Good news from the Titanic

A stroll to the Syr Daria today shows that the river is completely unfrozen now. This is a real change from the landscape we had in January when we arrived in Baikonur.
The water level is rather high at the moment. This is due to the melted ice coming from the Uzbek mountains. In summer, according to local people, the shallow waters enable to reach by foot the islands in the middle of the river with water up to the hip only.

On the ground, ice crystals are slowly but irreversibly melting at the foot of the reed canes under the tepid sun of March,

and CryoSat-2, despite a launch on April the 8th will not be able to map the last few large ice sheets left along the Syr Daria banks.

We all are waiting for the accurate data Cryosat-2 will provide once in space, but we already strongly suspect a negative balance of ice on the planet which has already triggered alarming signals for some of our polar friends...

However, there is may be one place in Baikonur which is not going to complain about this seasonal warming or for which ice melting is not bad news at all. This place is called the Titanic. Why?
Certainly not because of any kind of icebergs (even if melting) this time...

In Baikonur, the Titanic is the name of the wreck (above) that has been pulled up onto the upper bank of the Syr Daria to become a restaurant and a "Bier garten" during the spring/summer period. It is still closed but should open as soon as the weather conditions will improve, offering to the "Baikonurtsi" a nice place for social events with a gorgeous view on the river and the steppe.
How this ship ended her life at this place? One can only speculate. Earlier, at the time the flow of the river was more stable and the Aral sea was still a sea, she was may be carrying passengers along the river from place to place. The development of the intense irrigation to support cotton and rice cultures has drained the river (and the Aral sea) making these trips impossible today.
A quick look on the web shows that most of the Aral sea has become a cemetery for ships of this kind.

A last remark about the city itself and the river: In fact when the was city developed at this place as from 1955, the engineers started the settlements and then the construction of the city on the right bank. The (natural) idea would have been to build a city over the 2 banks of the Syr Daria. This idea was abandoned due to the non predictable behavior of the river flow. It was decided very early, that the city would grow along the river but on the right bank only.

Growing trees in the desert

Growing trees in Baikonur has to be seen as a prowess, The semi desert landscape that surrounds the space city shows that a very limited number of trees species can naturally grow in the extreme conditions of this area.

Therefore, almost all species have been imported in the "new city" and ingenious solutions have been found to resolve problem such as:
  • no water in the immediate under ground as well as no much rain
  • high temperature in the summer period associated with drought
  • a limestone clay and sand type of soil which is rather poor in organic elements,
  • the salt of ancient sea that has contaminated lower geological layers,
  • freezing temperature which is a killer for bark and the blossoms or young leaves,
  • etc...
Trees do have a hard life in Baikonur:
Not only from the nature :-)

Only sustained and continuous efforts make the miracle possible: To grow trees in the desert and make the new city "green".
Since a couple of days, many environmental technicians and agents are at work in the Baikonur streets to prepare fort the big seasonal transition.

The first visible action is the pruning. It has started here in the Peace Park for a week already,

or next to the Arbat street where you can observe a more drastic cutting. Note the white colour at the bottom of the trunk. This "white painting substance" is used everywhere to fight against parasites/fungi and to prevent bark cracking during freezing periods (?)

Large quantities of fresh ground are transported to the city by trucks.

This is used to replenish the soil at the foot of the trees bringing essential nutritional elements.
Korolev Prospekt

Burning dead herbs of the past season is a also a widely used technique in Baikonur. This let to think that soils are rather acidic as ashes brings potassium and carbonates that will slightly increase soil pH .
Here, on the Gagarin Avenue, as well as everywhere else in the city, a dense piping system bring the necessary water to the plants in the warm season.

At the same place, dried Camel feces is also widely spread as a natural (and local) fertilizer.

Dead trees are replaced by new plantations properly supported.

At many places, one can also observe the digging of the unfrozen soil, the necessary preparation for new flowerbeds like here under in front of the Science and Cosmos Stela.

All these efforts will for sure pay in a couple a weeks when the season change will definitely make us forgetting the very cold winter. The city will suddenly look like an "oasis in the desert".

A description of the various acclimatized species of trees that can be found in Baikonur parks definitely deserves a dedicated message.

The Steppe (draft)

Kazakh Steppe around Baikonur, as we discover it on our commuting trips every day from hotel sputnik to the MIK in the cosmodrome always offers a wide range of extremely beautiful landscapes.

Light at Dusk and dawn makes the landscapes simply amazing.

Sun rise on the steppe when arriving at the MIK in the morning (ca 09:00 am)



The steppe during day light (observation point for Launch pad #109)


A young dog used to live in the steppe


...and likely his or her mother few meters away.


Sun set on the steppe when leaving the MIK (ca 18:00)



A. Tchekhov's novel "the Steppe" - or the story of a trip, describes the fascination of the Russian writer for that kind of desert land. In this novel, partly autobiographic, A. Tchekhov is the young Iegorushka on the horse pulled carriage traveling together with his uncle Kouzmitchov (a wool trader) and Father Khristofor an orthodox priest. Another interesting character is Deniska the carriage coachman.

The young Iegorushka leaves home for the first time for going to high school in a larger city. It is mid summer time. The kid is a bit afraid by this adventure but he is also amazed by this trip so that he will remember it all his life long.

The Steppe is one of the first Tchekhov's novel (published in 1888) after he revisited ca 1887 the country of his childhood around Taganrog on the North East side of the Black Sea where he was born. The Novel is a sequence of sections describing a trip through the steppe likely between Tangarog and Rostov (?). It is also a sequence of beautiful paintings depicting the variety of the steppe: Fauna, storm, overnight in the Jewish inn, churches and villages, nomads, wool traders, legends... A. Tchekhov himself, very proud of this work, would have said "it is my master piece".

He describes with lot of emotion the beauty of these changing landscapes. He also says that there are no better places than the steppe to observe the starry sky at night.
