Just shy of two months into 2019, the new year has been marked by a distinct focus on human spaceflight. Most of that focus has centered (as it should) on the relatively imminent launch debut of both SpaceX’s Crew Dragon and Boeing’s Starliner, crewed spacecraft designed and built to carry astronauts into orbit for NASA.

However, beyond SpaceX and Boeing, a considerable amount of noise is being made about the labors and relative progress of companies like Blue Origin and Virgin Galactic, both primarily focused on building a suborbital tourism market with their New Shepard and SpaceShipTwo launch vehicles. Coming as no surprise from companies aiming to create a sustainable market for a very expensive consumer product, both products have been dragged through a torturous maze of marketing hype in a process that has not really done the serious endeavor of human spaceflight any favors.

The Shepard and the Ship

  • Virgin Galactic’s launch vehicle provider The Spaceship Company has been working to develop a suborbital platform to launch humans since the early 2000s, incorporated after billionaire Paul Allen funded a group of companies that ultimately won the Ansari X Prize in 2004.
    • The Virgin/TSC approach involves a carrier aircraft (Known as White Knight Two) and a much smaller rocket plane (SpaceShipTwo) that is carried up to ~30,000 feet (9 km) before dropping and igniting its engine.
    • SpaceShipTwo is meant to reach a maximum altitude of around 300,000 feet (~90 km) at a top speed of roughly Mach 3 (1000 m/s, 2200 mph) before gliding back to land on the same runway.
    • In 2014, a combination of bad aeronautical design and pilot error triggered the in-flight failure of the first SpaceShipTwo, killing one of its two pilots. A member of the NTSB board that investigated the failure stated that Scale Composites (one of TSC’s parent companies) “put all their eggs in the basket of the pilots [flying the vehicle] correctly.”
    • In a February 2019 video, Virgin Galactic CEO George Whitesides noted that “many aircraft are moving to being less piloted over time [but] our vehicle really is piloted to space.”
    • SpaceShipTwo most recently launched on February 22nd.
  • Blue Origin has yet to launch an actual human on New Shepard, a small, reusable single-stage rocket designed to loft a separate passenger capsule to approximately 100 km (330,000 ft).
    • New Shepard has conducted ten launches since its 2015 debut, most of which saw the crew capsule and booster approximately reach that nominal 100 km apogee and nine of which concluded with a successful landing of the rocket’s booster.
    • Capable of carrying up to six passengers, the Crew Capsule features a built-in abort motor that has been successfully tested, as well as a parachute system for a relatively soft landing at end-of-mission.

“Spacecraft” and “astronauts”

  • Aside from the generally impressive technology itself and the undeniable challenges and risks of launch humans on fueled rockets, both Blue Origin’s New Shepard and Virgin Galactic’s SpaceShipTwo exist – albeit with different weights – to cater to a new market, suborbital or “space” tourism.
    • While NASA is taking advantage of the opportunities to test small experiments with both vehicles as a partial platform, the real goal of both vehicles is to routinely launch paying customers.
    • While Blue Origin has yet to announce ticket pricing, Virgin Galactic has priced their offering at $250,000 per person. In both cases, the end result will likely be a six-figure sum in return for an experience that should last no more than 10-60 minutes from start to finish, excluding buildup from screening and whatever training is deemed necessary.
    • In other words, short of cases involving charity, tickets on New Shepard and SpaceShipTwo will almost indefinitely be reserved for less than 1% of humanity, those with income around $1M or more per year. This is by no means a bad thing and is, in fact, a proven first or second step in the direction of democratizing exotic or expensive technologies like air travel, computers, and even electric cars (namely Teslas).
  • However, both companies are laser-focused on branding their vehicles as spacecraft and their passengers as astronauts, with Virgin Galactic being the worst offender in this regard.
    • Aside from literally calling its 600+ prospective customers “Future Astronauts”, Virgin Galactic uses every chance it gets to hammer home its claim that SpaceShipTwo is a commercial spacecraft and its pilots true licensed, “wing”-ed astronauts.
    • While passengers are not eligible for official FAA ‘astronauts’ wings’, it appears that Virgin will continue to market its passenger experience as one where customers will get to ‘travel to space’ and more or less become astronauts.
    • Blue Origin describes its commercial offering as a “reusable suborbital rocket system designed to take astronauts and research payloads past the Kármán line – the internationally recognized boundary of space.”
    • Both Blue and Virgin flights offer about ~4 minutes of weighlessness between launch and landing.
  •  

    • For context, Alan Shepard – the US test pilot and namesake of New Shepard – was launched to an altitude of almost 190 km (120 mi) for what was recognized as the first US “spaceflight” and spent something like 5-10 minutes in microgravity and above the Karman Line (100 km).
    • Used as a rough measure for a sort of fixed, arbitrary boundary between “Earth” and “Space”, reasonable arguments have been made in the last few years that the 100 km Karman Line could more accurately be placed around 70-90 km, in which case Virgin Galactic might actually be technically correct when saying that SpaceShipTwo and its passengers are traveling to space.
      • Fewer than 570 humans in all of history have visited space (> 100 km), around 99.5% of which were astronauts that reached orbit. To call pilots of a spaceplane as distinctly suborbital as SpaceShipOne “astronauts” is palatable, particularly given the risks they face as test subjects and test pilots.
      • However, to even hinting that tourists riding New Shepard or SpaceShipTwo to altitudes of ~80-100 kilometers are astronauts would do an immense disservice to those that pushed the limits of technology, risked their lives, or even died in pursuit of orbital spaceflight, the only kind of spaceflight with any significant utility.
    • Much like cruise ship customers are not under the impression that they are coming along to ‘become sailors’, suborbital tourists are not astronauts. That being said, it’s not inaccurate to describe the experience they will have the privilege of being part of as something truly extraordinary, given that they will become one of a very select few humans to have actually launched on a rocket or seen the exaggerated curvature of Earth’s limb against the blackness of space.

    Mission Updates 

    • SpaceX’s first attempted orbital launch of Crew Dragon – a spacecraft designed to transport astronauts to and from the International Space Station – is set to occur as early as 2:49 am EST/07:49 UTC on March 2nd.
      • This is the first truly serious date, thanks to the successful completion of a critical pre-launch review conducted by NASA and SpaceX.
    • The second launch of Falcon Heavy could occur as early as late March
    • Aside from DM-1 and Falcon Heavy Flight 2, it’s unclear what SpaceX mission will happen next, although a West Coast launch (the Radarsat Constellation Mission) is a strong candidate.

    After successfully sending the world’s first commercial lunar lander on its way to the Moon and placing Indonesian communications satellite PSN-6 in a high-energy Earth orbit, Falcon 9 B1048 completed its third launch and landing and returned to port on February 24th. The booster’s fourth mission, a Crew Dragon in-flight abort test, will likely destroy B1048, making this its last successful recovery. (c. Tom Cross)

SpaceX is preparing to launch the tenth test flight of its Starship vehicle as early as Sunday, August 24, with the launch window opening at 6:30 p.m. CT. 

The mission follows investigations into anomalies from earlier flights, including the loss of Starship on its ninth test and a Ship 36 static fire issue. SpaceX has since implemented hardware and operational changes aimed at improving Starship’s reliability.

Booster landing burns and flight experiments

The upcoming Starship Flight 10 will expand Super Heavy’s flight envelope with multiple landing burn trials. Following stage separation, the booster will attempt a controlled flip and boostback burn before heading to an offshore splashdown in the Gulf of America. One of the three center engines typically used for landing will be intentionally disabled, allowing engineers to evaluate whether a backup engine can complete the maneuver, according to a post from SpaceX.

The booster will also transition to a two-engine configuration for the final phase, hovering briefly above the water before shutdown and drop. These experiments are designed to simulate off-nominal scenarios and generate real-world data on performance under varying conditions, while maximizing propellant use during ascent to enable heavier payloads.

Starship upper stage reentry tests

The Starship upper stage will attempt multiple in-space objectives, including deployment of eight Starlink simulators and a planned Raptor engine relight. SpaceX will also continue testing reentry systems with several modifications. A section of thermal protection tiles has been removed to expose vulnerable areas, while new metallic tile designs, including one with active cooling, will be trialed.

Catch fittings have been installed to evaluate their thermal and structural performance, and adjustments to the tile line will address hot spots observed on Flight 6. The reentry profile is expected to push the structural limits of Starship’s rear flaps at maximum entry pressure.

SpaceX says lessons from these tests are critical to refining the next-generation Starship and Super Heavy vehicles. With Starfactory production ramping in Texas and new launch infrastructure under development in Florida, the company is pushing to hit its goal of achieving a fully reusable orbital launch system.

Elon Musk takes aim at Bill Gates’ Microsoft with new AI venture “Macrohard”

It is quite an appropriate name for a company that’s designed to rival Microsoft.

Elon Musk has set his sights on Microsoft with a new company called “Macrohard,” a software venture tied to his AI startup, xAI. 

Musk described the project as a “purely AI software company” that’s designed to generate hundreds of specialized coding and generative AI agents that could one day simulate products from companies like Microsoft entirely through artificial intelligence.

Macrohard‘s Purpose

Musk announced Macrohard on Friday, though xAI had already registered the trademark with the US Patent Office a few weeks ago, as noted in a PC Mag report. Interestingly enough, this is not the first time that Musk has mentioned such an initiative.

Just last month, he stated that xAI was “creating a multi-agent AI software company, where Grok spawns hundreds of specialized coding and image/video generation/understanding agents all working together and then emulates humans interacting with the software in virtual machines until the result is excellent.”

At the time, Musk stated that “This is a macro challenge and a hard problem with stiff competition,” hinting at the venture’s “Macrohard” moniker. A few years ago, Musk also posted “Macrohard >> Microsoft” on X.

Powered by xAI and Colossus

Macrohard appears to be closely linked to xAI’s Colossus 2 supercomputer project in Memphis. Musk has confirmed plans to acquire millions of Nvidia GPUs, joining rivals such as OpenAI and Meta in a high-stakes race for AI computing power. Colossus is already one of the most powerful supercomputer clusters in the world, and it is still being expanded.

xAI is only a couple of years old, having been founded in March 2023. During its Engineering Open House event in San Francisco, Elon Musk highlighted that the company’s speed will be its primary competitive edge. “No SR-71 Blackbird was ever shot down and it only had one strategy: to accelerate,” Musk said.

Elon Musk confirms he’s still in wartime CEO mode

He is still locked in.

Elon Musk tends to use social media platform X as his personal platform to express himself, so much so that critics tend to allege that the CEO is no longer serious about his numerous companies. 

As per Musk, he is still very much in wartime CEO mode, despite all the jokes and fun posts about Ani on X. 

Elon Musk leads several prolific companies, much more than the average CEO. And while Tesla is the only publicly traded entity that he currently leads, Musk is so visible that everyone across the internet pretty much has a strong opinion of him one way or another. For his longtime supporters and followers, however, what truly matters is if Musk is locked in.

Considering that Elon Musk’s feed on X has recently been filled with AI imagery, a good portion of which involve AI-rendered women, some X users have expressed concerns that the CEO may be losing focus once more. Musk responded to one such user by highlighting his very busy schedule and his numerous active projects. 

Needless to say, Elon Musk is still locked in. He is still in “wartime CEO” mode.

As per the CEO, even his recent AI posts about AI are “part of a broader vision and strategy.” He also highlighted that SpaceX’s Starship Flight 10 is launching in a few days, xAI’s Grok 5 is starting its training next month, and Tesla’s Autopilot V14 is also coming next month. As per Musk, “long-term strategy is compelling.”

Elon Musk’s comments are quite accurate. While he may seem to spend all his time on X, after all, he is very much still neck-deep in all his companies’ projects. There is a reason why Musk became known as a visionary, and a lot of it is because he really is intimately involved in all of his companies’ projects.
