NASA SLS rocket launches Orion spacecraft to the Moon

Published

on

After years, months, days, hours, and minutes of waiting, NASA’s first Space Launch System (SLS) rocket has successfully lifted off from Kennedy Space Center and sent an Orion spacecraft on its way to the Moon.

Originally projected to launch by late 2016, SLS lifted off for the first time at 1:48 am EST (06:48 UTC) on November 16th, 2022. Once known as Exploration Mission 1 (EM-1), NASA’s SLS debut was renamed “Artemis I” when the Trump administration created the Artemis Program in 2017. By most measures a semi-modernized Apollo Program without a geopolitical race against the Soviet Union, the Artemis Program survived the election of a new president in 2020, and the SLS rocket’s debut has officially become the program’s first major mission to get off the ground.

That SLS rocket has had a very long journey to its first successful launch. Supplied by United Launch Alliance (ULA), the rocket’s small Interim Cryogenic Propulsion Stage (ICPS) – the stage responsible for orbital burns – was delivered to the Kennedy Space Center in November 2017. Boeing shipped the first Core Stage – SLS’ central liquid rocket booster – to Mississippi for proof testing in January 2020, and CS-1 completed that testing in March 2021 and was delivered to Florida by April 2021.

After almost 12 months of painstaking assembly, the first fully-assembled SLS rocket rolled out to Kennedy Space Center Launch Complex 39B (Pad 39B) and attempted its first on-pad wet dress rehearsal (WDR) test. Seven months, three partially-completed WDRs, and two aborted launch attempts later, everything finally came together on November 16th, 2022.

By all appearances, the first SLS launch went perfectly. Shortly before liftoff, SLS ignited four former Space Shuttle Main Engines, making sure they were performing as expected. Seconds later, the launch computer fully committed and ignited both of SLS’ Shuttle-derived solid rocket boosters (SRBs) – motors than cannot be shut down after they’re lit. Much like the Shuttle did, SLS leapt off the pad after SRB ignition.

Combined, NASA says its RS-25 liquid engines and SRBs produced up to 4000 tons (8.8M lbf/39,200 kN) of thrust at liftoff, making SLS the second most powerful rocket to ever leave the launch pad. Only the Soviet Union’s N1 rocket, which produced up to 4500 tons (9.9M lbf/44,100 kN) of thrust at liftoff, was more powerful. But unlike N1, which failed four times over four launch attempts, the first SLS rocket reached orbit as planned, making it the most powerful rocket ever successfully launched.

About two minutes after liftoff, both SRBs successfully separated from the Core Stage. Eight and a half minutes after liftoff, the Core Stage shut down its four RS-25 engines and deployed the ICPS and Orion spacecraft just below the height of a stable orbit. 51 minutes after liftoff, ICPS ignited its lone RL-10 engine for 22 seconds to insert itself and Orion into a stable Earth orbit. Finally, about an hour and forty minutes after liftoff, ICPS ignited for a lengthy 18-minute trans-lunar injection (TLI) burn, sending Orion on a trajectory that will intercept the Moon on November 21st.

If all goes according to plan, Orion will then use its own European Service Module (ESM) to correct its trajectory and enter a Distant Retrograde Orbit around the Moon on November 25th, where it will remain tens of thousands of kilometers above the lunar surface. Orion will then leave lunar orbit as early as December 1st and reenter Earth’s atmosphere on December 11th before the capsule finally splashes down in the ocean.

Assuming Artemis I goes perfectly, Artemis II – SLS and Orion’s first launch with astronauts aboard – is scheduled no earlier than (NET) 2024. Artemis III, which will team up with a modified version of SpaceX’s Starship launch vehicle to attempt to land astronauts on the Moon for the first time since 1972, is expected to follow NET 2025. However, a reliable source with a prophetic track record estimates that Starship and SLS might not be ready to launch Artemis III until 2028.

Tesla finally got its Nevada Robotaxi Permit but with a few catches hard to miss

Nevada granted Tesla’s robotaxi permit, but capped the fleet at just ten vehicles for now.

Tesla has received its robotaxi permit in Nevada, more than two months after regulators closed the public comment period on the company’s application. News of the approval surfaced Wednesday night when Tesla investor and longtime company watcher Sawyer Merritt posted a copy of the interim order, and the Nevada Transportation Authority’s own carrier registry now lists the permit, AVNC Permit 002 under Docket 26-05015, as active for Tesla Robotaxi, LLC.

Tesla asked Nevada in June for authority to run up to 5,000 vehicles in Clark County within a year, however the permit the NTA issued is initially capping Tesla at ten fully autonomous vehicles and confines them to a defined geofence along the Las Vegas Strip corridor. Any expansion of that operating area, or any increase to the fleet size, requires the NTA’s approval first.

The order also sets rules that look more restrictive than what Tesla runs in Austin. Rides are barred on roads with posted speed limits above 45 miles per hour, pickups are off limits within a quarter mile of Harry Reid International Airport without separate authorization, and every vehicle has to carry visible “Robotaxi” markings while notifying riders before each trip that no one is driving. The order also requires “appropriate human supervision”, language that suggests Nevada isn’t ready to let Tesla offer the rides without a safety monitor that it has run in parts of Austin since January. As with standard protocol with robotaxi services, Tesla must report any accident, system failure, or vehicle that becomes stranded on a Nevada road within five business days.

Tesla is entering a market Nevada already knows well. Zoox, the Amazon owned robotaxi company, has run its own autonomous vehicle permit in the state since last year, building up to roughly 100 vehicles and 350,000 rides along the Strip. That history likely explains why the NTA started Tesla at ten cars rather than the fleet size the company asked for. The agency has a template for scaling a permit up once a company proves out its safety record.

Tesla’s Nevada application first surfaced in June, when the company filed for the permit alongside plans for a maintenance hub in southwest Las Vegas. The company has said it won’t meaningfully scale its robotaxi fleet anywhere until FSD v15 ships, expected in late 2026 or early 2027, which makes the ten vehicle cap less of a constraint today than it might look on paper. For now, Tesla has the legal right to start Nevada rides. Whether it starts before FSD v15 arrives is a separate question the permit doesn’t answer.

Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.

Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.

Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.

The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.

Tesla announces 100k Powerwalls are participating in Virtual Power Plants

Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.

Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.

The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.

Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Elon Musk teases Tesla Roadster unveiling once again

Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.

A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”

Musk agreed:

The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.

It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:

“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”

The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.

However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.

For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”

We sure hope.
