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.

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.

KENNEDY SPACE CENTER, Fla. -- Space Shuttle Discovery makes the turn toward Launch Pad 39B on its trek atop the mobile launcher platform and crawler transporter. Once at the pad, the orbiter, external tank and solid rocket boosters will undergo final preparations for the STS-103 launch targeted for Dec. 6, 1999, at 2:37 a.m. EST. The mission is a "call-up" due to the need to replace and repair portions of the Hubble Space Telescope. Although Hubble is operating normally and conducting its scientific observations, only three of its six gyroscopes are working properly. Four EVA's are planned to make the necessary repairs and replacements on the telescope. The STS-103 crew members are Commander Curtis L. Brown Jr., Pilot Scott J. Kelly, Steven L. Smith, C. Michael Foale (Ph.D.), John M. Grunsfeld (Ph.D.), and Claude Nicollier of Switzerland and Jean-François Clervoy of France, both with the European Space Agency.

This is a radar image of the Mississippi River Delta where the river enters into the Gulf of Mexico along the coast of Louisiana. This multi-frequency image demonstrates the capability of the radar to distinguish different types of wetlands surfaces in river deltas. This image was acquired by the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the space shuttle Endeavour on October 2, 1995. The image is centered on latitude 29.3 degrees North latitude and 89.28 degrees West longitude. The area shown is approximately 63 kilometers by 43 kilometers (39 miles by 26 miles). North is towards the upper right of the image. As the river enters the Gulf of Mexico, it loses energy and dumps its load of sediment that it has carried on its journey through the mid-continent. This pile of sediment, or mud, accumulates over the years building up the delta front. As one part of the delta becomes clogged with sediment, the delta front will migrate in search of new areas to grow. The area shown on this image is the currently active delta front of the Mississippi. The migratory nature of the delta forms natural traps for oil and the numerous bright spots along the outside of the delta are drilling platforms. Most of the land in the image consists of mud flats and marsh lands. There is little human settlement in this area due to the instability of the sediments. The main shipping channel of the Mississippi River is the broad red stripe running northwest to southeast down the left side of the image. The bright spots within the channel are ships. The colors in the image are assigned to different frequencies and polarizations of the radar as follows: red is L-band vertically transmitted, vertically received; green is C-band vertically transmitted, vertically received; blue is X-band vertically transmitted, vertically received. http://photojournal.jpl.nasa.gov/catalog/PIA01784

Glenn Jr., a senator from Ohio and one of the original seven Project Mercury astronauts, suits up with the help of George Brittingham, of United Space Alliance, in the Operations and Checkout (O&C)Building prior to his trip to Launch Pad 39-B. Glenn and the rest of the STS-95 crew are at KSC to participate in the Terminal Countdown Demonstration Test (TCDT) which includes mission familiarization activities, emergency egress training, and a simulated main engine cutoff. The other crew members are Payload Specialist Chiaki Mukai (M.D., Ph.D.), representing the National Space Development Agency of Japan (NASDA), Pilot Steven W. Lindsey, Mission Specialist Scott E. Parazynski, Mission Specialist Stephen K. Robinson, Mission Specialist Pedro Duque of Spain, representing the European Space Agency (ESA), and Mission Commander Curtis L. Brown. The STS-95 mission, targeted for liftoff on Oct. 29, includes research payloads such as the Spartan solar-observing deployable spacecraft, the Hubble Space Telescope Orbital Systems Test Platform, the International Extreme Ultraviolet Hitchhiker, as well as the SPACEHAB single module with experiments on space flight and the aging process. Following the TCDT, the crew will be returning to Houston for final flight preparations

CAPE CANAVERAL, Fla. - Inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, ground support technicians help position a sprocket shaft assembly onto a cradle as an overhead crane lowers it down. The sprocket assembly was removed from the C truck of crawler-transporter 2, or CT-2. They will be placed into shipping cradles on pallets and positioned on a flatbed trailer. The assemblies will be sent to a vendor for inspections and refurbishment. Work continues in high bay 2 to upgrade CT-2. The modifications are designed to ensure CT-2’s ability to transport launch vehicles currently in development, such as the agency’s Space Launch System, to the launch pad. The Ground Systems Development and Operations Program office at Kennedy is overseeing the upgrades. For more than 45 years the crawler-transporters were used to transport the mobile launcher platform and the Apollo-Saturn V rockets and, later, space shuttles to Launch Pads 39A and B.

CAPE CANAVERAL, Fla. – Crawler-transporter 2, or CT-2, travels along the crawlerway toward the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. The Ground Systems Development and Operations Program completed a roller bearing assembly test on CT-2 truck sections A and C. The left- and right-hand steering was tested in both directions. The temperature of the roller assemblies was monitored and recorded as it traveled along the crawlerway. Engineers and technicians performed visual inspections of the roller bearing pumps, valves and lines to ensure that the grease injectors worked properly and provided the required flow of grease to the new roller assemblies. Work continues in high bay 2 to upgrade CT-2. The modifications are designed to ensure CT-2’s ability to transport launch vehicles currently in development, such as the agency’s Space Launch System, to the launch pad.

KENNEDY SPACE CENTER, Fla. -- Space Shuttle Discovery, atop the mobile launcher platform and crawler transporter, nears the top of Launch Pad 39B after the trekfrom the Vehicle Assembly Building. At left are the Rotating Service Structure and the Fixed Service Structure, which will enable final preparations of the orbiter, external tank and solid rocket boosters for the STS-103 launch targeted for Dec. 6, 1999, at 2:37 a.m. EST. The mission is a "call-up" due to the need to replace and repair portions of the Hubble Space Telescope. Although Hubble is operating normally and conducting its scientific observations, only three of its six gyroscopes are working properly. Four EVA's are planned to make the necessary repairs and replacements on the telescope. The STS-103 crew members are Commander Curtis L. Brown Jr., Pilot Scott J. Kelly, Steven L. Smith, C. Michael Foale (Ph.D.), John M. Grunsfeld (Ph.D.), and Claude Nicollier of Switzerland and Jean-François Clervoy of France, both with the European Space Agency
