Just a year and a half after sending NASA’s Parker Solar Probe to study the Sun, United Launch Alliance (ULA) is ready to once again support a science mission on its way to the center of our solar system. The Solar Orbiter, a unique spacecraft jointly developed by NASA and the European Space Agency, will launch aboard a ULA Atlas V 411 booster, propelling it to the Sun to snap the first photos of its north and south poles.

The Solar Orbiter will work in conjunction with NASA’s Parker Solar Probe in unlocking the mysteries of our closest star. Parker Solar Probe occasionally dips into the Sun’s atmosphere – referred to as the corona – learning about the environment and the solar wind that propels energy and radiation into our solar system. The Solar Orbiter will – as the name suggests – orbit the Sun, but will remain further away than Parker (about 26 million miles away) allowing it to produce the first images of the Sun’s northern and southern poles. This advancement could potentially offer more insight into the Sun’s powerful magnetic field.

The ULA Atlas V 411 booster arrived in Florida back in November 2019. Since the completion of the previous Atlas V mission that supported the Boeing Starliner Orbital Flight Test in December 2019, ULA has been continuously prepping for the launch of the Solar Orbiter. In early January 2020, the booster was vertically hoisted into ULA’s Vertical Integration Facility. Following final booster preparations, including rolling it out to the launchpad for pre-launch testing twice, the safely encapsulated Solar Orbiter payload was carefully stacked on top during final integration on January 31st.

According to ULA, the Atlas V 411 configuration was selected to provide the necessary “Earth departure trajectory for making repeated close encounters with the sun.” The configuration used to launch the Solar Orbiter consists of a dual-nozzle main engine and one solid-fuel booster mounted to the side. This allows the rocket to utilize steering capability provided by the main engine while maintaining a center of gravity stabilized by the additional booster. ULA states that while this is a rather unique configuration, it is one that has been successfully utilized to support missions five times since 2006.

Ahead of the February 9th launch attempt, teams rolled the mighty Atlas V 411 out to the launchpad at Space Launch Complex-41 at Cape Canaveral Air Force Station to complete a full Wet Dress Rehearsal (WDR) – a full run-through of launch day operations including fueling the rocket and proceeding through terminal count. The first attempt at WDR resulted in a minor delay of launch due to a “wind-blown ECS cold air duct” that had to be replaced before testing could be completed, according to CEO of ULA, Tory Bruno. The second attempt of the WDR on January 24th was completed without a hitch.

On Friday morning February 7th, Bruno announced that all of pre-flight rehearsals and verifications were completed and the Solar Orbiter was ready to begin its journey to the Sun.

Currently, ULA and NASA are targeting a launch on Sunday, February 9th at 11:03 pm EST (0403 UTC) with a two-hour launch window. The launch weather is at 80% “GO” conditions with cumulus clouds as the primary concern for violation. Should the launch need to 24-hr recycle for a launch attempt on Monday, February 10th, weather conditions deteriorate slightly to 70% “GO.”

ARK’s SpaceX IPO Guide makes a compelling case on why $1.75T may not be the ceiling

ARK Invest breaks down six reasons SpaceX’s $1.75 trillion IPO valuation may be justified.

Published

on

By

ARK Invest, which holds SpaceX as its largest Venture Fund position at 17% of net assets, has published a detailed investor guide to why a SpaceX IPO may be grounded in a $1.75 trillion target valuation.

The financial case starts with Starlink, SpaceX’s satellite internet constellation, which has surpassed 10 million active subscribers globally as of early 2026, with 2026 revenue projected to exceed $20 billion. ARK’s research puts the total satellite connectivity market opportunity at roughly $160 billion annually at scale, and Starlink is adding customers faster than any telecom network in history. That growth alone would justify a substantial valuation.

Additionally,  ARK notes that SpaceX has reduced the cost per kilogram to orbit from roughly $15,600 in 2008 to under $1,000 today through reusable Falcon 9 hardware. A fully operational Starship targeting sub-$100 per kilogram would represent a significant cost decline and open markets that do not currently exist. SpaceX executed a staggering 165 missions in 2025 and now accounts for approximately 85% of all global orbital launches. That infrastructure position took decades to build and would be nearly impossible to replicate at comparable cost.

SpaceX officially acquires xAI, merging rockets with AI expertise

The February 2026 merger with xAI added a layer to the valuation that straightforward financial models struggle to capture. ARK argues that at sub-$100 launch costs, orbital data centers could deliver compute roughly 25% cheaper than ground-based alternatives, without power grid delays, permitting friction, or land constraints. Musk has stated a goal of deploying 100 gigawatts of AI computing capacity per year from orbit.

The $1.75 trillion figure itself is not a conventional earnings multiple. At roughly 95x trailing revenue, it prices in Starlink’s adoption curve, Starship’s cost trajectory, and the orbital compute thesis together. The public S-1 prospectus, due at least 15 days before the June roadshow, will give investors their first complete look at the financials to test those assumptions. ARK’s position is that the track record earns the benefit of the doubt. Fully reusable rockets were considered unrealistic for years. Starlink was considered financially unviable. Both happened on timelines that surprised skeptics.

Ford CEO Farley says Tesla is not who to look at for EV expertise

Interestingly, Farley has been one of the most hellbent CEOs in terms of a legacy automaker standpoint to push the EV effort. It did not go according to plan, as Ford took a $19.5 billion charge and retreated from its EV push in late 2025.

Ford CEO Jim Farley said in a recent podcast interview that Tesla is not who Americans should look at to beat Chinese carmakers.

The comments have sparked quite a bit of outrage from Tesla fans on X, the social media platform owned by Elon Musk.

Farley said that Chinese automakers are better examples of how to beat competitors. He said (via the Rapid Response Podcast):

“If you’re an American and you want us to beat the Chinese in the car business, you’re all going to want to pay attention, not necessarily to Tesla. Nothing against Tesla—they’ve been doing great—but they really don’t have an updated vehicle. The best in the business for us, cost-wise and competition-wise, supply chain, manufacturing expertise, and the I.P. in the vehicle, was really BYD. In this next cycle of EV customers in the U.S., they want pickups and utilities and all these different body styles. But they want them at $30,000, not $50,000. Like the first inning, they want them affordably.”

Despite Farley’s synopsis, it is worth mentioning that Tesla had the best-selling passenger vehicle in the world last year, and in China in March, as the Model Y continued its global dominance over other vehicles.

Musk responded to Farley’s comments by stating:

“This is before Supervised FSD is approved in China. Limiting factor is production output in Shanghai.”

Interestingly, Farley has been one of the most hellbent CEOs in terms of a legacy automaker standpoint to push the EV effort. It did not go according to plan, as Ford took a $19.5 billion charge and retreated from its EV push in late 2025.

Instead, Ford is “doubling down on its affordable” EVs and said it would pivot from its previous plans.

Reaction from Tesla fans was pretty much how you would expect. Many said they have lost a lot of respect for Farley after his comments; others believe he is the last CEO anyone should be taking advice on EVs from.

Nevertheless, Farley’s plans are bold and brash; many consider Tesla the most ideal company to replicate EV efforts from. It will be interesting to see if Ford can rebound from this big adjustment, and hopefully, Farley’s plans to replicate efforts from BYD work out the way he hopes.

SpaceX wins its first MARS contract but it comes with a catch

NASA awarded SpaceX a $175 million Mars rover contract while the White House proposes cutting the mission.

Published

NASA just signed a $175.7 million contract with SpaceX to launch a Mars rover that the White House is simultaneously trying to defund. The contract, awarded on April 16, 2026, tasks SpaceX’s Falcon Heavy with launching the European Space Agency’s (ESA) Rosalind Franklin rover from Kennedy Space Center in Florida, no earlier than late 2028. It would mark the first time SpaceX has ever sent a payload to Mars.

Under NASA’s Rosalind Franklin Support and Augmentation project, known as ROSA, the agency is providing braking engines for the rover’s descent stage, radioisotope heater units that use decaying plutonium to keep the rover warm on the Martian surface, additional electronics, and a mass spectrometer instrument, as noted by SpaceNews.

Those nuclear heating units are the reason an American rocket was required at all. U.S. export controls on radioisotope technology mean any payload carrying them must launch on a domestic vehicle, which narrowed the field to SpaceX and United Launch Alliance. Falcon Heavy’s pricing made it the practical choice.

SpaceX is quietly becoming the U.S. Military’s only reliable rocket

Falcon Heavy debuted in February 2018 and has 11 launches to its record. The rocket has not flown since October 2024, when it sent NASA’s Europa Clipper toward Jupiter. The three-core design, built from modified Falcon 9 first stages, gives it the lift capacity needed for deep space planetary missions that a single Falcon 9 cannot reach.

The Rosalind Franklin rover has been sitting in storage in Europe for years. It was originally due to launch in 2022 as a joint mission with Russia, but Russia’s invasion of Ukraine ended that partnership, leaving the rover built but stranded without a launch vehicle or landing hardware. NASA stepped back in through a 2024 agreement with ESA to rescue the mission. The rover is designed to drill up to two meters below the Martian surface in search of evidence of past life, a science objective no previous mission has attempted at that depth.

The contradiction at the center of this story is hard to ignore. The White House’s fiscal year 2027 budget proposal included no funding for ROSA and did not mention the mission at all in the detailed congressional justification document released April 3.

Musk has long argued that reaching Mars is not optional. “We don’t want to be one of those single planet species, we want to be a multi-planet species.” Whether this particular mission survives Washington’s budget fight, the Falcon Heavy contract means SpaceX is now formally on record as the rocket that could get humanity’s next Mars science mission off the ground.

The timing of this contract carries extra weight given that SpaceX filed confidentially with the SEC in early April and is targeting an IPO roadshow in the week of June 8. It would be the largest public offering in history.
