Spock pays the new getup no mind. It is, after all, eminently practical. He takes the water and slips it back onto his belt, although he does not plan on drinking any of it during their stay on this planet. He does not rely on perspiration to keep his internal temperature regulated, so his ability to retain water is much greater than a human's. So, he has reserved that water for Doctor McCoy's usage.

"Unfortunately, I do not, nor do my tricorder readings indicate their presence." He holds up his communicator with his other hand. "Additionally, it seems there is some sort of energy source that is interfering with communications. It is possible that U-283 is generating the disturbance."

U-283, the sun at the center of this particular system, is rather unpredictable. It has a high frequency of sun spots, solar flares, and coronal mass ejections. Due to this, the worlds surrounding it are generally devoid of atmosphere, except in the case of this one. The magnetic field generated by the core was enough to ward off the solar winds and maintain that thin blue line necessary for carbon-based life. It is, however, apparently too hot and dry for life as humans know it.

"It is possible the captain and the others were beamed back to the ship before the interference began."
