There are about 5,000 known species of jumping spiders. Orb webs and cobwebs are excellent at catching flying insects, but the mesophiles are still fine in their burrows, as though insects never evolved flight.
about 20,000 years ago a very large comet came in from deep space and went into orbit around the sun. This would be a comet of the diameter of 100 km, maybe 200. Comes in, gets captured by the sun's gravity, goes into
conditions. So that's the Mustafar like planet from uh from that third Star Wars orbit surrounds a pair of stars rather than a single star. I played a small role in discovering this planet with a a
And because we know how massive the stars are-- we vaguely understand stars-- we can work out that the thing at the center that they're orbiting must weigh a few million times the mass of the Sun-- and that mass must be crammed into a volume of space that would fit within the orbit of Neptune.
There is a nucleus, a middle of the atom, which we now know is full of protons and neutrons, and there are electrons orbiting around the atom, OK? The problem is that, even though this is consistent with certain pieces of data, it can't be true as the final answer, at least,
We do that by getting on the ground, orbit. Orbiters acquire remote data, put all that together. Right now, for instance, we have enough measurements of the weather in specific locations that we have created a global circulation model of Mars.
until 2024, maybe 2028, and then to begin to think in terms of commercial exploitation of the low Earth's orbit. But we have also to think in terms of this expansion and expanding the economical sphere, I would say, for Earth. So that means that's really an interesting concept in order to rethink everything in terms of governance, interfaces, partners that we will be part,
We've been thinking about it since the 1970s, this notion of not only going to Mars and doing in situ science with instruments that are carried on some thing-- orbiter, rover, lander-- but actually bringing samples back, and of wide variety of ways of doing that. I mean, if you defocus your eyes on what you're trying to accomplish, and you just say, listen, I want to get a bag of rocks back from Mars,
still approaching the low point of the orbit and still had to get the Last of The Descent and all of the vertical descent down to that new

these orbits with the innermost stable circular orbit where you could be sort of in Dante's limbo if you were on that orbit you could be there uh for infinity and and the Curious Thing things about uh black Hool there in their vicinity not only is space deformed but the nature of time also changes so time
But before that, we flew flybys of about two kilometers. Orbiting a changing comet environment, and I'll tell a little bit of the story about how the spacecraft saved one time when we flew too closely.
And the treadmill is crazy. Orbital is like a great pickup truck.
Earth Engine in a very, very short form is what happens when you take all of the images that come from the many dozens of scientific spacecraft orbiting the planet run by the US government and other governments, take the data out of these sorts of archives, and put them into this sort of place, which is a Google data center where we put all of the image data co-located
And every time I think about that discovery it just blows my mind that we little creatures here on this one planet orbiting an ordinary star in one galaxy can figure out that our whole universe began at a certain finite time in the past and actually calculate when that was.
orbit around the sun, rather famously.
orbit? Do you think that's sufficient for a national space program or should we press for more manned space exploration, return to more Mars perhaps?
orbit around the Earth that are operated by the national reconnaissance office they're called LaCrosse or Onyx
The orb of recording 360... is 8K at 30 fps, the correct frame rate.
this orb . I felt it, and it was cool.
But that's not true. Because orb webs include that spiral capture silk that I showed you. Most araneomorphs, the majority of araneomorphs, cannot make that capture spiral silk.
The orbits are not perfect circles. He made them perfect circles because it's the universe. God created the universe.
This would be a comet of the diameter of 100 km, maybe 200. Comes in, gets captured by the sun's gravity, goes into an orbit. That orbit crosses the orbit of the earth. While you're dealing with one large object, the chances of getting hit are extremely low. It would be very bad if

aligned with each other. Mathematically, it is perfectly plausible to construct a solar system with highly eccentric elliptical orbits that are tilted at large angles with respect to each other. So the fact that the actual solar system has these symmetries that with circular orbits and aligned orbits seems to be

and orbit the sun and they have to have orbits of more than 200 years.
And Orban, the current prime minister, is blaming the migrants.
An orbital mission would also allow the crew to conduct the photographic reconnaissance that was necessary to look for smooth, safe landing

An unknown landing environment, we'll talk more about that later. And orbiting a low-gravity body. Just to give you an idea of the scale of the Rosetta mission, 26 instruments on both the Lander and Orbiter.

Mars' orbit was so elliptical.
The orbit would be exactly the same.
in orbital period, mass, radius, radiation, energy, all of these parameters.
And Orbital space sciences-- Orbital Sciences is also flying commercial vehicles to ISS, unmanned
The orbital vehicle right now is designed to burn up.
But Newton's law of gravity was a little bit off in explaining the orbit of the planet Mercury. Its orbit shifted by a tiny fraction of a degree every orbit that was not accountable by Newton's law of gravity. And Newton's law of gravity was eventually replaced by Einstein's law of gravity.
Commissioning orbit is where you check out the spacecraft and you check out the science instruments before you commit to doing the science observations.
The orbital dynamics made the trip safer and shorter the earlier you left.
Earth orbit. And they're doing pretty neat stuff.
in orbit by myself while they were down on the surface. Then when they come back into Lunar orbit while they rendezvoused, I docked. Then I got to fly them all the way back home.
Mars orbit and the the red winged craft is is starting its descent for the first landing on Mars notice the big wings

So imagine an orb , a glowing ball of light that can float around.
