A lot has been happening this week in Space

ISS Coolant Failure
This week one of the two coolant systems on the station shutdown when a component reached a preset temperature limit.  While not posing an immediate danger to the crew on-board the shutdown did require that NASA shutdown non-critical systems on the station to ensure that nothing overheated.  Engineers are still determining what needs to be done to resolve the problem which may include a spacewalk.

Proton Launches Mobile Broadband Satellite
Last Sunday a Proton rocket lifted off from Kazakhstan carrying a powerful broadband communication satellite for London based Inmarsat, this launch marks the beginning of a next-generation fleet for the company.

Brazilian Satellite lost
A joint Chinese/Brazilian satellite was lost this week when the Long March 4B rocket failed to deploy it to the correct orbit, initial reports heralded the launch as a success but were quickly replaced with the launch failure notification.  The $250m earth observation satellite was the fourth in a series of joint adventures between the Chinese and Brazilian governments.

NASA Curiosity News
The Curiosity Rover continues to return fascinating news from the red planet.  Recent results from the ancient lakebed that it is exploring show that Mars could have been habitable in the past.  The rover is now looking for areas where erosion could have uncovered layers of martian soil that could contain organic components.

In related news NASA announced that the rover had fired it’s laser more then 100,000 times while on the planet surface.

Mars One sending Lander to Mars
Mars One who made news last year when they announced they planned to settle people on Mars by 2023 were in the news again this week.  They announced plans with Lockheed Martin and Surrey Satellite Technology Ltd to develop and launch a privately funded lander to explore Mars.  Check out the full press release here.

Gaia Spacecraft enclosed in Soyuz fairing
The European Space Agencies Gaia spacecraft moved a step closed to it’s 12/19 launch this week as it was enclosed in it’s Soyuz launch fairing.  For more information on the mission check out the mission page here, we will post more information on the mission next week assuming a successful launch.

Launch pad 39A news
The commercial leasing of launch pad 39A moved a step closer following a decision by the Government Accounting Office regarding a protest by Blue Origin about the agencies fairness in the search for a long term tenant.  The launch pad currently costs NASA approximately $100,000 a month to maintain, as they no longer need the pad for future NASA missions and 39B will be used for SLS this money can be better used within the agency.

Following the GAO decision NASA announced on Friday that it has selected the SpaceX proposal and will now begin negotiations with the company regarding the lease of the launch complex. During the negotiation process NASA are not allowed to released any further information. Once the deal has been finalized we will post any additional information that is made available.

This week scientists announced that Jupiter’s moon Europa may erupt with fleeting water plumes that are more then 20 times the height of Mount Everest.

If confirmed scientists believe these could provide a way of detecting signs of life in the underground ocean that is believed to be under the thick ice of the moon.  Due to it’s proximity to Jupiter scientists believe that the core of the moon is hot enough to maintain a liquid ocean via thermal vents just like in the depth’s of earth’s oceans that surprised scientists when they discovered a vast variety of life.

To learn more about the Jovian moon, scientists analyzed ultraviolet images of Europa taken by the Hubble Space Telescope in November and December of 2012 as well as older images taken by Hubble in 1999. They concentrated on finding hydrogen and oxygen, the elements that make up water.

First Orbital Cargo Mission to launch
Orbital’s first mission under there Commercial Cargo resupply contract is preparing to launch next week 12/18.  Roll out to the launch pad is expected on Monday once any last minute items have been loaded into the Cygnus spacecraft.  Orbital are currently contracted for eight flights to the station.

Morpheus Lander first free flight successful
A prototype lander that could be used for future missions to an asteroid or other planetary object completed it’s first free flight test this week.  Following a number of tether tests to ensure all systems worked the vehicles was shipped to Kennedy Space Center so that it could begin free flight tests.  The first test occurred this week and accomplished it’s goals, check out the video of the flight here.

Titan Flyover
This week NASA released a new video based on data from the Cassini spacecraft that shows a flyover of the lakes on Titan.  Check out the full release and video here.

China’s Lunar Rover scheduled to land today
The Chang’e-3 Lunar Rover is scheduled to land on the moon today, we will post more information next week once it is available on the success or failure of the landing and any other news from the event.
