SpaceX aiming for first commercial spacewalk this year

A billionaire entrepreneur who spent several days in orbit last year as part of SpaceX’s first civilian-only crew is planning additional missions that will include the first commercial spacewalk.

Jared Isaacman, founder and CEO of Shift4 Payments, said this week he hopes the privately funded space program, called Polaris, will help to rapidly advance human spaceflight programs while at the same time raising funds for causes on Earth.

Polaris will consist of three missions. The first, Polaris Dawn, will, like Isaacman’s recent Inspiration4 mission, utilize thoroughly tested SpaceX hardware, specifically a Falcon 9 launch vehicle and a Crew Dragon spacecraft.

Comprising four crewmembers, including Isaacman, the five-day Polaris Dawn mission is targeted for later this year and will fly higher than any previous Crew Dragon as it aims for the highest crewed Earth orbit ever flown, a record currently held by NASA’s Gemini 11 mission of 1966 when the spacecraft reached an Earth orbit of 854 miles (1,374 km).

The mission will also attempt the first commercial spacewalk, in other words, one that is not funded by NASA or any other government-sponsored space agency.

The crew will also become the first to conduct tests on SpaceX’s recently deployed laser-based Starlink satellites, which could provide vital communication links for NASA’s upcoming crewed missions to the moon and beyond.

Scientific research will also be carried out during the Polaris Dawn mission.

Flying to space alongside Isaacman will be three other amateur astronauts: Scott Poteet, a retired U.S. Air Force fighter pilot; Sarah Gillis, a lead space operations engineer at SpaceX, responsible for overseeing the company’s astronaut training program; and Anna Menon, also a lead space operations engineer at SpaceX.

Whether Polaris Dawn can launch this year depends on SpaceX overcoming challenges that include the creation of its own spacesuit for the planned spacewalk.

While the Polaris Program’s second mission will also use a Crew Dragon, the third will take a giant leap by becoming the first crewed mission on SpaceX’s next-generation Starship vehicle.

Isaacman hasn’t attached a date to the first crewed Starship mission, understandable considering SpaceX has yet to send the rocket-and-spacecraft combo on its first orbital test flight, a highly anticipated event that could happen next month.

Isaacman’s grand Polaris plan takes SpaceX from a spaceflight provider to a space program organizer, a first for a commercial spaceflight company, and further evidence of the rapidly changing landscape as private firms endeavor to open up space to more people beyond trained astronauts and space programs funded by government money.

Lightsails have hit another speed bump on the road to interstellar travel
The coolest interstellar travel idea may get betrayed by the light pushing it
LightSail in Earth orbit

Laser-powered lightsails are one of the coolest answers to spaceflight. It might not be as sci-fi-sounding as a warp drive, but now, its practicality has also come under question. Using lightsails, a spacecraft could unfurl an ultra-thin reflective sail and let a powerful laser push it toward another star, without relying on fuel.

The tech was simple and elegant--except it's also more complicated than it sounds. A new preprint from researchers Chao Shen and Jiaze Li of the Harbin Institute of Technology suggests that relativistic lightsails may run into a hidden propulsion problem once they start moving extremely fast.

The galaxy has an exoplanet size mystery, and NASA’s EVE mission wants to solve it
This planet-hunting mission wants to catch baby worlds before they grow up

Mankind venturing into space ended up creating more questions than it answered, and one of the dilemmas is related to the planet sizes. Astronomers have found plenty of rocky super-Earths and plenty of puffier sub-Neptunes, but far fewer planets with a radius of about 1.8 times Earth’s.

That gap is known as the radius valley, and a proposed mission called the Early eVolution Explorer, or EVE, wants to figure out why it exists. NASA has a simple plan: look at planets while they are still young. The mission concept, detailed in a new arXiv preprint and covered by Phys.org, would focus on newly formed star clusters to see what small planets look like before billions of years of evolution.

We just got a hot signal that a Tesla and SpaceX merger could happen, after all
Tesla

For years, the idea of Tesla and SpaceX becoming a single company has lived somewhere between ambitious business theory and Elon Musk fan fiction. The two companies already share DNA, leadership influence, engineering talent, and long-term goals. But every time the topic surfaced, it felt more like an interesting thought experiment than a realistic possibility. Now, one of the most important people at SpaceX has added fresh fuel to the conversation.

Speaking in a recent CNBC interview, SpaceX President and COO Gwynne Shotwell was asked about the possibility of closer ties between Tesla and SpaceX. Her response wasn’t a flat-out denial. In fact, she suggested that bringing the two companies together could make life a little easier for Musk. That may sound like an offhand comment, but coming from Shotwell, it’s noteworthy. She’s been at SpaceX since its earliest days and remains one of the company's most influential executives.
