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

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 will replace a pump tomorrow on their spacewalk in the hope this will fix the leak in ISS’s solar panel cooling system.

The astronauts will replace a pump tomorrow on their spacewalk in the hope this will fix the leak in ISS’s solar panel cooling system.

The spacewalk has still not been approved, though it seems likely it will happen.

Update: As of this morning the spacewalk has been approved, set to begin at 8:15 am (Eastern).

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.
