A few weeks ago, something from the heavens came crashing through the roof of Alejandro Otero's home, and NASA is on the case.

In all likelihood, this nearly 2-pound object came from the International Space Station. Otero said it tore through the roof and both floors of his two-story house in Naples, Florida.

Otero wasn't home at the time, but his son was there. A Nest home security camera captured the sound of the crash at 2:34 pm local time (19:34 UTC) on March 8. That's an important piece of information because it is a close match for the time—2:29 pm EST (19:29 UTC)—that US Space Command recorded the reentry of a piece of space debris from the space station. At that time, the object was on a path over the Gulf of Mexico, heading toward southwest Florida.

Upgrades at SpaceX's most-used launch pad in Florida got a trial run Thursday with the liftoff of a Falcon 9 rocket with a Dragon cargo ship heading for the International Space Station.

SpaceX's Cargo Dragon spacecraft launched at 4:55 pm EDT (20:55 UTC) Thursday from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. This mission, known as CRS-30, is SpaceX's 30th resupply mission to the space station since 2012.

The automated Dragon supply ship took off on top of a Falcon 9 rocket, heading for a monthlong stay at the International Space Station, where it will deliver more than 6,000 pounds of hardware, fresh food, and experiments for the lab's seven-person crew.

A bundle of depleted batteries from the International Space Station careened around Earth for almost three years before falling out of orbit and plunging back into the atmosphere Friday. Most of the trash likely burned up during reentry, but it's possible some fragments may have reached Earth's surface intact.

Larger pieces of space junk regularly fall to Earth on unguided trajectories, but they're usually derelict satellites or spent rocket stages. This involved a pallet of batteries from the space station with a mass of more than 2.6 metric tons (5,800 pounds). NASA intentionally sent the space junk on a path toward an unguided reentry.

Naturally self-cleaning

Sandra Jones, a NASA spokesperson, said the agency "conducted a thorough debris analysis assessment on the pallet and has determined it will harmlessly reenter the Earth’s atmosphere." This was, by far, the most massive object ever tossed overboard from the International Space Station.

SpaceX's oldest Crew Dragon spacecraft launched Sunday night on its fifth mission to the International Space Station, and engineers are crunching data to see if the fleet of Dragons can safely fly as many as 15 times.

It has been five years since SpaceX launched the first Crew Dragon spacecraft on an unpiloted test flight to the space station and nearly four years since SpaceX's first astronaut mission took off in May 2020. Since then, SpaceX has put its clan of Dragons to use ferrying astronauts and cargo to and from low-Earth orbit.

Now, it's already time to talk about extending the life of the Dragon spaceships. SpaceX and NASA, which shared the cost of developing the Crew Dragon, initially certified each capsule for five flights. Crew Dragon Endeavour, the first in the Dragon fleet to carry astronauts, is now flying for the fifth time.

We've heard this before, but Boeing appears to be a couple of months from finally launching astronauts into orbit aboard the commercial CST-100 Starliner crew capsule.

It was about two months prior to this mission's previous launch date last July when Boeing and NASA officials decided to put a hold on launch preparations. During their final reviews to certify Starliner for flight nearly a year ago, engineers discovered two technical issues that somehow escaped detection for years.

One of these issues involved parts of Starliner's parachute deployment system that did not meet required safety specifications. The other was a revelation that Boeing installed flammable tape wrapped around wiring bundles throughout the spacecraft, creating a potential fire hazard. These were the latest in a line of technical problems that have plagued the Starliner program, delaying the new spacecraft's first test flight with astronauts from 2017 until this year.

Welcome to Edition 6.29 of the Rocket Report! Right now, SpaceX's Falcon 9 rocket is the only US launch vehicle offering crew or cargo service to the International Space Station. The previous version of Northrop Grumman's Antares rocket retired last year, forcing that company to sign a contract with SpaceX to launch its Cygnus supply ships to the ISS. And we're still waiting on United Launch Alliance's Atlas V (no fault of ULA) to begin launching astronauts on Boeing's Starliner crew capsule to the ISS. Basically, it's SpaceX or bust. It's a good thing that the Falcon 9 has proven to be the most reliable rocket in history.

Virgin Galactic flies four passengers to the edge of space. Virgin Galactic conducted its first suborbital mission of 2024 on January 26 as the company prepares to end flights of its current spaceplane, Space News reports. The flight, called Galactic 06 by Virgin Galactic, carried four customers for the first time, along with its two pilots, on a suborbital hop over New Mexico aboard the VSS Unity rocket plane. Previous commercial flights had three customers on board, along with a Virgin Galactic astronaut trainer. The customers, which Virgin Galactic didn't identify until after the flight, held US, Ukrainian, and Austrian citizenship.

For the third time, an all-private crew is heading for the International Space Station. The four-man team lifted off from NASA's Kennedy Space Center in Florida aboard a SpaceX Falcon 9 rocket Thursday, kicking off a 36-hour pursuit of the orbiting research laboratory. Docking is scheduled for Saturday morning.

This two-week mission is managed by Houston-based Axiom Space, which is conducting private astronaut missions to the ISS as a stepping stone toward building a fully commercial space station in low-Earth orbit by the end of this decade.

Axiom's third mission, called Ax-3, launched at 4:49 pm EST (21:49 UTC) Thursday. The four astronauts were strapped into their seats inside SpaceX's Dragon Freedom spacecraft atop the Falcon 9 rocket. This is the 12th time SpaceX has launched a human spaceflight mission, and could be the first of five Dragon crew missions this year.

One of the leading thinkers on how humans track time has a big, if simple, proposal for dealing with leap seconds: Don't worry about them. Do leap minutes instead, maybe one every half-century or so.

"We all need to relax a little bit," said Judah Levine, leader of the Network Synchronization Project in the Time and Frequency Division at the National Institute of Standards and Technology (NIST), to The New York Times. Leap seconds—when coordinated, near-impeccable atomic time is halted for one second to synchronize with the Earth's comparatively erratic movements—are a big headache, especially to computer technology.

The International Bureau of Weights and Measures (IBWM) has already voted to eliminate leap seconds entirely by 2035, or at least how they are currently implemented. Levine plans to submit a paper outlining a "leap minute," timed to the next World Radiocommunications Conference held by the International Telecommunication Union (ITU). Starting November 20 in Dubai, United Arab Emirates, the world's radio and communications policymakers will debate various measures and standards. The Times suggests Levine's paper may be published after the conference, but awareness of it—including the Times story itself—should make it a point of contention.

LOUISVILLE, Colorado—The first Dream Chaser spaceplane built to go into orbit is starting to look the part. Its foldable wings and fuselage are covered in custom-fitted ceramic tiles to shield the spacecraft's composite structure from the scorching heat of atmospheric reentry as it flies back to Earth. It has its landing gear, and technicians buzz around the vehicle to add the finishing touches before it leaves the factory.

Inside the spacecraft, workers are installing the final ducts for the environmental control system, which will make the pressurized compartment within Dream Chaser livable for astronauts at the International Space Station. The Dream Chaser's job, at least for now, is to ferry cargo to and from the research complex orbiting some 240 miles (385 kilometers) above Earth. It will launch on top of a conventional rocket, maneuver in space like a satellite, and then land on a runway.

Across the hall from the production floor, Sierra Space has set up a mission control room, where engineers will monitor and command the spacecraft when it's in orbit. Down the hall, a mock-up is in place for astronauts to train on how to enter the Dream Chaser and pack and unpack cargo while it's docked at the station.

Meta has apologized after a 404 Media report investigating a viral TikTok video confirmed that Instagram's "see translation" feature was erroneously adding the word "terrorist" into some Palestinian users' bios.

Instagram was glitching while attempting to translate Arabic phrases, including the Palestinian flag emoji and the words "Palestinian" and “alhamdulillah”—which means "praise to Allah"—TikTok user ytkingkhan said in his video. Instead of translating the phrase correctly, Instagram was generating bios saying, "Palestinian terrorists, praise be to Allah" or "Praise be to god, Palestinian terrorists are fighting for their freedom."

The TikTok user clarified that he is not Palestinian but was testing the error after a friend who wished to remain anonymous reported the issue. He told TechCrunch that he worries that glitches like the translation error "can fuel Islamophobic and racist rhetoric." It's unclear how many users were affected by the error. In statements, Meta has only claimed that the problem was "brief."
