| Loral May Cancel H-2A Launch Contracts |
April
25
|
||
| Space
Systems/Loral is likely to cancel the remaining launches it contracted
in 1996 with Rocket
System Corp. to loft commercial satellites on its H-2A launcher.
Due to the sharp drop in launch prices, the pricing conditions of the
6-year old contract are no longer attractive and SS/L might cancel the
contract even if it has to pay a penalty fee. However, according to the
Yomiuri
Shimbun daily newspaper, RSC plans to try to salvage the deal by offering
a major discount. Eight launches were planned under this bulk procurement
contract but no firm payload was ever assigned to any of them. This cancellation
would leave RSC with only one firm launch contract, with Japan's Ministry
of Land, Infrastructure & Transport (MoLIT), to launch its MT-Sat 1R
meteorology and air-traffic control satellite in 2003. Editor's note: RSC landed two contracts in 1996 with Hughes Space & Communications (now Boeing Satellite Systems) and SS/L, for ten launches each. |

Following two consecutive launch failures of the H-2, the predecessor of the H-2A, in February 1998 and November 1999, Hughes cancelled its contract at no cost in July 2000 and recovered the US$36 million it had already paid. SS/L got a US$7.5-million refund in December 2000 when it cancelled two of its ten launch reservations. |

| Looking for a Launcher for Atlantic Bird 1 |
April
12
|
||
| Italy's Alenia Spazio is reportedly looking for a replacement launch opportunity for the Atlantic Bird 1 satellite it built for Eutelsat. Atlantic Bird 1, a 2,600-kg communication satellite ordered in 1999 for an in-orbit delivery, was initially due for launch atop a China Great Wall Industry Corp. Chang Zheng 3A (CZ-3A "Long March") vehicle, provided that Alenia could secure the necessary export licenses. The launch, initially due for mid-2001, has now slipped for more than one year. Launch options reportedly under consideration include the maiden flights of Arianespace's Ariane 5ECA or that of Boeing's new Delta 4 vehicle, both in the third quarter. | ![]() CZ-3A, Ariane 5 and Delta 4 (CGWIC/Arianespace/Boeing) |

| Atlas 5 and Delta 4 Get FAA Licenses |
April
3
|
||
| The U.S. Federal Aviation Administration (FAA) issued licenses to Lockheed Martin and Boeing for their respective Atlas 5 and Delta 4 launch vehicles, both due for maiden flight in July. Boeing's license covers Delta 4M and 4M+ launches to low inclination orbits from Cape Canaveral. Additional licenses will be needed for Delta 4H launches as well as for launches from Vandenberg AFB, California, and to high-inclination orbits. Lockheed Martin's license covers only the initial Atlas 5/401 version. Lockheed Martin is expected to apply for licenses to launch other versions as well as for launches to high-inclination orbits from Vandenberg although it has no firm plan yet to develop a launch capacity from there. | |||

| Titan 4 Launch Delayed |
April
25
|
||
|
The U.S. Air Force Space & Missile Systems Center has decided to postpone the launch of its next Lockheed Martin Titan 4B vehicle due to an unspecified problem with its classified payload for the U.S. National Reconnaissance Office, presumably a geostationary signal intelligence satellite. The launch was due on June 3 and could slip for more than a few days. The Titan 4B vehicle, in a 401B configuration with a Centaur cryogenic upper stage, is sitting on its pad at Cape Canaveral's SLC-40 launch complex. |

| EELV Launches Slipped |
April
22
|
||
| Some
40% of the launches ordered to Boeing
and Lockheed Martin
under the Evolved
Expendable Launch Vehicle
procurement have slipped beyond 2007 due to delays in the deployment of
satellite systems. Launches initially planned by 2007 are now planned
in 2007-2012. Among the delayed programs are the Block 2F version of the
Global
Positioning System (GPS-2F), the Defense
Meteorological Satellite Program (DMSP), the Wideband
Gapfiller Satellites (WGS), the geostationary Space-Based
Infrared System (SBIRS-High) and the Tri-Service Experiments (TSX)
planned under U.S. Air
Force Research Laboratory's Space
Test Program. Nevertheless, further EELV launches could be ordered
in 2002. Editor's note: Most of these missions have been delayed by the very good performance of satellites already in orbit, exceeding their planned lifetime and thus not needing replacement. |

|
|
A
long-delayed Lockheed
Martin Titan 23G vehicle was eventually defuelled and destacked
from SLC-4W in Vandenberg
AFB, California, to make room for another similar vehicle due to loft
a polar meteorological satellite on behalf of the U.S.
National Oceanic & Atmospheric Administration on June 24.
No operational Titan 23G was ever destacked and defuelled on the pad. Editor's note: Each of the Titan 23G vehicles, actually refurbished decommissioned Titan 2 intercontinental ballistic missiles, is configured for a specific payload. The Titan 23G G-9 vehicle, nicknamed "Cindy Mary", was initially stacked in late 2000 for the launch of the US$193-million DMSP-5D3-F16 Defense Meteorological Satellite Program spacecraft. The mission has been postponed continuously since two failed launch attempts on January 20 and 21, 2001 with the latest glitch - a leaky valve on an hydrazine thruster - forcing to remove the Lockheed Martin-built satellite and return it to the factory for repair. This launch is now scheduled in October. |

| NASDA Plans New H-2A Version |
April
17
|
||
| Japan's
National Space Development
Agency has formally approved the development of a new version of its
H-2A launch vehicle. The H-2A/204 would reuse the H-2A's
two-stage cryogenic core vehicle with some structural reinforcement on
the first stage to accommodate four 60-ton SRB-A solid strap-on
boosters. This version will be able to loft up to 6,000-kg of payload
to geostationary transfer orbit for a target launch cost of US$75 million.
It will be introduced in 2004 with the launch of the 5,800-kg ETS-8
engineering test satellite. Editor's note: The H-2A is currently available in three versions depending on the number of strap-on boosters: 202 (2 SRB-As), 2022 (2 SRB-As and 2 Castor 4As) and 2024 (2 SRB-As and 4 Castor 4As). |
![]() H-2A/202, 2022, 2024 and 204 (NASDA) |

The 2022 version will fly in 2003 to launch the MT-Sat 1R meteorology and air-traffic control satellite for Japan's Ministry of Land, Infrastructure & Transport (MoLIT). A 212 version with a large Liquid Rocket Booster (actually a first stage with two LE-7A engines) is also under study to increase the payload capability to 7,500 kg to geoastationary transfer orbit but it could be replaced by an evolution of the 204 version with a widebody first stage (see April 6 for detail). A formal decision between the two concepts is expected in June. |

|
||
|
|
Lockheed
Martin Astronautics has rolled out the last of its Titan vehicles,
a Titan 4B vehicle due to loft a classified U.S.
Air Force payload from Cape Canaveral in 2003. The Titan production
line in Littleton, Colorado, near Denver, will be modified to support
the new Atlas 5 family of launchers. Editor's note: Over 350 Titan vehicles have been launched since the very first Titan 1 intercontinental ballistic missile in February 1959. Among these, 212 Titan vehicles have been flown on space missions including 20 Titan 2s, 137 Titan 3s, 15 Titan 34s, 4 Commercial Titan and 36 Titan 4s. Three refurbished Titan 2 missiles are still due for launch in 2002-2003, as well as 4 Titan 4Bs. The Titan 4 series will be replaced by Boeing's new Delta 4H vehicle for the launch of very large payloads to low-Earth or geostationary orbits. |

|
Japan's H-2A launch vehicle could serve as a backup launch system
to Europe's Ariane 5 for the launch of Galileo
global navigation satellites according to Arianespace
officials. Arianespace is bidding together with Starsem
to provide launch services for the 30-satellite constellation with a mix
of Ariane 5ECB and Soyuz/ST vehicles. Editor's note: Under an agreement currently negotiated between Arianespace, ESA, CNES and the National Space Development Agency of Japan, a mutual backup between Ariane 5 and the H-2A is proposed for European and Japanese institutional payloads. |

|
||
![]() Delta 4H (Boeing) |
The
U.S. Air Force's
Space &
Missile Systems Center has officially assigned a U.S.
National Reconnaissance Office payload to the third flight of Boeing's
Delta 4H heavy-lift launch vehicle. The classified payload,
presumably a large geostationary signal intelligence satellite, will be
launched from Cape
Canaveral Air Force Station's SLC-37 in 2004. Editor's note: In October 1998, Boeing was contracted for an initial batch of 19 Delta 4 missions, including two Delta 4H flights, under the Evolved Expendable Launch Vehicle program. The first one was assigned to the launch of the DSP-23 early warning satellite. The NRO payload will fly the second heavy-lifter. In addition to these two missions, the U.S. Air Force agreed in December 2000 to pay Boeing US$141 million for an initial demonstration flight in early 2003. |

| U.S. Air Force Studies EELV Upper Stage Disposal |
April
8
|
||
|
The U.S. Air Force
and The Aerospace
Corp. are studying options to remove spent upper stages of Lockheed
Martin's Atlas 5 and Boeing's
Delta 4 launchers from operational orbits after direct injections
of payloads. The two launchers, developed under the Evolved
Expendable Launch Vehicle program, will be used to deliver some
payloads directly onto high altitude orbits - like the Navstar
satellites for the Global Positioning System - without need for the
apogee kick motors used with previous launchers. This will result in large
spent stages travelling for decades (or even centuries) on the same orbit
as their payloads. Among the options considered are an extra burn of the
upper stages to move them into a "graveyard orbit" or an early
payload release with final orbit tuning performed with their onboard station-keeping
thrusters. The study will be completed within 6 months. Editor's note: The first launch of a Navstar satellite by an EELV is currently scheduled in 2005. |

| Alternate Design for Heavy H-2A |
April
6
|
||
| Japan's National Space Development Agency is considering an alternate widebody design for the heavy-lift versions of its new H-2A launch vehicle according to Japan Times. The proposed design would be based on a new 5-m-diameter version of the current 4-m-diameter H-2A first stage, carrying 50% more propellant and powered by two Mitsubishi Heavy Industries LE-7A engines instead of one, with four SRB-A solid strap-on boosters. This widebody H-2A, with a 6-ton payload capacity to geostationary transfer orbit, would replace the H-2A/212 version, with a standard first stage and a single strap-on Liquid Rocket Booster (LRB) derived from the first stage with two LE-7A engines, and two SRB-As. The new version would cost 10% less to develop. A formal decision between the two designs is due in June after deliberation within the Space Activities Commission. |
|
||
| Editor's note: The H-2A/212 is currently scheduled to perform a demonstration flight in 2005. Its main payload for future operational missions is the 15-ton H-2 Transfer Vehicle (HTV), an unmanned freighter for the International Space Station. A H-2A/222 version, with two LRBs was also planned as a future development. The new widebody design is likely to require major modification to the existing launch facilities in Tanegashima which were designed for the H-2A versions based on the 4-m-diameter core stage and LRBs. | |||

| Rascal Contractors Confirmed |
April
19
|
||
|
The U.S.
Defense Advanced Projects Agency confirms the award of six nine-month
study contracts for the Responsive
Access, Small Cargo & Affordable Launch
(Rascal) system. The objective of the Rascal study is to design
a two-stage vehicle able to loft 75-kg payloads to a 500-km-altitude
orbit for US$750,000 with a capability to launch from a conventional
runway 24 hours after the arrival of the payload. The concepts
must be based on a Reusable Launch Vehicle as booster stage and
an Expendable Rocket Vehicle as upper stage. Northrop
Grumman was awarded a US$1.9-million contract for a feasibility
study on its proposed concept, based on low-cost RLVs and ERVs with
high-powered, short-cycle propulsion systems. The study also includes
evaluation of the technologies required to stage the ERV and control
the RLV in the Earth's upper atmosphere. Orbital
Sciences Corp. will be in charge of the ERV development. Spath Engineering
will also be part of the team. Delta Velocity was also awarded
a contract, worth US$1.25 million, to study its own version of
Rascal, with a modified fighter aircraft as the RLV and a two-stage
ERV. Delta Velocity's team includes Allied
Aerospace Industries Inc. (A2I2), ATK
Tactical Systems, Athena
Technologies, CSA
Engineering, Advanced
Project Research Inc. (APRI) and NASA's
Dryden Flight Research
Center. The other awardees are

Pioneer Rocketplane
(with Scaled Composites,
Microcosm, Orbitec
and HMX), Space
Access (with APRI, Honeywell
and Microcosm) and Space
Launch Corp. (with Scaled
Composites).
Each received a contract worth US$1-2 million. Following the initial
feasibility study, two teams will be downselected in early 2003 for
a 12-month definition study and a single contractor will be picked in
early 2004 for actual development and test flight. |

(QRLV-2), from the Kodiak
Launch Complex in Narrow Point, Kodiak Island, Alaska. The QRLV-2
single-stage suborbital vehicle was made from the M56 second stage
of a decommissioned Minuteman 1 intercontinental ballistic missile
under U.S. Air Force's
2nd Sounding Rocket Program (SRP-2). The launch was conducted on behalf
of the U.S. Air
Force Space & Missile Systems Center's Rocket Systems Launch Program
(RSLP) and provided a realistic theater ballistic missile tracking target
for the Alaskan
Command's joint-service Northern
Edge 2002 Exercise. The launch also served as a test platform for
the U.S. Army Space & Missile Defense Command's experimental batteries. Editor's note: The QRLV-1 vehicle, also made from a M56A1 stage, was launched on March 22, 2001 from Kodiak in support of the Northern Edge 2001 Exercise. |
|

Raytheon, Northrop
Grumman, General Dynamics
and various smaller industrial contractors, national laboratories and
universities. The objective is to integrate a large number of missile
defense platforms and sensors into a layered defense system to intercept
incoming missiles during boost, midcourse and terminal phases of flight.
A tight schedule has been set as an initial capability is planned in
2004-2006. According to DoD estimates, the previously separate Airborne
Laser (ABL), Navy Area Theater Ballistic Missile Defense, National
Missile Defense, Navy Theater Wide, Space-Based Infrared System Low
(SBIRS-Low), and Theater
High-Altitude Area Defense (THAAD) programs would have cost a total
of US$59.1 billion to complete. Now the consolidated Ballistic

(ATVs), due for launch in September 2004, was christened "Jules Verne."
This proto-flight model is under construction in several parts of Europe.
Alenia Spazio is
currently buiding the vehicle's pressurized cargo carrier in Turin, Italy,
while Astrium
SAS is working on the avionics bay in Toulouse, France. Astrium GmbH
will begin the integration of the propulsion module in Bremen, Germany,
in July. Meanwhile, dynamic testing of the Structural and Thermal Model
is proceeding in ESA's ESTEC technical center in Noordwijk, The Netherlands,
and should be completed by June. The Electrical Test Model is in final
integration by Astrium in Toulouse and will be shipped to EADS
Launch Vehicles in Les Mureaux for functional testing. |

Editor's
note: The 20,750-kg ATV will deliver up to 6 tons of payload to
the ISS every 15 months as part of a barter agreement with NASA
to cover part of Europe's share of utilization cost. It will also carry
some 4,700 kg of propellant to reboost the station. Each ATV will
thus have the resupply and reboost capability of roughly three Russian
Progress vehicles. Arianespace
was contracted in 2000 to provide nine Ariane 5ESV launchers
for the ATVs.Backgrounder: EADS Launch Vehicles is prime contractor for the €597-million development phase while Astrium GmbH will be in charge of production of operational vehicles. A final production contract, for 8 vehicles, is expected by late 2002 or early 2003. EADS-LV is also developing the highly autonomous flight software. Other major partners in the program include Contraves Space for the structural parts, Fokker Space for the solar generators and Sodern for the rendezvous sensors. |

| X-38 Human Interface Terminated |
April

| NASA's Johnson Space Center has terminated an ongoing sollicitation regarding the development of a human interface for the X-38 Vehicle 201 demonstrator. Vehicle 201 was designed as a proto-flight model of a future Crew Return Vehicle for the International Space Station. It is tentatively due for unmanned reentry flight from orbit in 2003. | |||
| Atlantis Flight Delayed by Hydrogen Leak |
April
4
|
||
| Preparation for the launch of NASA's Space Shuttle Atlantis has been interrupted after a gaseous hydrogen leak was reported on the pad during fuelling operations of the vehicle's large External Tank. The leak was detected more than 8 hous before liftoff on a line used to evacuate boiling hydrogen from the tank during fuelling operations. The launch, on the STS-110 assembly mission to the International Space Station, has been postponed at least to April 7 and is likely to slip beyond that date while emergency repairs are underway on the pad. | |||

China's
third prototype Shenzhou manned spaceship successfully reentered
and landed in Inner Mongolia at 08:51Z, after 108 orbits. The service
module was jettisoned after deorbiting and destroyed during reentry.
The autonomous orbital module was released in orbit. It is expected
to perform several maneuvers and remain in operations for six to nine
months. Shenzhou 3 was launched by a CZ-2F vehicle on March 25. |

| Lockheed Martin Might Scrap U.S.-Built RD-180 Capability - Recent Update |
April
22
|
||
| Lockheed Martin is considering the option of putting the development of a U.S.-based production line for NPO Energomash's RD-180 engine on hold unless its completion becomes necessary for U.S. autonomous access to space. The production line has been prepared by Pratt&Whitney in its West Palm Beach facility since 1997 to cope with a U.S. Department of Defense requirement that any launcher procured through the Evolved Expendable Launch Vehicle program could be 100%-built in the United States. The Russian-built RD-180 is the power plant for the first stage of Lockheed Martin's Atlas 5 launcher. Lockheed Martin proposes to stockpile 7 or 8 engines in order to ensure a continuous launch capability during the two to three years needed to initiate a domestic production if the Russian supply becomes unavailable for any reason. This strategy would allow to save money from the required investments. The U.S. Air Force, which manages the EELV program, still considers that a domestic production line is necessary. | ![]() RD-180 (Energomash) |

Editor's note: EnergoMash is currently under contract with Lockheed Martin to deliver up to 101 engines for the Atlas 3 and 5 vehicles. Initially, under the EELV procurement, Lockheed Martin had to provide a 100%-U.S. production capability for the Atlas 5 vehicle as soon as the very first flight. Over the years, this capability has been regularly postponed as the cost of a U.S.-built RD-180 appeared to be several times that of a Russian built engine. In 2000, the domestic production capability was announced in 2003. Recently, it was not planned before 2008/2010. The RD-180 is not the only part of the Atlas 5 to be built outside the United States. The 5.4-m-diameter payload fairings are supplied by Contraves Space in Switzerland and interstage adapters are built by EADS CASA Espacio in Spain. |

| Atlas 5 SRM Test Marred by Burn-Through |
April
15
|
||
|
The
failure of the first qualification static firing of a 40-ton solid rocket
motor developed by GenCorp
Aerojet to serve as strap-on booster for Lockheed
Martin's Atlas 5 series of launchers, on March 15, was
caused by a burn-through according to an independent review. The burn-through
appeared in a O-ring seal at the base of the motor's fixed nozzle. The
joint presumably failed 30 sec. into the 95-sec. firing, as a consequence
of the low temperature at start-up (4°C) which was one of the test
objectives. Due to this failure, this qualification test, the first of
two, will have to be repeated. According to Lockheed Martin officials,
this will not result in any delay for the first flight of an Atlas 5
with strap-on boosters as a 6-month margin had been planned between the
qualification of the motor and its first flight. However, this margin
will be reduced to 3 months. First
flight of an Atlas 5 version with strap-on boosters is due in February
2003. Editor's note: | |||
