Eleven months after the Ingenuity helicopter made its final flight on Mars, engineers and scientists at NASA and a private company that helped build the flying vehicle said they have identified what probably caused it to crash on the surface of Mars.

In short, the helicopter's on-board navigation sensors were unable to discern enough features in the relatively smooth surface of Mars to determine its position, so when it touched down, it did so moving horizontally. This caused the vehicle to tumble, snapping off all four of the helicopter's blades.

Delving into the root cause

It is not easy to conduct a forensic analysis like this on Mars, which is typically about 100 million miles from Earth. Ingenuity carried no black box on board, so investigators have had to piece together their findings from limited data and imagery.

Blue Origin said Tuesday that the test payload for the first launch of its new rocket, New Glenn, is ready for liftoff. The company published an image of the "Blue Ring" pathfinder nestled up against one half of the rocket's payload fairing.

"There is a growing demand to quickly move and position equipment and infrastructure in multiple orbits," the company's chief executive, Dave Limp, said on LinkedIn. "Blue Ring has advanced propulsion and communication capabilities for government and commercial customers to handle these maneuvers precisely and efficiently."

This week's announcement—historically Blue Origin has been tight-lipped about new products, but is opening up more as it nears the debut of its flagship New Glenn rocket—appears to serve a couple of purposes.

Within hours of NASA announcing its decision to fly the Artemis II mission aboard an Orion spacecraft with an unmodified heat shield, critics assailed the space agency, saying it had made the wrong decision.

"Expediency won over safety and good materials science and engineering. Sad day for NASA," Ed Pope, an expert in advanced materials and heat shields, wrote on LinkedIn.

There is a lot riding on NASA's decision, as the Artemis II mission involves four astronauts and the space agency's first crewed mission into deep space in more than 50 years.

Orbex pauses launch site work in Sutherland, Scotland. Small-launch vehicle developer Orbex will halt work on its own launch site in northern Scotland and instead use a rival facility in the Shetland Islands, Space News reports. Orbex announced December 4 that it would "pause" construction of Sutherland Spaceport in Scotland and instead use the SaxaVord Spaceport on the island of Unst in the Shetlands for its Prime launch vehicle. Orbex had been linked to Spaceport Sutherland since the UK Space Agency announced in 2018 it selected the site for a vertical launch complex.

President-elect Donald Trump announced Wednesday his intent to nominate entrepreneur and commercial astronaut Jared Isaacman as the next administrator of NASA.

For those unfamiliar with Isaacman, who at just 16 years old founded a payment processing company in his parents' basement that ultimately became a major player in online payments, it may seem an odd choice. However, those inside the space community welcomed the news, with figures across the political spectrum hailing Isaacman's nomination variously as "terrific," "ideal," and "inspiring."

This statement from Isaac Arthur, president of the National Space Society, is characteristic of the response: "Jared is a remarkable individual and a perfect pick for NASA Administrator. He brings a wealth of experience in entrepreneurial enterprise as well as unique knowledge in working with both NASA and SpaceX, a perfect combination as we enter a new era of increased cooperation between NASA and commercial spaceflight."

SpaceX recently hit some notable milestones with its workhorse Falcon 9 rocket, and even in the full context of history, the performance of the vehicle is pretty incredible.

Last Tuesday, the company launched a batch of Starlink v2-mini satellites from Kennedy Space Center in Florida on a Falcon 9 rocket, marking the 400th successful mission by the Falcon 9 rocket. Additionally, it was the Falcon program's 375th booster recovery, according to SpaceX. Finally, with this mission, the company shattered its record for turnaround time from the landing of a booster to its launch to 13 days and 12 hours, down from 21 days.

But even though it was mere hours before the Thanksgiving holiday in the United States, SpaceX was not done for the month. On Saturday, November 30, the company launched twice more in a little more than three hours. The payloads were more Starlink Internet satellites in addition to two Starshield satellites—a custom version of Starlink for the US Department of Defense—for the US military.

It should have been a routine mission to ferry about three tons of food, fuel, and supplies to the International Space Station, but when Russian cosmonauts opened the hatch to a cargo spacecraft on Saturday, they got a surprise—a toxic smell.

"After opening the Progress spacecraft's hatch, the Roscosmos cosmonauts noticed an unexpected odor and observed small droplets, prompting the crew to close the Poisk hatch to the rest of the Russian segment," NASA said in a statement on Sunday.

According to the space agency, air scrubbers and contaminant sensors on board the orbiting laboratory monitored the station’s atmosphere following the observation of the aberrant smell. By Sunday, flight controllers in Mission Control in Houston determined air quality inside the space station was at normal levels.

It would be easy to be cynical about a German-French startup named The Exploration Company, which aims to build an increasingly sophisticated lineup of spaceships that could one day launch astronauts into orbit.

After all, European space startups don't have the greatest track record, and even with billions of dollars, one of the world's leading aerospace companies, Boeing, has failed so far to deliver a fully space-worthy human vehicle. Space is hard; human spaceflight is harder. So when a European startup shows up with grandiose plans, one's natural inclination might be to dismiss them.

That's more or less how I felt before I spoke with the founder of The Exploration Company, Hélène Huby, this week. She was surprisingly frank about the difficulties in pulling this off and shrewd about her political assessment of why now might just be the time for a new generation of European spacecraft.

Welcome to Edition 7.20 of the Rocket Report! This is a super-long version of the newsletter because we did not publish last week, and there is just a ton of launch news of late. Also, I want to note that next week's report will appear a day early, on Wednesday, due to the Thanksgiving holiday. Speaking of which, you all have our thanks for reading and sharing the Rocket Report with others.

On a completely unrelated note, Rocket Lab has had some amazing mission names over the years. But this weekend's "Ice AIS Baby" launch is probably the best. I always appreciate their effort to find non-vanilla names and find a way to stop, collaborate, and listen.

A day after SpaceX launched its Starship rocket for the sixth time, the company received good news from the Federal Aviation Administration regarding future launch operations from its Starbase facility in South Texas.

In a draft version of what is known as an "Environmental Assessment," the FAA indicated that it will grant SpaceX permission to increase the number of Starship launches in South Texas to 25 per year from the current limit of five. Additionally, the company will likely be allowed to continue increasing the size and power of the Super Heavy booster stage and Starship upper stage.

"FAA has concluded that the modification of SpaceX’s existing vehicle operator license for Starship/Super Heavy operations conforms to the prior environmental documentation, consistent with the data contained in the 2022 PEA, that there are no significant environmental changes, and all pertinent conditions and requirements of the prior approval have been met or will be met in the current action," the federal agency stated in its conclusion.

As SpaceX made its final preparations for the sixth launch of its Starship rocket, the company's chief operating officer and president spoke at a financial conference on Friday about various topics, including the future of the massive rocket and the Starlink satellite system.

The Starship launch system is about to reach a tipping point, Gwynne Shotwell said, as it moves from an experimental rocket toward operational missions.

"We just passed 400 launches on Falcon, and I would not be surprised if we fly 400 Starship launches in the next four years," Shotwell said at the Baron Investment Conference in New York City. "We want to fly it a lot."

A 7-year-old launch company that has yet to have a rocket successfully lift off announced a radical pivot on Thursday. Its new plan? Focusing on missile defense.

The founder and president of ABL Space Systems, Dan Piemont, announced the decision on LinkedIn, adding, "We're consolidating our operational footprint and parting ways with some talented members of our team." He said companies interested in hiring great people in Los Angeles or Mojave, California, should reach out.

A bright beginning

With a background in economics and physics, Piemont founded ABL in 2017 with the aim of developing a ship-and-shoot rocket. The idea was to set up mobile ground systems in remote locations on short notice and launch on demand for the US military and other customers.

Barely nine months after the last cut, NASA's Jet Propulsion Laboratory will again reduce its workforce. On Wednesday, the lab will lay 325 employees off, representing about 5 percent of the workforce at the California-based laboratory that leads the development of robotic space probes for NASA.

"This is a message I had hoped not to have to write," JPL Director Laurie Leshin said in a memo to staff members on Tuesday morning, local time. "Despite this being incredibly difficult for our community, this number is lower than projected a few months ago thanks in part to the hard work of so many people across JPL."

The cuts this week follow a reduction of 530 employees in February of this year due to various factors, including a pause in funding for the Mars Sample Return mission. The NASA laboratory has now cut about one-eighth of its workforce this year.

Like a lot of competitors in the global launch industry, Russia for a long time dismissed the prospects of a reusable first stage for a rocket.

As late as 2016, an official with the Russian agency that develops strategy for the country's main space corporation, Roscosmos, concluded, "The economic feasibility of reusable launch systems is not obvious." In the dismissal of the landing prospects of SpaceX's Falcon 9 rocket, Russian officials were not alone. Throughout the 2010s, competitors including space agencies in Europe and Japan, and US-based United Launch Alliance, all decided to develop expendable rockets.

However, by 2017, when SpaceX re-flew a Falcon 9 rocket for the first time, the writing was on the wall. "This is a very important step, we sincerely congratulate our colleague on this achievement," then-Roscosmos CEO Igor Komarov said at the time. He even spoke of developing reusable components, such as rocket engines capable of multiple firings.

The global space community awoke to a new reality on Wednesday morning.

The founder of this century's most innovative space company, Elon Musk, successfully used his fortune, time, and energy to help elect Donald Trump to president of the United States. Already, Musk was the dominant Western player in space. SpaceX launches national security satellites and NASA astronauts and operates a megaconstellation. He controls the machines that provide essential space services to NASA and the US military. And now, thanks to his gamble on backing Trump, Musk has strong-armed himself into Trump's inner circle.

Although he may not have a cabinet-appointed position, Musk will have a broad portfolio in the new administration for as long as his relations with Trump remain positive. This gives Musk extraordinary power over a number of areas, including spaceflight. Already this week, he has been soliciting ideas and input from colleagues. The New York Times reported that Musk has advised Trump to hire key employees from SpaceX into his administration, including at the Department of Defense. This reflects the huge conflict of interest that Musk will face when it comes to space policy. His actions could significantly benefit SpaceX, of which he is the majority owner and has the final say in major decisions.

Less than a month has passed since the historic fifth flight of SpaceX's Starship, during which the company caught the booster with mechanical arms back at the launch pad in Texas. Now, another test flight could come as soon as Nov. 18, the company announced Wednesday.

The improbable but successful recovery of the Starship first stage with "chopsticks" last month, and the on-target splashdown of the Starship upper stage halfway around the world, allowed SpaceX to avoid an anomaly investigation by the Federal Aviation Administration. Thus, the company was able to press ahead on a sixth test flight if it flew a similar profile.

And that's what SpaceX plans to do, albeit with some notable additions to the flight plan.

A Cargo Dragon spacecraft docked to the International Space Station on Tuesday morning, less than a day after lifting off from Florida.

As space missions go, this one was fairly routine, ferrying about 6,000 pounds (2,700 kg) of cargo and science experiments to the space station. Over the course of nearly a dozen years, this was the 31st cargo supply mission that SpaceX has flown for NASA to the orbiting laboratory.

However, there is one characteristic of this flight that may prove significant for NASA and the future of the space station. As early as Friday, NASA and SpaceX have scheduled a "reboost and attitude control demonstration," during which the Dragon spacecraft will use some of the thrusters at the base of the capsule. This is the first time the Dragon spacecraft will be used to move the space station.

When Chinese space officials unveiled the design for the country's first super heavy lift rocket nearly a decade ago, it looked like a fairly conventional booster. The rocket was fully expendable, with three stages and solid motors strapped onto its sides.

Since then, the Asian country has been revising the design of this rocket, named Long March 9, in response to the development of reusable rockets by SpaceX. As of two years ago, China had recalibrated the design to have a reusable first stage.

Now, based on information released at a major airshow in Zhuhai, China, the design has morphed again. And this time, the plan for the Long March 9 rocket looks almost exactly like a clone of SpaceX's Starship rocket.

Boeing's Starliner spacecraft safely landed empty in the New Mexico desert about eight weeks ago, marking a hollow end to the company's historic first human spaceflight. The vehicle's passengers during its upward flight to the International Space Station earlier this summer, Butch Wilmore and Suni Williams, remain in space, awaiting a ride home on SpaceX's Crew Dragon.

Boeing has been steadfastly silent about the fate of Starliner since then. Two senior officials, including Boeing's leader of human spaceflight, John Shannon, were originally due to attend a post-landing news conference at Johnson Space Center in Houston. However, just minutes before the news conference was to begin, two seats were removed—the Boeing officials were no-shows.

In lieu of speaking publicly, Boeing issued a terse statement early on the morning of September 8, attributing it to Mark Nappi, vice president and program manager of Boeing's commercial crew program. "We will review the data and determine the next steps for the program," Nappi said, in part.
