SOYUZ ROCKET BLASTS PROGRESS CARGO SHIP ON WAY TO RESUPPLY ISS

A Russian Soyuz rocket has successfully lifted the 60th Progress transport cargo spacecraft into space from the Baikonur Cosmodrome in Kazakhstan, launching it on a mission to resupply the International Space Station.

The Progress M-27M is due to deliver more than 3 tons of food, fuel and supplies to the Expedition-44 crew. 

Although the three men on board the ISS – Gennady Padalka, Mikhail Korniyenko and Scott Kelly – have enough supplies to last them until autumn, the arrival of the cargo ship is crucial. 

Two previous missions to deliver supplies to ISS were unsuccessful, resulting in the loss of the ships and their cargo. 

At the end of June, an unmanned Falcon 9 rocket carrying more than two tons of supplies exploded shortly after lifting off from Cape Canaveral. 




In April, the Russian Progress vessel entered the ‘wrong’ orbit and ended up in an uncontrolled spin around the earth, making docking at the International Space Station (ISS) ‘impossible’. 

This time the cargo ship was taken into space by a different type of booster – the Soyuz U. 

It will take a longer route than usual and reach ISS on July 5. 

It is carrying 1,940 pounds of propellant, 106 pounds of oxygen, 926 pounds of water and 3,133 pounds of crew supplies and research equipment.

MOSCOW (AP) — A Russian booster rocket on Friday successfully launched an unmanned cargo ship to the International Space Station, whose crew is anxiously awaiting it after the successive failures of two previous supply missions.

A Soyuz-U rocket blasted off flawlessly from Russia-leased Baikonur launch pad in Kazakhstan, placing the Progress M-28M ship into a designated orbit, safely en route to the station. On Sunday, it's set to dock at the station currently manned by Russians Gennady Padalka and Mikhail Kornienko and NASA's Scott Kelly.

The ship is carrying 2.4 metric tons of fuel, oxygen, water, food and other supplies for the crew, the Russian space agency Roscosmos said.

The previous Progress launch in April ended in failure, and on Sunday a U.S. supply mission failed too when SpaceX's Falcon 9 rocket broke apart shortly after liftoff. The mishaps were preceded by last October's launch pad failure of Orbital Sciences' Antares rocket, also carrying station cargo for NASA.

Despite the failures, NASA said the station is well-stocked, with enough supplies for the crew to last at least until October.

However, the trouble-free launch Friday was essential for the station program, which has exclusively relied on Russian spacecraft for ferrying crews after the grounding of the U.S. shuttle fleet.

SpaceX still hopes to meet the target of launching astronauts from U.S. soil again aboard the Falcon-Dragon combination in December 2017, which would allow NASA to stop buying seats from Russia to get astronauts to the space lab.

The Soyuz rocket is used to propel both Soyuz manned spacecraft and Progress cargo ships to orbit, so the launch of the station's next crew of three has been pushed back from late May to late July as space officials have looked into the reason for the rocket failure in April.

Russian space officials eventually have traced the failure to a leak from fuel and oxidizer tanks in the booster's third stage, which they said was caused by a yet unspecified flaw in the interface between the cargo ship and the latest Soyuz modification, called Soyuz 2.

The Soyuz-U rocket used Friday is an older sub-type of the rocket, which has been the workhorse of Soviet and Russian space programs for nearly half-a-century. Last month, the Interfax news agency reported that the Russian space agency will only be using that Soyuz modification until experts fully understand the reason behind April's failure and fix the flaw.

The station program has been one of a few sectors where ties haven't been hurt by a bruising Russia-West showdown over the crisis in Ukraine.

Russian rocket takes off to resupply ISS after 2 American and 1 Russian missions failed

Story highlights

(CNN)Resupply missions to the International Space Station rarely fail -- let alone twice in row, like the last two did. 

That may make the arrival of the Russian cargo spacecraft that launched Friday all the more welcome -- even if the ISS does keep a large backlog of supplies on board.

The crewless ProgressM-28M lifted from the Baikonur Cosmodrome in Kazakhstan just before 8:00 a.m. local time (12:00 a.m. ET / 5:00 a.m. GMT) and cut a clean path through a clear blue sky en route to a low-Earth orbit.

Minutes later, the Soyuz-U cargo vehicle successfully separated from the rest of the rocket, according to the Russian Federal Space Agency, also called Roscosmos. 

And it was on course to deliver 5,249 pounds (2,381 kilograms) of supplies to the ISS on Sunday. They include food, water, oxygen, fuel and scientific apparatuses. 

Mission fails

Missions like this are fairly routine, but three spacecraft bound for the ISS with tons of supplies have been lost since last October -- including the two most recent. 

This past Sunday, one American rocket blew to pieces shortly after liftoff.
The SpaceX Falcon9 rocket was boosting a Dragon supply capsule stocked with a spacesuit, water filtration equipment, food, water, and experiments submitted by students. It also carried a docking adapter which was to allow people to arrive aboard America's first crewed spacecraft since the space shuttle.
All was lost.

On April 28, the last Russian rocket that launched on a resupply mission went out of control and ended up in an orbit incompatible with that of the ISS. It eventually burned up in Earth's atmosphere along with clothing, spacewalk hardware, propellant, oxygen, water, spare parts, supplies and experiments.

And in October 2014, a rocket on a resupply mission had to be detonated, when its launch went awry right after liftoff. The Antares, made by the Orbital Space Sciences Corporation, was carrying provisions, experiments and equipment.

"We've always assumed we would lose a vehicle every so often," said Michael Suffredini, manager of the International Space Station Program for NASA. "Having three this close together is not what we'd hoped for."

But the ISS was prepared. Even after the SpaceX Falcon9 exploded on Sunday, it had enough supplies to last the crew until October, at least. 

Life on the ISS

The station orbits about 248 miles (400 kilometers) above Earth. It circles the planet every 90 minutes. 

NASA says more than 200 people from 15 countries have visited it since November 2000.

The ISS measures 357 feet end-to-end and has more space than a six-bedroom house.

What do the astronauts do up there? Mostly, they conduct experiments. But they also exercise to offset the effects of near-zero gravity.

If you want to see it with your own eyes, NASA can tell you when it will be flying right over your hometown. It looks like a high-flying airplane tracing a beeline across the sky.
