Wikipedia — Mayak (spacecraft) (in Russian)

Mayak (Russian Маяк ‘lighthouse’) is a Cubesat 3U-sized spacecraft designed by young engineers of Moscow Polytechnic University. It is the first Russian crowdfunded spacecraft with a record low cost of 2 million roubles (€29,000, $33,000).

The satellite is planned to be launched on 14 July 2017 from the Site 31/6 at the Baikonur Cosmodrome, Kazakhstan. It will be put into a 600 km orbit using a Soyuz-2.1a rocket with a Fregat-M upper stage alongside 72 other satellites (Canopus-V-IK, Zvezda, four SatByul Co. LTD satellites, two Corvus-BC, AISSat-3, Lemur+, Tyvark, MKA-N, Flock 2k).

The spacecraft contains a solar reflector made of metallized film 20 times thinner than a human hair. After getting into orbit, it will be deployed and form a tetrahedron. For 25 days, Mayak will become the brightest shimmering star in the night sky with the apparent magnitude of −10 (1.6 times brighter than the Iridium flare (magnitude −9.5)). The Mayak solar reflector is intended to be a reference object for space object apparent magnitude estimations. During the tracking of the flight of the satellite in upper Earth atmosphere, new data on the gas density at the given altitudes will be acquired. The flight can also be considered as an aerobraking device flight test. Such devices may be used for deorbiting space junk in the future.

The spacecraft includes:

  • solar reflector
  • reflective surfaces
  • reflector container
  • deploying mechanism
  • control system
  • chemical electricity source
  • propulsion system
  • load-bearing unit

Dimensions: 3 × 3 × 2.45 m
Orbital altitude: 600 km
Orbital inclination: 98°

This is clearly evidence that all stars are faked. NASA faked the lunar landings- EXPOSED!

I've tried to observe it again. Nothing. Not even its own intrinsic shine. I don't think the reflectors have opened at all.

It's just a tiny box less shiny than that white toolbag from ISS.

With what instrument and where?

My eyes. :D

I'll try with binoculars, next.
