TEL AVIV --
Issues of workmanship and quality control appear to have caused the loss of Israel's newest spy satellite, the Ofeq-6,
which crashed into the Mediterranean Sea during a failed attempt Sept. 6 to insert the
spacecraft into low Earth orbit.
Although
definitive findings of the failure investigation are not expected for several
weeks, preliminary data points to a defective electronic component attached to the satellite that
prevented the third stage of the locally produced Shavit
launcher from igniting. Government-owned Israel Aircraft Industries Ltd. (IAI)
of Lod is prime contractor for the Shavit launcher as well as the Ofeq
series of spy satellites.
The
incident marked the second time in less than six years that Israel has lost an expensive strategic
intelligence satellite during launch and comes on the heels of an unsuccessful
Aug. 26 attempt by the Israeli-developed Arrow-2 missile interceptor -- also
produced by IAI -- to destroy a simulated Scud D missile in flight.
In a Sept.
8 interview, Doron Suslik,
deputy vice president for corporate communications at IAI, insisted there was
no connection between the Arrow and Shavit malfunctions. He said IAI's management is
fully committed to determining the precise cause of the Ofeq-6 launch failure
and drawing appropriate conclusions from the event.
In addition
to the loss of nearly three years of development and production work costing up to $100 million, the failure dealt a severe blow to national prestige at a
time when Israel and Iran are involved in an increasingly vitriolic face-off
over the Islamic Republic's alleged program to deploy weapons of mass destruction.
Imagery
from Ofeq-6 was intended to supplement coverage by the in-orbit Ofeq-5, which Israel's security establishment relies on
to monitor movements of troops and missile launchers as well as activities
associated with nuclear development efforts in Iran and other countries. Israel's Ministry of Defense (MoD) also has exclusive access to Mideast coverage provided by the commercial Eros-A remote sensing satellite, also built by IAI.
Ephraim Sneh, a former deputy defense minister who now heads the
Israeli parliament's Defense Planning Subcommittee, decried the accident as a blow to Israel's intelligence-gathering
capabilities, particularly at a time when Iran appears to be moving forward with nonconventional weapon development efforts. "The damage in
terms of money, intelligence and prestige caused by this malfunction is simply
unacceptable," Sneh said Sept. 8 through a spokesman.
If the
failure investigation confirms suspicions that faulty workmanship and quality control rather than
design flaws are to blame, defense and industry officials here say Israel's MoD will seek
emergency funding to rush production and launch of a replacement satellite by
the end of 2006.
"We're all
waiting for the investigative committee to determine precisely what happened,
because we don't want to repeat the same mistakes and have the new satellite
fall again into the sea," retired major general Isaac Ben-Israel, former
director of Israeli defense research and development, said in an interview.
The new satellite, which Israel's financial daily Globes
dubbed the Ofeq-6.5 in its Sept. 7 editions, would duplicate the intended
capabilities of Ofeq-6. Resolution associated with Israel's military imaging satellites
remains classified, although sources here say the Ofeq-6 incrementally improves
upon capabilities now provided by the Ofeq-5 launched in May 2002. According to
government and industry sources, Ofeq-5 is capable of capturing panchromatic,
or black and white, images sharp enough to distinguish objects less than 1 meter across.
Prior to the launch failure, Israel's multiyear
satellite deployment plan called for completion of Ofeq-7 -- a generational
improvement over Ofeq-6 -- by 2008. In parallel, Israel's MoD had
planned to launch a synthetic aperture radar satellite, dubbed TechSAR, by 2006, along with a dedicated
geostationary-orbiting communications
satellite around 2007.
In
interviews, defense and industry officials here said it is still unclear how
replacing Ofeq-6 would affect the MoD's space launch roadmap. "At the
present time, it is way too premature to assess the effects of the launch failure
on future launch plans," MoD spokeswoman Rachel Naidek-Ashkenazi said.
Ben-Israel
noted that Ofeq-7, part of the MoD's current program,
represents "a quantum leap in capabilities" over the Ofeq-6, and therefore
entails much more risk. He surmised that Ofeq-7 may have to be delayed to
accommodate a replacement satellite launch. "There is some logic in saying that
we'll have to modify the program and add -- between Ofeq-6 and Ofeq-7 --
something which will play the same role as Ofeq-6," Ben-Israel said.
Replacing an already developed satellite likely would cost between $50 million and $100 million since the MoD would not have to bear any nonrecurring development costs, Ben-Israel said. As
for when IAI and Israel's defense establishment would be
ready to launch an Ofeq-6 replacement, Ben-Israel said 2006 is certainly
feasible, provided the MoD receives the requisite funding.
"Again, it's
all a matter of funding. And whether MoD will receive
replacement funding depends on the findings of the ongoing investigation," he
said.
In a statement immediately following the launch, Israel's MoD attributed the failure to a malfunction in the third
stage of the rocket. But subsequent analysis by government and industry experts appears to absolve
the third stage motor, which is actually attached to the satellite rather than
to the Shavit launcher itself. Instead, these experts
blamed one of four electronic triggering devices responsible
for igniting the motor.
Israel
Military Industries of Ramat Hasharon
builds the first two stages of the Shavit while Rafael
Armament Development Authority Ltd. of Haifa produces the third stage motor.
Telemetry
data indicates that the mission went as planned through separation of the
satellite and the attached third-stage motor. At that point,
however, the launcher's
flight control mechanism recognized a malfunction and refused to
allow ignition of the motor, sources
here said.
Aby Har-Even, managing director of the Israel Space Agency and
a former IAI program manager for the Shavit system,
credited control system for assessing the malfunction and preventing ignition
of the third stage.
"Listen, there's no getting around
the fact that this was a disappointing failure. But if you look on the bright
side, at least we know that the internal control mechanism was functioning
properly. It sensed that conditions -- whether they pertained to velocity,
pitch, attitude in space or other parameters -- were not nominal and refused to
ignite the third stage. Otherwise, it could have reached a bad orbit or fallen
in a place where it would be dangerous to fall, either on our own population
centers or in enemy territory," Har-Even said in a Sept. 8 interview.
Meanwhile, executives at ImageSat International, the Tel Aviv-based owner and
operator of the Eros series of commercial imaging satellites, said possible MoD plans to
expedite launch of a replacement for Ofeq-6 will have no bearing on their own plans to launch
Eros-B.
"The failed Ofeq-6 launch will not
have an impact on the Eros-B production schedule," Menashe
Broder, ImageSat chief
executive officer, said in an interview. "Regardless of the Israeli MoD's
plans to produce a replacement satellite, ImageSat
has a firm commitment to our customers to launch Eros-B during the first
quarter of 2006, and we and our manufacturers stand behind that date."
Eros-B, like the Eros-A satellite
launched in December 2000, will ride a Russian Start-1 rocket to orbit rather than the Shavit used to loft the Israeli military's Ofeq satellites.
