Northrup Grumman has launched a fresh batch of supplies and equipment to the International Space Station with its Antares rocket and Cygnus spacecraft.

On Saturday, February 19th, an uncrewed Northrup Grumman Cygnus spacecraft lifted off on an Antares rocket from Pad 0A at NASA’s Wallops Flight Facility in northeast Virginia. As part of Northrup Grumman’s 17th Cargo Resupply Services (CRS) mission to the International Space Station since 2013, the rocket successfully carried the Cygnus spacecraft and more than 3.7 tons (~8300 lb) of cargo into orbit.

At 4:44 AM EST Monday, February 21st, Cygnus finished its autonomous rendezvous with the ISS and the station’s robotic Canadarm2 arm – operated by NASA astronaut Raja Chari – grabbed the hovering spacecraft and ultimately installed it on a berthing port later that morning. Prior to its arrival, NASA astronauts Raja Chari and Kayla Barron trained on the US Destiny laboratory module’s robotics workstation to prepare for the capture operation.

On February 22nd, ISS astronauts began the process of unpacking Cygnus, which brought with it an array of supplies, snacks, scientific investigations, and critical materials needed to support over 250 experiments aboard the ISS. That list of experiments includes medical research, technology development, space safety work, and plant life investigations. In one investigation, cancer cells from breast and prostate cancer will be treated with MicroQuin, a novel cancer treatment drug. This investigation will allow tumors to be treated in a microgravity environment, allowing researchers an opportunity to better understand and characterize their structure, gene expression, cell signaling, and response to the treatment.

The NG-17 mission also carried a modification kit that will pave the way for the installation of the new set of upgraded solar arrays. The second batch will be launched no earlier than (NET) May 2022 on SpaceX’s CRS-25 Cargo Dragon 2 spacecraft. Additionally, NASA says that Cygnus NG-17 “[included] other components [needed] for the successful functioning of astronaut life on the space station, such as a trash deployer and acoustic covers for the waste management system.” (NASA)

In general, NG-17 was loaded with:

• 2,980 pounds (1,352 kilograms) of crew supplies

• 2,883 pounds (1,308 kilograms) of [station] hardware

• 1,975 pounds (896 kilograms) of science investigations

• 200 pounds (100 kilograms) of unpressurized cargo

• 132 pounds (60 kilograms) of spacewalk equipment

• 77 pounds (35 kilograms) of computer resources

While attached to the ISS, Cygnus will also be responsible for raising the altitude of the space station for the first time in its history. This will be the first time since the Space Shuttle’s retirement in 2011 that an American spacecraft helps maintain the space station’s orbit – a task Russia has exclusively handled for more than a decade. “This Cygnus vehicle has been modified to [use some of its own propellant] to reboot ISS. We’ve done a test prior to this with Cygnus, but this will be our first real use of this capability to actually re-boost the station. And it gives us another way to do so, in addition to the Russian Zvezda thrusters or the Russian Progress cargo spacecraft capabilities,” stated Dina Contella, NASA’s ISS operations integration manager.

Cygnus will remain attached to the International Space Station for the next three months and is set to depart in May. Once detached from the ISS, the spacecraft – operating a bit like a space tug or orbital transfer vehicle – will deploy a number of cubesats. Finally, the fully expendable spacecraft will dispose several thousand pounds of trash when it reenters and burns up in Earth’s atmosphere later this year.

Tesla Cybertruck production snaps back after ugly supplier fight

Cybertrucks are piling up again at Giga Texas after Tesla’s court win against a parts supplier.

Cybertruck production at Giga Texas is showing its first visible recovery since Tesla sued a supplier last month over withheld manufacturing tooling.

Aerial observer Joe Tegtmeyer flew over the Austin factory Wednesday morning and counted roughly 100 or more Cybertrucks filling the outbound lot, a sharp jump from the thin numbers seen in recent weeks. The flyover came a day after a judge granted Tesla a temporary restraining order against Angstrom Automotive Group, the parts supplier at the center of the dispute.

Tesla filed an emergency lawsuit in late July after Angstrom told the automaker it planned to close the Troy, Texas facility where Tesla’s die-cast tools, trim dies and other Cybertruck stamping equipment were housed. According to Tesla’s complaint, a shipment of 700 finished parts never left the building, and when Tesla sent representatives to retrieve its equipment, accompanied by law enforcement, they were turned away. Angstrom allegedly then asked for an extra $250,000 a week to keep operating, which Tesla’s filing described as holding its own property for ransom.

Tesla quietly made the Cybertruck even stronger

The restraining order gives Tesla immediate right of entry to Angstrom’s facility to recover the tooling. It is temporary, with a fuller hearing still to come, but the speed of Wednesday’s rebound suggests the Angstrom shortage was indeed the main bottleneck limiting Cybertruck output. Outbound lot counts are an imperfect measure of actual production, since finished trucks can sit for days before shipping, but a lot that full after a lean stretch is a meaningful signal.

Cybertruck output at Giga Texas has fluctuated all year as Tesla worked through supply issues and introduced new trims, including a cheaper Dual Motor AWD version that drew strong early demand.

Space finally faced the people living next to its next Terafab mega-project

SpaceX confirmed Terafab’s Grimes County site is locked in, with construction starting within months.

SpaceX and Terafab representatives sat across from Grimes County residents for the first time on Wednesday, telling a packed Commissioners Court room that the $55 billion chip manufacturing project is now a done deal at the Gibbons Creek Reservoir site.

The meeting followed a $10 million check SpaceX sent the county earlier this week, satisfying a payment deadline built into the tax abatement agreement both sides signed in June. Elon Musk shared a post on X confirming the payment, and County Judge Joe Fauth told the San Antonio Express-News his office deposited the check after it beat its deadline.

Wednesday’s session, first reported by KBTX, moved the project from paperwork to construction. Terafab representative Riley Trennell told residents the JETI tax break agreements with Iola ISD and Anderson-Shiro CISD are signed and active, and that civil work and foundation prep are starting almost immediately. Renderings of the facility could be released within days, he said, with construction beginning within months.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry

Musk first announced Terafab in March as a joint venture between Tesla, SpaceX and xAI aimed at producing over a terawatt of AI compute annually, an amount that dwarfs the roughly 20 gigawatts the entire global chip industry produces today. Intel joined as a manufacturing partner in April. Musk has said the project needed its own day in the spotlight rather than being squeezed into an earnings call, and for months the Grimes County site remained unconfirmed even as reporting pointed there.

SpaceX attorney Buck Brannon used Wednesday’s meeting to note that the company’s abatement is roughly 78 percent, not the 100 percent some earlier reports suggested. In exchange, SpaceX will pay Grimes County a fixed $20 million a year for 35 years, a total of $710 million, which Brannon said exceeds the $14 million Tesla paid Travis County in 2025.

SpaceX also addressed environmental concerns that have followed the project since Musk’s Terafab partnership with Intel was announced. Representatives said Terafab will not raise electric bills for other ratepayers, will not deplete local water supplies and will not draw down the Navasota River. SpaceX confirmed it owns the Navasota River pumping station, which it plans to use to divert stormwater into the Gibbons Creek Reservoir, and said it will build its own natural gas plants to power the facility rather than pulling from the ERCOT grid.

Grimes County commissioners also approved an addendum letting county employees use ten approved AI chatbots for work, including Grok.

SpaceX has solved Starship’s biggest challenge, Elon Musk says

Elon Musk has declared that SpaceX has effectively solved one of Starship’s most persistent engineering challenges: the reliability of its heat shield tiles.

During the company’s first-ever Earnings Call, the SpaceX CEO stated:

“I don’t want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn’t mean we won’t make improvements, but we do not see any technical obstacles to achieving rapid reusability at this point.”

Starship’s heat shield consists of roughly 18,000 hexagonal ceramic tiles covering the windward side of the upper stage. These tiles form the thermal protection system that shields the vehicle’s stainless-steel structure from the extreme heat of atmospheric reentry.

During descent, atmospheric friction generates temperatures exceeding several thousand degrees Celsius and creates plasma flows capable of melting unprotected metal. The tiles absorb, radiate, and insulate against this energy, allowing the vehicle to survive and potentially fly again. Without a durable heat shield, full and rapid reusability, the cornerstone of Starship’s design for frequent launches, satellite deployments, and deep-space missions, would remain impossible.

The tiles have long been a source of difficulty. On earlier test flights, a significant number of tiles detached during ascent due to vibration, aerodynamic loads, and imperfect attachment methods using pins and adhesives. Gaps between tiles allowed hot plasma to infiltrate, causing secondary damage and hot spots on the underlying structure.

These issues echoed challenges faced by NASA’s Space Shuttle, whose ceramic tiles required extensive, labor-intensive inspections and replacements between missions, preventing rapid turnaround. SpaceX has iteratively improved materials, standardized tile shapes, refined attachment techniques, added secondary ablative layers, and tested sealing methods such as “crunch wrap” felt to close gaps.

Progress was visible across Flights 10–12, with steadily better tile retention, yet questions remained about whether the system could support the minimal-refurbishment goal of rapid reuse.

Flight 13 on July 24 provided the decisive evidence. Ship 40 flew a deliberately more demanding profile with higher dynamic pressure to stress the heat shield beyond typical operational loads. It successfully deployed 20 operational Starlink V3 satellites, the first such payload on a Starship mission, performed an in-space Raptor engine relight, and executed a controlled reentry.

Cameras on six of the satellites and onboard sensors captured extensive imagery and data of the shield throughout the flight. The ship then achieved its softest splashdown to date in the Indian Ocean, remaining intact and floating rather than breaking apart or exploding as on prior missions. This allowed drone inspections and continuous telemetry of the heat shield in near-real time.

Post-flight analysis showed the majority of tiles remaining attached with only minor damage and limited plasma streaking at seams. Musk noted that the mission delivered “all the heat shield data we needed and then some.” Combined with visual inspections, these results underpinned his subsequent assessment that the core technical barriers to rapid reusability have been cleared. While refinements will continue, Flight 13 marked a pivotal step toward Starship’s operational future.
