Orbital ISS Launched Delayed again

The ORB-2 Cygnus cargo mission to the International Space Station (ISS) has been delayed again due to the on-going investigation into an AJ26 engine failure last month during testing.  The Antares rocket which launches the Cygnus spacecraft uses two of the AJ26 engines on the first stage to orbit.

The new No Earlier Than (NET) date is July 1st, we will prove additional news when available on the launch date/time.

SLS design change could delay first crewed mission

NASA has decided to change the version of the second stage that will be used on the EM-2 crewed mission.  Originally slated to be the Interim Cryogenic Propulsion Stage (ICPS) stage that will be used on EM-1 they have now elected to use the Exploration Upper Stage (EUS) stage that was originally scheduled to debut on EM-3.  Due to this and the NASA Safety Office and Astronaut Office’s requirement that the upper stage complete at least one mission before any crew and be carried on it could mean that EM-3 becomes the first crewed mission for SLS in 2023.

An alternate option may be to add an additional flight between EM-1 and EM-2 which would be used to prove the EUS therefore allowing EM-2 to be the first crewed flight, however additional funding would be needed to achieve that.  At present there are no future details as to the overall impact of the SLS schedule with primary focus on the EM-1 flight in 2017.

Progress M-21M undocks

This week the Progress M-21M spacecraft completed it’s mission to the ISS with a successful undocking and later burn up in the atmosphere.  The cargo vehicle spent 144 days at the station having delivered almost 2,400 pounds of supplies it was then loaded with trash that was no longer needed.  European Astronaut Alexander Gerst tweeted the picture below of the Progress burning up in the atmosphere to conclude it’s orbital mission.

Rosetta Update

The ESA Rosetta spacecraft completed two big burns this week as it entered the final phase of its approach to the Comet 67P/Churyumov-Gerasimenko after almost a decade journey.  Unlike when it a spacecraft approaches a planet Rosetta will not be able to use the gravity of the comet to get into orbit but instead will need to execute a series of burns to precisely match the orbit.

It is currently approaching at a speed of 17,000 kpd (kilometers per day) and is currently less than 300,000 kilometers away. Over the next month and half it will continue to refine the orbit.

Two new exo-planets found around Kapteyn

A team of Astronomers have discovered two new planets around a nearby red dwarf star Kapteyn, which is about 13 light years away in the southern constellation of Pictor.  One of the planets Kapteyn c is considered to be too cold for life because of it’s distance from the star.  However Kapteyn b is within the habitable zone and therefore could have liquid water on the surface.  The planet is estimated to be 5 times the mass of earth, and has an orbital period of 48 days.

Boeing CST-100 News

This week Boeing showcased their CST-100 spacecraft which is one of the spacecraft that is competing for the Commercial Crew contract to deliver astronauts to the ISS.

The spacecraft will be launched by an Atlas 5 rocket and once in orbit will dock to the space station to deliver up to seven people to the station.  During the return the spacecraft will utilize airbags when it lands.

Boeing also indicated that further progress on the CST-100 would depend on them getting a contract from NASA in the CCtCap process which is currently on-going.

AAA Needed on Mars for Curiosity Rover

Rover Wheel DamageThe Mars Curiosity Rover which has been roaming around on Mars for almost a year is starting show ware and tare from the journey so far.

Originally expected to take a year to get to the base of Mt. Sharp the rover is currently half way there and clearly showing signs of damage from the un-yielding rocks as it moves over the surface.

Hmm wonder what the call out charge would be for AAA to replace the wheel, sign me up for that trip.

Russia plans Biggest Rocket since 1960s

The chief of the Federal Space Agency in Russia, Oleg Ostapenko said this week, while visiting Crimea, that they would need to build a super-heavy rocket capable of lifting between 80 to 85 tons to earth orbit in order to realize it’s lunar ambitions.

100 Million Planets may Harbor Complex Life in Milky Way

Scientists from the University of Texas have released findings based on the “first plausible assessment of complex life in the universe using empirical data.”  The findings estimate that there could be as many as 100 million planets in our galaxy that may harbor some form of complex alien life.  The article also says that our galaxy is one of approximately 500 billion in the universe.

The full article can be found here.

Author Note: The estimate of galaxies in this article seems to be very high a factor of 2.5-5 times higher than most other articles or current estimates.

Trillion Dollar Market

This week Planetary Resources released a video, explaining why they believe fuel from asteroids will create a Trillion Dollar market in the future.  Currently satellite operators have to pay for total weight of the spacecraft, including any fuel needed for the life of vehicle.

Check out the video here.

Smoke detected on ISS Tuesday, crew were not in danger

This week smoke was detected on the ISS, in the Zvezda Service Module, requiring flight controllers to initiate emergency procedures to isolate the modules ventilation system while the source of the some was identified.   The crew were never in any danger and the problem was quickly determined to be a heater that was used for water reclamation.  The heater was deactivated, a fan and filter was then setup to clear the smoke.

Kepler Candidate List updated

The NASA Kepler project updated the number of Kepler candidates and confirmed planets from 3,845 to 4,254. There are now up to one hundred potentially habitable worlds in the Kepler candidates, 30 matching the conservative definition of a potentially habitable.

Pluto and Charon news

Pluto has often been considered a binary planet with its largest moon Charon, it now seems that they may both also share a thin atmosphere.  While it is impossible to detect the atmosphere using ground based technology the New Horizon’s spacecraft that is current racing towards Pluto will have the ability to detect it.

We will know more in 2015 after the flyby has been completed and the data is back on earth.

Check out the fall article here.

In a separate article researchers suggest that if cracks are found in the surface of Pluto that could indicate that the interior was once warm enough to sustain an underground ocean.

This week SpaceX sign military agreement, Chinese Astronauts, Chris Hadfield, Opportunity and Kepler keep giving, and much more.

SpaceX

This week SpaceX signed a framework agreement for potential Military launches in the future.  Under the agreement the air force will evaluate the Falcon v1.1 rocket over at least three launches as well as all the processes, procedures etc involved in create the vehicles.  Once the evaluation period is complete SpaceX may have the chance to compete for future launches.

Chinese Launch and Docking

On Tuesday this week three Chinese Astronauts successfully launched to Orbit aboard a Long March 2F rocket, once in orbit the spacecraft made it’s way to the Tiangong 1 space station arriving on Thursday.  Following a successful automated docking the three Astronauts made there way into the station to begin 15 days of work.  During their stay at the station they will perform a manual undock and redock as well as numerous scientific experiments before heading back to earth.

Opportunity News

This week the Mars Opportunity Rover team announced that they believe they have found clay minerals in a rock recently examined by the rover.  The team explained that their presence is an indication that the rock had been altered by long term exposure to water.  Although they have found indications of water since arriving on the planet they explained that this was different because it indicated a neutral pH balance where as previous examples had higher pH balances.

The Rover has been operating on Mars for 9+ years, over 35 times longer than originally designed and recently broke the US distance record on another planetary object.

In this panorama, Solander Point is the near peak on the left of the horizon. It is more than a kilometre away from Opportunity’s current position and the rover would hope to arrive by August

More Kepler planet candidate announced

The Kepler team announced another 503 planet candidates this week, some which may be the right size and distance from their star to support life.

The Kepler team continue to analyze the vast amounts of data they have already received from the four+ years of operations.

The Kepler spacecraft is currently operating in a Point Rest State due to the failure of a second gyroscope that is used to stabilize the craft, and a team has been formed to determine what course of action can be taken to restore some if not all the scientific operations of the Vehicle.

Chris Hadfield announces resignation

This week Chris Hadfield announced his resignation from the Canadian Space Agency after 21 years at the agency.  Chris who recently returned from a six month mission to the space station the last part which was served as Commander, became well known for the amazing pictures that he tweeted from space.

Chris and his family have spent many years in Houston working with NASA and will be returning to his native Canada to enjoy his retirement.
