It would be hard to image in today's economy that a business, say
a restaurant, would, before closing up for the night, have an employee
walk around and turn on all of the water faucets. Over the course of
each night thousands of gallons of water would gush down the drain -
all of it expensive, treated water - wasted.
It would also be hard to image a homeowner on a cold winter
morning carefully walking through their house, opening each window
before heading to work. During the course of the day the furnace
runs, burning cubic yards of natural gas - all of it an expensive
and not easily replaced natural resource - wasted.
It is not hard to image, even in today's economy, that the builder
of a new office building would not spend thousands of dollars to
install a lighting system to protect the parking lot of the building.
Each night, the lights turn on and stay lit until morning, even though
at three a.m. there is not an automobile to be seen. Nonetheless, the
lighting of the parking lot is accepted without question, even though
it costs hundreds if not more than one thousand dollars to operate the
lights.
It is not hard to image a homeowner going to a local hardware or
discount store. Worried about rising crime rates, the owner buys the
biggest and brightest all-night "security" light for $29.95. From dusk
until dawn, the faithful light "protects" their property - at the tune
of roughly seventy dollars each year. Nevertheless, the light is
accepted as an improvement, even though it does emit a lot of glare
and can be uncomfortable to live near.
While the first two scenarios sound outrageous, and certainly it
would be amazing to find a person who left their windows open during
the winter, the last two stories are accepted practice. Hundreds of
thousands of office buildings are lit at night. Millions of homes
have security lights hanging above their garages.
But in reality the differences are not so great. The vast
majority of security lighting used in the United States is incredibly
wasteful. David Crawford, Executive Director of the International
Dark-Sky Association (IDA), an organization that encourages quality
lighting, estimates that more than one billion dollars are wasted each
year in the United States. This amounts to staggering amounts of
fossil fuels that are burned for no use whatsoever.
"It's easy to estimate - and one of our handouts does it - we
spend way more than one billion dollars a year in the United States
alone, doing nothing except lighting the bottoms of birds. I think
that is intolerable," says Crawford.
If you own or rent a security light, take a minute to look at it.
Does the lamp - the part that actually produces the light - stick down
below the cover over the light? If it does, then you may be wasting
light - and money.
What we are talking about here is light pollution - the
unnecessary use of light. The root cause of light pollution is
decades of cheap electrical power combined with the natural human need
to feel safe at night. The effect is the destruction of the night sky
and the loss of an important part of our folklore, the historical
sense of who we are in this Universe. Another, more "down-to-Earth"
effect of light pollution is an incredible waste of money and natural
resources.
There are many different types of light pollution, from a downtown
building lit to attract attention to a $29.95 175-watt mercury vapor
security light that is sold at almost any hardware store. However,
any time light is allowed to escape - a word chosen carefully - into
the night sky, light pollution is the result. That escaped light
travels upwards in the atmosphere until at some point it is reflected
back toward the ground by tiny particles of dust floating in the air.
We see this as a brightening of the sky. Faint stars are overwhelmed
by the glow. From the country, our cities can be seen from 48 kilo-
meters (thirty miles) away by the glow that hovers above them.
Light pollution prevents people living in our cities from seeing
all but the brightest stars and planets. From the country, brightly
lit cities cause "skyglow," a term that astronomers use to describe
the brightening that occurs in the direction of a city. Inside the
city, children can spend their entire lives unaware of the Universe
around them. From the country, telescopes at observatories perform
at only a fraction of their true capability.
For years, astronomers have been locating their telescopes on
mountain summits that are more and more isolated in an effort to avoid
the lights of humanity. However, what happens when you run out of
mountains or you can no longer afford to build a new observatory? What
about the hundreds of thousands of amateur astronomers? What about
the millions of children who are deprived a very important part of
nature, a part of their own culture as well as a looking glass into
the past and future?
Light pollution is a true threat to astronomy. From the
professional end, telescopes cannot collect data as well as in the
past. Multi-billion dollar facilities - like the National Optical
Astronomy Observatory (NOAO) located on Kitt Peak in Arizona - are
becoming more and more useless as the sky gets brighter. In one
case, the Mount Wilson Observatory near Los Angeles, California,
the historic 250-centimeter (100-inch) Hooker telescope - the very
instrument used by Edwin Hubble to discover the expanding Universe -
has been shut down and put into mothballs after becoming useless for
many types of research because of light pollution.
In the cities, more and more of our youth never learn even the
basics about the sky. It is hard to become interested in astronomy
if all you can see are the Moon and a few bright stars and planets.
While many children do not grow up to become professional astronomers,
star gazing is more often than not a child's first introduction to
science. Who cannot remember that camping trip as a child when you
first discovered the thousands of stars that hang in the sky? Many of
the children who have such experiences often grow up to be scientists
of one sort or another.
While light pollution has been around since the early Twentieth
Century - if not before - today's climate of rising crime and
aggressive sales on the part of electric companies and lighting
manufacturers have caused light pollution to be worse than ever. For
all practical purposes, there is not one single spot in the United
States east of the Mississippi River than is not affected. From
satellite photographs it is possible to trace the Interstate Freeway
system across the country. Affluent amateur astronomers pack away
on "observing vacations" to dark sky locations on the highest Rocky
Mountains, Hawaii, Australia, and South America. Meanwhile, disadvan-
taged children are forced to retreat - if they are lucky enough - to
the dome of a planetarium to see what their ancestors took for granted.
There is a "dark spot" at the end of the tunnel, though. Things
are slowly turning around. IDA, under the direction of Crawford and
amateur astronomer Tim Hunter, are organizing various communities
involved in the fight against light pollution into a force to be
reckoned with. It is not too surprising that these communities
include more than just the astronomers.
"Professional lighting engineers know that there is a lot of
bad lighting out there," says Crawford in regard to IDA members who
light for a living. "We also have lighting companies, universities,
observatories, astronomy clubs, people from the general public who
have happened to hear about (light pollution) and are tired of their
neighbor's bad light or recognize that the sky up there used to be
okay and they are just tired of living in this junky nighttime
environment."
Others include environmentalists, naturalists who see overzealous
night time lighting affecting animal and plant populations, and
community planners who are interested in attracting people to their
communities with good lighting.
The primary focus of IDA's efforts is to encourage good lighting,
not the turning off of lights. "We don't want to turn the lights
off," Crawford says. "We advocate the use of better fixtures that put
the light were it's needed. That helps save the sky, saves money and
makes for a better night time environment."
Better lighting can be accomplished by any one or combinations of
several approaches:
* Shielding: Perhaps the easiest and most effective use of good
lighting. In the lingo of a lighting consultant, fixtures that do not
allow light to escape upward are called "full cutoff fixtures." This
approach is rooted in basic common sense: Put the light were you need
it. By reflecting all of the light toward the ground, a lower wattage
bulb or lamp can be used, saving the user money.
Perhaps the most common type of fixture is called the Cobra Head.
These lights, shaped like the head of the namesake reptile, allow
up to twenty percent or more of their light to escape sideways or
upwards. Their glare can also be painful to look at. Better lights
are the "shoebox" fixtures which are slowly becoming more popular.
These normally dark brown, box-like lights direct almost all of the
lumination downward but still provide a coverage pattern that allows
them to be used along city streets.
* The right type of lamp: The most efficient type of outdoor
light are called Low Pressure Sodium lamps, LPS for short. LPS can be
identified from their much more common, but not as efficient, cousins,
High Pressure Sodium lamps (HPS) by their deep yellow or dark orange
color. By contrast, HPS tends to look pink or light orange to most
people. However, LPS lamps, unlike HPS, emit only yellow light -
meaning that they are monochromatic - making it harder to see
different colors when you stand under them. Thus, it makes sense
to use LPS in situations - like all-night security lighting along a
campus or city walkway - where it is not necessary to be able to see
different colors.
* Effective use of lighting: All too often, homespun or even
municipal lighting is poorly designed and used in a shoddy fashion
without much thought given as to its desired effect. The results of
this are seen along glary, even dangerous roads and highways on rainy
nights. They may also be found along brightly - often too bright -
lit suburban roads were the glare from poorly shielded cobra head
fixtures cause the environment to be unattractive and even trashy.
Again, the main point is simple: Put the light were you need it!
The remedies are simple: Use glare-free full cutoff fixtures,
pick the best and most efficient light source for the job, and hire a
quality light designer or consultant who is knowledgeable about light
pollution and cares about good lighting - not a fast buck and $29.95
light fixtures.
While astronomers - both professional and amateur - are interested
in seeing more people and cities use low pressure sodium lighting,
because they can filter out the yellow light without affecting the
data they collect, Crawford and IDA suggests that a good solution is
to push for full cutoff fixtures and better education.
Nonetheless, LPS should be attractive to homeowner and cities
alike because of its affordability. A large city - one with 30,000 or
more street lights - will save over three million dollars each year
after changing from HPS to LPS. In addition to saving money, an
aggressive updating of street lighting will result in more savings as
old mercury vapor lights are exchanged and unshielded lights are
replaced by full cutoff fixtures.
A typical town street in the United States is lit with a string
of 200-watt High Pressure Sodium lamps. The HPS lamps, which each
produce an average of 19,800 lumens - a measure of the amount of light
- can be replaced with 135-watt LPS lamps that produce an average of
22,500 lumens. For each new LPS lamp installed, an average of 271
kilowatt-hours of electricity are saved and more light is aimed at the
ground. In a similar fashion, a homeowner can switch their 150-watt
incandescent porch light to an 18-watt LPS light and save close to
forty dollars per year, meaning that the 100 dollars or so cost of
changing the light is paid back in just two years.
Perhaps the biggest drawback to LPS is that it is hard to find.
Unless you live in an area where it is already in use - many U.S. West
Coast and Arizona cities and towns - it can be hard to find in local
lighting stores. Probably the best idea is to mail order lamps from
lighting stores in Tucson, Arizona, where LPS is required by law.
Even if LPS is rejected because of its monochromatic light, full
cutoff fixtures represent a major improvement. Full cutoff fixtures
are readily available across the U.S.. Even some hardware stores are
starting to carry full cutoff security lights. If you have a choice,
pick the right one! If you have an old-fashion 175-watt mercury vapor
lamp in your backyard - and it is old fashioned, as many of these
lights were designed in the 1930s - replace it with a full cutoff HPS
fixture. However, even with the choices on the market today, it is
still a matter of educating the people who light your streets,
shopping malls, office complexes, and the house next door.
And education may well be the most important key to bringing back
the night sky. The primary reason to light the night is for security.
We feel safer if we know that the area around our house or the streets
that we walk on are lit. Even though there is little, if any, direct
evidence to link a decrease in crime with an increase in lighting,
there is no doubt that increased lighting makes us feel more secure.
No one is asking that the lights be turned off, only that the light
be used properly. Good lighting only makes sense.
Aside from the efforts of groups like IDA, one of the best ways to
educate people is for you to help out. From talking to that neighbor
with a bad light, to passing a copy of this article to persons involved
in the lighting of your streets, to giving a short presentation to your
local officials, it is one of the best ways to educate. Our future is
literally at stake.

Light Pollution Education: Getting Started
If you are interested in improving the lighting in your area,
perhaps the first thing to do is to join the International Dark-Sky
Association (IDA). They have a large collection of "information
sheets" that are packed with lots of detail, ideas, and data. The
IDA address is:
International Dark-Sky Association
Dave Crawford, Executive Director
3545 N. Stewart
Tucson, Arizona 85716
U.S.A.
Telephone: 602-325-9346
Fax: 602-325-9360
Internet Address: crawford@noao.edu or dcrawford@noao.edu
This is important, for you will make a better spokesperson,
information source, or speaker if you know more about the topic -
light pollution - than anyone else there. Part of this process is
learning your own area. Look around at night. Identify locations of
good and bad lighting. Learn who is responsible and let them know -
good or bad - that you have noticed. Learn who is responsible for
designing the street lighting in your area. If you are the bashful
type, send them copies of this article or IDA handouts.
If you cannot see the stars at night, call up your local newspaper
and talk to a reporter about it. Send them copies of IDA information
sheets. Newspapers love to print human interest stories that can
also affect public policy. If you are the outgoing type and enjoy a
debate, contact a local talk-radio show host and convince them that
light pollution needs to be discussed.
"You have to learn who the people are in the local media. You
have to learn the names of the people in the city who will be making
decisions to allow such things to happen. And you have to get your
input in. After all, you are citizens and you have as much a right
as not to have that as the people who are doing the lighting," says
Crawford.
Arrange for talks at local groups, from the Boy Scouts to the
Lions Club. Network and talk to people. Chances are that you know
someone who is helping to set some sort of lighting policy somewhere.
Do not be afraid to approach schools. Talking to school children will
help insure that future generations will be sensitive to the issue of
light pollution. At the least they will have heard of the issue.
Sidebar 2 -
Doing Good Lighting
It might surprise many people as to how they can affect the
growth of light pollution. From the lighting of your own home to the
lighting of your work location to having a say about new street lights
in your community, many everyday folks come into contact with the
lighting of the night sky. More often than not, you can make a
difference.
One of the first things is to check out your own house. Replacing
those incandescent porch lights with low pressure sodium can have an
impact in your own community.
If you are involved in a lighting project at home or work, where
professional lighting designers/electricians are involved, make sure
they are members of the Illuminating Engineering Society of North
America (IES). While IES supports many of IDA's positions, be sure to
quiz the designers on light pollution. In the best of worlds, do not
hire them if they are not educated in this area. In a last resort,
educate them yourself. Insist on good lighting. It might be tempting
to buy those cheap fixtures now, but you will save money in the long
run if you purchase good fixtures with the best source of light for
the job.
Encourage public officials to make wise choices in regards to
night time lighting. Use LPS in full cutoff fixtures for street
lighting. At least drum in the idea of full cutoff fixtures. Also
encourage regulations controlling new lighting and requiring that
billboards be lit from the top and that billboards and building
lighting be turned off after midnight (12:00 a.m.).

Types of lamps and recommendations for their use:
Low Pressure Sodium (LPS) - This is the most efficient type of
light. However, because it is monochromatic, use where it is not
necessary to see colors. Roadways, walkways, and some parking areas.
Large outdoor areas needing security lighting.
High Pressure Sodium (HPS) - Sports parks and Tennis courts.
Security areas where color is needed. Some parking lots.
Metal Halide (MH) - Display lighting where color rendering is
critical. Some sports lighting.
Mercury Vapor (M-V, or HG) - Not an energy efficient source: Not
recommended. If color is needed, use MH or HPS instead.
Incandescent, including quartz - Not energy efficient, but okay
for low wattage applications. Good for infrared motion detector
security lights that need to turn on quickly.
Timers - These are good for many applications, like billboards,
decorative lighting of buildings, and outdoor scenes and some porch
lighting.
A source for LPS fixtures: Telephone The Ecology Store at (602)
327-3235 and ask for a copy of their catalogue or talk to one of their
consultants.

RECENT SOVIET LUNAR AND PLANETARY PROGRAM REVELATIONS
by Andrew J. LePage
As has happened so many times in the past couple of years, as
soon as I write an article on the former Soviet space program, new
and exciting information comes to light. In recent months, new
information on the early days of the Soviet lunar and planetary
exploration program has become available. One of the reasons I
have not published the next part of my recent "The Great Moon Race"
series in the EJASA is that I have been waiting for the dust to
settle somewhat from the most recent flurry of revelations to come
out of Russia and other parts of the former Soviet Union.
While the next installment in this series is still several
months away, I have had enough time to digest the new information to
summarize the Soviet attempts to explore the Moon, Venus, and Mars
during the late 1950s and early 1960s.
Early LUNA Missions
Since writing the article, "The Great Moon Race: In the
Beginning...", much new information on the early LUNA missions has
become available. No information has come to light on the possible
unsuccessful launches of May 1 and June 25, 1958, identified by
Western intelligence sources. However, there is new information
regarding the attempt made on September 23, 1958. This first
acknowledged launch took place on the afternoon of that day, but
failed when the VOSTOK launch vehicle broke up after ninety-two
seconds of flight.
The second presently acknowledged LUNA launch attempt occurred on
the morning of October 12, 1958, just hours after the launch of the
American lunar probe PIONEER 1. The Soviet Chief Designer, Sergei
Korolov, determined that a probe launched at that time would just beat
the American craft to the Moon. As it turned out, the VOSTOK booster
for this mission broke up just one minute and forty seconds into the
flight. An investigation of these two failures concluded that the
addition of the Block E escape stage to the basic R-7 rocket shifted
the launch vehicle's center of gravity in such a way that violent
resonant vibrations would occur after 1.5 minutes of flight, literally
shaking the ascending rocket to pieces.
No mention is made of a possible November 15, 1958 LUNA launch.
The next admitted attempt took place on December 4, just two days
before the launch of PIONEER 2. This LUNA failed due to a malfunction
in the core's RD-108 engine at four minutes and five seconds into the
flight.
The next attempt took place on January 2, 1959, with the launch of
LUNA 1. There is as yet no mention of an alleged follow on attempt on
January 9. The next launch attempt took place at some unspecified
date that summer (possibly June 16). This probe failed because of a
malfunction in the second stage's navigation system. The next attempt
was LUNA 2, launched on September 12.
After LUNA 2 successfully impacted the Moon, the Soviets turned
their attention to LUNA 3-style missions. This program succeeded on
the first try with the launch of LUNA 3 on October 4, 1959. Starting
the day after LUNA's October 7 picture-taking session, attempts to
transmit the images began. The first four transmissions were
unsuccessful because of the large amounts of noise caused by LUNA 3's
great distance from Earth. The first two images were finally returned
on the fifth attempt when the probe was closer and after special
measures were taken to minimize radio noise in the vicinity of the
tracking station in the Crimea. In all, seventeen images of "rather
satisfactory quality" were returned before LUNA 3 ceased to function.
After this mission, at least two additional LUNA 3-type probes
were constructed. They were designed to take higher resolution images
at closer range than LUNA 3 and were fitted with more powerful
transmitters to help improve the quality of the returned photographs.
The first attempt was made on April 15, 1960. This mission was cut
short when the Block E escape stage shut down too early, leaving the
probe in a short-lived, highly elliptical Earth orbit. This was a
fate similar to the early United States PIONEER probes.
The last attempt was the most spectacular failure of all. This
probe was rolled out onto the launch pad shortly after the failure of
the April 15 LUNA probe. On the afternoon of April 16, the craft was
launched and immediately ran into problems. The RD-107 engine of one
of the four strap-on boosters failed to ignite. After struggling
upwards 150 to 200 meters (500 to 650 feet), the VOSTOK launch vehicle
finally started to tumble out of control with all four strap-on
boosters breaking free of the core. Two of the boosters crashed and
exploded near the launch pad. Another passed a mere 30 to 40 meters
(100 to 130 feet) over the heads of some spectators located 1.5
kilometers (4,900 feet) from the pad. The rocket detonated on impact,
shattering the windows of the MIK (Assembly and Test Building) for the
VOSTOK. The core with the Block E escape stage and payload crashed
into a small salt lake some 800 meters (0.5 mile) from the pad. This
was the last Soviet LUNA mission until their landing program began.
Early VENERA and MARS Missions
The design work for the first Soviet interplanetary probes began
just as the first unmanned flights to the Moon started in middle 1958.
In August of 1959, the Applied Mathematics Division of the Mathe-
matical Institute of the Academy of Sciences of the U.S.S.R. released
a report detailing the requirements to reach Venus and Mars. It was
concluded that, using the 8K78 launch vehicle (now known as the
MOLNIYA) then under development, a 500-kilogram (1100-pound) payload
could be sent to Mars during the September of 1960 launch window
and an 800-kilogram (1760-pound) payload could be sent to Venus in
January of 1961.
It has been recently revealed that only one launch attempt to
Mars was made during the 1960 launch window. On October 14, 1960, a
probe similar to VENERA 1 was launched with the intent of impacting
on the Martian surface during the third week of May, 1961. Without a
mid-course correction capability, however, the chances of an impact
were slim. Only simple particle and fields instrumentation were
carried and no camera was included in this payload. Unfortunately,
this attempt reached a peak altitude of only 120 kilometers (74 miles)
due to a failure of the turbopumps in the RD-461 engine in the new
Block I stage.
While more than one probe was probably prepared for launch,
according to some sources this was the only launch attempt actually
made during that time. Another launch failure on October 10 that
was previously identified by Western intelligence as a Mars probe
apparently had nothing to do with the MARS program, just as an October
24 launch failure and deadly explosion of an R-16 ICBM development
flight was thought to be a Mars probe mission until being revealed
as otherwise in 1989.
Less than four months after their first attempt to launch a
spacecraft to Mars, the Soviets were ready for the Venus launch window.
The Type 1VA probes' mission was to, hopefully, impact on Venus.
As with the first Mars probe, these probes carried no mid-course
correction motor to negate any launch errors and fine-tune their aim,
so an impact was unlikely. Still, just in case one of the probes
chanced to be placed on a collision course with Venus, a small sphere
designed to float in any Venusian ocean that might exist was carried
containing a commemorative medal. This small sphere was placed behind
a "thermal cover" to protect it during the descent through Venus'
thick atmosphere.
These Venus-bound craft were hurriedly constructed. Due to the
tight schedule, many factory tests were not performed to save time.
The first probe was launched on February 4, 1961. Due to a timer
malfunction, the escape stage never ignited and stranded the Venus-
probe-to-be in a low Earth orbit. This new satellite was called
Tyazhyolyi Sputnik, or simply "Heavy Satellite". A second probe was
successfully launched on February 12 and eventually named VENERA 1.
Contact with VENERA 1 is now known to have been lost enroute to Venus
"on the second million kilometers of its trajectory".
The Next Round
In 1961, S. P. Korolov, the Soviet Chief Spacecraft Designer,
decided to use a single spacecraft design to explore Venus and Mars,
since the next launch windows for those planets (August/September and
October/November of 1962, respectively) were so close to each other.
This design was simply called Object MV. It was to serve as *the*
spacecraft design for all Venus missions for the next eleven years
and all Mars missions into the middle 1960s.
There were four variants of this design: The MV-1 had a launch
mass of 948 kilograms (2,090 pounds) and was designed to land a probe
on the surface of Venus. The 935-kilogram (2,060-pound) MV-2 was
designed to flyby Venus. MV-3 and MV-4 were designed to go to Mars.
The 1,042 kilogram (2,294 pound) MV-3 would deliver a lander to Mars
while the MV-4, weighing 1,037 kilograms (2,283 pounds), would conduct
a photographic flyby. As with the American SURVEYOR lunar lander,
these spacecraft proved to be too heavy for the launch vehicles then
available. A great deal of weight was shaved off the original
designs, especially the Mars probes.
Possibly as many as four of these new spacecraft were readied for
the Venus window, but only three were actually launched. The first
two, launched on August 25 and September 1, 1962, were Type 2MV-1 for
landing on Venus, but they were stranded in Earth parking orbits due
to failures in their escape stages. The third launch, on September
12, was for a Type 2MV-2 photographic flyby probe similar to MARS 1,
but it too failed.
Before the sting from these failures could wear off, the Mars
launch window opened. The first probe was launched on October 24,
1962, and was left stranded in its parking orbit. The second probe
was successfully launched on November 1 and became MARS 1. With a
launch weight of 893.5 kilograms (1,967 pounds), this MV-4 type probe
was about 144 kilograms (316 pounds) lighter than in its original
design. The third probe, launched on November 4, failed to leave
Earth orbit. No concrete information is available (yet!) on the
mission of the two failed probes but it is quite likely one or both
were of the MV-3 type designed to land on Mars.
The Early ZOND Flights
After this string of launch failures and with the early demise of
MARS 1 before reaching its intended target, two new MV designs were
developed. These probes, called ZOND, were stripped-down engineering
test versions of the previous MV design. Two types of spacecraft were
designed: ZOND A, with a launch mass of 800 kilograms (1,760 pounds)
was equipped for a flyby of Venus. ZOND B weighed in at 996 kilograms
(2,190 pounds) and would be targeted for a Mars flyby.
The first of the ZOND missions, using a Type 3MV-1A probe, was to
be launched towards the Moon to provide a test of vital flyby systems
close to home. Launched on November 11, 1963, this first engineering
test became the victim of an all too common experience of previous
probes. The escape stage failed to operate and the probe, now called
KOSMOS 21, was stranded in Earth orbit.
The next batch of four Type 3MV-1A ZOND probes were meant for
exploring Venus. The probes launched on February 19 and March 1,
1964, never even made it to Earth orbit. A third craft, launched on
March 27, got stranded in its parking orbit and was named KOSMOS 27.
The last, ZOND 1, weighing 825 kilograms (1,827 pounds), finally made
it into a Venus-bound trajectory only to fail enroute. These are the
only known flights of either original ZOND design.
The next ZOND missions apparently made use of improved versions
of the original MV design. The details of the late 1966 Mars window
payloads are still hazy. While only ZOND 2 was actually launched
towards Mars on November 30, 1964, at least one MV-4 flyby spacecraft
carrying a photo-television and spectrometer package was scheduled to
be launched to "complement" the payload of ZOND 2. While this is not
quite yet proof, it strengthens the belief I have supported that ZOND
2 was a MV-3 type probe meant to land a package on the surface of
Mars. The MV-4 type spacecraft that missed this launch window was
eventually launched on July 18, 1965, as ZOND 3. This vehicle
conducted a photographic flyby test of the Moon.
During the next Venus launch window, four probes, two of each
type, were prepared for launch. The first launched was a 3MV-2
spacecraft on November 12, 1965, named VENERA 2. The second, VENERA
3, was launched on November 16 and was a Type 3MV-1 lander. A third
probe, also a Type 3MV-1 lander, was launched on November 23, but due
to an escape stage failure, it was stranded in an Earth parking orbit
and became KOSMOS 96. The fourth and last probe, a 3MV-2 flyby probe
like VENERA 2, was launched on November 26 but failed to achieve Earth
orbit.
Later Mars and Venus Missions
After five unsuccessful Mars and thirteen unsuccessful Venus
missions, along with the death of Korolov in January of 1966, the
Soviets changed their direction. All work on the planetary probes
was transferred from the Korolov Design Bureau (then deeply involved
in the Soviets' manned lunar landing mission development) to the
Babakin Design Bureau. No more photographic missions to Venus would
be attempted. Instead, all work in this area was directed towards
preparing two highly modified MV-1 payloads, known as V-67, to land
on Venus.
Not much is still known about the direction of the MARS program
at this time, but all further flights of MV-3 and MV-4 payloads were
suspended. The American Mars probe, MARINER 4, probably dealt the
Soviets a double blow: First, data returned from MARINER 4 in July of
1965 indicated that the Martian atmosphere was at least a factor of
ten thinner than previously believed, making the MV-3 lander design
useless. Second, the Soviets at the time had the mindset of "do it
first or, if someone does it before you, do not do it at all". The
fact that MARINER 4 succeeded in its photographic mission made flights
of the MV-4 design politically unnecessary.
Instead it appears that the Soviets began design work on a new and
heavier spacecraft to be launched towards Mars using the new 8K82K or
PROTON rocket vehicle. It has recently been revealed that the first
pair of these spacecraft were launched towards Mars on March 27 and
April 14, 1969. These probes were similar to MARS 2 and 3, launched
in 1971, but did not carry landers like the failed KOSMOS 419, also
launched in 1971. The 1969 probes were meant to be orbiters and would
have beat the Americans to Martian orbit by two years. The Soviet
craft would have also made the mission of MARINER 6 and 7 - scheduled
for a late July and early August, 1969 flyby of Mars - look second-
rate.
Unfortunately, while the MOLNIYA had matured to the point where
launch failures were relatively uncommon, the PROTON was still plagued
with failures. Both new Mars probes failed to reach their Earth
parking orbits due to the relatively new Soviet booster.
