What did MESSENGER find out about Mercury?
What did MESSENGER find out about Mercury?
What was MESSENGER? NASA’s MESSENGER spacecraft orbited Mercury for more than four years. Among its accomplishments, the mission determined Mercury’s surface composition, revealed its geological history, discovered details about its internal magnetic field, and verified its polar deposits are dominantly water-ice.
Is MESSENGER still orbiting Mercury?
MESSENGER entered orbit around Mercury on March 18, 2011, becoming the first spacecraft to do so. It successfully completed its primary mission in 2012….MESSENGER.

Has NASA sent anything to Mercury?
Only one NASA spacecraft has visited Mercury and that was Mariner 10 in 1974 and 1975. It was programmed to fly by the planet three times to take images of its heavily-cratered surface. There’s still more than half of Mercury we’ve never seen before.
When did MESSENGER reach Mercury?
March 18, 2011
On March 18, 2011, MESSENGER fired its main engine and entered a near-polar eccentric orbit around Mercury, with the low point reaching as near to the surface as 124 miles and the high point as far as 9,420 miles, completing each orbit in about 12 hours.
How long does a Mercury year last?
88 days
Mercury/Orbital period
A single year lasts only 88 days on Mercury, but thanks again to its slow rotation, a day lasts twice as long! That means that if you could stand on the surface of Mercury, it would take a staggering 176 Earth days for the Sun to rise, set and rise again to the same place in the sky just once!
How long does it take to get to Mercury?
The fastest spacecraft ever launched from Earth is NASA’s New Horizons mission, currently on its way to visit Pluto and the outer Solar System. New Horizons is traveling at about 80,000 kilometers per hour. It would take about 40 days to get from the Earth to Mercury when they’re closest.
Can a human go to Mercury?
No, Mercury has been visited by spacecraft from Earth, but no human has ever gone into orbit around Mercury, let alone stepped on the surface. However, the temperatures on Mercury are much greater. During the daytime, the surface of Mercury at the equator rises to 700 Kelvin (427 degrees C).
Can humans go to Mercury?
How much is a day in Mercury?
A planet’s day is the time it takes the planet to rotate or spin once on its axis. Mercury rotates very slowly compared to Earth so a day on Mercury is much longer than a day on Earth. A day on Mercury is 58.646 Earth days or 1407.5 hours long while a day on Earth is 23.934 hours long.

What was the mass of the MESSENGER spacecraft?
What was MESSENGER? Nation United States of America (USA) Objective (s) Mercury Orbit Spacecraft MESSENGER Spacecraft Mass 2,443 pounds (1,107.9 kilograms) Mission Design and Management NASA / APL
When is messenger going to be in Mercury orbit?
The spacecraft is designed to rotate the panels away from the Sun to avoid overheating. Wisely, MESSENGER is built with a redundant system so if any one system fails, another can take over. The spacecraft is scheduled to enter Mercury orbit in March 2011.
How does the sunshade on the MESSENGER spacecraft work?
NASA: The sunshade keeps the instruments at room temperature, and you have a protective, multi-layer insulation around the spacecraft. DavidM: Since 1999 NASA has required spacecraft to report their status during critical operations like MOI. What data is Messenger going to transmit during MOI through a low-gain antenna?
