Star Trek tech we use today (almost)

For the past four decades, Star Trek has been influencing and predicting new gadgets and technologies. How close are we to Trek-inspired phasers, tricorders, and invisibility cloaks?

Star Trek: Starships That Detect Signs of Life vs. Today: Mars Research Spacecraft That Detect Signs of Life



The Enterprise’s onboard sensors were so sophisticated they could detect planetary life forms from orbit. While today’s Mars orbiters and rovers are less refined, they have managed to uncover clues that the Red Planet is hospitable to life. A neutron spectrometer aboard NASA’s Mars Odyssey orbiter (the communications link to the Mars rover shown here), for instance, has detected large amounts of hydrogen in the Martian soil--a promising sign of the presence of water ice and a life-friendly environment--but it isn’t equipped to find and identify actual life forms. Future missions (such as the ExoMars rover, which will drill into the Martian soil for organic molecules) will have better life-sniffing skills.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
