Mars Opportunity Update

Opportunity Explores Region of Aluminum Clay Minerals  – sols 3657-3662, May 08, 2014-May 13, 2014:

Opportunity is exploring south of ‘Solander Point’ on the west rim of Endeavour Crater. The rover is exploring the region of aluminum-hydroxyl clay minerals seen from orbit.

On Sol 3657 (May 8, 2014), Opportunity collected a Microscopic Imager (MI) mosaic of the surface outcrop, called ‘Ash Meadows,’ then placed the Alpha Particle X-ray Spectrometer (APXS) for a multi-sol integration. On Sol 3659 (May 10, 2014), the rover drove just under 85 feet (26 meters) to the east, approaching a region of extended outcrop as a possible site for clay minerals. Also, Opportunity tested the new two-second spacecraft clock correction sequence. Over the next two sols, the rover collected an atmospheric argon measurement with the APXS and performed two more one-second-clock corrections.

On Sol 3662 (May 13, 2014), Opportunity bumped 7 feet (2 meters) forward to approach an exposed rock outcrop for further in-situ (contact) investigation.

As of Sol 3662, the solar array energy production was 761 watt-hours with an atmospheric opacity (Tau) of 0.621, and an improved solar array dust factor of 0.964. Perfectly clean solar arrays would have a dust factor of 1.0, so the larger the dust factor, the cleaner the arrays.

Total odometry is 24.49 miles (39.41 kilometers).

SpaceX unveils Dragon v2 – Crew Vehicle

2014-05-29_222550
The Dragon V2 spacecraft

This evening Elon Musk unveiled the next version of the Dragon spacecraft designed to take crews to the International Space Station and beyond.  The crewed version of Dragon has undergone quite a transformation from the first version which was hanging above the crowd during the unveiling.  The spacecraft is much bigger then before, has SuperDraco thruster which will serve both as an Emergency Escape System should there be an issue during ride to orbit as a propulsive landing mechanism allowing the crew module to return to land at the completion of it’s mission.  The crew module can carry up to seven passengers and the interior has a very modern looking interface with touch screen technology, with critical functions being available as button’s for emergencies.

The touch screen interfaces with emergency manual button interface in the middle.

During the animation demonstrating the abilities of Dragon V2 we saw the spacecraft docking to the station using the same mechanism that the Space Shuttle utilized.  There was also a cargo Dragon attached to the station when the new version arrived.

Elon also explained that the SuperDraco thrusters were 160 times more powerful than the Draco thrusters that are used to maneuver when in space, there are four pairs on the vehicle and each is isolated so a failure won’t cause problems for the other.  He also revealed that the thrusters were fully 3D printed.

Unfortunately there wasn’t a question and answer time during the presentation and no detailed about when the first flight will be.

Below are more images captured of the unveiling.

Soyuz TMA-13M completes six hour flight to ISS

At 3:57 pm EDT this afternoon the Soyuz TMA-13M lifted off from Baikonur Cosmodrome carrying Russian cosmonaut Maxim Suraev, NASA astronaut Reid Wiseman and European Space Agency flight engineer Alexander Gerst.  Following a successful climb to orbit the spacecraft began a four orbit, six hour journey towards the International Space Station (ISS).

The spacecraft completed docking at 9:44 pm EDT slightly ahead of schedule due to a flawless flight.  A series of leak check were then performed before the hatches were opened at 11:50pm EDT allowing the new crew to enter the station and being there time working and living on the station.

The accelerated docking processing has become the norm for Soyuz vehicles allowing the crews to launch, dock and enter the station within eight hours.  However as was seen in the previous flight the backup plan is also available which results in it taking two days to reach the station instead.

The station is once again back at it’s full six crew member complement and has a busy schedule coming up which includes visits from Progress, Cygnus, ATV and Dragon as well as five spacewalks two from the Russian airlock and three from the US side.

 

Morpheus Lander Night Flight Test

This evening the Morpheus Lander performed it first night flight test to demonstrate the Autonomous Landing Hazard Avoidance Technology (ALHAT)’s ability to function even in the dark.

The initial test was aborted, however following a review of the data the team re-cycled and was able to perform a successful test concluding with a successful landing as designed. We are waiting for word from the team to determine that ALHAT was in control for the whole flight.

At present this is the last of the tests for Morpheus.

SpaceX Dragon completes successful mission

Last Sunday at 3:05pm the SpaceX Dragon capsule successfully completed it’s CRS-3 mission to the International Space Station (ISS) with a splashdown in the Pacific ocean.

Dragon CRS-3 SplashdownLaunched on April 18th aboard a Falcon 9 rocket the Dragon spacecraft, carrying nearly 5,000 lbs of supplies and payloads including two in the un-pressurized trunk, the craft was deployed to orbit following the successful launch.  On April 20th the craft was captured by the station’s robot arm and berthed allowing access to the cargo.  On Sunday the craft was unberthed from the station carrying 3,500 lbs or cargo.  After successfully backing away from the station, later in the day the craft was commanded executed de-orbit burn which concluded with the splashdown.

This was the longest orbital mission so far for Dragon at 29 days, 23 hours and 40 minutes.

On Tuesday the spacecraft arrived at the Port of Long Beach in Southern California where time-sensitive cargo was off-loaded and handed over to NASA, the spacecraft will now travel to the test facility in McGregor, Texas where the rest of the cargo will be off-loaded and handed over to NASA.

On Wednesday it was reported that during the landing there was some water seepage into the spacecraft after the landing, however it doesn’t appear that this caused any issues with the experiments on board.  However due to this event NASA will require resulting from an investigation by SpaceX and any changes needed to avoid this happening again before the next Dragon flight will be approved.

Aerojet Rocketdyne to provide upper-stage propulsion for RELS

True Cost of SLS, Orion Unclear

The Government Accountability Office report on the Space Launch System and Orion spacecraft indicates that NASA has masked the true cost of being the pair by neglecting to say what the system will cost to build for each flight.

So far there are only two missions slated for the combined vehicle and the estimated cost through 2021 is $22 billion.

While I believe NASA needs to have a crewed vehicle for deep space missions it would be interesting to see what SpaceX or another commercial company could create for $22 billion.

SpaceX launch of Orbcomm Satellites targeted for June 11th

SpaceX has re-aligned the next launch to No Earlier Than (NET) June 11th.  The delay were caused by a Helium leak in the first stage that was found during fueling for the Static Fire Test.

This leak was a different location to a leak that delayed the CRS-3 mission, although further details were not available it seems likely that it was around the Composite Overwrap Pressure Vessels (COPV) which are used to pressurize the vehicle.

It is not clear yet if the issue has been repaired but SpaceX are working towards this date and a new Static Fire will be performed at some point before then.

The Planetary Society responds to coverage of ISS statements by Russia

The Planetary Societies Blogger Casey Dreier posted this week a response to all the coverage of the ISS suitation since Russia made statements regarding the status of the station.

Firstly there were two issues in the statements, one relating to the RD-180 engines which has been covered previously and the second relating to the station.

In summary the current operation plan for the station runs until 2020, NASA with the approval of the White House proposed to extend this until 2024, however as of yet none of the other partners had actually signed onto this new plan.  However it was originally thought that Russia were interested in the extension however since the tensions over Ukraine that no longer seems to be be case.

However given that there are over six years left in the current operational plan there is nothing to say the situation won’t change again.

Casey’s full blog article can be found here.

Space station’s Sphere’s use Google smartphone tech

The free-flying Spheres modules on the International Space Station will now be aided by Google’s Project Tango to assist the crew in mundane tasks.  Project Tango is a smartphone project by Google’s Advanced Technology and Projects group which tracks the 3D motion of the device and create a 3D model of the environment around it.

The Spheres modules short for Synchronized Position Hold, Engage, Reorient, Experimental Satellites has been tested on the station since 2003 and with this latest upgrade will be able to perform more functions.

The Spheres project was originally inspired by Star Wars.

SpaceX DragonFly test vehicle revealed

In further SpaceX news this week details of the DragonFly test vehicle became available.  The vehicle will be tested at SpaceX’s McGregor facility and consists of a 7 ton Dragon capsule equipped with eight SuperDraco thrusters, an integrated trunk and up to four landing legs.  The vehicle will be put through a series propulsive landing tests to validate the design and to enable future Dragon vehicles to perform a land based landing.

Further details and a demonstration video can be found here.

Antares AJ-26 engine fails during test

One of the Aerojet AJ-26 main engines for the Antares rocket suffered extensive damage during a test firing at the Stennis Space Center this week.  Before the engine’s can be used for an actual launch they are test fired to verify everything is working correctly.

At present it is not known if this failure will have any impact on the June 10th launch of an Antares carrying the Cygnus spacecraft on it’s next visit to the ISS.

 

Another successful Morpheus Test Flight

Today was a busy day in Florida following on from the successful launch of Atlas 5 this morning another flight occurred a KSC when the Morpheus Lander test vehicle took to the skies for another flight.

This was the first closed-loop ALHAT free flight onboard Morpheus, which basically means the ALHAT operated completely autonomously during the flight.  The ALHAT (Autonomous Landing Hazard Avoidance Technology) allows the vehicle to select the best landing site by detecting the environment and determine where it is safe to land.  This technology will become increasingly important as we send landers further away from earth were making remote corrections during landing is impossible.

Here are some screen captures of the test flight.

Successful Liftoff of NROL-33 aboard Atlas 5

Russia fires back over US Sanctions

This week Russia fire back against US sanctions in two key areas, the first was to spurn NASA’s proposal to extend the life of the ISS through 2024.  The second by announcing plans to block the export of Russia engines for U.S. Military launches.

Given the continued aggression in Ukraine is doesn’t seem likely that these issues will be resolved quickly.  The impact of the station extension won’t be felt for a number of years yet and could well change before then anyway.  The impact on launches could hit home much sooner depending on how many engines ULA have already available.  Although there could be an alternate solution very soon as SpaceX are close to finalizing the EELV certification process which would enable them to compete for military launches.

Bigelow Aerospace BA-330As for the Space Station it looks like it might be time to start looking for a long term alternative and Bigelow Aerospace’s BA-330 solution could be a good option.  If planning started soon there is no reason why a fully operational station couldn’t be in orbit and have crew members living on board well before the ISS concludes it’s operations in orbit.

While Russia hasn’t impacted the crewed launches to ISS yet, if the sanctions continue it could result in the US not being able to access the station, while some believe this is unlikely because NASA are paying for the seats to orbit it isn’t beyond believe that it could happen.

SpaceX Dragon returns this weekend

The Dragon spacecraft currently docked to ISS is expected to depart on Sunday to being it’s return to earth.  Assuming all goes to plan Dragon will be unberthed from the station on Sunday at approximately 9:30am EDT and is expected to splash down in the Pacific Ocean about 6 hours later.

Dragon is the only cargo vehicle currently that has the ability to return to earth allowing critical experiments to be returned for scientists around the world to continue there investigations.  All the other cargo vehicles that visit the station burn up in the atmosphere at the end of there mission.

Shuttle Engines selected for first SLS Launch

This week NASA announced the selection of four veteran Space Shuttle Main Engines (SSME) known as the RS-25’s to be used on the first launch of the Space Launch System (SLS) in 2017.

The SSME’s had been used throughout the 30 year history of the Shuttle Program and with the exception of one flight where a safe Abort to Orbit was needed performed flawlessly during that time.

Unlike the Space Shuttle the engine’s will not be returned after the launch and will be destroyed during re-entry of the first core SLS stage.

Astronomers find Sun’s first sibling

Astronomers announced this week they had detected what they believe to be the first sibling of the Sun.  This star HD 162826 is believed to have been created from the same gas cloud that the Sun is believed to have been created from.  The star is 100 light-years away in the constellation Hercules and isn’t visible to the naked eye, the star is approximately 15% more massive than our Sun.  They have been observing the star for 15 years and have yet to detect any planets orbiting it.

To detect the sibling the Astronomers looked for two identifying features, the first a simliar chemical composition to our Solar System and secondly similar orbit’s around the cetner of the Milky Way galaxy.
