Techno-Archaeology Rescues Climate Data from Early Satellites, National Snow and Ice Data Center

Image: Forty-three years after the Nimbus II satellite collected these data, a team from NSIDC and NASA recovered a global image from September 23, 1966. In this view over Antarctica, overlaid on Google Earth, the Ross Ice Shelf appears clearly at left.

"Starting with the methods developed for the Lunar Orbiter Image Recovery Project (LOIRP) at NASA Ames Research Park, a team at NSIDC worked with Dennis Wingo at LOIRP to search NASA archives for the original Nimbus tapes containing raw images and calibrations. Their first goal was to read and reprocess the data at a higher resolution, removing errors resulting from the limits of the original processing."

Technoarcheology and Earth Sciences, the Recovery of Nimbus II High Resolution Infrared Radiometer Data

"In 2008 the Lunar Orbiter Image Recovery Project (LOIRP) began a NASA ESMD sponsored project to resurrect 43+ year old Ampex FR-900 instrumentation tape drives for the purpose of recovering, before the capability to do so becomes impossible, the last surviving master tapes from the five Lunar Orbiter spaceraft that orbited the Moon in support of Apollo in 1966-67. Our project is proceeding on our task to do so. During our research on the Ampex tape drives we scoured the NASA Technical Reports Server as well as any other source we could get our hands on. During this search, we found, through a Cadillac (yes the car) user group, a gentleman from Alaska who had worked on these drives during the 1960's. We were able to connect and while he had retired and the units were long gone to that great scrap yard in the sky, he told me something interesting. He said that during his time working on the drives that they had sent "miles and miles, thousands of tapes" to NASA during the Nimbus weather satellite program. This is where our new tale begins."

"One of the things that the LOIRP team is going to do is to take the Nimbus II HRIR data from August 23rd 1966 and overlay that with the Lunar Orbiter 1 data on the same date for a composite mosaic. There is potential for a significant synergy between Lunar Orbiter, Apollo, and Nimbus II and III data sets. This type of synergy could provide many benefits to the Earth sciences community."

The STS-130 patch was designed by the crew to reflect both the objectives of the mission and its place in the history of human spaceflight. The main goal of the mission is to deliver Node 3 and the Cupola to the International Space Station (ISS). Node 3, named "Tranquility," will contain life support systems enabling continued human presence in orbit aboard the ISS. The shape of the patch represents the Cupola, which is the windowed robotics viewing station, from which astronauts will have the opportunity not only to monitor a variety of ISS operations, but also to study our home planet.

The image of Earth depicted in the patch is the first photograph of the Earth taken from the moon by Lunar Orbiter I on August 23, 1966. As both a past and a future destination for explorers from the planet Earth, the moon is thus represented symbolically in the STS-130 patch.
