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 rocket reveals a fundamental truth about America

12:29 pm

Yesterday, Orbital Sciences successfully completed the first test launch of its Antares rocket, developed, designed, and built in less than five years under a commercial contract with NASA to provide cargo to the International Space Station. The launch went like clockwork, perfectly, with no hitches at all, something that is quite remarkable for a new rocket on its first launch. Kudos to the engineers at Orbital Sciences for a job well done!

Besides demonstrating the skill of Orbital Science’s engineers, however, this successful launch illustrated in stark reality a fundamental fact about the culture of the United States that continues to allow it to stand out from the rest of the world, even as a large percentage of the present generation of Americans are doing their darndest to try to destroy that culture. Moreover, that fundamental cultural fact is basic to human nature, not just the United States, and if we recognize it, it will provide us all the right framework for what to do and not to do in trying to maintain human societies, both here on Earth as well as in the future in space.

In order to understand the true significance of Orbital Sciences’s success yesterday with Antares, however, we must first review the capabilities of the world’s launch industry. I am not going to list all the rockets capable of putting payloads into orbit, only those that are successfully competing for business in the open commercial market.

All systems are now go for the first launch of Antares at 5 pm (Eastern).

All systems are now go for the first launch of Antares at 5 pm (Eastern).

We have liftoff. All is nominal. The first stage has shut down and separated after operating perfectly. The fairings protecting the dummy payload have separated perfectly, which for Orbital is a big deal, as they have had problems with fairing shrouds on previous launches with other rockets.

The second stage engine has ignited, as planned. All is nominal, as the launch director keeps saying.

The second stage engine has shut down, as planned. Antares is in orbit. After a 90 second pause the dummy payload has separated, as planned.

A perfect launch. The United States now has two companies capable of putting cargo and payloads into orbit at reasonable prices. The competition continues to heat up.

A Russian spacewalk on ISS today.

10:06 am

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.

Because its FAA test flight permit will expire on May 23, SpaceShipTwo’s first powered flight has to occur by then and be supersonic.

The competition heats up: Because its FAA test flight permit will expire on May 23, SpaceShipTwo’s first powered flight has to occur by then and be supersonic.

What is unclear to me is how the expiration of this permit could affect future flights. Does Virgin Galactic have to get a new permit to continue test flights? What about the tourist flights that are supposed to follow?

The International Astronomical Union has issued a press release condemning the commercial efforts of private companies to issue names for exoplanets.

11:51 am

Turf war! The International Astronomical Union has issued a press release condemning the commercial efforts of private companies to issue names for exoplanets.

Recently, an organisation has invited the public to purchase both nomination proposals for exoplanets, and rights to vote for the suggested names. In return, the purchaser receives a certificate commemorating the validity and credibility of the nomination. Such certificates are misleading, as these campaigns have no bearing on the official naming process — they will not lead to an officially-recognised exoplanet name, despite the price paid or the number of votes accrued.
… [snip]
To make this possible, the IAU acts as a single arbiter of the naming process, and is advised and supported by astronomers within different fields. As an international scientific organisation, it dissociates itself entirely from the commercial practice of selling names of planets, stars or or even “real estate” on other planets or moons. These practices will not be recognised by the IAU and their alternative naming schemes cannot be adopted.

Well la-dee-da, how dare anyone else name anything ever in space!

The truth is, the IAU was originally given this function by astronomers to coordinate the naming of obscure astronomical objects, not to provide the official names for every object and feature that will ever be discovered in space. And though the IAU does tend to favor the choices of discoverers, it has in the past also ignored their wishes. (See for example my book Genesis: the Story of Apollo 8, where the IAU rejected the names chosen by the Apollo 8 astronauts, even though those astronauts were the first to actually go and see these features.)

In the end, the names of important features in space will be chosen by those who live there.

Despite a rest, Kepler’s problematic gyroscope is still having problems.

Despite a rest, Kepler’s problematic gyroscope is still having problems.

Three of the wheels are needed for Kepler’s 3.1-foot telescope to have enough sensitivity to detect the minuscule signatures of Earth-sized planets. In an exercise of caution, mission managers switched off Kepler’s reaction wheels for 10 days in January, hoping the break would redistribute lubricant inside the wheel assemblies, reducing friction and allowing the units to cool down.

But friction in wheel no. 4, which has showed friction for much of Kepler’s mission, actually increased in the month following the “wheel rest” period.

The telescope originally had four wheels. One has failed, with a second showing signs of failure. If it goes, the spacecraft will no longer be able to point with enough accuracy to do its primary mission. They might be able to use it to some observations, but its design is such that even these will be of limited value.

Vladimir Putin noted today, the anniversary of Yuri Gagarin’s spaceflight, that the new Russian spaceport being built in Vostochny will be open for use by other countries.

The competition heats up: Vladimir Putin noted today, the anniversary of Yuri Gagarin’s spaceflight, that the new Russian spaceport being built in Vostochny will be open for use by other countries.

Putin’s announcement is a bit vague, in that it is not clear whether he means the spaceport could be used by outside private companies or merely that American or European payloads will be launched from the site using Russian rockets. I suspect the latter. Regardless, Putin’s statement both to the Russian public and to the rest of the world illustrates his desire to sell the new spaceport, which in turn will bring Russia business.

Isn’t competition a wonderful thing?

Boeing this week revealed a new line of small satellites, the smallest weighing less than 9 pounds, for both military and commercial operations.

The competition heats up: Boeing this week revealed a new line of small satellites, the smallest weighing less than 9 pounds, for both military and commercial operations.

This decision tells me that my worries about Boeing’s competitiveness are unfounded. Moreover, the increasing shift to building smaller satellites will once again lower costs and therefore increase the number of customers who can afford the product. The result will be a larger aerospace industry.

Boeing is about to begin wind tunnel tests of its CST-100 manned capsule.

9:04 am

The competition heats up: Boeing is about to begin wind tunnel tests of its CST-100 manned capsule.

This is good, but there is something about the pace of development of the CST-100 that seems mighty slow to me. Last September there were indications that Boeing might shelve the project, which were countered in November by word that they were instead considering increasing their investment.

The slow pace suggests to me that management has rejected the latter. It also suggests that while they haven’t shelved the project, they are not pushing it hard, which means that eventually it will die because it will fail to compete with other more ambitious and competitive efforts.

The words of NASA’s chief: “NASA is not going to the Moon with a human as a primary project probably in my lifetime.”

The words of NASA’s chief: “NASA is not going to the Moon with a human as a primary project probably in my lifetime.”

He’s right. Instead, others will do it. And the ones who do it from the United States, privately financed for profit, will do it quickly, efficiently, and often, three things NASA has not been able to do at all since the 1960s.

NASA has indicated that the first manned launch using a commercial space carrier has slipped by a year.

9:26 am

NASA has now indicated that the first manned launch using a commercial space carrier has slipped by a year.

The reasons are as yet unclear, though it is suspected that the main cause is the decision by the Obama administration to cut the funds of this program under sequestration. As Clark Lindsey notes, however, there is no reason that some of these private companies won’t go forward and fly other passengers on their spaceships, ahead of the NASA flights. Specifically, SpaceX and its Dragon capsule should easily be ready to go well ahead of 2017, and will likely be earning enough cash from its commercial launches to pay for development even if the NASA subsidies get delayed.
