We do not appear to have a 'general' space thread, so i am opening this one.

Reports (unconfirmed) that Capstone has arrive in lunar orbit.

So is this thread infinite and is it possible to exceed the speed of light in this thread? ;)))
My necessaries are embark'd: farewell. Adieu! I have too grieved a heart to take a tedious leave.

The CAPSTONE mission operations team confirmed that NASA’s CAPSTONE spacecraft arrived at its orbit at the Moon Sunday evening. The CubeSat completed an initial orbit insertion maneuver, firing its thrusters to put the spacecraft into orbit, at 7:39 p.m. EST.

CAPSTONE is now in a near-rectilinear halo orbit, or NRHO. This particular NRHO is the same orbit that will be used by Gateway, the Moon-orbiting space station that will support NASA’s Artemis missions. CAPSTONE is the first spacecraft to fly an NRHO, and the first CubeSat to operate at the Moon.

In the next five days, CAPSTONE will perform two additional clean-up maneuvers to refine its orbit. After these maneuvers, the team will review data to confirm that CAPSTONE remains on track in the NRHO.

Interactive Map of the Universe

#5 Post by TheGreenAnger » Fri Nov 18, 2022 6:33 pm

A new map of the universe displays for the first time the span of the entire known cosmos with pinpoint accuracy and sweeping beauty.
Created by Johns Hopkins University astronomers with data mined over two decades by the Sloan Digital Sky Survey, the map allows the public to experience data previously only accessible to scientists.

The interactive map, which depicts the actual position and real colors of 200,000 galaxies, is available online, where it can also be downloaded for free.

"Growing up I was very inspired by astronomy pictures, stars, nebulae and galaxies, and now it's our time to create a new type of picture to inspire people," says map creator Brice Ménard, a professor at Johns Hopkins. "Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everybody what the universe really looks like."

The Sloan Digital Sky Survey is a pioneering effort to capture the night sky through a telescope based in New Mexico. Night after night for years, the telescope aimed at slightly different locations to capture this unusually broad perspective.

The map, which Ménard assembled with the help of former Johns Hopkins computer science student Nikita Shtarkman, visualizes a slice of the universe, or about 200,000 galaxies—each dot on the map is a galaxy and each galaxy contains billions of stars and planets. The Milky Way is simply one of these dots, the one at the very bottom of the map.

The expansion of the universe contributes to make this map even more colorful. The farther an object, the redder it appears. The top of the map reveals the first flash of radiation emitted soon after the Big Bang, 13.7 billion years ago.

"In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets," Ménard says. "We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale."
Ménard hopes people will experience both the map's undeniable beauty and its awe-inspiring sweep of scale.

"From this speck at the bottom," he says, "we are able to map out galaxies across the entire universe, and that that says something about the power of science."
