Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light; a little too much pseudoscience and not enough science. We'll let other publications offer you a daily horoscope. At Ars Technica, we're going to take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder.

Good morning. It is November 3, and today we have a treat from NASA. A couple of days ago I wrote about NASA's Lucy mission preparing to fly by its first asteroid target, the small main-belt asteroid Dinkinesh. Now, it is complete.

This flyby was not so much about the science but rather proving the capability of the spacecraft to point its instruments and take data while whizzing by an asteroid. In this case, Lucy zoomed by Dinkinesh at a speed of 10,000 mph (4,470 meters per second). And, as can be seen from the first images returned by Lucy, the spacecraft succeeded.

Until recently, OLED computer monitor selection was limited. Today, there's more than a handful available. LG Display and Samsung Display have made picking an OLED monitor exciting by designing competing models—white OLED (WOLED) and quantum dot OLED (QD-OLED), respectively—and monitor vendors are steadily addressing OLED scarcity and price barriers.

But what about longstanding fears of OLED burn-in?

People tend to display static images on computer monitors more frequently than on TVs—things like icons, taskbars, and browser address bars—making burn-in risk a concern.

Welcome to Edition 6.18 of the Rocket Report! In this newsletter we have a double dose of news from China, where there are two separate efforts to duplicate SpaceX's Falcon 9 rocket. On the American side of the pond we also have two stories about United Launch Alliance and its effort to get Vulcan flying, and the cost of the rocket's delays.

As always, we welcome reader submissions, and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Chinese company tests vertical landing. A Chinese commercial rocket company has successfully launched and safely landed a test article on its path to developing a reusable launch vehicle, Space News reports. Beijing-based Interstellar Glory Space Technology Ltd., also known as iSpace, launched the Hyperbola-2Y single-stage hopper on Thursday. The methane-liquid oxygen reusable test vehicle rose to a height of 178 meters during its 51-second flight.
