My heart be still: Virgin Galactic has done its first taxi test of its new SpaceShipTwo, named Unity.
They have also received from the FAA a permit to do the spacecraft’s first flight tests this fall.
The competition heats up: Russia has signed its first international contract for its new still-underdevelopment Angara rocket.
Leading Russian rocket developer, GKNPTs Khrunichev, signed up the first foreign commercial passenger for the light version of its new-generation Angara rocket. The South-Korean Kompsat-6 remote-sensing satellite (a.k.a. Arirang) was booked for a ride on the Angara-1.2 launch vehicle from Plesetsk around 2020. Equipped with a Synthetic Aperture Radar, SAR, the 1.7 ton spacecraft should be inserted into the Sun-synchronous orbit.

An evening pause: At different performance of this song on youtube, Sheeran tells the audience that for this song to work “we’ve all got to be very very very quiet.” I agree. Take the time to listen quietly.

The competition heats up: In preparing its Dream Chaser engineering test vehicle for glide tests in California this fall, Sierra Nevada unveiled it to the press yesterday.
This is essentially the test vehicle’s first public viewing since its one glide test, when the front landing gear did not deploy correctly and the vehicle was damaged during landing. Since the landing gears were not the gears being developed for the flight craft, and since the glide test itself went well, both the company and NASA considered that glide test to be a success.
It has now been refurbished for new tests in conjunction with the company’s contract to use Dream Chaser as a cargo ship for NASA.
The competition heats up: SpaceX has completed a full duration test firing of one of its recovered first stages.
The JCSAT-14 stage [which was the third recovered stage and the second to land on a barge] isnโt expected to fly again due to the initial evaluations into damage received via its high-velocity return. However, it will still provide useful test data. โMost recent rocket took max damage, due to very high entry velocity,โ noted Elon Musk. โWill be our life leader for ground tests to confirm others are good.โ
That testing on the JCSAT-14 booster began on Thursday, with the stage placed on the test stand at McGregor โ ironically after the stand was vacated by the JCSAT-16 first stage โ which recently completed testing and has since been shipped to Florida for its launch next month. The returned stage is also sported a new cap, which may be providing some simulated weight to aid the required data gathering during the test firing.
The booster conducted a long firing of 2 minutes 30 seconds (the duration of first stage flight), that began around 7pm local time on Thursday (per L2 McGregor), which will provide vital data on the returned stage as SpaceX continue preparations for validating one of its recovered booster for a re-launch later this year.
It is once again important to point out that SpaceX’s engineers here have an enormous advantage over every other rocket engineer who has ever lived. They have in hand a recovered first stage that was actually used to launch a satellite into orbit, giving them the ability to test it and find out precisely how such equipment fares during launch. This will give them the ability, unavailable to others, to make engineering improvements that will make future first stages even more reliable and reusable.
An evening pause: This appears to a rehearsal for the 1973 BBC show, A Little Touch of Schmilsson, with Frank Sinatra’s arranger Gordon Jenkins.

The competition heats up: A ULA Atlas 5 rocket today successfully launched a National Reconnaissance Office (NRO) surveillance satellite, dubbed NROL-61.
The image on the right is courtesy of Orbital ATK. From the link above:
NROL-61, however, launched atop an Atlas V 421 rocket, a configuration that has not previously been used by the NRO. The spacecraft itself was encapsulated within an Extra-Extended Payload Fairing (XEPF) โ at 14 metres (46 feet) in length the longest of three available four-metre (13-foot) diameter fairings โ which has also never before been used for an NRO mission.
…The most likely explanation is that NROL-61 will be the first in a new generation of Quasar satellite; which would appear to be larger in both size and mass than its predecessors. Quasar, also known as the Satellite Data System, or SDS, is a constellation of communications satellites operated by the NRO to support its other intelligence-gathering activities; relaying data from other satellites to the ground in real-time, without having to wait for the intelligence-gathering satellites to pass over ground stations on friendly territory. If NROL-61 represents a new version of Quasar, it will be the fourth generation of the constellation.
At a meeting of NASA’s Advisory Council yesterday a NASA official estimated that SpaceX will probably spend about $300 million on its Dragon mission to Mars.
Asked by the committee how much SpaceX was spending, Reuter indicated that the companyโs investment was 10 times that of NASA. โThey did talk to us about a 10-to-1 arrangement in terms of cost: theirs 10, ours 1,โ he said. โI think thatโs in the ballpark.โ Given NASAโs investment, that implies SpaceX is spending around $300 million on Red Dragon.
SpaceX has not disclosed its estimated cost of the mission, or how it will pay for it. โI have no knowledgeโ of how the company is financing the mission, Reuter said when asked by the committee.
I suspect that the guess is significantly wrong. NASA is providing $32 million. SpaceX plans to charge customers $90 million for a single Falcon Heavy launch, which means its cost for that launch is likely half that, say $45 million. That adds up to $77 million. The cost for a Dragon capsule is not even close to $223 million, which is what remains if NASA’s guess is right, which based on this rough estimate I seriously doubt. I would bet that a single Dragon probably costs far less than $20 million. Remember, they are nothing more than basic manned capsules, and SpaceX is building enough of them to almost have an assembly line going.
So, let’s round up and say that the cost for the mission is really about $100 million (including NASA’s contribution). Other costs, such as the staff to run the mission for at least a year, will increase this cost, but not enough to bring the total to NASA’s guess of $300 million. I suspect that SpaceX will not spend anything close to $100 million of its own money for this Dragon mission to Mars.
All in all, this amount of investment seems reasonable, based on the scale of costs in the launch industry. And SpaceX’s willingness to invest some of its own money for this mission is probably wise. In publicity alone it is priceless.
An evening pause: Waterholes Canyon is a side canyon leading down into the Colorado River, north of the Grand Canyon. The people canyoneering here are caving friends of mine. The video was created by Kimberly Franke, whom you pretty much only see in the opening still shot, since she was wearing the camera most of the time. Her husband Kevin Franke is also a fellow caver who is the person with the white helmet and thick whitish beard. The woman in the red helmet doing the very long drop near the end is Belinda Norby, also a fellow caver. The music is “Point of No Return” by Roger Subirana Mata.
The world is filled with amazing things to see. This video does a nice job of highlighting just one of them.
China has built the world’s largest amphibious plane, designed initially for rescue and fire-fighting duties.
Made by the state’s aircraft maker, the AG600 is around the size of a Boeing 737 and will be used to douse forest fires and rescue people in danger offshore. Measuring 37 m (121 ft) long with a wingspan of 38.8 m (127 ft), the gargantuan amphibious aircraft is capable of taking off and landing both on terra firma and stretches of water, provided they are more than 1,500 m long, 200 m wide and 2.5 m deep (0.93 mi, 656 ft and 8.2 ft). It has a maximum take-off weight of 53.5 tonnes (59 tons), a top cruising speed of 500 km/h (310.7 mph) and a range of 4,500 km (2,800 mi), and can fly for 12 hours at a time, according to its builder, the Aviation Industry Corporation of China (AVIC).
Much like the Russians, the Chinese aerospace industry is controlled and supervised by the government. Unlike the Russians, however, the Chinese for the moment seem much more capable under this top-down system to develop new designs. They say for example that this new amphibious plane already has 17 domestic orders.
I must admit to a bit of skepticism however. Was this plane built because there was a demand, or because the powers-that-be decided they wanted it built? I am not sure. The video at the link suggests to me the latter, with its hard core sales pitch similar to a lot of other government projects I have seen, where the project is built because some politician or bureaucrat conceived and pushed it, but it doesn’t really have a viable purpose.
