NASA will launch a mission to crash into an asteroid (on purpose) overnight tonight and you can watch it lift off live online.

The agency’s Double Asteroid Redirection Test (DART) mission will travel millions of miles out into the solar stem to smash into an asteroid, altering its orbit around a larger space rock to practice in the event of a rogue Earth-bound asteroid. The mission is set to lift off from Space Launch Complex-4 at Vandenberg Space Force Base in California early Wednesday, Nov. 24, at 1:20 a.m. EST (10:20 p.m. PST on Nov. 23/0620 GMT).

O,.o! Circa 2018

We can produce very little antimatter and what we make is very difficult to store. These have been huge obstacles that have made antimatter propulsion many trillions of times beyond technological capabilities.

Positron Dynamics and Ryan Weed get around these issues by using isotopes of Krypton or sodium which naturally produce positrons (anti-electrons). They can use tiny amounts of Krypton isotopes to generation 100 billion to many trillions of positrons. They can also breed more of Krypton 79 isotopes by exposing Krypton 78 to neutrons.

Using a NASA NIAC study they have worked out more details and produced renderings of what the systems will look like.

Tesla has posted new jobs for its Tesla Bot team on its Careers page. Most of the Tesla Bot jobs are located in California except one located in Austin, Texas.

A few of the openings have been posted for quite some time. Tesla has been steadily posting jobs for the Tesla Bot team since the project was announced during Artificial Intelligence or AI Day back in August. Most of the new jobs seem to be related to software development for the Tesla Bot, hinting at the company’s progress with the humanoid robot.

The new Tesla Bot jobs are listed below with their responsibilities.

“These discoveries are essential for mankind to progress into the space age,” said lead research author Professor Sayaka Wakayama, a scientist at Japan’s University of Yamanashi.

There’s no need to discover life on Mars — not when we could possibly make our own.

Scientists have discovered that sperm can potentially survive on Mars for hundreds of years, meaning that humans could possibly reproduce on the Red Planet in the future.

“These discoveries are essential for mankind to progress into the space age,” lead research author Professor Sayaka Wakayama, a scientist at Japan’s University of Yamanashi, told the Daily Mail of the study.

Twitter’s e-commerce initiatives now include livestream shopping and Walmart will be the first retailer to test the new platform. Over the past year, Walmart has invested in live shopping by hosting events across social platforms like TikTok and YouTube, and soon it will debut Twitter’s first-ever shoppable livestream. On November 28, Walmart will kick off a Cyber Deals live event on Twitter, where users will be able to watch a live broadcast, shop the featured products and join the conversation around the event by posting tweets.

The livestream will begin at 7 PM ET on November 28, 2021, and will allow Walmart customers to shop from Twitter as well as a number of other platforms, including Walmart.com/live, and the retailer’s Facebook, Instagram, TikTok and YouTube accounts. Musician-turned-creator Jason Derulo will host the livestream, where he’ll introduce the audience to deals in electronics, home goods, apparel, seasonal décor and more during a 30-minute variety show. Surprise special guests will also drop in, says Walmart.

If we knew that a near-Earth asteroid (NEA) was headed for Earth could we deflect it?

Seeking to find out is the Double Asteroid Redirection Test (DART), a mission from NASA and the European Space Agency (ESA) to smash a 500kg spacecraft into binary asteroid 65,803 Didymos and its moonlet Dimorphos (also called, rather cutely, “Didymoon.”)

The idea is that by creating a “kinetic deflection” on Dimorphos it will ever so slightly change the trajectory of both objects.
