NASA's Super-Sized Space Launch System Might Be Doomed

NASA's Super-Sized Space Launch System Might Be Doomed

But one thing was certain: on Orion’s first foray beyond Earth, a crew-less capsule would complete a six-day circuit of the moon; that’s the mission Bridenstine now says could launch atop a commercial rocket.

But yesterday, China’s space agency announced that the frigidity of the lunar night is even more intense than we’d thought: The country’s Chang’e 4 spacecraft recorded an icy low of –310 degrees Fahrenheit (–190 degrees Celsius).

To pursue the idea, Sitnikov founded StartRocket, which plans to use a hundreds-strong constellation of CubeSats, each equipped with a reflective sail, to display ads, and perhaps emergency and event-based messages.

What Is the Dark Side of the Moon?

(In the case of our moon, astronomers think it once whirled faster about its axis.) But over time, gravity from our planet exerted torque on bulges in the lunar surface, forcing its rotation into synchronization with its orbital period.

Astroscale's first mission, called ELSA-d a cheery acronym that hides the ominous "End-of-Life Service" hidden within it, aims to show that a reaper-style space robot can find lost debris, match a dead satellite’s tumble, and dock.PushersTraditionally, satellites have thrusters that push them to the orbits they need, keep them there, and then (assuming the gas gauge doesn't read "empty") send them shooting down to Earth when the time comes.

OSIRIS-REx will soon enter orbit around the asteroid, where it will spend nearly a year carefully mapping its surface before descending to latch on and collect a sample to bring back to Earth.

“I am still very concerned.” He later cited another launch of 31 objects, of which only 18 had been identified three and a half days in.“We put our plan in front of all the regulators and in front of the Combined Space Operations Center,” Blake says, referring to the relevant part of the Air Force.

Watch SpaceX Attempt Its Wickedly Complex Satellite Launch

The California-based aerospace company is flexing its ridesharing muscles in a carefully choreographed orbital ballet as its flagship rocket—the Falcon 9—prepares to launch 64 small satellites into orbit.The mission, dubbed SSO-A, is slated to lift off a little after 10:30 am PT from the company’s west coast launch site, the second flight within a few weeks for SpaceX.

And all this creation maybe have been the result of an accidental collision: Scientists believe a galaxy in the vicinity collided with ESO 338-4, and their subsequent interaction of gas and dust is what’s feeding all the stellar activity in this region.We’ve come across the galaxy cluster called Abell 2597 in our travels before, but never looking like this.

Astronomers Creep Up to the Edge of the Milky Way’s Black Hole

Astronomers Creep Up to the Edge of the Milky Way’s Black Hole

The idea, first proposed in 2005 by Avery Broderick, now at the Perimeter Institute of Theoretical Physics and the University of Waterloo in Canada, and Avi Loeb of Harvard University, would explain why the black hole appears to flare.“It seems like they’ve got something really exciting here,” added astronomer Andrea Ghez, a longtime competitor to the European team at the University of California, Los Angeles.If these rotating flares are due to hot spots in the way that Broderick and Loeb imagined, additional flares will help reveal the black hole’s “spin,” a measure of its rotation.
