By relying services provided from lunar orbit, space agencies would be able to design their moon landers without the need for cumbersome communications and navigation devices on board. This would free up space to carry other cargo, making each launch more cost-effective, said Paul Verhoef, ESA...
Phobos can never totally eclipse the Sun, being far smaller than our Moon, and even as close to Mars as it is, never covering more than about half the solar disk. Despite that, as shown in this image (and the one below), the penumbral shadow on the moon is clearly visible on the ...
The evidence that the moon has a profound effect on the timing of reproductive activities of marine animals is compelling. Some moon phase related spawning events are revealed by the constant phase relationship between the timing of "once per year" spawning events and the lunar phase as in the...

SpaceX launched its first two Starlink test craft, named TinTinA and TinTinB, in February 2018. The mission went smoothly. Based on initial data, the company asked regulators for its fleet to be allowed to operate at lower altitudes than originally planned,and the FCC agreed. ...
BEIJING, April 15 (Xinhua) -- China's communication and navigation technology test satellites, Tiandu-1 and Tiandu-2, have successfully carried out experiments on new technologies such as highly reliable Earth-Moon transmission and routing, according to Science and Technology Daily on Monday. ...
White the Sun and the Moon are in sight, the algorithm for autonomous orbit determination using the measured information from the Sun, the Earth and the Moon and the ephemeris of the Sun and the Moon onboard is put forward, and for the stage of eclipse, the proper algorithm for orbit pre...

aThe American space agency Nasa is about to put two new satellites into orbit around the Moon to map its gravity. Scientists expect the data to reveal what exactly lies beneath the Moon's surface, shedding new light on how the lunar body formed and how it's changed through time. This is...
