Just three weeks ahead of liftoff, NASA and launch provider United Launch Alliance (ULA) announced that NASA’s Mars 2020 rover, Perseverance, and its Martian helicopter sidekick, Ingenuity, were mated with the Atlas V 541 rocket that will kick off the seven-month journey to the Red Planet. The precious cargo encapsulated inside of a protective payload fairing was carefully hoisted by crane operators to rest atop the Atlas V rocket. The payload joins the Atlas V common core booster, four solid rocket boosters, and the Centaur upper stage to achieve the stack’s final flight configuration height of 197 feet (60 meters).

The final stacking procedure was completed inside of the Vertical Integration Facility (VIF) at Cape Canaveral Air Force Station’s Space Launch Complex 41 (SLC-41). The rocket and payload will remain inside the protective structure and complete final check out tests until it is time quite literally roll to the launchpad. Crane operators first set down the payload for a soft touch to begin final full physical and electrical connection. The spacecraft and rocket will undergo integrated electrical testing as well as a battery of other tests as separate spacecraft and simultaneously as one complete unit.

On Friday (July 10), ULA president and chief executive officer, Tory Bruno, stated on Twitter that the Integrated Systems Test (IST) had been completed successfully. According to a previous mission statement posted to the ULA blog site, the IST is a typical pre-launch run down of the various connected systems between the spacecraft and launch vehicle to “verify proper functionality of launch vehicle systems, (and) conduct a simulated countdown and run through the launch sequence.”

The launch vehicle and integrated payload will remain inside the VIF undergoing mission-specific activities and final system checkouts over the next two weeks. Once all pre-flight activities have been successfully completed, approximately two days ahead of the scheduled launch attempt, the entire stack located on top of the Mobile Launch Platform will make the 1,800ft (550 meters) trip to the SLC-41 launchpad which will take about forty-minutes on a modified railway.

Known as an astrobiology mission and outfitted with seven instruments, the Perseverance rover will conduct new science, sample collection, and test new technology in search of ancient microbial life on the distant planet. The rover will spend the length of one Martian year – two Earth years – exploring the region around its landing site. It will collect and cache samples of the Martian surface to possibly be collected and returned to Earth by future joint missions currently under consideration by NASA and the European Space Agency.

The first interplanetary helicopter, Ingenuity, is a small 4-pound (1.8 kilograms) autonomous solar-powered aircraft that will conduct a series of experimental test flights. Ingenuity is traveling to Mars solely for a demonstrative mission and is not connected to the Perseverance rover by any means other than hitching a ride to the Red Planet. The new technology will demonstrate an ability to create lift in the thin atmosphere and lower gravity environment of Mars to help inform future aerial exploration and science delivery missions.

Currently, NASA and ULA are targeting the launch of the interplanetary mission on July 30th at 7:50 am EDT/4:50 PDT. Should they be necessary, multiple backup launch opportunities are available until the close of the interplanetary launch window on August 15th. Regardless of the launch date, after a seven-month-long, 290 million mile (467 million kilometers) journey – the rover and helicopter will arrive at Mars’s Jezero Crater, the home to an ancient Martian river delta, for a landing attempt on February 18, 2021. The landing date is perhaps even more crucial than the launch date as mission planners must take into account landing site lighting and temperature conditions and the locations of Mars-orbiting satellites required to relay crucial mission-specific information back to Earth.

Should the launch have to abort, and the 2020 window is missed completely, the robots will have to wait until 2022 when Earth’s orbit lines up just right with that of Mars, and the next interplanetary launch window opens up.

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.

Starlink D2D direct to device vs Verizon, AT&T (Concept render by Grok)

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

Published

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.
