The first direct evidence of water vapor near the Moon was obtained by the Apollo 14 ALSEP Suprathermal Ion Detector Experiment, SIDE, on March 7, 1971. A series of bursts of water vapor ions were observed by the instrument mass spectrometer at the lunar surface near the Apollo 14 landing site.
Listed below are the largest ocean, lakes and seas in the Solar System and beyond includes single bodies of water or other liquid on or near the surface of a solid round body (terrestrial planet, planetoid, or moon). Currently, cold surface bodies of liquid are found on two worlds in the Solar System, Earth and Saturn's moon Titan. [1]
The current Venusian atmosphere has only ~200 mg/kg H 2 O(g) in its atmosphere and the pressure and temperature regime makes water unstable on its surface. Nevertheless, assuming that early Venus's H 2 O had a ratio between deuterium (heavy hydrogen, 2H) and hydrogen (1H) similar to Earth's Vienna Standard Mean Ocean Water of 1.6×10 −4, [7] the current D/H ratio in the Venusian atmosphere ...
Once in the vicinity of the Moon, the lander spent approximately one more Earth-day orbiting the Moon. This set February 22, 2024 at 11:24 PM UTC as the lander's lunar landing date. [ 23 ] [ 24 ] The initial aim was to land within the Malapert-A crater, which is about 300 km (190 mi) from the lunar south pole.
Soil studied by India’s Chandrayaan-3 mission near the lunar south pole adds support to the theory that the moon once had a magma ocean billions of years ago. Data from India’s historic moon ...
Geological studies of the Moon are based on a combination of Earth-based telescope observations, measurements from orbiting spacecraft, lunar samples, and geophysical data. . Six locations were sampled directly during the crewed Apollo program landings from 1969 to 1972, which returned 382 kilograms (842 lb) of lunar rock and lunar soil to Earth [8] In addition, three robotic Soviet Luna ...
The rotational axis of the Moon passes through Shackleton, near the rim. The crater is 21 km (13 miles) in diameter and 4.2 km (2.6 miles) deep. [2] From the Earth, it is viewed edge-on in a region of rough, cratered terrain. It is located within the South Pole–Aitken basin on a massif. [3]
Tycho (/ ˈ t aɪ k oʊ /) is a prominent lunar impact crater located in the southern lunar highlands, named after the Danish astronomer Tycho Brahe (1546–1601). [2] It is estimated to be 108 million years old.
