OSIRIS-REx does mid-course correction

8:36 am

To better refine its path back to Earth in order to properly aim its sample return capsule, engineers had OSIRIS-REx do a short successful 30 second engine burn on September 21, 2022.

Nor will this be the only course correction prior to sample return on September 24, 2023 in Utah.

To ensure a safe delivery, “Over the next year, we will gradually adjust the OSIRIS-REx trajectory to target the spacecraft closer to Earth,” said Daniel Wibben, trajectory-and-maneuver design lead with KinetX Inc. “We have to cross Earth’s orbit at the time that Earth will be at that same location.” Wibben works closely with the Lockheed Martin team in Littleton, Colorado, that flies the spacecraft.

Last month’s maneuver was the first time the OSIRIS-REx team changed the spacecraft’s trajectory since it left Bennu on May 10, 2021. Following this course adjustment, OSIRIS-REx would pass about 1,367 miles (2,200 kilometers) from Earth. A series of maneuvers beginning in July 2023 will bring OSIRIS-REx even closer, to 155 miles (250 kilometers) off the surface, close enough to release its sample capsule for a precision landing – via parachute at the Air Force’s Utah Test and Training Range in the Great Salt Lake Desert.

China launches military satellite

8:31 am

Using its Long March 2D rocket, China today successfully launched a satellite in its classified Yaogan series, suspected to be for military reconnaissance.

In fact, so little is known about the Yaogan satellites that we aren’t even sure how many were placed in orbit today. Normally a Yaogan launch puts three satellites into orbit (which is what this Space.com article assumes). The story from China’s state-run press above however does not say this at all. Instead, it implies that only one Yaogan satellite was launched.

Regardless, the leaders in the 2022 launch race:

47 SpaceX
45 China
14 Russia
8 Rocket Lab
7 ULA

American private enterprise still leads China 67 to 45 in the national rankings. It is now tied with the entire world combined 67 to 67. This launch today also brings the launch total this year to 134, which ties the record for the most successful launches in a single year, set last year. With two and a half months still to go, 2022 should end up breaking that record significantly.

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.

Two solar eclipses coming to the U.S. next year

12:47 pm

The next eclipses to cross the U.S.
Map by Michael Zeiler (GreatAmericanEclipse.com). Click for original.

The U.S. public will get to see two different solar eclipses during a six month period, starting one year from today.

The map to the right, cropped and reduced to post here, shows the dates and the path of both eclipses.

On 14 October 2023, anyone under clear skies within a path that sweeps from Oregon to Texas and then through parts of Central and South America will see an annular (“ring”) eclipse. Just six months later, on 8 April 2024, a total solar eclipse will sweep from Mexico to Texas to the Canadian Maritimes, plunging day into night and revealing the magnificent solar corona for anyone fortunate to be within the path of totality and under clear skies. Nearly everyone in North America will have a partial solar eclipse both days.

As always with eclipses, great care must be taken to watch it. With the 2017 eclipse Diane and I had good filters, but even so I noticed my eyes were very tired for several days afterward.

Pushback: Central Florida U forced to end censorship and blacklisting

12:31 pm

University of Central Florida: Hostile to free speech
University of Central Florida: Its hostility to free
speech had better change soon!

Bring a gun to a knife fight: In a settlement late last month [pdf] resulting from an April ruling against it by the courts, the University of Central Florida agreed to end its programs and policies designed to censor and even blacklist students who expressed opinions the university did not like.

The lawsuit [pdf] was brought by the legal organization Speech First, a student membership organization which acts to stop colleges from squelching the first amendment rights of students.

UCF officials agreed to pay $35,000 in legal fees, rewrite a harassment policy and discontinued the bias response team in a settlement with Speech First.

…The settlement “led to the elimination of UCF’s Stasi-like bias response team and ensured that the university’s policies actually consider the fundamental rights of their students,” Cherise Trump, the group’s executive director, wrote in a news release [pdf]. “Our win in the Eleventh Circuit not only set precedent in all of Florida, Alabama, and Georgia, but it also guarantees that universities recognize that the law is not on their side when they want to violate their students’ rights and shut down dissenting ideas.”

The college’s bias response teams were structured to report and punish any student for…

Perseverance spots Phobos

Phobos, as seen by Perseverance on Mars
Click for full image.

Cool image time! The photo to the right, cropped to post here, was taken on January 12, 2022 by one of the high resolution cameras on the Mars rover Perseverance, and shows the Martian moon Phobos.

As noted in an update today by Claire Newman, one of the members of the science team,

This provides a measurement, using visible light, of the amount of dust in the nighttime atmosphere, which can be compared to similar measurements made by looking at the sun during the daytime, and to nighttime measurements of dust abundance made in the infrared by MEDA [another Perseverance instrument].

There have been three attempts to land on Phobos, all by the Russians, all of which failed. At present a Japanese mission to Phobos, dubbed Mars Moons eXploration or MMX, is scheduled to launch in 2024. This is a planned sample return mission, and will also include a rover.

Lucy to fly past Earth on October 16th

10:13 am

Lucy solar panel graphic
Artist’s impression of solar panel

As part of its planned route to get to the Trojan asteroids in Jupiter’s orbit, the planetary probe Lucy is scheduled to fly only 220 miles above the Earth’s surface on October 16th.

Lucy will be passing the Earth at such a low altitude that the team had to include the effect of atmospheric drag when designing this flyby. Lucy’s large solar arrays increase this effect.

“In the original plan, Lucy was actually going to pass about 30 miles closer to the Earth,” says Rich Burns, Lucy project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “However, when it became clear that we might have to execute this flyby with one of the solar arrays unlatched, we chose to use a bit of our fuel reserves so that the spacecraft passes the Earth at a slightly higher altitude, reducing the disturbance from the atmospheric drag on the spacecraft’s solar arrays.”

That solar array remains unlatched (as shown in the graphic above), but because it is almost completely deployed and is producing about 90% of its intended electricity, engineers have ceased efforts to complete deployment and latching.

Skyrora’s first suborbital rocket launch fails shortly after liftoff

9:57 am

Capitalism in space: The first launch attempt of a suborbital rocket for Skyrora, a rocket startup from the United Kingdom, failed on October 8, 2022 shortly after liftoff.

The launch was from Iceland, with the rocket crashing in the ocean about 1,600 feet from the pad. No one was injured. The rocket, Skylark-L, was designed for a suborbital flight to test equipment that will be used in the orbital rocket, Skyrora-XL.

Skylark-L is Skyrora’s 11m suborbital rocket, capable of reaching 4x the speed of sound and an altitude of over 125 km. 70% of the technology tested in the Skylark-L launch attempt will be applied to the systems of the Skyrora-XL vehicle, providing a key incremental learning opportunity to increase technological readiness ahead of vertical orbital launch next year.

As this was an engineering flight, the failure is actually a good thing, as it will provide Skyrora’s engineers information about changes needed to make their rocket function properly. Don’t expect that first orbital launch however next year, as the company promises. These things always take longer than expected.

Watching return of ISS crew on Freedom

9:40 am

The SpaceX manned capsule Freedom has undocked from ISS, carrying three astronauts completing a six month mission, with a scheduled splashdown planned for 4:50 pm (Eastern) off the western coast of Florida.

I have embedded NASA’s live stream below, for those that wish to watch. Note that though NASA inserts itself into this event, once the spacecraft has left ISS everything — including all workers involved in splashdown operations — is solely under the supervision of SpaceX, with NASA’s participation only that of a customer, albeit a very powerful one. This is a capsule and splashdown designed, built, run, and most important, owned by a private American company, not the government.

Final decision: Arecibo will not be rebuilt

3:34 pm

The National Science Foundation has made it official: It will not rebuild the Arecibo Observatory in Puerto Rico, though it will fund the facility as an education center instead.

Now, the National Science Foundation (NSF), which owns the site, has determined that despite scientists’ pleas, Arecibo Observatory won’t be getting any new telescope to replace the loss. The new education project also doesn’t include any long-term funding for the instruments that remain operational at the observatory, including a 40-foot (12 m) radio dish and a lidar system.

…Instead, the NSF intends to build on the observatory’s legacy as a key educational institution in Puerto Rico by transforming the site into a hub for science, technology, engineering and math (STEM) education, due to open in 2023, according to a statement. The observatory is also home to the Ángel Ramos Foundation Science and Visitor Center, which opened in 1997.

It seems unclear how this education center will function. Will it be a school that students attend? Or simply a type of museum with a visitors center? This new plan appears to call for about $2 million per year in funding, which does not appear enough to do much of anything, other than to keep the lights on and hang some pretty astronomy pictures on the walls.

Changing slope streaks on Mars

Overview map

Changing slope streaks on Mars
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on July 20, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists have labeled a “Splitting Slope Streak” on a mound/hill near the equator and located almost midpoint between the giant volcano Olympus Mons about 2,000 miles to the east and the almost as big volcano Elysium Mons about 2,500 miles to the west. The white cross on the overview map above marks this location, north of the Medusae Fossae volcanic ash deposit.

The slope streak in question is the biggest and darkest at about 7 o’clock. Slope streaks are a feature unique to Mars that remain as yet unexplained. They are not ordinary avalanches, despite their appearance. They seem to have no effect on the topography, and thus are more a stain on the surface. Moreover, some are bright, some dark, and all happen randomly and fade with time. Some think they may be brine-related, while others link them to dust. No theory explains them completely.

What makes this slope streak interesting is that it is relatively new. Compare it with the picture taken in 2016 below.

Pushback: Chants of “Vote them out!” overwhelm school board meeting

12:11 pm

Roxanne McDonald thinking she is in charge.
School board president Roxanne McDonald,
thinking she is in charge.

Bring a gun to a knife fight: A school board meeting in Dearborn, Michigan, had to be shut down when a mostly Muslim crowd of parents (with some Christians as well) became outraged by what appeared to be resistance by the school board to their demand that various books advocating the queer agenda be removed from the public school libraries.

As the meeting progressed, interruptions from the crowd became louder and increasingly frequent, despite calls from board members for decorum and respecting the right of others to speak.

Chants of “vote them out,” broke out when school board president Roxanne McDonald said a three-minute limit per speaker would be strictly enforced. The room was also far over its occupancy limit, and after the crowd ignored multiple orders for people to move into two overflow rooms, board members ended the meeting prior to the public comment period.

The video below shows the situation leading up to the board shutting down the meeting. Watch it and tell me if you do not think board president Roxanne McDonald is a self-righteous petty dictator who has utter contempt for the parents who are there.

The known near Earth asteroid catalog now tops 30,000

9:35 am

Chart of NEA's discovered over time

The catalog of known near Earth asteroids that have been identified using a number of survey telescopes in space and on the Earth now totals 30,039. As defined at the link:

An asteroid is called a near-Earth asteroid (NEA) when its trajectory brings it within 1.3 Astronomical Units (au) of the Sun. 1 au is the distance between the Sun and Earth, and so NEAs can come within at least 0.3 au, 45 million km, of our planet’s orbit.

Currently, near-Earth asteroids make up about a third of the roughly one million asteroids discovered so far in the Solar System. Most of them reside in the asteroid belt between Jupiter and Mars.

NEAs are also called NEOs (Near Earth Objects). The chart above, produced by the Center for NEO Studies which tracks these objects, shows the number of NEAs discovered over time.

Of the 30,039 now known, about 1,400 have orbits with “a non-zero” chance of hitting the Earth. None however will do so in the next hundred years at least.

Though the pace of discovery is vastly improving — as indicated by the steep rise in the curve in the graph — only when that curve begins to flatten out will we know that we are getting close to having a more-or-less complete survey of these objects.

TESS enters safe mode

9:18 am

The science team for TESS (Transiting Exoplanet Survey Satellite) revealed yesterday that the spacecraft had entered safe mode on October 10th.

The spacecraft is in a stable configuration that suspends science observations. Preliminary investigation revealed that the TESS flight computer experienced a reset. The TESS operations team reported that science data not yet sent to the ground appears to be safely stored on the satellite. Recovery procedures and investigations are underway to resume normal operations, which could take several days.

TESS has been in orbit since 2018, where it has been repeatedly taking survey images of the entire sky. Astronomers then compare these images to see if they can spot exoplanet transits (as well as any other new phenomenon). So far 250 exoplanets have been identified.

Ispace targets November 9-15 launch window for first commercial lunar lander

9:07 am

The private Japanese company Ispace has now scheduled the launch of its commercial lunar lander Hakuto-R on a SpaceX Falcon 9 rocket for a November 9-15, 2022 launch window.

Though the lander’s primary goal is to see if this lander will work, it also includes several customer payloads, the most significant of which is the Rashid rover from the United Arab Emirates. Rashid, which is about the size of a Radio Flyer red wagon, will operate for one lunar day, about two weeks. While its main mission is to test the engineering and to train the engineers who built it, it will have two cameras for taking pictures. In addition, on its wheels are test adhesive patches of different materials, designed to see how each material interacts with the Moon’s abrasive dust.

An icy hollow on Mars

2:07 pm

A icy hollow on Mars
Click for full image.

Cool image time! The photo to the right, cropped, reduced, and enhanced to post here, was taken on August 20, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a somewhat typical example of the many ice scarps that scientists have identified in MRO pictures.

Though this is not a hard fast rule, most of the ice scarps so far found tend to have the steep cliff on the pole-facing side, with the scarp very slowly retreating towards the equator. In today’s example, the scarp where an ice layer in the cliff wall has been identified is indicated by the white arrow, though three sides of the hollow, on the east, north, and west sides, could all also have exposed ice.

Nor is that the only likely ice at this location at 56 degrees south latitude. The stippled plain surrounding the hollow clearly looks like an eroded ice layer, likely covered with a thin protective coat of dust to protect if from quickly sublimating away. The dark streaks across this surface are likely dust devil tracks.

As documented by the global map below, Mars is like Antarctica, a desert with water ice everywhere.

Pushback: Teacher suspended for not submitting to queer agenda immediately reinstated when hundreds protest at board meeting

12:16 pm

Total victory

Bring a gun to a knife fight: This story begins in late September when the South Side Area School District in Pennsylvania decided it and all its teachers must comply with the insane queer agenda. According to the new policy, outlined in a letter, all of its teachers were ordered to use the pronouns that any student demanded of them. To the district, it didn’t matter if the student was eight or eighteen, if any student on a whim wanted to identify as a boy, then a girl, or then maybe even a tiger, the teachers were required to comply.

Daren Cusato, a biology teacher in the district for 30 years, refused. He sent a letter back to the district, explaining this violated both his Christian beliefs and his first amendment rights.

“Love the sinner but hate the sin,” said RJ Cusato, Daren’s son. “We don’t support what they’re doing but still love the person. He doesn’t have any problem with the students. We have no problems with the kids at all, he just doesn’t want to support what they’re doing. He doesn’t want to give them a pat on the back if they’re doing something he doesn’t think is right.”

The district’s response was immediate.

Dennis Tito signs deal to fly on 2nd manned Starship mission around Moon

10:26 am

Capitalism in space: Dennis Tito, the first tourist to fly in space and now 82-years-old, has signed a deal with SpaceX for both him and his wife Akiko to fly on 2nd manned Starship mission around Moon.

His weeklong moonshot — its date to be determined and years in the future — will bring him within 125 miles (200 kilometers) of the lunar far side. He’ll have company: his wife, Akiko, and 10 others willing to shell out big bucks for the ride.

Tito won’t say how much he’s paying; his Russian station flight cost $20 million.

The couple recognize there’s a lot of testing and development still ahead for Starship, a shiny, bullet-shaped behemoth that’s yet to even attempt to reach space. “We have to keep healthy for as many years as it’s going to take for SpaceX to complete this vehicle,” Tito said in an interview this week with The Associated Press. “I might be sitting in a rocking chair, not doing any good exercise, if it wasn’t for this mission.”

The bottom line is that this deal, combined with the two other passenger Starship deals SpaceX has already signed, demonstrates that there is a solid market for Starship, even before its first launch. Expect that market to boom once the rocket begins operations.

Will Tom Cruise ever actually shoot a movie in space?

10:17 am

Capitalism in space: According an interview last week from Donna Langley, chairman of Universal Film Entertainment Group, the company is arranging for Tom Cruise to film scenes of a movie on ISS, where Cruise will also be the first non-professional to do a spacewalk.

“That’s the plan. We have a great project in development with Tom that does contemplate him doing just that,” she said, “taking a rocket up to the space station and shooting and hopefully being the first civilian to do a spacewalk outside of the space station.”

She said the film request came from Cruise directly and that he is in close collaboration with director Doug Liman, who previously worked with Cruise in 2014’s “Edge of Tomorrow” and is also known for “The Bourne Identity” franchise, “Mr. and Mrs. Smith” and “Jumper.”

This claim might be true, but producers associated with Cruise have been making such claims now for three years, none of which have come even close to happening. I am sure the project is being discussed, and even pushed hard, but based on what has actually happened, this announcement could simply be a way to generate buzz for Cruise’s next film, whether or not he flies.

Nonetheless, I fully believe that Cruise is the source of this idea, and wants to do it, given his habit of doing his own stunts in his movies.

Shells of dust surrounding massive binary star

10:07 am

Webb infrared image of dust shells surrounding binary star system
Click for full image.

Cool image time! Using the Webb telescope, astronomers have detected a series of concentric shells surrounding the massive binary star dubbed Wolf-Rayet 140.

The infrared image to the right shows these shells quite clearly. As noted by astronomer Ryan Lau:

“On the night that my team’s Early Release Science observations of the dust-forming massive binary star Wolf-Rayet (WR) 140 were taken, I was puzzled by what I saw in the preview images from the Mid-Infrared Instrument (MIRI). There seemed to be a strange-looking diffraction pattern, and I worried that it was a visual effect created by the stars’ extreme brightness. However, as soon as I downloaded the final data I realized that I was not looking at a diffraction pattern, but instead rings of dust surrounding WR 140 – at least 17 of them.

“I was amazed. Although they resemble rings in the image, the true 3D geometry of those semi-circular features is better described as a shell. The shells of dust are formed each time the stars reach a point in their orbit where they are closest to each other and their stellar winds interact. The even spacing between the shells indicates that dust formation events are occurring like clockwork, once in each eight-year orbit. In this case, the 17 shells can be counted like tree rings, showing more than 130 years of dust formation. Our confidence in this interpretation of the image was strengthened by comparing our findings to the geometric dust models by Yinuo Han, a doctoral student at the University of Cambridge, which showed a near-perfect match to our observations.

Furthermore, the spectroscopy from Webb says these dust shells are carbon-enriched, showing that the dust released by these aged massive stars is a significant source of the carbon in the universe, the fundamental atom needed for life.
