False ammonia leak alarm causes evacuation of US portion of ISS

A false alarm on ISS early this morning, signaling the leak of ammonia coolant, forced the evacuation of the American portion of ISS.

American engineers are assessing the cause of the alarm, though they seem pretty confident now said that no leak of any ammonia took place and the problem was likely caused by a faulty sensor.

Update: The crew has now returned to ISS.

A close look at Russia’s next generation space station modules

The competiton heats up: Anthony Zak’s a detailed report of the design and development of the next generation space station modules Russia intends to dock at ISS has this interesting tidbit:

In addition to expanding the ISS, Russian developers viewed the NEM module as the basis for future Russian efforts to send humans beyond the Earth orbit. Thanks to its multi-function design, life support and power-supply capability, one or a whole cluster of such vehicles could provide habitation quarters and laboratories for a station at the so-called Lagrange points, which were considered as a staging ground for the exploration of the Moon, asteroids and Mars.

In case of an international agreement on the construction of a manned outpost in the Lagrange point, the NEM-based laboratory could constitute the Russian contribution into the effort. The NEM-based outpost could be serviced and staffed by the crews of US-European Orion spacecraft and by Russia’s next-generation spacecraft, PTK NP. Simularly, the NEM module, possibly in combination with other hardware, could serve as an outpost in the orbit around the Moon. Also in 2014, plans were hatched to make the NEM-based laboratory a part of the post-ISS Russian space station, VShOS, in the high-inclination orbit.

The Russians have always understood that a space station is nothing more than a prototype of an interplanetary spaceship. They are therefore simply carrying through with the same engineering research they did on their earlier Salyut and Mir stations, developing a vessel that can keep humans alive on long trips to other planets.

This approach makes a lot more sense that NASA’s SLS/Orion project, which does not give us what we need to make long interplanetary voyages, and costs a lot more.

A Russia/Brazil partnership for Sea Launch?

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.

Angara A5 rocket launches successfully

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.

The reasons behind Russia’s proposed new space station

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.

Orbital Sciences picks another Russian engine for Antares

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 Russiaโ€™s new Angara launcher and the RD-151 that powers South Koreaโ€™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.

A new Russian heavy lift rocket amid Russian budget woes

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
