of NASA's Earth Science Division and an instrumental figure in advancing ocean observations from space.

The ocean-monitoring satellite will undergo prelaunch tests before its scheduled launch on Nov. 10, 2020. Sentinel-6 Michael Freilich will begin a five-and-a-half-year mission to collect sea surface height measurements down to the centimeter for 90% of the world's oceans. The satellite is named after Dr. Michael Freilich, the former director of NASA's Earth Science Division and an instrumental figure in advancing ocean observations from space. Sentinel-6 Michael Freilich is one of two identical spacecraft that compose the Sentinel-6/Jason-CS (Continuity of Service) mission developed in partnership with ESA (the European Space Agency). ESA is developing the new Sentinel family of missions to support the operational needs of the European Union's Copernicus program, the EU's Earth observation program managed by the European Commission. The spacecraft's twin, Sentinel-6B, will launch in 2025. Sentinel-6/Jason-CS is being jointly developed by ESA, the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), NASA, and the National Oceanic and Atmospheric Administration, with funding support from the European Commission and technical support from France's National Centre for Space Studies (CNES). JPL, a division of Caltech in Pasadena, is contributing three science instruments for each Sentinel-6 satellite: the Advanced Microwave Radiometer, the Global Navigation Satellite System - Radio Occultation, and the Laser Retroreflector Array. NASA is also contributing launch services, ground systems supporting operation of the NASA science instruments, the science data processors for two of these instruments, and support for the international Ocean Surface Topography Science Team. https://photojournal.jpl.nasa.gov/catalog/PIA24104

This illustration shows the rear of the Sentinel-6 Michael Freilich spacecraft in orbit above Earth with its deployable solar panels extended. As the world's latest ocean-monitoring satellite, it is launching on Nov. 10, 2020, to collect the most accurate data yet on global sea level and how our oceans are rising in response to climate change. The mission will also collect precise data of atmospheric temperature and humidity that will help improve weather forecasts and climate models. The conelike instrument on the bottom (Earth-facing side) of the spacecraft is the satellite's Poseidon-4 radar altimeter. When used with the Advanced Microwave Radiometer (AMR-C) attached to the front of the spacecraft, both instruments will be used to make precise measurements of sea surface height. The gray rectangle with 12 cones attached at the rear-left of the spacecraft is part of the Global Navigation Satellite System - Radio Occultation (GNSS-RO) instrument. Sentinel-6 Michael Freilich extends the near-30-year record of satellite measurements of sea level initiated by the U.S.-European TOPEX/Poseidon mission in 1992 and that continued with the Jason-1, 2, and 3 series of sea level observation satellites. Launched in 2016, Jason-3 is currently providing data. The satellite is named after Dr. Michael Freilich, the former director of NASA's Earth Science Division and an instrumental figure in advancing ocean observations from space. Sentinel-6 Michael Freilich is one of two identical spacecraft that compose the Sentinel-6/Jason-CS (Continuity of Service) mission developed in partnership with ESA (the European Space Agency).
