More direct images released of exoplanet 87.5 light years away

Keck images of exoplanet over time

The Keck Observatory in Hawaii has now released its own image of the exoplanet AF Leporis b, following up the images produced by the Very Large Telescope (VLT) released in February.

The direct images Franson’s team captured revealed that AF Lep b is about three times the mass of Jupiter and orbits AF Leporis, a young Sun-like star about 87.5 light-years away. They took a series of deep images of the planet starting in December 2021; two other teams also captured images of the same planet since then.

What make the Keck observations most interesting is that they captured over time the motion of the exoplanet as it orbited its star. The two images to the right show this motion.

The paper, available here, was published today in Astrophysical Journal Letters. This particular star also has a debris disk surrounding it, suggesting it is a young solar system still in the process of forming. From the paper’s conclusion:

AF Lep joins other young planet hosts with debris disks such as β Pic, HR 8799, HD 206893, and HD 95086, reinforcing indications of a higher frequency of long-period planets orbiting stars hosting debris disks.

Startup orbital tug company experiences technical issues on demo flight

9:36 am

The first test rendezvous and docking of two smallsats built by the startup orbital tug company Starfish Space and space station startup Launcher/Vast are facing significant technical issues because both spacecraft are spinning in an unexpected manner.

Soon after Orbiter SN3 separated from the Falcon 9 upper stage, it experienced an anomaly that set it spinning at a rate on the order of one revolution per second, far outside the bounds of normal operating conditions.

By the time Launcher’s team made contact with Orbiter, fuel and power levels were critically low — and the team made an emergency decision to deploy Otter Pup immediately. In a joint statement issued today, Launcher and Starfish Space said that quick action “gave the Otter Pup mission a chance to continue.”

With assistance from Astro Digital and ground station partners, Starfish’s team contacted Otter Pup and determined that it was generating power — but was also spinning because of the circumstances of its emergency deployment.

The plan had been to deploy Otter Pup and have it rendezvous and then dock with Orbiter, demonstrating the maneuverability of both spacecraft as well as their docking equipment. The spinning now threatens the company’s ability to do this. Over the next few months engineers will make attempts to slow the spinning of Orbiter, but it is unlikely a docking can now be attempted.

Intelsat and SES end negotiations to merge

9:27 am

In a very short press release, the Luxembourg-based satellite company SES today announced that it has broken off negotiations to merge with the satellite company Intelsat. The full text:

SES announces today that discussions regarding a possible combination with Intelsat have ceased. On 29 March 2023, SES had confirmed that the company engaged in discussions with Intelsat and that there could be no certainty that a transaction would materialise.

It appears the two companies could not settle differences on a number of points, and according to this article Intelsat decided to end negotiations yesterday.

There has been a trend among the established satellite companies to consolidate and merge, faced with the stiff competition from the new satellite constellations of Starlink and OneWeb. It is very possible that both of these companies will either revisit the idea of this merger, or begin negotiations with other established satellite companies.

Ecuador becomes 26th nation to sign Artemis Accords

9:20 am

In a ceremony yesterday in Washington, Ecuador became the 26th 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, Ecuador, 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.

Adding third world nations to the alliance strengthens it, but it is really the clout of major space players like France, Luxembourg, the UK, the UAE, Italy, and Japan that gives the United States a great deal of leverage in establishing future space legal policy, assuming the alliance is used as originally intended. Considering however the Biden administration’s general hostility to the private sector and freedom, it is unclear if that will be the goal.

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.

ULA launches Delta-4 Heavy rocket on next-to-last flight

9:02 am

Early this morning ULA successfully place a National Reconnaissance Office classified surveillance satellite into orbit, using its Delta-4 Heavy rocket lifting off from Cape Canaveral.

This was ULA’s its first launch in 2023. At the start of the year, the company’s manifest listed ten launches. Whether is can complete that manifest in the remaining six months is questionable, considering it has rarely managed a launch pace exceeding one launch per month in its entire history.

This launch was also the next-to-last for the Delta-4 Heavy. ULA is retiring that rocket and replacing it with the still-not-flown Vulcan rocket. The plan had been for there to be an overlap in use as one was retired and the other was initiated. That has not happened.

The leaders in the 2023 launch race remain the same:

42 SpaceX
24 China
8 Russia
5 Rocket Lab

American private enterprise now leads China in successful launches 48 to 24 in the national rankings, and the entire world combined 48 to 40, with SpaceX by itself still leading the rest of the world, excluding other American companies, 42 to 40.

Greta Thunberg: All humanity is now extinct on Earth, because we didn’t do anything about global warming

12:40 pm

Greta Thunberg speaks!
Greta Thunberg speaks!

How dare you! On June 21, 2018, Greta Thunberg informed us — as shown in her tweet to the right — that we only had five years left to stop using fossil fuels, and if we didn’t “climate change will wipe out all of humanity.”

I am hardly the only person to note this example of global warming fraudulence. Numerous reporters have also gleefully noted it, with this essay today at American Thinker by Andrea Widburg probably the most damning, not so much for noting the ignorant rantings of this uneducated high school drop-out whom the left made their icon of knowledge and top global warming expert, but for the list she provides of the endless number of other failed doomsday predictions by global warming activists and politicians.

That list was compiled in 2019, and thus it did not yet include Thunberg’s absurd prediction. Nor did it include the endless string of additional false doomsday predictions that this crowd has continued to issue in the years since, all of which I guarantee without any uncertainty will all fail, just as their hundreds of past doomsday predictions have failed.

You see, the point of those predictions was not to educate, but to instill fear, so as to then justify a power grab by the government. As Widburg concludes:

A lava flow on a Martian lava plain

12:04 pm

A lava flow on a Martian lava plain
Click for original image.

While much of surface of the Martian equatorial regions is comprised of volcanic flood lava, the place where it is most obvious and evident is on the flanks of the three giant volcanoes of the Tharsis Bulge. Here, lava did not simple spout from surface vents to flood low-lying large areas, filling those depressions quickly almost like water. Instead it issued from vents on the slopes of those mountains, or from their calderas at their peaks, and flowed downhill almost like tsunamis of magma.

The picture to the right, rotated, cropped, reduced, and sharpened to post here, is a great example. Taken on March 11, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), it shows the foot of one such flow, frozen in place as it oozed down hill from the Arsia Mons, about 300 miles away to the northwest.

Two new European rocket startups sign deal with France to launch from French Guiana

11:28 am

The French space agency CNES today signed agreements with two different European smallsat rocket startups, Spain’s PLD Space and Germany’s Rocket Factory Augsburg (RFA), allowing each to launch from France’s old launchpad in French Guiana that was used in the 1970s by its long abandoned Diamant rocket.

From the RFA press release:

Until now, the launch pad in Kourou has only been used by CNES for its Diamant rocket in the 1970s. Now the launch complex is to be given a new purpose, in the tradition of opening access to space through innovative and groundbreaking ventures. As such, RFA is one of the first NewSpace companies to be given the opportunity to use it. The new launch pad will be upgraded and equipped in the coming years with the aim of being used for launches from 2025.

These agreements are part of a slew that have come out of Europe in the past year or so that all indicate that the European Space Agency (ESA) and its partners have finally abandoned any attempts to build rockets, and are instead looking to private enterprise to do it for them. First Germany encouraged private rocket startups, independent of Arianespace and ESA. Then Spain followed with PLD Space. Then Arianespace, the commercial arm of ESA that for decades built all rockets for ESA, announced it was making agreements with these startups to have them launch payloads instead.

These new deals today indicate that France has now joined the rush to private enterprise, which is a very significant development as France as always been the leader in having ESA build its own rockets through Arianespace. It appears it is now looking away from government-run space.

All these actions are also suggest a dim future for ArianeGoup’s Ariane-6 rocket, built under the old system but with an attempt to give private enterprise more power, with ArianeGroup, not Arianespace, owning and controlling it. Its design however was dictated largely by ESA, thus resulting in a rocket that is too expensive and therefore not competitive.

The long term result will be greater competition, both in Europe and worldwide, which in turn is going to fuel a renaissance in rocket development, which in turn is going to speed the exploration and colonization of the rest of the solar system.
