SpaceX’s Starship has flown a record 12.5 km into the air—and then crashed

https://www.technologyreview.com/2020/12/09/1013698/spacex-flies-starship-prototype-sn8-record-12-5-kilometers-into-the-air/

SpaceX today pulled off the first ever high-altitude (well, high-ish) flight of Starship, the rocket the company hopes will one day take humans to the moon and Mars. Although the spacecraft failed to make a safe landing—in fact, it exploded on impact—it’s the highest any Starship prototype has flown. Still well short of orbit, though, which is at least 160 kilometers (100 miles) up.

What happened: At around 4:40 p.m. US Central Time, Starship lifted off from the company’s test facility at Boca Chica, Texas. It reached a height of 12.5 kilometers and then descended in an attempt to land. But it came down too quickly and crashed, leaving smoldering wreckage. Total time in the air: 6 minutes and 42 seconds. 

This is the company’s eighth prototype of Starship (dubbed SN8). It flew substantially higher than the 150-meter “hop” the fifth iteration made in August and the sixth made in September—each with only one engine. (SN7 didn’t fly; it was exploded deliberately as part of a pressure test.) SpaceX founder Elon Musk had previously estimated only a one-third chance of success that SN8, armed with three engines, would safely fly and land. 

A giant among rockets: SpaceX first unveiled Starship to the world in September 2019, on the 11th anniversary of the company’s first rocket launch. It’s a behemoth, standing over 50 meters tall, and weighs over 1,400 tons (1,270 metric tons) when loaded with fuel. In its final form, the vehicle will double as a six-engine, second-stage booster that sits on top of a giant first-stage booster, the Super Heavy (currently under development). It will carry more than 100 tons of cargo and passengers to deep-space destinations. 

Like the company’s other major space vehicles, Starship is designed to be reusable, to lower the overall cost of spaceflight for robotic and crewed missions alike. 

What’s next: Musk has hinted on Twitter that the next two prototypes, SN9 and SN10, will also fly rather than be used for ground testing, but there have been no clues as to when. The company did not try to get Starship into orbit this year but will likely try in 2021. Musk said in early December that he was “highly confident” SpaceX would send people to to Mars in 2026, or even in 2024 “if we get lucky.”

SoftBank has reportedly sold Boston Dynamics to Hyundai

https://www.engadget.com/softbank-boston-dynamics-hyundai-motors-sale-080541059.html

Hyundai Motors is acquiring Boston Dynamics, according to The Korea Economic Daily. The publication says Softbank has agreed to sell the robot maker for 1 trillion won (US$917 million) and that the acquisition will be finalized at a board meeting today, December 10th. The companies have been discussing a sale since at least early November, based on a previous report by Bloomberg.

Boston Dynamics is known for its nightmare-inducing (or oddly adorable, depending on your perspective) robotic dog Spot, which it started selling in mid—2020 for $75,000. The four-legged robot can climb stairs, herd sheep and pull a rickshaw. Earlier this year, the machine also helped healthcare providers remotely triage patients suspected to have COVID-19 at Boston’s Brigham and Women’s Hospital. The company is also behind the humanoid robot Atlas that’s agile enough to do handstands and parkour.

Boston Dynamics is a Massachusetts Institute of Technology spinoff first acquired by Google in 2013. In 2017, Google’s parent company Alphabet sold it to Softbank, which had a “vision of catalyzing the next wave of smart robotics.” Hyundai Motor has been investing heavily in robotics over the past couple of years and vowed to invest up to 1.5 trillion won (US$1.4 billion) in the industry by 2025. It has mostly focused on manufacturing wheeled robots for factory use, though, instead designing machines as interesting as Spot and Atlas. KED says Hyundai Motor will shoulder about 400 billion won, while its affiliates, including auto parts maker Hyundai Mobis Co. will pay the rest of the acquisition price.
