NASA currently has an orbiter circling the asteroid Bennu about 200 million miles from Earth, and a live streamed attempt to collect a sample from its surface will be made next week.

The mission, OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer), was developed to help improve our understanding of asteroid impact risks and study how planets and life in the universe began. After a two-year-long journey through deep space, Bennu’s surface has been studied by the orbiter extensively since its arrival in 2018 in preparation for its historic mission. If successful, the craft will land on the asteroid and gather a 2.1 ounce sample that will be returned to our planet in 2023.

“Bennu contains material from the early solar system and may contain the molecular precursors to life and Earth’s oceans,” NASA’s announcement of the live stream detailed. “The asteroid is about as tall as the Empire State Building and could potentially threaten Earth late in the next century, with a 1‐in‐2,700 chance of impacting our planet during one of its close approaches.”

NASA’s live web cast of the event will begin at 6:12 pm EDT on Tuesday, October 20th. Press briefings and other social media activities will be held on October 19th beginning at 1 pm EDT.

OSIRIS-REx, which is about 20 feet long and 10 feet high with its solar panels extended, has a two-part system to collect its asteroid sample. The first, a Touch-And-Go Sample Acquisition Mechanism (TAGSAM), is an articulated robotic arm with a sampler head that extends to the surface to gather regolith. Second, a Sample Return Capsule (SRC), acts as a container with a heat shield and parachutes that will both protect the asteroid regolith and enable reentry into Earth’s atmosphere. The mission is the first of its kind for NASA. Its predecessor is Japan’s Hayabusa mission which returned from with its asteroid sample in 2010.

NASA has been hard at work over the last decade with its deep space missions. Most recently, the agency’s Insight lander has been making progress studying “Marsquakes” after arriving on Mars in 2018. The newest Mars rover, Perseverance, is en route to the red planet where it will collect a sample of its own from the surface to return to Earth in a future mission. That mission also includes the first rotary craft experiment that will attempt flight on another planet.

Another mission similar to OSIRIS-REx is NASA’s DART (Double Asteroid Redirection Test) spacecraft, scheduled to launch aboard a SpaceX Falcon 9 rocket in July 2021. DART will crash into the asteroid Didymos in 2022, and a European Space Agency orbiter will head to the asteroid in 2023 to study the event’s effects on the space object. Collected data will help formulate planetary defense plans by providing detailed analysis from DART’s real-time asteroid deflection experiment.

Tesla Roadster event gets delayed due to unfavorable weather

Tesla is delaying its event for the Roadster, moving it from this Thursday, October 1, to Thursday, October 15, due to unfavorable weather.

The company has said it has been tracking the weather for this Thursday closely with local meteorologists, and because the event can only be held outside, Tesla is making the call to delay it:

“We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule. New date is October 15. Additional details to follow.”

We are sure that this is bringing back PTSD for some Tesla fans, and we know it is not ideal, but this also reveals some things about the event. Tesla said that this can only be held outdoors, meaning it bodes well for the rumors that the vehicle could potentially hover.

Some believe that this was essentially confirmed by the FAA airspace restriction they were granted, but this could have been for a drone show or to keep drones from spying on the event.

Tesla Roadster is available for order once again following brief hold

The Roadster event has been long-awaited, and it is unfortunate that the weather is going to keep us all waiting a little bit longer.

The Tesla Roadster will be unveiled in Waco, Texas.

Elon Musk

SpaceX turned a heralding moment for Starship into its greatest

Starship reached orbit despite losing an engine, deployed 26 Starlink V3 satellites on Flight 14.

SpaceX’s Starship reached orbit for the first time on Monday, and for a few nail-biting minutes it looked like it wouldn’t. During ascent on Flight 14, one of Ship 41’s six Raptor engines shut down early, and SpaceX’s livestream host Dan Huot told viewers the team had decided not to commit to orbit. Minutes later, after what Huot described as a lot of conversation in the control room, the final poll came back in favor, and a roughly 19 second burn of a single Raptor pushed the ship into orbit about 170 miles up.

The reversal matters because SpaceX had written the exit ramp into the mission plan. The company said it would only fire the orbital insertion burn if flight controllers confirmed enough backup hardware remained for the deorbit burn, a condition Teslarati laid out ahead of the flight. Losing an engine was exactly the scenario that rule was built for.

Pressing forward fits Elon Musk’s history. Falcon 1 failed three straight times before its fourth launch reached orbit in 2008, with SpaceX nearly out of money, and Starship was developed by flying prototypes until they broke. What changed this year SpaceX going public, and with $SPCX sliding below its IPO price in July when Flight 13 slipped, the short interest climbed significantly, as Teslarati reported at the time. A Starship potentially lost today with revenue generating next-gen Starlink satellites aboard would have landed directly on shareholders.

That pressure showed up after orbit. SpaceX cut a flight planned to last nearly 10 hours to about three, moving splashdown from west of Chile to the North Pacific near Hawaii. SpaceX gave no reason, though Musk said this month the company was being extremely cautious about debris risk. The single Raptor for deorbit worked, and Ship 41 completed its flip and landing burn before breaking apart in the water, an outcome SpaceX expected. Musk has structured SpaceX’s governance to shield long term bets from market pressure.

The payload is the bigger business story. Musk posted that all 26 Starlink V3 satellites deployed and are “operating nominally.” Each V3 is rated for about 1 Tbps of downlink and 160 Gbps of uplink, so this single launch adds roughly 26 Tbps, about 10 times what a Falcon 9 load of V2 Mini satellites adds. The V3 is too large for Falcon 9, making Starship the only vehicle that can build out the planned 100,000 satellite constellation, at up to 60 per flight once it reaches routine service. Unlike the 20 V3 units on Flight 13, which reentered on a suborbital path, these will raise their orbits and could begin serving customers within weeks and bring in hundreds of millions of additional dollars in projected Starlink revenue.

SpaceX has already begun winding down Falcon 9 Starlink launches from Florida in favor of Starship. Reported targets put Flight 15 as early as October 19, leaving about three weeks to diagnose Monday’s engine shutdown before the next orbital attempt.

Tesla Cybercab fleet doubles to well over 100 units

Tesla quietly doubled the size of its Cybercab fleet within the Robotaxi program in Austin, Texas, over the weekend to well over 100 units.

The move not only establishes more of the steering-wheel-less and pedal-less vehicles within the ride-sharing fleet Tesla has been operating for a year, but it also solidifies a more robust Robotaxi fleet as a whole.

Riders started receiving notifications from the Robotaxi app that stated: “Cybercab fleet has doubled: more rides available.”

Tesla first launched rides in the Cybercab in early September, although the Robotaxi fleet has been active for over a year, as rides began last Summer. Cybercab is truly Tesla’s most crucial vehicle release yet, as it is the first car any company has built that is geared toward full-fledged and end-to-end autonomy, never needing human intervention for anything.

Only available in Austin at the current time, Cybercab has two seats and has been spotted testing around various U.S. states and regions; Tesla plans to deploy the Cybercab in various U.S. cities in the coming months as a best-case scenario.

Tesla Cybercab gets initial tie-in to localized, in-house cathode plant

The availability of the Cybercab has doubled from just 58 units last Monday to 125 the following Friday. Marking a substantial increase in Cybercab availability, the additional ride-sharing units are more than welcome, as wait times for Cybercabs, especially, were quite high.

The dramatic increase is a sign that demand for Robotaxi is growing and Tesla is feeling more confident that its driverless ride-hailing suite, especially its Full Self-Driving software, is able to handle any traffic situation without explicit direction or supervision from a human being.
