NASA Lunar Lander Thrusters hold up to Over 60 Hot-Fire Tests

 

NASA - National Aeronautics and Space AdministrationHuntsville, AL – Future NASA Artemis lunar landers could use next-generation thrusters, the small rocket engines used to make alterations in a spacecraft’s flight path or altitude, to enter lunar orbit and descend to the surface. Before the engines make the trip to the Moon, helping deliver new science instruments and technology demonstrations, they’re being tested here on Earth.

NASA and Frontier Aerospace of Simi Valley, California, performed roughly 60 hot-fire tests on two thruster prototypes over the course of 10 days.

NASA is looking for ways to Target an Asteroid

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Like many of his colleagues at NASA’s Jet Propulsion Laboratory, Pasadena, CA, Shyam Bhaskaran is working a lot with asteroids these days. And also like many of his colleagues, the deep space navigator devotes a great deal of time to crafting, and contemplating, computer-generated 3-D models of these intriguing nomads of the solar system.

But while many of his coworkers are calculating asteroids’ past, present and future locations in the cosmos, zapping them with the world’s most massive radar dishes, or considering how to rendezvous and perhaps even gently nudge an asteroid into lunar orbit, Bhaskaran thinks about how to collide with one.

NASA’s ARTEMIS mission reveals the Moon’s effect on the Solar Wind

 

Written by Bill Steigerwald
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – With the moon as the most prominent object in the night sky and a major source of an invisible pull that creates ocean tides, many ancient cultures thought it could also affect our health or state of mind – the word “lunacy” has its origin in this belief.

Now, a powerful combination of spacecraft and computer simulations is revealing that the moon does indeed have a far-reaching, invisible influence – not on us, but on the Sun, or more specifically, the solar wind.

This is a view of the moon transiting, or passing in front of, the Sun as seen from the STEREO-B spacecraft on Feb. 25th, 2007. The Sun is in false color, and the moon appears as a black disk on the upper right. NASA's STEREO mission consists of two spacecraft launched in October, 2006 to study solar storms. (Credit: NASA)

NASA’s GRAIL Spacecraft fly in Formation around the Moon at 3,600 MPH

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The act of two or more aircraft flying together in a disciplined, synchronized manner is one of the cornerstones of military aviation, as well as just about any organized air show. But as amazing as the U.S. Navy’s elite Blue Angels or the U.S. Air Force’s Thunderbirds are to behold, they remain essentially landlocked, anchored if you will, to our planet and its tenuous atmosphere. What if you could take the level of precision of these great aviators to, say, the moon?
