Some details on the SpaceX’s attempt to land its Falcon 9 first stage

8:38 am

This SpaceX press release gives some good info on the difficulty they face getting the first stage on Tuesday’s Dragon launch to land successfully on its floating sea platform:

To complicate matters further, the landing site is limited in size and not entirely stationary. The autonomous spaceport drone ship is 300 by 100 feet, with wings that extend its width to 170 feet. While that may sound huge at first, to a Falcon 9 first stage coming from space, it seems very small. The legspan of the Falcon 9 first stage is about 70 feet and while the ship is equipped with powerful thrusters to help it stay in place, it is not actually anchored, so finding the bullseye becomes particularly tricky. During previous attempts, we could only expect a landing accuracy of within 10km. For this attempt, we’re targeting a landing accuracy of within 10 meters.

They are going to try however, and they will be filming their attempt all the way. Stay tuned for some very interesting footage.

A Russia/Brazil partnership for Sea Launch?

9:30 am

The competition heats up: Russia is negotiating a partnership with Brazil to operate Sea Launch.

The Sea Launch rocket is built by Ukraine, which presently has hostile relations with Russia, to say the least. The platform, built with Boeing money, is presently docked on the the U.S. west coast, which is also not what Russia wants. Moving it to Brazil and adapting it for use with a Brazilian rocket solves both problems, though the usability of Brazil’s rocket is at this moment quite questionable.

India’s Mangalyaan Mars probe working fine

9:22 am

After three months in orbit around Mars, India’s Mangalyaan spacecraft continues to function as designed, and is expected to operate beyond its planned six month mission.

In the last three months, Mangalyaan has captured nearly 300 pictures. On an average the spacecraft takes four pictures in three days. Besides capturing the images of dust storm activities, it has also taken images of comet Siding Spring.

Because of Mangalyaan’s orbit and the wide-angle nature of its camera the pictures are generally global. This output also is not spectacular compared to other probes. Nonetheless, this is an achievement for which India should be proud.

Nicaragua and China break ground on new canal

2:47 pm

In a largely symbolic act, Nicaragua broke ground on Monday on the Chinese-backed construction of a new canal connecting the Atlantic and Pacific oceans.

The project is being pushed by Nicaraguan President (and former Marxist guerrilla leader) Daniel Ortega and financed by Wang Jing, “a little-known Chinese telecom mogul well connected to China’s political elite.” And as much as normally support any ambitious effort to create business opportunities for people in poor countries, this quote from the article raised some red flags about the project I hadn’t thought of previously:

The proposed canal is set to intersect Lake Nicaragua, known locally as Lake Cocibolca, sending cargo ships and tankers straight through the largest source of freshwater in Central America. Further, the canal is expected to displace tens of thousands of mostly rural and indigenous landholders and would likely devastate over 400,000 acres of rainforests and wetlands, which scientists say are critical to local and regional biodiversity conservation efforts.

I am usually very skeptical of environmental protests since their motives are almost always to promote socialism or communism and not to protect the environment. Here however the protests are against a project being promoted by a Marxist ruler and the communist Chinese. Moreover, it does seem a reasonable question to worry about the possible introduction of ocean saltwater into “the largest source of freshwater in Central America.”

Angara A5 rocket launches successfully

8:55 am

The competition heats up: Russia successfully completed the first test launch of the heavy-lift version of its Angara rocket today.

More background here.

At this moment the dummy payload is in a preliminary orbit and requires additional engine burns by the Briz-M upper stage to reach its planned geosynchronous orbit. Briz-M however is well tested and has been in use for years already on the Proton rocket. Therefore, for Angara this flight has now been a complete success, even if the Briz-M stage fails.

Successful Falcon 9 static fire

9:25 pm

After unspecified issues on a static fire test last week caused the postponement of the Falcon 9/Dragon launch until January 6, SpaceX followed up with a successful full static fire test of the rocket on Friday.

SpaceX fueled up a Falcon 9 rocket, ran through a mock countdown and fired the booster’s nine Merlin main engines Friday in a successful preflight static fire test officials hope will clear the way for liftoff Jan. 6 on a space station resupply mission. The exercise occurred at approximately 2:55 p.m. EST (1955 GMT) Friday while the Falcon 9 rocket and a Dragon supply ship were kept grounded at Cape Canaveral’s Complex 40 launch pad.

Friday’s Falcon 9 launch delayed

6:31 pm

Because of a scrubbed static fire test on Tuesday, it is now likely that Friday’s Falcon 9/Dragon launch will be delayed until January.

Attempts during the four hour test window on Tuesday did not result in a successfully conducted Static Fire. Several requests for further information, sent to SpaceX during and after the test window, resulted in the company saying they had no information to provide. SpaceX normally provide confirmation after a successful conclusion to the test.

Source information noted at least one full countdown towards the firing was attempted, which was classed as aborted at the very end of the count. At least one NASA-based outlet claimed the Static Fire had taken place, potentially pointing to ignition of the Merlin 1D engines, before an abort – due to an issue – was likely called. No confirmed information on the issue has been forthcoming from SpaceX. However, the company has promised to provide more information to this site when “they have something to share.”

It was, however, understood that the next Static Fire attempt is likely to take place no sooner than Thursday. That too appears to have been cancelled following review.

If tomorrow’s static fire test has been canceled then Friday’s launch will definitely be canceled as well. None of this has been confirmed yet, however, so it is possible that all is well and the launch will go forward as planned.

Update: The launch delay has now been confirmed. A new launch has not yet been announced however.

Countdown begins for the suborbital test flight of India’s new rocket

9:52 am

Link here. The launch is scheduled for 11 pm Eastern tonight.

Thursday’s test launch will check the performance of the GSLV Mk. 3’s first stage and strap-on boosters, which will carry the rocket out of the atmosphere beyond the boundary of space. The launcher’s cryogenic upper stage, which will be active and fueled by liquid hydrogen on future missions, will be dormant on Thursday’s flight.

…After the rocket’s propulsion shuts down, a gumdrop-shaped capsule will separate from the GSLV Mk. 3’s dummy upper segment about five-and-a-half minutes after liftoff, according to the Times of India, another English-language paper in India. The capsule weighs about 8,000 pounds — about 3.6 metric tons. Indian engineers from Hindustan Aeronautics Ltd. fabricated the car-sized module, and ISRO added sensors, strain gauges, a guidance and control system and a heat shield for the suborbital flight, which is called the Crew Module Atmospheric Re-entry Experiment, or CARE.

The seas of Titan

9:27 am

Thar’s black gold up thar! Data from Cassini has confirmed the presence of ocean waves on Titan’s seas, while also providing suggesting that they are made mostly of liquid methane, not ethane as had been predicted.

The maximum depth of Kraken Mare appears to be 160 meters, and Ligeia Mare could be as much as 200 meters deep, reported Marco Mastrogiuseppe of Sapienza University of Rome. The fact that the radar signals could bounce off the sea bottom suggests that the seas were more transparent than expected and thus must contain mostly methane, not ethane. Hayes says his best estimate is about 90% methane. Essam Marouf, a planetary scientist at San José State University in California, reported on the first results from a separate radar experiment that sent radar reflections to Earth instead of back to the spacecraft. Those tests provide independent evidence that the seas are dominated by methane, Marouf says, and it implies that the lakes are kept filled by precipitating methane.

As the article also notes, this methane is “55 times Earth’s oil reserves.”

The reasons behind Russia’s proposed new space station

9:12 am

Link here.

At the heart of the latest plan is the botched construction of the Multi-purpose Laboratory Module, MLM, the Russia’s next big piece of the International Space Station, ISS. After many years of delays, the price tag for the MLM project ballooned to one billion rubles, however the all-but-completed module had to be grounded until at least 2017 due to severe quality control problems during its manufacturing at GKNPTs Khrunichev in Moscow. Repairs of the module were estimated at another billion rubles and GKNPTs Khrunichev was expected to cover this cost from its own reserves. However, the nearly bankrupt company came back with an announcement that it already owed around a billion Euro and would not be able to pay for the future work. Even if repaired and successfully launched, the MLM module, which would have taken more than two decades to build, could arrive at the ISS on the eve of its retirement.

As an alternative, Russian space officials came up with a new scheme to build a whole new station around the MLM, instead of launching it to the ISS. The project with an estimated price tag from four to five billion rubles would cover a five-year delay in the construction of the ISS. The new Russian station would also utilize all future Russian modules, which were expected to follow MLM to the ISS, such as the Node Module, UM; the Science and Power Module, NEM; an Inflatable Habitat, and the OKA-T laboratory.

There’s more. Read it all.

The Falcon 9 first stage landing barge about to set sail

7:08 pm

The competition heats up: The barge that SpaceX has modified to provide an ocean platform for the first stage of its Falcon 9 rocket to land on is ready to leave port for Friday’s Dragon launch.

I think this Friday’s launch should be far more interesting and exciting that the Orion test flight a little over a week ago. Unlike the Orion flight, SpaceX will be attempting something that has never been done before. And should they succeed, they will rock the aerospace industry as much as Sputnik did in 1957.

Update: SpaceX put out a press release late on Tuesday detailing precisely what they hope to do, with videos from previous atttempts.

Orbital Sciences picks another Russian engine for Antares

7:02 pm

The heat of competition: In its effort to replace the old Cold War Soviet-era refurbished Russian engines for the first stage of its Antares rocket, Orbital Sciences today announced that it will instead buy a different modern-built Russian engine.

Designated the RD-181, the new engine will be used on Antares in shipsets of two to accommodate as closely as possible the two-engine configuration built around the AJ-26 engines supplied by Aerojet Rocketdyne, Orbital Sciences managers said Dec. 16. A descendant of the RD-171 that powers the Ukrainian-built Zenit launch vehicle, the RD-181 will be manufactured in the same Khimki factory that builds the RD-180 used on the United Launch Alliance Atlas V. It closely resembles the RD-191 on Russia’s new Angara launcher and the RD-151 that powers South Korea’s Naro-1 launch vehicle.

It appears that this is the only engine presently available that can do the job. In the long run however it puts Antares and Orbital Sciences at a competitive disadvantage. Even though the sanctions against using Russian engines, passed by Congress, only apply to military launches, Orbital’s continuing reliance on Russian engines will limit their customer base.

Boeing to bid CST-100 for ISS cargo contract

6:47 pm

The competition heats up: Boeing has submitted a bid for the next round of ISS cargo missions, proposing to use its CST-100 manned craft as an unmanned freighter.

The cargo version of Boeing’s CST-100 spacecraft will be based on the crewed version the company is developing for NASA, said John Mulholland, Boeing commercial crew program manager. Boeing will remove spacecraft components not needed for crew missions, like its launch abort system and environmental controls, to free up room in the spacecraft for cargo. The cargo version of CST-100 would, like the crewed version, launch on a United Launch Alliance Atlas 5 rocket. The cargo version will also be able to return cargo to Earth, landing in the western U.S. like the crewed version.

This makes sense to me.

NASA builds a $349 million test stand it knows it will never need

11:58 pm

SLS marches on! Though Obama cancelled the Constellation rocket program in 2010, NASA continued to build a $349 million engine test stand for that rocket, finishing the tower in June 2014.

The test stand was also significantly over budget. It now sits useless, since the SLS rocket will use a different untested engine in its upper stage during its first manned flight.

It is every important to underline the chronology here. The rocket was cancelled in 2010. Construction on the test stand continued however for four more years, partly because of decisions by NASA management and partly because of mandates forced on them by Congress.

Stories like this illustrate why I think the political clout of SLS is weak. The program is too expensive, is riddled with waste, and it can’t accomplish anything anyway, making it a perfect target for both muckraking journalists and elected officials who want to make a name for themselves saving the taxpayer’s money. And both have a perfect inexpensive and successful alternative to turn to: private space.

Simon & Garfunkel – American Tune

6:01 pm

An evening pause: Performed live in New York, 1981.

I’ve posted a different Paul Simon performance of this song previously, but considering what SpaceX is about to try to do with its first stage, I think it appropriate to post it again. As Simon wrote,

We came on a ship they called the Mayflower
We came on a ship that sailed the moon
We came in the age’s most uncertain hour
And sing an American tune.

A new Russian heavy lift rocket amid Russian budget woes

10:18 am

The competition heats up: Even as Russia today successfully placed a commercial satellite in orbit on the 400th successful Proton rocket launch, Russian sources indicate that — despite budget woes fueled by the drop in oil prices — Russia is moving ahead with the design and construction of a heavy-lift rocket capable of competing with NASA’s Space Launch System (SLS).

From the last link above:

By 2013, Roskosmos drafted a very preliminary roadmap toward the development of heavy and super-heavy launch vehicles. Not surprisingly, it matched closely the strategy that NASA had followed since 2011 within the Space Launch System, SLS, project.

…As the American SLS project, Russian super-heavy launcher plans envisioned building a rocket with a payload of 80-85 tons in the first phase of the program. A pair of such rockets would be enough to mount a lunar expedition. In the second phase of development, the rocket would be upgraded to carry unprecedented 130-180 tons of payload in order to support, permanent lunar bases, missions to asteroids and expeditions to Mars.

As much as I remain a skeptic of SLS, it has apparently struck so much competitive fear in the Russian leadership that they are now willing to try to copy it. Much like the 1980s, when the Soviet rulers bankrupted their nation trying to duplicate American projects like the Strategic Defense Initiative and the Space Shuttle, Putin is now repeating that error all over again. His country has experienced almost a quarter-century of strong economic growth since the fall of communism because, during that time, they focused on capitalism, private enterprise, freedom, and a bottom-up economic structure. Now, they are beginning to abandon that approach and return to the top-down, centralized system of government planning.

As it did in previous century, it will bankrupt them again in this century. Though the Russian government is denying the reports that they are going to trim their space budget, their government’s budget is going to suffer from the drop in the price of oil. Something will have to give.

Update: This review of a book about modern Russia is definitely pertinent: The Land of Magical Thinking: Inside Putin’s Russia

Airbus attacked by French lawmaker for talking to SpaceX

8:56 am

The competition heats up: A French lawmaker lashed out at Airbus for daring to consider SpaceX as a possible launch option for a European communications satellite.

The senator, Alain Gournac, who is a veteran member of the French Parliamentary Space Group, said he had written French Economy and Industry Minister Emmanuel Macron to protest Airbus’ negotiations with Hawthorne, California-based Space Exploration Technologies Corp. for a late 2016 launch instead of contracting for a launch on a European Ariane 5 rocket. “The negotiations are all the more unacceptable given that, at the insistence of France, Europe has decided to adopt a policy of ‘European preference’ for its government launches,” Gournac said. “This is called playing against your team, and it smacks of a provocation. It’s an incredible situation that might lead customers to think we no longer have faith in Ariane 5 — and tomorrow, Ariane 6.”

Heh. SpaceX really is shaking up the launch industry, ain’t it?

No more Russian engines for ULA

10:34 am

The heat of competition: The new budget, passed by the House yesterday, includes a provision both banning ULA from buying any more Russian engines for its Atlas 5 rockets as well as providing $220 million to help develop a new engine.

Combined with the likely approval of SpaceX to also launch military payloads, ULA is under significant pressure to get those Russian engines replaces as quickly as possible.
