ULA to trim management by 30%

10:31 pm

The competition heats up: In order to make itself more efficient and competitive, ULA has decided to cut its management by 30%.

ULA CEO Tory Bruno has said ULA must shrink to remain successful under reduced U.S. military budgets and with Elon Musk’s SpaceX (Space Exploration Technologies Corp.) being certified to compete against ULA for national security mission launches. “To achieve that transformation, we are reducing the number of executive positions by 30 percent and offered a voluntary layoff for those interested on the executive leadership team,” said ULA spokeswoman Jessica Rye. “It is important for ULA to move forward early in the process with our leadership selections to ensure a seamless transition and our continued focus on mission success.”

This news should be looked at in the context of a proposed Senate bill that requires the Air Force to significantly cut funding to ULA.

Not only would the bill cut an annual $1 billion payment from the Air Force to ULA, it would put severe restrictions on the number of Russian engines ULA could use in its Atlas 5, which in turn will limit the number of launches the Air Force can buy from the company.

LightSail deployment scheduled for Tuesday

7:54 am

Assuming all goes well with the orbital preparations today, LightSail will perform its test deployment on Tuesday at 11:44 am.

If successful, this deployment will achieve several significant engineering firsts, the most important of which will be to have demonstrated that a cubesat can be used for such a task. Proving that fact will increase their commercial usefulness for future space endeavors.

India’s spaceplane prototype to fly by August

10:16 am

The competition heats up: The first test flight of India’s prototype scaled-down version of a reusable spaceplane is expected by late July or early August at the latest.

It appears the Modi government is accelerating development of this mini-shuttle, which is essentially India’s version of Sierra Nevada’s Dream Chaser. If they build it first, it will mean they will have the chance to grab the business that Sierra Nevada has been hoping to grab.

New flights from SpaceShipTwo will likely not happen for years

10:09 am

In the heat of competition: A variety of unnamed sources are saying that Virgin Galactic’s new SpaceShipTwo will will likely not fly for years.

This quote is especially telling:

As to when that commercial service might actually be ready, one former Virgin Galactic employee told Newsnight: “I can’t say whether it will be two years or whether it will be five… They have a huge, huge, way to go.”

So is this quote from Doug Messier, quoted in the article:

“This program’s claimed four lives already and it’s had four powered flights and they haven’t gotten anywhere near space in 10 years.”

When summed up, as Messier does, Virgin Galactic’s effort sure sounds disappointing, doesn’t it?

ESA and Airbus Safran agree on deal to build Ariane 6

4:56 pm

The competition heats up: Airbus Safran have come to an agreement with the European Space Agency on building Ariane 6, Europe’s next commercial rocket.

The key part of the deal is that ESA and Arianespace will be ceding ownership of the rocket to Airbus Safran.

The French government is likely to approve the sale of CNES’s 34-percent stake in the Evry, France-based Arianespace launch service provider to Airbus Safran Launchers at about the same time as the Ariane 6 development contract is signed.

With that sale, Airbus Safran will control Arianespace, which means they will also own the rocket they are building for Arianespace. This is fundamentally different than the situation with Ariane 5, which Airbus built for an Arianespace owned and run by the many-headed ESA. The result was a bloated government-run operation that never made a profit.

Now Airbus will own it instead. They have already indicated that they will trim the costs at Arianespace. More importantly, with ownership will come the freedom to compete effectively in the much more competitive launch market created by the arrival of SpaceX. No need to get permission from ESA to do things.

Rosetta team proposes landing on comet to finish mission

4:14 pm

Rather than simply turn off the spacecraft when its funding runs out at the end of 2015, Rosetta’s science team have proposed that the mission get a nine month extension, during which they will slowly spiral into the comet and gently land.

Their proposal is similar to what American scientists did with their NEAR spacecraft, which hadn’t been designed to land on an asteroid but was successfully eased onto the surface of Eros, where it operated for a very short time.

ALMA detects a solar flare on Mira 420 light years away

9:17 am

Mira A and Mira B

The just completed ALMA (Atacama Large Millimeter/submillimeter Array), a collection of 66 antennas located in Chile, has snapped a picture of the variable star Mira with its companion star, detecting details on the primary’s surface, including evidence of a solar flare.

Mira is a star with a mass like our Sun’s, but near the end of its life having evolved into a red giant that is shedding its outer layers. Being able to track its behavior with this kind of detail will allow astronomers to better hone their theories about the life and death of stars, including our own.

Another major image release from Rosetta

9:34 am

Time for many cool images! The Rosetta science team has just released to the public another batch of images from its navigational camera.

The 1776 images cover the period between 23 September and 21 November 2014, corresponding to Rosetta’s close study of the comet down to distances of just 10 km from the comet centre – 8 km from the surface – and the images taken during and immediately following the landing of Philae on the comet.

You can browse through them at your leisure, making your own discoveries if you have a sharp eye and know something about planetary geology.

A solar system like our own, but when it was a baby

9:28 am

Astronomers have discovered a very young 15 million year old star only 360 light years away that has a debris disk about the size of our solar system’s Kuiper Belt.

The ring is about the same distance from its parent star as the Kuiper belt is from the Sun, and receives roughly the same amount of light. Its blue-grey colour hints that it could consist of ices and rocky silicates such as those found in the Kuiper belt, says lead author Thayne Currie, an astronomer at the Subaru Telescope in Hawaii, which is run by the National Astronomical Observatory of Japan. “This is absolutely the closest example we have of a young Kuiper belt,” he says.

The best part of this discovery however might be how it was made, by using a new instrument on the ground-based Gemini telescope on Mauna Kea in Hawaii.

The instrument, which is part of the Gemini South telescope in Chile, uses a disk called a coronagraph to blot out the glare of bright stars. That allows it to take multi-wavelength pictures of faint, orbiting planets and debris disks around stars, by recording near-infrared light from the parent star as it scatters off the debris. The researchers discovered the disk around HD 115600 fewer than 6 months after the GPI began operation. A similar instrument, known as SPHERE, began operating in May 2014 on the European Southern Observatory’s Very Large Telescope in Chile and has also begun to make discoveries.

Assuming protesters don’t force Gemini to close, we should be getting a lot more exoplanetary discoveries from it in the coming years.

Russian rocket engines ready for shipment to U.S.

9:14 am

The competition heats up: An engine that Russia has developed for its Angara rocket has now been tested and is ready for shipment to the U.S. for use in the first stage of Orbital ATK’s Antares rocket.

This new engine will replace the refurbished Soviet-era engines Antares had been using previously that had caused the October launch failure. Note also that since Antares is not a military rocket, it does not fall under the Congressional ban for Russian engines that limits their use on ULA’s Atlas 5 rocket. As the article notes,

On Jan. 16, 2015, RKK Energia, parent company of NPO Energomash, announced that it had reached an agreement with the American company Orbital Sciences Corporation, OSC, on the export of RD-181 engines for the first stage of the Antares rocket, thus replacing the NK-33 engines previously used on the launcher. The contract, worth around $1 billion, was actually signed and ratified by the Russian government in December 2014. According to the document, a total of 60 RD-181 engines would be delivered to OSC beginning in June 2015.

This deal means that Antares will likely be back in business soon, though it will still be dependent on Russian-built equipment, which carries its own risks. It also means that Orbital ATK will not be able to sell Antares to the U.S. military, limiting its marketability.

It looks like the Moon!

9:03 am

craters on Ceres

Cool image time! Dawn has now swooped down to 3,200 miles, and provided a very nice image of the cratered surface of Ceres. Though it does appear to resemble the Moon, there are some differences that come to mind if you take a close look at the full resolution image. The surface appears smoother. All of the craters appear worn or eroded or less rugged. Also, there are no mountains. The terrain resembles the Moon’s lowlands or maria, but more so.

Note that the region in this picture is tantalizingly close to the double bright spot, but does not include it. Because Dawn is still easing its way into its first survey orbit of 2,700 miles elevation, it only takes pictures when it stops firing its ion engine, which it is doing almost all the time to get where it wants to be. Thus, they apparently only had time for this image.

The spacecraft enters its mapping orbit on June 3. Expect some cool images, including the first good images of the double bright spots, shortly thereafter.

Russian rocket now garden furniture in England

5:36 pm

A British businessman has purchased a discarded Russian rocket and installed it in his garden as decoration.

Almost 40ft long and weighing five tonne, the rocket was first flown in 1991 after being built by the Russians in collaboration with NASA at a cost $10 million. For ten years it held the record for the fastest ever made-made machine before it was jettisoned as archaic.

Somehow it ended up at a car auction at South Marston where it was spotted by Mr Sweet while checking out vintage motors. Mr Sweet, who runs the Cirencester-based computer company Zycko, said: “I saw it for sale at a car auction and decided to buy it, not really knowing what I was going to do with it.”

I am curious how the rocket had ended up being owned and offered for sale by a UK company that “specializes in car restorations.” I also wonder if this might be a major new profit center for the struggling Russian rocket industry.

X-37B orbit uncovered

5:27 pm

Space hobbyists have pinpointed the classified initial orbit of the recently launched X-37B.

Observers this week spotted the craft flying overhead in a 194 by 202 mile orbit (312 X 325 km), tilted 38 degrees relative to the equator. That perch is lower than previous X-37B missions and the inclination is lower, too.

“OTV 4 entered the lowest initial altitude of the program,” said Ted Molczan, a respected satellite observing hobbyist. “The ground track nearly repeats every 2 days. Frequently repeating ground tracks have been a common feature of the program. This could be an indication of a surveillance mission, or it may offer some operational advantage I have yet to figure out.”

Not much else has as yet been uncovered.

New Images of Pluto from New Horizons

5:20 pm

Pluto in mid-May

Cool image time! New images taken by New Horizons of Pluto in mid-May have begun showing faint details of the planet’s surface.

“These new images show us that Pluto’s differing faces are each distinct; likely hinting at what may be very complex surface geology or variations in surface composition from place to place,” said New Horizons Principal Investigator Alan Stern, of the Southwest Research Institute in Boulder, Colorado. “These images also continue to support the hypothesis that Pluto has a polar cap whose extent varies with longitude; we’ll be able to make a definitive determination of the polar bright region’s iciness when we get compositional spectroscopy of that region in July.”

These images also suggest vaguely that Pluto might not be entire spherical, but I wouldn’t put much money on that speculation. We will know for sure in just a few more weeks.

NSF to help fund the development of implantable antennas

1:47 pm

What could possibly go wrong? The National Science Foundation (NSF) is providing funding for the development of an implantable antenna for health care, including the possibility for “long-term patient monitoring.”

The project is being financed in collaboration with the National Research Foundation of Korea to create a high frequency antenna that can be permanently implanted under a person’s skin. “Antennas operating near or inside the human body are important for a number of applications, including healthcare,” a grant for the project said. “Implantable medical devices such as cardiac pacemakers and retinal implants are a growing feature of modern healthcare, and implantable antennas for these devices are necessary to monitor battery level and device health, to upload and download data used in patient monitoring, and more.”

The grant said that an implantable device could be used for “long-term patient monitoring” and “biometric tracking,” or using technology to verify a person’s identity.

Without any doubt there are many very useful applications for such an implantable device. Monitoring battery life on pacemakers is an obvious one. There will be a problem, however, if anyone but the patient can do the monitoring. I can see too many possible misuses occurring should it be in anyone else’s hands. At a minimum, there are big privacy concerns.

Criminal charges against Russian workers who caused Proton failure

10:50 am

The three Russian technicians and their supervisor whose sloppy work caused the spectacular 2013 crash of a Proton rocket immediately after launch have now been indicted on criminal charges and will face trial.

According to investigators, Grishin, Nikolayev and Gudkova in 2011 were tasked with installing the angular rate sensors on the Proton rocket that are responsible for yaw control. “As a result of their violation of technical discipline envisaged by engineering and technological documentation, these sensors were installed incorrectly / at 180 degrees from their correct position/,” Markin said.

The installation error accounted for the vehicle’s wild trajectory, causing its crash and destruction. During the investigation, Grishin and Nikolayev partly admitted their guilt in committing the crime, he said.

In his turn, Nasibulin guided by the fact that over a long time no violations had been found during the installation process and also amid the job cuts withdrew the control operation from a respective list. He did not monitor the process and the sensors were installed without the due control.

Note that they didn’t sabotage anything intentionally. They only did bad work. In the U.S. such incompetence would certainly get them fired, but no one would dream of prosecuting them under these circumstances. It appears that Putin’s government has decided to make them scapegoats and an example to everyone else: Do your work right or else!

Along these lines, Russian government officials have also indicated they are considering imposing fines on manufacturers for any future failures or delays.

Both the criminal indictments and the fines would surely work to prevent further disasters. They will also work very effectively in preventing any risk-taking or innovation from anyone. Who wants to build something new and untested if there is a strong possibility its failure will get you in prison?

Do not expect much creativity from the Russian aerospace industry in the coming years.

Solar sail experiment stymied by software crash

10:14 pm

The Planetary Society’s LightSail solar sail test mission, launched as a secondary payload on last week’s Atlas 5 X-37B launch, has fallen silent because of a software problem.

The communications problem occurred before the mission could achieve its main engineering goal of testing the deployment of the solar sail. They still hope to regain communications, but time is limited as the cubesat is in a low orbit that will decade relatively quickly.

New world record for longest hoverboard flight

9:04 am

The inventor of a hoverboard designed to be flown by an individual standing on the board has set a new world record, flying more than 900 feet.

Canadian inventor Catalin Alexandru Duru traveled a distance of 275.9 m (905.2 ft) on a propeller-based hoverboard he created himself. The machine was reportedly designed and built over the course of 12 months. “I wanted to showcase that a stable flight can be achieved on a hoverboard and a human could stand and control with their feet,” Duru is quoted as saying to Guinness World Records, which has recognized the feat.

Video of the flight is below the fold. It appears he essentially scaled up a drone to carry human weight.

The Russian investigation into Progress failure stalled?

8:47 am

Internal disagreements appear to be hampering the investigation into the Progress launch failure in late April.

The investigation had been leaning to pinning the failure on the disintegration of the Soyuz third stage oxygen tank. Others, however, are now claiming that the disintegration itself was caused by an improper separation of Progress from the rocket. The result is that the investigation has delayed the release of its findings.

UAE establishes space agency

8:31 am

The competition heats up: The United Arab Emirates (UAE), in conjunction with its goal to send an unmanned probe to Mars, has announced the formation of its own NASA-like space agency.

Reading the long official press announcement at the link above will make you realize that a lot of this is public relations fluff being pushed by the UAE’s sheiks. Stripping that away, what I find left is mostly a program to educate students.

Corruption in the Russian space industry

8:52 am

A slew of stories in the Russian press today illustrate again the deeply ingrained problems that country has, both in corruption and in its ability to produce a quality product.

The last story describes the overall scale of the corruption, which is not confined just to the space sector, but can be found in many industries. The aerospace industry just happens to be the most visible outside Russia, and thus the most embarrassing. Yet,
