Does NASA have a podcast?
NASA X is a television program and podcast that follows innovative new technologies and the NASA researchers and scientists making it happen.
How does a gravity assist work?
Gravity assists take place when a spacecraft flies past a planet or large moon. This allows the planet's gravity to pull on the spacecraft and change its orbit. Sometimes the spacecraft speeds up, sometimes it slows down - depending on whether it passes behind or in front of the planet.
What is gravity assist NASA?
A gravity assist around a planet changes a spacecraft's velocity (relative to the Sun) by entering and leaving the gravitational sphere of influence of a planet. The spacecraft's speed increases as it approaches the planet and decreases as it leaves the planet.
Does gravity assist slow down the planet?
Depending on the relative direction of motion of the planet and the spacecraft, a gravity assist can either speed up, slow down, or merely change the direction of the spacecraft.
How do you plan a gravity assist?
How to do itGet your ship into a circular Low Kerbin Orbit.Zoom out so you can see the orbit of Kerbin around the sun.Arrange for a fly-by with the Mun just like you learned in the "Going to the Mun" ingame tutorial, but arrange for it to happen while the Mun is heading into the direction you want to go.More items...•
Who invented gravity assist?
The first mission to use a gravity assist was Pioneer 10, which increased its velocity from 52,000 km/h to 132,000 km/h as it passed by Jupiter in December, 1973....Michael Minovitch.Michael A.

Can you get a gravity assist from the Sun?
The answer is no, because the Sun and planets are all moving though the galaxy at the same speed. However, you could do an Oberth maneuver (sometimes called a powered gravity assist) but which is different from gravity assist.
Is space exploration worth the money?
Studying space helps us understand our own world Studying the cosmos gives us an important perspective shift. When we learn about what lies beyond Earth, it gives us context for understanding our own planet. Studying the other worlds of our solar system and beyond makes it clear that Earth is a precious oasis for life.
Where is Voyager 1 now?
Voyager 1 is currently navigating through interstellar space. It passed the border of the solar wind's dominion in space, called the heliopause, back in 2012. However, the spacecraft is still within the Sun's gravitational grasp and hasn't left the Solar System (yet).
What spacecraft used gravity assist?
Some History. Several robotic spacecraft have used the "gravity assist" technique to achieve their targets "high up" in the Sun's gravity well. Voyager 2 launched in August 1977 and flew by Jupiter for reconnaissance, and for a trajectory boost to Saturn.
Can you slingshot around the moon?
But when it gets to the Moon, the Moon is the closest body so its gravity will have the strongest effect on the spacecraft. If it flies past close enough and stays flying fast enough that it can't be captured by the body to start orbiting it, that spacecraft will slingshot around.

Gravity Assist: A New Set of X-Ray Eyes is Launching, with Martin Weisskopf
NASA is about to launch a new spacecraft to look at the universe in X-ray light. The Imaging X-Ray Polarimetry Explorer, IXPE, will look at extreme objects such as black holes, neutron stars, and supernovae, asking fundamental questions about how ...
Gravity Assist: How to Move an Asteroid, with Nancy Chabot
NASA’s Double Asteroid Redirection Test Mission, or DART, will deliberately impact a small asteroid called Dimorphos to deflect its orbit around a bigger object, Didymos. Nancy Chabot, planetary scientist at the Johns Hopkins University Applied Physics Laboratory, has the details.
Gravity Assist: Solar Power for the Moon, with Lyndsey McMillon-Brown
As NASA prepares to send astronauts to the Moon through the Artemis program, engineers are working on technologies that will give these explorers power – solar power, that is. In space, the harsh radiation and huge temperature changes make for ...
Gravity Assist: Meet a Space Weather Scientist, with Yaireska Collado-Vega
Yaireska Collado-Vega leads a team at NASA’s Goddard Spacecraft Center that is studying the solar weather environment so that robots and people exploring space can be protected. In this episode of Gravity Assist, she describes the excitement and challenges of ...
Gravity Assist: Lucy and the Space Fossils, with Hal Levison
To get a more complete understanding of the full history of our solar system, NASA is sending a spacecraft called Lucy to investigate the Trojans, mysterious small objects that share an orbit of the Sun with Jupiter. Principal investigator Hal ...
Gravity Assist: Goodbye Saturn, Hello Earth, with Janelle Wellons
Janelle Wellons likes to say that she operates “fancy space cameras.” At NASA’s Jet Propulsion Laboratory, she creates commands that allow spacecraft to take valuable scientific data in our solar system and here at planet Earth.
Gravity Assist: Freaky Physics on the Space Station, with Ethan Elliott
The laws of physics get very, very weird in the realm of particles too small for the eye to see. Aboard the International Space Station, an experiment called the Cold Atom Laboratory (CAL) is exploring how the universe works .
