SpaceX successfully catches both fairings from a launch
Capitalism in space: For the first time SpaceX yesterday successfully caught both fairings halves in the nets of their ships as they floated down to the ocean on their parasails.
Previously they have mostly plucked the fairings from the sea, though they have caught a few in the netting of the ships. To catch both simplifies the preparation for the next flight enormously, as they never touched the water.
MeTrónomoS – One Small Step
An evening pause: For this anniversary of Neil Armstrong’s first step on the Moon, a short musical piece, with images, that nicely encapsulates that 1960s space effort. If you are passionate about the human effort to become a space-faring civilization and you don’t know who and what mission each clip portrays, you need to find out.
SpaceX successfully launches South Korean military satellite
Capitalism in space: SpaceX today successfully launched a South Korean military satellite, with its Falcon 9 rocket using the same first stage that launched two American astronauts to ISS less than two months ago.
This was the company’s fastest turnaround yet of a used first stage, 51 days, which also beats the fastest turnaround ever by the shuttle program, 54 days. And as you can see by the screen capture image to the right, they successfully landed it so that it can be used for a third time.
Watching the camera on that first stage after separation (on SpaceX’s live stream) to landing was most fascinating. After separation its tail end points down to the west and its launch site in Florida. As it curves upward and then down towards its landing in the Atlantic, its small thrusters and grid fins very slowly and gracefully swing that tail to instead point east and down to the drone ship. I had not noticed previously the gentleness of that re-positioning. The daylight clear weather today, plus excellent camera access, made it very obvious.
The leaders in the 2020 launch race:
16 China
11 SpaceX
7 Russia
3 ULA
3 Japan
The U.S. now leads China in the national rankings, 18 to 16.
British Airways retires 747 fleet
Because of the crash in customer demand due to the Wuhan virus panic, British Airways has abruptly retired its entire fleet of 747s.
This retirement had been planned, as the 747 is expensive to operate. The airline had planned however to phase them out over several years. Now they simply don’t need them, as they are flying so few passengers.
I am fortunate that I got to fly on one in 2019, in a vacation trip to Wales with Diane. This might have been the only time I ever flew on a 747, and it was a remarkably smooth flight, both during take-off and landing. It is sad to see this magnificent American achievement finally leave us.
NASA: Dragon crew will return to Earth August 2nd
Capitalism in space: Assuming that the weather cooperates, NASA has now set August 2nd as the date the manned Dragon capsule will return to Earth with its two man crew.
Assuming good weather and a smooth final few weeks on the International Space Station, astronauts Doug Hurley and Bob Behnken are scheduled to undock from the orbiting research outpost Aug. 1 and return to Earth the next day to wrap up a 64-day test flight of SpaceX’s Crew Dragon spaceship.
NASA Administrator Jim Bridenstine confirmed the target dates for the Crew Dragon’s undocking and splashdown in a tweet Friday. A few hours after departing the space station, the Crew Dragon will fire its Draco thrusters for a braking burn and re-enter the atmosphere, targeting a parachute-assisted splashdown at sea. “Splashdown is targeted for Aug. 2,” he tweeted. “Weather will drive the actual date. Stay tuned.”
Note that the recovery operations, as has been the case with everything else on this flight, will be run entirely by SpaceX and its employees. NASA’s only real role is that of a customer and observer, though obviously agency officials are taking a hands-on part in determining the landing date.

Starship prototype being prepped for first hop
Capitalism in space: SpaceX engineers, having successfully completed its tank pressure tests of its fifth Starship prototype, are now preparing the ship for its first static fire engine test, to be followed very quickly thereafter by its first hop to 150 meters.
SN5 [the fifth prototype] is being prepped for a flight test right out of the gate. SpaceX does not plan to perform an extended ground test campaign with SN5 after beginning Raptor engine testing.
It is understood that one good static fire test could be enough to clear the way for a 150-meter hop test. Furthermore, only a few days may be required to prepare SN5 for the flight test following a successful static fire test. If a static fire occurs this weekend, this will put the earliest possible hop date in the first half of next week.
As always, this schedule could change during testing.
The article also describes the status of both the sixth prototype, as well as the eighth being assembled now, noting that “if the 150-meter flight of Starship SN5 is successful, SpaceX is expected to quickly move on to Starship SN8 for an upcoming higher altitude flight test – potentially skipping a flight test with the SN6 prototype.”
Northrop Grumman launches U.S. reconnaissance satellites
Capitalism in space: Northrop Grumman today successfully used its Minotaur-4 rocket to launch four U.S. reconnaissance satellites for the National Reconnaissance Office.
Minotaur-4 is essentially re-purposed military ICBM that had been decommissioned, refurbished, and upgraded for orbital flight. This was its first launch from Wallops Island in Virginia. This was also Northrop Grumman’s second launch this year, which still leaves them out of the 2020 launch race leader board:
16 China
10 SpaceX
7 Russia
3 ULA
Today’s launch however puts the U.S. ahead of China in the national rankings, 17 to 16.

Launch delays for SpaceX and UAE
The launches planned for tomorrow by SpaceX and Japan’s space agency JAXA have both been postponed, for different reasons.
The SpaceX launch of a South Korean military satellite was postponed in order to swap out equipment in the Falcon’s upper stage. No new launch date has yet been announced.
The JAXA launch, using Mitsubishi’s H-2A rocket, was to launch the United Arab Emirates’ Mars orbiter Hope. It was postponed due to bad weather. Their next launch window is July 16, but they have not yet announced a new launch date. Like Perseverance, they must launch this summer or they will have to wait two years for the next launch window to Mars to reopen.
SpaceX about to set reuse record for fastest turnaround ever
Capitalism in space: If tomorrow’s launch of a South Korean military satellite by SpaceX’s Falcon 9 rocket succeeds, it will set a new all-time record for the fastest turnaround of a used rocket, 44 days.
The previous record was 54 days, set by the space shuttle Atlantis in 1984. The article notes however the spectacular differences:
By far the most impressive aspect of Falcon 9’s imminent record is the comparison between the resources behind Space Shuttle Atlantis’ 54-day turnaround and Falcon 9 booster B1058’s ~44-day turnaround. Around the time NASA and Atlantis set the Shuttle’s longstanding record, some 5000-10000 full-time employees were tasked with refurbishing Space Shuttles and the facilities (and launch pads) that supported them. Based on retrospective analyses done after the STS program’s end in 2011, the average Space Shuttle launch (accounting for the vast infrastructure behind the scenes) ultimately wound up costing more than $1.5 billion per launch – more than the Saturn V rocket the Shuttle theoretically replaced.
According to a uniquely detailed May 2020 AviationWeek interview with SpaceX CEO Elon Musk, Falcon 9 booster turnaround may cost as little as $1 million apiece and can be managed from start to finish by several dozen employees at most. In other words, even though SpaceX boosters are suborbital and stressed quite a bit less than orbital Space Shuttles, Falcon 9 reuse is approximately a thousandfold more efficient that Space Shuttle reuse. [emphasis in original]
I should add that SpaceX also has three more launches on tap for the rest of July. If all lift off, the company will have launched four rockets in only three weeks, which in itself will be a record. No private rocket company has ever launched so frequently and so routinely. And only Russia during its Soviet Union heydays has come close to launching with this frequency.
Midnight repost: The think tank culture of Washington
The tenth anniversary retrospective of Behind the Black continues: The essay below, first posted on June 22, 2016, was the result of a Washington DC. trip, occurring during the heat of the presidential campaign just after Donald Trump had become the Republican candidate for president.
The impression I got of the Washington culture then has sadly proven more accurate than I would have ever guessed. And their response to Trump’s election was just as I feared.

The Think Tank Culture of Washington
On Monday I attended and gave a presentation at the one-day annual conference of the Center for New American Security (CNAS) in Washington, D.C., in conjunction with the space policy paper I am writing for them, Exploring Space in the 21st Century.
CNAS was founded ten years ago by two political Washington insiders, one a Democrat and the other a Republican, with a focus on foreign policy and defense issues and the central goal of encouraging bi-partisan discussion. For this reason their policy papers cover a wide range of foreign policy subjects, written by authors from both political parties. The conference itself probably had about 1,000 attendees from across the political spectrum, most of whom seemed to me to be part of the Washington establishment of policy makers, either working for elected officials, for various executive agencies, or for one of the capital’s many think tanks, including CNAS.
I myself was definitely not a major presenter at this conference, with speakers like Vice President Joe Biden, Senator Lindsey Graham (R-South Carolina), and Senator Joe Reed (D-Rhode Island). I was part of a panel during one of the lunch breakout sessions, where approximately one third of the attendees came to have lunch while we spoke about space. I only had ten minutes to speak, and used that time to outline (1) the influence SpaceX is having on the entire launch industry and (2) the vast differences in cost, development time, and results between the Orion/SLS program and commercial space. Not surprisingly, the aerospace people from the big established companies appeared to be somewhat uncomfortable with what I had to say, though the Airbus people liked it when I made it clear I thought that the U.S. should allow foreign companies to compete for American business, including government launches.
Their discomfort was best illustrated by the one question asked of me following my talk, where the questioner said that I was comparing apples to oranges in comparing a manned capsule like Orion, intended to go beyond Earth orbit, with the unmanned cargo capsules like Dragon and Cygnus, that only go to ISS. I countered that though I recognized these differences, I also recognized that the differences were really not as much as the industry likes to imply, as demonstrated for example by SpaceX’s announcement that they plan to send Dragon capsules to Mars beginning in 2018. After all, a capsule is still only a capsule. The differences simply did not explain the gigantic differences in cost and development time.
I added that Orion compares badly with Apollo as well, noting that Apollo took about a third as long to build and actually cost less. I doubt I satisfied this individual’s objections, but in the end I think future policy will be decided based on results, not the desires of any one industry bigwig. And in this area Orion/SLS has some serious problems. I hope when my policy paper is released in August it will have some influence in determining that future policy.
My overall impression of CNAS, the speakers, and the people who attended was somewhat mixed. Having lived in the Washington, D.C. area from 1998 to 2011, when I attended many such conferences, I found that things haven’t changed much in the last five years. Superficially, everyone was dressed in formal business suits (something you see less and less elsewhere), and they also got to eat some fancy food at lunch.
On a deeper level my impressions were also mixed.

COVID-19 and launchpad issues delay Ariane 6
The European Space Agency (ESA) confirmed today that the first launch of Arianespace’s Ariane 6 rocket will be delayed at least six months, to late 2021, due to lock downs related to the Wuhan flu panic, as well as construction issues at the rocket’s new launchpad.
“While we know that the maiden flight will not take place before the second semester of 2021, we cannot at this moment precisely quantify the delay, and we cannot provide an exact launch date,” Daniel Neuenschwander, ESA’s director of space transportation, said according to an ESA translation of remarks at a July 9 press event provided to SpaceNews. The French Association of Professional Journalists in Aeronautics, organized the event at ArianeGroup’s headquarters in Paris.
ESA hopes to have greater clarity on the delays in a few months, he said, according to the ESA translation.
It bodes bad for this rocket that they, at this time, have so little handle on the issues and the length of the delays.
Midnight repost: Switching to Linux
The tenth anniversary retrospective of Behind the Black continues: My contempt for Microsoft and its terrible Windows operating system is quite well known. I successfully switched to Linux back in 2006 and have never regretted it.
After seeing a number of my posts noting the advantages of Linux (or anything) over Windows, one of my readers, James Stephens, offered to write a series for Behind the Black describing step-by-step the process by which one gets and installs Linux on either a desktop or laptop computer. Below are the links to this series. I have since used it myself as a guide to convert two used Windows 7 notebooks (purchased for about $35 each) to my favorite flavor of Linux, both of which I use regularly as my travel computers.
I wish more people would do the same. I am sure almost everyone has an old computer they don’t use anymore. It will work like new with Linux. Dig it out, follow James’ instructions, and free yourself from Windows. I guarantee you will not be disappointed.

Falcon 9 landing leg falls during retraction
Capitalism in space: During the processing to bring a used Falcon 9 first stage back to its hanger after its June 30th launch, one of the landing legs unexpectedly fell back to the ground during retraction.
I have embedded the video of the incident, cued to the event, below the fold. No one was hurt, and it appeared that nothing was damaged. It appears it happened because a cable holding the leg vertical snapped just before the leg got latched in place on the side of the rocket.
