Japanese billionaire Yusaku Maezawa’s search for a girlfriend to join him on a voyage around the moon will be the subject of a new documentary program, in the latest attention-grabbing stunt by the entrepreneur.
44-year-old Maezawa, who sold his online fashion retailer Zozo Inc to SoftBank Group Corp, is seeking single females aged over 20 for the show, which will be shown on streaming service AbemaTV.

Electric thrusters for spacecraft are increasingly shrinking, and could prove key for new space missions. And, according to two novel space tech companies, Phase Four and Accion Systems, they might even go interplanetary.
Conventional rockets that rely on chemical reactions “are a great way to generate a lot of thrust, but they are very inefficient when it comes to generating thrust given the amount of propellant they carry,” Simon Halpern, founder and CEO of space propulsion company Phase Four in El Segundo, California, told Space.com. “That’s why launching even a small satellite requires a gigantic multistory rocket.”
Scientists have explored a variety of alternatives to chemical rockets over the years. One is electric propulsion, which generates thrust by using electricity to accelerate electrically charged propellants away from a spacecraft. [Wild Ideas for Superfast Space Propulsion].
Live coverage of SpaceX’s preparations for the next Falcon 9 rocket launch from pad 39A at NASA’s Kennedy Space Center in Florida. The mission will loft an unpiloted Crew Dragon spacecraft on a high-altitude test of the capsule’s launch abort system. Text updates will appear automatically below. Follow us on Twitter.
Now, DOD is leading a new charge, pouring more than $1 billion annually into hypersonic research. Competition from ambitious programs in China and Russia is a key motivator. Although hype and secrecy muddy the picture, all three nations appear to have made substantial progress in overcoming key obstacles, such as protecting hypersonic craft from savage frictional heating. Russia recently unveiled a weapon called the Kinzhal, said to reach Mach 10 under its own power, and another that is boosted by a rocket to an astonishing Mach 27. China showed off a rocket-boosted hypersonic glide vehicle (HGV) of its own, the Dongfeng-17, in a recent military parade. The United States, meanwhile, is testing several hypersonic weapons. “It’s a race to the Moon sort of thing,” says Iain Boyd, an aerospace engineer at the University of Colorado, Boulder. “National pride is at stake.”
Despite hype and technological hurdles, a hypersonic arms race is accelerating.
The first launch of Firefly Aerospace’s Alpha rocket has pushed to April 2020 as the company prepares for a very busy year.
SpaceX’s newly redesigned prototype of its Mars-colonizing Starship craft could get off the ground for the first time just two or three months from now, company founder and CEO Elon Musk said.
SpaceX’s New Starship Prototype Could Fly in Just 3 Months, Elon Musk Says :
Using the Moon as a proving ground for living on Mars, this next chapter in exploration will forever establish our presence in the stars.

Elon Musk’s rocket company SpaceX is kicking off the new year with an ultra busy month of tests and missions, including a major test for the company’s first crewed mission to fly NASA astronauts to and back from the International Space Station (ISS).
To drum up hype ahead of the big day, Musk posted a simulated video on Monday showing how the eventual manned launch will look.
