“…If the dominant contribution to the gravity anomaly is from the basalt fill (Phillips et al, 1972), this pattern would suggest an axially syrnmetric, Gaussian-shaped accumulation with the greatest thickness of the basalts near the basin center. The most recent gravity models (Konopliv et al, 1998(Konopliv et al, , 2001; Konopliv and Yuan, 1999), however, show that the anomaly for Serenitatis does not have a "bull's eye" pattern (Fig. 4).…”

“…la). The positive anomaly is attributed to the uncompensated mare basalts (Phillips et al, 1972) and the presence of a dense mantle "plug" formed by post-impact mantle rebound (Wise and Yates, 1970;Solomon and Head, 1979) (for a summary discussion of the relative contribution of mantle material and the basalt fill to the gravity see (Konopliv et al, 2001). The grid was generated by truncating LP 165P at degree and order 1 10.…”

“…Although this interpretation of the subsurface structure is non-unique, it is consistent with the available data. Gravity data for Crisium, Humorum, Imbrium, and Nectaris suggest that the mare fill in these basins may also be roughly uniform in thickness and better approximated by broad tabular-shaped basalt sequences (Konopliv et al, 1998(Konopliv et al, , 2001). …”

“…The culmination of a century-long search [1][2][3][4][5][6][7][8][9][10], GW detection is now emerging as a new tool with which to study the Universe, illuminating previously invisible astrophysical phenomena. In parallel, the developments of laser cooling and the laser frequency comb have given rise to optical atomic clocks with accuracies and stabilities at the 10 −18 level [11][12][13][14][15].…”

Gravitational wave detection with optical lattice atomic clocks

We propose a space-based gravitational wave (GW) detector consisting of two spatially separated, dragfree satellites sharing ultrastable optical laser light over a single baseline. Each satellite contains an optical lattice atomic clock, which serves as a sensitive, narrowband detector of the local frequency of the shared laser light. A synchronized two-clock comparison between the satellites will be sensitive to the effective Doppler shifts induced by incident GWs at a level competitive with other proposed space-based GW detectors, while providing complementary features. The detected signal is a differential frequency shift of the shared laser light due to the relative velocity of the satellites, and the detection window can be tuned through the control sequence applied to the atoms' internal states. This scheme enables the detection of GWs from continuous, spectrally narrow sources, such as compact binary inspirals, with frequencies ranging from ∼3 mHz-10 Hz without loss of sensitivity, thereby bridging the detection gap between spacebased and terrestrial optical interferometric GW detectors. Our proposed GW detector employs just two satellites, is compatible with integration with an optical interferometric detector, and requires only realistic improvements to existing ground-based clock and laser technologies.

“…Additionally, due to the synchronous rotation of the Moon around the Earth, all derived models lack information from the far-side. The most recent and probably best model available is the JPL Lunar Prospector mission result LP150Q (Konopliv et al, 2001) which is complete to degree and order 150 of a spherical harmonic representation. The model can resolve smallscale features up to 36 km half-wavelength with an approximate accuracy of about 30 mGal on the near-side, but, due to the inhomogeneous input data which require strong constraints in the solution process, the model errors are definitely much larger (up to 200 mGal) on the farside (Wiezcorek, 2007).…”

A simulation study has been performed at GFZ Potsdam, which shows the anticipated improvement of the lunar gravity field model with respect to current (LP150Q model) or nearfuture (SELENE) knowledge in the framework of the planned German Lunar Explorations Orbiter (LEO) mission, based on PRARE-L (Precise Range And Range-rate EquipmentLunar version) Satellite-to-Satellite (SST) and satellite-Earth-satellite (SEST) tracking observations. It is shown that the global mean error of the lunar gravity field can be reduced to less than 0.1 mGal at a spatial resolution of 50 km. In the spectral domain, this means a factor of 10 (long wavelengths) and some 100 (mid to short wavelengths) improvement as compared to predictions for SELENE or a factor of 1000 with respect to LP150Q. Furthermore, a higher spatial resolution of up to 28 km seems feasible and would correspond to a factor of 2-3 improvement of SELENE results. Moreover, PRARE-L is expected to derive the low-degree coefficients of the lunar gravity field with unprecedented accuracy. Considering long mission duration (at least 1 year is planned) this would allow for the first time a precise direct determination of the low-degree tidal Love numbers of the Moon and, in combination with high precision SEST, would provide an experimental basis to study relativistic effects such as the periselenium advance in the Earth-Moon system.
