The Proton rocket is now grounded pending an investigation into today’s launch failure.

This is no surprise. What is more significant is that the crash today will likely delay all launches out of Baikonur for at least three months.

[C]ontamination will likely suspend activities at Baikonur Cosmodrome for two or three months, Ria Novosti reported, citing an unnamed source within the Russian space industry. The launch of a robotic Progress cargo ship to the International Space Station from Baikonur, currently scheduled for July 27, will probably be delayed as a result, according to this source. The next manned launch from Baikonur is Soyuz 36, which is slated to blast off on Sept. 25 to take three new crewmembers to the International Space Station.

Two Russian astronauts completed a six-hour-plus spacewalk today, preparing the station for Russia’s science module.

Two Russian astronauts completed a six-hour-plus spacewalk today, preparing the station for Russia’s science module.

This science module is many years late, delayed due to Russia’s financial problems after the fall of the Soviet Union. That the Russians are finally about to launch it is another indication, like their recent Proton rocket launch successes, that there space program might be experiencing a resurgence.

A 3D printer intended for installation on ISS in 2014 has successfully proven it can work in weightlessness.

A 3D printer intended for installation on ISS in 2014 has successfully proven it can work in weightlessness.

Three prototype versions of space manufacturing startup Made in Space’s 3D printer showed their stuff during four airplane flights that achieved brief periods of microgravity via parabolic maneuvers, company officials announced today (June 19).

Then there’s this:

“The 3D printer we’re developing for the ISS is all about enabling astronauts today to be less dependent on Earth,” Noah Paul-Gin, Made in Space’s microgravity experiment lead, said in a statement. “The version that will arrive on the ISS next year has the capability of building an estimated 30 percent of the spare parts on the station, as well as various objects such as specialty tools and experiment upgrades.” [emphasis mine]

If this claim is true, this printer will do a lot to make interplanetary space travel far more likely. It will mean that travelers far from home will be able to manufacture the spare parts they need, on demand, should something break. This will save a lot of weight, compared to carrying pre-made spare parts.

Russian concerns about a build-up of mold inside the European ATV, now docked to ISS, has caused a delay in the opening of its hatch.

Russian concerns about a build-up of mold inside the European ATV, now docked to ISS, has caused a delay in the opening of its hatch.

The Spaceflight101 portal said the delay was due to possible “mold and bacteria contamination on three cargo bags that are inside the spacecraft” and that a decision is yet to be made on whether the crew should use anti-mold kits to clean ATV-4 cargo before taking it inside the ISS.

The Russians had a lot of problems with mold in their early Salyut space stations, and understand the unpleasant consequences should mold spread into the station. Thus, I am not surprised if they are taking this issue seriously.

Great Britain’s first official astronaut has been picked for a five month mission on ISS in 2015.

Great Britain’s first official astronaut has been picked for a five month mission on ISS in 2015.

Astronaut Michael Foale was born in Britain, but he flew on Mir as an American. Britain meanwhile had banned spending any government money on space exploration in the 1960s, and hadn’t changed that policy until about two years ago. If the reaction to Canadian Chris Hatfield’s ISS mission is any guide, this mission will liven things up a bit for space exploration in the old country.

Astronauts today spotted an ammonia coolant leak in ISS’s left-side power truss.

Astronauts today spotted an ammonia coolant leak in ISS’s left-side power truss.

They are monitoring it, but have so far not made any decision about what to do about it, if anything.

This problem is a perfect illustration of why a flight to Mars is more complicated in terms of engineering than first appears. We might at this time be able to build that interplanetary spaceship (with the emphasis on the word “might”) but could its passengers maintain it millions of miles from Earth? Right now I’d say no. We need to learn how to build an easily repaired and self-sufficient spaceship. ISS is neither. It is also not a very good platform for testing this kind of engineering.

Update: The astronauts on ISS are preparing for a possible spacewalk on Saturday to deal with the problem. More details here.

The robotic demonstration of remote satellite repair on ISS resumed this week.

The robotic demonstration of remote satellite repair on ISS resumed this week.

The latest round of demos follows a breakthrough round of ground-controlled activities in January using the 70-ft.-long Canadian robot arm/Dextre combination to sever lock wires and remove a mock fuel cap to flow 1.7 liters of ethanol fuel into the RMM.

The new tests will see if the robot arm can do even finer and more difficult tasks, such as unscrewing and storing a small screw.

The European Space Agency is investigating the possibility that the Progress docking to ISS on April 26 might have damaged equipment needed by their ATV cargo ship.

The European Space Agency is investigating the possibility that the Progress docking to ISS on April 26 might have damaged equipment needed by their ATV cargo ship.

The damage, caused by the undeployed Progress antenna, appears to have involved a navigational aid needed for ATV-4 … the Laser Radar Reflector (LRR) target. The LRR is needed for the automatic docking of the European ATV during the last part of the rendezvous operations. If the damage is confirmed, the device, recently replaced during an EVA by the Russian crew due to contamination of the optical section, will need to be replaced again. In this event, the European cargo ship could potentially be delayed for several months. ATV-4, named Albert Einstein, has been already delayed from April to June because of a glitch in an avionics box.

It appears the Progress freighter has successfully docked with ISS.

It appears the Progress freighter has successfully docked with ISS.

The story is not entirely clear on whether this was a successful hard dock, or only a soft dock. However, I’ve done a search on the web and it sounds like the docking was good. This story says the astronauts on ISS will conducting leak tests (a normal procedure) and then begin unloading, which suggests that all is well.

A hard docking is confirmed.

A new report from Russia suggests that the undeployed antenna on the Progess freighter will interfere with ISS’s docking port and prevent a docking.

A new report from Russia suggests that the undeployed antenna on the Progess freighter will interfere with ISS’s docking port and prevent a docking.

It appears that the antenna would allow a soft docking but prevent the hard docking necessary to allow for the opening of the hatch. Something similar to this had happened on the Russian Mir station in the 1987. Two astronauts did a space walk to clear the hatch of a piece of debris. Now the Russians are suggesting again that if a hard dock becomes impossible a spacewalk be performed to get the antenna out of the way.

An antenna used to orient a Progress freighter during docking, launched today to ISS, has failed to deploy.

An antenna used to orient a Progress freighter during docking, launched today to ISS, has failed to deploy.

Though astronauts can manually dock the spacecraft, they still need proper radar data to gauge its location, spin, orientation, speed, and distance. If the remaining four antennas cannot provide all this information, it will be very dangerous to try a docking.

A problem like this has not happened on a Progress freighter in literally decades. When I consider the spate of other recent failures experienced by the Russian space industry, I can’t help wondering whether they have developed an overall quality control problem.

Update: Russian mission control said today that even if they cannot solve the deployment failure and get the antenna working it will not prevent a docking with ISS on Friday.

I tend to believe them. With four other antennas plus additional radar equipment on ISS it does seems reasonable that there is sufficient redundancy to allow the docking to proceed. Also, considering the Russians past problems with collisions on Mir, I would expect them to be very careful about proceeding if they had any doubts.

A Russian spacewalk on ISS today.

A Russian spacewalk on ISS today.

What is especially interesting about this spacewalk is its participants, Pavel Vinogradov and Roman Romanenko. Vinogradov at 59 years old is the oldest person to do a spacewalk. It is his seventh EVA. Roman Romanenko meanwhile is following in the footsteps of his father, Yuri Romanenko, who spent three months in space in the late 1970s on Salyut 6 followed by a ten month mission on Mir in 1987. As far as I can remember, this makes Romanenko the first second-generation astronaut in history.

Update: a reader has noted that Richard Garriott was the first second generation astronaut, beating Romanenko by one year. See the comments.
