TO 19C - Masten Mission 1

NSSDCA ID: XL1-LANDR
COSPAR ID: 

Description

The Xelene lander mission (TO 19C, or Masten Mission 1) is designed to bring eight payloads to the lunar surface in 2023 and operate them for at least 12 days. The lander mission was selected through NASA's Commercial Lunar Payload Services (CLPS) initiative, in which NASA contracts with a commercial partner, in this case Masten Space Systems, that provides the launch and lander.

The Xelene lunar lander, in the XL-1 configuration, has a dry mass of 675 kg and carries about 2000 kg of propellant. It has 6 main engines and 12 auxiliary thrusters. The has eight payloads, comprising nine science and technology instruments. The payloads are the Lunar Compact Infrared imaging System (L-CIRiS), the Linear Energy Transfer Spectrometer (LETS), the Heimdall Camera, the Mass Spectrometer observing Lunar operations (MSoLo), the Near-Infrared Volatile Spectrometer System (NIRVSS), the Laser Retroreflector Array (LRA), the Sample Acquisition, Morphology Filtering, and Probing of Lunar Regolith (SAMPLR) robotic arm, and the MoonRanger micro rover. Commercial payloads may also be added.

The lander will launch from Cape Canaveral on a SpaceX booster sometime in 2023 and go into lunar orbit. It will then descend to land at Haworth crater near the south pole, operating for about 12 days before lunar nightfall. Objectives of the mission include assessing the composition of the lunar surface, evaluating the radiation environment, and testing precision landing technologies.
