Voskhod 2: 50 years ago today
« on: 03/18/2015 07:04 AM »
On March 18th, 1965 the Soviet Union launched the world's second multi-manned spacecraft - Voskhod 2.   It carried Pavel Belyeyev and Alexei Leonov.   It was Leonov who grabbed the headlines when he became the first man to complete a spacewalk.

It was not until a year later - following the emergency return to Earth of Gemini 8 - that the Soviets announced that Voskhod 2 had landed far off course after the primary retro-rocket system had failed to fire and the cosmonauts had used the back-up system.   It took even longer to come out how close to death Leonov had been because his EVA suit bad ballooned more than predicted and the only way he could get back inside Voskhod was by lowering the suit pressure to a dangerous level to counter the ballooning.

Did the announcement of the mission to the West happened before, during or after the EVA? (liftoff was at 07:00 UTC and right now 50 years ago Leonov started airlock depress)

EVA at 50: Cosmonaut Alexei Leonov took first spacewalk 50 years ago
http://www.collectspace.com/news/news-031815a-spacewalk-50th-alexei-leonov.html

It lasted just 12 minutes, but history's first-ever spacewalk – 50 years ago today – took the first steps towards shaping the future of space exploration.

On March 18, 1965 at 4:35 a.m. EDT (0835 GMT), Soviet-era cosmonaut Alexei Leonov became the first person to leave the confines of his spacecraft while in orbit and float in the vacuum of space. Leonov, who with Pavel Belyayev was flying onboard the former-Soviet Union's Voskhod 2, accomplished the first extra-vehicular activity – EVA, or spacewalk – on what was only the 14th piloted spaceflight in history.

"What remain etched in my memory was the extraordinary silence, my heart beating, and difficulty I had breathing," Leonov recalled five decades later in an interview with the Fédération Aéronautique Internationale (FAI). The FAI was then, and remains today, the governing body that certifies world aviation and space records.

According to the New York Times' article on March 19, 1965:

The announcement of the successful launching came simultaneously and solemnly and triumphantly- over all Soviet radio stations at 11 in the morning [Moscow time], an hour after blastoff.

The EVA began 90 minutes into the mission at the end of the first orbit, so the mission was announced about a half hour before the spacewalk began.

RT's anniversary article about the flight:

Quote
Fifty years ago pioneer Soviet spacewalker Alexey Leonov made his famous jump into the silence of outer space, overcoming his own biggest personal challenge and marking a significant step in the history of space exploration.

The first spacewalk became an epic hero tale reported and hailed in every major newspaper in the world exactly five decades ego.

“Russian floats in space for ten minutes; Leaves orbiting craft with a lifeline,” was the headline story featured in the New York Times half a century ago. “US officials salute latest Russian feat,” papers reported on March 18, 1965.

And an upcoming Youtube/Google/RT Russian event (countdown timer running):

I was 12 years old when I saw the smudgy, first edition, newspaper photo of this first space walk. This was the first time in my life that I recall feeling what is now called the "uncanny valley" (http://en.wikipedia.org/wiki/Uncanny_valley) experience. The blobby image *looked* human-like, but the poor halftone reproduction from a poor photo of a poor video image gave this then-impressionable young boy a very weird feeling that I still find myself trying to reconnect with as I see these much cleaner stills from the original films. That was a heady era in history--so much was happening at a furious pace. There was no previous history for any of us to connect this event with, which added to the odd newness of the accomplishment. As we look back now with perhaps jaded emotions, it is worth recalling those feelings and impressions that seem to fall into skeptical disregard over time. Hats off! (erm, helmets off?) to Alexei and Pavel for this brave feat.

Dear Alexei Arkhipovich,

50 years ago, man stepped out from space vehicle and performed space walk for the first time in history.

We congratulate You on this significant date and take pride in the fact that You, our contemporary and compatriot, is that man.

"Success of this flight was every bit as important as success of the first-ever space flight for further development of cosmonautics. Belyaev and Leonov were able to cope with the task and significance of this exploit can scarcely be exaggerated,"  -  said S.P. Korolev, the General Designer, founder of national cosmonautics about that epoch-making event of world importance.

You really performed a deed: by risking your life you have achieved long-standing dream of mankind about conquest of outer space. Thanks to your efforts, not only world cosmonautics, but also human civilization rose to a higher level of its development.

We are lucky and have the honour to live with great people at present. Magnitude of your personality, great achievements in rocket-space industry, inestimable contribution to development of its scientific-technical potential allow to rank You deservedly as one of those great people.

Your career of the creator and space explorer is also your personal example of purposefulness, creative daring for us.

RSC Energia collective takes pride in their participation in this remarkable event. Today our corporation continues to keep its leading position in space exploration by implementing ambitious technical projects and having confidence in the future.

We feel certain that the results of our efforts to build up-to-date rocket-space technology will be worthy of your great exploit!

Thank you for your active attitude to life and the contribution that You continue to make to strengthening and promotion of Russian cosmonautics traditions of many years.

On this significant and memorable day, please accept our sincere congratulations, our gratitude and wishes of inexhaustible vital energy, good health, happiness to You and your relatives.

Management and collective of RSC Energia

The first egress of man into space is 50 years
March 18, 2015
Today 50 years have passed since the first egress of man into space. Soviet cosmonaut Alexei Leonov on March 18, 1965 left the board of Voskhod-2 being in orbit and stayed in space 12 minutes and 9 seconds. This egress proved the possibility of extravehicular activity of man in space and opened a new page in the history of world cosmonautics.

According to the statement of RSC Energia Department senior researcher Arkadiy Guzenberg engaged in life-support systems and environment conditions, who personally participated in the preparation of the historic spacewalk, the significance of this event can be compared, perhaps, with the flight of Yuri Gagarin only.

– This was the beginning of the next cycle of the space age. The risk was enormous. We worked in the 9-th department of OKB-1, which was led by Konstantin Feoktistov. We were responsible for the descent vehicle atmosphere: its composition as well as maintaining the required pressure in the cabin and docking to the airlock. NPP Zvezda specialists were responsible for the airlock itself and the extravehicular spacesuit. One had to solve the problem of leakage and separation of the airlock that was extremely difficult to test on the ground with regard to space conditions.

Everything was for the first time: the airlock was inflatable and the handholds which can be grasped were envisaged in its end part only. (Later on the Mir and ISS Stations special routes with handholds were laid outside the module bodies).

To go on a spacewalk - one had to possess extraordinary power and determination. Leonov is a man with tremendous endurance, who was able to find his way quickly in an emergency situation, namely released pressure in the spacesuit, could squeeze in the airlock before shadowing. 

The problem was solved on a background of serious difficulties: from some increase of oxygen content in the cabin after Leonov spacewalk to problems with making a landing which, as You know, had to perform manually in snow-covered taiga. Therefore, it is impossible to overestimate the importance of a successful flight of the crew consisting of Pavel Belyaev and Alexei Leonov for Science and Technology, - said Arkadiy Guzenberg.

"One can live and work in space - these words of Alexei Leonov at the State Commission marked the beginning of extensive research of functional capabilities of men being in weightlessness conditions, the creation of specialized space tools and technical devices, development of methods for restraint in weightlessness, modification of protective equipment. Today extravehicular activity became an integral component in practice of operating orbital stations. For half a centaury the Russian cosmonauts did about 150 extravehicular activities in space. Due to this fact a large scope of work was performed on the assembly and disassembly of the external equipment, provision of efficiency of the station units and assemblies, many scientific experiments were conducted. The record concerning the number of egresses and total duration of staying in space belongs to Russian cosmonaut Anatoly Soloviev.

Here is a link to an Associated Press story from 9-days after the Voskhod 2
flight mentioning a system failure causing the craft to spend an extra orbit
in space and land 500 to 600 miles off target. The two cosmonauts had mentioned
this in a press conference the day before.
