Sarah Brightman, astronaut
The competition heats up: The start of Sarah Brightman’s astronaut training has been delayed from this fall to the beginning of 2015.
I suspect this delay has more to do with accommodating her schedule and the fact that she is very enthusiastic and well-prepared than any negative issues related to her or the mission. They have probably decided that she just needs less time to train.
Her actual flight to ISS is scheduled for the fall of 2015.

SpaceX sets the next Falcon 9 commercial launch date
SpaceX has scheduled the next commercial launch of its Falcon 9 rocket for this coming Saturday.
They have completed their review of the Falcon 9R test failure and have obviously concluded that its problems will not effect the Falcon 9.

Vladimir Putin, space cadet
Two news stories today demonstrate without question that Russia’s newly reorganized aerospace industry and its project to build a new spaceport are not merely the efforts of mid-level bureaucrats in that aerospace industry.
No, these efforts have been instituted and are being pushed at the very top of the Russian government, by Vladmir Putin himself. It appears that he has decided, or has always believed, that Russia deserves a strong and vibrant space program, run from Moscow, and is doing everything he can to make it happen, as part of his personal vision for Russia.
The first story described a visit on Tuesday that Putin made to Russia’s new space port, Vostochny, in the far eastern end of Russia. While there he noted that construction is several months behind schedule and that this slack must be made up. He then endorsed the proposal put to him by space agency officials that the number of people working on construction should be doubled.
The second story described Putin’s endorsement of the construction of a new Russian heavy lift rocket, capable of putting 150 tons into orbit. Such a rocket would be comparable in power to the largest version of the U.S.’s SLS rocket, not due to be launched, if ever, until the 2020s.

Musk vs Bezos
The competition heats up: SpaceX is challenging a patent issued to Jeff Bezos’ Blue Origin for landing the first stage of a rocket vertically on a floating platform.
“The ‘rocket science’ claimed in the ‘321 patent was, at best, ‘old hat’ by 2009,” says SpaceX in one of two challenges, filed last week with the U.S. Patent Trial and Appeal Board following the approval of the Blue Origin patent in March. SpaceX cites prior work by researchers and scientists who proposed techniques similar to those in Blue Origin’s patent.
If the patent holds it might force SpaceX to pay Blue Origin for the right to bring its Falcon 9 first stage back safely,

Battle of the heavy lift rockets
Check out this very detailed and informative look at unstated competiton between NASA’s SLS rocket and SpaceX’s heavy lift rocket plans that are even more powerful than the Falcon Heavy.
Key quote: “It is clear SpaceX envisions a rocket far more powerful than even the fully evolved Block 2 SLS – a NASA rocket that isn’t set to be launched until the 2030s.”
The SpaceX rocket hinges on whether the company can successfully build its new Raptor engine. If they do, they will have their heavy lift rocket in the air and functioning far sooner than NASA, and for far far far less money.

The decision on manned spaceflight
The rumors are swirling. Today alone the news included three different articles about NASA’s upcoming decision to down-select to either one or two in its manned commercial crew program.
- Is this the space vehicle that will be NASA’s alternative to Russia’s ‘taxi service’ to orbit?
- First Class or Economy?—NASA’s countdown in the new space race [subscription required]
- Decision on commercial crew program likely to be made after Labor Day weekend
The third article above speculates that the decision will be made shortly after this weekend, maybe as soon as next week. It also outlines in nice detail the companies who are competing for the contract.
I strongly expect NASA to pick two companies, not one, as the agency has repeatedly said it wants to have redundancy and competition in manned space flight. To this I agree whole-heartedly. Right now, if I was a betting man (which I am not), I would pick SpaceX and Sierra Nevada as the two companies to get the nod.
If NASA only picks one company that I don’t think there is much doubt that it will be SpaceX.
And then again, government agencies, because of politics, have sometimes made some incredibly stupid decisions. For example, back in the 1970s the company that proposed the space shuttle was rejected for another big space company that had more political clout, which then turned around and essentially stole the first company’s designs to build the space shuttle from them. It just took longer and cost more.

Single sensor caused Falcon 9R failure
SpaceX has identified the cause of the failure of last week’s Falcon 9R test flight failure as a single sensor.
On the Falcon 9R, there was no backup for this sensor, so the rocket was required to self-destruct when the sensor failed. On a Falcon 9, other sensors would have picked up the slack and the rocket would have continued in flight.
That the sensor is used by the Falcon 9, however, explains why they have delayed the next commercial flight. They probably want to make sure they understand why the sensor failed so they can reduce the chance of failure on the Falcon 9.

A new SpaceShipTwo glide test flight
SpaceShipTwo successfully completed an unpowered glide test yesterday, testing the dynamics and plumbing of the ship’s new engines.
They pumped inert liquid through the plumbing to make sure it functioned in flight. The flight itself tested the balance and position of the new engine.
Assuming the results from these tests are good, expect powered flights quite soon.

A tugboat for satellites
The competition heats up: An Israeli start-up is building a satellite tugboat that could be used to move stranded satellites to their proper orbits.
The planned satellite, once built and deployed, should be able to rendezvous with in-orbit satellites and propel them into new orbits, give them course corrections, or steer them towards what’s known as the “graveyard orbit” – a decommissioned satellite graveyard some 300km above their usual height of 36,000 kilometers over the equator. This fuel saving can extend a communications satellite’s life.
The company says its tugboat design could be a possible solution to two stranded Galileo Project satellites, now in possibly unusable orbits following a launch malfunction over the weekend.
The spacecraft would use an ion engine for propulsion.

Antares to launch polar orbiting satellites?
The competition heats up: Orbital Sciences expects within a year to get government approval to use its Antares rocket to launch sun-synchronous satellites from its launch facility at Wallops Island, Virginia.
Currently Antares is used to launch cargo resupply missions to the international space station, whose orbital inclination — the angle at which it passes over the equator — of 51.6 degrees dictates that the rocket follow a southeasterly flight path over the Atlantic Ocean. To reach high-inclination orbits, the vehicle would presumably need to fly more directly toward the equator.
Among the details to be settled is the exact configuration of the Antares rocket Orbital would use to place satellites into sun-synchronous orbits, which are commonly used for Earth observation missions. The Antares rockets flown to date have been two-stage vehicles, but the company offers three-stage versions for missions with more stringent orbital-insertion accuracy or high-energy requirements.
The issue here is making sure the rocket stays clear of population areas during launch. An almost due south launch path, needed for polar orbit from Wallops Island, would pass this test.

SpaceX scrubs Wednesday commercial launch
SpaceX has scrubbed a commercial launch that had been scheduled for Wednesday.
No explanation was provided, but it is likely that the company and its commercial partners decided to give themselves more time to study the issues that caused the Falcon 9R test rocket to destroy itself on Friday.

A new Falcon 1 to compete against SpaceX
The competition heats up: A rocket launch start-up created by former SpaceX engineers seeks to build their own Falcon 1 rocket for the small satellite market.
Their rocket, called Firefly, will use a number of new and old technological ideas. The highlighted words in this paragraph, however, stood out to me the most:
Just as Firefly is drawing on a lot of government research in its aerospike technology, the company is using a key element of the SpaceX Merlin engine—the pintle injector—in its new engine’s combustion chamber. Markusic, who jumped ship from NASA to SpaceX after the agency sent him to Kwajalein Atoll in the Marshall Islands to observe the first flight of the Falcon 1, says he started working on the technology—also used on the Apollo program’s lunar-descent engine —at SpaceX and when he was developing a liquid-fuel alternative to the hybrid engine used on Virgin Galactic’s SpaceShipTwo. [emphasis mine]
It only took one trip to see SpaceX in operation for this NASA engineer to become a former NASA engineer.

SpaceX delays commercial launch 24 hours
SpaceX has delayed its next commercial launch one day to Wednesday in order to make sure the issues that caused its Falcon 9R test rocket to self-destruct are irrelevant to the full Falcon 9 rocket.
Seems like a prudent decision that is also not overly timid. If this had been the NASA of the past few decades, they would have generally delayed the launch for far longer.

Soyuz puts two satellites in wrong orbit
A Russian-made Soyuz rocket launched from French Guiana for Arianespace has placed two European Galileo GPS satellites into the wrong orbit.
Russianspaceweb suggests that the problem was caused by the rocket’s Russian Fregat upper stage. (Scroll down about halfway to read their report on this launch.)
Multiple independent sources analyzing the situation suggested that the Fregat upper stage had fired its engine for the right duration, however the stage’s orientation in space during the second or both maneuvers had probably been wrong. According to Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics and a veteran space historian, the Fregat’s angular orientation error during engine firing could reach as much as 145 degrees.
This failure is a triple whammy. It hits both Arianespace and Russia since the Soyuz was part of a partnership between the two. It also hits Europe’s Galileo GPS satellite, which after many years of development was beginning to move towards full operation.

Falcon 9R destroyed during failed test flight
In a test flight today of SpaceX’s Falcon 9R vertical take off and landing rocket the rocket was destroyed when ground controllers detected an “anomaly.”
Falcon 9R is a three engine version of the Falcon 9 first stage, designed to test designs for making that first stage capable of landing vertically. It has flown successfully a number of previous times, but this time it appears something was not quite right during the flight and ground controllers had to destroy it for safety reasons.
Is this a set back? Of course. Is it a failure? Not really, as it was a test flight of very cutting edge technology and even failures will teach you something to improve the engineering.
