The project made use of measurements from InSight’s first 900 days on Mars—a long enough time frame to see changes on the scale of milliarcseconds per year—and put the lander’s Rotation ...
This system is also much more precise: while the Mars Exploration Rovers could have landed anywhere within their respective 93-mile by 12-mile (150 by 20 kilometer) landing ellipses, Mars Science Laboratory landed within a 12-mile (20-kilometer) ellipse. [7] Mars 2020 has even more precise system, and landing ellipse of 7.7 by 6.6 km. [8]
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 ...
Zubrin writes that faster routes have a significantly higher delta-v cost and free-return duration (e.g. transfer to Mars in 130 days takes 7.93 km/s delta-v and 4 years on the free return), and so he advocates for the 180-day transfer. [8] A free return is also the part of various other mission designs, such as Mars Semi-Direct and Inspiration ...
Buzz Aldrin, Apollo 11 astronaut and the second person to set foot on the moon, may be 87, but he's keeping his mind focused on the next space frontier. For decades now, he's thought about how to ...

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 ...
Getting to Mars is never going to be cheap. But a couple of mathematicians have figured out how to shave some significant bucks off the price tag. Rather than fly to the red planet when its orbit ...
