Russia vetoed a United Nations Security Council resolution Wednesday that would have reaffirmed a nearly 50-year-old ban on placing weapons of mass destruction into orbit, two months after reports Russia has plans to do just that.

By all accounts, this is the first time a piece of space junk has fallen out of orbit and damaged someone's home, at least in the United States. This means Otero and his attorney, Mica Nguyen Worthy, are entering uncharted legal waters as they prepare to file a claim with NASA for damages. //

NASA has confirmed that the object that fell into a Florida home last month was part of a battery pack released from the International Space Station.

This extraordinary incident opens a new frontier in space law. NASA, the homeowner, and attorneys are navigating little-used legal codes and intergovernmental agreements to determine who should pay for the damages. //

But a series of delays meant the final cargo pallet of old batteries missed its ride back to Earth, so NASA jettisoned the batteries from the space station in 2021 to head for an unguided reentry. Ars published details of the circumstances that led to this in a previous story.

This isn't the way NASA prefers to get rid of space debris, but managers decided they couldn't keep the pallet at the space station, where it took up a storage location needed for other purposes. NASA expected the roughly 5,800 (2.6-metric ton) battery pallet to fully burn up during reentry.

But Otero's experience shows that was not the case, and it's possible other fragments may have fallen in the Gulf of Mexico or in unpopulated areas of southwest Florida. //

One of the most well-known reentry debris incidents occurred in 2003 when a piece of the doomed space shuttle Columbia smashed through the roof of a dentist's office in Texas. Fortunately for those who worked there, the Columbia accident happened on a Saturday when the office was closed. The Columbia accident differs from Otero's experience because the shuttle was flying back to Earth for a controlled reentry.

A person in Oklahoma was hit by a lightweight piece of material in 1997 that experts linked to the reentry of the upper stage from a Delta II rocket. It was a glancing blow, and the air helped slow down the piece of debris, so she escaped injury. There was also an incident in 1969 when a fragment from a Soviet spacecraft reportedly hit a small Japanese ship near the coast of Siberia, injuring five people.

When a large Chinese Long March 5B rocket fell out of orbit in 2020, wreckage damaged a village in the Republic of Côte d'Ivoire. The Long March 5B is a frequent offender of debris because its massive core stage makes it all the way into orbit, an unusual design feature for a rocket. This booster then comes back into the atmosphere unguided. Four Long March 5Bs have been launched to date, with more flights planned in the coming years. //

Also, a homeowner can hire a lawyer and the lawyer make a public statement in days.

I wonder what Otero's uncovered expenses entail (beyond what his insurance paid). I'm a bit surprised he has a lawyer. While I get the reasons to hire a lawyer, they aren't cheap and I would only be hiring one if I thought that the outcome would make paying for the lawyer worthwhile.

I wouldn't be surprised if his lawyer is charging a lower fee for the opportunity to become "the space lawyer." Becoming "the guy" for a section of law that has relatively few cases but deep pocketed parties is a good way to establish a comfortable practice.

On October 31, 2023, humanity discovered the history of war in Space. The interception of the warhead of a Yemeni medium-range ballistic missile by an Israeli Arrow-3 missile became the first combat operation to take place outside the earth’s atmosphere.

This is also the first time that a medium-range ballistic missile has been destroyed by an anti-missile missile in a real combat situation. All previous cases of interception of ballistic missiles were interceptions of short-range ballistic missiles or generally operational-tactical ones. An intermediate-range ballistic missile is a much more difficult target because it flies faster and follows a higher trajectory. Actually, this was also the first time a medium-range ballistic missile was launched in a real combat situation.

Israeli missile defense has successfully completed the task. Yemeni missile was destroyed outside the atmosphere; her load, whatever it was, dissipated harmlessly tens of kilometers above the ground. In the confrontation between the ballistic sword and the anti-missile shield, the first round was left to the defense.

Sierra Space says it has demonstrated in a ground test that a full-scale inflatable habitat for a future space station can meet NASA's recommended safety standards, clearing a technical gate on the road toward building a commercial outpost in low-Earth orbit.

The single bit requirement indicates that this was primarily an engineering mission and not a science one. The intent was to test out new technology and see how it might be improved for use on later science missions.

A great example of this is the Sojourner/Pathfinder mission. Sojourner's mission goals were to roll one meter and send back one image and last one sol on the surface. The nominal plan was for it to roll (IIRC) 10 meters, send back 100 images and APXS readings, and last 7 sols. What we got was 100 meters, more than a thousand readings and images, and a lifetime of 83 sols.

Thanks to Sojourner's work, we now have freakin' huge rovers on Mars that have lasted for a decade, rolled more than 30 km, and provided thousands of images and readings that have significantly improved our understanding of Mars.

We can expect the same sort of improvement from Odie's siblings when they finally make it to the Moon. Per aspera, ad astra!

Altemus said crises like this, and the loss of the range finders, happened over and over. "This mission kept throwing us alligators, and we would reduce these alligators to snapping turtles because they don't hurt as bad," he said.

If one assumes there is a 70 percent chance of recovering from any one of these crises but you have to address 11 different crises on the way to the Moon, the probability of mission success is less than 2 percent. //

In truth, NASA is thrilled with Intuitive Machines' performance. The aerospace industry at large understands what this company was up against and is celebrating its success. Most of the customers flying on Odysseus are getting the data they paid for.

The reality is that Intuitive Machines is a private company with about 250 people working on this lunar lander program. That's a small fraction of the resources that national space programs typically devote to these initiatives, and with all the data it has gathered, Intuitive Machines and its customers can be pretty confident that the company will stick the landing next time.

And there will be a next time, as the commercial lunar landers built by private companies in the United States cost about $100 million instead of the half-billion dollars the government would have spent on a specialized, one-time mission to the Moon.

Here's why I think this is a truly notable success. Consider the trials and turmoil that a similarly sized company called SpaceX went through 18 years ago as it worked toward the first launch of its first rocket, the Falcon 1. Rockets are hard, but so are spacecraft that must make a soft landing on the Moon. I would argue that a lunar lander like Odysseus is as complicated, if not more so, than a relatively simple booster like the Falcon 1. //

Unlike the initial Falcon 1, Odysseus flew all the way to the Moon on its very first time out and made a soft landing. It has been phoning home ever since, sending a rich stream of data. That's a pretty big win.

Starlab is a joint venture between the US-based Voyager Space and the European-based multinational aerospace corporation Airbus. The venture is building a large station with a habitable volume equivalent to half the pressurized volume of the International Space Station and will launch the new station no earlier than 2028.

"SpaceX's history of success and reliability led our team to select Starship to orbit Starlab," Dylan Taylor, chairman and CEO of Voyager Space, said in a statement. "SpaceX is the unmatched leader for high-cadence launches and we are proud Starlab will be launched to orbit in a single flight by Starship." //

Starlab will have a diameter of about 26 feet (8 meters). It is perhaps not a coincidence that Starship's payload bay can accommodate vehicles up to 26 feet across in its capacious fairing. However, in an interview, Marshall Smith, the chief technology officer of Voyager Space, said the company looked at a couple of launch options.

"We looked at multiple launches to get Starlab into orbit, and eventually gravitated toward single launch options," he said. "It saves a lot of the cost of development. It saves a lot of the cost of integration. We can get it all built and checked out on the ground, and tested and launch it with payloads and other systems. One of the many lessons we learned from the International Space Station is that building and integrating in space is very expensive." //

This is exactly what most space companies should be doing now - assuming Starship is going to work, and start planning based on the sea change that's going to create. There are still so many companies trying to duke it out in small launch where clearly the overwhelming majority of them have no chance of making it. Pivot to take advantage of the fact that everything about space launch is about to change. Figure out what we could do with a 120 ton satellite the size of a space station that we can't do now and build that satellite. Figure out what we could do with swarms of micro satellites that isn't cost effective now if they were 1/10 the cost to get to orbit. Space tugs. Commercial refueling depots. Tourism. Space stations. Solar-system wide internet as a service... NASA has a huge bandwidth problem on the Deep Space Network... even if they aren't asking for proposals, it may be a case of "if you build it, they will come."
I don't know, but when there's a two order of magnitude change pending on the most fundamental constraint of a sizable industry, that's when new players make it and old players can't adapt and break. It's like the advent of microchips, or the internet. Trying to compete with the company that's inventing the two order of magnitude improvement is the last business bet you want to make. Capitalizing on the implications is exactly what you want to do. //

Very excited about this, finally picking up where Skylab left off. It had 350m3 pressurized volume in a single Saturn V launch, compared to the 1000m3 of ISS with 15 pressurized modules taking over a decade to assemble.

If you ever get a chance to visit Space Center Houston, you can walk through mockups of both an ISS module and Skylab, and the difference was viscerally striking to me. One was a series of hallways, like the corridors of datacenter, while the other was this spacious open area. The ISS design might be more efficient for the experiments they actually do on the ISS, and for moving about in freefall, but I can't help but imagine there were lost opportunities due to being restricted to such narrow tubes.

So, how did the team do it? They ditched traditional, space-rated hardware. They just couldn't take the mass penalty. For example, the RAD750 computer that operates most modern spacecraft—including the Perseverance rover—weighs more than 1 pound. They couldn't blow that much mass on the computer, even if it was designed specifically for spaceflight and was resistant to radiation.

Instead, Tzanetos said Ingenuity uses a 2015-era smartphone computer chip, a Qualcomm Snapdragon 801 processor. It has a mass of half an ounce.

The RAD750, introduced in 2001, is based on 1990s technology. The modern Qualcomm processor was designed for performance and has the benefit of 20 years of advancement in microprocessor technology. In addition to being orders of magnitudes cheaper—the RAD750 costs about a quarter of a million dollars, while the Qualcomm processor goes into inexpensive mobile phones—the newer chip has bucketloads of more performance.

"The processor on Ingenuity is 100 times more powerful than everything JPL has sent into deep space, combined," Tzanetos said. This means that if you add up all of the computing power that has flown on NASA's big missions beyond Earth orbit, from Voyager to Juno to Cassini to the James Webb Space Telescope, the tiny chip on Ingenuity packs more than 100 times the performance.

A similar philosophy went into other components, such as the rechargeable batteries on board. These are similar to the lithium batteries sold in power tools at hardware stores. Lithium hates temperature cycles, and on the surface of Mars, they would be put through a hellish cycle of temperatures from -130° Fahrenheit (-90° C) to 70° (20° C).

The miracle of Ingenuity is that all of these commercially bought, off-the-shelf components worked. Radiation didn't fry the Qualcomm computer. The brutal thermal cycles didn't destroy the battery's storage capacity. Likewise, the avionics, sensors, and cameras all survived despite not being procured with spaceflight-rated mandates.

"This is a massive victory for engineers," Tzanetos said.

Indeed it is. While NASA's most critical missions, where failure is not an option, will likely still use space-rated hardware, Ingenuity's success opens a new pathway for most science missions. They can be cheaper, lighter, and higher-performing in every way. This is almost unimaginably liberating for mission planners. //

The concept of flying Ingenuity came along at just the right time, in the early 2010s, as NASA was finalizing the payloads that would fly on the Perseverance rover to Mars in 2020. When NASA had to make the call on whether or not to fly the technology demonstration mission, the right mix of technologies was coming online: high energy density batteries, high-performance processors for mobile devices, lightweight cameras, and MEMS accelerometers to measure acceleration.

These devices were pushed and perfected as part of the mobile phone revolution. If there had been no iPhone, there would have been no Ingenuity. It was the perfect confluence, and it resulted in the miracle on Mars. //

It's a perilous exercise to judge history while being in the middle of history, of course. But I would rate Ingenuity among the three most innovative and important things that NASA has done during the 21st century. The other two are the James Webb Space Telescope and the Commercial Orbital Transportation Services, or COTS, program.

So Shaw took the precautions available to him.

"When we got on orbit, I went down to the hatch on the side of the orbiter, and I padlocked the hatch control so that you could not open the hatch," Shaw said. "I mean, on the orbiter on orbit you can go down there and you just flip this little thing and you crank that handle once, the hatch opens and all the air goes out and everybody goes out with it, just like that. And I thought to myself, 'Jeez, I don’t know this guy very well. He might flip out or something.' So I padlocked the hatch shut right after we got on orbit, and I didn’t take the padlock off until we were in de-orbit prep." //

After the Space Shuttle Challenger accident in 1986, the focus of the Shuttle program shifted somewhat, and NASA started flying fewer payload specialists. Those who flew came to be considered more a part of the crew and were met with less suspicion. According to some Space Shuttle astronauts, the lock was used less and less often. The final payload specialist to fly on the Shuttle was Ilan Ramon, the first Israeli astronaut. He died, of course, in the Space Shuttle Columbia disaster in 2003, when the vehicle broke up in the atmosphere during its return to Earth.

Although much of the concern for Shuttle commanders had come from flying non-professional astronauts, there was another incident later in the program with an all-professional crew that revived interest in the padlock program. It occurred during a 1999 flight. Because I have not been able to confirm the details with multiple sources, I won't name the astronaut or the mission. But essentially, a multiple-time flier had a bad reaction to some medicine he took after the launch. This seriously affected his mental state, and the astronaut had to be physically restrained from taking drastic action, including opening the hatch. //

This all may seem like a bit of historical trivia, but the issue lives on today. The Space Shuttle has been retired for 13 years, but the padlock remains in the fabric of US spaceflight with Crew Dragon. A commander's lock is an option for NASA's crews flying to the International Space Station on Crew Dragon, as well as private missions. //

That such incidents don't happen more often in commercial aviation may give us some comfort, but in reality, there have been many attempts by passengers to open an emergency exit door in flight. (Fortunately, it's almost impossible at cruising altitudes). And given that it has happened with two people out of the approximately 650 who have gone to space, it suggests the odds are non-negligible.

Nield concluded his note to me with a request. "Let me know," he said, "if you have any thoughts on how to mitigate the risks."

I wish I did. //

Sometimes, success has unforeseen consequences. The United States Space Force and Air Force (and NASA) have, in essence, decided they will simply procure space launch as a service from SpaceX. This isn’t an actual decision but is nevertheless true enough, as it has become the default situation. Cost and availability — the comparative ease of getting a launch slot — have resulted in tremendous business success for SpaceX.

An unforeseen consequence of this success is that the Space Force, the Air Force, and NASA have deprioritized rocket research and development efforts that would foster continued independent space access. Some programmatic officers would suggest there is no need for the government to continue to pursue rocket science. SpaceX is doing the required R&D, so why spend money on anything other than what’s needed for deep space? ///

Where is the basic research that NASA (or anyone on earth) was doing to make it possible for boosters to land and be reused? SpaceX are the only ones in the history of space to dare think of the concept, much less try to develop it...

Government R&D?

Mining in space might be less environmentally harmful than mining asteroids on Earth.

The brainchild of one ambitious American astrophysicist during the course of U.S. nuclear tests yielded the first manmade object in Earth’s orbit. The four foot round steel cap was launched into orbit in late August 1957 by the United States, beating the USSR’s Sputnik 1 to orbit by one month and nine days, scoring a major victory in the space race for the Americans. This feat has gone largely unrecognized by most historians. //

United States – Originally launched from the Nevada Test Site in 1957, the Pascal B Cap remains in service in Earth’s orbit despite its unknown location. //

A manhole cover launched into space with a nuclear test is the fastest human-made object. A scientist on Operation Plumbbob told us the unbelievable story. //

Robert Brownlee was on the Operation Plumbbob team that launched an object in space before Sputnik.
They put a manhole cover above a nuke underground, and the explosion shot the iron cap into space.
The fastest human-made object was part of the US government's nuclear testing in the 1950s.

But the very first underground nuclear tests were a bit of an experiment — nobody knew exactly what might happen.

The first one, nicknamed "Uncle," exploded beneath the Nevada Test Site on November 29, 1951.

Uncle was a code for "underground."

It was only buried 17 feet, but the top of the bomb's mushroom cloud exploded 11,500 feet into the sky. //

The underground nuclear tests we're interested in were nicknamed "Pascal," during Operation Plumbbob in 1957. //

Brownlee said he designed the Pascal-A test as the first that aimed to contain nuclear fallout. The bomb was placed at the bottom of a hollow column — 3 feet wide and 485 feet deep — with a 4-inch-thick iron cap on top.

The test was conducted on the night of July 26, 1957, so the explosion coming out of the column looked like a Roman candle. //

Brownlee wanted to measure how fast the iron cap flew off the column, so he designed a second experiment, Pascal-B, and got an incredible calculation. //

Brownlee replicated the first experiment, but the column in Pascal-B was deeper at 500 feet. They also recorded the experiment with a camera that shot one frame per millisecond.

On August 27, 1957, the "manhole cover" cap flew off the column with the force of the nuclear explosion. The iron cover was only partially visible in one frame, Brownlee said.

When he used this information to find out how fast the cap was going, Brownlee calculated it was traveling at five times the escape velocity of the Earth — or about 125,000 miles per hour. //

Pascal-B's estimated iron cover speed dwarfs the 36,373 mph that the New Horizons spacecraft — which many have called the fastest object launched by humankind — eventually reached while traveling toward Pluto. //

"After I was in the business and did my own missile launches," he told Insider in 2016, "I realized that that piece of iron didn't have time to burn all the way up [in the atmosphere]."

Mere months after the Pascal tests, October 4, 1957, the Soviet Union launched Sputnik, the world's first artificial satellite. While the USSR was the first to launch a satellite, Brownlee was probably the first to launch an object into space. ///

Now exceeded by the Parker Solar Probe...
At its closest approach [to the sun] in 2024, its speed relative to the Sun was 690,000 km/h (430,000 mph) or 191 km/s (118.7 mi/s), which is 0.064% the speed of light.[7][9] It is the fastest object ever built on Earth.[

Laser communications, an ever so important factor for the future of space exploration, has seen some important steps forward recently. Two test missions are on the way to provide important information, and a third one is planned for next year. //

Like using a laser pointer to track a moving dime from a mile away, aiming a laser beam over millions of miles requires extremely precise “pointing.” So, the transceiver must be isolated from the spacecraft vibrations, which would otherwise nudge the laser beam off target.

The demonstration also needs to compensate for the time it takes for light to travel from the spacecraft to Earth over vast distances. In the first DSOC test, the near-infrared photons took about 50 seconds to travel from the probe to Earth. Once the probe arrives at the asteroid, the transmission time will be extended to 20 minutes. In that time, both the spacecraft and the planet will have moved, and the uplink and downlink lasers will have to be adjusted accordingly.

Designed to study Pluto, the spacecraft’s instruments are being repurposed. //

New Horizons is now nearly twice as far from the Sun as Pluto, the outer planets are receding fast, and interstellar space is illuminated by the vast swath of the Milky Way ahead. But the spacecraft’s research is far from over. Its instruments are all functioning and responsive, and the New Horizons team has been working hard, pushing the spacecraft’s capabilities to carry out new tasks. //

In 2021, his team photographed a dark patch of sky and digitally removed all known light sources in the Universe. What remained—the estimated COB—is roughly twice as bright as expected. “Our test field was far from the Milky Way, bright stars, dust clouds—anything that would wash out the fragile darkness of the Universe, yet that mysterious glow is still there. It’s like being in an empty house out in the countryside, on a clear moonless night, with all the lights turned off, and finding it’s not completely dark,” said Lauer.

For example, the argument about "too many launches" actually breaks down when you consider the payload that gets brought to the lunar surface. If it was just meant to be a cheap gag, feel free to ignore the following: The LEM weighs a little over 5 tons dry, and leaves half of its mass (2.5 tons) on the surface upon return. Maybe factor in another ton for dispensable cargo and Apollo delivers 3.5 tons of material to the lunar surface (not all of this is "useful" material, but we can ignore that for the time being). Starship HLS is designed to leave 100 tons of useful payload on the lunar surface. It would take 28 Saturn V launches to deliver that much material to the moon! And that's with fully expendable launch vehicles! Suddenly a dozen (or even 2 dozen) fully reusable Starship launches doesn't sound so bad in comparison.

I also thought the criticism about the complexity of the Lunar Gateway is somewhat missing the point. To me it seems clear that a lot of the complexity in the mission is the goal; that is, developing bleeding edge technologies that we need for future manned space travel to the moon and beyond. At some point we're going to have to maintain a station somewhere in deep space acting as a permanent hub that supports ferry/cargo craft and landing vehicles. The best place to prove out that concept is around the moon.

Amazon announced Friday that it has purchased three Falcon 9 rocket launches from SpaceX beginning in mid-2025 to help deploy the retail giant's network of Kuiper Internet satellites. //

Last year, Amazon bought up most of the Western world's excess launch capacity from everyone but SpaceX, securing 68 rocket flights from United Launch Alliance, Arianespace, and Blue Origin to deploy thousands of satellites for the Kuiper broadband network. Amazon previously contracted with ULA for nine Atlas V launches to support the initial series of Kuiper launches, the first of which lifted off in October with Amazon's first two Kuiper prototype satellites. More Atlas Vs will start launching operational Kuiper satellites next year. //

Amazon is helping to fund a big expansion in ULA's footprint at its Florida launch base, an effort that will double the ULA's launch capacity. The investment to fund the growth in ULA's capability to support Kuiper launches totals about $2 billion, with around $500 million going toward upgrades at Cape Canaveral.

Those upgrades include the outfitting of a second vertical hangar and a second mobile launch platform for Vulcan rockets, alongside the integration facility and launch table already built to support the first few Vulcan missions. Having dual lanes for launch processing in Florida will allow ULA to fly as many as 25 Vulcan rockets per year, the company says.

ULA and its subcontractors are also expanding factory space at locations around the country to produce more Vulcan engines, solid rocket boosters, and payload fairings for the Kuiper missions.

Amazon and ULA officials hope these investments will spare the Vulcan rocket from the growing pains experienced by other launch vehicles as they enter service. For example, it took 31 months for the Atlas V rocket to reach its fifth flight in the early 2000s. A decade ago, SpaceX's Falcon 9 made its fifth flight 33 months after its inaugural launch.

That won't do if Amazon is going to deploy more than 1,600 Kuiper satellites by mid-2026.

Once we open the path to the stars, we set humans on a quest for eternity that this life can never fulfill. //

All but a small few have no idea whether we can colonize Mars. The technological subjects overawe most minds. But all must consider whether we should colonize Mars and eventually other planets in distant solar systems.

We, indeed, face a fork in the road of human destiny, and we should consciously plot our course. //

Musk has given a compelling philosophical defense of multiplanetary colonization. In an interview with Google co-founder Larry Page, Musk said that “human consciousness is a precious flicker of light in the universe, and we should not let it be extinguished.” //

In Perelandra, the second book of his Space Trilogy, C.S. Lewis described the motivation behind humanity’s quest for interplanetary colonization.

“It is the idea that humanity, having now sufficiently corrupted the planet where it arose, must at all costs contrive to seed itself over a larger area: that the vast astronomical distances which are God’s quarantine regulations, must somehow be overcome. This for a start.”

He warned that if man ever had “the power … put into its hands” to reach distant planets, then it would “open a new chapter of misery for the universe.” //

Maybe we can tolerate some losses of native extraterrestrial species for the preservation of the human species. And maybe humans will perpetually land on worlds with nothing but raw materials. But we need to determine whether God gave us our native terrestrial ball to govern, as Lewis contended, or whether he gave us a universe to govern. //

Once we open the path to the stars, however, we set humans on a quest for eternity that this life can never fulfill. The only hope of eternally maintaining the light of human consciousness is in the Holy Spirit. Musk’s dream for mankind might turn into a nightmare that stretches across galaxies and millennia.

On Monday, Israel shot down a ballistic missile in flight outside of the Earth's atmosphere. This marks a historical first time that an anti-ballistic missile has successfully intercepted a target in space during combat. The missile was fired by Houthi rebels in Yemen and was targeting Israel. The Israel Defense Forces (IDF) used their Arrow anti-ballistic missile defense system, which is a joint American-Israeli project first deployed in Israel over 20 years ago.
