SpaceX looks to launch space tourists to record heights

Published

on

SpaceX has signed an agreement with a space tourism company that could see its Crew Dragon spacecraft take space tourists to heights unmatched by astronauts in half a century.

On Tuesday, February 18th, Space Adventures announced the agreement, revealing that it is now officially looking for wealthy private customers interested in launching to orbit on a SpaceX rocket and spacecraft. Known as Crew Dragon, that spacecraft is perhaps just two or three months away from SpaceX’s inaugural astronaut launch, in which two NASA astronauts will be sent into orbit to rendezvous and dock with the International Space Station (ISS) before returning to Earth after several weeks or months in space.

Founded in 1998, while Space Adventures has a slightly checkered past and has been more or less inactive for more than a decade, the company did manage to arrange eight separate spaceflights for seven private customers between 2001 and 2009. All flights previously arranged were done so through Russian space agency Roscosmos with Soyuz rockets and spacecraft and involved approximately week-long visits to the International Space Station (ISS), where the private astronauts – all multimillionaires and billionaires – mainly observed routine ISS operations and assisted with science experiments. With SpaceX’s Falcon 9 and Crew Dragon, Space Adventures hopes to soon offer orbital tourists an option that keeps all operations in the United States.

As noted, it must be stated that the February 18th agreement doesn’t actually mean that private customers will definitively launch into orbit in SpaceX’s Crew Dragon spacecraft. Instead, it serves as a semi-contractual confirmation that the spaceflight company is officially willing and ready to support such a mission in the event that Space Adventures is able to secure enough customers to purchase the necessary launch services. While not out of the question, that will be no easy feat.

Thankfully, several aspects of this new agreement should work in SpaceX and Space Adventures’ favor. As a unique ‘free-flying’ mission, Crew Dragon and its space tourists would not actually rendezvous with the ISS – instead serving as its own miniature outpost in Low Earth Orbit (LEO) for several days. Relative to SA’s past tourist flights to the ISS, this will save a large portion of the time and cost associated with both training civilians for spaceflight and ISS operations and working with NASA and Roscosmos to arrange the complex mission.

Aside from simplifying the training and bureaucracy involved in orbital tourism, the fact that Space Adventures’ newest proposal will have no affiliation or involvement with NASA or Roscosmos also means that there’s nothing preventing SpaceX from using a flight-proven Falcon 9 booster and Crew Dragon capsule on its space tourist launch. By combining flight-proven hardware with a space station-free mission profile, SpaceX could theoretically cut the overall flight’s cost by tens or even hundreds of millions of dollars.

According to public analyses performed over the last few years by auditors and researchers, SpaceX Crew Dragon launches will likely cost NASA around $400 million each, while a comparable Boeing Starliner mission will cost the space agency at least $650 million. The SpaceX figure is, however, predicated upon the production of a brand new Falcon 9 rocket and Crew Dragon spacecraft for each launch and includes costs associated with any processing or operations involving NASA teams and facilities.

As noted above, the use of a thoroughly flight-proven Falcon 9 booster and Crew Dragon capsule could dramatically cut the cost of private astronaut launches relative to the NASA baseline. It’s conceivable that – having effectively amortized the cost of the spacecraft and booster with a NASA astronaut launch – such a private mission’s price could be little more than the cost of building a new Falcon upper stage and Crew Dragon trunk, as well as booster/capsule refurbishment and general operations. Conservatively, the ultimate price SpaceX offers or offered Space Adventures could thus be as low as $100-200 million per launch.

Space Adventures says it could support as many as four space tourists on one flight, translating to a cost of $25-50 million per person if all seats are filled. This would compare reasonably well with the $20-50 million it typically charged its seven orbital tourism customers. That is still a vast sum of money and cuts the pool of potential customers to perhaps a few tens of thousands of people worldwide. Nevertheless, Google co-founder Sergey Brin (and possibly others) is on a sort of waiting list (requiring a $5 million deposit) for future orbital Space Adventures flights, giving the company at least one strong prospective customer.

Thanks to skipping a space station rendezvous, perhaps the single biggest selling point of the mission is that Falcon 9 and Crew Dragon could potentially send space tourists higher than ever before – to an altitude only certain NASA Apollo and Gemini astronauts can claim to have surpassed. Space Adventures specifically notes this on its website, stating that prospective space tourists could reach an altitude that only Gemini 11 astronauts have surpassed while remaining in Earth orbit.

Gemini 11 astronauts reached an of apogee around 850 miles (1350 km) while still in Earth orbit – a record that stands today. Neither Space Adventures or SpaceX have specifically stated how high an unmodified Falcon 9 and Crew Dragon to launch private astronauts, but the implication is that the view would be comparable to – or even better than – what the Gemini 11 crew saw back in 1966. Regardless, it’s safe to say that if SpaceX and Space Adventures’ new space tourism effort is greeted with healthy demand, we’ll be shortly entering a new era of private spaceflight. Crew Dragon’s first private astronaut mission is tentatively scheduled to launch as early as late-2021 or early-2022.

Why Tesla Roadster unveiling delay might have nothing to do with it flying

Published

Tesla announced on Monday that the Roadster event scheduled for today would be postponed due to the need for it to be held outside.

Less than 24 hours later, CEO Elon Musk broadened that by stating it was due to high winds, immediately sending everyone into a frenzy over the Roadster’s potential ability to fly.

And realistically, it could definitely have to do with it flying, hovering, or hopping; whatever Tesla has in mind for this demonstration could not be impacted by wind. However, it might have nothing to do with the vehicle flying whatsoever, and instead could be a simple precaution, as the Roadster is a very unique vehicle with some already official specs that are just mind-blowing.

Tesla will very, very likely be showcasing both the acceleration rate and potentially even a top speed demo at the event in Waco. Both of these demonstrations, performed with a vehicle that has such incredibly fast metrics, could easily be impacted by wind as well.

Tesla Roadster event requires restricted airspace, and the FAA obliges

Top Speed Demo

At high speeds, aerodynamic forces are already overwhelmingly present. A crosswind or sudden gust adds a layer of sideways force that the tires must counter with slip angle. On a short demo course, that force can shove the car off the intended line, especially in a light car with a low frontal area and little mass to resist the push.

Electric cars, due to their battery packs, have an advantage of an extremely low center of gravity, giving them extra stability. However, the speeds at which the Roadster could travel at the demo could spell some issues if crosswinds are present.

Gusts are worse than a steady wind because the load changes faster than a driver can smoothly correct. That shows up as weaving or a late correction. Headwinds and tailwinds can also spell disaster. Headwinds cut a measured top speed but raise the power needed to get there or maintain it. Meanwhile, a tailwind can inflate the top speed, and downforce issues could become more noticeable.

Wind also loads the body unevenly. A low car can feel light on the upwind side or see a sudden change in downforce if the gust hits a wing or diffuser at an angle. Tire temperature and pressure might stay near a normal level, but lateral grip can be lost as the vehicle is spent fighting the wind.

Acceleration Demo

Launch and 0-60 MPH runs are shorter, so the car spends less time exposed to forces that could cause things to go awry. However, the first second is very sensitive, as a crosswind at launch could yaw the car before speed builds and prior to aerodynamic impact being too great. The driver will be required to correct traction control or manage how much the wheels are spinning, which will likely be corrected automatically by some sort of traction control system within the Roadster (we are fairly certain Tesla will implement something brilliant with it).

These things could cause an unstable run.

A headwind would increase drag as speed rises, while a tailwind would do the opposite. Meanwhile, surface effects, like wind-driven dust, light debris, or even rain, could reduce grip at the exact moment the tires are asked for peak longitudinal force. Standing water plus a crosswind is a common reason an acceleration attempt might be scrapped.

Flying or Not

No matter what Tesla has in store for the Roadster, waiting for ideal conditions is a great idea. People who follow and support the company, along with the engineers involved in the Roadster program, have been waiting nine years since the last unveiling for this moment. Everything should be ideal.

Some speculate that it’s just not ready, and that’s ridiculous. Why would Tesla even schedule the event — albeit prematurely — after nine years if it was not ready? Why would they jump the gun now?

We were all excited for today, but it truly is the most ideal thing in the world to wait two more weeks so everything, including the weather, can be perfect. The delay is simply worth it. But Tesla, seriously, make this the last one.

SpaceX nails “Lucky 13” astronaut launch, leaning into Tesla tradition and superstition

SpaceX launched Crew-13 astronauts to the ISS Thursday, setting up a record fast Dragon docking.

SpaceX launched NASA’s Crew-13 mission to the International Space Station on Thursday morning, getting four astronauts to orbit despite a forecast of thunderstorms and gusty winds that had threatened to push the flight to Friday.

Falcon 9 lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station at 11:10 a.m. ET carrying Dragon Grace, NASA confirmed. On board are NASA commander Jessica Watkins, NASA pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov. The first stage booster, B1101, landed at Landing Zone 40 beside the pad on its third flight after previously supporting Crew-12 and a Starlink mission.

It was the first spaceflight for Delaney, Kutryk and Teteryatnikov. Watkins, who flew on Crew-4 in 2022, became the first NASA astronaut to launch aboard a Crew Dragon twice.

Before launch, the crew rode to the pad in Teslas, a tradition on NASA’s SpaceX crew flights since 2020. This time the cars carried specialty plates reading “Lucky 13.” Watkins said the mission patch leans into the number on purpose, as a nod to Apollo 13 and the resilience of that crew.

Grace is now on a short trip to the station. Docking at the forward port of the Harmony module is scheduled for about 7 p.m. ET, roughly 7 hours and 50 minutes after liftoff, which Space.com notes would be the fastest Crew Dragon transit to the ISS yet. Most Dragon flights take around 15 to 24 hours to catch the station. Hatch opening is planned for 8:25 p.m. ET.

The launch came more than two weeks later than originally planned. An oxidizer leak was found in Grace’s propulsion system in August, and NASA and SpaceX added time for tests. That pushed back the return of Crew-12, which has been aboard the station since February and is now set to splash down off Southern California next week. Crew-13 is expected to stay about six months.

SpaceX rescue mission for stranded ISS astronauts nears end — Here’s when they’ll return home

SpaceX already holds NASA orders for crew rotations through Crew-17, while Boeing is preparing an uncrewed Starliner flight to the station as early as December.

Crew-13 was only the first of three SpaceX launches planned for Thursday, as Teslarati previewed on Wednesday. A Falcon 9 launched its Transporter-18 mission from California today, where Google will be launching its first orbital artificial intelligence (AI) test satellite. Meanwhile, Falcon Heavy is set to launch the classified NROL-97 mission for the National Reconnaissance Office from Launch Complex 39A at 11:53 p.m. ET. Its two side boosters will return to Landing Zones 1 and 2, which means Central Florida could hear up to three sonic booms in a single day. The busy stretch follows Starship’s Flight 14 on Monday, which reached orbit for the first time.

Tesla moves forward on Wireless Charging for vehicles

Tesla has moved its Wireless Charging efforts for its electric vehicles forward, as it had a new patent published today, one that it submitted back in March.

The patent describes a system for detecting foreign objects on the wireless charging pad under varying temperatures, aiming to mitigate any undesired results that could come from something being on top of the charging pad.

The abstract of the patent states:

“The present disclosure relates to methods and systems that can reliably detect foreign objects on a wireless charging pad under varying temperatures. In some examples, an object detector can utilize a set of inductive coils included in resonant tanks, and excite the resonant tanks using signals in a range of frequencies including or near a nominal resonant frequency of the resonant tanks. The object detector can detect a metal object based on resistance of a coil increasing and inductance of the coil decreasing. By analyzing the shifts and/or distributions in resonant frequencies and output magnitudes (e.g., output voltage peaks), the object detector can distinguish between changes of frequencies and magnitudes caused by temperature and those caused by foreign objects to accurately detect the foreign objects.”

The object detection system will utilize a set of inductive coils included in resonant tanks, and “excite the resonant tank using signals in a range of frequencies including or near a nominal resonant frequency of the tanks.” Metal can be detected by an increase in the coil’s resistance and a decrease in the coil’s inductance.

By analyzing shifts or disruptions in resonant frequencies and output magnitudes, the system can detect foreign objects. These types of safeguards need to be implemented through the normal operation of the charging pads.

Tesla says its Cybercab wireless charging efficiency is ‘well above 90%’

Tesla plans to utilize wireless charging with Cybercab and Robotaxi-enabled units to help streamline the fully autonomous experience from A to Z. The last thing the company wants to do is have any sort of small obstruction preventing the rider from experiencing Robotaxi as intended.
