Lunar Trailblazer Spacecraft

Why in the news?                                                                                                                                                                                                                                     

Recently, a SpaceX Falcon 9 rocket lifted off from the Kennedy Space Center in Cape Canaveral carrying NASA’s Lunar Trailblazer orbiter.

About Lunar Trailblazer Spacecraft:

• It is an initiative of the National Aeronautics and Space Administration (NASA).
• Objective: It is being sent to find and map water on the moon’s surface.
• It is about the size of a dishwasher and relies on a relatively small propulsion system.
• It weighs about 200 kg and measures about 3.5 metres wide when its solar panels are fully deployed.
• It is scheduled to perform a series of moon flybys and looping orbits over a span of several months to position itself to map the surface in detail.
• It eventually will orbit at an altitude of roughly 100 km and collect high-resolution images of targeted areas to determine the form, distribution and abundance of water and to better understand the lunar water cycle.
• It was built by Lockheed Martin’s space division.
• It is carrying two instruments to achieve its science objectives:
  • High-resolution Volatiles and Minerals Moon Mapper (HVM3): It will look at the moon’s surface for a telltale pattern of light given off by water.
  • Lunar Thermal Mapper (LTM): It will map and measure the lunar surface temperature.
  • When used in conjunction, these two instruments provide the ability to simultaneously identify the various forms of water on the moon, mineralogy, and temperature.
