This morning, the LOLA instrument was turned on (not the lasers, just the receptors), and began collecting Laser Ranging data later in the afternoon !
Those data are not exactly like SLR (Satellite Laser Ranging), because it is not a two-way link, but they are timetagged at both the transmitting end (the Goddard station) and the receiving end (the LOLA receptor #1, through a fiber optics between a small telescope attached to the Earth-pointing high-gain antenna and the Moon-pointing LOLA instrument). They give an absolute range betwen the Earth and LRO (after some careful correlation and calibration), which will help improve the position knowledge of the spacecraft and benefit all the instruments (especially LROC, which turned on today for a bit!) (see the LRO blog) |
