Both SpaceX and Boeing are pushing hard to complete capsules that will carry astronauts into space. At Kennedy Space Center, Boeing has just completed joining together the two halves of its CST-100 Starliner crew capsule. It is precursor to the units that will carry humans into orbit. The so-called “structural test article” will be shipped to Huntington Beach, California, this summer for tests.

Meanwhile, the main pieces of what Boeing calls “Spacecraft 1” have just arrived in Florida. “We’re bringing hardware in. We’re moving hardware out. And it’s really nice to see the factory flowing the way it should be,” said Danom Buck, manufacturing engineering manager for Boeing.

Prompted by a cooling in diplomatic relations between the US and Russia over activities in the Ukraine, NASA awarded contracts to both Boeing and SpaceX to fly astronauts to the International Space Station in 2014. The Boeing contract is worth up to $4.2 billion. The SpaceX contract is worth $2.6 billion. Both capsules are supposed to be ready to fly by late 2017.

SpaceX says it is on schedule with launching its Dragon space capsule later this year while Boeing aims to February, 2018 for the first launch of the Spacecraft 1. SpaceX will use a Falcon Heavy rocket for its manned space mission. Boeing’s capsule will be lifted into space atop a United Launch Alliance Atlas V rocket. ULA is a partnership between Boeing and Lockheed.

On May 24, representatives of both companies announced they are making good progress toward the proposed target date for launching their space capsule. “Astronauts will once again fly from the Space Coast,” said Lisa Colloredo, associate manager of NASA’s Commercial Crew Program.”

The NASA contracts are designed to eliminate reliance on Russia for transporting astronauts to and from the ISS. It is expected the American ventures will ultimately save NASA money compared to what it costs to fly them into space and back again aboard the Soyuz spacecraft that are being used now.

NASA’s Colloredo said the contracts will result in per seat prices averaging $58 million, which is about $23 million less than Russia’s going rate for Soyuz seats. “The cost effectiveness part, we weren’t 100 percent sure how that would turn out,” she said. “It turns out it is a very cost effective approach to go with the private industry.” All together, Colloredo said, the program will produce two certified crew systems for less than $5 billion, a relative bargain compared to historical costs to develop such systems.

In January, SpaceX completed a critical test of the SuperDraco rocket engines that are mounted to the outside of the Dragon space capsule. Instead of using traditional parachutes to return the capsule to earth, it plans to use those engines to gently slow the capsule for a soft landing. That is the sort of innovative thinking that continues to set SpaceX apart from its foreign and domestic competitors.

Verizon, AT&T and T-Mobile are trying to shut Starlink out before FCC vote

AT&T, Verizon and T-Mobile want 290 MHz cut from an FCC satellite plan before Thursday.

AT&T, Verizon and T-Mobile are asking the Federal Communications Commission to pull nearly 300 MHz of spectrum out of a proposal that would let satellite companies like SpaceX offer cell service directly to ordinary phones. The request lands one day before the agency votes on it.

The FCC will vote Thursday, October 29, on a notice of proposed rulemaking that would make an additional 482 MHz available for direct to device service, expanding the number of eligible bands from five to 13, according to the FCC fact sheet. It would also scrap the rule requiring a satellite operator to lease spectrum from carriers, replacing it with a certification that the operator has coexistence agreements in place or holds the terrestrial license itself.

That second path matters for SpaceX. As Teslarati reported earlier this month, SpaceX agreed to buy Grain Management’s nationwide 800 MHz portfolio to turn Starlink Mobile into a full US carrier, adding to the spectrum it already bought from EchoStar.

The carriers want two bands removed, 2.5 GHz and 3.45 GHz, which make up 290 MHz of the 482 MHz on the table. Through industry group CTIA, they argued that about 300 million users depend on those bands and that satellite operations in them are not technically feasible. T-Mobile, which calls 2.5 GHz the foundation of its Ultra Capacity 5G network, said in its own filing that satellite interference could wipe out up to 96% of a cell site’s uplink coverage area and cut uplink speeds by 88% to 99%.

Executives from all three carriers met with FCC staff on October 20, and T-Mobile CEO Srini Gopalan met separately with FCC Chairman Brendan Carr. T-Mobile’s role stands out because it is still SpaceX’s US launch partner for Starlink Mobile. The three carriers have also teamed up on their own satellite joint venture to pool spectrum, a move widely seen as a response to Starlink.

SpaceX is asking for the opposite. In an October 23 filing after meetings with FCC staff and commissioners’ offices, the company asked regulators to add the 902 to 928 MHz band to the proposal. “Doing so now saves time later,” SpaceX wrote. The company also asked the FCC to modernize interference rules and align satellite deployment requirements with those for terrestrial cell networks, saying the goal is to let satellite and ground networks work together so Americans stay connected wherever they are.

The carriers have not been shy about how they view SpaceX as a competitor. On Verizon’s third quarter earnings call Monday, its chief executive said Starlink Mobile “just can’t compete with a terrestrial network” and estimated SpaceX would need four to six years and $300 billion to $500 billion to build a full US carrier network.

Thursday’s vote will not settle which bands survive. Adopting the notice opens a public comment period, with final rules to come later in the proceeding. The FCC already considered and rejected 2.5 GHz for satellite coverage once, in 2024. SpaceX also is not the only satellite player watching: the FCC approved Amazon’s $11.6 billion acquisition of Globalstar on October 27, giving its planned direct to device fleet its own mobile satellite spectrum.

Tesla Semi catches fire in California: what we know

Published

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.

The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.

There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.

However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.

The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.

The truck’s driver said that the Semi caught fire, but he did not have an explanation.

An estimated 5,000 to 7,000 semi-truck and large commercial vehicle fires occur on U.S. roadways every year.

Tesla’s ‘Emergency Drive Away’ function gets its first use in the real world

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.

A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.

“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.

Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.

Tesla constitutes the following situations as reasonable justifications for activating the feature:

  • You face an immediate threat to your life or personal safety.
  • You must leave the area immediately.
  • Exiting the vehicle is unsafe.
  • Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.

After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.
