After landing on the probe Mars (everything is going well – and sometimes not going to), it will use a robot arm to place a robot's arm in a "mole" to carve it five meters below the surface and leave a long sensor-loaded tail inside it. wake up. There, he will measure the vital signs of Mars: to determine how much heat is flowing from the planet's core into the surface.
These data will bring new insights into the anatomy of our nearest neighbors and will even indicate how the solar system is formed.
Fittock, 34, received two diplomas in astrophysics and mechanical engineering at the University of Monash in 2001 in his left school. Unusual but deliberate combination: he wanted to work on space technologist.
And seven years ago, he found himself in DLR through "good luck or a good opportunity," he says, "mole development test leader."
In a 25-minute team, ecek Susanna una, who served as chief engineer for the surface part, will distribute the mole, preserve its safety, guide its journey, and transmit its readings to the Earth.
. Excuse me, but we had to break a new ground, F says Fittock.
There was a lot of trouble to get mole around Mars to work reliably.
Or We just don't know what we're getting there, bil he says. It's not like they can go and look.
Iniz We can make predictions from what we can see in the orbit, but when you go a little underneath the surface, we should make wider and broader predictions.
”We're going where no one's gone,“ he said.
The first challenge of his team was that the mole descended deep enough to get good data.
One kilogram, 30 cm long, shakes and shakes it through sand and rocks and fills it back.
They created a zayıf very long, long sandbox u to test how this would happen.
Zor Short summary is really hard, F says Fittock.
Çarp It took longer to take longer than expected and during this time he was hurting himself, because he was hitting and throwing. It was a great technical challenge, how to make it stronger. Büyük
They expect the gravity of Mars to give them a hand and that the sand is looser than the equivalent of Earth.
But they are also waiting to hit the rocks.
Or They chose a nice landing point for us, one should be able to dig and the rocks on the surface can be avoided, “he says.
However, there will be a bir nail moment bir, they say when they first come to the surface, they can be sure they have something to crack.
Even if they contain the mole in the sand, it is likely to have rocks below the surface. Some of them can break apart, navigate others, but some can only prevent them from reaching the desired depth of 5 m.
The process of cavitation, which will begin next year, will be slow and laborious. Each time the mole encounters a problem, it allows the team to analyze the situation and examine its strategy.
Another problem beyond the control of Fittock's team is the landing.
We're going out for a dinner with space engineers.
. I'll be there with my phone, I'm nervous about what's going to be there, as I try to appear as a professional while sitting there. But it's a great dinner, so I think everyone's gonna want to see it. "
Aside from the risks, Fittock says he is sure he has “good science” from his systems.
Geç We'll get a better picture of what Mars is doing now, as well as how Mars came about, how Mars went through the beginning of the solar system, and even better our entire solar system.
”Sometimes we underestimate how little we know about everything outside of the world, and even things on Earth.“
Recently, OHB, a new company in Bremen, took its place as project leader in future space research missions.
He's on a mission working with NASA to go to an asteroid pair named Hera and crash a spacecraft into one of them.
We'll give them useful ideas about how to see a cül World Killer cül asteroid coming towards Earth, and how we can give up their deadly cause.
Ik In the last few years, we've learned that asteroids and comets are different from what we've come to expect from a number of basic ways, F says Fittock.
“We want to know what happens when this effect occurs.“
