The Russians have now fired three executives as a result of their investigation into last month’s Proton launch disaster.
This is in conjunction with hiring an American to take over quality control.
The competition heats up: Sierra Nevada’s engineering test vehicle of its Dream Chaser mini-shuttle completed its first capture carry flight test yesterday.
The test, which saw the lifting body space vehicle lifted by a Sikorsky S-64 to around 12,400 ft above the dry lakebed, follows completion of tow tests earlier this month. … During the Aug 22 flight the Dream Chaser’s flight computer, guidance, navigation and control systems were tested along with its landing gear and nose skid, which were deployed during the sortie.
Curiosity snaps a spectacular image of Mt Sharp as it begins its journey to the mountain’s base.
The rover has already traveled more than a mile. The mountain however remains about five miles away.
On Tuesday NASA released what it calls a new “space exploration roadmap,” outlining the agency’s goals for the human exploration of space over the next few decades.
Normally I’d say, who cares? The space agency puts these kinds of PR roadmaps together periodically. None of them really ever mean that much. And in truth, this particular report doesn’t mean that much either. However, what makes this “Global Plan” interesting and worth mentioning is the participants who wrote it. It seems that NASA and the Obama administration didn’t do it alone.

The competition heats up: Japan’s unveiled its new Epsilon rocket yesterday, scheduled for its first launch next week.
Epsilon is a low-cost, high-performance, solid-fuel rocket co-developed by JAXA and IHI AEROSPACE Co.,Ltd. and designed to launch scientific satellites. Epsilon features the world’s first innovative launch system called “Mobile Launch Control” which allows for built-in checks to be conducted autonomously within the rocket’s system. This allows staff to focus on high-level monitoring, making overall performance very smooth. A spokesman joked that it is so easy to control that staff could monitor the rocket on their laptops while at Starbucks.
In the past Japan has not been very good at building cheap and efficient rockets. We shall see how this one does.
The rover Opportunity has settled into its winter haven on Mars.
The rover’s handlers plan to get Opportunity up onto Solander Point’s north-facing slope before mid-December, NASA officials said. But the golf-cart-size robot won’t hibernate through the winter; rather, it will continue to move about, investigating several different Solander Point outcrops.
The Moon’s dirtiest secret: Does its dust levitate?
This is a serious mystery left over from the Apollo missions which has significant ramifications not only for future research (the dust would interfere badly with any astronomical observatories) but also for any colonies that are eventually established.
The fuel leak that scrubbed yesterday’s launch of India’s GSLV rocket will likely cause at least a week’s delay before another launch attempt.
The launch today of India’s homemade Geosynchronous Satellite Launch Vehicle (GSLV) was scrubbed when a fuel leak was spotted at T-74 minutes.
India has had trouble getting this powerful rocket off the ground successfully, with four previous launch failures. If they succeed this time, however, they will then have the ability to build their own rocket, capable of putting commercial payloads into geosynchronous orbit.
Formation flying in space, without propellants.
Electromagnetic formation flight (EMFF) gets around this propellant problem by turning the satellites in a formation into electromagnets. By using a combination of magnets and reaction wheels, spacecraft in formation can move and change their attitude and even spin without propellant. Satellites can change their polarity to attract or repel one another, turn, or shift their relative positions in any manner that doesn’t require changing the center of gravity for the entire formation.
A prototype is going to be tested inside ISS in the near future.
Works of art: Thirty-six incredible landscapes from video games.
I’ve played none of these games and probably never will, but I can agree without hesitation that the artists who created these visions created something beautiful and epic.
