Part of the reason we've gone so long without seeing a SpaceX landing is that the company has been trying to get rid of its excess Block 4 rockets by refusing to land them back on Earth. "The pre-launch agreements Telesat has secured with Hughes and Bell Canada, combined with strong interest from other leading satellite service providers across the Americas and Atlantic, confirm that Telstar 19 VANTAGE delivers superior performance and value for today's bandwidth intensive applications", ...
The Armstrongs turned to Sarasota, Florida-based Collectibles Authentication Guaranty for help with preserving and authenticating the artifacts and memorabilia and chose Heritage Auctions for the sales. "Space is one of the very, very few categories that every single person seems to be interested in", Rohan said in a statement. Four days and 386 242,56km later, at 4.18pm EDT on 20 July, the Apollo 11 craft touched down on the southwestern edge of the Sea of Tranquility.
During that test, the spacecraft's emergency motor was sacked 45 seconds into the flight, at an altitude of 16,000 feet (4,876 meters), slamming the rocket booster with 70,000 pounds of thrust and forceful exhaust. Executives at the company, which was started by Bezos in 2000, said the company planned to launch test flights beginning next year, Reuters reported.
The team is calling one of the new moons an " oddball " because of its unusual orbit. The real oddity of this discovery is the twelfth new moon, which has been described as a real " oddball " for a number of reasons. It has a prograde orbit at a distance where the rest of Jupiter's moons have retrograde orbits. With 67 other known moons flying around Jupiter, there's already a good amount of traffic around the gas planet, as shown in the illustration above.
And the company appeared to nail the test. Once the booster separated, the capsule's escape motor fired, lifting the spacecraft to an altitude of 389,846 feet. (Blue Origin via You Tube) New Shepard's capsule fires its retros as it touches down for a landing. The company's Florida team was watching today's webcast, as was the team at Blue Origin's headquarters in Kent, Wash., where New Shepard hardware is manufactured.
Astronomer Scott Sheppard of the Carnegie Institution for Science is on the hunt for Planet Nine , a hypothetical planet many astronomers think should exist in the distant reaches of our Solar System, beyond Pluto . Most of the moons are the size of large asteroids, measuring between one and three kilometers (about two-thirds of a mile to two miles) in diameter.
