Launch times are in UTC and are either from the launching agency or estimated by 'walking back' along the ground track to the launch site. Most orbit data and decay information comes from SpaceTrack. The Space-Track data occasionally contains inconsistencies (eg - incorrect re-entry dates or early sets of elements allocated to the wrong object) that need to be corrected from other sources.

To fill the gaps where elements are not formally published, usually because they have a classification of "Secret", some orbits are based on amateur observations. Such data is published near-daily by Mike McCants. Occasionally, orbits are estimated by myself from public data.

Space-Track sometimes has insufficient information to allocate names to objects in its catalogue. In these cases, names are derived from public information.

Apogee and perigee are measured against a spherical Earth with a radius of 6378.145 km, assumed to be situated at the focus of the orbital ellipse. The value for the orbital period is the Anomalistic Period, or time to complete one circuit of the ellipse. It is not the same as the time taken to complete one circuit of the Earth. Care should be exercised when comparing Orbital Focus data with other published orbits because they may have been derived using a different model.

Users can go straight to specific launches by pointing to the page URL followed by the three digit launch number, eg - https://www.OrbitalFocus/Diaries/Launches/Launches.php?year=2015#001

You can keep up to date with changes or mission events by following Orbital Focus at Blue Sky.

Supplies to ISS. Precise launch time 11:00:17 UTC. Intended to dock with the Pirs module at 13:07 UTC. The mission was lost when Progress was damaged by a small explosion in the launch vehicle upper stage caused it to shut down early and deliver Progress to a lower orbit than intended. Although communications were functioning, rapid tumbling of the spacecraft after separating from the launch vehicle meant it could not be controlled. According to TsUP, it re-entered May 8 at 02:04 UTC and was destroyed by frictional heating.

Small Russian military satellite equipped with optical and microwave sensors to monitor naval activity on and below the ocean surface. Carried on second test flight of Soyuz 2-1v. Lost when it remained attached to Volga rocket stage. Volga de-orbit manoeuvre (Dec 6 around 03:30 UTC) resulted in low perigee rather than re-entry because of extra mass during thruster firing. Separated from the Volga Dec 7, probably as a result of heating and buffetting in the upper atmosphere around perigee. Re-entered Dec 8 at 05:43 UTC southbound on the Greenwich meridian near 35° south, above the south Atlantic Ocean.
