The Zenit/Resurs story could get to be interesting...

[EXCERPT]
This month, the small satellite Safir is to be launched into
a low Earth orbit as a piggy-back of Russia's Resource O
satellite. It is equipped with a Rockwell/Autonetics GPS receiver
and will be used for environmental measurements.
Safir is the first of a series of six small satellites designed
and built under contract to Germany's Dara space agency by OHB
System GmbH. in Bremen.

[EXCERPT]
Bremen's OHB Systems has a two-satellite project with the
Russians: Safir R will be launched in March 1993 on the Resource
satellite atop a Zenith; and Safir I, which will be launched one
year later, also on Zenith. Carlo Gavazzi Space of Milan is a
partner.
From these and other sources, it looks as if there will indeed be
a Zenit launch carrying a German store-dump system as a companion to
the Russian main payload, reported to be called Resource Resurs O. The
designation "Resource O" is something of a puzzle, because this name
has been applied to other satellites which are much too small to
require the lifting capacity of the Zenit. On the other hand, the
Soviets, just before they transmuted into CISers, were apparently
upgrading their remote sensing capabilities. In Nicholas Johnson's
words:
Soviet Year in Space, 1990
by Nicholas Johnson
Teledyne Brown, Colorado Springs
[EXCERPTS AND PARAPHRASE]
During the late 1980's the Soviet Union created the Resurs
system divided into three major parts: Resurs-F, Resurs-O, and
Okean-O. Resurs-F refers to the short-duration photographic
reconnaissance satellites... Resurs-O, roughly analogous to the
U.S. landsat system, relies on multi-spectral data digitally
transmitted from sun-synchronous satellites launched by the more
than 30-year old SL-3 booster...
From an altitude of 600-650 km each 1,840 kg Resurs
spacecraft trains a 600-kg package of remote sensing instruments
on the oceans and land...
The manufacturers of Resurs-O, VNIIEM [in Istra, near
Moscow], are designing a more capable follow-on satellite for the
early 1990s. The new model may carry high-resolution optical
scanners (15-20 m resolution) and will operate from a higher
altitude near 800 km.
[Okean-O is an evolution of the Cosmos 1500 oceanographic
satellites, and is designated Platform-A by its builder, NPO
Yuzhnoye in Dnepropetrovsk, Ukraine. A significantly upgraded
version is due in the early 1990s]
[NPO Yuzhnoye] is already developing an entirely new platform
(platform B) for remote sensing devices, which will be launched
by the SL-16 booster into sun-synchronous orbits. The basic
platform is more than 10 m long and about 3 m wide and will carry
a greater payload mass than modified Okean-O... The overall
design will facilitate the installation of experimental sensors,
serving as a potential testbed for many programs. The first
flight of this vehicle is possible by 1992...
In potential competition with the new Yuzhnoye NPO design is
a similar concept being proposed by Yu.P. Semenov's NPO. Like
Platform B, this remote sensing spacecraft will employ the SL-16
booster to place it in a 400-km, 98 deg inclination orbit.
[An NPO Yuzhnoye fact sheet puts Platform B at 670 km.]
So. From the above information, it is obvious that the upcoming
Zenit launch will carry:
1. A _much_ upgraded Resurs-O satellite from VNIIEM, or
2. Platform B from NPO Yuzhnoye (making it an all-Ukrainian
mission, BTW, since the Zenit is also made my Yuzhnoye), or
3. NPO Energiya's satellite, or
4. Something else.
Such are the rewards of research. Sigh. I wonder if some
net.freund.de might check with the people at OHB Systems in Bremen to
see if they can provide any more information on the main payload, or
at least what the orbit is going to be?

Subject: Ukraine asks West to cooperate on space
Date: Tue, 15 Mar 94 11:00:30 PST
KIEV, March 15 (Reuter) - The head of Ukraine's space agency
appealed to the West on Tuesday to open the doors for full cooperation
on space research and construction in order to save its aeronautics
industry from collapse.
Volodymyr Gorbulin said Ukrainian space officials were
disappointed that officials from the U.S. National Aeronautics and
Space Administration (NASA) were refusing to discuss joint
construction at talks scheduled for next week in Kiev.
He told a news conference the U.S. officials had ruled out
discussions because Ukraine had not yet signed international
agreements on proliferation of advanced rocket technology.
``This issue (construction) is the one we were primarily
interested in and has been excluded from the agenda of our meeting
with U.S. authorities,'' Gorbulin said.
He said Ukraine's economic collapse had prompted 3,000
aerospace specialists to leave the country, where most of the former
Soviet Union's booster rockets were produced.
``They simply had too little to do,'' he said. ``Because of
illusions during the first year of independence, we lost time and we
were left out of the mainstream of the world space industry.''
Ukraine still produces the powerful ``Zenit'' launcher but
has been prevented from starting up a viable international business
because of a lack of appropriate legislation.
Kiev emerged from months of international isolation in
January when its parliament removed conditions it attached to the
ratification of the START-1 disarmament treaty.
Many of the 176 strategic nuclear missiles still deployed in
Ukraine were also produced in the former Soviet republic.

Subject: New Russian Earth Resources Satellite

Organization: NETCOM On-line Communication Services (408 241-9760 guest)
An interesting Russian space event seems to be coming up.
>From AWST, 14 March 1994, p.81
"The first prototype Safir [German minicomsat] will be launched
mounted to a Russian Resource Earth imaging satellite that is to be
orbited this May or June by a Ukrainian produced Zenith [SL-16] rocket."
Two things about this are noteworthy:
- This will be the first non-military operational flight of Zenit, which
to date has only been used to orbit heavy ELINT satellites of the
Cosmos 1603 class.
- The Resurs satellite mentioned may the totally new design described by the
Soviets a few years ago and which appeared in Nick Johnson's Soviet Year in
Space, 1989, pp. 50 & 60. It will carry a wide variety of instruments
including radar, visible light cameras, IR and microwave radiometers, etc.
This platform, like the Zenit, appears to be a product of NPO Yuzhnoye
in Dnepropetrovsk, making this an all-Ukrainian flight (except for the
German satellite and Russian RD-170 engine, of course).
Resurs should be a good target for satellite watchers, as its basic
dimensions are 3x10 meters, plus solar panels.

Subj: Zenit-2 Launches Photoreconnaissance Satellite
The Russian launch of Cosmos 2290 at midday GMT on August 26th appears
to be introducing a new generation of photoreconnaissance satellite to
the Russian space programme.
The Cosmos was launched using a Zenit-2 vehicle into a 64.81 degrees,
89.55 minutes, 212-293 km orbit. The satellite's orbit began the
process of slow decay until September 5, by which time it was in a
208-280 km orbit. During September 5-6 the satellite raised its
orbit to 209-348 km - the first satellite launched on a Zenit to
display a manoeuvre capability.
The introduction of the Zenit to the photoreconnaissance satellite
programme has been long-predicted and the vehicle's payload capability
of 13-14 tonnes to low Earth orbit will permit a satellite with a
similar mass to the US Big Bird and KH-11 satellites to be launched.
All previous Russian photoreconnaissance satellites have used the
Vostok and Soyuz launch vehicles.
It is tempting to draw a parallel between Cosmos 2290 the three
flights in 1986-1987, also launched into low orbits at 64.8 degrees:
Cosmos 1767, Cosmos 1820 and Cosmos 1873. Such a parallel might be
dangerous because of the launch time difference (08.20-08.30 GMT
compared with midday for Cosmos 2290) and the lower altitude regimes
of the three earlier satellites. The 1986-1987 flights apparently
did nothing but decay from orbit. It is, of course, possible that
these were failed missions and budgetary cutbacks have meant that it
has taken seven years to fly an improved version of the payload.
