The steep sudden foothill of Olympus Mons

May 20, 2021 2:27 pm Robert Zimmerman

Olympus Mons on Mars

Today’s cool image starts from afar and zooms inward. The elevation map to the right shows Olympus Mons, the largest volcano on Mars and in fact the entire solar system. About 600 miles across, from the edge to its peak this volcano rises about 54,000 feet, with an actual height relative to Mars’ “sea level” of just under 70,000 feet, more than twice as high as Mount Everest on Earth.

The cross-section of this volcano is so large it would cover almost all of France if placed on Earth. As a shield volcano, it was formed by many many volcano flows that laid down many layers of lava, with some in its northwest quadrant thought to be as recent as 2 to 115 million years ago.

Our cool image today is located at the white rectangle at the southeast edge of this volcano, and illustrates how those many lava flows could create such a large shield volcano with such a large cross section.

China scrubs launch of Tianzhou freighter to its Tianhe station module

May 20, 2021 12:24 pm Robert Zimmerman

The first launch of a Tianzhou freighter to China’s first module, dubbed Tianhe, of its planned Chinese Space Station (CSS), was scrubbed early this morning for unstated “technical reasons.”

Not only has China’s state-run press or its space agency not revealed what caused the scrub, they have said nothing about a new launch date. This cargo freighter however apparently needs to be in place before the arrival of the station’s first crew, now roughly scheduled for sometime in June.

SpaceX begins stacking Superheavy prototype for flight

May 20, 2021 12:06 pm Robert Zimmerman

Capitalism in space: It appears that the third Superheavy prototype, BN3 (Booster #3), is now being stacked and prepared for the first near-orbital flight of Starship, which SpaceX is still hoping to launch before the end of this year.

SpaceX has at least six BN3 sections – amounting to 22 rings and two of three tank domes – either completed or awaiting integration. The process of stacking BN3 began sometime in the last 7-10 days when SpaceX joined two four-ring sections – including the booster’s common dome, likely pictured above.

SpaceX has mostly completed BN3’s engine section, including a thrust dome with plumbing cutouts for a full 28 Raptor engines. Most recently, what looks like a Super Heavy fuel manifold appeared in Boca Chica. That manifold will attach to the end of a supersized Super Heavy transfer tube – also spotted in work – used to route methane through the liquid oxygen tank to fuel its Raptor engines. Fueling 28 large, high-performance Raptors is no mean feat and requires a rat’s nest of plumbing to feed them more than 15 metric tons (~30,000 lb) of propellant every second at full throttle.

Put simply, a majority of Super Heavy booster BN3’s hardware appears to be ready or almost ready for integration. The eight rings now stacked represent approximately 20% of the rocket’s full height, leaving another 30 or so rings – 54m (~180 ft) – to go.

That flight, the flight plan of which has already been submitted to the FCC, would take off from Boca Chica, circle about three-quarters of the globe, and land in the Pacific to the northwest of Hawaii. While not a full orbit, this flight would demonstrate an orbital capability while allowing for a controlled safe re-entry at a planned location, a wise approach for that first orbital attempt.

Today’s blacklisted American: Former Trump official Sebastian Gorka

May 20, 2021 11:42 am Robert Zimmerman

The Bill of Rights cancelled at Facebook and Instagram
Does not exist at Google or YouTube.

They’re coming for you next: Along with all other former Trump officials being blackballed by today’s dominant leftist culture, former Trump deputy assistant Sebastian Gorka has found himself banished, first from Fox News, and then from Google’s YouTube.

While Gorka’s problems at YouTube were in the past related to copyright disputes, the final ban last month was simply part of that site’s effort to censor any legitimate discussion of election fraud during the November 2020 election. From their own spokesman:

“In accordance with our long standing strikes system, we terminated the channel America First with Sebastian Gorka, for repeated violations of our presidential election integrity policy,” Ivy Choi, a YouTube spokesperson, wrote in an email to The Hill. … “As we’ve publicly shared, our presidential election integrity policy prohibits content uploaded after last year’s safe harbor deadline that alleges widespread fraud or errors changed the outcome of the 2020 U.S. presidential election,” Choi wrote. “Any channel that violates this policy will receive a strike and channels that receive three strikes in the same 90-day period are permanently removed from YouTube, as in the case of America First with Sebastian Gorka.”

Parker makes course correction

May 20, 2021 9:25 am Robert Zimmerman

On May 15th the Parker Solar Probe made the first of three small adjustments to its orbital path in order to refine its path during an October 16th fly-by of Venus, which in turn will make more precise its next three Venus fly-bys and thus bring it closer and closer to the Sun.

[The] Parker Solar Probe just completed its eighth close approach to the Sun, coming within a record 6.5 million miles (10.4 million kilometers) of the Sun’s surface on April 29. It’ll pass the Sun from about the same distance again on Aug. 9, before using Venus’ gravity on Oct. 16 to swing it even closer to the surface — about 5.6 million miles (9 million kilometers) — on Nov. 21. Assisted by the remaining three Venus flybys, Parker Solar Probe will eventually come within 4 million miles (6.4 million kilometers) of the solar surface.

The spacecraft remains healthy and continues to gather data with each fly-by of the both the Sun and Venus.

Ingenuity to make sixth flight next week

May 20, 2021 9:17 am Robert Zimmerman

Future travels for Perseverance and Ingenuity

The Ingenuity engineering team announced today that the Mars helicopter will make its sixth flight next week, flying to a new landing spot while taking images for the Perseverance science team.

Ingenuity’s flight plan begins with the helicopter ascending to 33 feet (10 meters), then heading southwest for about 492 feet (150 meters). When it achieves that distance, the rotorcraft will begin acquiring color imagery of an area of interest as it translates to the south about 50-66 feet (15-20 meters). Stereo imagery of the sand ripples and outcrops of bright rocks at the site will help demonstrate the value of an aerial perspective for future missions. After completing its image collection, Ingenuity will fly about 164 feet (50 meters) northeast where it will touch down at its new base of operations (known as “Field C”).

The flight will attempt a new speed record of 9 mph, and will also land for the first time in a spot that the helicopter has not scouted beforehand. It will instead be using data from high resolution images from Mars Reconnaissance Orbiter (MRO) combined with its own hazard avoidance system.

Ingenuity will essentially place itself over and in an area where Perseverance plans to go, leapfrogging ahead flight by flight, as shown by the map above (annotated by me from the map available here). The green dot numbered 5 shows the helicopter’s present position, while #6 shows its approximate landing spot after its sixth flight. Perseverance, whose present location is indicated by the blue marker, is generally heading south within the area outlined by the red line, as described during the science team’s an April 30th press conference. The goal in exploring this region is to gain a very robust geological baseline of the floor of Jezero Crater, which scientists believe will be the oldest material the rover should see in its travels.

Bidding for ticket on first New Shepard manned suborbital flight reaches $2.8 million

May 20, 2021 8:37 am Robert Zimmerman

Capitalism in space: The first phase in Blue Origin’s auction for the purchase of the first seat on its New Shepard suborbital spacecraft in July has closed, with the high bid now $2.8 million.

Amazon CEO Jeff Bezos’ Blue Origin space venture has begun unsealing the bids for an open seat on its New Shepard suborbital spaceship, and the high bid hit the $2.8 million mark with more than three weeks to go in the online auction.

Blue Origin says the auction has drawn out more than 5,200 bidders from 136 countries. … Bidding started on May 5 and will conclude with a live auction on June 12. Proceeds from the sale will be donated to Blue Origin’s educational foundation, the Club for the Future.

The first phrase involved sealed secret bids, and ended with the high bid at $1.4 million. The second phase, on-going now with bidding quite brisk, makes the high bid visible to all bidders.

The $2.8 million bid is far higher than the estimated price point predicted for this suborbital flight, which had been in the range of several hundred thousand dollars. The high price is likely because this will be the first flight, and people with cash are willing to spend it to get bragging rights to that seat. At the same time, the high bidding suggests that the previous estimated ticket price might have been low, at least for the first flights.

With three weeks left before the final live auction on June 12th, there is a chance the winning bid could get even higher.

Typical but still mysterious gullies in a crater on Mars

May 19, 2021 1:40 pm Robert Zimmerman

Today’s cool image to the right, cropped and reduced to post here, is of a crater in the mid-latitudes of Mars’s cratered southern highlands. The picture was taken on January 4, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and is actually the only high resolution image ever taken of this crater.

The gullies in the north interior wall of this crater are the reason why this picture was snapped. These gullies are very typical on the pole-facing slopes of mid-latitude Martian craters, and have puzzled scientists since they were first discovered in the late 1990s in images taken by Mars Global Surveyor. Since then, thousands have been found, almost all of which in the 30 to 60 degree mid-latitude bands where glacial features are also found. Most occur on the more shadowed pole-facing interior slopes of the craters, though at higher latitudes they are also found facing the equator.

Since their discovery scientists have puzzled over their cause, which because of their locations favoring colder temperatures suggest some form of seasonal weather factor. The most preferred hypotheses propose some interaction with water ice or dry ice, or are simply dry flows of rocky granular material. None of these hypotheses have been confirmed. Some evidence suggests they are dry flows, no water involved. Other evidence points to the influence of an underground layer of water ice.

The mystery of these gullies is enhanced by by the wider view from MRO’s context camera below, rotated and cropped to post here.

Today’s blacklisted American: Long-time scholar banned for questioning gender fluidity

Pennsylvania votes to severely limit governor’s emergency powers

May 19, 2021 10:48 am Robert Zimmerman

Good news: Pennsylvania voters yesterday soundly approved constitutional amendments that severely limit the emergency powers of their governor, thus preventing the present and future governors from endlessly renewing such powers.

One would give the General Assembly the ability to end or extend a declared emergency without the involvement of the governor, and the other would end a declared emergency after 21 days unless extended by the General Assembly.

Previously, once the governor’s emergency powers were granted they would last for 90 days, and the governor himself could automatically renew them endlessly. This is what Democrat governor Tom Wolf has been doing for the past year. His last renewal however expires tomorrow. It is unclear whether this vote will forbid him from renewing those dictatorial powers again.

The vote however signals to all Pennsylvania politicians the hostility the voters have to these endless emergency powers and the abuse of power that has resulted.

This vote in Pennsylvania also shows us the way to freedom. Reform must come from the states, the cities, and the local school boards, not at the federal level. If enough states make changes to their laws to strengthen their voting systems to prevent what has become almost routine Democratic Party fraud, that party will lose power at all levels. If enough parents get involved in school board activities, the politicization of education for the purpose of leftist indoctrination will end.

Once these things happen, reform at the federal level might finally have a chance.

Good people have got to stop doing nothing. Time is running out. Soon it will be too late for them to do anything.

Senate revises NASA authorization to protect lunar lander award to SpaceX’s Starship

May 19, 2021 9:47 am Robert Zimmerman

Even as the full Senate today begins its review of NASA’s newest authorization, the bill has been modified to grandfather in the contract award that NASA gave to SpaceX to build its manned lunar lander using Starship.

An earlier version of the bill had included language inserted by Senator Maria Cantwell (D-Washington) demanding NASA award within 30 days a contract for a second lunar lander. The modified bill extends that timeline to 60 days, but also specifically protects SpaceX’s contract award:

The Administrator shall not, in order to comply with the obligations referred to in paragraph (1), modify, terminate or rescind any selection decisions or awards made under the human landing system program that were announced prior to the date of enactment of this division.

The revised bill still puts NASA in a ridiculous position. Combined with Cantwell’s amendment, the agency will now be forced to name a second lunar lander contract within sixty days. Though it recommends doubling the money for this program ($10 billion over five years instead of ten), it does not actually appropriate it. Moreover, that new budget recommendation is still about one half of what NASA had originally requested in order to fund the construction of two lunar landers.

Not surprisingly, the entire bill [pdf] has become a pork-laden collection of spending put together without any concern for the needs for the nation. Instead, ithe 1,445-page long bill “is the proverbial ‘Christmas tree’ with a Table of Contents that alone is 15 pages” that different senators keep adding items to, making it a hodge-podge of incoherence.

The bill itself however still has to be approved by both the Senate and the House. While this should act as a corrective to make it more sane, don’t expect that. Instead, the more likely result will be that the two houses of Congress will combine together their own personal earmarks into one humongous bill.

Discovery channel to launch contest to fly winner to space

May 19, 2021 9:19 am Robert Zimmerman

Capitalism in space: The Discovery channel today announced that it is planning a contest where the winner will win an eight-day flight to ISS in partnership with the space tourism company Axiom.

The casting call on Discovery’s website says that eligibility is limited to U.S. residents or citizens, with additional requirements to be disclosed. For now, there are few other details about eligibility for hopeful astronauts applying to the Discovery show, the expected challenges entrants will face and who will serve as judges for the competition, as the series isn’t expected to start filming until next year.

It is so far unclear whether or not eligibility may include people with physical disabilities, but the casting call does include questions about your degree of impairment with physical activities. (The European Space Agency’s current astronaut process is open to candidates with physical disabilities, and the forthcoming Inspiration4 mission includes Hayley Arceneaux, who has a prosthetic limb after childhood bone cancer.)

Discovery said the series will be in eight parts and will chronicle a “grueling” process. “The series will follow each of the contestants competing for the opportunity in a variety of extreme challenges designed to test them on the attributes real astronauts need most, and as they undergo the training necessary to qualify for space flight and life on board the space station,” the channel said in a statement.

It is unclear exactly when this mission will fly, but based on its description and timing I suspect it will not be for several years, and might actually take place after Axiom installs its own module to ISS in ’24.

1st pictures from Zhurong finally released

May 19, 2021 9:09 am Robert Zimmerman

Click for full image.

China today finally released the first images from its Mars rover Zhurong, proving that the rover landed successfully and is operating as planned. The link takes you to the website of the Chinese space agency, in Chinese. This link provides some details in English.

The two images to the right show the front and rear views from Zhurong, sitting on top of its landing. The black & white front view shows the deployed ramps that the rover will roll down when it begins it operational phase. It shows, as expected, the generally flat terrain of the northern lowlands plains of Utopia Planitia. In the distance however there appears to be distinct features, possibly the rim of a small crater. At the moment the exact location of the rover is not known, so no precise map yet exists of its surrounding terrain. This will change in the coming days as both Chinese and American scientists hone in on the rover using orbital images.

The color rear view shows that the rover’s solar panels and high gain antenna have properly deployed. While the design of Zhurong in many ways imitates the two American rovers Spirit and Opportunity (probably because China hacked into the JPL website for several years and downloaded their blueprints), it also includes several upgrades. For example, Zhurong’s solar panels unfold, providing a significantly larger surface area to gather sunlight. Both Spirit and Opportunity were somewhat hampered by the power they could obtain by their smaller solar panels. Both also experienced times when Martian dust on the panels reduced that power. Zhurong’s much larger panels will protect it better from these issues, and could allow it to survive longer on Mars.

Martian mesas made entirely of dry ice!

May 18, 2021 1:27 pm Robert Zimmerman

Click for full image.

Time for an especially cool image! The photo to the right, taken on February 13, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and cropped and reduced to post here, shows some mesas on the south polar ice cap of Mars.

What makes those mesas cool (literally and figuratively) is that they are thought to be made up entirely of dry ice, part of the thin but permanent frozen carbon dioxide cap in the south. As explained to me by Shane Byrne of the Lunar and Planetary Lab University of Arizona, who requested this image from MRO,

[These mesas are] unusually thick compared to other dry ice mesas (a common landform in the residual ice cap). I only have the lower resolution laser altimeter data to go off for heights here (we may get a stereo pair next year), but from that it looks like 13 meters thick.

That’s about forty feet high, from base to top. In length, the largest mesa on the left is about a mile long and about 1,500 feet wide, on average. And it is made entirely of dry ice!

The red cross on the map below shows the location of these mesas on the south pole ice cap.

This was the first Atlas 5 launch in 2021. The satellite has now been deployed into its transfer orbit taking it to its final geosynchronous orbit.

The U.S. now leads China 21 to 12 in the national rankings. Note also that though we are still six weeks short of the year’s halfway point, the U.S. is already more than halfway to its total from all of 2020, 40 launches. If this pace continues the U.S. has a good chance of reaching launch totals that were only routine during the mid-1960s, at the height of the beginnings of the space race.

NASA gives an American the seat on Dragon flight that it had been holding for Russian

May 18, 2021 10:15 am Robert Zimmerman

NASA yesterday announced that it has added an American astronaut to the next manned mission to ISS, set for October.

NASA said that Kayla Barron will join the Crew-3 mission, launching on a SpaceX Crew Dragon spacecraft scheduled for launch no earlier than Oct. 23. Barron joins NASA astronauts Raja Chari and Tom Marshburn, and European Space Agency astronaut Matthias Maurer, who had been assigned to Crew-3 last December.

The Crew-3 mission will relieve the Crew-2 astronauts who arrived at the station on another Crew Dragon spacecraft April 24. The four Crew-3 astronauts will remain on the station for a six-month stay.

The space agency had been holding that seat open for a Russian, as part of its long term barter arrangement whereby in exchange for flying Americans on Soyuz capsules, Russia flies Russians on American spacecraft. That arrangement had been used repeatedly when the shuttle was flying, but since its retirement the U.S. has been forced to buy its seats on Soyuz as it had nothing to offer in exchange.

With the arrival of SpaceX’s Dragon capsule however NASA has been trying to get the Russians to renew that arrangement. And though an American, Mark Vande Hei, flew for free on a Soyuz last month, the Russians have as yet refused to assign their own astronaut to this upcoming October flight, despite months of negotiations. It appears NASA decided it could wait no longer, and filled the seat with its own astronaut.

In fact, the announcement by Roscosmos on May 13th that the next two Soyuz launches to ISS will carry two commercial passengers each means that Vande Hei cannot return on a Soyuz until next year. The seat he would have used to come home now must be used by these tourists, meaning his mission will now be extended to last for as much as a full year or more.

Unless of course NASA decides to bring him home on a Dragon capsule instead.

China rolls out rocket for next space station launch

May 18, 2021 10:00 am Robert Zimmerman

The new colonial movement: On May 15th China rolled out the Long March 7 rocket that on May 20th will carry the first Tianzhou cargo freighter to the already launched core module of its space station.

Tianzhou-2 will carry 4.69 tons of cargo in a pressurized segment and 1.95 tons of propellant, according to the China Manned Space Agency (CMSA).

Meanwhile, the core stage, dubbed Tianhe, has successfully completed its on-orbit checkouts and has placed itself in the right orbit for the arrival of Tianzhou.

If all goes right with this cargo mission, China is targeting a June launch for the station’s first three-man crew, who will attempt to stay at the station for three months.

Do not expect much information to be released by China during these missions. Like the Soviet Union of old, and as they have been doing routinely since their space program began to gear up in the past decade, they will only make periodic terse announcements, all of which will contain only the most superficial of information. Only much later will more be learned, usually many years after the fact when its news value has vanished and it only concerns historians and space buffs.

Flash! SpaceX to use a NEW Falcon 9 1st stage!

May 18, 2021 9:48 am Robert Zimmerman

Both side boosters landing during
the 1st Falcon Heavy launch

Capitalism in space: For the first time in since September 2020, SpaceX has delivered a new Falcon 9 1st stage to its Florida launch site in preparation for launch.

This new stage will be used on the June 3rd launch of a cargo Dragon freighter to ISS.

What is remarkable about this story is that it is news that SpaceX is using a new first stage. Not only have all of their fifteen launches in 2021 lifted off with used boosters, since November 2020 they have completed nineteen launches using only used boosters.

That’s 19 launches in only six months, all with previously flown boosters!

During that time the company’s Falcon rocket division has apparently dedicated its time in upgrading and building new Falcon Heavy 1st stage boosters, in preparation for the first Falcon Heavy launches since June 2019, set for July and October later this year. I suspect the focus has been an effort to upgrade the core booster so that it will be successfully recovered this time, something that did not occur on two of the first three Falcon Heavy launches in 2018 and 2019..

Texas: No masks, no restrictions, now no COVID deaths!

May 17, 2021 3:24 pm Robert Zimmerman

Surprise! Surprise! Two months after lifting business restrictions and mask mandates, Texas reported yesterday no deaths linked to COVID.

Once again the fear-mongers were wrong. Biden called the officials in both Texas and Mississippi “neanderthals” for their decisions to end lockdowns and mask requirements. Others predicted a wave of deaths that would boggle the mind.

Instead, cases of COVID dropped quickly, to actually reach zero for the first time in fourteen months. Though I am sure there will be new coronavirus cases and deaths, that the numbers dropped after removing the stupid lockdowns and mask mandates is just another illustration of how failed a policy those lockdowns and mask mandates were.

Nor is any of this a surprise to anyone who has read this website for the past year. I have been saying from day one that the lockdowns were a terrible mistake, and that the mask mandates were not only useless but possibly very counter-productive. As another writer noted today, “The Neanderthals were right.”

Where is China’s Zhurong Mars rover?

May 17, 2021 2:13 pm Robert Zimmerman

At this moment we do not have confirmation that China’s rover Zhurong landed safely on Mars. Assuming it did, the mosaic to the right, made from two images from Mars Reconnaissance Orbiter’s (MRO) context camera, shows that landing zone, with the white cross indicating the centerpoint of the suspected landing site, as leaked to the Chinese press back in October 2020.

The red boxes are the only two images released by China that were taken by its Tianwen-1 orbiter of this landing zone. The two white boxes show the areas covered by two of the seven or so photographs taken by MRO’s high resolution camera since that location was revealed. Below is a map showing all the images MRO has taken of this location.

Why no visual confirmation of the landing on Mars of China’s Zhurong rover?

May 17, 2021 12:03 pm Robert Zimmerman

Despite more than 48 hours having passed since China announced the successful landing of its Zhurong rover on Mars in the northern lowland plain of Utopia Planitia, no images or data of any kind has been released by that nation or its space agency.

It is very possible that this is totally expected, since they have always said they will need about a week of checkouts before they rollled the rover off the lander and begin its operations.

At the same time, China has been very very creative with providing early images for all its planetary missions. For example, within hours of landing they had released images from their Chang’e-5 lunar sample return lander. Similarly, only hours after Chang’e-4 landed on the far side of the Moon with its Yutu-2 rover China released images.

They did the exact same thing when Chang’e-3 landed in 2013 with its Yutu-1 rover.

I can’t imagine they don’t have some cameras on the Mars lander to snap pictures of the horizon or the ground directly below. They might not, but if so the lack would be truly astonishing.

It is also possible China is holding the data close for any number of political reasons, though this doesn’t make much sense since the whole political point of these planetary missions is to sell China to the world.

The more time that passes with no confirmation data, the more it will appear that something is wrong. If this conclusion is incorrect, China needs to act now to dispel these doubts.

Today’s blacklisted American: Space Force officer fired for criticizing Marxism and condemning bigotry

May 17, 2021 11:12 am Robert Zimmerman

Twitter's idea of debate
Show trials: What America’s Space Force apparently wants.

Blacklists are back and the military’s got ’em: Lt. Col. Matthew Lohmeier, a fourteen year veteran of the Air Force who became one of the first officers in the Space Force, has been fired by his superiors because he wrote a book criticizing Marxism and compounded that sin by repeating the criticisms, along with criticisms of the undeniable bigotry of critical race theory, on a public podcast.

From a military pr officer:

“This decision was based on public comments made by Lt. Col. Lohmeier in a recent podcast,” a Space Force spokesperson said in an email. “Lt. Gen. Whiting has initiated a Command Directed Investigation on whether these comments constituted prohibited partisan political activity.”

Lohmeier’s temporary assignment in the wake of his removal was not immediately clear. [emphasis mine]

In addition, Amazon has decided to shadow ban Lohmeier’s book, Irresistible Revolution.

Irresistible Revolution has debuted in a strong position and as of this writing, it is #2 and #3 in military policy on Amazon, despite the fact that within hours of Lohmeier being relieved of his command, the book was no longer searchable on the publishing giant’s website. Only a direct link to the book’s page works at this time. It is available at Barnes & Nobles and other online booksellers such as Hudson and AbeBooks.

Lohmeier notes that he wrote the book entirely on his own time. He also informed the military of its existence and offered to have them review it before publication. The Pentagon said such a review was not required.

So what exactly did Lohmeier say that made his superior, Lt. Gen. Steven Whiting, believe he was participating in “partisan political activity”? From the Military.com come article:

SpaceX launches 52 Starlink + 2 customer satellites

May 15, 2021 4:09 pm Robert Zimmerman

Capitalism in space: SpaceX today successfully launched another 52 Starlink satellites along with two smallsat satellites.

They have put just under 1,700 Starlink satellites into orbit. The first stage completed its 8th launch, and the fourth in 2021, according to the SpaceX announcer. Let me repeat that: That’s four launches of the first stage in less than five months. The fairing halves were also flying on their second flight.

The leaders in the 2021 launch race:

15 SpaceX
12 China
7 Russia
2 Rocket Lab

The U.S. now leads China 20 to 12 in the national rankings.

Rocket Lab launch fails

May 15, 2021 9:22 am Robert Zimmerman

Rocket Lab’s launch yesterday of its Electron rocket failed when the upper stage began tumbling right after stage separation and engine start.

This was the second Electron failure in twenty launches. The last, in July 2020, was also caused by a problem in the upper stage, though far less dramatic. In that case an electric failure caused the upper stage engine to shut down prematurely before it had reached orbit.

Though the launch was a failure, the recovery of the first stage as part of Rocket Lab’s effort to make it reusable appears to be proceeding as planned. According to the company’s statement:

Electron’s first stage safely completed a successful splashdown under parachute and Rocket Lab’s recovery team is working to retrieve the stage from the ocean as planned.

I have embedded below the fold the Rocket Lab live feed, cued to just before the failure. You can see that as soon as the upper stage fires it begins to tumble.
