SpaceX third try a success
Following two delays because of technical issues during countdown SpaceX successfully launched the SES-8 spacecraft on Tuesday.  This was a critical mission for SpaceX as it was there first to GTO and also the first to require a re-light of the second stage engine to ensure the spacecraft arrived at the proper orbit.

Unlike the previous two attempts the countdown went smoothly and the spacecraft lifted off on time for approximate 9 minute climb to the initial orbit.  Once in orbit the second stage and spacecraft cruised for another 18 minutes before the second stage fired its engine for 71 seconds to place it in the correct position to release the spacecraft into it’s designated orbit.

While the final stages of the flight were not broadcast live Elon Musk sent out several tweets advising of the progress of the mission and confirmation that the spacecraft had been delivered as expected.

Next up SpaceX will be flying another mission from the Cape, this time for Thaicom this was original scheduled to fly at the end of December, however this may change because of the delays in the SES-8 flight.

China’s Chang’e-3 arrives in Lunar Orbit
The Chang’e-3 spacecraft has arrived in it’s initial Lunar Orbit less then five days after it launched aboard a Long March rocket.  The spacecraft will now prepare for a historic rocket assisted landing on the moon later this month, assuming the landing is successful China will be the third nation to land a vehicle on the moon, Japan has impacted on the moon but not landed a craft that explored further.

Orion Heat Shield Ships
As the test flight for the Orion spacecraft draws closer another major element on the craft was shipped to Kennedy Space Center to be integrated.  The Heat Shield which will protect the craft from the intense heat of reentry was shipped from Manchester, NH via a Super Guppy aircraft.

Most distantly orbiting exoplanet discovered
ooexoplanetThis week astronomers announced the discovered of an exoplanet that according to current understand of planetary formation shouldn’t even be there.  The planet HD 106906 b measures in at 11 times the mass of Jupiter and is estimated to orbit at 650 times the Earth-Sun distance.

We are back after a rather long delay due to upgrading to Windows 8.1 and losing everything that was installed on the machine :(…

Cygnus completes COTS demo mission
The Orbital Sciences Cygnus spacecraft completed it’s final test mission under the C.O.T.S program with a fiery end during re-entry to earth’s atmosphere.  Following a week delay because of an issue during the initial attempt to dock the rest of the mission was very successful with all the cargo being offloaded and trash that was no longer needed being placed in the vehicle.  Orbital are now gearing up for the first of eight Commercial Resupply mission’s under the $1.9 billion contract awarded by NASA, currently scheduled for the end of the year.

ATV-4 completes mission
The fourth Automated Transfer Vehicle Albert Einstein completed it’s mission to the ISS this week, having delivered seven tonnes of cargo to the complex and having been docked for four months the vehicle un-docked from the Russian Zvezda module and like the Cygnus vehicle will meet a fiery end when it re-enters the atmosphere later today.

Soyuz TMA-09M relocated
In preparation for the next manned crew to arrive at ISS the Soyuz TMA-09M which brought Fyodor Yurchikhin, Karen Nyberg and Luca Parmitano was moved from the Rassvet mini-research module to the port freed up on Zvezda following the ATV un-docking.

Typically three members of the current crew leave the station and land before the next three members of the crew launch, however because of the Olympic torch event coming up next week this will be the first time since the last Shuttle mission where more than six people will be on the station at the same time.

Next Station Crew arrive in Kazakhstan
In preparation for their launch to the ISS the next crew consisting of Russian cosmonaut Mikhail Tyurin, American astronaut Rick Mastracchio and Japanese astronaut Koichi Wakata arrived at the Baikonur Cosmodrome for their flight on Nov 7.  They will spent the next week preparing for their mission, and following a six hour flight will dock to the station.

The crew will be carrying a replica of the Olympic Torch which will be handed off to Oleg Kotov and Sergei Ryazansky who will then take it outside the space station during a space walk on Nov 9.  The torch will then return with Yurchikhin, Nyberg  and Parmitano when they depart the station Nov 10 and will then be used during the opening ceremonies at the Sochi games in Feb 2014.

Dream Chaser crash lands
During it’s first free flight test the Sierra Nevada Dream Chaser performed perfectly right up to the point where the landing gear deployed, for some reason the left landing gear did not deploy, which caused the vehicle to skid off the runway.

However during the flight Sierra Nevada were able to gather a load of very valuable data from the instrumentation on the craft and verify that it could fly autonomously.  During the landing the craft detected the problem with the landing gear and was able to keep the left wing in the air as long as possible before it finally dropped causing the craft to to skid off the runway.  Sierra announced after the accident the the internal structures in the vehicle had not been damaged during the accident and they were confident it could fly again if need to further validate the design.

Orion spacecraft powered up
The first Orion spacecraft that will fly in space was powered up for the first time this week.  The vehicle which is currently scheduled to fly some time between Sept 18 and Oct 18 2014 was activated to allow testing on the main control computers to begin.

MAVEN readied for launch
NASA’s next mission to Mars the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft is just 16 days away from launch, NASA held a press conference this week to discuss the mission and it’s goals.  Check out the conference here, we will have more news next week.

First Earth-sized Rocky Exoplanet Found
This week astronomers announced the discovery of Kepler-78b a earth sized rocky planet orbiting Kepler-78, however the planet orbits every 8.5 hours making it far too hot to support life.  For more information on the new discovery check out the full article here.

Most Distant Galaxy Discovered
This week astronomers announced the discovery of the most distant galaxy found so far.  The galaxy is seen as it was just 700 million years after the Big Bang, when the universe was only about 5 percent of its current age of 13.8 billion years.

NASA sets Data Transmission record
One of the payloads on the LADEE spacecraft is a Laser Based communication system, during testing NASA set a record of 622 megabits per second. Laser based communications will significantly increase the amount of data that can be transmitted between spacecraft and the ground.
