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.

Elon Musk says SpaceX would not exist if this crucial early launch failed

Published

Elon Musk recently restated a fact that still defines SpaceX’s origin story: if Falcon 1’s fourth launch had failed, the company would not exist. The comment answered a reminder that after three consecutive losses, SpaceX had money for only one more attempt.

On X, Peter Diamandis said that the present-day acknowledgement of SpaceX’s success does not discount the rough start the company had. “Almost nobody remembers that Elon’s first rocket failed three times, and there was money for exactly only one more attempt.”

Musk said, “If the 4th launch had failed, SpaceX would not exist.”

In late 2008, the firm was nearly out of cash. Another failure would have ended payroll, closed the Hawthorne factory, and left the Falcon 9 and Dragon programs as unfinished drawings.

The first flight lifted off from Omelek Island on 24 March 2006. Thirty-three seconds later, a corroded aluminum fitting on a fuel line leaked. Kerosene ignited around the Merlin engine, control was lost, and the vehicle came apart. The small DARPA payload, FalconSAT-2, survived the short flight only to land on a storage shed near the pad. Investigators later traced the fitting to a materials mix-up that should never have reached the rocket.

Flight 2, on 21 March 2007, looked far better at first. The first stage burned cleanly and handed off to the Kestrel-powered upper stage. The vehicle crossed 100 kilometers and reached a peak of about 289 kilometers. Then propellant slosh in the second-stage tank started a circular coning motion that grew until the engine shut down. Telemetry faded as the stage tumbled, and SpaceX had reached space but not orbit. Over the next year, the team redesigned everything from the ground up, including tanks, baffles, and the new regeneratively cooled Merlin 1C.

That engine flew on Flight 3 on 2 August 2008. The first stage performed almost perfectly and reached 217 kilometers. After main-engine cutoff, leftover fuel in the cooling channels produced a faint residual thrust, roughly 10 pounds per square inch of chamber pressure. On a Texas test stand, the effect was invisible beneath ambient air pressure. In vacuum it was enough to push the spent first stage back into the second stage after separation. The stages collided, the upper stage spun, and the mission was lost. Musk later said a slightly longer delay before staging would have saved the flight.

Six weeks later, the team assembled Flight 4 from remaining parts and flew it on 28 September 2008 at 23:15 UTC. The payload was Ratsat, a 165-kilogram aluminum mass simulator built in-house. Staging was delayed so residual thrust could decay. The Kestrel ignited, the fairing split away, and nine and a half minutes after liftoff the vehicle was in orbit. After a coast, the second stage restarted, settling into a 621-by-643-kilometer path at 9.35 degrees inclination. Falcon 1 became the first privately developed liquid-fueled rocket to reach Earth orbit. Musk called the insertion “middle of the bull’s-eye.”

SpaceX restores a Falcon 1 rocket for 10th anniversary of first launch success

That success unlocked NASA’s Commercial Resupply Services award later that year. Without it, there would have been no Falcon 9, no reusable first stages, and no Dragon cargo or crew flights to the International Space Station. Launch prices would have remained far higher. Starlink’s constellation would not exist; broadband from low Earth orbit would still be a paper concept.

Ride-share markets, high launch cadence, and the current pace of lunar and Mars hardware would be years behind. Communications, Earth observation, and the cost of putting anything into space would look more like the 2000s than the 2020s.

One extra second of residual thrust in August 2008 would have written a different decade.

Tesla surges Robotaxi fleet ahead of Cybercab launch event

Tesla’s unsupervised robotaxi fleet quietly grew sevenfold in three weeks just before Cybercab Day arrives.

Published

By

Tesla’s unsupervised Robotaxi fleet has grown far faster than the public numbers suggested, and the timing lines up with the company’s biggest autonomy showcase yet. According to data compiled by the crowdsourced Robotaxi Tracker, Tesla now has nearly 200 vehicles operating without a safety monitor across Austin, Dallas and Houston, yielding a roughly 7X increase in about three weeks.

The jump lands four days before this week’s Tesla Cybercab launch event in Austin, where the company plans to show off its purpose-built, two-seat robotaxi with no steering wheel or pedals in a live commercial setting for the first time. Stick with us on X and Facebook for live reporting from the event.

The strategic logic is straightforward. Tesla has spent the past year scaling Robotaxi in small, deliberate steps, first widening geofences, then extending operating hours, then quietly growing fleet size, usually with little advance notice. Ashok Elluswamy told investors on the Q2 earnings call that the program had logged more than 380,000 unsupervised miles with zero notable incidents, a safety record the company has leaned on to justify moving slowly. Critics have used the flip side of that caution, a fleet that appeared stuck around two dozen vehicles for months, as evidence that Tesla’s driverless ambitions were outrunning its actual deployment.

A fleet quietly scaling to nearly 200 vehicles right before Cybercab Day undercuts that argument without Tesla having to say anything about it directly. It also sets up the event to do double duty. Rather than simply introducing new hardware, Tesla can point to an operating base of unsupervised Model Ys already running at meaningful scale, then argue the Cybercab, which uses the same underlying Full Self-Driving stack according to earlier coverage of the fleet’s software upgrades, is a natural next steps. Tesla has separately been registering the two-seat Cybercabs with Texas regulators this week, with the count climbing from seven to 45 in a matter of days.

The two ramps, one in software-driven Model Y deployment and one in physical Cybercab registrations, are happening in parallel rather than in sequence. That suggests Tesla wants Thursday’s event to land as proof that the robotaxi business is already running at scale, not just a reveal of a new vehicle shape. Whether the unsupervised numbers hold up once Cybercabs start mixing into the same fleet is the detail worth watching once the event wraps.

Tesla Cybertruck windshield protection just got cheaper

Published

Tesla is lowering the monthly price of its Cybertruck Windshield Protection Plan from $35 to $25. The new rate will apply to the first payment on or after October 1, 2026. Tesla has told subscribers that all other benefits stay the same.

The plan covers unlimited repairs for chips and minor cracks on the front windshield. It also includes one full replacement every 12 months at no extra charge. Additional replacements in the same year carry a $100 deductible. Service is performed with Tesla glass and camera calibration, which matters because Autopilot and Full Self-Driving rely on those lenses behind the windshield.

There is no long-term contract. Coverage applies only to the front glass and does not include collision, vandalism, or weather damage.

The Cybertruck’s large, complex windshield has been more expensive to replace than glass on Tesla’s cars, which is why the pickup started at a higher subscription price. The $10 monthly cut reduces the annual cost from $420 to $300. Tesla has not publicly explained the change. The timing coincides with a year of claims data after the plan was extended to the Cybertruck.

Tesla sells several related protection products as monthly subscriptions through the Tesla app. The Windshield Protection Plan is also offered on other models. Model 3 and Model Y currently cost $16 a month. Those passenger-car rates are unchanged in the latest Cybertruck notice.

The Wheel and Tire Protection Plan covers road-hazard damage such as potholes, nails, and debris. Repairs are unlimited. Each wheel or tire replacement appointment has a $25 deductible. Pricing varies by model and whether the vehicle is a Performance version. Tesla is raising some of those rates on the same October 1 date.

Reported examples include Model 3 Performance moving from $16 to $24 and Model Y Performance from $20 to $24. Cybertruck wheel-and-tire coverage has been listed at $20 a month for the standard configuration.

A separate Luxe Package bundles four years of windshield coverage, wheel-and-tire coverage, and recommended maintenance on certain new Model S, Model X, and Cyberbeast orders, although the Model S and X are now defunct.

Tesla also offers an Extended Service Agreement after the basic vehicle warranty ends. That product covers many Tesla-manufactured parts rather than glass or tires. Together, the plans give owners a menu of targeted, cancel-anytime coverage instead of relying only on auto insurance.
