Engineers conduct a mass properties test on the Mass Spectrometer Observing Lunar Operations (MSolo) instrument inside Kennedy Space Center’s Space Station Processing Facility in Florida on Nov. 22, 2022. Mass properties determines the mass and center of gravity of the flight unit. The lander uses this information, from all payloads, to improve stability and performance of the lander – and to a lesser degree, the stability and performance of the rocket. This marks the end of testing at Kennedy for the Polar Resources Ice Mining Experiment-1 (PRIME-1) MSolo instrument. It will soon be shipped to Intuitive Machines in Houston for integration on the NOVA-C landing platform. Launching in 2023, the PRIME-1 mission will be the first in-situ resource utilization demonstration on the Moon.

A team from Honeybee Robotics in Altadena, California participates in simulation training for the Polar Resources Ice Mining Experiment-1 (PRIME-1) on Thursday, Nov. 2, 2023, inside the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida. The purpose of the training is to get the integrated PRIME-1 team – engineers with PRIME-1’s MSOLO (Mass Spectrometer Observing Lunar Operations) and Honeybee Robotics’ TRIDENT (The Regolith and Ice Drill for Exploring New Terrain) drill – prepared to operate the instrument on the lunar surface. The team commanded the PRIME-1 hardware, located at Intuitive Machines in Houston, to operate MSOLO and TRIDENT. PRIME-1 is scheduled to launch through NASA’s CLPS (Commercial Lunar Payload Delivery Service) initiative and will be the first in-situ resource utilization demonstration on the Moon, with MSOLO and TRIDENT making up its two primary components. Through Artemis missions, CLPS deliveries will be used to perform science experiments, test technologies, and demonstrate capabilities to help NASA explore the Moon and prepare for human deep space exploration missions.

S66-30238 (1 April 1966) --- The National Aeronautics and Space Administration (NASA) has named these astronauts as the prime crew of the first manned Apollo Space Flight. Left to right, are Edward H. White II, command module pilot; Virgil I. Grissom, mission commander; and Roger B. Chaffee, lunar module pilot. On the second row are the Apollo 1 backup crew members, astronauts David R. Scott, James A. McDivitt and Russell L. Schweickart. EDITOR'S NOTE: Astronauts Grissom, White and Chaffee lost their lives in a Jan. 27, 1967 fire in the Apollo CM during testing at Cape Canaveral. McDivitt, Scott and Schweickart later served as crewmembers for the Apollo 9 Earth-orbital mission, which was one of the important stair-step missions leading up to the Apollo 11 manned lunar landing mission of July 1969.

S73-24303 (May 1973) --- These three astronauts have been named by the National Aeronautics and Space Administration as the prime crew of the first manned Skylab mission. They are, left to right, Joseph P. Kerwin, science pilot; Charles Conrad Jr., commander; and Paul J. Weitz, pilot. Skylab is a three-part program consisting of one 28-day and two 56-day manned visits spanning an eight-month period. One day prior to the launch of this crew, the unmanned Skylab space station cluster will be launched and placed in Earth orbit. The first manned mission will last up to 28 days. Photo credit: NASA

Workers at the Astrotech processing facility in Titusville prepared for a news media showing of the Geostationary Operational Environmental Satellite-1 (GOES-1). GOES-1 was the first in a new generation of weather satellites deployed above Earth. It was the first 3-axis, body-stabilized meteorological satellite to be used by the National Oceanic Atmospheric Administration (NOAA) and NASA. These features allowed GOES-1 to continuously monitor the Earth, rather than viewing it just five percent of the time as was the case with spin-stabilized meteorological satellites. GOES-1 also has independent imaging and sounding instruments which can operate simultaneously yet independently. As a result, observations provided by each instrument will not be interrupted. The imager produces visual and infrared images of the Earth's surface, oceans, cloud cover and severe storm development, while the prime sounding products include vertical temperature and moisture profiles, and layer mean moisture.
