It appears that NASA is planning to go ahead with at least one spacewalk to replace ISS’s faulty coolant system pump.

It appears that NASA is planning to go ahead with at least one spacewalk to replace ISS’s faulty coolant system pump.

After attempts from the inside to restart the malfunctioning cooling loop on the International Space Station failed last night, NASA mission managers have decided a spacewalk will be required to fix the problem, a source privy to NASA operations told TV20 News. NASA mission managers have scheduled the first spacewalk for Dec. 19th, according to the source, with two other spacewalks, also known as EVAs, likely to follow a few days after.

This story is not yet confirmed, but this AP article suggests it might be true.

The coolant systems failure on ISS might delay next week’s Cygnus cargo mission.

The coolant systems failure on ISS might delay next week’s Cygnus cargo mission.

[T]he reduced cooling capability means there’s less of a safety margin on the station. Todd said mission managers don’t want to risk having the Cygnus come in for a hookup under such conditions. “While we’re sitting at one loop, we’re somewhat vulnerable,” he said.

The logic here escapes me. It suggests they will stop all cargo missions to ISS until the coolant problem is solved. However, what if they can’t solve it without a spacewalk? To do that spacewalk they have to deliver an upgraded spacesuit to the station to replace the suit that had water leak problems in July, and that delivery is not scheduled until late February when the next Dragon cargo launch is scheduled.

Maybe they are considering putting that replacement suit on the Cygnus capsule so it can arrive quickly. If so, that would justify delaying the Cygnus launch for a few days.

More details about the situation here.

If a US spacewalk on ISS is necessary to repair its cooling system, the spare parts are there, but the spacesuits are not.

8:35 am

If a US spacewalk on ISS is necessary to repair its cooling system, the spare parts are there, but the spacesuits are not.

Prior to retiring the shuttle NASA, aware that cargo supply would be limited once the shuttle was gone, shipped up to the station as many spare parts as possible. Thus, there are three spare pump modules on ISS that could be installed during a spacewalk to replace the module that has the valve problem.

However, because of the water leak problem that occurred in one American spacesuit during a July spacewalk, NASA has halted all American spacewalks until replacement suits can be shipped up to the station.

Since then, NASA has been conducting extensive investigations into the water leak issue, with… “the crew performed a series of tests on EMU 3011 [the faulty spacesuit] as part of an ongoing effort for returning the suit back to service. The tests included water leak checks, communication checks, and suit pressure leak checks. EMU 3011 passed all tests.”

However, NASA had been planning to wait to return another EMU, serial number 3015, to Earth aboard a SpaceX Dragon vehicle and deliver a new EMU in its place before clearing EVAs to resume. However the next Dragon vehicle is not scheduled to arrive at the ISS until at least late February next year.

The Russians might be able to do this spacewalk, but they are going to demand payment for the work. And they won’t come cheap, considering the circumstances.

India’s Mangalyaan Mars probe successfully completed its first midcourse correction maneuver today.

India’s Mangalyaan Mars probe successfully completed its first midcourse correction maneuver today.

As with the images the probe took of Earth, the success of this maneuver demonstrates the ability of the probe’s engineers to control, operate, and precisely point the spacecraft’s engine. It also proves that engine works as designed.

Here’s an interesting cultural tidbit: Of the 200,000 people who have applied to Mars One (see my previous post below) to go on its proposed one-way mission to Mars, India has the second most applicants after the U.S.

Mars One applicants come from over 140 countries; the largest numbers are from the US (24 per cent), India (10 per cent), China (6 per cent), Brazil (5 per cent), UK, Canada, Russia and Mexico (4 per cent), Philippines, Spain, Colombia and Argentina (2 per cent), and Australia, France, Turkey, Chile, Ukraine, Peru, Germany, Italy and Poland (1 per cent).

A private unmanned mission to Mars by 2018?

A private unmanned mission to Mars by 2018?

Dutch entrepreneur Bas Lansdorp, Mars One founder and CEO, told reporters the foundation has signed contracts with two major aerospace firms, Lockheed Martin and Surrey Satellite Technology, to develop mission concept studies, a first step toward eventual construction and launch.

The lander will be based on the design of the 2007 Phoenix Mars lander that Lockheed Martin developed for NASA. The communications satellite — the first such “geostationary” comsat in orbit around the red planet — will incorporate technologies developed by Surrey and used in a variety of operational spacecraft.

Mission concept studies are of course essential before you begin construction, but they are also a far cry from actual construction. I’ve seen literally hundreds of similar concept studies about someone’s big space plans with no subsequent follow up. Thus, I will only begin to take Mars One serious when they actually start cutting metal.

International Launch Services ((ILS) has successfully launched its Russian Proton rocket to put another commercial communications satellite into orbit.

Tbe competition heats up: International Launch Services ((ILS) has successfully launched its Russian Proton rocket to put another commercial communications satellite into orbit.

This launch solidifies the recovery of the Proton rocket since the disastrous July launch. With the Russian government forcing a consolidation of all Russian aerospace companies into one government owned cooperation, however, it is unclear what will happen to ILS and Khrunichev (the Russian company that makes the Proton).

A map of Opportunity’s journey on Mars as it approaches its tenth anniversary since landing on January 25, 2004.

A map of Opportunity’s journey on Mars as it approaches its tenth anniversary since landing on January 25, 2004.

The map gives some nice perspective of just how far the rover has traveled in the past decade, as well as the increasing scale of the geological features it has observed. Opportunity began inside tiny Eagle Crater, moved on to larger Endurance Crater, then to the even bigger Victoria Crater, and now to the truly massive Endeavour Crator, 14 miles in diameter.

Let the space price war begin.

9:20 am

Let the space price war begin.

Two money quotes:

This latest launch is bad news for Russia, Europe, Boeing, and Lockheed Martin. SES paid $55 million to SpaceX for the launch; rivals typically charge $100 million to $200 million. SpaceX has a backlog of about $4 billion worth of launches, many for commercial customers that it can now begin to serve.

and this:

We’ll really get a sense of SpaceX’s abilities over the next year. The company plans to launch rockets at a much more ferocious clip, to refine their reusability and to prepare for sending humans to the International Space Station. You can also expect to see SpaceX tormented by politicians with ties to existing launch contractors and military suppliers. May we live in interesting times.

How India’s cryogenic rocket engine program was hampered and delayed, by the United States.

How India’s cryogenic rocket engine program was hampered and delayed, by the United States.

The article is fascinating, and rings very true until the last section. George Bush Sr. was an old CIA guy who distrusted the Soviets enough to want to prevent them from having any dealings with India, and Bill Clinton was very hostile to India during his entire administration. It is very easy to believe both presidents worked to stymie India’s efforts to work with the Russians.

SpaceX Falcon 9 launch

3:38 pm

All is go for today’s Falcon 9 launch with less than four minutes left in the countdown. You can watch it live here.

We have liftoff. The real moment of truth on this launch will be once the rocket is in orbit. Can its upper stage relight to lift the SES satellite to geosynchronous orbit?

The rocket is now in orbit. The final engine burn and payload separation will occur within the hour.

The second stage engine burn has been successful. We now await payload separation.

The payload has separated successfully and has been delivered to its planned orbit.

With this successful launch SpaceX is poised to dominate the launch industry. Every other launch company has got to cut its prices in half, or more, in order to compete.

In a 376-5 bi-partisan vote, the House has approved a one year extension to the liability exemption of the 2004 Space Amendments Act.

In a 376-5 bi-partisan vote, the House has approved a one year extension to the liability exemption of the 2004 Space Amendments Act.

Though this is helpful, it still leaves intact the regulations imposed by that 2004 law, all of which make difficult the future of space tourism. That this extension was passed in conjunction with an effort by Congress to overhaul the law is encouraging.

A Connecticut museum, having switched its focus from art to science, has chosen to sell its most valuable statue to finance its own cubesat.

Art vs Engineering: A Connecticut museum, having switched its focus from art to science, has chosen to sell its most valuable statue to finance its own cubesat.

The Discovery Museum and Planetarium in Bridgeport is making a calculated trade-off as it launches a significant upgrade to its science education program for schoolchildren. The 55-year-old museum is auctioning a massive bronze statue Friday to raise money to outfit and program a satellite the size of a milk carton attached to a NASA rocket beaming back data on space dust. …

The statue [is] of a man handing a torch to another man reaching down while on a horse symbolizes the passing of the knowledge of civilization from one generation to the next. …

The satellite will be programmed to capture small space debris analyzed by students in high-school and younger at the museum’s Challenger Learning Center. “We’re building a mission control at the museum,” said David Mestre, director of space science education at the museum. “We’re developing software for a kid to run a space program.” [emphasis mine]

That last quote clinches the deal for me. The statue is impressive, but it merely expresses the idea. Having children operate their own space satellite puts the idea into action.

India has delayed the first test launch of its Geosynchronous Satellite Launch Vehicle (GSLV) from mid-December until the first week in 2014.

India has delayed the first test launch of its Geosynchronous Satellite Launch Vehicle (GSLV) from mid-December until the first week in 2014.

This delay appears to be simple prudence. They have no specific deadline for launch, and by giving themselves a few extra weeks they can make sure they have things right. I also have two additional comments.

First, I wish they would give this rocket a decent name. GSLV is not only hard to remember, it is ugly. A better name would help their marketing enormously.

Second, read the comments at the link. They are all from Indians, and the majority of them are very enthused. It will give you a sense of that country’s passion for technology and science.

Exciting Times in Space

7:00 am

Tonight I will make another of my many appearances on the Space Show with David Livingston. What makes this particular appearance special is that it will be the tenth anniversary of my first appearance on the show. Ten years ago tonight, on December 3, 2003, I appeared with David to discuss both the history of space exploration as well as its future — as we saw it then. (If you want to listen to that first appearance simply go to this link.)

For the first half of the show our discussion mostly focused on history, the 1960s space race, and my book, Genesis: the Story of Apollo 8 (now available as an ebook).

During the second half, our conversation began to range far and wide, speculating about the future of manned space exploration and what would be the best ways to jump start the American effort. Though I did not get everything right, what I said then has turned out to have been a remarkably accurate prediction of what has happened since.

To set the context, this appearance occurred only six weeks before George Bush’s January 14, 2004 speech where he announced his vision for space exploration. At the time we did not know what Bush would say, or even if he would propose anything, though there had been a lot of rumors that Bush was about to make a Kennedy-like speech proposing another Kennedy-like NASA mission to explore the solar system. David Livingston asked me what I thought would happen.
