Iran
Orbits Third SatelliteIran performed its
fourth Earth orbiting satellite attempt using its Safir launch vehicle on February 3,
2012. The home-built Navid-e Elm-o Sanat satellite, fitted with an imaging payload,
reportedly weighed 50 kg. Safir lifted off from the Dasht-e-Kavir
desert southeast of Semnan, Iran at about 00:04 UTC and boosted
Navid-e Elm-o Sanat into a 375 x 276 km x 56 deg orbit.
Iran launched its first
satellite, Omid (Hope), in 2009, which made it the ninth country to join the
"Space Club". A second success occurred in 2011 when a Safir orbited the
Rassad satellite.
The successes followed an initial Safir launch failure in 2008.
Iran's Safir launcher is believed to have been derived
from Iran's Shahab ("Shooting Star") 3 intermediate range ballistic missile
(IRBM) series, itself thought to have been based on North Korea's No Dong missile.
The road-mobile rocket is erected by a transporter-erector next to a
retractable umbilical tower on a flat pad. The tower, which is retracted shortly
before launch, is used to fuel the rocket and to provide arming access to the vehicle and
payload. Launches are aimed toward the southeast, toward the Arabian Sea.
Soyuz U Orbits
Progress M-14M
Russia's Soyuz U launched Progress M-14M, loaded with
2.66 tonnes of cargo for the International Space Station (ISS), from Baikonur Space Center
in Kazakhstan on January 25, 2012. The 3-stage rocket lifted off from Area 1 Pad 5
at 23:06 UTC.
It was the first of five Progress cargo flights planned
for 2012.
 Delta 4 Lifts MilComSat WGS-4
Delta 358, a Delta 4M+5,4 consisting of a common booster
core augmented by four solid rocket motors, a five meter diameter Delta cryogenic second
stage (DCSS), and a five meter diameter payload fairing, boosted Wideband Global SATCOM
No. 4 into supersynchronous transfer orbit from Cape Canaveral Florida on January 20,
2012. The 66.3 meter tall orange and white rocket lifted off from Space Launch
Complex 37B at 00:38 UTC. DCSS performed two burns to push the 5.988 tonne Boeing
built satellite into a 439 x 66,872 km x 24 deg transfer orbit during the 40 minute 47
second long mission.
WGS-4 will provide 500 MHz range, X-band,
and 1 GHz range (Ka-band) communication links for the Pentagon. It can support up to
3.6 Gbps data transmission rates.
It was the 18th Delta 4 mission, but only
the second flight of a Delta 4M+5,4 variant, the only single-core version that flies a
five-meter DCSS. The RL10-powered DCSS is under consideration for use as an interim
cryogenic propulsion stage for NASA's planned Space Launch System.
CZ-3A Launches Weather Satellite
China's CZ-3A successfully launched
Fengyun 2-07, a weather satellite, from Xichang Satellite Launch Center on January 13,
2012. Liftoff from LC3 occurred at 00:56 UTC. The rocket's liquid hydrogen
fueled third stage performed two burns to insert the satellite into a 224 x 35,941 km x
24.3 deg geosynchronous transfer orbit. Spacecraft separation occurred 28 minutes
after liftoff.
It was the 23rd CZ-3A launch, performed by
CZ-3A tail number Y22.
China Orbits
Mapping Satellite
A CZ-4B orbited China's Ziyuan 3 remote sensing
satellite, along with a smaller VesselSat 2 satellite from Luxemburg, from the Taiyuan
Satellite Launch Center in northern Shanxi province. Liftoff occurred at 03:17
UTC.
The 2,650 kg primary satellite entered an approximate
500 km x 97.5 deg sun sychronous orbit about 12 minutes after it was launched.
VesselSat 2 entered a similar orbit.
Ziyuan 3 will provide information for
"land-resources surveys, natural-disaster prevention, agriculture development,
water-resources management, and urban planning", according to China news sources.
Soyuz
2-1a/Fregat Orbits Globalstar Sextet
Russia's R-7 launch system
barely missed a beat after a December 23 Soyuz 2-1b launch failure. On December 28,
2011, a Soyuz 2-1a/Fregat successfully orbited six second-generation Globalstar
communication satellites from Baikonur Cosmodrome.
The four stage rocket
lifted off from Area 31 Pad 6 at 17:09 UTC despite high winds, low clouds, and snow cover
to begin Starsem Mission ST-24. The three Soyuz stages boosted Fregat and its 4.2
tonne payload to suborbital velocity. Fregat fired once to enter a 210 x 923 km x
51.7 deg transfer orbit. It fired a second time about 50 minutes later to
circularize the orbit at 920 km x 52 deg, where the six satellites sequentially separated
in pairs. A final Fregat burn forced the depleted stage into a reentry trajectory.
Soyuz 2-1a uses an RD-0110
third stage engine, freeing it from the Soyuz 2-1b failure investigation since that
rocket's failure involved a third stage powered by an RD-0124 engine.
It was the 19th R-7 launch
of 2011, matching China's world-leading CZ family in launch numbers, but not in orbital
successes since two R-7 flights failed to reach orbit. The 19 flights were the most
in a calendar year for R-7 since 1993. ST-24 was the year's 84th orbital launch
attempt, and 78th success, world-wide - in both cases the most since 2000.
Soyuz 2-1b/Fregat Launch Fails
An attempt to launch a
Meridian communications satellite failed on December 23, 2011 when the third stage of a
Soyuz 2-1b/Fregat rocket faltered about seven minutes after launch from Russia's Plesetsk
Northern Cosmodrome - about two minutes before the vehicle would have reached orbital
velocity. The payload and Fregat upper stage, along with the rocket's third stage,
fell to earth in the "Ordynsky district of Novosibirsk territory" in Siberia,
according to Interfax.
Early investigation focused
on a potential third stage engine combustion chamber failure. An RD-0124 staged
combustion engine powers the Soyuz 2-1b third stage. Soyuz U, Soyuz FG, and Soyuz
2-1a rocket third stages are powered by a less powerful and efficient, but much more
proven, gas-generator cycle RD-0110 engine. It was the first failure of a Soyuz
2-1b/Fregat in seven attempts since the type started flying in 2006, including five
flights in 2011.
It was the 18th Soyuz
launch of 2011, and the second failure. The other incident occurred in August 2011
when a Soyuz-U third stage failed during a Progress freighter launch. Russia's
Proton and Rokot launch systems also each suffered one failure during the year.
China Orbits Observation Satellite
A Chang Zheng (Long March) 4B boosted Ziyuan I-02C, a
high-resolution remote-sensing satellite, into a 770 km sun synchronous orbit on December
22, 2011. The launch, from Taiyuan Satellite Launch Center in northern Shanxi
province, China, began from LC 2 at 03:26 UTC. The 2.1 tonne satellite separated
from the rocket's upper stage about 13 minutes later.
It was China's 19th orbital launch attempt, and 18th
orbital success, of 2011, moving China past United States annual launch numbers for the first time.
Ziyuan I-02C was developed and produced by the China
Academy of Space Technology, a subsidiary of China Aerospace Science and Technology
Corporation (CASC). It was the first satellite of its type.
Soyuz
TMA-03M Launch
A Russian Soyuz FG rocket successfully orbited three
cosmo/astronauts aboard the Soyuz TMA-03M spacecraft on December 21, 2011. Liftoff
from Baikonur Cosmodrome Area 1 Pad 5 occurred at 01:16 UTC, beginning a 9 minute ascent
to a 51.6 deg low earth orbit. The crew will join the International Space Station
(ISS) Expedition 30 crew, and will stay on board as part of a future Expedition 31 crew.
Soyuz TMA-03M will dock with ISS on December 23.
On board Soyuz TMA-03 were Russian cosmonaut Oleg
Kononenko, European Space Agency (ESA) astronaut André Kuipers, and NASA astronaut Don
Pettit. It was the seventh crewed space launch of 2011 world-wide, and the fourth by
Soyuz.
CZ-3B Orbits Nigerian Comsat
The 18th CZ-3B
orbited Nigeria's NigComSat 1R communications satellite from Xichang Satellite Launch
Center on December 19, 2011. China's most powerful GTO lifter rose from LC 2 at
16:40 UTC. The rocket's liquid hydrogen third stage fired twice during a 26 minute
mission to place the 5.15 tonne satellite, built by China Aerospace Science and
Technology Corporation China Space Technology Research Institute,
into a 203 x 42,007 km x 24.8 deg geosynchronous transfer orbit.
The satellite replaces
NigComSat 1, which failed in orbit in 2008 only about one year after its launch from
Xichang.
It was the 18th
Chang Zheng (Long March) flight of 2011, and the 17th success, more than any other launch
system in the world. CZ-3B uses a CZ-3A core augmented by four liquid strap on
boosters.
Soyuz Orbits Spysats from Kourou
The second Russian Soyuz
to fly from Kourou, French Guiana launched six military observation satellites on December 17,
2011. Liftoff of the Soyuz 2-1A/Fregat from the ELS pad took place at 02:03 UTC. The rocket, performing the
VS02 mission for Arianespace, flew a northbound trajectory toward sun synchronous low
earth orbit. Five of the satellites separated about one hour after liftoff into a
700 km orbit. These included one tonne Pleiades 1A, a French defense ministry
observation satellite, and four 120 kg ELISA (Electronic Intelligence by Satellite)
demonstrator satellites. ELISA test test methods for mapping radar transmitters for
France's Defense Procurement Agency.
The Fregat upper stage
maneuvered to a lower orbit before a sixth, 117 kg Chilian imaging satellite named Sistema
Satelital de Observación de la Tierra (SSOT) separated at 06:39 UTC.
Soyuz 2-1A/Fregat, called "Soyuz ST-A" by
Arianespace, differed from the Soyuz 2-1B/Fregat used for the initial VS01 launch from
Kouou in that it's Blok I third stage used an RD-0110 gas generator cycle engine rather
than an RD-0124 staged combustion cycle engine.
Arianespace
was the contracting authority for the mission. Russia's TsSKB Progress and NPO
Lavochkin built the rocket and performed launch and flight operations. Russia's
TsENKI performed launch operations.
H-2A Launches Japan Spysat
Japan's Information Gathering Satellite (IGS) Radar-3
was boosted to sun synchronous orbit by H-2A F-20 on December 12, 2011 from Yoshinobu
Launch Complex 1 at the Tanegashima Space Center. The 202 series rocket, boosted by
a pair of SRB-A solid motors, lifted off at 01:21 UTC.
It was the second H-2A launch, and third H-2A or B
launch, of 2011.
Proton Orbits
Comsat Pair
A Proton M/Briz M successfully boosted two communication
satellites into orbit from Baikonur Cosmodrome, Kazakhstan on December 11, 2011. The
pair included Russia's 1.15 tonne Luch 5A and Israel's 1.59 tonne Amos 5.
The 372nd Proton lifted off at at 1117 UTC. The
Briz M fourth stage fired once to reach a low earth parking orbit, then fired three more
times during the first 9 hours of the mission to place Luch 5A into a geosynchronous
transfer orbit with a high altitude perigee. The stage fired a fifth time to lift
Amos 5 into a near-geosynchronous orbit. Amos 5 separated about 9 hours 35 minutes
after liftoff.
The flight was conducted under Russian government
auspices from Baikonur's Area 81 Pad 24.
China Launches Navsat
China added to its navigation satellite constellation on
December 1, 2011 when a CZ-3A rocket orbited Beidou 10 (2-I5) from Xichang space
center. The three stage launch vehicle lifted off at 21:07 UTC from Pad 3. The
liquid hydrogen fueled upper stage performed two burns to boost Beidou into a 217 x 35,848
km × 55.06° inclined geosynchronous transfer orbit.
A basic Beidou system is now in orbit. China plans
to add to the network until 30 satellites are in orbit by 2020.
It was China's 17th orbital launch of the year, and the
16th success, most ever for China in a calendar year.
China Sets
Launch Mark
A Chang Zheng 2C rocket launch from Taiyuan Satellite
Launch Center on November 29, 2011 upped China's 2011 orbital attempt total to a new
calendar year record of 16. The rocket boosted YaoGan Weixing 13, a remote
sensing satellite, into a 505 x 510 km x 97.1 deg orbit after an 18:50 UTC liftoff from
Taiyuan's second pad.
Western analysts believe that the satellite is part of a
military reconnaissance network in which it may work in conjuction with another satellite
already in orbit.
One of China's earlier 2011 launches failed. As a
result, the CZ-2C launch only tied China's 2010 record of 15 orbital launch successes.
Soyuz
2-1B/Fregat Launches Glonass M
A Russian Soyuz 2-1B/Fregat orbited a Glonass M
navigation satellite on November 27, 2011. The four stage rocket flew from Site 43/4
at Plesetsk Cosmodrome in northern Russia, lifting off at 08:26 UTC. Fregat
performed three burns to insert Glonass M into a 19,300 km circular orbit. The 1,414
kg satellite separated at 12:03 UTC.
It was the fifth Glonass M satellite orbited during the
past two months, bringing Russia's total active Glonass constellation up to 30 satellites.
The flight was the 15th R-7 launch attempt of 2011 and the 74th orbital worldwide
attempt of the year, matching last year's total.
Atlas 5 Powers
Mars Science Laboratory
AV-028, an Atlas 5-541 with four strap
on solid motors and a five meter diameter payload fairing, successfully boosted NASA's
3.839 tonne Mars Science Laboratory (MSL) from Cape Canaveral, Florida toward Mars on
November 26, 2011. Liftoff from Space Launch Complex 41 occurred at 15:02 UTC.
MSL separated into solar orbit 44 minutes later, after the Centaur stage performed two
burns.
MSL carries the 0.9 tonne nuclear powered Curiosity
Rover, which is expected to begin exploring Mars surface after landing in August 2012.
It was the fifth Atlas 5 launch of 2011 and the 18th and final planned U.S. orbital launch
attempt of the year. AV-028 was the first flight of a "541" Atlas 5
variant.
Proton Boosts
AsiaSat 7
A Proton M/Briz M orbited AsiaSat 7, a 3.813 tonne
communications satellite, from Baikonur Cosmodrome on November 25, 2011. The big
four-stage rocket lifted off from Area 200/Pad 39 at 19:10 UTC to begin a 9 hour 13
minute, 4-burn Briz M mission that lifted AsiaSat 7 into a 13,814 x 35,586 km x 0 deg
targeted geostationary transfer orbit. The Space Systems/Loral 1300 series satellite
will provide television and VSAT services from 105.5 degrees east in the Clarke Belt.
It was the 371st Proton launch since 1965, and the 8th
Proton launch of 2011. The Khrunichev rocket has scored five successes since
suffering an August failure.
China Launches
Two Satellites
A two-stage CZ-2D orbited two satellites from Jiuquan
Satellite Launch Center in northwest China's Gansu Province on November 20, 2011.
Chuangxin 1-03 and Shiyan Satellite 4 were boosted into roughly 800 km x 98.4 deg sun
synchronous orbits after a 00:15 UTC liftoff, dawn local time, from SLS 4 Left.
Chuangxin 1-03, built by the Chinese Academy of
Sciences, is designed to collect water, hydrological and meteorological data. Shiyan
Satellite 4, developed by the Chinese Research Institute of Space Technology, carries
space technolgy experiments.
It was the 15th CZ-2D launch, and the 15th launch
attempt by China in 2011.
Soyuz Orbits ISS
Crew
A Soyuz FG successfully orbited Soyuz TMA-22 with three
crew bound for the International Space Station from Baikonur Cosmodrome on November 14,
2011. Anton Shkaplerov, Anatoliy Ivanishin, and Dan Burbank rode the 7.2 tonne
spacecraft into orbit after launching in a snowstorm from Area 1 Pad 5. It was the
first crewed launch since the Shuttle finale in July.
The Soyuz mission had been delayed for several weeks
while Russian teams worked, first to isolate the cause of an August Soyuz-U failure during
the Progress M-12M launch, and then to conduct a precursor unmanned Soyuz U flight with
Progress M-13M at the end of October to verify performance of the RD-0110 third stage
engine that failed in August.
If was the 20th launch attempt from Baikonur in 2011,
and the 70th world-wide during the year.
CZ-4B Orbits
Observation Satellite
A CZ-4B rocket launched China's Yaogan 12 earth
observation satellite, along with a microsatellite, into sun synchronous orbit on November
9, 2011. The three-stage launch vehicle lifted off from the second CZ pad at Taiyaun
space center China's northern Shanxi province at 0321 UTC. Yaogan 12 entered a 483 x
491 km x 97.4 deg orbit.
Western observers often speculate that Yaogan spacecraft
are used for military reconnaissance, but China says that they are used for
"scientific experiments", "surveys on land resources" estimates of
"crop yield and help with natural disaster-reduction and prevention."
Russia's Mars
Mission Falters
Russia's ambitious Phobos-Grunt mission faltered in low
Earth orbit on November 8, 2011, shortly after launch atop a two-stage Zenit 2SB rocket
from Baikonur Cosmodrome Site 45 Pad 1, Kazakhstan. Liftoff occurred at 20:16
UTC.
The Phobos-Grunt payload, which consisted of an orbiting
spacecraft, a lander intended to land on the Martian moon Phobos, a soil return
spacecraft, and an "MDU" propulsion unit similar to a Fregat SB stage, was
boosted into a 207 x 347 km x 51.6 deg parking orbit by the two-stage Zenit. The
entire vehicle, including rocket, MDU, and spacecraft, was identified as a "Zenit
2FG".
However, after coasting for 2.5 hours and more than 1.5
orbits, the MDU did not perform its planned first burn, which would have moved the
spacecraft into a 250 by 4,170 km orbit. Neither did a planned second burn occur
some 2 hours later to boost Phobos-Grunt out of Earth orbit toward Mars. The cause
of the problem was being studied on November 9. Still to be determined is if a
failure, if one occurred, would be assigned to the launch vehicle or spacecraft.
Proton Orbits
Navsat Triplet
A Proton M with a Briz M upper stage successfully placed
three Glonass-M (Uragan-M) navigation satellites into orbit after a November 4, 2011
launch from Baikonur Cosmodrome. Liftoff from Area 81 Pad 24 occurred at 12:51 UTC,
early daylight at Baikonur.
Briz M performed four burns during a nearly six-hour
mission to lift Glonass-M Nos. 43-45, totaling 4.245 tonnes combined, into circular 19,100
km orbits. The success helps offset a failed Glonass launch in December, 2010.
It was the 50th flight of the Proton M/Briz M
combination. Forty six of the flights, which began in 2001, have been successful.
Unmanned Shenzhou 8 Flies Toward Docking
China launched the Shenzhou 8 spacecraft on an unmanned
docking test flight from the Jiuquan space center on October 31, 2011. A Chang Zheng
(Long March) 2F rocket lifted off at 21:58 UTC to boost 8.08 tonne Shenzhou 8 into a
two-day chase orbit aimed toward a planned docking with the Tiangong 1 spacecraft launched
one month prior from the same site. The three-piece spacecraft was injected into a
200 x 330 km x 42.780 deg orbit.
If successful, the planned automatic docking and 17 day
mission will serve as a test for subsequent manned Shenzhou visits to Tiangong 1 next
year.
Soyuz U Returns
to Service
Russia's Soyuz U successfully orbited Progress M-13M,
loaded with 2.6 tonnes of cargo for the International Space Station (ISS) from Baikonur
Space Center in Kazakhstan on October 30, 2011. Liftoff from Area 1 Pad 5 took
place at 10:11 UTC.
It was the first Soyuz U launch since an identical
rocket failed during the Progress M-12M flight on August 24, 2011. That failure was
caused by an obstruction of kerosene fuel feed to the RD-0110 third stage engine gas
generator. Roscosmos subsequently examined available engines and determined that the
defect was an isolated case.
Thunder God
Finale
The last planned Thor-family Delta launched NASA's
National Polar-Orbiting Operational Environmental Satellite System (NPOESS) Preparatory
Project (NPP) mission into sun synchronous orbit from Vandenberg AFB Space Launch Complex
2 West on October 28, 2011. Liftoff occurred at 09:48 UTC. Delta's second stage
fired twice to place 1,970 kg NPP into a 824 km x 98 deg orbit during a 59 minute flight.
The second stage then performed two final burns (evasive and depletion), the final
planned work by the 54 year old Thor rocket family.
Delta 357 was a Delta 2-7920-10C with nine strap-on
motors on a two-stage core vehicle topped by a 10 foot diameter composite payload fairing.
It was the 151st and final planned Delta 2, the 340th Thor-family Delta, the 606th
Thor family orbital launch, and the 719th launch of any type by a Thor family rocket.
It was also the 96th consecutive Delta 2 success. The Thor family performed
more orbital launches than any other rocket in the world except for Russia's R-7.
Delta 2's retirement coincides with the end of NASA's Space Shuttle. The shut down
of the two systems, which together accounted for a majority of U.S. launches in recent
years, will slash future U.S. launch numbers.
Unassembled parts for up to five more unassigned Delta 2
vehicles exist, but their GEM-46 "Heavy" type solid motors cannot fly from SLC 2
West. Potential Delta 2 payloads require near polar orbits that require launch from
Vandenberg. GEM motor production would have to be restarted for any such launches.
United Launch Alliance has nonetheless said that it intends to offer Delta 2 in
competition for several NASA missions. Any launches, if purchased, won't occur for
several years at the earliest.
Ball Aerospace built NPP using a BCP2000 bus.
The satellite carries several new sensors originally developed for NPOESS, a
program subsequently restructured into the Joint Polar Satellite System (JPSS),
whose first satellite is scheduled in 2015.
Russian Rockets
Soar from Two Continents
Proton Launches ViaSat 1
In a span of less than two days, Russia's two busiest
orbital launch vehicles, Krunichev's Proton and TsSKB Progress's Soyuz, successfully
orbited western satellites from launch pads located on opposite sides of the planet.
The launches highlight the expanding reliance by Western countries on Russian space
launch hardware.
A Proton M/Briz M launched ViaSat 1 from Baikonur
Cosmodrome, Kazakhstan on October 19, 2011. The big hypergolic propellant rocket
lifted off from Area 200 Pad 39 at 18:48 UTC, beginning a 9+ hour mission that lifted the
6.74 tonne satellite into geosynchronous transfer orbit. ViaSat 1 was a Space
Systems/Loral 1300 series spacecraft built for ViaSat, Inc of Carlsbad, California.
It was the heaviest GEO satellite ever launched on a Proton and was the "highest
throughput" satellite yet launched with more than 140 Gbps data capacity, "more
than all satellites covering North America".
Soyuz
VS01 Launch
The Soyuz launch took place on October 21, 2011 from a
brand new launch pad at, for Soyuz, a brand new launch site. A Soyuz 2-1B/Fregat
launched two European Galileo navigation satellites from the new Soyuz Launch Complex
(ELS) at the Guiana Space Center (CSG) in French Guiana. The 3.5 stage rocket lifted
off at 10:30 UTC on a 3 hour, 49 minute, 27 second mission that featured two burns of the
Fregat upper stage to insert the satellite pair into 23,000 km x 54.7 deg orbits.
Astrium GmbH of Germany led the production team of
Galileo PFM and FM2, which together comprised the Galileo IOV-1 payload for the
Arianespace VS01 mission. Together the satellites totaled 1.4 tonnes mass.
Arianespace was the contracting authority for the mission.
Russia's TsSKB Progress and NPO Lavochkin built the rocket and performed launch and
flight operations. Russia's TsENKI performed launch operations.
The Soyuz Launch Complex at Kourou is similar to Soyuz sites at
Baikonur and Plesetsk, but features an additional vertical mobile service tower used to
vertically mate the payload to the rocket on the pad.
Korea and the United States also depend on
Russian launchers. Korea's KSLV uses a Russian Angara first stage. In the
U.S., Atlas 5 is powered by a Russian main engine, Taurus 2 uses a Russo-Ukranian first
stage, and NASA relies on Soyuz to launch its astronauts to the International Space
Station.
PSLV
Orbits Earth Observation Satellite
India's Polar Satellite Launch Vehicle, vehicle
PSLV-C18, orbited the Indo-French Megha-Tropiques satellite along with three
microsatellites from the first launch pad of Satish Dhawan Space Center, Sriharikota on
October 12, 2011. The combined 1,047 kg payload was inserted into an 865 km x 20 deg
orbit about 22 minutes after the 05:31 UTC liftoff.
Megha-Tropiques has a microwave imager, a microwave
sounder, an optical sensor, and a GPS occulation sounder. The instruments will
measure moisture profiles in the tropical atmosphere.
PSLV-C18 was the seventh flight of a
"core-alone", or PSLV-CA configuration without solid strap-on motors. It
was also the 18th successfull PSLV in 20 flights.
One of the microsatellites, named Vesselsat, will be
used by Orbcomm to test Automatic Ship Identification (AIS) systems for that company's
next-generation satellite constellation.
CZ-3B
Orbits W3C for Eutelsat
The 17th CZ-3B
orbited Europe's W3C communications satellite from Xichang Satellite Launch Center on
October 7, 2011. The 3.5 stage rocket, China's most powerful GTO launcher, lifted
off from LC 2 at 08:21 UTC in a rare daytime launch. The rocket's liquid hydrogen
third stage fired twice during a 25.7 minute mission to place the 5.4 tonne Thales Alenia
Space Spacebus 4000C3 satellite, built for Eutelsat, into a 206 x 35,973 km x 26.1 deg
geosynchronous transfer orbit. The Spacebus 4000 series is designed to be
"ITAR free" with no U.S. manufactured components, allowing it to be launched by
China.
It was the 12th
Chang Zheng (Long March) flight of 2011, more than any other launch system in the world.
It was also the 45th launch by the CZ-3A family of rockets. CZ-3B uses a
CZ-3A core augmented by four liquid strap on boosters.
The launch was
the year's 60th orbital attempt worldwide, and the 55th success.
Land Launch
Zenit Boosts Intelsat 18
-
- A Ukrainian/Russian Zenit 3SLB/DMSLB, flying for Land
Launch, successfully orbited Intelsat 18 from Baikonur Cosmodrome on October 5, 2011.
The three stage kerosene/liquid oxygen fueled rocket lifted off from Area 45 Pad 1
at 21:00 UTC. The 3.2 tonne Orbital Sciences Corporation Star 2.4E satellite
separated into geosynchronous transfer orbit about 6.5 hour later, after the Energia Blok
DM-SLB stage completed three burns.
Intelsat 18
will provide direct broadcast TV coverage and network services using Ku-band and C-band
transceivers.
The Blok DM-SLB stage fired once to boost itself and its
payload into a 182 x 692 km x 51.4 deg parking orbit. It fired a second time about 1
hour 20 minutes after liftoff to boost itself into a 198 x 35,832 km x 48.9 deg orbit.
The final burn raised the transfer orbit perigee to 5,517 km and reduced the
orbit's inclination to 19.5 deg.
It was the first Zenit Land Launch mission since 2009.
Two Zenit 2F vehicles with Fregat upper stages flew earlier this year. A Sea
Launch Zenit flew in September.
Soyuz
2-1B/Fregat Orbits Glonass M
A Russian Soyuz 2-1B with a Fregat upper stage
successfully orbited a Glonass M navigation satellite on October 2, 2011. The four
stage rocket lifted off from Plesetsk Cosmodrome in northern Russia at 20:15 UTC.
The Fregat stage fired three times to insert Glonass M into a 19,300 km circular
orbit. The 1,414 kg satellite separated at 23:47 UTC.
It was the first R-7 flight since an August 24, 2011
failure during the Progress M-12M launch attempt. Soyuz 2-1B, however, uses a more
advanced RD-0124 third stage engine. The Soyuz U version that failed had a faulty
RD-0110 engine system. Crewed launches by Soyuz will not resume until an RD-0110
flies a successful unmanned mission, possibly in late October.
Proton Orbits
QuetzSat 1 for SES
A Proton M/Briz M successfully orbited QuetzSat-1 for
SES of Luxembourg from Baikonur Cosmodrome on September 29, 2011. After an 18:32 UTC
liftoff from Area 200/Pad 39, the Briz M upper stage completed five burns during a 9 hour
13 minute mission to deliver the communications satellite to geosynchronous transfer
orbit. The 5,514 kg satellite was a Space Systems/Loral 1300 series platform.
It was the 368th Proton launch, 67 of which have been
for International Launch Services.
China Launches Tiangong 1
Docking Module (Updated 10/1/11)
China launched its 8.5 tonne Tiangong 1 spacecraft into
orbit from Jiuquan Satellite
Launch Center on September 29, 2011. The launch, by the first CZ-2FT1 rocket, began
at 13:16 UTC from the same SLS Right pad used for crewed Shenzhou launches. Tiangong
1 entered a 200 x 347 km x 42.76 deg orbit about 10 minutes after liftoff.
Tiangong 1 will serve as a docking target and multi-day orbiting
module for the unmanned Shenzhou 8 spacecraft later this year. If successful, the
spacecraft may serve the same purpose for crewed Shenzhou 9 and 10 spacecraft in 2012.
CZ-2FT1 is an improved CZ-2F that is equipped with longer strap-on
boosters that each carry nearly 3 tonnes more propellant than their predecessors.
The boosters burn for 155 seconds, about 18 seconds longer than the previous boosters,
allowing CZ-2FT1 to boost up to 8.6 tonnes to LEO. The rocket also uses a 12.7 x 4.2
meter payload fairing in place of the usual CZ-2F Shenzhou spacecraft and its launch
escape system.
NASA
Announces SLS Plans
After months of delays, NASA announced its Space Launch System plans
on September 14, 2011. Will NASA be able to afford the new system?
