The competition heats up: SpaceX has now scheduled the pad abort test for its manned Dragon capsule for no earlier than May 5.
This is three days later than previously scheduled, though the previous schedule was quite tentative. This announcement is more firm.
Fascists: In order to protest what they preceive as a hostile environment on campus for minorities, protesters blocked access to the school so that minorities could not attend classes.
Up to 50 students gathered and prevented foot traffic through the gate. On multiple occasions, students, including minorities, tried to break through so they could attend class. In response, the protesters violently attacked them. Three assaults were reported during the protest. The University of California Police Department (UCPD) at Berkeley did not take action against the protesters, despite the fact that they acknowledged that protesters were breaking the rules and potentially committed crimes.
You can’t make this stuff up. To highlight oppression these fascists impose oppression. According to the article, the protest only ended when students teamed up and “bull-rushed” the protesters in order to get to their classes.
Cool image time! Images taken two minutes apart by Rosetta have captured the emergence of a new jet on Comet 67P/C-G.
The two images released today show the remarkable onset of such a jet for the first time. They were taken on 12 March from a distance of 75 kilometres. In the first image, obtained at 07:13 CET, several rays of dust jets frame the upper, illuminated side of the comet. The dark underside shows no such features. Two minutes later, the picture has changed: a spectacular new jet has emerged on the dark side, hurtling dust into space and displaying a clearly discernable fine structure.
This was the first jet observed in a shadowed area, and the scientists think this jet might have started because it was just before dawn there.
An evening pause: Time for a bit of silliness.

Notice the pattern. These predictions are all negative, expressing doubts and having no faith in the possibilities of what humans can achieve. Use this as a guide when you hear comparable negative predictions today. As someone once said, “When a scientist says something is impossible it just means it will take a little longer.”

Lots of interesting details describing the entire first stage landing attempt. Two interesting facts: 1. The barge was not seriously damaged by the landing crash and will be ready for the next attempt. 2. It appears they will try for a barge touchdown again instead of on land.
Another worker strike has broken out at the new Russian spaceport at Vostochny by workers who say they have not been paid their wages.
The strike itself is not the significant fact here. The significant fact is that even though the project has been under the close supervision of Putin himself since September, the wages were still not paid. Supervisors have been pocketing wages even as very high Russian officials have been publicly demanding that they get the construction back on schedule. And this story suggests that they continue to do so.
The entire situation implies a very extensive level of corruption at all levels of the Russian infrastructure, something that will make it very difficult for them to accomplish much in their future efforts in space.
The competition heats up: Japan’s space agency has announced plans to send an unmanned lander to the Moon, as early as 2018, as part of a longer range plan to explore Mars.
They also intend to use their new Epsilon rocket to launch it.
Gee, I wonder if the successful efforts of India and China to send probes to both the Moon and Mars had some influence on this decision.
Cool image time! As Dawn’s orbit around Ceres has slowly brought the spacecraft up over its north pole and towards its daylight side, it has now become possible to once again spot the giant asteroid’s bright spots.
The science team has also released a very short animation that shows Ceres rotating below it with these bright spots coming into view.
The builders of the Thirty Meter Telescope have temporarily extended the suspension of construction originally demanded by Hawaii’s governor.
The tone of the article, especially the comments by the governor, suggests that the state is accepting the reality that they have no legal right to stop construction, and are making that fact very public. Instead, the govenor is now beginning the public relations campaign to make construction possible despite the protests, including negotiating some other givebacks to the protesters to shut them up. Sadly, those giveback appear to be the decommissioning of some other working telescopes as well as some increased restrictions on access to the mountain by the public.
An evening pause: The violin player, Daniil Bulayev, is especially impressive, being only 8 years old.

You can’t make this stuff up. A giant welding machine, built for NASA’s multi-billion dollar Space Launch System (SLS), needs to be rebuilt because the contractor failed to reinforce the floor, as required, prior to construction.
Sweden’s ESAB Welding & Cutting, which has its North American headquarters in Florence, South Carolina, built the the roughly 50-meter tall Vertical Assembly Center as a subcontractor to SLS contractor Boeing at NASA’s Michoud Assembly Facility in New Orleans.
ESAB was supposed to reinforce Michoud’s floor before installing the welding tool, but did not, NASA SLS Program Manager Todd May told SpaceNews after an April 15 panel session during the 31st Space Symposium here. As a result, the enormous machine leaned ever so slightly, cocking the rails that guide massive rings used to lift parts of the 8.4-meter-diameter SLS stages The rings wound up 0.06 degrees out of alignment, which may not sound like much, “but when you’re talking about something that’s 217 feet [66.14 meters] tall, that adds up,” May said.
Asked why ESAB did not reinforce the foundation as it was supposed to, May said only it was a result of “a miscommunication between two [Boeing] subcontractors and ESAB.”
How everyone at NASA, Boeing, and ESAB could have forgotten to do the reinforcing, even though it was specified in the contract, baffles me. It also suggests that the quality control in the SLS rocket program has some serious problems.
Update: The original story at Space News that I originally linked to disappeared sometime in the next week, and was replaced with a slightly more detailed and more positive story, now linked above.
After a successful launch three days ago Dragon successfully berthed with ISS on Friday, bringing 4,000 pounds of cargo, including an Italian-built expresso machine designed to work in weightlessness.
The competition heats up: Sierra Nevada has signed a new development agreement with Germany in connection with its Dream Chaser reusable mini-shuttle.
The agreement does not appear to involve any money and thus is largely symbolic. Nonetheless, it shows again that Germany is interested in having Dream Chaser built, and is throwing its support behind the manned spacecraft.
After four years in orbit and with its fuel gone, Messenger is now expected to crash into the surface of Mercury on April 30.
The Russian government has decided to delay from 2018 to 2020 the first manned launch from its new spaceport at Vostochny because an earlier launch would require them to use equipment they expect to retire anyway.
While the construction problems at Vostochny might be a factory in this decision, I also believe there is truth to the claim above. If they launch in 2018, they will probably have to use the Soyuz rocket to launch crews into space. By 2020 they plan to have Angara completely operational, and will be ready to retire Soyuz. Why build the infrastructure for Soyuz when you plan to retire it in only a couple of years anyway?
The delay however indicates a more fundamental problem with the Russian top-down authoritarian culture. It shouldn’t take them this long to get Angara operational. The rocket was conceived shortly after the fall of the Soviet Union in the early 1990s. They’ve had almost a quarter century to build it. Even though they’ve only just done the first two test flights, there is no justification for it to take another five years to get all the configurations of the rocket flying.
If they want to compete on the world market, they are going to have to work faster than this. A competitive private company, rather than delaying the launch, would have pushed Angara to be ready sooner so that the the launch could happen on time, with Angara. That the Russians seem unable to do this indicates that they will not be very competitive in the coming decades.
An evening pause: A classic comedy scene from Woody Allen’s Annie Hall (1977). What especially makes the scene work is how realistic he portrays what it was like to stand in a movie line in New York in the 1970s.

Cool image time! The Dawn science team has released its first new images as the spacecraft begins its slow journey from Ceres’ night to day sides.
The images are looking down on the giant asteroid’s north pole. They have also released a short animation where they stitch together the images, allow us to see Ceres rotate under the spacecraft.
The competition heats up: After its second attempt this week to land its first stage on a barge in the Atlantic, SpaceX is now considering landing their next attempt on the ground.
This shouldn’t be a surprise. The reason they have been landing over the ocean in these initial tests was for safety. The last two landings however had demonstrated that they can reliably bring that first stage back accurately and precisely. Since they have the ability to destroy the stage should it go off course, it seems reasonable to shift to land now and simplify their challenge.
