NASA's MAVEN is declining in Mars 2020 Rover



NASA's 4-year atmosphere – whispering Mars
Atmospheric and volatile evolution (MAVEN) mission launches a new one
campaign to tighten orbit around Mars. The operation will reduce
the largest MAVEN spacecraft elliptical orbit point from 3850 to 2800
miles (6,200-4,500 kilometers) above the surface and ready to receive it
additional responsibility as a data relay NASA 2020
The MAVEN spacecraft made a great impression
work by teaching us how Mars lost its atmosphere and provided other important things
scientific insights on Mars climate development, ”said Jim
Watzin, Director of NASA's Mars Research Program. "Now we are recruiting
this would help NASA to communicate with the future Mars rover and his heirs.

Although MAVEN's new orbit will not be drastic
shorter than its current orbit, even this small change will be much larger
improve your communication capabilities. "It's like using a mobile phone,"
said Bruce Jakosky MAVEN major investigator at the University of Colorado, Boulder. "
closer to you is the cell tower, the stronger the signal. "

is not the only rigorous benefit of orbit. Approximately 1

000 miles arrive
1,500 kilometers) will also allow the MAVEN orbit to have more Mars
often – 6.8 orbit on Earth Day versus 5.3. before, and yes
to communicate more often with Mars rovers. Until you use the relay
MAVEN will continue to analyze the structure and composition
Mars atmosphere. “We are planning an energetic scientific mission
far into the future, ”said Jakosky.

The MAVEN mission was created for two years
space, but the spacecraft is still operating normally. With a mission
NASA plans to use the MAVEN relay
as long as possible. The MAVEN orbiter has a very high frequency
The radio transceiver is similar to other Mars orbits
allows it to transfer data between Earth and rolling stock or landing on Mars. MAVEN
The spacecraft has sometimes served as a NASA communication link with

Over the next few months MAVEN engineers
use a navigation technique called aerobics, eg using brakes a
Car – Take advantage of the Red Planet's top atmosphere stretching

would feel if you put your hand out of a moving car window

According to the observation of the spacecraft, the navigation team
NASA's Jet Propulsion Laboratory in Pasadena, California and Lockheed
Martin in Littleton, Colorado, engineers will start dropping down carefully
the lowest part of the orbit of the spacecraft in the upper atmosphere of Mars
in the next couple of days shooting your engines. Spacecraft will create
Mars down at around 360 times in the next 2.5 months slows down
Lower it slightly in every atmosphere. Although it may look like
a time-consuming process, aerobics is the most effective way to change
The trajectory of the spacecraft, said Jakosky: "This effect is the same as we do
we fired our engines a little on each orbit, but in this way we use a lot
little fuel.

Fortunately, the team has a lot of work experience
spacecraft at these lower heights. On the nine previous occasions
mission, MAVEN engineers inserted the orbit into the same altitude goals
aerobics to measure the atmosphere of Mars. As a result
these "deep dips" and other measurements, NASA learned that the sun
The wind and radiation took away most of Mars's atmosphere and changed the planet
The early climate is warm and humid to the dry environment we see today. MAVEN also
Mars discovered two new types of Auroras and the presence of charged metal atoms in its upper atmosphere, saying that many rubbish hits Mars, which can affect

MAVEN's principal researcher is at Vilnius University
Colorado Atmosphere and Space Physics Laboratory, Boulder. The
the university has provided two scientific instruments and directs research activities
education and public awareness missions. NASA's Goddard Space
Greenbelt, Maryland, operates a MAVEN project and provides
two scientific instruments for the mission. Lockheed Martin built a spaceship
and is responsible for mission operations. University of California
The Berkeley Space Science Laboratory has also provided four scientific tools
