NASA Mars InSight Landing: Back to the red planet again

More than six months and 300 million miles since it was launched from California’s Vandenberg Air Force Base, NASA’s InSight Lander will arrive on March on Monday to study the Red Planet.

NASA’s study of Mars has focused on the plan’s surface and the opportunity to live early in its history. On the other hand, the InSight mission – the name of a compression of interior prospecting using seismic surveys, geodesy and heat transport – will study the mysteries of the deep interior of the planet, which aim to answer geophysical questions about its structure, composition and how it was formed. 1

9659003] When landed?

The countdown is expected to occur at 2:54 pm East Time

To be exact, it is “Earth Recipients Time” – when the signal that reports the landing arrives to the ground (and the start of cheering in the control room ).

The actual landing is scheduled to occur at 02:47. The radio signal must then travel 91 million miles to Earth from Mars, arriving approximately 8 minutes later (how much time it takes light to travel so far).

The very thin air of Mars makes the landing particularly challenging. There is enough air that the friction of the molecules will heat parts of the outside of InSight to 2.700 degrees Fahrenheit – hot enough to melt steel – but not enough air to drag to slow the spacecraft a lot.

Thus, the InSight landlord will use a series of mechanisms – a heat shield, parachute and rocket motors – to slow down. It will arrive on the Mars surface at a speed of 5 miles per hour. Sixteen minutes later – to allow time for dust kicked up from landing to settle – spacecraft is to unfurl its solar panels.

NASA engineers know that the system can work. The design of InSight is almost identical to that of the Phoenix Mars Lander which successfully sits down on March 2008.

Where on Mars is InSight landing?

The landing site has the idyllic name Elysium Planitia, near the equator of the northern hemisphere. Mission scientists have described the region similar to a parking lot or “Kansas without the corn.”

It is intentional. Because the mission is not interested in rocky terrain or beautiful sunsets, planners chose the flatest and safest place spacecraft could land.

What do scientists hope to learn?

How often does the field shake with marches? How big is the melted core of Mars? How thick is the crust? How much heat flows from decay of radioactive substances in the planet’s core? There are some questions that mission researchers hope to answer.

InSight has two main instruments: a dome-shaped package containing seismometers and a heat profile that will dig about 16 meters down. NASA has spent $ 814 million on InSight. In addition, France and Germany invested $ 180 million to build these main instruments.

The seismometers, which are intended to measure surface movements less than the width of a hydrogen atom, will produce what is essentially sonogram of the inside of the planet. In particular, researchers want to register at least 10-12 Marchquakes over two years. Temblors on Mars are not caused by plattektonics, as on earth. Instead, they are generated when the crust of the earth bursts because of its internal cooling and shrinkage. Seismometers can also detect other seismic vibrations from meteors attacking Mars.

With the information, researchers expect that they can merge a three-dimensional image of the planet’s interior.

When does the main science go Part of the mission starts?

Not a while.

The first five to six weeks will largely be used to control the spacecraft’s health, including its robot arm. After that, the arm will lift the seismometer dome from the landlord’s main deck and place it on the ground. The fertilizer probe is set after it and takes about 40 days to reach its final depth of 16 feet.

InSight’s primary mission on the surface should be almost two years.

What are the two portfolios flying by Mars on Monday?

It’s not portfolios. They are small spacecraft!

NASA uses the InSight mission to test new technology. Two identical spacecraft known as Mars Cube One, or MarCO for cards, launched with InSight in May. MarCO A and B are then separated from InSight’s cruise stage and have been behind it for a long time.

Hundreds of miniature satellites, known as CubeSats, have launched circuits around the world in recent years, but this is the first time CubeSats has been sent on an interplanetary journey.

MarCO Spacecraft will relay InSight telemetry to Earth. If it works, an InSight photo may arrive within minutes of arrival. But NASA is not dependent on MarCO. The data will also be forwarded through two other circuits, Mars Odyssey and Mars Reconnaissance Orbiter.

What other spacecraft are on and around Mars?

In circulation, NASA also has Mars Reconnaissance Orbiter, Mars Odyssey and Maven. The European Space Agency has Mars Express and ExoMars Trace Gas Orbiter. The Indian Space Research Organization has Mars Orbiter Mission, also known as Mangalyaan.

On the surface, NASA now has the curiosity and potential of robbers, although the solar power opportunity has been quiet since the summer when a global dust storm prevented it from generating enough power to work. NASA hopes that the opportunity will revive now the clouds have cleared.

What assignments to Mars are planned for the future?

The year 2020 may be busy.

NASA plans to launch another rover, similar to curiosity, but with another set of instruments looking for building blocks in life. A cooperation between the European Space Agency and Russia will launch ExoMars, which will also contain instruments to try to answer whether life ever existed on Mars.

China, Japan, the United Arab Emirates and India also intend to launch spacecraft for March 2020.
