Antares rocket launches Cygnus spacecraft to the International Space Station
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.

Waymo scrutinized after self-driving taxis cause traffic jams during SF blackout
It’s not farfetched to speculate that it would have been a doomsday scenario for Tesla had FSD behaved this way.
A power outage across San Francisco over the weekend forced numerous Waymo self-driving taxis to stop at darkened intersections and cause traffic blockages in multiple locations across the city. The disruption left riders stranded, frustrated drivers blocked, and city officials stepping in as the Alphabet-owned company temporarily suspended service amid the widespread gridlock.
Needless to say, it would likely have been a doomsday scenario for Tesla had FSD behaved in a similar way, especially if fleets of its robotaxis blocked traffic for numerous drivers.
Power outage halts Waymo fleet
The outage knocked out electricity for tens of thousands of customers, leaving traffic signals dark across large parts of the city, as noted in a report from the New York Times. Waymo vehicles began stopping at intersections and remained stationary for extended periods, seemingly unable to operate. Tow truck operators worked through the night removing immobilized vehicles, while videos circulated online showing Waymos with hazard lights flashing as traffic backed up around them.
Waymo later confirmed that it had paused its Bay Area ride-hailing service after the San Francisco mayor’s office contacted the company about the congestion its vehicles were contributing to. Service began coming back online shortly after 3:30 p.m. local time, though some users still reported being unable to request rides. Waymo maintained that no injuries or accidents were reported during the outage.
Autonomous cars during emergencies
The incident surprised industry observers since autonomous vehicles are designed to function during signal outages and temporary connectivity losses. Waymo stated that its vehicles treat nonfunctional signals as four-way stops, but “the sheer scale of the outage led to instances where vehicles remained stationary longer than usual to confirm the state of the affected intersections. This contributed to traffic friction during the height of the congestion.” Experts suggested the problem may have been linked to the vehicles’ reliance on remote assistance teams, which help resolve complex situations the cars cannot handle independently.
“Yesterday’s power outage was a widespread event that caused gridlock across San Francisco, with non-functioning traffic signals and transit disruptions. While the failure of the utility infrastructure was significant, we are committed to ensuring our technology adjusts to traffic flow during such events,” the Waymo spokesperson stated, adding that it is “focused on rapidly integrating the lessons learned from this event, and are committed to earning and maintaining the trust of the communities we serve every day.”

Tesla aims to combat common Full Self-Driving problem with new patent
Tesla writes in the patent that its autonomous and semi-autonomous vehicles are heavily reliant on camera systems to navigate and interact with their environment.
Tesla is aiming to combat a common Full Self-Driving problem with a new patent.
One issue with Tesla’s vision-based approach is that sunlight glare can become a troublesome element of everyday travel. Full Self-Driving is certainly an amazing technology, but there are still things Tesla is aiming to figure out with its development.
Unfortunately, it is extremely difficult to get around this issue, and even humans need ways to combat it when they’re driving, as we commonly use sunglasses or sun visors to give us better visibility.
Cameras obviously do not have these ways to fight sunglare, but a new patent Tesla recently had published aims to fight this through a “glare shield.”
Tesla writes in the patent that its autonomous and semi-autonomous vehicles are heavily reliant on camera systems to navigate and interact with their environment.
The ability to see surroundings is crucial for accurate performance, and glare is one element of interference that has yet to be confronted.
Tesla described the patent, which will utilize “a textured surface composed of an array of micro-cones, or cone-shaped formations, which serve to scatter incident light in various directions, thereby reducing glare and improving camera vision.”
The patent was first spotted by Not a Tesla App.
The design of the micro-cones is the first element of the puzzle to fight the excess glare. The patent says they are “optimized in size, angle, and orientation to minimize Total Hemispherical Reflectance (THR) and reflection penalty, enhancing the camera’s ability to accurately interpret visual data.”
Additionally, there is an electromechanical system for dynamic orientation adjustment, which will allow the micro-cones to move based on the angle of external light sources.
This is not the only thing Tesla is mulling to resolve issues with sunlight glare, as it has also worked on two other ways to combat the problem. One thing the company has discussed is a direct photon count.
CEO Elon Musk said during the Q2 Earnings Call:
“We use an approach which is direct photon count. When you see a processed image, so the image that goes from the sort of photon counter — the silicon photon counter — that then goes through a digital signal processor or image signal processor, that’s normally what happens. And then the image that you see looks all washed out, because if you point the camera at the sun, the post-processing of the photon counting washes things out.”
Future Hardware iterations, like Hardware 5 and Hardware 6, could also integrate better solutions for the sunglare issue, such as neutral density filters or heated lenses, aiming to solve glare more effectively.

Delaware Supreme Court reinstates Elon Musk’s 2018 Tesla CEO pay package
The unanimous decision criticized the prior total rescission as “improper and inequitable,” arguing that it left Musk uncompensated for six years of transformative leadership at Tesla.
The Delaware Supreme Court has overturned a lower court ruling, reinstating Elon Musk’s 2018 compensation package originally valued at $56 billion but now worth approximately $139 billion due to Tesla’s soaring stock price.
The unanimous decision criticized the prior total rescission as “improper and inequitable,” arguing that it left Musk uncompensated for six years of transformative leadership at Tesla. Musk quickly celebrated the outcome on X, stating that he felt “vindicated.” He also shared his gratitude to TSLA shareholders.
Delaware Supreme Court makes a decision
In a 49-page ruling Friday, the Delaware Supreme Court reversed Chancellor Kathaleen McCormick’s 2024 decision that voided the 2018 package over alleged board conflicts and inadequate shareholder disclosures. The high court acknowledged varying views on liability but agreed rescission was excessive, stating it “leaves Musk uncompensated for his time and efforts over a period of six years.”
The 2018 plan granted Musk options on about 304 million shares upon hitting aggressive milestones, all of which were achieved ahead of time. Shareholders overwhelmingly approved it initially in 2018 and ratified it once again in 2024 after the Delaware lower court struck it down. The case against Musk’s 2018 pay package was filed by plaintiff Richard Tornetta, who held just nine shares when the compensation plan was approved.
A hard-fought victory
As noted in a Reuters report, Tesla’s win avoids a potential $26 billion earnings hit from replacing the award at current prices. Tesla, now Texas-incorporated, had hedged with interim plans, including a November 2025 shareholder-approved package potentially worth $878 billion tied to Robotaxi and Optimus goals and other extremely aggressive operational milestones.
The saga surrounding Elon Musk’s 2018 pay package ultimately damaged Delaware’s corporate appeal, prompting a number of high-profile firms, such as Dropbox, Roblox, Trade Desk, and Coinbase, to follow Tesla’s exodus out of the state. What added more fuel to the issue was the fact that Tornetta’s legal team, following the lower court’s 2024 decision, demanded a fee request of more than $5.1 billion worth of TSLA stock, which was equal to an hourly rate of over $200,000.
