The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). During that journey, engineers have several opportunities to adjust the spacecraft’s flight path, to make sure its speed and direction are best for arrival at Jezero Crater on Mars.
Three days was simply how long it took to get from the TLI engine burn to the CSM engine braking burn via the unpowered cruise. They left on a ‘free return’ trajectory – so, if the SPS engine failed at the moon, the lunar gravity would loop them back toward Earth.
As a result NASA’s official policy forbids pregnancy in space. Female astronauts are tested regularly in the 10 days prior to launch. And sex in space is very much frowned upon.

Long-term exposure causes multiple health problems, one of the most significant being loss of bone and muscle mass. Over time these deconditioning effects can impair astronauts’ performance, increase their risk of injury, reduce their aerobic capacity, and slow down their cardiovascular system.
Besides the 12 people who have walked on the Moon, 12 more have flown to within 0.001 lunar distance of its surface. During each of the six missions with successful lunar landings, one astronaut remained in lunar orbit while the other two landed.
The $720 million New Horizons mission launched in January 2006, speeding away from Earth at a record-breaking 36,400 mph (58,580 km/h). Even at that blistering pace, it still took the probe 9.5 years to reach Pluto, which was about 3 billion miles (5 billion km) from Earth on the day of the flyby.
Blue Origin is a private spaceflight company based in Kent, Washington that is working to send tourists to space on its reusable suborbital rocket called New Shepard.
A rocket ship, on its way to the moon, can get up to almost 25,000 miles per hour in order to escape the Earth’s atmosphere.
NASA this week revealed details about its forthcoming Artemis missions to the Moon. NASA yesterday revealed that its forthcoming Artemis missions to the Moon—including crewed landings on the lunar surface—will cost around $28 billion.
Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).
The pay grades for civilian astronauts are GS-11 through GS-14, based on academic achievements and experience. Currently, a GS-11 astronaut starts at $64,724 per year; a GS-14 astronaut can earn up to $141,715 in annual salary [source: NASA].
there are no hours in space. an hour is a not too convenient unit that is 1/24th of one revolution by the earth on its axis of rotation. Earth gravity is not that strong so it should only dilate time by a little bit.
1d 0h 37m

The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space in one second, and is equal to exactly 299,792,458 metres (983,571,056 ft).
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
But in 1970 future Apollo missions were cancelled. Apollo 17 became the last manned mission to the Moon, for an indefinite amount of time. The main reason for this was money. The cost of getting to the Moon was, ironically, astronomical.
No. Outside mythology, no human has ever attempted to travel to the Sun. The main reason is fairly obvious—it’s too hot. Even in a well-protected spacecraft, you could only get within about 2 million kilometres (1,300,000 mi) before burning up.
There have been journeys to the inner planets: the Messenger, Magellan and Mariner spacecraft to Mercury and Venus. There have, too, been expeditions to Jupiter and Saturn and their colorful flocks of moons. Asteroids and comets and the sun itself have also been studied up close. Many of the missions are ongoing.
Mankind has been studying Jupiter for more than 400 years. … Nine spacecraft have visited Jupiter since 1973, and they’ve discovered a lot about the planet.
