Introduction: Astronauts have not explored the lunar surface since December 1972. NASA's new plans for the manned return to the Moon revolve around the construction and establishment of a lunar polar outpost starting around the year 2020. Therefore, in order to achieve NASA's new exploration objectives it seems prudent to dust off certain aspects of the Apollo playbook. The six Apollo lunar lan...
Introduction: The formation of the Nectaris basin is a key event defining the stratigraphy of the Moon. Its absolute age, therefore, is a linchpin for lunar bombardment history. Fernandes et al. [1] gave a thorough account of the history of different samples thought to originate in Nectaris, with the upshot being there is little agreement on what samples represent Nectaris, if any. We are revis...
NASA’s Apollo program is a great achievement of mankind in the 20th century. Previously we had introduced UTD-CRSS Apollo data digitization initiative where we proposed to digitize Apollo mission speech data (~100,000 hours) and develop Spoken Language Technology based algorithms to analyze and understand various aspects of conversational speech[1]. A new 30 track analog audio decoder is design...
The MSC awards ceremony and shuttles preceeding the Mars Office, the Flight Operations, held on the 16th of this month landing. Engineering and Development, served to recall past accomphshAwards were presented to Medical Research and Operations, meats, to contemplate the future, MSC, contractor, and university Flight Crew Operations, Science and to announce and present personnel who had made ma...
Petrographically and chemically well-characterized rocks of the Apollo 14 landing site (12 impact melt breccias, 3 clast-free impact melt rocks, 2 granulitic rocks, 1 cataclastic noritic anorthosite, 1 shocked gabbronorite, 1 mare basalt, and 1 plagioclase single crystal) have been dated by the 40Ar-39Ar technique. The samples represent two different formations at the Apollo 14 site: (1) small ...
The lengthy period since the Apollo landings limits present-day engineers attempting to draw from the experiences of veteran Apollo engineers and astronauts in the design of a new lunar lander. In order to circumvent these limitations, content analyses were performed on the voice transcripts of the Apollo lunar landing missions. The analyses highlighted numerous inefficiencies in the design of ...
Human telomeres are protected from DNA damage by a nucleoprotein complex that includes the repeat-binding factor TRF2. Here, we report that TRF2 regulates the 5' exonuclease activity of its binding partner, Apollo, a member of the metallo-beta-lactamase family that is required for telomere integrity during S phase. TRF2 and Apollo also suppress damage to engineered interstitial telomere repeat ...
[1] The regolith at the Apollo 16 landing site, the only Apollo landing site in the central lunar highlands, contains material derived from a number of sources. A model that accounts for the introduction of basin ejecta and mixing of the megaregolith is used to estimate the abundance of basin material in the Apollo 16 regolith. Megaregolith mixing model estimates of the abundance of primary eje...
This paper describes the Apollo Web Services and Apollo-SV, its related ontology. The Apollo Web Services give an end-user application a single point of access to multiple epidemic simulators. An end user can specify an analytic problem-which we define as a configuration and a query of results-exactly once and submit it to multiple epidemic simulators. The end user represents the analytic probl...
BACKGROUND We developed the Apollo Structured Vocabulary (Apollo-SV)-an OWL2 ontology of phenomena in infectious disease epidemiology and population biology-as part of a project whose goal is to increase the use of epidemic simulators in public health practice. Apollo-SV defines a terminology for use in simulator configuration. Apollo-SV is the product of an ontological analysis of the domain o...
