A new plan to send a probe to interstellar object Oumuamua

9:55 am

Project Lyra about to rendezvous with Oumuamua
Click to watch the animation.

Scientists have proposed a project to send an unmanned probe to Oumuamua, using the Earth, Jupiter, and then the Sun to slingshot onto a path that would catch up with the interstellar object on its journey leaving the solar system in the mid-2050s.

The project, dubbed Lyra, was first proposed in 2023. The scientists have now revised the plan to account for the greater speeds needed to catch up with Oumuamua as it continues to move away from us. It is still within the solar system, but it is moving away very fast.

The graphic to the right, a screen capture of an animation at the link, shows the spacecraft as it finally approaches the interstellar object in 2055. To get there it would launch in the early 2030s, slingshot past the Earth to reach Jupiter, which would then slow it down so that it would fall back to the Sun, passing it by less than 450,000 miles, which would slingshot it out to Oumuamua (with the help of an additional engine burn). To survive the close solar approach it would use the same technology used by the Parker Solar Probe, which has already successfully flown that close to the Sun.

It seems this is an entirely worthwhile project, since Oumuamua continues to baffle scientists as to its nature. While most belief it is a natural but very unusual interstellar asteroid, none can dismiss the possibility that it instead an alien spacecraft. The data precludes nothing. Getting close to it seems worthwhile, no matter what.

For me, that rendezvous will happen when I would be 102 years old. I don’t think I’ll be here to see it.

Japan’s H2A rocket launches military surveillance satellite

9:24 am

Japan’s H2A rocket today successfully launched a new military surveillance satellite designed to observe North Korean’s missile launch sites.

The live stream of the launch is here, cued to T-10 seconds.

New reports had previously reported the last launch of the H2A occurred in September 2023, launching Japan’s SLIM lunar lander and XRISM X-ray telescope. This was obviously incorrect. Today’s launch appears to close out the H2A manifest, leaving Japan rocketless until it can get both its new H3 and grounded Epsilon rockets operational.

Boeing completes Starliner parachute drop test

9:13 am

Boeing on January 9, 2023 successfully completed a parachute drop test of its Starliner capsule, testing whether the redesigned connection between the chutes and the capsule was now meeting proper safety specifications.

The drop test, which used a Starliner parachute system attached to a dart-shaped sled the same weight as a Starliner, was performed to confirm the functioning of a redesigned and strengthened soft link joint that is part of the network of lines connecting the parachutes to the spacecraft. The test also validated a change to strengthen one textile joint in the parachute, increasing overall parachute robustness. As with other capsules, Starliner relies on parachutes to land safely when it returns to Earth.

Engineers are still analyzing the results, though the parachutes worked as planned. The first manned mission of Boeing’s commercial capsule is now scheduled for April 2024, only four years late as well as four years after SpaceX accomplished the same thing. It still remains staggering that the company did not find out about that soft link joint when it was designing the capsule, instead of only months before the first manned mission last year. It is not as if the use of parachutes to land capsules is cutting edge technology.

Dave Brubeck Quartet – Golden Brown

6:01 pm

An evening pause: This video is not what it seems. The sax player, Lawrence Mason, has created a cover of this Dave Brubeck song by editing and playing over the Dave Brubeck quartet playing another song in 1965. As he notes on the youtube page, he did it as a tribute to “Paul Desmond (saxophonist with the Dave Brubeck quartet – the anniversary of his death is at the end of this month) [May 2020].”

Double-ringed crater near the Starship landing zone on Mars

2:41 pm

Double-ringed crater
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on September 10, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label simply as a “double-rim crater.”

If you look close you might not be unreasonable to call this instead a triple-rim crater, as there appear to be two rings on each side of the highest crater rim.

Multple rings in craters are not rare. We see many on the Moon. Most however are associated with very large impacts, and are an expression of the ripples formed at impact, not unlike the ripples seen when you drop a pebble in water. Unlike water ripples, the ripples formed in rock are impact melt that quickly refreezes, thus capturing those ripples as concentric rings.

In this case, these rings likely signal not freezing rock but freezing ice.

Fauci: Now an admitted liar as well as incompetent scientist

12:47 pm

Fauci: Washington's top liar
Anthony Fauci: the liar-in-chief during
the Wuhan panic

This week Anthony Fauci was brought before a committee in the House of Representatives for closed-door hearings on his actions during the COVID epidemic in 2020-2021. Though supposedly private, the committee has been providing detailed recaps of Fauci’s testimony.

What it has learned is that Fauci was not only a chronic liar during his time as director of the National Institute of Allergy and Infectious Diseases (NIAID), he was also utterly incompetent as both a scientist as well as an administrator.

None of this really is news. As early as December 2020 Fauci admitted publicly that he had purposely misstated facts and scientific data for political reasons. Repeatedly I have reported many other examples of his dishonesty and incompetence (see for example these posts from June ’21, April ’22, September ’22, November ’22, and September ’23).

Nonetheless, Fauci’s testimony now is worth reviewing, because it underlines starkly how he misled and misinformed the public, causing great harm for no gain.

First, he admitted in testimony that the demands by him and the government that everyone maintain a six-foot distance during the epidemic was utter garbage, based on no scientific data at all.

In Tuesday’s session, Fauci admitted that the six-foot social distancing recommendation “was likely not based on any data,” according to the committee. “It just sort of appeared,” it wrote, quoting Fauci.

In August 2020 I found evidence suggesting the only source for this absurd rule came from a high school science project. Fauci has now essentially confirmed this, admitting that there is no legitimate science behind the six-foot rule.

Webb infrared data detects unexpected structure inside debris disk of Beta Pictoris

10:36 am

Beta Pictoris debris disk
Click for original image.

A new false color infrared image from the Webb Space Telescope has revealed an unexpected structure extending out from the two debris disks that surround the near-by star Beta Pictoris, with computer modeling suggesting might this structure have been the result of a large collision as recently as only 100 years ago.

That false-colr image is the right, with this newly discovered structure, described by the scientists as resembling “a cat’s tail”, on the right side. The infrared light of the star has been blocked in the center in order to see the details of the disk.

Webb’s mid-infrared data also revealed differences in temperature between Beta Pic’s two disks, which likely is due to differences in composition. “We didn’t expect Webb to reveal that there are two different types of material around Beta Pic, but MIRI clearly showed us that the material of the secondary disk and cat’s tail is hotter than the main disk,” said Christopher Stark, a co-author of the study at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The dust that forms that disk and tail must be very dark, so we don’t easily see it at visible wavelengths — but in the mid-infrared, it’s glowing.”

To explain the hotter temperature, the team deduced that the dust may be highly porous “organic refractory material,” similar to the matter found on the surfaces of comets and asteroids in our solar system. For example, a preliminary analysis of material sampled from asteroid Bennu by NASA’s OSIRIS-REx mission found it to be very dark and carbon-rich, much like what MIRI detected at Beta Pic.

In an attempt to explain the cat’s tail, the scientists used computer models, which suggested it might have been caused by an event that produced a lot of dust, such as a collision between two large objects in the debris disk, and that event could have happened as recently as a hundred years ago.

This hypothesis remains unconfirmed, with much more data required before a final explanation can be accepted.

Astronomers discover Earth-sized exoplanet roasted by a Sunlike star

10:18 am

Using data from the TESS space telescope, astronomers have discovered an Earth-sized exoplanet in a 4.2 day orbit around a G-type star like our Sun about 70 light years away.

The tidally locked planet is very close to Earth size (it is approximately 1.1 times the diameter of our own planet) and it’s orbiting a star that’s similar to the size of our Sun (the star is about 0.91 the size and 0.99 the mass of the Sun).

The star in this system is a G-type star, the same type as our Sun. But HD 63433 d orbits much closer to its star than we do, with a minuscule 4.2 day long “year” and extremely high temperatures on its dayside.

To read the research paper, go here. At an estimated age of only 400 million years, this exoplanet and its solar system of at least two other planets is much younger than the 4.5-billion-year-old Earth. Though the press release and paper note the possibility that it is similar in many ways to Io, a volcanic planet covered with lava, we don’t know this. All we know is that it is roasted by its star by orbiting so close to it.

Blue Origin moves first stage of its New Glenn rocket from factory to launchpad hanger

10:08 am

In what might be the first step in assemblying Blue Origin’s New Glenn rocket for the first time (followed by a launch), the company yesterday transported the rocket’s first stage from its factory to its launchpad hanger.

Transported by a series of multiwheeled carriages and an arching structure, the 189-foot-tall first stage for what will be a 320-foot-tall rocket when fully assembled traveled horizontally on a 22-mile trip from the New Glenn factory in Merritt Island through Kennedy Space Center over to Cape Canaveral Space Force Station where Blue Origin has a hangar and launch pad at Launch Complex 36.

Jeff Bezos has said the company plans that first launch before the end of this year, though the company has been making this same promise now for the last three years, and is years behind schedule. What makes this promise different however is that this time we are seeing actual hardware moving towards the launchpad.

The article also gives a rough update on the company’s effort to manufacture the many BE-4 rocket engines needed for New Glenn (7) and ULA’s Vulcan rocket (2). The two engines for the next Vulcan launch in April are presently undergoing final testing at Blue Origin’s test facility in Texas, and the company says it is about to ramp up production. It thus appears that getting enough engines built is still the main obstacle to launch. We shall finally know later this year if Blue Origin has solved this problem.

Update on Astrobotic’s Peregrine lunar lander

9:56 am

The expected flight path of Peregrine
Click for original image.

The company Astrobotic has released several more updates on the status of its Peregrine lunar lander, which will no longer attempt a lunar landing because of a major fuel leak.

The map to the right shows its expected path in the coming days. While sent in a very elongated Earth orbit by ULA’s Vulcan rocket, the spacecraft was unable to do the additional engine burns that would have put it on the correct path to reach the Moon. Instead, it will fall back towards Earth, though its fate beyond that is unclear at this time.

Meanwhile, engineers have succeeded in getting data from all payloads designed to communicate back to Earth.

We have successfully received data from all 9 payloads designed to communicate with the lander. All 10 payloads requiring power have received it, while the remaining 10 payloads aboard the spacecraft are passive. These payloads have now been able to prove operational capability in space and payload teams are analyzing the impact of this development now.

Engineers have also been able to get the spacecraft to send back a number of images. These successes help the company prove out some of the spacecraft’s systems, though it is unable to test the mission’s prime goal, landing on the Moon.

China successfully launched twice today

9:43 am

China completed two different launches from two different launch locations today, with one being the first launch of a new rocket.

First, China’s solid-fueled Kuaizhou-1A lifted off from the Jiuquan spaceport in northwest China, placing what the state-run press described as a “satellite is mainly used for experiments such as space environment detection.” No other information was released. Nor was any information released about where the rocket’s lower stages crashed inside China.

Next, a Chinese pseudo-company, Orienspace, completed the first launch of its new Gravity-1 rocket, lifting off from a barge off the coast of Haiyang in the Yellow Sea carrying three satellites. The state-run press once again failed to mention this company’s name in its report, describing it instead as a “launch by China”, illustrating again the lack of independence these pseudo-companies have. They might design and build on their own, but they are controlled entirely by the communist government, and at any time can be taken over by it.

Though the rocket itself appears very similar in many ways to India’s largest version of its liquid-fueled GSLV rocket, very squat with four strap-on boosters, Gravity-1 is solid-fueled (thus derived from the missile technology controlled by China’s military). It is also the most powerful solid-fueled rocket now in operation, twice as powerful as Europe’s Vega-C.

Engineers succeed in releasing two fasteners that blocked access to OSIRIS-REx Bennu samples

9:22 am

Using new specially designed tools, engineers have finally succeeded in removing the two fasteners that had prevented them from opening the sample return capsule that holds the bulk of material from the asteroid Bennu that was grabbed by OSIRIS-REx and brought back to Earth.

Curation processors paused disassembly of the TAGSAM head hardware in mid-October after they discovered that two of the 35 fasteners could not be removed with the tools approved for use inside the OSIRIS-REx glovebox.

In response, two new multi-part tools were designed and fabricated to support further disassembly of the TAGSAM head. These tools include newly custom-fabricated bits made from a specific grade of surgical, non-magnetic stainless steel; the hardest metal approved for use in the pristine curation gloveboxes.

The fasterners have been removed, but the sample capsule still needs to be dissassembled before the samples can be accessed and analyzed. It is now expected that by the spring the material will be fully catelogued and available for scientists to study.

In an ironic twist, OSIRIS-REx brought back so much extra material clinging to the outside of that sample return capsule that such research has already begun. In fact, that extra material actually exceeded in weight the minimum amount the mission wanted to capture inside the capsule. What will be found inside the capsule will only add to the mission’s success.
