Arianespace successfully completes first Ariane 5 launch in almost a year

11:23 pm

Arianespace today successfully completed its first Ariane 5 launch since August 2020, placing in orbit two commercial communications satellites.

The long gap in launches occurred because of a vibration issue discovered during that August 2020 launch durng the release of the rocket’s two fairing halves.

Engineers introduced modifications to the Ariane 5’s payload fairing, or nose cone, to reduce vibrations imparted on the satellites during separation of the shroud, which protects payloads during the first few minutes of flight through the atmosphere. Ground teams will analyze data from the rocket to make sure the changes reduced the vibrations.

Another launch is scheduled for September, followed next by the launch of the James Webb Space Telescope in either November or December. The results from today’s launch as well as the one in September will determine if the Webb launch will go forward on time.

These issues with Ariane 5, delays imposed by the company in fear of the Wuhan flu, and other launch problems with Arianespace’s Vega rocket, has meant that this is only its second launch in 2021, a pace that is below its pace for most of the last decade. Whether the company can recover and pick up the pace before the end of the year will depend on what they learn during today’s launch.

With only two launches total, Europe’s Arianespace remains off the leader board in the 2021 launch race:

24 China
20 SpaceX
12 Russia
3 Northrop Grumman
3 Rocket Lab

The U.S. lead over China in the national rankings remains 30 to 24.

Peter, Paul and Mary – Don’t Ever Take Away My Freedom

6:01 pm

An evening pause: A nice intro to the weekend as well as a fitting closing to my July fund-raising campaign. Strangely, there are no live performances of this song by Peter, Paul, & Mary available on the web. Could it be that they themselves became uncomfortable with its sentiments in later years, being hardcore leftists? I wonder. Consider the lyrics:

[Third verse]
Now when I’m old and thinking over the life that I’ve led
If there’s one final wish left to me
I will pray for the children yet to be born
I will pray that they will always live free

[Chorus]
Don’t ever take away their freedom
Don’t ever take it away
Let us cherish and keep that one part of our lives
And the rest we’re gonna find one of these days

These are not the sentiments of most leftists today. The last thing they want is freedom for all. What they want now are mandates, edicts, rules, regulations, and a boot smashing the face of all humans, forever, in the guise of a muzzle.

Note also that the song opens with Home on the Range, which is how PP&M originally recorded for their album, Peter, Paul, & Mommy Two.

Today’s blacklisted American: Town tries to silence Trump supporter; he sues

2:05 pm

Banned for being conservative
No first amendment rights in Long Beach, New York!

The modern dark age: Because the town of Long Beach, New York has forced a Trump supporter to hide his car, festooned with pro-Trump and conservative messages, he is suing that town for $25 million for denying him is first amendment rights.

“I believe the city is trying to silence me because I’m pro-Trump,” [Michael Wasserman] told The Post. The 62-year-old entrepreneur has become known in the area for plastering his home — along with his Porsche and Jeep — with a rotating variety of political flags and stickers.

Now he has filed a $25 million federal suit — against the City of Long Beach, the chief of police, the city manager and specific police officers — after officials forced him to remove the flags on his cars.

The town claims they are a violation of an ordinance stating that “[No] sign shall be erected, affixed or maintained within the perimeter of any … public street or public property.” Wasserman parks his car on a public street outside his home.

“They’re bending and massaging the ordinance to fit the crime,” Wasserman told The Post. “This is a blatant attempt to silence me.”

The picture above shows Wasserman leaning on his car, with his home behind him, also covered with flags and political banners.

The city claims they are simply enforcing a law that forbids signage without permission on public streets. Yet, how are the signs on Wasserman’s car any different then every bumper sticker you see? They are not, and this is where Wasserman’s claim that it is pure political oppression seems confirmed.

Wasserman’s case is further reinforced by the treatment he gets generally in this blue-state New York town:

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.

Apollo: When Americans last did some real exploring

1:02 pm

The journey of Apollo 15 on the Moon
Click for full image.

Today is the fiftieth anniversary of the landing of Apollo 15 on the Moon. To commemorate that event the science team for Lunar Reconnaissance Orbiter (LRO) today published some orbital images that capture the astronauts’ travels while on the Moon. The picture to the right, reduced to post here, outlines in oblique view their various excusions to the edge of Hadley Rille and the foot of a mountain dubbed Hadley Delta. As they note,

While Apollo 15 was the fourth mission to land a crew successfully on the lunar surface, it still pioneered many new technologies and had many firsts.

Some of the technologies developed for Apollo 15 included new suits, which were more flexible and had longer life support capabilities, as well as the Lunar Roving Vehicle (LRV), a rover capable of speeds up to 15 km / hour. With these advancements, astronauts Commander David (Dave) Scott and Lunar Module Pilot James (Jim) Irwin were able to travel more than eight times the distance traveled during the previous mission, for a total of over 25 km.

All told, astronauts Dave Scott and Jim Irwin spent more than 18 hours exploring the lunar surface on three scouting trips, covering 15.5 miles. During all those excursions their only protection from the harsh lunar environment was that thin spacesuit. In addition, if their rover broke down a walk back to the lunar module would become a race against suffocation.

And even then, they still had to get that lunar module off the ground, rendezvous and dock with the Apollo 15 command module, and then get that module back to Earth safely.

United Kingdom passes comprehensive spaceflight regulations

10:39 am

Capitalism in space: As required by the Outer Space Treaty as well as to lay a framework for commercial and private space launches from within the United Kingsom, the UK this week passed new comprehensive spaceflight regulations that appear modeled closely after already existing regulations in the United States.

From the government’s press release:

The legislation provides the framework to regulate the UK space industry and enable launches to take place from British soil for the very first time. It will unlock a potential £4 billion of market opportunities over the next decade, creating thousands of jobs and benefiting communities right across the UK.

This also puts the UK in a unique position as the first country in Europe able to launch spacecraft and satellites from home soil. This could lead to better monitoring of climate change, as well as improved data for satellite navigation systems, improving journeys right here on the ground, too.

The full law can be read here. It is long, so I have not reviewed it entirely, but it does seem to be closely modeled after several U.S. laws, including the 2004 Space Amendments Act that presently guides FAA regulation and licensing of commercial space launches. The UK even gave its own Civil Aviation Authority (CAA) the same job the FAA has in the U.S.

Inmarsat to launch new low orbit communications satellite constellation

10:23 am

Capitalism in space: Inmarsat announced yesterday that it plans to launch a 150 satellite constellation in low Earth orbit to supplement and improve its already orbiting communications satellites in high geosynchronous orbit.

The company is investing $100 million over the next five years to lay the groundwork for deploying 150-175 LEO spacecraft.

They aim to join satellites Inmarsat has in geostationary and highly elliptical orbits from 2026. Inmarsat, which currently operates 14 satellites, is also on track to add five new GEO and two HEO spacecraft to its network over the next five years.

Its incoming multi-orbit constellation, called Orchestra, seeks to improve latency, network speeds and resiliency for communications services across its core maritime, aviation, government and enterprise markets.

This new constellation is also an effort by Inmarsat to keep its communications product competitive against the newer constellations being launched by SpaceX (Starlink) and OneWeb.

For the space launch industry, this just means more launches, more demand for rockets, and more money to be made.

Note that Inmarsat’s approach here is the correct way to respond to competition. Rather than try to squelch your competitors using government regulation, as Viasat is attempting, Inmarsat is instead up its game, improving its product, and thus matching the challenge its competitors are offering it.

One last question: Will this new constellation, set to be operational by ’26, get there before Amazon’s long promised Kuiper constellation? Right now I’m willing to bet that it will, considering how slow Amazon has been in developing that system.

Apollo 11 lunar ascent stage might still be in orbit around the Moon

10:10 am

New data about the Moon’s interior and gravitational field suggest that the Apollo 11 lunar ascent stage, the part of the LM that carried the astronauts back from the Moon, might still be in orbit around the Moon, rather than have crashed into its surface as long assumed.

Using the GRAIL gravity model and the General Mission Analysis Tool (GMAT) simulator, Meador expected to find the LM’s orbit destabilizing very quickly. What he found – and was verified by a third party using different methods – was that the Ascent Stage had a feedback mechanism that caused the orbit to stabilize itself over a period of every 24 days. When he ran the simulation forward, the orbit remained stable until the present day.

The upshot of this is that the Ascent Stage may still be in orbit now and could be observed when it is in the right position in relation to the Earth and the Sun. However, Meador emphasizes that the LM was never intended to be very robust. Designed to operate for only about 10 days, it was also filled with batteries and fuel tanks, which could have exploded years ago, either destroying the craft or sending it off on a new trajectory.

If the stage is in lunar orbit, than it probably is one the most valuable and quickly reachable artifacts from one of space’s most historic missions. While the Apollo artifacts left on the Moon should be left where they are, this piece could be recaptured and returned to Earth for both study and exhibition.

In fact, if it is still in orbit it should be recovered, to preserve it.

This data also suggests that other Apollo ascent stages as well as other past lunar orbiters might also still be in lunar orbit, and should be located.

Nauka engines fire unexpectedly after docking; forces cancellation of Starliner launch

1:20 pm

The soap opera of the Nauka module to ISS became even more dramatic today when its engines fired unexpectedly after its docking, causing the station to shift in orbit and forcing Russian mission controllers to shut it down and fire other engines to return the station to its proper orbit.

Russia’s Roscosmos space agency attributed the issue to Nauka’s engines having to work with residual fuel in the craft, TASS news agency reported. “The process of transferring the Nauka module from flight mode to ‘docked with ISS’ mode is underway. Work is being carried out on the remaining fuel in the module,” Roscosmos was cited by TASS as saying.

It appears that because they needed to improvise the rendezvous using different engines, there is more fuel left over in Nauka than expected once it docked, and this needs to be vented safely. Somehow, instead of venting the module ignited the engines.

NASA has subsequently postponed tomorrow’s second unmanned demo launch of Boeing’s manned Starliner capsule until the agency has a clear understanding of the issue and has confirmed that Nauka’s presence is not a serious safety issue.

The view from Ingenuity during 10th flight
Click for full image.

Cool image time! Today the Perseverance science team released the 200 images that Ingeniuty took during its 10th flight on July 24, 2021.

The photo to the right was taken about 25 seconds before the helicopter landed, and looks to the southwest. In the foreground can be seen the ridge of rocks and pebbles that the scientists sent Ingeniuty to photograph. In the distance can be seen the rim of Jezero Crater, about 7.5 miles away, with some rounded hills that sit in the crater floor about 5.5 miles away.

The white box indicates the area covered by two high resolution images taken by Perseverance on July 28th that I have combined into the panorama below.

Atomic oxygen in Mars’ atmosphere, as seen by Al-Amal

12:06 pm

Oxygen distribution on Mars

The UAE’s Al-Amal Mars orbiter on July 19, 2021 released a new spectroscopic image, showing the global distribution of atomic oxygen in the Martian upper atmosphere.

The Emirates Ultraviolet Spectrometer (EMUS) mapped the distribution of atomic oxygen in the planet’s upper atmosphere, showing a dense patch emerging from the nightside into the new day.

The photo to the right, cropped and reduced to post here, shows this.

Over the next two years, covering one single Martian year, Al-Amal will monitor the distribution of this oxygen to see how it fluctuations from season to season, as well as from day to day. Gather this information will help the theorists untangle the past atmospheric history of Mars.
