“…The derived model age of this deposit is estimated to be ∼2.7 Ga; hence, it is substantially younger than the Imbrian-Eratosthenian boundary (3.2 Ga). Haruyama et al (2009) also found that several farside maria (e.g., Apollo, Antoniadi, and the eastern part of Mare Moscoviense) formed in the Eratosthenian Period. Our result indicates that the mare basalt in Campbell is one of the mare deposits formed in the latest phase of farside volcanism.…”

“…As presented by Haruyama et al (2009), comparing model ages of mare basalts on the farside and those on the nearside indicates that the timing of the termination of mare volcanism differed between the farside (∼2.5 Ga) and the nearside (∼1.2 Ga). This difference might be related to the thicker crust (e.g., Head and Wilson, 1992) and/or a deficiency of heat-producing radioactive elements on the farside (e.g., Jolliff et al, 2000).…”

“…Using the high-resolution images, Haruyama et al (2009) carried out crater size-frequency measurements in farside mare deposits within the South Pole-Aitken (SPA) basin and Mare Moscoviense, and found that mare volcanism on the lunar farside lasted ∼2.5 Ga, longer than was previously considered.…”

Age determinations of lunar mare basalts are essential for understanding the thermal evolution of the Moon. In this study, we performed new crater size-frequency measurements in mare deposits in the central region of the northern farside, consisting of Lacus Luxuriae, Buys-Ballot, Campbell, and Kohlschütter, using high-resolution images obtained by SELENE (Kaguya) Terrain Camera. The estimated model ages of the mare deposits range from 2.7 to 3.5 Ga. On the basis of model ages for all investigated mare deposits in the central part of the northern farside, considering the results of previous studies, we concluded that mare volcanism in this region began at least as early as 3.9 Ga and continued until ∼2.6 Ga. From a comparison of model ages in the region and the South Pole-Aitken basin, we found that mare volcanism in these regions ended at the same time, suggesting that the South Pole-Aitken basin formation impact had a minor effect on mare volcanism in the region.

“…The formation ages of farside mare areas were re-estimated by counting craters using high spatial resolution Terrain Camera images. Mare Moscoviense and the Antoniadi and Apollo craters in the SPA basin have been shown to have longlived volcanism to 2.5-2.6Ga compared to a previous estimation of 3.5 Ga 24) . Recently formation ages of nearside mares are also re-estimated in detailed by crater counting method.…”

“…Dating of Apollo and Luna basalts indicated ages ranging between 4.2 and 3.1 Ga during which large basins were filled with lava and solidified. This was taken as an evidence that the Moon has been volcanically inactive for aeons, although occasionally some younger basaltic surfaces with ages of up to~1 Ga, were found (e.g., [63][64][65][66][67]). Chandrayaan-1 results and data from other recent missions viz.…”

), Solar Wind Monitor and Synthetic Aperture Radar gave an insight into an active hydrosphere, with several complex processes operating between lunar surface and its environment. These inferences are based on identification of H, OH, H 2 O, CO 2, Ar etc. in the lunar atmosphere. There are indications that several young (~2 to100 Ma) volcanic regions are present on the Moon as shown by integrated studies using Terrain Mapping Camera and M 3 of Chandrayaan-1 and data from other contemporary missions i.e. Kaguya and Lunar Reconnaissance Orbiter. These data establish that Moon has a dynamic and probably still active interior, in contrast to the generally accepted concept of dormant and quiet Moon. Discovery of Mg spinel anorthosites and finding of kilometer sized crystalline anorthosite exposures by M 3 support the formation of global magma ocean on Moon and differentiation early in its evolutionary history. Furthermore, X-ray Spectrometer data showed anorthositic terrain with composition, high in Al, poor in Ca and low in Mg, Fe and Ti in a nearside southern highland region. This mission provided excellent opportunity for multilateral international cooperation and collaboration in instrumentation and observation in which a dozen countries participated and contributed to the success of the mission. The Mars Orbiter Mission, for study of Martian atmosphere and ionosphere was launched on 5th November, 2013 and is already on its way to Mars. This will be followed by Chandrayaan-2, a well equipped Orbiter-Lander-Rover mission. This article summarises a few results obtained by Chandrayaan-1, which changed some of the concepts about Moon's evolutionary history.
