USS Nimitz has also been fitted with the Lockheed Martin TIS (tactical input segment) digital reconnaissance processing system, which can receive real-time imagery from airborne sensors. Sensors Air search radars include the ITT SPS-48E 3-D, operating at E/F-band; Raytheon SPS49(V)5, C/D-band; and Raytheon mk23 TAS, D-band. Surface search radar is the Northrop Grumman Norden Systems SPS-67V, operating at G-band.

  • This is the first transition ship to a new class of carriers, Gerald R Ford (CVN 78) (also known as CVN 21 and CVNX), planned to start construction in in November 2009 and be delivered in 2015. Northrop Grumman Newport News is the prime contractor for the programme and Raytheon is responsible for weapons system integration. CVN 78 will incorporate new technologies including a new multi-function radar system, volume search radar and open architecture information network, providing a significantly reduced crew requirement and a new nuclear power plant.

      One of the biggest reasons living on Mars seems so impossible is the inexistence of water. With this new discovery, it could not just be possible, but probable, that solving the other issue of breathing could mean we could live on Mars.
  • suggests that water has played a more extensive role than previously envisioned, and that environments capable of sustaining life could exist, according to new research from the University of Gothenburg, Sweden.
  • One important common feature is the presence of permafrost and frozen subsurface water.

      So are these principles based on cells and DNA or just a copy of observations?

    Robotic fish, interesting topic. May lead to a robotic engineering topic.

    What do they plan on doing with these robotic fish after these tests?

      I find it kind of creepy that insects can get into your body and cause injures that look like they were left like a human.

      How can this be possible, that on the upper eyelids were injured?
  • detectives and forensic scientists are examining future corpses recovered from fresh water, they will have data which will help explain unusual markings on the body.
