Luna-Glob faces new delays in 2015

In 2014 and 2015, as the long-delayed Luna-Glob lander started appearing in metal, its launch had to be officially postponed again from the end of 2017 to the end of 2018 but even that schedule should be viewed as highly unrealistic.

During 2014, Russian space officials promised the launch of Luna Glob between 2017 and 2019. In October, the official TASS news agency quoted Deputy Designer General at NPO Lavochkin Maksim Martynov as saying that the company had been in processing of building a prototype of the spacecraft. A development mockup of the probe's antenna had already been built, Martynov said. A series of tests were planned in 2015, followed by the officially planned launch at the end of 2017 or beginning of 2018, even though these dates were not considered realistic.

Following the conflict in Ukraine and the resulting Western economic sanctions, the Luna-Glob had to be redesigned to exclude hardware, which became a subject to embargo. First of all, it included electronics and communications equipment onboard the spacecraft.

According to the information released by NPO Lavochkin in August 2015, the Luna-Glob lander would lift off on the Soyuz-2-1b/Fregat rocket during a period from November 2018 to January 2019. However, despite a year-long delay from the previously advertised schedule, the latest launch date looked dubious as well, given the fact that NPO Lavochkin was expected to focus all its attention on the ExoMars-2018 project, which would have to be launched the previous May (2018) or, more likely, postponed until 2020.

In any case, the company's planetary mission team could hardly have enough time and resources to prepare both missions in parallel. ExoMars-2018 is already faces extremely tight deadline, which would require maximum effort by all key contractors to bring the spacecraft to the launch pad. If ExoMars-2018 is ultimately postponed until 2020, it is not unreasonable to add at least two more years for the completion of the Luna-Glob's development. Under these circumstances, the mission could fall back as far as 2022 or even further.
