This week in space…
SpaceX causes a stir and has another delay
Last Saturday SpaceX caused quite a stir on the Internet when they announced there would be no live web-cast of the Orbcomm OG2 launch attempt that evening. A spokesperson for SpaceX said they had been planning to move away from web-casting because launches had become so routine. The news of the media “snub” was soon all over social media, with a number of commentators saying the the only routine thing so far was delays.
The Saturday evening attempt was aborted due to inclement weather, they were re-scheduled for Sunday evening at which time it was announced they would have a web-cast. However during the count down they found a which required additional analysis and scrubbed again, they then rescheduled for Tuesday but in the end needed more time. The launch is now expected to be in July due to range maintenance work that had been delayed to allow SpaceX to launch in the first place.
We now have to ask is SpaceX moving too quickly in their manufacturing which is causing the delays due to leaks? And how will they be able to meet there stated goal of ten more launches this year?
In separate news these delays are starting to effect Orbcomm financially as they budgeted a certain amount of revenue from the OG2 fleet and with each delay that revenue opportunity grows smaller.
Orbital Cygnus Launch delayed
To allow engineer’s more time to perform detailed analysis of the AJ26 engines on the Tauraus scheduled to launch the next Cygnus spacecraft to the ISS Orbital announced that the Orb-2 flight would not flying before July 10th.
The spacecraft was originally scheduled to launch in May but had to be rescheduled after delays to the SpaceX CRS-3 mission, then because of a AJ26 engine test failure at NASA Stennis Space Center. Orbital elected to delay the launch to allow engineers time to investigate the failure and ensure the other engines would not be effected by the same issue.
Curiosity Rover achieves mission milestone
NASA newest rover Curiosity celebrated it’s first Martian year on the surface of the planet this year completing on of the mission milestones. The rover has achieved much already but there is planet more to go, however engineers have noticed that the wheels have taken a lot more damage than expected, they are currently working on ways to avoid the sharp rocks that have been causing the damage.
Meanwhile elsewhere on Mars the Opportunity Rover still continues to operate more than 10 years after it arrived for a 90 day mission.
And lets not forget that there are currently two NASA orbital spacecraft at Mars and another will be joining them in less than 100 days. Mars Reconnaissance Orbiter and Mars Odyssey are currently in orbit and MAVEN is on route.
Final ATV moves closer to launch
The final European Automated Transfer Vehicle (ATV) named Georges Lemaître has been integrated with its Ariane 5 launcher, scheduled to launch later this summer the vehicle is due to deliver 2600kg of supplies. The ATV vehicles utilize an automated docking process like the Progress vehicles and will attach to the Russian segment of the station. Once unloaded the crew will store any trash they no longer need which will burn up in the atmosphere with the vehicle at the end of its mission.
Another potential habitable world found
Astronomers announced they have found a potential habitable world in the Gliese 832 system just 16 light-years away. The planet Gliese 832c is a “super-Earth” planet which is at least five times as massive and orbit’s the star every 36 days, however because Gliese 832 is a red-dwarf star the planet gets about as much energy from the star as we do making it a very good candidate to support liquid water on the surface.
We more and more powerful telescopes coming on line over the next decade the number of planets found is likely to increase significantly and we will also be able to learn a lot more about these planets.
CoRoT Planet Hunter goes offline
The French COnvection, ROtation & planetary Transits (CoRoT) satellite which has been operational for seven years and helped discover 32 confirmed planets with at least 100 more waiting for confirmation.
Opportunity Rover News
With its solar panels their cleanest in years, NASA’s decade-old Mars Exploration Rover Opportunity is inspecting a section of crater-rim ridgeline chosen as a priority target due to evidence of a water-related mineral.
Orbital observations of the site by another NASA spacecraft, Mars Reconnaissance Orbiter, found a spectrum with the signature of aluminum bound to oxygen and hydrogen. Researchers regard that signature as a marker for a mineral called montmorillonite, which is in a class of clay minerals called smectites. Montmorillonite forms when basalt is altered under wet and slightly acidic conditions. The exposure of it extends about 800 feet (about 240 meters) north to south on the western rim of Endeavour Crater, as mapped by the orbiter’s Compact Reconnaissance Imaging Spectrometer for Mars (CRISM).
