Ziyuan 3, Vesselsat 2 Launch
CZ-4B, Taiyuan SC
Successful dual launch:

Ziyuan 3 - Manouevrable high resolution remote sensing satellite capable of stereoscopic imaging in sun-synchronous orbit,

Vesselsat 2 - small satellite built by Luxspace (of Luxembourg), carrying two receivers for the Automatic Identification System for ships (AIS).

Sub-orbital Rocket Launch
Terrier-Improved Malemute, Wallops Flight Facility
Successful test flight of future two-stage NASA sounding rocket using surplus rocket motors from other programmes.

Ninety minute launch window opened at 12:30 UTC. Firing delayed by a combination of weather, spurious radar returns suggesting a boat in the first stage impact area, followed by genuine boats!

Mars Science Laboratory - Midcourse Correction
heliocentric orbit
Initial low-thrust firing for 19 minutes using two thrusters (one from each group of four), followed by a further 200 five second bursts using all eight thrust chambers. Firings were over a 175 minute period to provide Δv of 5.5 m/s in order to target the spacecraft on Mars.

The launch vehicle upper stage continued on the original trajectory and will miss Mars by more than 60,000 kilometres in order to avoid contaminating the surface and atmosphere were it to impact.

Fengyun 2F Launch
CZ-3A (Y22), Xichang SC
Successful launch to transfer orbit of a meteorological imaging and climate monitoring satellite for geosynchronous orbit. Expected location - 112° east.

Launched near the start of a window that was about 60 minutes long.

ISS Debris Avoidance & Orbit Adjustment
on orbit
Zvezda thrusters fired for 54 seconds to provide Δv of 0.85 m/s and raise the average height of the ISS orbit by 1.5 km.

New orbit: 388.4 x 412.5 km, 92.32 minutes period, inclination 51°.66 (Russian measurement system).

The purpose was to avoid a fragment from the Cosmos 2251 and Iridium 3 collision. The manoeuvre was also used to set up the ground track for the Progress M-14M launch and rendezvous. As a result, an orbit adjustment already planned for Jan 18 was cancelled.

Phobos-Grunt Re-entry
on orbit
Time was reported by Novosti but may only be a guess of when re-entry started.

WGS-4 Launch
Delta 4 Medium+, CCAFS
Successful launch, at the opening of a 34 minutes long window, to geosynchronous transfer orbit of a military communications satellite. Separated from the launch vehicle at 01:18 UTC.

WGS stands for Wideband Global SATCOM (an acronym of an acronym!). The geosynchronous position may have to become known through amateur tracking but the service area is reported to be the Middle East.

First Block II WGS satellite, providing communications links for troops in the field. A major improvent in the Block II satellites is transmission of airborne intelligence, surveillance and reconnaissance imagery at approximately three times the data rate available through the Block I satellites.

NORAD: 2012-003A/38070 - subject to confirmation

Progress M-13M Undocking
ISS
Precise time: 22:09:35, hooks and latches were released three minutes earlier.

Following engine firings Jan 24 at 01:35:13 UTC to provide Δv of 35 m/s and 02:22:00 (Δv 26 m/s), Progress M-13M will reach a circular orbit at 500 Kilometres altitude.

Chibis-M Launch
Spring Release, Progress M-13M
Small satellite (34.4 kg) released from Progress M-13M by a spring mechanism. Precise time: 23:18:30.

Its purpose is to study physical processes in atmospheric lightning discharges over a wide range of energies and from radio wavelengths to gamma radiation. The expected operational life is one year.

Radio frequencies - CW telemetry beacons at 435.315 and 435.215 MHz.

TsUP gave the orbit as 497 x 514 km, 94.55 min, 51°.62 (Russian measurement system). Space track has yet to publish elements.

Progress M-13M Retrofire
on orbit
Thrusters fired for 235.3 seconds to provide Δv 125.6 m/s, followed by destr uctive re-entry beginning 02:04 UTC, with any unburnt fragments falling in the southern Pacific Ocean at 03:17.56 UTC near 51.4° South, 128.2° West.

Progress M-14M Launch
Soyuz U, Baikonur SC
Successful launch with supplies to ISS. Precise time: 23:06:40 UTC.

Frequencies 121.75 MHz (TORU), 166.000 MHz (+/-128kHz), 922.763 MHz.

Progress M-14M Docking
ISS
Successful docking at the Pirs docking port - precise time 00:08:54 UTC, fourteen seconds later than the target time.

Hooks and latches engaged about 9 minutes later.

ISS - Debris Avoidance & Orbit Adjustment
on orbit
It involved a fragment from the Fengyun 1C ASAT Test. Thrusters on the Zvezda module reportedly fired for 60s to provide Δv of 1m/s and raise the average height of the orbit by 1.7 kilometres.

The manoeuvre resulted in cancellation of an already-planned orbit adjustment for February 2.

Phobos-Grunt - Final Report
Moscow
Delivered!

Roscosmos originally indicated that the full report on the failure would be published Jan 26. It did not appear. An interim report for Jan 20 mentioned by Roscosmos also did not appear.

Later, the delivery date was given as Jan 29 (sunday).

Investigation conducted by Yuri Koptev, former head of the Russian Space Agency.

Navid Launch
Safir (B1?), Iran
Navid is an imaging satellite with 400m resolution built by Sharif University of Technology. The mass is 50kg, and the intended initial orbit was said to be 250 x 375 km at 55° inclination. Design may include an onboard thruster to circularise the orbit at 375 km. The full name is "Navid-e-Elm va Sana't" which means 'Promise of Science and Industry'.

Launch time is estimated from SpaceTrack element sets and is ±1 minute.

Frequency: 435 MHz?
