The plundering of NASA

3:30 pm

From one of my readers: The Plundering of NASA: an Expose, How pork barrel politics harm American spaceflight leadership. You can buy the ebook edition here, and the print edition here.

I just finished reading it. Boozer’s introduction and opening two chapters provide one of the best detailed summaries explaining clearly why the United States today cannot launch its own astronauts into space, and why we are threatened with the possibility that we won’t be able to do it for years to come. And while his perspective is mostly from an engineering perspective, he also gives some of the political background behind this situation.

His later chapters are not as effectively written, but the opening is still worth it.

I will give a hint about his thesis: it involves comparing the Space Launch System (SLS) with private commercial space. And SLS does not fare well.

Robot engineers have successfully built a fleet of small flying robot helicopters that can fly individually or as complex large arrays.

Robot engineers have successfully built a fleet of small flying robot helicopters that can fly individually or as complex large arrays. With video.

Applying this biologically-inspired solution to swarms of robots could enable a wide range of applications. Swarms of robots could be used to explore other planets, or search a large area for a missing person. When a larger payload needs to be lifted, groups of robots would combine to make a larger flying platform and when that job was done, disperse into smaller groups that can cover a larger area. The advantage of distributed control in these scenarios is that there is no vulnerable central control unit which, if taken out, could bring down the entire mission.

With Proton rocket’s most recent launch failure, Inmarsat looks for alternatives.

3:15 pm

The competition heats up: With Proton rocket’s most recent launch failure, Inmarsat looks for alternatives.

The failure and its spectacular nature, all caught on video — oscillating trajectory on liftoff before tipping over, bursting into flames and then crashing — cast a harsh light on Inmarsat’s sole-source decision for the Global Xpress satellites. The company’s stock tumbled on the London Stock Exchange but has since recovered as details emerged about the relatively easily addressed causes of the rocket’s failure.

Inmarsat officials said at the time of the ILS contract award that they received an exceptionally low price in return for booking all three launches on Proton and that the vehicle’s record justified the choice not to include a second vehicle in the Global Xpress mix.

In celebration of the 10th anniversary of the launch of Opportunity, Mars Reconnaissance Orbiter took its photograph.

The image was not merely for PR. It also provides the scientists operating Opportunity some good information about the region the rover is exploring, thus helping them plan out its further adventures on the surface of Mars.

The Russians admitted today that, due to the Proton launch failure two weeks ago, only five more Proton launches can occur this year.

Before the crash they had hoped to get in about nine launches, more than one per month, all of which were commercial in nature. It was my impression that this launch rate was an effort to provide service to their customers as fast as possible, in order to hold on to them. The crash, like the previous Proton failures in the past few years, has given their competitors a window of opportunity to grab the Russian market share. If SpaceX is successful in its first commercial launch in September the competition in this industry will certainly heat up.

Russia confirms that a Proton rocket failed at launch two weeks ago because three of six sensors were installed upside down.

Russia confirms that a Proton rocket failed at launch two weeks ago because three of six sensors were installed upside down.

They are going to subject the personnel involved to lie detector tests in order to find out who did what. We should then expect them to prosecute those individuals. Unlike the U.S., they won’t simply fire them.

SpaceX has renegotiated its lease with the city of McGregor, Texas, in order to begin testing the Falcon Heavy rocket.

The competition heats up: SpaceX has renegotiated its lease with the city of McGregor, Texas, in order to begin testing the Falcon Heavy rocket.

What I found stunning about this article is this quote:

The Falcon Heavy will have commercial, civil and national security applications, Ra said, adding that customers will pay $81 million to $135 million per launch, depending on the weight of the payload and the rocket’s destination. That is about twice the price of a Falcon 9 launch.

These prices for the Falcon Heavy are actually comparable or cheaper than that charged by most other rocket companies for geosynchronous launches. If SpaceX succeeds in doing this — launching Falcon Heavy at these prices — they will certainly open deep space to private enterprise. And even if their prices end up being twice this, those prices will still be anywhere from one fourth to less than a tenth of what it will cost NASA to launch its SLS rocket.

Which should make us all wonder: Why is anyone in Congress still voting to fund SLS?

The competition heats up: SpaceX has successfully completed a full duration test firing of 9 upgraded Merlin engines.

The full mission duration firing of the next generation Falcon 9 booster was completed on Sunday. The booster’s nine Merlin 1D engines fired for approximately three minutes, simulating what the booster may experience in flight before stage separation.

With this success, I suspect they are finally ready to begin their commercial launches. The first is presently scheduled for September 5.

The competition heats up: Orbital Sciences has issued an update on its Antares launch schedule, with the launch window for the Cygnus demonstration mission to ISS now set for September 14-19.

They announced this on July 10, but I am only now catching up. The launch could happen sooner, if there are delays to the launch of NASA’s LADEE moon probe. Right now the two launches are coordinated to have LADEE launch first.

The competition heats up: Sierra Nevada has completed its first tow tests of its Dream Chaser engineering test vehicle, now officially named “Eagle.”

These tests were merely to check out the craft’s landing systems, with it being pulled along the runway at 10 to 20 mph. Faster tests, followed by actual drop tests, are to follow.

The article has some great information about Dream Chaser itself.

The Russian investigation into the crash of their Proton rocket on Tuesday now includes a criminal prosecutor.

“The investigative department of the Russian Investigative Committee at the Baikonur complex has opened a criminal case on this incident over evidence of a crime, put forward in the Russian Criminal Code Article 216 Part 1. The Baikonur prosecutor’s office is overseeing the investigation,” the statement said.

There is also another story from this news service claiming that the crash occurred because the rocket launched a half second early, confusing its computer systems.

This week’s launch failure of the Proton rocket leaves two satellite communications firms in a quandary.

5:05 pm

The competition heats up: This week’s launch failure of the Proton rocket leaves two satellite communications firms in a quandary.

Luxembourg-based SES joins London-based Inmarsat among the commercial customers awaiting Proton launches later this year, a prospect that almost certainly disappeared in the fireball that engulfed Proton shortly after liftoff from the Baikonur Cosmodrome in Kazakhstan. Inmarsat’s entire next-generation high-speed mobile communications product offer is booked on three Proton launches.

It appears that their only other launch options are Arianespace, which is booked up, and SpaceX, which is not yet ready to take on this much new business.

In other words, the launch industry has a need for more launchers from companies willing to compete for that business.

Update: Arianespace has said that if they get the orders quickly, they might be able to fit the launch’s into their 2014 launch manifest. That has the sound of a company that wants to make money, and is willing to do whatever it takes to capture the business.

NASA has revised their plans for the 2017 and 2021 flights of its Orion capsule, making both flights more ambitious.

9:33 am

The competition heats up? NASA has revised their plans for the 2017 and 2021 flights of its Orion capsule, making both flights more ambitious.

[M]anifests have always pointed towards the first SLS/Orion launch being an uncrewed Exploration Mission (EM-1), which was baselined a validation flight that would send Orion on a 7-10 day mission around the Moon.

SLS and Orion would then endure a four year gap – again, mainly due to the advanced 2017 debut relating to ISS crew back up – before repeating a version of EM-1, this time as a CLO (Crewed Lunar Orbit) flight, with four astronauts spending three to four days orbiting our nearest neighbor, as opposed to heading directly home after passing around the Moon – a flight known as Exploration Mission -2 (EM-2).

Much to the surprise of some people deeply involved with SLS and Orion, the order came down from NASA HQ to realign EM-2, based around a 2019 mission tasked with hunting down and capturing an asteroid that would then be placed in the vicinity of the Moon within one to two years. EM-2 is also known as the Asteroid Redirect Crewed Mission (ARCM). [emphasis mine]

It has been my understanding that the plans for the 2017 unmanned test flight have previously described it as sending the Orion capsule into a high several thousand mile orbit, not to the Moon, in order to simulate a re-entry from lunar distances. Making that unmanned mission a lunar orbital mission makes it far more challenging. Similarly, it is incredibly risky to turn the next flight, the first manned flight for Orion, into a duplicate of this mission, or a flight to an asteroid. This will be the first time humans will have ever flown on Orion, and only the second time the capsule has been used. To then send those humans to the Moon or an asteroid seems downright foolish. Even the 1960s NASA, which was quite willing to run risks, would not have attempted such a plan.

It is my guess that the White House has recognized that SLS can’t survive politically with a launch rate once every four years and planned test flights that aren’t very exciting. They are therefore pushing NASA to accelerate the second mission (and first manned flight) from 2021 to 2019, while also making both flights more ambitious and therefore more salable to the public.

Whether this is possible, given NASA’s bloated bureaucracy, is the main question. Moreover, even at this accelerated pace SLS will be competing directly against the private sector, which I expect will continue to do things far faster and, more importantly, far cheaper. Against that competition SLS will be hard put to survive.

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.

The Kickstarter campaign by the private company Planetary Resources has made its $1.5 million goal.

The competition heats up: The Kickstarter campaign by the private company Planetary Resources has made its $1.5 million goal.

That campaign reached its $1 million goal on June 19, opening the way for one of Planetary Resources’ Arkyd-100 space telescopes to be used for educational and personal imaging projects. The biggest crowd-pleaser was a $25 offer that will let backers take “space selfies” — orbital pictures showing a display on the telescope with an image submitted by a backer in the foreground, and Earth in the background.

The Asteroid Zoo plan was [the $1.5 million] stretch goal for the campaign. Planetary Resources will partner with Zooniverse to create a game-like online program to identify asteroids, modeled on other Zooniverse citizen-science efforts such as Galaxy Zoo, Moon Zoo and Planet Hunters. Users would be recruited to join in, and then trained to spot the telltale signs of an asteroid’s movement — for example, by “blinking” multiple images of the same patch of sky, or using more sophisticated techniques. The search would draw upon more than 3 million images from the Catalina Sky Survey.

A Russian Proton rocket went out of control and crashed mere seconds after launch today at Baikonur.

8:58 am

A Russian Proton rocket went out of control and crashed mere seconds after launch today at Baikonur.

Video below the fold. It appears the rocket’s avionics had completely failed so that the engines could no longer control its flight. Obviously that is speculation. What is clear is that the failure was not because of a problem with the rocket’s Briz-M upper stage, which has been the source of the five Proton failures during the past three years.

This is very very very bad news for the Russian commercial rocket effort. They have been trying to recover from those earlier failures, and with the string of successes this year had appeared to doing so. Instead, they now have had their worst and most spectacular launch failure in decades, so spectacular it is reminiscent of the rocket failures of the 1950s. Worse, the failure is not because of the relatively new Briz-M upper stage, but in their well established, decades old first stage, indicating that there are some fundamental quality control problems in their manufacturing process that they have not fixed.

This cannot be good for their business, especially as they have some serious competition. Arianespace, though expensive, is very reliable. SpaceX, though new and essentially untried, is very competitive in price. So is Orbital Sciences.

Expect a lot of heads to roll.

Voyager 1 has found the edge of the solar system to be far more complex than predicted by scientists.

8:44 am

The uncertainty of science: Voyager 1 has found the edge of the solar system to be far more complex than predicted by scientists.

Scientists had assumed that Voyager 1, launched in 1977, would have exited the solar system by now. That would mean crossing the heliopause and leaving behind the vast bubble known as the heliosphere, which is characterized by particles flung by the sun and by a powerful magnetic field.

The scientists’ assumption turned out to be half-right. On Aug. 25, Voyager 1 saw a sharp drop-off in the solar particles, also known as the solar wind. At the same time, there was a spike in galactic particles coming from all points of the compass. But the sun’s magnetic field still registers, somewhat diminished, on the spacecraft’s magnetometer. So it’s still in the sun’s magnetic embrace, in a sense.

Kepler’s planet-hunting predecessor, COROT, has been shut down.

8:33 am

Kepler’s planet-hunting predecessor, CoRoT, has been shut down.

CoRoT suffered a computer failure on November, 2, 2012 and although the spacecraft is capable of receiving navigational commands, the French Space Agency CNES reports it can no longer retrieve data from its 30-centimeter telescope. After a valiant effort to try and restore the computer, CNES announced this week that the spacecraft has been retired. CoRoT’s journey will come to a fiery end as it will be deorbited and it will burn up on re-entry in Earth’s atmosphere.

CoRoT found 32 exoplanets with at least a hundred more candidates still to be confirmed.
