The last two satellites in Russia’s missile warning constellation have failed.

8:55 am

In January the last two satellites in Russia’s ballistic missile warning system shut down, with the first of the next generation replacement constellation not scheduled to launch until June.

“Oko-1 was part of Russia’s missile warning system. The system employed six satellites on geostationary and highly elliptical orbits. The last geostationary satellite got out of order in April last year. The two remaining satellites on highly elliptical orbits could operate only several hours a day. In the beginning of January, they also went out of order,” Kommersant said.

The new generation early warning satellite Tundra was planned to be launched in 2013. However, the launch was postponed several times as the apparatus was not ready to be put into operation, sources in the aerospace industry told the daily.

Increasingly I am reminded of the Cold War, when our competition was the bloated, inefficient, and poorly managed Soviet Union. The communist nation was definitely a threat, as they got a lot accomplished through sheer brute force and determination. Their long term problem was that it was an amazingly inefficient system, guaranteed to eventually fall apart.

Europe test flies its engineering prototype space plane

8:44 am

The competition heats up: Europe today successfully launched and landed its Intermediate Experimental Vehicle (IXV) space plane.

More details here. And here.

As of 9 pm (Eastern) Wednesday the recovery ship was still “hurrying” to reach the ship, which was being held afloat with “balloons.” Update: The spacecraft has been retrieved.

This prototype is not full scale. It is only about 16 feet long, and was built as a testbed. Whether Europe follows up with a full scale version remains completely unknown. I am skeptical, as this program reminds me of many deadend NASA experimental programs like it, used to try out cool engineering technologies as well as provide pork to Congressional districts without any plans to proceed to the real thing. In the case of IXV, the Italians got most of the pork.

Weather 90% go for Falcon 9 launch today

9:14 am

The weather looks almost perfect for tonight’s Falcon 9 launch.

The Falcon 9 will put a solar observation satellite into orbit. While many left wing media outlets will wax poetic about this is Al Gore’s satellite, it is hardly that. It might have been built initially under his misguided idea of creating a propaganda satellite to take daily images of the Earth (images that are essentially of little use for climate studies), DSCOVR has been very carefully redesigned to give it a real purpose, monitoring the solar activity of the Sun and providing a replacement/back-up for ACE, which is now more than a decade overdue for replacement.

The Falcon 9 launch will also attempt again to land intact its first stage on a floating barge. If this attempt succeeds the entire future of space travel will be reshaped.

Plumes and dust surrounding Comet 67P/C-G

11:07 am

Plumes and dust

Cool image time! A new navigation camera mosaic from Rosetta shows both a clear plume rising out of Comet 67P/C-G as well as a “large number of small white blobs and streaks in the image are likely specks of dust or other small objects in the vicinity of the comet.”

The fact that, unlike previously, they did not have to significantly overexpose the image to bring out the plume and dust illustrates the increasing activity at the comet.

NASA safety panel questions safety of SLS

10:47 am

NASA’s safety panel has issued a report questioning the safety of the early launches of the Space Launch System (SLS), partly due to the very low launch rate and the lack of any planned unmanned test flights for the rocket’s upper stage engine.

“The ASAP and the Agency remain concerned about risks introduced in the currently scheduled frequency of SLS/Orion launches, ” according to ASAP’s 2014 Annual Report. “The plan indicates a launch about every 2 to 4 years. This would challenge ground crew competency. The skills, procedures, and knowledge of conducting the launch, mission, and recovery are perish-able. The ASAP believes that an extended interval requires the relearning of many lessons and skills, in contrast to Apollo and Shuttle, which had a relatively steady cadence.”

No space project can accomplish anything with launch rate this slow. Not only does this increase the risk that inexperience will cause errors, the long time gaps make it difficult for the project to get anything done.

And then there is NASA’s idea that it can put humans on this rocket without any previous launch testing of the rocket’s upper stage or the capsule’s life support systems. Why should NASA’s rocket get a pass on this kind of testing when the agency is demanding that the private companies do it?

Rocket tank lands on Brazil farm

10:26 am

Chicken Little report: A propellent tank from an as-yet unidentified rocket landed near a house on a Brazilian farm on December 28.

The pictures at the link are neat, especially since the man in the selfie showing the farmer’s family and the tank in the background looks so much like New Jersey governor Chris Christie.

OSIRIS-REx to get more fuel for its asteroid mission

10:17 am

In what might be a first for the planetary science/engineering community, an unmanned probe, being built to bring samples back from the asteroid Bennu, is turning out to be lighter than expected, thus allowing engineers to stuff its tanks with extra fuel to extend its mission.

The OSIRIS-REx spacecraft, being built at a Lockheed Martin facility in Denver, is coming in lighter than the lift capability of the Atlas 5 rocket, which will lift off in its “411” configuration with a four-meter payload fairing, a single-engine Centaur upper stage, and one strap-on solid rocket booster.

The proposal — described as a “heavy launch option” — would add an extra 341 pounds of fuel to the spacecraft’s fuel tank.

Planetary probes never end up lighter than planned, at least until now. During construction scientists have always found it impossible to resist adding more instruments or capabilities, and thus engineers always struggle to get the spacecraft built within its weight budget. For OSIRIS-REx to have this wonderful problem is surely astonishing.

Five years later a second attempt to put a Japanese spacecraft into Venus orbit

9:55 am

If at first: After failing to place its Akatsuki spacecraft into orbit around Venus in 2010 because of a cracked engine nozzle, Japan has announced its plans for a new attempt later this year.

The attempt will be made on December 7. If successful, the spacecraft will begin studying Venus’s climate and atmosphere only a short time after the end of Europe’s very success Venus Express mission.

The Russian spaceport construction still behind schedule

9:31 am

In a detailed update on the status of Russia’s new Vostochny spaceport, russianspaceweb reports that the construction continues to be behind schedule.

Whether they can meet the government imposed deadline of first Soyuz rocket launch by the end of 2015 seems very doubtful. More significant is this interesting quote:

In the meantime, various sensitive systems, which arrived to Vostochny for installation into unfinished facilities, were rusting inside their containers along railway sidings.

Obviously, without enough qualified personnel at the remote construction site, Spetsstroi had little choice but to focus on facilities with the highest profile for visiting Moscow officials. Moreover, the work had to be done in a great haste, increasing the chances for mistakes and leading to a low quality of construction.

Boy, does that sound like the Soviet Union all over again. It also reminds me of how most government agencies operate in the U.S.

The rockets of the world

4:36 pm

Link here.

Inspired by a book and poster from 1995, titled “Rockets of the World,” graphic artist Tyler Skrabek has provided a new and updated “clean” look for his latest work. “The ‘Rockets of the World’ poster emulates a 1960 style of drawing,” he said, “employing a consistent pallet across all rockets allowing for a distraction-free look at the size and power of the world’s greatest machines.”

A link to the poster itself can be found here. It is fascinating to compare rockets that no longer exist with those flying today.

New Pluto images from New Horizons

4:02 pm

Pluto from 126 million miles

The New Horizons science team has finally released the navigation image of Pluto and Charon that the spacecraft took on January 25.

A cropped version is on the right. The image shows Pluto and its biggest moon Charon, with both appearing somewhat elongated in shape. Why this is so is not explained by the press release, but I suspect it is because the goal of the image was not sharpness but to locate the planet for navigation purposes.

Roscomos puts the squeeze on Ukraine

8:40 am

Two more stories this week provide additional evidence that Roscosmos, the new Russian government-run space corporation that controls Russia’s entire space industry, intends to eliminate its dependence on any foreign contributions, even if that contribution comes from the former Soviet province of Ukraine.

In the first story, Roscosmos ends the commercial use of the Dnepr anti-ballistic missile, built originally in the Ukraine. In the second story Roscosmos makes it very clear that it will focus on using its Russia-made Angara rocket rather than depend on the Ukrainian Zenit, even though Zenit is what the Roscosmos-owned Sea Launch platform was designed to use and Angara is far from operational.

The main result of these decisions will be the bankrupt many Ukrainian space companies. Whether it will bring more business to Angara, however, remains to be seen. Angara has only had one orbital launch, and has hardly tested its many different configurations. At this stage it is highly unlikely that the commercial customers who have depended on Dnepr and Zenit will flock to it, especially since they now have other competitive options available in the west.

The Obama administration’s 2016 NASA budget proposal

8:32 pm

Eric Berger takes a look at the key budget items in today’s proposed budget. More details here.

As has happened in the last few years, Obama has tried to boost commercial space at the expense of SLS/Orion, one of the few positions of the Obama administration to which I heartily agree. Unfortunately, I expect Congress to also do as it has also done in the last few years, boost SLS/Orion at the expense of commercial space.

As I’ve noted before, I don’t mind that Congress trims commercial space, as giving them too much government money will make them lazy and prone to waste. What I do mind is all the money Congress spends on SLS/Orion, which is a complete waste and could be cut entirely and help reduce our debt.

The Hubble Space Telescope lives on!

8:18 pm

At a press conference at the January meeting of the American Astronomical Society scientists and engineers of the Space Telescope Science Institute that operates the Hubble Space Telescope reported that it is functioning far better than expected and is likely to continue to function until 2020 or beyond.

This is good news, since there is nothing being planned to replace Hubble. The article implies that the James Webb Space Telescope has that job, but Webb is an infrared telescope, not optical, and thus observes the universe in wavelengths not visible to the human eye.

Proton launches successfully

10:02 am

The competition heats up: Russia’s Proton successfully launched an Inmarsat commercial satellite into orbit today.

Considering the problems the Proton has had in recent years, this launch success is significant. It suggests that they are back in business.

In related news, a Russian space expert was fired from his job at a hi-tech operation outside Moscow after he publicly criticized the Putin government’s consolidation of Russia’s entire space industry into a single government-run corporation.

Vadim Lukashevich worked at the Skolkovo Innovation Center, a high-tech business park outside Moscow intended as Russia’s answer to Silicon Valley that has partnerships with Western research universities such as MIT. “As I understand it, they [fired me] for a series of interviews in which I criticize the recent decision to liquidate the Federal Space Agency and create a new state corporation called Roscosmos,” Lukashevich told The Moscow Times on Friday.

…Lukashevich, a prominent voice in the Russian space scene, told the BBC the reform would remove any industry accountability and would foster corruption — all while failing to provide Russia with a long-term direction in space.

On Wednesday, a day after the interview was published, he said someone at Skolkovo’s Space Cluster called him to say he had been fired. The caller “apologized several times, saying the decision was imposed on them from above — by a phone call from URSC in the middle of the night,” Lukashevich said

I think that Lukashevich is right, that creating a single government-run corporation will encourage corruption and in the long run will be a disaster for Russia’s space industry. We will see a rebirth of the same problems that destroyed the Soviet Union. In fact, Lukashevich’s firing is illustrative of this.

I also think that in the short term it will likely energize their space program. But only for a short period of time. After they achieve some Soviet-style stunts that appear impressive, the weight of corruption and the lack of competition will cause the industry to collapse in bankruptcy again.

Iran orbits a satellite

9:48 am

The competition, and other things, heats up: Iran state media announced today that the country had successfully launched its fourth satellite into orbit.

The reports were very lacking in information, but if true, this launch is significant in that it once again demonstrates that Iran has the capability of placing a nuclear warhead anyone on Earth. That, combined with its nuclear program that the Obama administration is allowing Iran to complete means that no one on Earth is safe from attack from this country, which only recently was ruled by a man who thought it okay to wipe whole countries he didn’t like off the map.

Air Force to open bidding on launches

9:00 pm

The competition heats up? An unnamed Air Force official has said that they intend to open up competitive bidding on as many as 10 military launches through 2017.

This might be part of the agreement between SpaceX and the Air Force that included SpaceX dropping its lawsuit and the Air Force giving a spy satellite launch that SpaceX wanted to bid on to ULA. In exchange, the Air Force will allow SpaceX to bid on a number of GPS satellite launches.

Then again, this is not an official announcement. Until it actually happens officially, I would not trust the Air Force to do what it should or promised.

New Mexico wants out of the spaceport business

9:52 am

A state law-maker in New Mexico has introduced a bill to sell off the state’s spaceport, Spaceport America.

New Mexico spent $220 million to build it and Senator Munoz now says the state has come up short. “It’s not a revenue stream and they don’t know how to get that revenue stream and that’s what needs to change,” he said. He said a private company would do a better job behind the controls and believes there is a buyer out there.

The heart of the problem here is the long delayed first flight by Virgin Galactic. Spaceport America essentially has this one customer, and Virgin Galactic has simply failed to get off the ground with its commercial flights.

Threatened water shortage on ISS

9:42 am

The crash of Antares and its Cygnus capsule in October has caused the possibility of a water shortage on ISS.

NASA had planned to certify Cygnus to carry water to the space station in early 2015; there were no plans for certifying SpaceX’s Dragon cargo ship to do the same. Orbital plans to launch its next Cygnus aboard a United Launch Alliance Atlas V rocket, but that flight is not scheduled until Nov. 19.

Meanwhile, ESA has ended flights of its ATV cargo ship, which was certified to carry water. With the ATV program over and Cygnus off-line, the space station was left with two vehicles capable of carrying water, the Russian Progress and Japanese HTV.

HTV flights are now limited to once per year; the next one is planned for August 17, just over two weeks before ISS would run out of water on Sept. 2 unless it was resupplied by other vehicles. The schedule provided very little margin for error, ASAP said.

Essentially, if either a Progress or Dragon capsule does not bring additional water to the station before August, and the HTV flight fails or is delayed by more than two weeks, the station will run out of water in early September, requiring its evacuation.
