METEOR-M 2

METEOR-M 2 (also catalogued under the designation Meteor-M No.2-1, NORAD ID 40069, COSPAR 2014-037A) is a Russian Earth-observation satellite operated by the Russian government and dedicated to meteorological monitoring from a low, polar orbit. Launched in July 2014, it forms part of the Meteor-M programme, a modernised lineage of Soviet-era weather satellites that Russia has continued to develop and deploy in the post-Soviet era. As of the time of writing, the spacecraft remains in orbit, circling the Earth on a routine cadence that keeps it in continuous contact with high-latitude ground stations.

Mission and Purpose

The Meteor-M series was conceived to re-establish and eventually surpass the meteorological satellite capabilities that the Soviet Union had built up during the Cold War. By the early 2000s, Russia's space-based weather infrastructure had aged substantially, and the Meteor-M programme was initiated to replace it with more capable, longer-lived platforms. METEOR-M 2 represents the second spacecraft in this modernised family to reach orbit, following on from its predecessor as part of a planned constellation intended to deliver uninterrupted coverage of the Russian Federation and adjacent regions.

Weather satellites in sun-synchronous low Earth orbit serve a well-defined suite of functions. By passing repeatedly over the same ground track at approximately the same local solar time each day, they enable systematic, comparable measurements of cloud cover, sea-surface temperatures, ice extent, atmospheric humidity profiles, and a range of other parameters that feed into numerical weather prediction models. For a country with the geographic scale of Russia — stretching across eleven time zones and encompassing vast Arctic and sub-Arctic territories — domestic satellite coverage is not merely convenient but operationally essential. Ground-based weather networks thin out dramatically at high latitudes, making satellite data the primary observational source across large swaths of Siberia and the Russian Arctic coast.

METEOR-M 2 was designed with a planned operational lifespan of five years, a design target that reflects the balance between technological ambition and the harsh realities of the space environment. Whether the satellite fulfilled that design life or continues to transmit usable data is not definitively recorded in the public catalog, and its current mission status remains unconfirmed in openly available sources. Regardless of its functional status, it continues to orbit and is actively tracked.

Orbit and Tracking

METEOR-M 2 occupies a sun-synchronous orbit (SSO), a specialised class of near-polar orbit in which the orbital plane precesses at a rate that keeps it aligned at a constant angle relative to the Sun throughout the year. This geometry ensures that the satellite crosses any given latitude at roughly the same local solar illumination conditions on every pass, which is critical for producing consistent, long-term datasets — sunlight angles affect reflected radiance measurements, and inconsistency in illumination would introduce systematic errors into climate and weather records.

The satellite's current orbital parameters reflect a well-maintained, nearly circular trajectory. Its apogee stands at approximately 830 km above Earth's surface, while its perigee sits at around 820 km, yielding a remarkably low eccentricity and confirming that the orbit is close to a perfect circle. An inclination of 98.5° places it firmly in retrograde sun-synchronous territory — inclinations above 90° indicate that the satellite travels partly against the direction of Earth's rotation, a requirement for achieving the sun-synchronous precession rate at these altitudes.

With an orbital period of 101.2 minutes, METEOR-M 2 completes roughly fourteen full orbits of the Earth each day. Over the course of those orbits, Earth rotates beneath it, meaning the satellite's ground track shifts westward with each successive pass and, over the course of roughly two weeks, sweeps out complete global coverage. This repeat pattern is a fundamental feature exploited by meteorological satellite operators when planning ground reception networks and data assimilation schedules.

At an altitude between 820 and 830 km, the satellite is high enough to avoid significant atmospheric drag from the residual upper atmosphere, which contributes to the orbital stability visible in the near-circular shape of its trajectory. Objects at lower altitudes in very elliptical orbits tend to circularise and decay more rapidly; METEOR-M 2's orbit suggests it has experienced minimal uncompensated drag since launch, and it shows no indication of imminent reentry.

Tracking data for METEOR-M 2 is maintained through the U.S. Space Surveillance Network and is publicly accessible via the NORAD catalog under ID 40069. This allows amateur observers, researchers, and professional operators alike to obtain up-to-date two-line element sets and predict the satellite's position with high precision.

Design and Operator

METEOR-M 2 is operated by the Russian government, with oversight falling under the relevant Russian federal space and meteorological authorities. The spacecraft's manufacturer is not publicly documented in the tracking catalog, though the Meteor-M programme as a whole has historically been associated with Russian aerospace industrial enterprises involved in Earth-observation satellite construction.

The satellite was lofted into orbit by a Soyuz-2.1b launch vehicle paired with a Fregat upper stage — a reliable and well-proven combination that has been used across a wide range of Russian civil and scientific missions. The Soyuz-2.1b variant features an upgraded third stage engine compared to earlier Soyuz configurations, providing enhanced performance for heavier payloads or higher target orbits, while the Fregat upper stage supplies the precise orbital injection needed to achieve the specific sun-synchronous parameters required for a meteorological mission. The launch took place in July 2014 from a Russian launch facility, placing the spacecraft into the intended orbit.

The mass of METEOR-M 2 is not recorded in the publicly available tracking catalog entry, so no figure can be reliably stated. Similarly, the detailed instrument complement — which in such satellites typically includes multispectral imagers, microwave sounders, and other remote sensing payloads — is not specified in the verified public record for this object.

What can be stated is that the satellite was built to operate for approximately five years, implying a design philosophy oriented toward a defined science and operational return before the accumulation of component wear and orbital hazards would risk mission reliability. Five-year design lives are common in this class of satellite, representing a pragmatic trade-off between cost, radiation hardening requirements, and the anticipated pace of technology refresh in a national constellation.

Legacy and Current Status

METEOR-M 2 arrived in orbit at a time when Russia was actively working to rebuild its meteorological satellite infrastructure. The Meteor-M programme has expanded since the satellite's launch, with subsequent spacecraft carrying forward and developing the capabilities first implemented in the series. Within the context of that broader constellation effort, METEOR-M 2 occupies the position of an early operational example of the modernised generation — a satellite that helped demonstrate the architecture's viability in orbit before later missions refined and improved upon it.

The satellite's continued presence in orbit, more than a decade after its July 2014 launch, is itself noteworthy. Objects that remain in sun-synchronous orbits at these altitudes for extended periods without active station-keeping face the gradual influence of atmospheric drag, solar radiation pressure, and gravitational perturbations. The fact that METEOR-M 2 remains in a nearly circular orbit with an apogee and perigee separated by only 10 km suggests that either some form of orbital maintenance has been performed, or that the natural perturbation environment at this altitude is sufficiently benign to preserve orbital shape over these timescales — a characteristic of the 800–850 km altitude band.

Its current operational status — whether it is still transmitting data, operating in a reduced capacity, or has been declared non-operational — is not confirmed in the public tracking record. This ambiguity is not unusual for government-operated remote sensing satellites, where detailed mission health information may not be routinely released to the public.

How to Spot It

At an orbital altitude of roughly 820 to 830 km, METEOR-M 2 is a moderately sized satellite that may be visible to the naked eye under the right conditions, though its brightness will vary depending on its orientation, the angle of solar illumination, and local sky conditions. Like most low Earth orbit spacecraft, it will appear as a steady, non-blinking point of light moving steadily across the sky from horizon to horizon over the course of a few minutes.

The best opportunities for visual observation occur during twilight — shortly after sunset or before sunrise — when the observer on the ground is in darkness but the satellite remains sunlit at altitude. With an orbital period of 101.2 minutes and an inclination of 98.5°, passes can occur at a wide range of sky positions and azimuths, and high-inclination orbits like this one are observable from virtually any location on Earth's surface, including polar regions. Accurate pass predictions can be generated using the NORAD catalog element sets available on this site, which are regularly updated to account for any minor orbital evolution.
