Antares failure cause pinpointed
A report from Orbital ATK has confirmed that it was a failed turbopump in the Russian first stage engine of its Antares rocket that caused the rocket to explode just after launch in October.

The footage below is high resolution. Watch how the rocket comes in to the barge. It is once again astonishing that the rocket hits the target, but it is coming down very fast, and not very vertical. Like the Grasshopper tests, they need to slow it down more just before landing.
The competition heats up: SpaceX has successfully launched another Dragon freighter to ISS.
We await word on whether the first stage was able to successfully land vertically on a barge in the Atlantic.
Update: Musk reports that the first stage landed on the barge but “too hard for survival.” Expect some interesting video to follow. I have posted SpaceX’s video of the launch below the fold. Beginning at about 22:45, after first stage separation, you can see it maintain a vertical orientation as it begins its descent.

Link here. Not only do they intend to recover and reuse the first stage engines, the rocket’s upper stage will be designed with the ability to be refueled and function as a space tug once it has reached orbit.
Ah, the joy of competition. It accomplishes so much, so quickly. I hope we never return to the feel-good era of “international cooperation.”
This article about Paul Allen’s Stratolaunch company notes that the payload the system will put in orbit is likely to be less than originally hoped.
Still to be determined are the manned and cargo craft Stratolaunch will eventually send to orbit or even the International Space Station, Beames said. Muskโs SpaceX, an initial partner, is no longer associated with the venture. The rocket produced by Orbital ATK Inc., which replaced SpaceX, will probably be smaller than the medium-lift vehicle with a 6,000 kilogram (13,000-pound) payload that Stratolaunch had initially planned, Beames said. โI think itโs more likely weโll be targeting a smaller payload class,โ Beames said. โWeโre not announcing anything on that yet.โ
Allen’s company, Vulcan Aerospace, is also demanding that ULA change the name of its new Vulcan rocket, just revealed yesterday.
ULA has announced its plans for replacing the Delta and Atlas 5 rockets, dubbing its new rocket Vulcan.
They plan to develop Vulcan’s first stage first and use it initially on Atlas 5 rockets so they can replace the Atlas 5 Russian engines as soon as possible. Also, they plan to recover the Vulcan rocket’s engines by having them separate from the booster after use and then get captured in a mid-air before hitting the ground. (See the graphic at the link to see a launch profile.)
In watching the press conference, ULA officials made it very clear that they are focusing a lot of their effort on lowering the cost of the rocket.
Today’s Dragon/Falcon 9 launch has been scrubbed due to weather issues.
They will try again tomorrow at 4:10 Eastern.
NASA’s Advisory Council today joined a growing chorus of critics asking NASA to dump Obama’s commitment to send astronauts to an asteroid, or more precisely, to a boulder that NASA has taken from an asteroid.
They want the agency to instead focus on developing ion engine designs in conjunction with an orbital mission to Mars.
The competition heats up: This week SpaceX conducted at Vandenberg a tank test of the booster rocket that will be used for its Dragon in-flight launch abort test later this year.
That they are doing these tank tests at Vandenberg is interesting. I would think the actual abort test would take place at Kennedy, where astronauts will be launched. Either the company is taking advantage of its second launchpad to save time while Kennedy is in use for Monday’s Dragon launch, or they will actually do this launch abort test out west. In truth the test can be done from Vandenberg. The flight path will be different, but the technical requirements will be essentially the same.
Note that this booster is for the in-flight launch abort flight, scheduled at this moment for July, not the launchpad abort test, scheduled at this moment for May 2.
Also, it is interesting to compare the pictures of SpaceX’s Vandenberg launchpad in this article with the pictures I took when I visited Vandenberg two weeks ago. Then, the pad was quiet, with no rocket visible (though it is likely that this booster stage was inside the building being prepared). Now it is quite busy.
The competition heats up: In 2014 more cubesats were launched than during the industry’s first ten years.
Without doubt the concept of cubesats is now taking the satellite industry by storm, mainly because of the advent of new electronic miniaturization. However, the most fascination part of this story was how the concept was born:
In 1999, Puig-Suari met with Bob Twiggs, at the time an aerospace engineer at Stanford University, to discuss ways of getting more student projects into space. โWe had to do something to get more opportunities to launch these things,โ recalls Twiggs, now at Morehead State University in Kentucky. They focused on slimming down the spacecraft, because weight drives up the cost of reaching orbit.
Over lunch at a sandwich shop in San Luis Obispo, Twiggs and Puig-Suari sketched out options on a napkin. They thought hard about the potential capabilities of a 10-centimeter cube with a mass limit of 1 kilogramโthe size and weight of a liter of water. Clad in solar cells, the cube would eke out perhaps a watt of power, enough to power a small computer and a radio: โa Sputnik,โ Puig-Suari says. Back at Stanford, Twiggs found the perfect life-size demonstration model: a plastic box used for storing the insanely popular stuffed animals known as Beanie Babies. A standard was born.
Read the whole thing. The low cost of these tiny satellites is about to revolutionize the entire unmanned space industry.
The competition heats up: In its next launch on Monday, SpaceX will once again try to safely land its first stage on an ocean barge, allowing it to reuse that stage on later flights.
Monday afternoon is certainly going to be an exciting day for space cadets. First, at 4 pm (Eastern) the head of ULA will reveal the design of that company’s new rocket. Then, at 4:33 pm (Eastern), SpaceX will launch Dragon to ISS while attempting to return the first stage safely.
The competition heats up: ULA has scheduled a press conference on April 13, during a space conference, to reveal their design for their next generation rocket to replace the Delta and Atlas 5 rockets.
It is clear that the company is not wasting time getting this new rocket underway. They recognize the competitive threat placed on them by SpaceX, and they are responding correctly.
