![]() This image travelled over SpaceWire twice: from the NAC to the mass memory and from the mass memory to the downlink communication system. ![]() The black lines radiating out from Intrepid and pointed to by arrows in other parts of this image are the footsteps of the Apollo 12 astronauts. The Apollo 12 (Intrepid) descent stage is clearly visible in the image as is the earlier Surveyor 3 spacecraft. It was launched in 2009 and is still in operation in. The Diviner Lunar Radiometer Experiment on NASA’s Lunar Reconnaissance Orbiter will be the first instrument to systematically map the global thermal state of the Moon and its diurnal and seasonal variability. The C&DH computer includes a 4-port SpaceWire router for handling the SpaceWire communications.Īn example image from LRO is given in Figure 17. The Lunar Reconnaissance Orbiter (LRO) was implemented to facilitate scientific and engineering-driven mapping of the lunar surface at new spatial scales. The Lunar Reconnaissance Orbiter (LRO) is a NASA space probe orbiting the Moon, performing measurements. Information from the Lyman-Alpha Mapping Project (LAMP) instrument is passed into an I/O board in the C&DH system (HK/IO) and then sent over SpaceWire to the C&DH computer/mass memory. ![]() SpaceWire is also used to pass data from the Command and Data-handling system to the Ka and S-Band communications systems. SpaceWire is used to connect the LRO Cameras (Narrow angle Cameras, NAC1 and NAC2, and Wide Angle Camera, WAC), and Mini-RF radar instrument, to the Command and Data-handling (C&DH) system. With the Lunar Reconnaissance Orbiter (LRO), NASA has returned to the moon, enabling new discoveries and bringing the moon back into the public eye. Once again this is similar to the example architecture of Figure 1.įigure 16 Lunar Reconnaissance Orbiter Data-Handling Architecture The data-handling architecture of LRO is illustrated in Figure 16. The Lunar Reconnaissance Orbiter Camera (LROC) Wide Angle Camera (WAC) and Narrow Angle Cameras (NACs) are on the NASA Lunar Reconnaissance Orbiter (LRO). As of 2019, LRO has enough fuel to continue operations for at least seven more years, and NASA expects to continue utilizing LRO's reconnaissance capabilities to identify sites for lunar landers well into the 2020s.The Lunar Reconnaissance Orbiter (LRO) is a NASA mission currently in orbit around the moon returning images and other scientific data about the lunar surface, see Figure 15.įigure 15 LRO In Lunar Orbit (courtesy NASA) The total cost of the mission is reported as US$583 million, of which $504 million pertains to the main LRO probe and $79 million to the LCROSS satellite. The first images from LRO were published on July 2, 2009, showing a region in the lunar highlands south of Mare Nubium ( Sea of Clouds). LRO was the first mission in NASAs plan to return to the Moon and then to travel to Mars and beyond. The probe has made a 3-D map of the Moon's surface at 100-meter resolution and 98.2% coverage (excluding polar areas in deep shadow), including 0.5-meter resolution images of Apollo landing sites. LRO was launched on the June 18, 2009, as a joint launch with the Lunar Crater Observation and Sensing Satellite (LCROSS) mission (see Section 5.8 ). LRO and LCROSS were launched as part of the United States's Vision for Space Exploration program. ![]() Launched on June 18, 2009, in conjunction with the Lunar Crater Observation and Sensing Satellite (LCROSS), as the vanguard of NASA's Lunar Precursor Robotic Program, LRO was the first United States mission to the Moon in over ten years.
