New Horizons to begin observations of Pluto

4:23 pm

In preparing for its July 14 fly-by of Pluto, New Horizons will take its first images of the planet on January 25.

Snapped by New Horizons’ telescopic Long-Range Reconnaissance Imager, known as LORRI, those pictures will give mission scientists a continually improving look at the dynamics of those moons. And they’ll play a critical role in navigating the spacecraft as it covers the remaining 135 million miles (220 million kilometers) to Pluto. “We’ve completed the longest journey any craft has flown from Earth to reach its primary target, and we are ready to begin exploring!” said Alan Stern, New Horizons principal investigator from Southwest Research Institute in Boulder, Colorado.

Over the next few months, LORRI will take hundreds of pictures of Pluto against star fields to refine the team’s estimates of New Horizons’ distance to Pluto. Though the Pluto system will resemble little more than bright dots in the camera’s view until May, mission navigators will use those data to design course-correction maneuvers that aim the spacecraft toward its flyby target point this summer. The first such maneuver could occur as early as March.

SpaceX to open satellite-building operation in Washington state

8:28 am

The competition heats up: Within three years SpaceX hopes to establish a new satellite operation in Seattle, Washington, employing 1,000 people and focused on the design of smaller, cheaper satellites.

The key quote from the article perhaps is this: “Musk said the office would focus on developing satellites but could also be a base for rocket-design talent uninterested in moving to SpaceX’s base in the Los Angeles area.” To put it another way, California’s socialist and highly restrictive state government has forced Musk to consider an alternative location for the expansion of his company.

His effort should also strike fear into the established satellite makers, who have done relatively little innovative design changes in the past four decades. As SpaceX has done with the launch industry, I expect SpaceX will do with the satellite industry: force them to lower costs while developing new technologies.

Test flight of Europe’s first prototype space plane has been rescheduled

9:55 am

The competition heats up: Preparations have resumed for a February 11 test flight of a European prototype space plane, initially scheduled for November but cancelled at the last minute because managers suddenly discovered its launch path was going to go over land.

The launch trajectory of the IXV space plane on a suborbital trajectory will differ from the Vega rocket’s previous flights, which flew north from the space center with satellites heading for high-inclination polar orbits. The launch of IXV will head east from Vega’s launch pad, and the geometry of the French Guiana coastline means it will fly over land in the first phase of the launch sequence.

Officials said they slightly adjusted the launch track to alleviate the the safety concern.

The four-stage Vega rocket was stacked on the launch pad at the Guiana Space Center, and the IXV spacecraft was about to be fueled with hydrazine maneuvering propellant when officials announced the delay in October. A ship tasked with retrieving the space plane after splashdown in the Pacific Ocean had already left port in Italy when news of the launch delay was released.

I remain suspicious about the cause of the delay in November. How could they not have known about the launch trajectory until the last second? Instead, I suspect it occurred because of politics higher up in ESA related to Italian, German, and French tensions over the future of Arianespace. The Italians are the lead on this space plane project, to the apparent chagrin of the French, who mostly run the launch facility in French Guiana. Moreover, it appears the Italians have generally sided with the Germans against the French in the Ariane 6 design negotiations. I wonder if the delay was instigated by higher management in an effort to influence those negotiations.

High Russia space official shoots down idea of new Russian space station

9:35 am

Sergei Savelyev, deputy director of Russian space agency Roscosmos, dismissed the idea that Russia might leave the ISS partnership to build its own independent space station.

“Theoretically it is possible to create a new Russian space station, but neither the current nor future drafts of the federal space program [through 2025] touch on this subject, and any [hypothetical] implementation could be tied in with the continued operation of the ISS,” [he said]…

Savelyev added that he anticipates Russia will continue to use the ISS beyond 2020, but that its focus will shift toward cooperating with China on Beijing’s own space stations — a small station is already in orbit, and a second larger one is set to be operational around 2020 — and aboard the Russian segment of the ISS.

I think the Russians know that it would be foolish to abandon their partnership on ISS, at least not for a few more years. For at least another decade it is going to be the best thing they’ve got in space.

Falcon Heavy launch still set for 2015

9:40 pm

The competition heats up: According to SpaceX officials, the first test flight of their Falcon Heavy rocket is still on schedule to occur sometime in the third quarter of 2015.

We should all take this schedule with a grain of salt. Back in 2013 SpaceX had scheduled the first Falcon Heavy launch for the second half of 2014. Then in April 2014 they said it would occur early in 2015. Now they say the third quarter of 2015. I would not be surprised if there are further delays beyond this.

Nonetheless, I have no doubt that they will launch this rocket. SpaceX has consistently delivered on its promises, which is one reason it has grabbed so much of the launch market in such a short time.

Dream Chaser lives on!

8:55 am

The competition heats up: Sierra Nevada reveals that it intends to bid its Dream Chaser mini-shuttle as an ISS cargo vessel in NASA’s next round of cargo contracts.

The company also says that it is continuing development of the shuttle right now, despite the present lack of a contract. If this is true, I would expect them to do, as promised, the additional glide tests they had planned, using their engineering test vehicle. If not, then the claim of further development is merely talk, a lobbying effort to improve their chances of winning the next contract.

Not that I blame them. I just think they would do themselves a lot more good doing an actual glide test.

Photos of SpaceX’s floating landing barge

9:41 am

The landing barge on which the first stage of the Falcon 9 attempted to land has returned to port.

Photos of the barge show signs of blast and burn damage to cargo containers and possible wreckage from the rocket covered by tarps on the platform’s deck. The rest of the vessel appeared undamaged.

These photos do not show as much wreckage as I would have expected, though my expectations here aren’t based on much knowledge. I would have thought that the first stage remains would have been more substantial.

Cruz and Rubio to chair important space and science subcommittees

3:40 pm

We are about to find out how conservative and pro-private enterprise senators Ted Cruz (R-Texas) and Marco Rubio (R-Florida) really are. Both have been assigned as chairmen of important subcommittees managing NASA and NOAA.

Cruz will chair the subcommittee on Space, Science, and Competitiveness, which handles NASA, while Rubio will chair the subcommittee that handles NOAA.

For Cruz especially this position will challenge him to prove his tea party credentials. If he is in favor of private space as much as he claims, we will see him work to trim SLS, a pork project with no hope of achieving anything in space, and favor the commercial space effort, even though SLS brings much more pork into his state.

Dragon reaches orbit

3:00 am

Another successful Falcon 9 launch for SpaceX this morning, placing a Dragon capsule in the correct orbit for rendezvous and berthing with ISS.

We still await word on the attempt to land the first stage of the rocket on a barge in the Atlantic. From the link above: “SpaceX founder Elon Musk has tweeted an update: ‘Rocket made it to drone spaceport ship, but landed hard. Close, but no cigar this time. Bodes well for the future tho.'” More details here.

Based on what they have released, SpaceX has achieved something pretty incredible for its first attempt, actually hitting the floating ship at landing. That the landing itself was not soft or gently is literally only a detail. They will have the opportunity on future launches to get it right.

Europe reconsiders reusability in its rockets

8:45 am

The competition heats up: Pressured by SpaceX, Europe has restarted a research program into developing a reusable first stage to its rockets.

The headline is actually an overstatement. The European managers quoted in the article actually spend most of their time explaining why trying to reuse a rocket’s first stage makes no sense, but they feel forced to reluctantly look into it anyway because of what SpaceX is doing with its Falcon 9.

This story makes me think of two blacksmiths around 1900. One poo-poos cars, saying that the repair cost is so high no one will ever buy them. He goes back to pounding horseshoes. The other decides that if he learns how to fix cars, he can turn his shop from fixing horseshoes to fixing cars, and make more money. Europe is the first blacksmith, while SpaceX is the second.

Which do you think is going to succeed?

Some details on the SpaceX’s attempt to land its Falcon 9 first stage

8:38 am

This SpaceX press release gives some good info on the difficulty they face getting the first stage on Tuesday’s Dragon launch to land successfully on its floating sea platform:

To complicate matters further, the landing site is limited in size and not entirely stationary. The autonomous spaceport drone ship is 300 by 100 feet, with wings that extend its width to 170 feet. While that may sound huge at first, to a Falcon 9 first stage coming from space, it seems very small. The legspan of the Falcon 9 first stage is about 70 feet and while the ship is equipped with powerful thrusters to help it stay in place, it is not actually anchored, so finding the bullseye becomes particularly tricky. During previous attempts, we could only expect a landing accuracy of within 10km. For this attempt, we’re targeting a landing accuracy of within 10 meters.

They are going to try however, and they will be filming their attempt all the way. Stay tuned for some very interesting footage.
