An evening pause: One marching band from Britain is performing to an Italian audience when a band representing the Italian Bersaglieri (mobile light infantry who traditionally run at a trot instead of march) arrives to upstage them.
Silly and staged, but fun nonetheless.

The new colonial movement: China today successfully launched for the first time its new Long March 7A rocket, likely designed to replace its Long March 3B.
The Long March 7A is a 60.1-meter-long, 3.35-meter-diameter kerosene and liquid oxygen launch vehicle with four side boosters, capable of delivering up to 7 metric tons of payload to GTO [geosychronoous transfer orbit]. The launcher draws on new kerosene engine technologies along with a stage modified from the older Long March 3B series, China’s current workhorse rocket, boosting China’s launch options to GTO.
The Long March 7A is more capable than the Long March 3B, which can launch 5.5 tons to GTO. By launching from the coast, it also does not incur the cost and hazards of the inland 3B launches. [China] plans to carry out 3-5 Long March 7A launches a year by 2025. The first launch of the Long March 7A failed in March 2020. A loss of pressure occurred after first stage separation, which led to engine malfunction.
The 2021 launch race:
7 SpaceX
5 China
3 Russia
1 Rocket Lab
1 Virgin Orbit
1 Northrop Grumman
1 India
The U.S. still leads China 10 to 5 in the national rankings.
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 or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
"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
They’re coming for you next: The University of South Alabama this month suspended three professors for wearing Halloween costumes back in 2014, seven years ago.
The photos show “then-Mitchell College of Business dean Bob Wood dressed as a Confederate general and professors Alex Sharland and Teresa Weldy posing with a whip and a noose,” WKRG5 reports.
The three teach in the university’s Mitchell College of Business. Wood and Sharland, who have tenure, have apologized, while Weldy, who is not tenured, “chose not to apologize,” the news station reports.
University brass is reportedly taking heat from the campus community for being aware of the photos since 2020 but not doing more about it. With that, [university President Tony] Waldrop upped his efforts on the nearly 7-year-old matter, calling the costumes and poses “offensive” and “contrary to our core principles of diversity and inclusion.” He pledged in his statement that the university will “address this situation in a manner that demonstrates our unwavering commitment to diversity, inclusion, and a safe and welcoming environment for every member of our community.” [emphasis mine]

Though the present excitement over the spectacular images and sounds coming down from Perseverance is certainly warranted, what must be understood is that this rover is presently only at the beginning of its journey, and is thus sitting on relatively boring terrain, from a merely visual perspective. The scientists might be excited, but to the general public, all we really are seeing is a flat dusty desert with some scattered rocks on the floor. In the far distance can be seen some hills and mountains (Jezero Crater’s rim), but they are very far away.
Curiosity, which the press and the public has largely forgotten about, is actually just beginning what will likely be the most breath-taking part of its journey. As I noted in my last rover update last week, Curiosity is now at the very base of Mount Sharp, and is about to enter the mountain’s canyons and initial slopes. For its past eight-plus years of roving it has been on the flat floor of Gale Crater, followed by some weaving among the smallest foothills of Mount Sharp. The views have been intriguing and exciting from a research perspective, but hardly breath-taking from a picture-taking point of view.
That is now changing. The picture below, taken by Curiosity just this week, gives us a taste of what is to come.

Capitalism in space: On March 9th the Space Force announced that it has awarded four new launch contracts, two each to ULA and SpaceX, for a total cost of just under $400 million, all to launch in ’23.
Under the task orders issued March 9, ULA and SpaceX will each launch two missions. ULA was awarded $225 million to launch and integrate the USSF-112 and USSF-87 missions on its Vulcan Centaur rockets while SpaceX was awarded $160 million to launch and integrate USSF-36 and launch NROL-69 on its Falcon 9 rockets.
Based on these numbers it appears ULA is charging about $113 million per launch for its new Vulcan Centaur rocket, while SpaceX is charging about $80 million using its Falcon 9.
For ULA, that is less that what it would charge using its Atlas 5 rocket, but not by much. For SpaceX this price is high, probably because the military might be demanding the company use new boosters for its launches.
These high prices for both are to me a sign of how little our federal government cares about saving any money for the taxpayer. While the competition brought on by SpaceX’s arrival is saving the military money, the way these contract awards are structured, with both ULA and SpaceX guaranteed to win them, neither company has an incentive to reduce its prices. Instead, they can overcharge and the military can do nothing about it.
In a more sane world the military would use the competition in the launch market to get an ever better deal. Instead, our federal government sees its budget as a blank check, and they are using it.
Capitalism in space: Northrop Grumman’s second Mission Extension Vehicle (MEV-2) is presently doing the last rendezvous maneuvers in the vicinity of one of Intelsat’s operating geosynchronous communications satellites in anticipation to its docking, when it will extend that satellite’s life by up to five years.
This is the second MEV to fly. The first successfully docked with a defunct 19-year-old satellite and brought it back into operation.
Meanwhile, in the Ukraine a new startup is proposing to use an upgrade of the automatic rendezvous and docking system once used by Progress and Soyuz capsules to create its own variation of MEV.
Kurs Orbital is raising $6.5 million in its first investment round this summer to start the demonstration vehicle that will rendezvous with an uncooperative object in low Earth orbit, he said. “I think that we will be on schedule for 2023 with a demonstration mission.”
The company plans to raise more money over the next few years to build a fleet of four vehicles to start offering de-orbiting services by 2025. Usov said de-orbiting is the low hanging fruit because it is a way to immediately help satellite operators make money.
Operators currently take geostationary satellites out of service to a graveyard orbit six to eight months before they are out of fuel. De-orbiting services would allow operators to keep the satellites in operation for several additional months and continue to generate revenues, Usov said. Those extra revenues would more than pay for the $10 million to $15 million de-orbiting service.
If successful, this company will be the third attempting to enter the robotic satellite serving business, with a number of others also aiming to make money removing space junk.

Even as the National Science Foundation (NSF) proceeds with the disassembly of the destroyed Arecibo radio telescope in Puerto Rico, some astronomers are proposing that a new radio telescope be built in its place, with a new design that will not require the instrument platform floating above a single dish.
Here’s the idea as outlined in a white paper circulated by Roshi and his colleagues: The Next Generation Arecibo Telescope would pack hundreds, maybe even more than 1,000 smaller radio dishes into the same space now occupied by the single 305-meter dish. Those smaller antennas would combine forces to act like a single larger telescope (no suspended instrument platform required).
Ideally, those dishes would be on a single, tiltable platform to access more of the sky from the Arecibo site; it’s possible multiple platforms could do the same.
The revamped telescope would have twice the sky coverage of the legacy dish, 500 times the field of view in individual images, at least double the sensitivity, and five times the radar power.
The cost for this new radio telescope is presently estimated to be about half a billion. Considering that the NSF didn’t have the money to operate the old Arecibo telescope, which was why it wasn’t properly maintained and collapsed, I doubt it has the cash to build this replacement. Congress, which likes printing money it doesn’t have, might step in and fund it, but if so that will only add to the national debt that is certainly going to cause the bankruptcy of the nation at some point in the future, a point that is getting closer and closer with each new trillion that Congress nonchalantly spends, on almost a monthly schedule.
NASA has now scheduled the next static fire test of the core stage of its SLS rocket for March 18th.
The background:
NASA attempted the hot fire test on January 16, but computers terminated the test after 67 seconds instead of 485 seconds because of the conservative test parameters that were set. This is not a test vehicle, but the actual core stage that will be used for the first SLS launch. NASA needs to ensure the testing does not damage it.
NASA decided to redo the test and scheduled it for February 25, but a problem with a pre-valve forced another delay.
If this March test is successful, it will take a month to prep the core stage for shipment by barge to Florida, where it will take several months to prep it for launch linked to its two solid rocket boosters now stacked and ready for launch. If that schedule moves fast, NASA is still aiming for a late ’21 launch, though most industry experts expect that date to shift into early ’22.
If the March test has any problems however this schedule goes out the window. Worse, it increases the chance that the two boosters will have reached the end of their 12-month use-by date (approximately December ’21), and will have to be dissembled and inspected. If that happens the launch will certainly be delayed by many months.
There is another possibility. NASA might waive that 12-month use-by date requirement for the boosters. If the agency does this, however, it will be another example of the same management mistakes that caused both the Challenger and Columbia shuttle failures, a desire to put aside proper engineering to meet a schedule.
One more thought: That it takes about four months to assemble the solid rocket boosters for SLS illustrates well the cumbersome and inefficient nature of this rocket. Launches not only cannot happen within days, they really cannot happen for months. Depending on such a rocket with such a low launch cadence will make the exploration of the solar system practically impossible.
Capitalism in space: SpaceX last night successfully launched another sixty Starlink satellites, raising the total launched to 1,265, with more than a thousand operating.
The company also landed the Falcon 9’s first stage for the sixth time while reusing both fairings.
The 2021 launch race:
7 SpaceX
4 China
3 Russia
1 Rocket Lab
1 Virgin Orbit
1 Northrop Grumman
1 India
The U.S. now leads China 10 to 4 in the national rankings. In fact, SpaceX alone has as many launches as China and Russia combined.
An evening pause: An animation that actually is real and useful, showing the full rebuild of a dirt bike engine.
What struck me is the number of parts and pieces and their complexity. Pause and consider the engineering thought that went into creating this and all such engines.

Today’s cool image is once again another of what I dub a “what the heck?” photo. The picture to the right, cropped to post here, was taken on December 17, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and captures some very strange ridges on the plateau above Mars’ biggest canyon, Valles Marineris.
The image, labeled merely as a “terrain sample,” was taken not as part of any specific research project but scheduled by MRO’s science team in order to maintain the camera’s temperature. When they do this they try to take pictures covering something interesting, but often it is a potshot that sometimes shows little of interest.
In this case the photo shows something very strange. The ridges in the sample are packed into one area only, but if you look at the full image you will see that they are also scattered about randomly and sometimes isolated on the flat plains surrounding this spot.
Interestingly, these ridges resemble the first “What the heck?” image I ever posted in 2019. That photo was located at about the same elevation as these ridges, but due west in the volcanic plains near Mars’s giant volcanoes and just off the western edge of the overview map below.

The new colonial movement? In what appears to be a complete surprise within its own scientific community, the government of Nicaragua today announced the formation of its own space agency.
[T]he National Assembly approved the creation of the agency for the “defence of supreme interests” in space. It will seek “to expand the country’s capacities in the educational, industrial, scientific and technological branches”, according to president Daniel Ortega´s proposal.
The article at the link provides little information about this government effort, and instead is mostly filled with commentary by other scientists expressing their opposition to it. Nor can I blame them. Unlike rich countries like the UAE, Nicaragua is one of the poorest in Latin America. It can’t afford to buy the educational resources of the United States, as the UAE did.
Moreover, it is ruled by a socialist/communist government whose ability to produce wealth is exceedingly limited. If anything, the nation’s poverty is because of that government’s top-down policies. Establishing a space agency is merely another aspect of this approach, and will likely only act to provide photo ops for its leaders and little benefit to its citizens.
