Another potential victim of the ExoMars delay could be the Russian-led lunar missions. The Luna-Glob project (a.k.a Luna-25) was to herald Russia’s long-awaited return to lunar exploration with a landing near the northern pole of the Moon. Conceived back in the 1990s, Luna-Glob is currently scheduled for launch in 2019, followed by a lunar orbiter known as Luna-26.However, the Luna series is being built at NPO Lavochkin, the same company that is the prime contractor for the ExoMars project on the Russian side. Still, the director of the Moscow-based Space Research Institute, IKI, Lev Zeleny insisted on Monday that even after the ExoMars had slipped to 2020, his team still aims to launch Luna-Glob in 2019.

Re: Luna-Glob/Luna-25 launch date windows, from NSF's own Nicolas Pillet, dated June 25, 2018:Russia’s Luna-Glob faces technical, political and ballistic issuesSee article for diagram referred to in the quote; my bold of the launch windows.QuoteThe delay consecutive to this technical challenge brings into play additional consequences. During its course to the Moon, Luna-Glob will have to make trajectory corrections using its main engine, giving itself a speed increase, classed as Delta-V.The value of Delta-V cannot be greater than 0.846 km/s, because this is the maximum speed that main engine will be able to nullify when it arrives in the vicinity of the Moon.Since the Moon’s orbit is not a perfect circle, the Delta-V needed to reach it depends on the date of the launch. There are only a few windows during which the Delta-V is below 0.846 km/s. The next window opens in October 2019 and closes in January 2020. This was the targeted window to launch Luna-Glob.Another window will open from June to September 2020, but Delta-V will be very close to the limit. The next window with comfortable margin only opens in May 2021.

Roscosmos shared some details about #Luna25 flight. It will be launched middle October, 2021. Depending on the launch date, the flight to the Moon will take 4,5 or 5,5 days. Preparatory operations for the landing in the lunar orbit will take about 5 days.
Russian media reports possible problems with overweight of #Luna25 spacecraft. The Space Research Institute was instructed to prepare proposals for revising the onboard payload composition after calculating the actual mass summary of the spacecraft. https://ria.ru/20200430/1570778601.html

The plan of commercial space launches of the company "Glavkosmos Launch Services" until 2024 - five of its own from Baikonur and four within the framework of the Federal Space Program of the Russian Federation from Vostochny, in which it is possible to send an associated payload.
Work continues on the Luna-Glob projectAt present, development work is underway on the Luna-Glob project, within the framework of which NPO Lavochkina JSC (part of the Roscosmos State Corporation) creates the Luna-Glob (Luna-25) spacecraft ...In July-September 2020, thermal vacuum tests of the thermal model of the Luna-25 spacecraft were carried out at the branch testing center of the Roscosmos State Corporation of the FKP NIC RCP in Peresvet.The stage of ground testing of the experimental product included: atmospheric thermal tests in a VK 600/300 vacuum chamber, simulating the spacecraft operation at the launch site, as well as thermal vacuum tests simulating the spacecraft operation during flight operation. During these tests, the model was exposed to the vacuum of space, cold "black" space, reflected from the planets of solar radiation, and the solar radiation itself. Heat loads on the spacecraft were reproduced at the stages of launching, flight, artificial satellite of the Moon, landing on the Moon, as well as work on the Moon with an imitation of a lunar day.During the entire test period, continuous recording of all telemetric information (about 600 parameters) on the test object was carried out. The data obtained allow the developers to carry out a complete analysis of the correctness of the calculation of the thermal mathematical model of the Luna-25 spacecraft.After returning to JSC NPO Lavochkina, work with the model does not end; at present, work is underway to continue thermal atmospheric tests, simulating the operation of the spacecraft at the technical complex of the cosmodrome.The Russian spacecraft Luna-25, which will be a continuation of the Soviet stations of the same name series, is scheduled to launch in October 2021. Thematic customer of the project within the framework of the Federal Space Program 2016–2025. is the Russian Academy of Sciences. Luna-25 opens a long-term Russian lunar program, which includes missions to study the Moon from orbit and surface, sampling and delivery of lunar soil to Earth.
В июле-сентябре 2020 года в отраслевом испытательном центре Госкорпорации «Роскосмос» ФКП «НИЦ РКП» в г. Пересвет были проведены тепловакуумные испытания теплового макета КА «Луна-25».
Полученные данные позволяют разработчикам провести полный анализ правильности расчета тепловой математической модели космического аппарата «Луна-25».
Flight samples of scientific instruments of the spacecraft "Luna-25" delivered to NPO Lavochkin08/04/2020In July 2020, flight samples of Russian scientific instruments were delivered from the Space Research Institute to NPO Lavochkin (part of the Roscosmos State Corporation). The specialists of NPO Lavochkina JSC completed the incoming control and began installing them on board the Luna-25 spacecraft (Luna-Glob).The scientific equipment of the first lunar lander created in Russia includes nine instruments: eight Russian and one developed by the European Space Agency. Russian instruments are designed to study the composition, structure, and physical and mechanical properties of the lunar polar regolith, dusty and plasma exosphere in the vicinity of the south pole of the moon.In the course of scientific research, an estimate of the mass fraction of water in the lunar soil at the landing point should be obtained. The scientific equipment also includes a television system, a manipulator complex and a device that provides power switching and command-telemetric exchange of the scientific payload with the service systems of the apparatus. Until now, spacecraft have not visited the polar moon, despite the fact that it is the South Pole of our natural satellite that in the future may become the area for the construction of lunar stations.The launch of Luna-25 is scheduled for October 2021. This project is being implemented by order of the Russian Academy of Sciences as part of the 2016–2025 Federal Space Program. and is funded by the State Corporation Roscosmos. The Luna-25 space project opens a long-term Russian lunar program, which includes missions to study the Moon from orbit and surface, the collection and return of lunar soil to Earth, as well as, in the long term, the construction of a visited lunar base and full-scale development of our satellite.
