China Chang’E-3 performed soft landing at the plains of Sinus Iridum on lunar surface on December 14th 2013 successfully; it opened a new window for observing lunar surface with radiometric tracking which many lunar scientific researchers always pursue for. Since July 2014, OCEL (Observing Chang’E-3 Lander with VLBI) project has been conducted jointly by IVS (International VLBI Service of Geodesy and Astrometry) and BACC (Beijing Aerospace Control Center), a global IVS R&D network augmented with two China Deep Space Stations configured for OCEL. This paper presents the current status and preliminary result of the OCEL and mainly focuses on determination of the lander position, which is about 7 meter in height and 14 meter in plane of lunar surface with respect to LRO (Lunar Reconnaissance Orbiter). Based on accuracy analysis, further optimized OCEL sessions will make use of this target-of-opportunity, the Chang’E-3 lunar lander, as long as it is working. With higher accurate radiometric observables, more prospective contribution to earth and lunar science is expected by combining with LLR.

The Lunar Lander Vikram of the Moon Mission Chandrayaan 2 of the Indian Space Research Organization (ISRO) lost communication with the Lunar Orbiter and the mission control nearly 2.1 kms above the lunar surface during its landing on the Moon on 7th September, 2019. The exact location and the sight of the lost lander and rover are still elusive. We present here the exact location and first images of the lander Vikram and rover Pragyaan sighted on the lunar surface. It is evident from the processed images that the lander was intact and in single piece on landing away from the scheduled site and its ramp was deployed to successfully release the rover Pragyan on to the lunar surface. This contradicts earlier reports that the lander was disintegrated into small pieces and debris which were scattered far away from the proposed landing site.

The success of the International Space Station project has inspired the partners to review possible steps in space exploration beyond Low Earth Orbit. The Moon, Mars, or asteroids - the priorities of partners’ national programs could be different. Understanding of the deep space exploration viability by the joint team led partners to consideration regarding Cis-Lunar Spaceport which will become a Spaceport and should facilitate the implementation of the national programs. At the present time a concept of the Spaceport located on high-elliptical lunar orbit is being widely discussed. The Spaceport is considered to be a transportation hub supporting deep space exploration programs: missions to the Moon, asteroids, Mars and other natural and artificial objects. Different schemes of crew delivery to the lunar surface using Lunar Lander based and serviced at the Spaceport are compared in the paper. The Spaceport utilization significantly reduces transportation operations time limits and provides conditions for reusable lunar spacecraft implementation. Key words: Cislunar spaceport, high-elliptical lunar orbit, ascent module, descant module, reusable lunar crew vehicle.
