Engineers and technicians from NASA's Jet Propulsion Laboratory work on the NASA-ISRO Synthetic Aperture Radar (NISAR) science instrument payload in a clean room at JPL on Feb. 3, 2023. The payload is scheduled to ship to India in March 2023. The NISAR mission – a joint effort between NASA and ISRO – will measure changes to Earth's land ice surfaces down to fractions of an inch. Data collected by this satellite will help researchers monitor a wide range of changes critical to life on Earth in unprecedented detail. This includes spotting warning signs of imminent volcanic eruptions, helping to monitor groundwater supplies, tracking the melt rate of ice sheets tied to sea level rise, and observing shifts in the distribution of vegetation around the world. The data will inform humanity's responses to urgent challenges posed by natural disasters and climate change, and help communities prepare for and manage hazards. There are two instruments on the satellite that will send and receive radar signals to and from Earth's surface to make the mission's measurements. An L-band synthetic aperture radar (SAR), which uses a signal wavelength of around 9 inches (24 centimeters), and an S-band SAR with a signal wavelength of nearly 5 inches (12 centimeters). Both will bounce their microwave signal off of the planet's surface and record how long it takes the signal to make one roundtrip, as well as the strength of that return signal. This enables the researchers to calculate the distance from the spacecraft to Earth's surface and thereby determine how the land or ice is changing. An antenna reflector nearly 40 feet (12 meters) in diameter, supported by a deployable boom, will focus the microwave signals sent and received by the SARs. JPL, which is managed for NASA by Caltech in Pasadena, leads the U.S. component of NISAR and is providing the mission's L-band SAR instrument. NASA is also providing the radar reflector antenna, the deployable boom, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder, and payload data subsystem. ISRO is providing the spacecraft bus, the S-band SAR, the launch vehicle, and associated launch services and satellite mission operations. https://photojournal.jpl.nasa.gov/catalog/PIA25771

Frank Fedor and a technician helper are attaching a half-scale version of an inflatable wing in a hangar at NASA Flight Research Center at Edwards, California. The Paresev in this configuration was called the 1-C and was expected to closely approximate the aerodynamic characteristics that would be encountered with the Gemini space capsule with a parawing extended. The whole wing was not inflatable; the three chambers that acted as spars and supported the wing inflated.

Researcher Bill Reiwaldt discusses the preparations for a test in the Altitude Wind Tunnel with technicians Jack Wagner and Dick Golladay at the National Advisory Committee for Aeronautics (NACA) Lewis Flight Propulsion Laboratory. Research engineers developed ideas for tests that were often in response to requests from the military or aircraft industry. Arrangements were made to obtain an engine for the study and to transport it to the Cleveland laboratory. The engine was brought into the facility’s shop area, where it was readied for investigation. It was common for several different engines to be worked on simultaneously in the shop. The researcher would discuss the engine and the test objectives with the Test Installation Division and the facility’s technicians. The operations team would handle the installation of the instrumentation and fitting the test into the facility’s schedule. Upon completion of the previous test, the engine was removed. The next engine was lifted by an overhead crane and transported from the shop to the test section. The engine was connected to the measurement devices and fuel and oil supply lines. Engines were tested over numerous runs under varying conditions and with variations on the configuration. The findings and test procedure were then described in research or technical memorandums and distributed to industry.

At Vandenberg Air Force Base in California, technicians prepare the AIM spacecraft for fairing installation. The fairing is a molded structure that fits around the spacecraft and forms an aerodynamically smooth nose cone, protecting the spacecraft during launch. Launch will be from a Pegasus XL rocket, carried and released by Orbital Sciences L-1011 jet aircraft. AIM, which stands for Aeronomy of Ice in the Mesosphere, is being prepared for integrated testing and a flight simulation. The AIM spacecraft will fly three instruments designed to study polar mesospheric clouds located at the edge of space, 50 miles above the Earth's surface in the coldest part of the planet's atmosphere. The mission's primary goal is to explain why these clouds form and what has caused them to become brighter and more numerous and appear at lower latitudes in recent years. AIM's results will provide the basis for the study of long-term variability in the mesospheric climate and its relationship to global climate change. Launch is scheduled for April 25.

An engineer and technician at the National Aeronautics and Space Administration (NASA) Lewis Research Center install the instrumentation on spherical fuel tanks for an investigation of the behavior of liquids in microgravity. Lewis researchers were undertaking a broad effort to study the heat transfer properties of high energy propellants such as liquid hydrogen in microgravity. In the center’s 2.2-Second Drop Tower they investigated the wetting characteristics of liquid and the liquid-vapor configurations, and predicted the equilibrium state in microgravity conditions. Lewis was also conducting a series microgravity investigations which launched 9-inch diameter spherical dewars, seen here, on an Aerobee sounding rocket. A camera inside the rocket filmed the liquid hydrogen’s behavior during its 4 to 7 minutes of freefall. The researchers concluded, however, that they needed to extend the weightlessness period to obtain better results. So they designed an experiment to be launched on an Atlas missile that would provide 21 minutes of weightlessness. The experiment was flight qualified at Lewis. The 36-percent full liquid hydrogen stainless steel dewar was launched on the Atlas on February 25, 1964. The instrumentation measured temperature, pressure, vacuum, and liquid level. Temperature instrumentation indicated wall drying during the freefall. The resultant pressure-rise characteristics were similar to those used for the normal-gravity test.

These photos show the launch vehicle stage adapter (LVSA) of NASA’s SLS (Space Launch System) rocket for Artemis III before technicians at NASA’s Marshall Space Flight Center in Huntsville, Alabama, applied the thermal protection system to it. Artemis III will land astronauts on the Moon to advance long-term lunar exploration and scientific discover and inspire the Artemis Generation. Teams at Marshall began applying the thermal protection system material in the spring of 2023. Unlike other parts of the SLS rocket, the thermal protection system material for the LVSA is applied entirely by hand using a spray gun. During application, the technicians use a thin measuring rod to gauge the proper thickness. Once the thermal protection system has cured, certain areas are sanded down to meet parameters. The entire process takes several months. The LVSA is fully manufactured at Marshall by NASA, lead contractor Teledyne Brown Engineering, and the Jacobs Space Group’s ESSCA contract. The LVSA for Artemis III is the last of its kind as future SLS rockets will transition to its next, more powerful Block 1B configuration beginning with Artemis IV. NASA is working to land the first woman and first 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 mission.

These photos show the launch vehicle stage adapter (LVSA) of NASA’s SLS (Space Launch System) rocket for Artemis III before technicians at NASA’s Marshall Space Flight Center in Huntsville, Alabama, applied the thermal protection system to it. Artemis III will land astronauts on the Moon to advance long-term lunar exploration and scientific discover and inspire the Artemis Generation. Teams at Marshall began applying the thermal protection system material in the spring of 2023. Unlike other parts of the SLS rocket, the thermal protection system material for the LVSA is applied entirely by hand using a spray gun. During application, the technicians use a thin measuring rod to gauge the proper thickness. Once the thermal protection system has cured, certain areas are sanded down to meet parameters. The entire process takes several months. The LVSA is fully manufactured at Marshall by NASA, lead contractor Teledyne Brown Engineering, and the Jacobs Space Group’s ESSCA contract. The LVSA for Artemis III is the last of its kind as future SLS rockets will transition to its next, more powerful Block 1B configuration beginning with Artemis IV. NASA is working to land the first woman and first person of color on the Moon under Artemis.

Flight Crew Systems Technicians Ray Smith and Raphael Rodriguez remove one of the Extravehicular Mobility Units, or EMUs, from the Space Shuttle Discovery after it's successful landing at NASA's Dryden Flight Research Center. The Space Shuttles receive post-flight servicing in the Mate-Demate Device (MDD) following landings at NASA's Dryden Flight Research Center, Edwards, California. The gantry-like MDD structure is used for servicing the shuttle orbiters in preparation for their ferry flight back to the Kennedy Space Center in Florida, including mounting the shuttle atop NASA's modified Boeing 747 Shuttle Carrier Aircraft. Space Shuttle Discovery landed safely at NASA's Dryden Flight Research Center at Edwards Air Force Base in California at 5:11:22 a.m. PDT, August 9, 2005, following the very successful 14-day STS-114 return to flight mission. During their two weeks in space, Commander Eileen Collins and her six crewmates tested out new safety procedures and delivered supplies and equipment the International Space Station. Discovery spent two weeks in space, where the crew demonstrated new methods to inspect and repair the Shuttle in orbit. The crew also delivered supplies, outfitted and performed maintenance on the International Space Station. A number of these tasks were conducted during three spacewalks. In an unprecedented event, spacewalkers were called upon to remove protruding gap fillers from the heat shield on Discovery's underbelly. In other spacewalk activities, astronauts installed an external platform onto the Station's Quest Airlock and replaced one of the orbital outpost's Control Moment Gyroscopes. Inside the Station, the STS-114 crew conducted joint operations with the Expedition 11 crew. They unloaded fresh supplies from the Shuttle and the Raffaello Multi-Purpose Logistics Module. Before Discovery undocked, the crews filled Raffeallo with unneeded items and returned to Shuttle payload bay. Discovery launched on July 26 and spent almost 14
