I cannot believe how a “journalist” could write about a live stream from Mars without knowledge of the time delay. Seems like they would have a technical proofreader. Just, ignorant!

The police pull you over and ask you to put your bra back on.

Journalists are so stupid. A laser beam still is limited to c.

They’re trying to reach us about our car’s extended warranty ...

... if you're in your car moving at the speed of light...

You can't get to the speed of light. Your mass increases as you move faster and faster. Your kinetic energy increases and is added to your mass. This eventually requires an infinite amount of energy to push you to the speed of light.

“Nudge me when NASA manages laser propulsion like the Moties used in Niven and Pournelle’s The Mote in God’s Eye. Excellent first contact science fiction by two of the best.”

This is a great story I’ve reread it several times looks like I will again “Crazy Eddie” lol

So yesterday ... electric propulsion is in, as is the inertia-less drive.

may open the door to a future where humans on Mars send back livestreams in real time....

What? They're claiming communications at faster than the speed of light? Call me skeptical.

How can they have instant communications?

It wasn't instantaneous. It merely worked.

The laser projects a tight beam that doesn't disperse as much as a radio transmission. The beam arrives at the destination with enough energy to be detected. The reply can also be received.

To do this with radio requires the use of mammoth dish antennas. The lasers make communications possible without large infrastructure.

Poor writing in the article. I think the “higher speed” really means greater bandwidth/data rate.

As pointed out by a Freeper yesterday, there are two kinds of people: Those who use the metric system, and those who landed on the moon.

Dont laser beams travel at the same speed as radio waves? How can they have instant communications?

Less divergence is one reason. The laser beam spreads out much slower than that of a directional radio signal.

The blogger needs to look up the definition of deep space.

And by large, we’re talking now-defunct Arecibo radio-telescope large.

So NASA shot a shark with a laser into space to test this out. Sounds like something Dr. Evil would do.

Look at a clock, then take off at the speed of light. The time on the clock will remain constant, since the light reflecting off of it is traveling at the same speed you are.
