A buggy software upgrade on November 7 caused Curiosity to spend a week rebooting itself.
A buggy software upgrade on November 7 caused Curiosity to spend a week rebooting itself.
They have switched back to the older software so that Curiosity can continue its journey to Mount Sharp while they debug the upgrade here on Earth.
SpaceX has delayed the next commercial launch of its Falcon 9 rocket by three days.
SpaceX has delayed the next commercial launch of its Falcon 9 rocket by three days, from November 22 to November 25.
It seems they simply wish to give their people some breathing room prior to launch.
China reveals its space station plans.
China reveals its space station plans.
“China Space Station (CSS) will operate in orbit from 2022 to 2032. This period will provide much more opportunities to scientists in China and all of the world after the international space station,” Gu Yidong, president of the China Society of Space Research, said at the American Society for Gravitational and Space Research conference here Nov. 3 – 8. The station’s core module is slated to launch in 2018, followed by two laboratory modules in 2020 and 2022. The outpost will be located in an orbit ranging from 350 kilometers to 450 kilometers above Earth and inclined 42 degrees relative to the planet’s equator.
The article describes in detail their research plans on their station, which sound much the same as the kind of research done on ISS. I suspect this is a bit of misdirection. Their station is clearly designed as a prototype interplanetary station, much like Mir. I believe that any research they do on it will be focused around that fact, which will make that research significantly different that the work done on ISS, which is often not very effective and poorly focused.

After additional tools and parts were sent up on both Progress and Cygnus freighters, astronauts on ISS pinpointed the problem and replaced the failed the “fan/pump/separator”. The faulty unit was brought back to Earth for further analysis in the manned Soyuz craft yesterday.
Of the four U.S. spacesuits on ISS, one is still considered faulty and needs to be replaced, which will happen with the next Dragon flight expected sometime in February 2014.
Two Russian workers were killed and several injured last week while cleaning out a rocket tank at a Russian spaceport.
Two Russian workers were killed and several injured last week while cleaning out a rocket tank at a Russian spaceport.
The article says that the accident occurred because of a failure to follow safety regulations, which suggests that the quality control issues in Russia’s space industry still exist.
A fourth engine burn has put India’s Mangalyaan probe back on course.
A fourth engine burn has put India’s Mangalyaan probe back on course.
The unexpected abort during the previous burn occurred because engineers were testing the primary and secondary electrical coils that operate the engine’s valves.
During the firing on Monday morning, the team was trying to use both the primary and the redundant coils together as part of a trial. However, there was no fuel flow in this mode and the orbiter could not pick up the required velocity or reach the desired higher orbit. … A senior engineer involved in the process said, “Both the coils are working independently (but not if they are switched on together.)
Today’s burn demonstrated that nothing on the spacecraft has actually failed. As expected, simultaneous use of the two coils will no longer be attempted.
A Proton rocket successfully launched a Russian military satellite today.
The competition heats up: A Proton rocket successfully launched a Russian military satellite today.
This is Proton’s the third successful launch in a row since July’s spectacular launch crash. It seems they have straightened out their quality control problems, for the moment.
Lunar Reconnaissance Orbiter inaugurates a new website of its images of the landing or impact sites of every human vehicle to arrive or crash on the Moon.
Lunar Reconnaissance Orbiter inaugurates a new website of its images of the landing or impact sites of every human vehicle to arrive or crash on the Moon.
I found the site because they have a new release of images of the impact crater produced when Ranger 7 hit the Moon on July 28, 1964.

India’s Mars Orbiter Mission experienced its first technical problem during an engine burn today.
As scientists tried to increase the speed of the satellite as it orbited Earth Monday, the flow of fuel to the craft’s main engine stopped. Backup thruster engines kicked in to keep the speed up and help raise the spacecraft’s orbit, but the satellite’s incremental velocity dipped, the Indian Space Research Organisation said.
The spacecraft was unable to reach the desired orbiting height of 100,000 kilometers. The satellite is currently orbiting at just over 78,000 km above Earth and scientists have now altered the mission plan to include an additional engine firing Tuesday to help it reach the correct height and incremental velocity of 130 meters a second.
Engineers seem confident that the spacecraft’s back up systems will be able to pick up the slack.
GOCE has returned to Earth, breaking up somewhere over Antarctica, Siberia, or the Indian or Pacific Oceans.

No damage from any pieces has been reported, which isn’t surprising considering the areas it might have come down.
