NASA funds study on SpaceX BFR as option for massive space telescope launch

Published

Speaking at the Exoplanets II conference in Cambridge, UK July 6th, geophysicist and exoplanet hunter Dr. Debra Fischer briefly revealed that NASA had funded a study that would examine SpaceX’s next-gen BFR rocket as an option for launching LUVOIR, a massive space telescope expected to take the reigns of exoplanet research in the 2030s.

Conceptualized to follow in the footsteps of NASA’s current space telescope expertise and (hopefully) to learn from the many various mistakes made by their contractors, the LUVOIR (shorthand for Large UV/Optical/IR Surveyor) concept is currently grouped into two different categories, A and B. A is a full-scale, uncompromised telescope with an unfathomably vast 15-meter primary mirror and a sunshade with an area anywhere from 5000 to 20000 square meters (1-4 acres). B is a comparatively watered-down take on the broadband surveyor telescope, with a much smaller 8-meter primary mirror, likely accompanied by a similarly reduced sunshade (and price tag, presumably).

Remember, this is a space telescope that would need to fit into the payload fairing of a rocket, survive the launch into orbit, and then journey nearly one million miles from Earth to its final operational destination, all before deploying a mirror and starshade as large or larger than Mr Steven’s SpaceX  fairing recovery net. The James Webb Space Telescope (JWST), a rough successor to Hubble with a 6.5-meter primary mirror, is the only space telescope even remotely comparable to LUVOIR, and it has yet to launch after suffering a full decade of delays and almost inconceivable budget overruns. All we can do is hope that Northrop Grumman (primary contractor for JWST) is kept away from future giant space telescopes like LUVOIR.

The rocket problem

Nevertheless, the sheer scale of LUVOIR brings us back to an existential problem faced by all space telescopes – how to get into space in the first place. In this case, JWST offers a small taste of what launching such a large telescope requires, although it only truly applies the 8m LUVOIR B. The reason LUVOIR’s conceptual design was split into two sizes is specifically tied to the question of launch, with LUVOIR B’s 8m size cap dictated by the ~5 meter-diameter payload fairings prevalent and readily available in today’s launch industry.

LUVOIR A’s 15-meter mirror, however, would require an equally massive payload fairing. At least at the start, LUVOIR A was conceptualized with NASA’s Space Launch System (SLS) Block 2 as the launch vehicle, a similarly conceptual vehicle baselined with a truly massive 8.4 or 10-meter diameter payload fairing, much larger than anything flown to this day. However, the utterly unimpressive schedule performance of the SLS Block 1 development – let alone Block 1B or 2 – has undoubtedly sown more than a little doubt over the expectation of its availability for launching LUVOIR and other huge spacecraft. As a result, NASA has reportedly funded the exploration of alternative launch vehicles for the A version of LUVOIR – SpaceX’s Cargo BFR variant, in this case.

While only a maximum of 9 meters in diameter, the baselined cargo spaceship’s (BFS Cargo) payload bay has been estimated to have a usable volume of approximately 1500 cubic meters, comparing favorably to SLS’ 8.4 and 10-meter fairings with ~1000 to ~1700 cubic meters. The more traditional SLS fairing may offer more flexibility for minimizing complex deployment mechanisms for large telescopes (a sore spot for JWST), but SLS Block 2 is almost entirely up in the air at the moment, and liable to cost $5-10 billion alone to develop even after SLS Block 1 is flying (NET mid-2020). On the other hand, barring abject and total failure, SpaceX’s BFR rocket and spaceship could have many, many launches under its belt and a proven track record of reliability, whereas SLS Block 2 is unlikely to fly more than a handful of times ever, even if it gets built.

With any luck, the results of the LUVOIR SpaceX BFR launch analysis will make their way into the public sphere once the study is completed, perhaps revealing a few tidbits about the capabilities of the next-generation composite rocket. Another astrophysicist familiar with the project also noted that Blue Origin was firmly in the running of similar conceptual launch studies, hinting at a potential competition for commercial launches of each company’s massive future rockets.

California proposal to allow self-driving tests for heavy-duty trucks

A new proposal in the state of California would allow initial testing of self-driving heavy-duty trucks, as Tesla and others aim to bring their driverless technologies to market with Class 8 trucks and other large vehicles.

On Friday, the California Department of Motor Vehicles (DMV) said that it’s proposing self-driving vehicle tests be allowed on public roads for heavy-duty trucks and other large vehicles, as detailed in a report from Reuters. The news comes as heavy-duty vehicles about 10,001 pounds are currently unable to utilize public self-driving tests in California, as well as others such as Texas, Arizona, and Arkansas.

The proposal would restrict autonomous testing for semi-trucks and other oversized vehicles to specified, pre-selected routes that would be pre-determined to be legal for size, weight, and loading requirements. It would also ban testing these vehicles on city streets, with selected routes primarily including major highways.

The state would also prohibit testing of specific heavy-duty vehicles until further notice under the proposal, including household movers, commercial vehicles used to transport passengers, oversize loads, bulk liquids, or hazardous materials.

The DMV plans to hold a public hearing on the proposal on June 10, after which point it would be allowed to move forward with the agency.

California has been preparing regulations for autonomous trucking since at least last August, when the state submitted an initial draft for such a legal framework.

The state is also evaluating whether light-duty vehicle testing requirements should be updated. Currently, the state requires a permit to test self-driving vehicles utilizing a safety driver, before applying for subsequent phases of driverless testing and deployment permits.

To apply for driverless testing permits, manufacturers are required to conduct testing for a minimum of 50,000 miles, while heavy-duty manufacturers would be required to complete at least 500,000 autonomous testing miles under the proposal. Of them, up to 40,000 of the miles are allowed to be completed outside of California.

The news also follows the Trump administration’s aims to accelerate self-driving deployment this week through the expansion of exemptions for certain reporting requirements.

Although Tesla’s Full Self-Driving (FSD) is not currently available for the company’s electric Semi, it’s expected to become available at some point in the future. Tesla has also been spotted testing its FSD on the Semi in and around Giga Nevada, ahead of the company’s plans to launch the software on the Class 8 truck.

Tesla is currently aiming to ramp up production of the Semi, and it’s constructing an expansion to its Gigafactory in Nevada to eventually scale up to volume production.

Tesla reservation emails hint at imminent launch in India

Tesla appears to be nearing the launch of vehicle sales in India, as hinted at in a recent correspondence with early reservation holders.

A report this week says that Tesla has sent out a new batch of emails to some of its earliest reservation holders in India, suggesting that the company’s highly anticipated launch of electric vehicles (EVs) in the country could be imminent.

As seen in emails viewed by Bloomberg in a Friday report, Tesla has begun refunding early reservation holders in India, indicating that the U.S. automaker seems to be nearing its official debut in the country. Some Model 3 reservation holders in India initially paid deposits to purchase a Tesla as early as 2016, and they come due to the company having refreshed the vehicle’s design last year.

“We would like to return your reservation fee for the time being,” Tesla writes in the email. “When we finalize our offerings in India, we will reach out in the market again. We hope to see you back with us once we are ready to launch and deliver in your country.”

The launch is thought to be highly consequential for Tesla, as India is the world’s third-largest auto market, and thousands of people in the nation are employed by vehicle and component manufacturing facilities. However, years of talks between Tesla and the government about launching sales and potentially a factory there have hit a standstill multiple times, largely due to disagreements over the country’s high import duties.

While many are speculating as to when exactly Tesla could launch vehicle sales in India, several other indicators have also suggested that the maker is getting close to doing so.

Last weekend, a Tesla Model Y with a privacy wrap was seen being tested in India, marking the second such sighting to take place in the past few weeks. The company also officially began the certification and homologation processes for the new versions of both the Model Y and Model 3 in India last month, and it has been hiring and picked out two sites for initial stores in the country, the first in Mumbai and a second in New Delhi.

A Bloomberg report in February also claimed that Tesla was aiming to sell vehicles in India around the third quarter of the year, though models being sold in the country had not yet been revealed at the time.

Tesla’s Superchargers in North America opening to non-Tesla EVs

Along with allowing Tesla’s vehicles to charge at Supercharger stations, the company has slowly been rolling out access to other, non-Tesla electric vehicle (EV) brands in North America over the past several months. For example, Superchargers opened to Kia’s EVs in North America on Thursday, increasing the company’s chargers to the over 40,000 DC fast-charging stations and doubling the number of stations owners of the car brand can use.

Other brands with access to Tesla’s Superchargers include Kia parent company Hyundai, Ford, GM, Genesis, Lucid, Mercedes, Nissan, Polestar, Rivian, and Volvo, and Volkswagen and subsidiary Audi are the next brands in line to gain access.

Tesla also runs three-month Supercharger voting periods for owners to cast votes on where they’d like to see new Superchargers built, and the company recently opened its voting round for the second quarter along with revealing the winning locations from Q1.
