Booster stacking for NASA’s Space Launch System (SLS) rocket is continuing at NASA’s Kennedy Space Center. The second of five segments for the SLS rocket boosters have been placed on the mobile launcher in preparation for the launch of Artemis I later this year. This marks four out of 10 solid rocket booster segments being lifted via crane and placed on the launcher, the structure used to process, assemble, and launch SLS. The twin boosters will power the first flight of SLS, the agency’s new deep space rocket for Artemis I. This uncrewed flight will test the SLS and Orion spacecraft as an integrated system ahead of crewed flights to the Moon as part of the Artemis program.

Artemis Instrument Ready for Extreme Moon Temperatures
A versatile instrument designed to help analyze the chemical makeup of lunar landing sites and study water on the Moon as part of the Artemis program has completed an important step in its final assembly.
Teams working on the Mass Spectrometer Observing Lunar Operations, or MSolo, at NASA’s Kennedy Space Center in Florida installed the radiator – a critical component that will keep the instrument’s temperature stable in the extreme heat and cold it will encounter on the Moon.
MSolo is a commercial off-the-shelf mass spectrometer modified to work in space. NASA will use MSolo to identify molecules on the surface of the Moon. Multiple MSolo instruments are destined for the Moon via the help of NASA’s commercial partners, landing scientific instruments and technology demonstrations on the lunar surface as part of the Commercial Lunar Payload Services (CLPS) initiative.
NASA has scheduled MSolo instruments to launch on future robotic missions starting in 2021 at Lacus Mortis, a large crater on the near side of the Moon. MSolo is a key component of the Polar Resources Ice Mining Experiment, or PRIME-1, instrument suite that will use a drill to harvest ice just below the lunar surface in 2022. Later, the technology will be one of three instruments on board NASA’s water-hunting Volatiles Investigating Polar Exploration Rover, VIPER, scheduled to launch to the Moon’s South Pole in late 2023.
On VIPER, the MSolo instrument will help evaluate subsurface soil cuttings brought up by a 3-foot drill in search of water ice and other volatiles that future missions could use as resources. The mission will create the most detailed view of the Moon’s water to date – helping to pave the way for the lunar surface missions with crew beginning in 2024.
Orion Spreads its Wings
Inside the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida, technicians have extended one of the Artemis I solar array wings on Sept. 10, 2020. Prior to installation on the Orion spacecraft, the team performed an inspection to confirm proper extension and to ensure all of the mechanisms functioned as expected. The pictured solar array is one of four panels that will generate 11 kilowatts of power and span about 63 feet. The array is a component of Orion’s service module, which is provided by the European Space Agency and built by Airbus Defence and Space to supply Orion’s power, propulsion, air and water.
The first in a series of increasingly complex missions, Artemis I will test the Orion spacecraft and Space Launch System as an integrated system ahead of crewed flights to the Moon. Under the Artemis program, NASA will land the first woman and the next man on the Moon in 2024.
