    Their plans are not set in stone and the often evaluate how plans are going half way through and work out if it is working properly or if changes need to be made or things not working cancelled and replaced with other programmes.

    If we detected a comet on collision course with earth they wont say we can't do anything till the current plan up to 2027 is finished before we can add a new programme or job to our schedule.

    🔴 “Luna-25”: preliminary results of work to determine the reasons for the abnormal functioning of the station

    On August 19, when issuing a corrective impulse to transfer the spacecraft from a circular lunar orbit to an elliptical pre-landing orbit, the Luna-25 propulsion system operated for 127 seconds instead of the planned 84 seconds. As a result, the station switched to an undesigned open orbit and collided with the lunar surface.

    It was established that the most likely cause of the accident was the abnormal functioning of the on-board control complex, associated with the failure to turn on the accelerometer unit in the BIUS-L device (angular velocity measurement unit) due to the possible entry into one data array of commands with different priorities for their execution by the device. In this case, the distribution of commands in data arrays is random (probabilistic) in nature.

    In this regard, the on-board control complex received zero signals from the accelerometers of the BIUS-L device. This did not allow, when issuing a corrective pulse, to record the moment the required speed was reached and to timely turn off the spacecraft propulsion system, as a result of which its shutdown occurred according to a temporary setting.

    Recommendations for additional activities for subsequent lunar missions have been formed.

    Thats a lot of gobbledegook that simply means "software error".

    Lack of testing.. again. Just like Phobos Grunt. Just like Phobos 1 & 2.

    Getting the flight control system fully validated is an absolute necessity. Roskosmos management need to hang their heads in shame. angry

    Looks like there will no be repeat of Luna-25, but instead the Luna-27 mission will be a pair of craft.  thumbsup  IMHO this is a better outcome.

    There will be no shift to the left in the Russian lunar program and the next launch to the Moon will take place only in four years. This became known from the updated plan for upcoming missions, which was presented at the 14th international symposium on solar system research, held at the Space Research Institute of the Russian Academy of Sciences.
    The new plan has two differences from the old one.
    Firstly, the launch date of the Luna-27 station has been slightly adjusted. Now the launch of this mission is listed as 2028+, and not definitely 2028, as it was before.
    Secondly, Luna-27 now has a double. It will be launched into space a few months after the main mission.
    No “training” flights are planned to revive our skills in soft landing on the Moon.
    Yes, apparently, our celestial neighbor will have to wait a long time for the Russian to leave his traces on its surface.

    Roscosmos is considering a proposal from the Russian Academy of Sciences to create two Luna-27 spacecraft.

    The head of the state corporation, Yuri Borisov, noted that the landing site for the Luna-27 spacecraft will be determined by the orbital Luna-26.

    MOSCOW, December 26. /TASS/. Roscosmos is considering a proposal from the Russian Academy of Sciences to create two Luna-27 spacecraft in order to increase reliability. This was announced by the head of Roscosmos Yuri Borisov.

    "The [Russian] Academy of Sciences came up with a proposal to make two satellites - Luna-27a and Luna-27b - for reliability and to ensure the guaranteed completion of this mission. We are now considering their proposal, but nevertheless, 2028 is certainly in the deadlines are worth it,” Borisov said in an interview with Russia-24 .

    According to him, the landing site for the Luna-27 spacecraft will be determined by the orbital Luna-26, work on which is already in full swing. “The launch is planned for 2027,” added the head of Roscosmos.

    Borisov recalled that the situation with Luna-25 greatly upset all workers in the field, especially the young team of the NPO named after. S. A. Lavochkina. “But we need to put our worries aside and roll up our sleeves to work on a new project,” he emphasized.

    The Soyuz-2.1b launch vehicle with the Luna-25 automatic station launched from the Vostochny Cosmodrome on August 11. After sending a pulse to the device to form its pre-landing elliptical orbit, communication with the spacecraft was interrupted. It ceased to exist when it collided with the surface of the Moon.

    The interdepartmental commission came to the conclusion that the accident of the Luna-25 automatic station occurred due to abnormal functioning of the on-board control complex associated with the failure to turn on the accelerometer unit in the BIUS-L device (unit for measuring angular velocities).

    Personally against this shit, the moon is our one and only moon, say a huge rock hits the nuclear reactor or some retard crashes their rover into it, is the moon's surface good enough to deal with a Chernobyl incident?

    Russia, China consider putting nuclear power reactor on Moon in 2033-2035 — Roscosmos
    According to CEO Yury Borisov, such a mission will have to be automated, with the necessary technological solutions almost ready for it
    SIRIUS /Federal Territory/, March 5. /TASS/. Russia and China are mulling a project to install a nuclear reactor on the Moon in 2033-2035, Roscosmos CEO Yury Borisov announced at the World Youth Festival.

    "Today, we are seriously considering a project to deliver to the Moon and mount a power reactor there jointly with our Chinese partners somewhere between 2033 and 2035," he said.

    According to Borisov, such a mission will have to be automated, with the necessary technological solutions almost ready for it.

    In March 2021, Russia’s State Space Corporation Roscosmos and the China National Space Administration (CNSA) signed a memorandum of mutual understanding on behalf of their governments on cooperation in creating the International Lunar Research Station (ILRS). Under the project, China plans to send three missions: Chang’e 6, Chang’e 7 and Chang’e 8. The first lunar missions would test key technology to create a roadmap for building a robotic base for experiments and research that could be operated remotely. The first lunar mission is scheduled for 2026, and the project should be wrapped up in 2028.

    The moon orbits outside the earths magnetic field so cosmic radiation means you would need protection from radiation anyway... and a lack of atmosphere on the moon means the radiation would remain rather localised.

    The point is that the polar regions they want to send people to because of the possibility of ice is also a bad place for solar panels so nuclear is really your only option.

    Nuclear power in space is going to be necessary, even if it is just as a backup because there really only is solar and nuclear.

    On Mars the possibility of wind power generation is an option but how reliable that would be is another matter and of course would be totally useless on the Moon.

    Forget wind power on mars, the atmosphere is exceedingly thin, only ~6.5 millibars or 0.6% of earths atmosphere at sea level.  While the winds are sufficient to lift miniscule dust particles they won't be effective at spinning a turbine as there is just too little energy.

    Moon bases will likely use both solar and nuclear.  Solar will supplement the energy needs during the 2 weeks of daylight but nuclear will be essential for the 2 weeks of night.

    Moon (and everything else) is constantly cumblasted with amounts of space radiation that make human made nuclear disasters look like littering
