collection in nrts

NTRS provides access to approximately 500,000 aerospace related citations, 90,000 full-text online documents, and 111,000 images and videos. The types of information include: conference papers, images, journal articles, photos, meeting papers, movies, patents, research reports, and technical videos--scientific and technical information (STI) created or funded by NASA.

NTRS integrates three separate information collections and enables search and retrieval of information collectively or separately.

It's time for NASA to get back on track

The Review of the U.S. Human Space Flight Plans Committee is expected to publish its report at the end of the month. It is charged with the thankless task of reaffirming or redirecting NASA's vision for space exploration. What should the agency be doing with its existing hardware and its plans for the future? The real catch is the part of their charter that reads, “fitting within the current budget profile for NASA exploration activities.” Money isn't NASA's only problem, but it has been its biggest problem for decades. NASA is one of the most successful agencies in history, providing the best return on investment of any government agency in my lifetime. My main concerns with NASA's plans going forward include the decision to ground the space shuttle, the woefully inadequate funding for the last several decades and the absence of a space program that will restore the sense of wonder and adventure to space exploration that we knew in the 1960s. The continuing debate for ...

NASA STI PROGRAMMES AND NRTS

The NASA Scientific and Technical Information (STI) Program supports the acquisition, organization, management, dissemination, and long-term retention and safeguarding of STI relevant to NASA's research and development and missions. The purpose of the NASA STI Program is to: Help ensure that NASA research is cost-effective by providing NASA personnel with access to existing NASA and worldwide research results. In this way, the NASA STI Program reduces duplication and increases productivity, which not only increases the yield of the tax dollars invested in NASA research but also accelerates scientific progress Support the work of the U.S. aerospace industries. To maintain their competitiveness, they rely on current knowledge of R & D developments in NASA, the United States, and the world Share the results of NASA's research with the world, as appropriate The STI Program sponsors the NASA Technical Report Server (NTRS) and other STI related products including...

Nasa dominates as rivals play catch-up

Engineers opened the hatch of the Mars 500 space capsule this week and six "cosmonauts" emerged from a simulated three-month interplanetary flight. Next year, the Russian and European space agencies will send another crew on a longer simulated mission to Mars and back, lasting a year and a half. The cosmonauts - four from Russia and two from western Europe - live in isolation in a mock spacecraft outside Moscow, experiencing conditions as close as possible to a real flight. There is, for instance, a communication delay of up to 20 minutes each way, to reflect the time taken for radio signals to travel between Mars and Earth. But the very fact that the two agencies are spending millions to assess the psychological and medical effects of interplanetary travel is a statement of long-term intent. dreaming of mars dreaming of mars "I hope that the scientific data we have provided over the last two months will help to make a mission to Mars possible," said Oliver Kni...
