on April 19 1971 the first space station in history solute 1 had just been placed
in low earth orbit by the Soviet Union on June 6 1971 the soyuz 11 would undertake a journey
to the orbiting space station with cosmonauts giorgi dobrevolsky vladisav volkov and Victor
patsayev inside three cosmarats from the soyuz 11 spacecraft successfully boarded the salute 1 space
station on June 7 1971. they were there for three weeks of research projects including the growth of
Chinese cabbage and bulb onions the creation of star spectrograms and the taking of photographs
of the snow and ice on the river Volga from orbit but what happened to these three cosmonauts let's
find out while Elon Musk update us all hello everyone welcome back to Elon Musk Evolution
where we bring you the most recent news about Elon Musk and his multi-billion dollar companies space
news and the latest science and technology but before we begin make sure you subscribe to our

musk It's a Small Wonder that only three people have lost in space out of 562 who have ventured
beyond the safety of Earth five times as many people have perished as a result of crashes or
explosions while escaping or re-entering our planet's atmosphere they were now well-known
Heroes and frequently appeared on Soviet evening television the soyuz 11 finally separated from the
salute one on June 29 1971. after the cosmonauts primary mission was finished three hours later the
astronauts fired their ship's engine to return to earth vladislav volkov made a humorous request of
flight control asking them to make sure their customary welcome home gift of cognac would be
there when they landed to separate the orbital bell-shaped capsule and instrument modules from
the soyuz 11 at 29 minutes before touchdown and at a height of 160 kilometers explosive
charges were fired as directed The cosmonauts only protection from the Raging furnace of re-entry was
now the Space Capsule then however something unexpected transpired the pressure inside
the crew capsule rapidly dropped as soon as the other modules were jettisoned and all of the air
inside started escaping into the vacuum of space unfortunately Mission Control remained oblivious
of the situation there was a startling quiet when the cosmonauts tried to be reached on the VHF
radio which caused the room to become uneasy the capsule was detected on radar as it entered Soviet
airspace 22 minutes before touchdown Mission controllers knew that while the capsule was still
re-entering the atmosphere it would be wrapped in a cloak of plasma and consequently contact would
be difficult during this period musk explained as the minutes passed by expectations for a happy
ending were reignited when the space capsules drogue parachute autonomously released followed
by the larger main parachute cover followed but there continued to be no signal from the crew
and five minutes before touchdown helicopter Crews noticed the completely intact soyuz 11 leisurely
swinging back and forth under the Flawless looking parachute when the chopper Commander radioed that
the capsule had landed safely Mission Control was delighted after spending three exhausting weeks in
Space the recovery team was staying close by and was just minutes away from opening the hatch to
give the cosmonauts their Cognac and other Home Comforts two minutes after touchdown the two-man
search and rescue crew arrived at the soyuz 11 and then pounded on the hull of the ship to alert them
to their presence however there was Silence from inside after opening the hatch a look of deeply
Disturbed uncertainty visible in the face of one of the rescue crews the recovery crew discovered
the three cosmonauts all slumped and motionless inside the spacecraft blood was pouring out of
their ears and noses and their faces were painted in dark spots that appeared to be bruises although
Deborah volsky one of the cosmonauts was still warm efforts to revive him ended in Failure the
very first engagement between the recovery crew and Mission Control resulted in the use
of three numbers one one one according to musk this was a code that defined the health of the
cosmonauts the numbers 5 indicated excellent condition four indicated good condition three
indicated there were injuries two indicated there were significant injuries and one indicated there
were fatal injuries and now let's take a closer look at what went wrong investigators concluded
Deborah volsky and volkov had unbuckled themselves from their seats to look for the leak that was
letting air escape from the capsule based on the positions of the three cosmonauts bodies when they
were discovered their heart rates increased while they searched according to their hot monitors
however time was not on their side as within only 50 seconds patsayev's pulse fell as his
body became starving for oxygen and then within 110 seconds all three crew members had died in
the process officials had discovered that a defective valve was the main reason of the
unfortunate incident the entire nation mourned their passing and their funeral was epic on a
grand scale all human space flights were put on hold by the Soviet Union while Engineers
overhauled the soyuz spacecraft now during takeoffs and landings all cosmonauts are required
to Don spacesuits musk pointed out that other nations have also experienced space disasters
that claim the lives of valiant astronauts with the brilliant engineering of the reusable space
shuttle the U.S was setting the standard for space travel worldwide however issues can arise with
even the most sophisticated spacecraft after the first space shuttle launch on April 12 1981 and
after Americans had grown accustomed to seeing the space shuttle launch the US appeared to be
growing bored with space travel by January 1986. since its first flight the program had run without
any issues however everything would soon shift on the dawn of January 28 1986 the crews of mission
sts-51l boarded the spacecraft Challenger it was a beautiful but cold Tuesday Morning
everywhere in the USA Americans were a little more enthusiastic with this launch because its crew of
Seven astronauts included payload expert Krista McAuliffe who was a housewife school teacher
and mother of two children she was an active participant in the teacher in space initiative and
living proof that everyone in America could now travel into space not just the best fighter pilots
Ellison onizuka Judith Resnick and Ronald McNair were among the mission Specialists operating the
Challenger shuttle under dick scoby's command Gregory Jarvis was Krista McAuliffe's fellow
payload expert Krista McAuliffe was aboard the space shuttle Challenger when it took off from
Cape Canaveral Florida making history as the first regular American to travel into space
however after just 73 seconds and with hundreds of Spectators on the ground watching which include
Krista's family and a small group of students and millions of Spectators waiting to watch the launch
on television the space shuttle disintegrated into a fireball in smoke so what really happened
we noted that the morning was extremely cold in reality two hours before the launch there
was ice on the tower an overnight measurement made by the ice crew revealed readings on the
left solid rocket booster at -4 degrees Celsius while the right SRB was minus 13 degrees Celsius
the temperatures of the solid rocket boosters were not included in the launch commit criteria hence
these measurements were only taken for engineering purposes and were not published the solid rocket
boosters for the shuttle are composed of four segments that are bolted together at three o-ring
joints before we continue these O-rings are in place to hold internal pressure of the SRB and
any failure of these O-rings would generate a burn through triggering a catastrophic engine
failure to the right solid rocket booster this is exactly what transpired right before liftoff
there was a cloud of black smoke from the SRB indicating that the O-ring had already
failed Flames began to emerge from the broken o-ring by the time the shuttle was in the air
and the sideways Flames sliced through the SRB like a cutting torch the Seven astronauts the
1.2 billion dollar spaceship and its satellite payload perished in Space instantaneously the
cold played a major role in the accident Engineers were aware of the risks to the O-rings at such low
temperatures because the launch was conducted in weather that was -3 degrees Celsius nevertheless
despite numerous engineer cautions the shuttle was given the all-clear to Launch following
this terrible tragedy NASA suspended the space shuttle program for two years while its Engineers
completely redesigned the shuttle's various parts however it wouldn't be the final space shuttle
mishap in April 1981 the space shuttle Columbia was the first shuttle to be launched into space
27 more times after its Maiden flight the shuttle launched again and it was on its 28th flight on
January 16 2003 the seven-person sts-107 crew included flight engineer kalpana Chola who had
previously flown on the mission mission Commander Rick D husband pilot William C McCool payload
Commander Michael P Anderson Israeli astronaut Elon Ramon who served as a payload specialist
and U.S space shuttle mission sts-87 David M Brown and Laurel Blair Sultan Clark our Navy
captains who were flying as Mission Specialists there were no obvious issues during the launch
during their 16-day expedition the astronauts successfully completed 80 science and research
projects while work talking in two alternating shifts 24 hours a day the crew needed to head
back to Earth and the space shuttle Columbia was due to re-enter the atmosphere and touch down
on February 1 2003 the entry flight control team at Mission Control began their shift at 2 30 a.m
Eastern Standard Time the crew organized their belongings inside the Orbiter and got ready for
re-entry husband with McCool started going through the entry checklist and at 1 10 pm the Columbia
crew was authorized to perform their deorbit burn where it lasted 2 minutes and 38 seconds at 1 44
PM Columbia re-entered the atmosphere at a height of 120 kilometers four and a half minutes later a
sensor began measuring a greater than normal amount of force on the left wing however the
data from the sensor was sent to an internal recorder and was not visible to the crew or
ground controllers The increased drag resulted in the Orbiter starting to yaw to the left the
problem was fixed by the orbiter's flight control system and the crew was never made aware of the
drag or what was going on musk stated sensors then showed issues with the hydraulic systems
on the left wing and the left side Landing Gear's tire pressure dropped the last communication from
Columbia was received by flight controllers as it was traveling at a speed of 20 120 kilometers per
hour and was 60 kilometers above the Earth the Orbiter broke up and disintegrated as
many witnesses watched in horror on video what transpired to the crew of the Columbia
following Colombia's launch the inter-center photo working group of NASA was performing
a routine review of the launch videos It wasn't until the second day that they discovered a piece
of foam had broken off from the massive external tank and damaged the left wing as the shuttle was
Rising into orbit multiple requests for images were made to the U.S Department of Defense after
the debris management team was unable to assess the left Wing's damage our request was sent to
the U.S strategic command which started looking for equipment that could take pictures of the
Orbiter however after learning who made the request NASA Mission management team chair
Linda Hamm rejected the request for an image she didn't ask the debris assessment team
instead she asked a flight director about the Imaging requirement it would have interfered
with ongoing science operations to move the Orbiter into a position to be photographed
and ham regarded the department of defense's Imaging capabilities as insufficient to assess
damage to Colombia's left wing now here is when things get more intriguing in Communications with
the Columbia crew mission management downplayed the risk of a debris strike and flight director
Steve Stitch emailed husband and McCool to inform them of the strike and to reassure them that there
was no need to worry about damage because foam strikes had happened on earlier flights they
were obviously mistaken this was The Smoking Gun that established that Colombia's demise and the
loss of her crew were caused by the damage from the debris strike it was the final space shuttle
launch and this marked the end of the space shuttle program since then the Russian soyuz
program and now spacex's Rockets have been used to launch astronauts into space and that ends
