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 lands new partnership with Uber as Semi takes center stage

Tesla and Uber will work together, using the company’s all-electric Semi, to make sustainable Class 8 electric trucks more affordable with three main strategies: Subsidized Pricing, Predictable Growth, and Optimization of Utilization.

The Tesla Semi has led to a new partnership between the company and Uber, as the two are launching a program that aims to revolutionize logistics by making sustainable commercial vehicles more accessible.

Uber announced on Tuesday that it was planning to launch the Dedicated EV Fleet Accelerator Program in a new partnership with Tesla. Uber’s Freight division is mainly responsible for the new program, which it calls a “first-of-its-kind buyer’s program designed to make electric freight more affordable and accessible by addressing key adoption barriers.”

Tesla and Uber will work together, using the company’s all-electric Semi, to make sustainable Class 8 electric trucks more affordable with three main strategies: Subsidized Pricing, Predictable Growth, and Optimization of Utilization.

  • Subsidized Price: Fleets purchasing Tesla Semis through this program will receive a subsidy on the purchase price.   
  • Predictable Growth: Fleets will integrate their Tesla Semis into Uber Freight’s dedicated solutions for shippers for a pre-determined period. This creates an opportunity for carriers to forecast revenue with confidence, while shippers gain consistent access to reliable, zero-emission capacity. 
  • Optimize Utilization: Uber Freight taps into its extensive freight network to match carriers with consistent, high-quality freight from our strong shipper base—helping ensure the addition of these Tesla Semis stay fully utilized and carriers see dedicated, real, measurable returns from the start

Tesla will work directly with interested companies to iron out technical details about the Semi, as well as its cost of ownership based on the tailored needs of their business. Fleets can expect savings on the first day, Uber says, as they will avoid diesel fuel costs and reduced maintenance, a widely known advantage of EVs.

Uber announced that it had partnered with select carriers to pilot the Dedicated EV Fleet Accelerator Program prior to its launch:

“During the 2-month pilot program, the Tesla Semis showcased both reliability and efficiency for Uber Freight’s shipper network. Over 394 hours of drive time, carriers covered 12,377 miles. With an average net energy consumption of just 1.72 kWh per mile and only 60 hours of total charge time, these results highlight the operational viability of Tesla Semis on demanding freight lanes. “

In its press release launching the program, Uber effectively highlights how the use of the Semi can impact a company’s margins and profitability through fuel savings, reduced maintenance costs, and lower total cost of ownership.

This is something that turns so many people away from gas cars and toward EVs, so it’s no surprise that Uber wanted to emphasize this point on a larger scale with a company that utilizes a fleet of vehicles.

Tesla has been experimenting with a select group of companies, as well. It partnered with PepsiCo. several years ago, in an effort to launch a pilot program for the Semi. It had excellent results, showing higher efficiency, lower costs, and an exceptional ability to handle long runs.

Drivers have had a lot of positive things to say:

Tesla will recall Powerwall 2 units in Australia after a handful of property owners reported fires that caused “minor property damage.” The fires were attributed to cells used by Tesla in the Powerwall 2.

Tesla Powerwall is a battery storage unit that retains energy from solar panels and is used by homeowners and businesses to maintain power in the event of an outage. It also helps alleviate the need to rely on the grid, which can help stabilize power locally.

Powerwall owners can also enroll in the Virtual Power Plant (VPP) program, which allows them to sell energy back to the grid, helping to reduce energy bills. Tesla revealed last year that over 100,000 Powerwalls were participating in the program.

The Australia Competition and Consumer Commission said in a filing that it received several reports from owners of fires that led to minor damage. The Australian government agency did not disclose the number of units impacted by the recall.

The issue is related to the cells, which Tesla sources from a third-party company.

Anyone whose Powerwall 2 unit is impacted by the recall will be notified through the Tesla app, the company said.

Tesla is launching Cybertruck orders in a new market, but there’s a bit of a catch.

The Cybertruck was launched in the Middle East earlier this year, as Tesla launched the ability to place a reservation for the all-electric pickup in the United Arab Emirates. It would be the first market outside of North America that would have the ability to place an order for the Cybertruck.

Tesla confirms Cybertruck will make its way out of North America this year

Other markets where the vehicle has been widely requested, like Europe and Asia, have still not approved the vehicle to be sold to the public, mostly because of size and design restrictions.

However, in the UAE, Tesla is opening up the ability for those who placed reservations for the vehicle to finally put in their order. The Order Configurator is only available to those who have already placed a reservation; it is not yet available to the public.

Tesla said it would open up the public online configurator across the Middle East in the coming weeks:

The UAE is not the only country that will have access to the Cybertruck, as fans in other Middle Eastern countries will also be able to place orders soon. Tesla announced back in April that Saudi Arabia and Qatar would also have Cybertruck deliveries.

These vehicles will be built at Tesla’s Gigafactory Texas plant just outside of Austin, as Gigafactory Berlin and Gigafactory Shanghai, two factories located in the same hemisphere as the Middle East, do not have established lines for Cybertruck production.

As for the other markets, Tesla CEO Elon Musk has hinted that the company could develop a smaller Cybertruck for those markets, as he admitted that in the long term, it likely made sense to build a more compact version for regions where roads are traditionally tighter.

There has been no evidence of Tesla developing this more compact version, but it could eventually happen.
