The competition heats up: Better buy your tickets now because in a week the price for a flight on SpaceShipTwo is going up 25%.
Opportunity went into safe mode during the communications pause in April when the Sun was between Mars and the Earth.
Mission controllers for Opportunity, which landed on Mars in January 2004, first learned of the issue on Saturday (April 27). On that day, the rover got back in touch after a nearly three-week communication moratorium caused by an unfavorable planetary alignment called a Mars solar conjunction, in which Mars and Earth are on opposite sides of the sun. The Opportunity rover apparently put itself into standby on April 22 after sensing a problem during a routine camera check, mission managers said.
It sounds like this is a recoverable problem and the rover will be back in operation momentarily. Stay tuned.
The Herschel Space Telescope has closed its eye on the universe.
After four years of operation, the telescope’s supply of helium coolant has run out, leaving the infrared telescope blind to the sky.

The competition heats up: SpaceShipTwo has successfully completed its first powered flight. Some images here.
The excitement builds in Mojave for SpaceShipTwo’s first powered flight, expected on Monday..
The flight window appears to stretch from 6 pm (Pacific) Sunday to noon Tuesday.
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.
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.
This year’s Great Moonbuggy Race, the 20th, has attracted 600 international competitors.
The race itself will be held this coming weekend.

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).
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.
The countdown for the first launch of Antares today at 5 pm (Eastern) has begun.
The launch is now been delayed to 6:10 pm to allow more time for the winds to settle.
Update: due to the winds, they have decided to scrub the launch until Sunday, 5 pm (Eastern).
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.
The next Antares launch attempt has now been scheduled for Saturday, April 20, 5 pm (Eastern).
The Antares launch was scrubbed at T-12 minutes because one of the umbilical lines to the rocket separated prematurely.
Update: in a press release Orbital Sciences now says they’ve set the tentative new launch date as no earlier than April 19.
The countdown has begun for the first Antares launch. Go here for regular updates.
Right now the weather looks to be the biggest question mark, with a 50% chance it will cause the launch to be scrubbed.
The Antares rocket has been cleared for its first test launch tomorrow at 5 pm (Eastern).
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?
Putting its money where its mouth is: Russia under Vladimir Putin has announced a big financial boost from its government to its semi-private space industry.
Alan Boyle has some more information on SpaceShipTwo’s most recent test flight, and the rumors concerning the ship’s first powered flight.
A countdown dress rehearsal of the Antares rocket on Saturday was halted when a problem with a valve was discovered.
Engineers think they can replace the valve and still launch on Wednesday as scheduled.
The competition heats up: New rumors suggest that the first powered flight of SpaceShipTwo will occur April 22.
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.
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.
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?
Has Mars Reconnaissance Orbiter imaged the remains of a Soviet Mars lander from 1971?
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.
Speaking of the cracks on the first Orion capsule, here’s a story on the capsule’s state of construction.
