Jupiter, like other planets, sometimes appears to move backward in the sky due to apparent retrograde motion. This is an optical illusion caused by Earth’s faster orbit overtaking the slower orbit of Jupiter. As Earth passes Jupiter, it looks like Jupiter is moving backward for a period of time before resuming its normal eastward movement. #space #jupiter #planet #retrograde #earth

What’s your reaction to this wild NASA test flight? Neil Armstrong: Simulator Crash Almost Killed Apollo 11 Astronaut Year Before Lunar Landing Fourteen months before taking that celebrated first step on the moon, astronaut Neil Armstrong took a ride in a bizarre test vehicle at a training facility in Houston—and narrowly escaped death when it veered out of control and crashed. It was May 6, 1968. Armstrong was strapped into what was called the Lunar Landing Research Vehicle (later versions were called the Lunar Landing Training Vehicle), an ungainly rocket- and jet-powered craft designed as a simulator for the lunar module that would take astronauts to the surface of the moon. Armstrong was about 30 feet above the ground when the LLRV’s rockets failed. The craft lurched violently and began to lose altitude. Armstrong struggled to regain control before deciding it was a lost cause. He ejected from the LLRV moments before it crashed and exploded, as can be seen in this video. Despite the incident, Armstrong praised the craft humorously dubbed the “flying bedstead,” saying it did “an excellent job of factually capturing the handling characteristics of the lunar module in the landing maneuver.” In fact, the simulator that nearly cost Armstrong his life may have saved his life and that of fellow Apollo 11 astronaut Buzz Aldrin the day they touched down on the moon. #space #fail #testflight #nasa #rocket

Artemis Solid Rocket Booster made by Northrop Grumman - named the Booster Obsolescence and Life Extension (BOLE), suffered an anomaly during its test firing at the Promontory test site in Utah. During the final part of the two minute firing, the booster’s nozzle suffered a major failure, liberating entirely from the motor. #space #rocket #rocketengine #fail #nasa

Neutron stars are incredibly dense objects. Their typical density ranges from 3.7 x 10^17 to 5.9 x 10^17 kilograms per cubic meter. This is equivalent to about 2.6 x 10^14 to 4.1 x 10^14 times the density of the sun. In simpler terms, a teaspoon of neutron star material would weigh around a billion tons. #space #earth #neutronstar #dense #density #star

Why does Saturn appear so big? It doesn’t — what is pictured are foreground clouds on Earth crossing in front of the Moon. The Moon shows a slight crescent phase with most of its surface visible by reflected Earthlight, known as Da Vinci glow. The Sun directly illuminates the brightly lit lunar crescent from the bottom, which means that the Sun must be below the horizon and so the image was taken before sunrise. This double take-inducing picture was captured on 2019 December 24, two days before the Moon slid in front of the Sun to create a solar eclipse. #moon #beautiful #space #saturn #rings
