NASA completes critical design review of Landsat data continuity mission

02.06.2010
The Landsat Data Continuity Mission (LDCM) reached a major milestone last week when it successfully completed its Mission Critical Design Review (CDR).

From May 25-27, an independent review board chaired by Steve Jurczyk, Deputy Director at NASA's Langley Research Center, Hampton, Va., met at NASA's Goddard Space Flight Center in Greenbelt, Md. to conduct the review. The CDR certifies that the maturity of the LDCM design is appropriate to support proceeding with full-scale fabrication, assembly, integration, and test of the mission elements leading to observatory integration and test.

"This review highlighted the collective efforts of a dedicated NASA, U.S. Geological Survey, and industry team working diligently towards the development, launch, and operation of the LDCM," said Bill Ochs, LDCM project manager.

LDCM NASA and industry personnel addressed a variety of topics, including the LDCM spacecraft and its instrument payload, system-level test plans for flight hardware and software, systems engineering, mission assurance, the ground system, and science.

NASA plans to launch LDCM in December 2012 as the follow-on to Landsat-5, launched in 1984, and Landsat-7, launched in 1999. Both satellites continue to supply images and data, but they are operating beyond their design lives. As with preceding Landsat missions, the U.S. Geological Survey will operate LDCM and maintain its data archive once it reaches orbit and begins operational observations. LDCM will extend Landsat's unparalleled record of Earth's changing landscapes.

"We provide data critical to observing dramatic ongoing changes to the global land surface and to understanding the impact of land use change on climate, food and fiber production, water resources, national security, and many other important societal issues," said David Hair, project manager, U.S. Geological Survey, Sioux Falls, S.D.

LDCM will carry evolutionary technology that will improve performance and reliability of the mission," said Jim Irons, LDCM NASA project scientist at Goddard.

The LDCM spacecraft (provided by Orbital Sciences Corp., Gilbert, Ariz) will carry two instruments, the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS). OLI, now being developed by Ball Aerospace & Technologies Corp. will capture images for nine spectral bands in the shortwave portion of the spectrum (visible, near infrared, and shortwave infrared). The Goddard-built TIRS will coincidently collect data for two longwave (thermal) spectral bands. The LDCM ground system will merge the data from both sensors into a single multispectral image product. These data products will be available for free to the general public from the USGS enabling a broad scope of scientific research and land management applications.

For more than 30 years, Landsat satellites have collected data of Earth's continental surfaces to support global change research and applications. This data constitutes the longest continuous record of the Earth's surface as seen from space.

NASA's Goddard Space Flight Center procures and manages the acquisition of the LDCM in partnership with the Department of the Interior's U.S. Geological Survey. NASA will turn over management of the LDCM satellite to the USGS after launch and on-orbit checkout.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Interference as a new method for cooling quantum devices

Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
