In a test of a system to wirelessly transmit electricity from solar power stations in orbit, researchers from Caltech have succeeded in transmitting a small amount of electricity from an orbiting cubesat launched in January.
“Through the experiments we have run so far, we received confirmation that MAPLE can transmit power successfully to receivers in space,” [professor Ali] Hajimiri says. “We have also been able to program the array to direct its energy toward Earth, which we detected here at Caltech. We had, of course, tested it on Earth, but now we know that it can survive the trip to space and operate there.”
This small scale test mainly proved the technology can survive launch, operate in space, and transmit power back to Earth. Whether the rate of transmission can be profitable remains as yet unknown. Nor is it yet known the effects such energy transmissions through the atmosphere will have.
The German rocket startup Rocket Factory Augsburg on June 2, 2023 successfully completed a full duration engine test of the upper stage of its rocket.
Launch service provider Rocket Factory Augsburg AG (RFA) has successfully hot fired its upper stage for a full duration of 280 seconds. This marks the successful completion of the Integrated System Test (IST) campaign, in which a staged-combustion Helix engine was integrated into an upper stage tank system and hot fired several times up to full duration in the final test. This is the 1st time in Europe that a privately developed staged combustion upper stage has been successfully hot fired.
The company will also use the Helix engine in its first stage, so this test essentially proved its capability for that use as well. With this success, the company will now start constructing the first stage, with the first launch of the entire rocket targeting the end of this year.
Two important tidbits about this story. First, the test was done at a private testing facility in Germany. In the past all such testing was done under the control of the the European Space Agency, at its sites. Germany has essentially now broken that monopoly in its push to develop its own independent rocket industry of competing private companies.
Second, the launch is presently aiming to take off from a launchpad the company has leased and is building at the new Shetland Island spaceport in the United Kingdom. I wonder if it will have the same regulatory problems as Virgin Orbit in getting its launch permit. If so, that launch won’t happen this year.
Capitalism in space: SpaceX this morning successfully launched another cargo Dragon freighter to ISS, lifting off on a Falcon 9 rocket from Cape Canaveral.
This cargo capsule is on its fourth flight. The first stage completed its fifth flight, landing on a drone ship in the Atlantic. The capsule carries about 7, 000 pounds of supplies, including another set of new solar arrays for ISS, and will dock with ISS tomorrow.
The leaders in the 2023 launch race:
38 SpaceX
20 China
8 Russia
5 Rocket Lab
American private enterprise now leads China 43 to 20 in the national rankings, and the entire world combined 43 to 36. SpaceX by itself leads the world 38 to 36, but when you add other American companies it still trails everyone else combined 38 to 42.
SpaceX this morning successfully launched another 22 2nd generation Starlink satellites into orbit, with its Falcon 9 rocket lifting off from Cape Canaveral at 8:20 am (Eastern).
The first stage completed its third flight, landing successfully on a drone ship in the Atlantic. The two fairing halves completed their sixth and ninth times respectively.
The company had hoped to follow this launch with a second from Cape Canaveral only hours later, sending a new Dragon cargo freighter to ISS, but that launch was scrubbed due to weather concerns later in the day. It has been rescheduled for tomorrow.

An evening pause: Heavy tech (literally) that makes everything go, was built with slide-rules and pencils — in feet, inches, ounces, and pounds — and still operates.

NASA and Boeing revealed today that two newly discovered design issues involving Starliner’s parachutes and the tape used to protect the capsule’s wiring has forced it to cancel the planned June launch, with no firm new launch date scheduled.
The parachute issue involves the parachute cords, specifically the “soft link joints” that connect those lines to the capsule.
[Mark Nappi, Boeing’s Starliner VP] told reporters fabric links that join the parachutes to the lines of the spacecraft, called soft link joints, need to be replaced and possibly recertified to withstand heavier loads and stresses to ensure crew safety. “They were tested recently because of a discovery that we found during the review process where we believed that the data was recorded incorrectly,” Nappi said. “We tested (the soft links), and sure enough, they did fail at the lower limit.” [emphasis mine]
The tape — which has been found to be far more flammable than expected — is difficult to fix.
The second problem found last week is more extensive since the tape used to protect Starliner’s wiring harnesses from nicks or abrasions runs for hundreds of feet through several of the spacecraft’s internal systems. “There is a lot of tape on the wire harnesses,” Nappi said. “We’re looking at solutions that would provide for potentially another type of wrapping over the existing tape in the most vulnerable areas that reduces the risk of a fire hazard.”
That both of these issues were not fixed in development is beyond astonishing and speaks so badly of Boeing’s engineering and management that it is difficult to find words. In fact, for Boeing to use tape that could cause a fire now, more than a half century after the Apollo 1 capsule fire, suggests a level of incompetence that makes one wonder why anyone would ever fly on any of its spacecraft or airplanes. This is certainly not the company that built the 747.
Officials indicated that they might be able fix this issues fast enough that a fall launch could occur, but made no promises.
For Boeing, this new delay only worsens its bottom line. It built Starliner on a fixed-price contract, so every delay and issue must be paid for by it, not NASA. Meanwhile, the delays mean that SpaceX is getting flight contracts to ISS from NASA, contracts that Boeing would have gotten had Starliner been ready as planned. Worse, ISS is now looking at a 2028 retirement. If Boeing doesn’t get Starliner operational soon, there might not even be any contracts for it to win.
I have embedded the full press conference below for those who wish to watch NASA and Boeing officials blather about how they really haven’t done anything stupid here. Really, you have got to believe them!

After two years dealing with regulatory delays, Viasat has finally completed its purchase of Inmarsat, producing a single company that has 8,000 employees and a fleet of nineteen operating satellites.
The key quote from the link however is this:
Their merger announcement sparked additional consolidation plans as operators look to bolster their defenses amid a growing competitive threat from Starlink in the satellite broadband market. Eutelsat announced plans to buy OneWeb in November 2022 and hopes to complete its merger this summer. SES and Intelsat confirmed March 29 they were in talks about merging, although they have not provided a meaningful update since then.
In other words, the older geosynchronous satellite companies are consolidating because of the competition posed by SpaceX’s Starlink system, which also suggests these companies have never competed very aggressively against each other to cut costs. Now that someone new (SpaceX) has arrived doing that, they find their only option is to merge. Apparently the corporate culture in each separate company finds cutting costs difficult. Merger appears to be their only avenue for doing so.
I wonder what will happen to these old satellite companies when (or if) Amazon finally begins launching and operating its own Kuiper constellation, in direct competition with SpaceX. Unless they finally begin to offer a competitive product at a competitive price, I expect after consolidation we will begin to see bankruptcies.
Sierra Space yesterday announced that it has successfully run electricity for the first time through its first Dream Chaser mini-shuttle, dubbed Tenacity.
The press release is remarkably lacking in detailed information, or graphics. This quote is really the only hard facts mentioned:
Sierra Space simulated the power that will be generated from Dream Chaserβs solar arrays once on orbit. Test engineers plugged that power into Dream Chaser and began turning on systems. Sierra Space exercised flight computers, base processors and low-voltage distribution units.
Tenacity has been under construction since 2016, when the company won its NASA contract to build it. That’s seven years to build a single spacecraft, and yet all they have done so far is feed electricity through it for the first time. In that time period SpaceX not only built multiple prototypes of Starship and Superheavy, it has flown multiple test flights.
Is money an issue? The actual contract amount NASA gave Sierra Space to build Tenacity has never been published, though NASA has said the total awarded for all the cargo missions to be flown by SpaceX, Northrop Grumman, and Sierra Space equaled $14 billion. Since these fixed price contracts also require the companies also commit some of their own funds, or obtain outside financing, it is possible that Sierra Space has had money issues slowing development.
Regardless, Dream Chaser was first supposed to fly in 2020. It is now three years late, with no clear indication that a launch will come anytime soon. In many way, Sierra Space is beginning to remind me of Blue Origin, endlessly issuing promises but never delivering.

In a ceremony yesterday in Spain, that country became the 25th nation to sign the Artemis Accords, a bi-lateral agreement with the United States that was designed during the Trump administration to act as a work around to the limitations to private enterprise in space created by the Outer Space Treaty.
The full list of signatories so far: Australia, Bahrain, Brazil, Canada, Columbia, Czech Republic, France, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, South Korea, Spain, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.
This alliance gives the United States a great deal of leverage in establishing legal policy, if it is used as originally intended. It however at present remains unclear if the Biden administration intends to do so, considering its general hostility to the private sector and freedom.
