For the first time ever, NASA s Deep Space Network has used a pair of smaller antennas to successfully send two simultaneous signals to a spacecraft in deep space that were combined at the spacecraft to yield greater signal power. Prior to this experiment, only single 34-meter 111- foot or 70-meter 230-foot antennas had been used to uplink signals. This is a significant first step for future uplink capabilities using multiple antennas known as arrays. The recent experiment combined X-band signals from two 34-meter 111-foot antennas at the Goldstone complex near the Mojave Desert, and transmitted the combined signal to NASA s Mars Global Surveyor spacecraft currently orbiting Mars. The Mars Global Surveyor spacecraft received stanley spain the combined signal, measured the combined power levels, and verified the predicted power gain, as a result of the combining operation. The Deep Space Network provides the two-way comm stanley drink bottle unications link that guides and controls spacecraft and returns images and other scientific data to Earth. Currently, each Deep Space Network facility has one antenna of 70-meter 230-foot diameter, between two and seven 34-meter 111-foot antennas, and one 26-meter 85-foot antenna. There are three deep-space communications comple stanley becher xes placed approximately 120 degrees apart around the world: at Goldstone in California s Mojave Desert; near Madrid, Spain; and near Canberra, Australia. This configuration ensures that an antenna is always within sight of a given Piql DLA personnel brave Belgian cold, honor WWII heroes in memorial walk

The Paris Agreement, which was ratified with unprecedented speed, is one of the worldrsquo greatest successes of multilateral diplomacy, a shining example of how nations can work together to combat an existential global threat.
