Researchers successfully transmit electricity from space

10:22 am

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.

Astronomers think they have completed the census of Near Earth asteroids

10:14 am

Astronomers in a new paper [pdf] have concluded that the census of Near Earth asteroids is largely now complete, and have begun focusing their effort on narrowing down the list of potentially dangerous asteroids in that census. From the press release:

Researchers from CU Boulder and NASA have completed a census of hundreds of large asteroids orbiting near Earth—gauging which ones could come precariously close to our planet over the next thousand years. The researchers identified at least 20 asteroids that scientists may want to study more to make certain they pose no threat to life on Earth in the next millennium.

To be clear, the researchers say the odds of any of these rocky bodies striking the planet are extremely low, and are next to zero for the coming century. But because the fallout from such an impact would be catastrophic, it’s important to be sure, said Oscar Fuentes-Muñoz, lead author of the study. “We don’t want to alarm people, because the results are not alarming,” said Fuentes-Muñoz, a doctoral student in the Ann and H.J. Smead Department of Aerospace Engineering Sciences. “But there are a lot of uncertainties in predicting so far into the future.”

To sum up, none of those 20 asteroids has any chance of hitting the Earth in the next few hundred years. Beyond that the uncertainties make it difficult to predict. Reducing those uncertainities is now the focus of their work.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

German rocket startup successfully completes full duration engine test of upper stage

10:03 am

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.

Three astronauts return to Earth safely from China’s Tiangong-3 space station

9:49 am

After completing six months in space on China7s Tiangong-3 space station, three astronauts safely returned to Earth yesterday, with their Shenzhou capsule touching down in inner Mongolia.

This mission was the first full six month mission on the station. During their mission they completed four spacewalks. Though little was published about what was accomplished on those EVAs, it is likely it involved completing the construction of the station as well as installing some exterior experiments.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Russian communications satellite in trouble

9:41 am

A ten-year old Russian Ekspress geosynchronous communications satellite in early June developed problems that have forced engineers to shut down much of its capabilities.

The problem was similar to issues experienced in 2020 on a second similar Ekspress orbiting geosynchronous communications satellite, suggesting both satellites had the same design flaw.

For Russia the problem is made much more serious because its invasion of the Ukraine has made it impossible to replace this satellite.

The latest impact on Russian satellite communications capacity came at a time when the established production model for the Ekspress satellite family, relying on Western suppliers, had been disrupted by the Kremlin’s escalation of the war against Ukraine in 2022, likely resulting in severe delays if not a complete stop in the development of this type of spacecraft in Russia.

In other words, Russia has lost significant communications capacity, and does not have a way to replace that capacity because of the sanctions against it imposed because of its invasion. Once again, Putin’s idiotic war in the Ukraine has caused nothing but disaster for Russia.

SpaceX successfully launches cargo Dragon to ISS

9:25 am

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 launches 22 2nd generation Starlink satellites

6:19 pm

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.

The leaders in the 2023 launch race:

Avalanche to the east of Gale Crater on Mars

1:38 pm

Landslide on Mars
Click for original picture.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on February 19, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows an avalanche that slumped downward out of the material that forms the interior western wall of an unnamed 25-mile-wide crater about 100 miles east of Gale Crater, where Curiosity has been roving for more than a decade.

The scientists call these types of Martian avalanches “mass-wasting events”, since the entire mass of the cliff moves downhill in a chunk, rather than as a pile of rocks that grows in size and strength as it picks up material on its way down.

It is not clear how old this slide is. A lot of the material on this slope appears to be Martian dust, some of which has flowed into the avalanche material after it had slide downhill.

Shadowcam on South Korea’s Danuri lunar orbiter sees no obvious ice in the permanently shadowed interior of Spudis crater

10:30 am

Overview map

Using Shadowcam, a camera built by Arizona State University that is on South Korea’s Danuri lunar orbiter and is designed to see into very dark regions of little light, scientists have obtained optical images showing the permanently shadowed interior of Spudis Crater, located only about ten miles from the Moon’s south pole.

That picture is below. To the left is an annotated overview created from Lunar Reconnaissance Orbiter (LRO) high resolution images. The white box inside Spudis Crater indicates the area covered by the section of the Shadowcam image I have focused on. The red outlines indicate areas that are thought to be permanently shadowed. The relatively flat ridgeline between Shackleton and Spudis is one of the prime future landing sites for NASA’s Artemis program.

Newly discovered Starliner issues delay launch again

9:24 am

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!

Sunspot update: May activity once again far above prediction

5:06 pm

With the start of the month it is time once again for our monthly sunspot update, based on the new data that NOAA today added to its own monthly graph that tracks the number of sunspots on the Sun’s Earth-facing hemisphere. I have posted that graph below, but have added some extra details to provide some context.

In May the number of sunspots zipped upward again, ending up at the second highest monthly count during this ramp up to solar maximum, and the second highest count since the last solar maximum in 2014.

Martian rootless cones

1:02 pm

Rootless cones
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on March 8, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The camera team labeled this picture simply “Rootless Cones,” which is a feature that is created when the lava that covers the surface is thin, allowing the heated material below (which is not lava) to burst upward, producing the cone and caldera. If you look at the full image you will see other similar clusters of cones scattered about on this very flat and featureless plain. Apparently, the material that this lava plain covered had several similar bursts in a number of areas.

Such cones in this particular lava field are not rare, and in fact are evidence that this particular field is young.

Pushback: Christian adoption agency wins against NY’s attempt to force it to send kids to queer families

12:05 pm

New Hope: willing to fight for its religious beliefs
New Hope: willing to fight for its
religious beliefs

Bring a gun to a knife fight: When two different New York state agencies threatened to investigate and penalize the Christian nonprofit New Hope Family Services because it refused to place orphans with queer couples, instead insisting that the children under its care be adopted only by a mother and father, New Hope sued — twice — and has now won two settlements that will allow it to continue to place children in the manner that matches its beliefs.

Faith-based adoption provider New Hope Family Services secured a second victory against New York state officials, after securing a favorable settlement and a payment of $250,000 for attorneys’ fees in a related lawsuit settled last month. In settlement of the second lawsuit—which challenged an attempt by a different New York state agency to punish New Hope for adhering to its religious convictions—New York officials agreed to pay an additional $25,000 in attorneys’ fees and costs, and broadly confirmed New Hope’s right to continue its critical work of placing infants in permanent homes without government harassment.

ESA to live-stream image downloads from Mars Express

9:36 am

To celebrate Mars Express’s 20th year in orbit around Mars, the European Space Agency (ESA) has announced that tomorrow it will for one hour live-stream the image downloads coming from the orbiter.

I have embedded that live stream below. According to the press release, new images will arrive about once every 50 seconds. The camera that will be taking the pictures however is not one of Mars Express’s main instruments, but designed instead to simply monitor the separation of the Beagle-2 lander from the orbiter in 2003. Since 2007 however the science team has used its low resolution global images of Mars for public relations, education, and even some science research.

That the science team is not providing the live feed from its high resolution camera however illustrates why Mars Express gets so little press coverage, compared to Mars Reconnaissance Orbiter (MRO). All MRO images are released to the public, usually only a month or so after they reach Earth. The ESA however has never made the archive of Mars Express accessible, as far as I have been able to discover. All it does is periodically issue a press release about once every few months touting one new image, even though the spacecraft is taking dozens daily.

Viasat completes merger with Inmarsat

9:22 am

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 powers up its Dream Chaser mini-shuttle for the first time

9:09 am

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 Chaser’s 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.

Pushback: If the young are beginning to resist the leftist queer agenda, then there is real hope

12:01 pm

A little child shall lead them, by James Johnson
“A little child shall lead them,” painting by James L. Johnson.

And a little child shall lead them: There appears to be increasing evidence that it isn’t just the parents that are becoming aware and opposed to the queer and Marxist agenda that the public schools and leftist governments have been force feeding down children’s throats for the past decade. It now appears the students themselves are beginning to rise up in rebellion.

This story from May 29, 2023 illustrates the point:

Curiosity looks back again as it climbs higher onto Mount Sharp

10:02 am

Panorama
Click for full panorama.

Overview map
Click for interactive map.

After completing several weeks of drilling, Curiosity has once again started climbing the rocky rough slope of Mount Sharp in Gale Crater, working its way up into the giant slot canyon dubbed Gediz Vallis.

The panorama above, cropped, reduced, sharpened, and annotated to post here, was created from 31 pictures taken on May 30, 2023 by the rover’s right navigation camera. It looks back both at Curiosity’s past travels climbing Mount Sharp as well as the now increasingly distant floor and rim of Gale Crater. The rim is about 20-30 miles away.

On the overview map to the right, the blue dot marks Curiosity’s position when this panorama was taken, with the yellow lines indicating the approximate area covered. The white dotted line on both the panorama and map indicates the rover’s actual route, with the red dotted line its planned route.

Because of the steep rough terrain, the science team has shifted the rover a bit to the west as it climbs. It is going to be fascinating to watch how it manages this climb into Gediz Vallis, as it appears the terrain is going to get no less steep or rough.

North Korean rocket fails in attempt to put spy satellite into orbit

9:04 am

In North Korea’s first attempt today to place a spy satellite into orbit since 2016, the rocket failed shortly after launch, dropping into the ocean.

But the rocket lost thrust and plunged into the sea with its satellite payload, the official Korean Central News Agency reported. It added that authorities would investigate the “serious defects” revealed by the launch and conduct another test as soon as possible.

South Korea’s military said it had managed to locate and salvage a portion of the suspected debris. It released images showing a large barrel-like metal structure with thin pipes and wires at the bottom, which experts said might be a liquid fuel tank.

The U.S., Japan, and South Korea all condemned the launch as violating UN sanctions, as did the UN’s secretary-general.

The recovery by South Korea could yield a great deal of technical information about North Korea’s rocketry and missile program.

Russia delays launch of its Luna-25 mission one month to August

8:55 am


Click for interactive map.

Russia today announced that it is delaying the July launch of its Luna-25 mission to August.

No reason for the delay was revealed. The mission itself has been under development for almost a quarter century, with numerous delays. It will be the first lunar probe by Russia since the 1970s.

The lunar mission will be launched atop a Soyuz-2.1b carrier rocket with a Fregat booster from the Vostochny space center in the Russian Far East. Under the lunar project, the Luna-25 automatic station will be launched for studies in the area of the lunar south pole. The lander is set to touch down in the area of the Boguslawsky crater.

The green dot on the map shows this crater, with the white cross the Moon’s south pole. The other two missions are also targeting launches this summer, with Chandrayaan-3 set for a July launch and Nova-C in late September.

Spain becomes 25th nation to sign Artemis Accords

8:36 am

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.
