The InSight Mars lander has turned out to be a gift that keeps on giving. Even though its mission ended late last year, the data sent back to Earth by the lander has continued to provide new and ...
At higher speeds, the time on board will run even slower, so the astronaut could travel to the center of the Milky Way (30,000 light years from Earth) and back in 40 years ship-time. But the speed according to Earth clocks will always be less than 1 light year per Earth year, so, when back home, the astronaut will find that more than 60 ...
At a constant acceleration of 1 g, a rocket could travel the diameter of our galaxy in about 12 years ship time, and about 113,000 years planetary time. If the last half of the trip involves deceleration at 1 g, the trip would take about 24 years. If the trip is merely to the nearest star, with deceleration the last half of the way, it would ...
While it takes light approximately 2.54 million years to traverse the gulf of space between Earth and, for instance, the Andromeda Galaxy, it would take a much shorter amount of time from the point of view of a traveler at close to the speed of light due to the effects of time dilation; the time experienced by the traveler depending both on velocity (anything less than the speed of light) and ...
NASA will test a nuclear-powered rocket for space travel. The technology could speed up a manned trip to Mars from the current seven-month minimum to 45 days.
The company is one of NASA's largest contractors and is one of several currently working on projects related to Mars. So far, only unmanned rovers and orbiters have made it to the Red Planet. When ...
Mars comes closer to Earth more than any other planet save Venus at its nearest—56 million km is the closest distance between Mars and Earth, whereas the closest Venus comes to Earth is 40 million km. Mars comes closest to Earth every other year, around the time of its opposition, when Earth is sweeping between the Sun and Mars. Extra-close ...
NASA's mission to return samples from Mars and potentially discover the first signs of alien life has a new timeline. The samples may arrive sooner. NASA scrapped its $11 billion scheme to grab ...
