Shuttle and Station

The Progress M-10M cargo supply ship docked with the Station's Pirs module at 1428 UTC on Apr 29.

Space Shuttle OV-105 Endeavour was launched on mission STS-134 on May 16. It flew to orbit using solid rocket motors RSRM-113 and External Tank ET-122. The RSRMs fell back to the Atlantic and were recovered, after arcing into the mesosphere. ET-122, which had been repaired after suffering significant damage in its New Orleans factory during Hurricane Katrina, reached a 57 x 227 km marginal orbit; after apogee around 1336 UTC, it reentered at first perigee over the South Pacific at around 1405 UTC. Endeavour fired its OMS engines at apogee, entering a 231 x 324 km x 51.6 deg orbit at 1336 UTC. After a series of rendezvous burns, it is approaching the International Space Station for a docking planned on May 18.

Endeavour will deliver a set of spare equipment to the Station on the ELC-3 carrier, and install the massive AMS-02 particle detector which will search for antimatter. The STORRM lidar is a test of rendezvous and docking technology to be used on the future Orion spaceship; MISSE experiments are temporarily attached to the Station to study the effects of exposing various materials to space. STP-H3 is a set of US Defense Dept. experiments in the Space Test Program series, including experimental thermal control systems and space environment sensors.

Crew of STS-134 are NASA's Mark Kelly, Greg H. Johnson, Mike Fincke, Greg Chamitoff, Andrew Feustel, and the European Space Agency's Roberto Vittori. Crew of the Space Station are Russian Space Agency astronauts Dmitri Kondratev (commander), Andrey Borisenko, Aleksandr Samokutyaev, NASA astronauts Cady Coleman and Ron Garan, and ESA astronaut Paolo Nespoli. Nespoli and Vittori are both Italian, and Vittori is the first Italian astronaut to make three flights. The first Italian astronaut was Franco Malerba, in 1992 (although 1960s American astronaut Michael Collins was born in Rome).


During late March to late April, the US Air Force's AEHF 1 communications satellite raised its orbital period from 23 hours to 25 hours, passing briefly through the geosynchronous range. AEHF 1 was launched in 2010 Aug to a supersynchronous transfer orbit of 249 x 50019 km x 22 deg; after failure of its main propulsion system, electric thrusters have been used to slowly raise the orbit to its current 22923 x 51539 km x 7.1 deg. Once the perigee has been raised to the 35780 km or so needed for geostationary orbit, the apogee will be lowered to match and the satellite will return to geosynchronicity.


The fourth Meridian communications satellite was launched on May 4 into a 978 x 39734 km x 62.8 deg orbit. The Meridian system provides communications for the Russian Defense Ministry, and replaces the older Molniya satellites.

Space-Based Infrared System

The US Air Force's SBIRS GEO-1 missile early warning satellite was launched on May 7. This is the first dedicated satellite in the Space-Based Infrared System, which will be the successor to the Defense Support Program satellites in operation since 1970. In addition to GEO-1, two National Reconnaissance Office satellites in highly elliptical orbit, USA 184 and USA 200, carry the SBIRS HEO-1 and SBIRS HEO-2 payloads in addition to their main NRO signals intelligence payloads.

GEO-1 carries an infrared telescope with a large focal plane infrared array to monitor large areas of the Earth at once. An internal movable mirror is used to scan the field of view across the visible disk of the Earth looking for possible missile launches. This is in contrast to the older spinning DSP satellites, whose telescopes were canted at an angle to the spin axis so that the motion of the entire satellite swept the field of view around. 23 DSP satellites were launched between 1970 and 2007.

GEO-1 was inserted into geostationary transfer orbit and will use its own on board propulsion to circularize its orbit. The spacecraft is based on the Lockheed Martin A2100 bus and uses a Leros-1 apogee thruster from the UK company AMPAC (Thanks to Ted Molczan for pointing out the Aviation Week story confirming the identity of the thruster.)

Suborbital launches

The Chinese Space Science and Applications Research Center launched its first Tianying-3C sounding rocket from Hainan Island on May 6. The rocket carried experiments to study electron density and electric fields in the ionosphere. Tianying-3C appears to be a single-stage solid rocket roughly comparable to the Japanese S-310.
