Visitors are welcome to Explore JPL to learn more about space exploration, robotics, and technology being developed at NASA’s Jet Propulsion Laboratory. Tickets for the popular, free event become available on Aug. 29 and go fast.NASA/JPL-Caltech

Celebrating its 90th anniversary this year, NASA’s Jet Propulsion Laboratory invites the public to its campus at the base of the San Gabriel Mountains in Southern California for an open-house event, Explore JPL. On Oct. 10 and 11, from 9:30 a.m. to 4 p.m. PDT, visitors will get the chance to visit JPL’s most iconic facilities and explore four thematic areas: Missions That Changed the World, Moon to Mars, In Flight, and Makerspace. 

Tickets are free but very limited and have gone quickly for past Explore JPL events. They will be available on the Explore JPL webpage at 9 a.m. PDT Saturday, Aug. 29, and will be distributed on a first-come, first-served basis, with a maximum of five tickets per requestor. Orders for more than five tickets may be subject to cancellation. Tickets will be provided for specific time slots and must be reserved for specific names. Attendees will not be admitted to JPL before the designated time printed on their ticket. 

A division of Caltech in Pasadena, California, JPL traces its origins to rocket-propulsion development in 1936. By 1958, the lab had built and helped launch America’s first satellite, Explorer 1. That same year, Congress established NASA, and JPL became a part of the agency. Since then, JPL has managed such historic missions as Voyager, Galileo, Cassini, the Mars Exploration Rover program, the Perseverance Mars rover, Europa Clipper, and many more.

Among other highlights, Explore JPL guests will get to: 

• Visit JPL’s legendary Space Flight Operations Facility, a National Historic Landmark where engineers send commands and receive data from spacecraft billions of miles away. 

• Discover the Spacecraft Assembly Facility and JPL Machine Shop, where precision spacecraft components are crafted. 

• See the latest cutting-edge innovations in robotics research, from autonomous lunar rovers to search-and-rescue robots. 

• Get up close with full-scale models of the Perseverance Mars rover, Voyager, and Galileo. 

• Step inside the Microdevices Laboratory to see how miniature technologies developed there are shaping the future of space exploration and Earth science. 

To attend Explore JPL, visitors must have their tickets in hand and anyone age 18 or over must show government-issued identification. Tickets are not transferable and cannot be sold. Children under age 2 do not require a ticket, but experiences at the event are not intended for very young guests. 

Visitors may not bring these items to JPL: weapons or explosives of any kind, incendiary devices, glass containers, alcohol, cannabis or illegal drugs, pets (except certified service animals), banners or signs, flags, boom boxes, air horns, musical instruments, and professional camera equipment with detachable telephoto lenses. Use of laser pointers or whistles is not allowed. No bags, backpacks, or hard-sided coolers are permitted, either, except small purses and diaper bags. Drones are not allowed to fly over JPL under any circumstances. Skates, skateboards, scooters, Segways, and bicycles are not permitted inside the event, as the venues are crowded with pedestrians. 

Vehicles entering JPL property are subject to inspection. Parking is free.

Our search for technosignatures - clear signs of advanced civilizations beyond Earth - takes many forms. Many are driven by the famous Drake equation, which attempts to estimate how many technological civilizations there are in the Milky Way. However, there’s a big fat question mark at the end of that equation in the form of a variable intended to account for the “longevity” of a civilization. And to be clear, that doesn’t mean how long the civilization itself survives. It simply means how long it actively creates a signature that is detectable by our current technology. A new paper, available in pre-print on arXiv from Oxford astrophysicist Brian C. Lacki, argues that, since the chances of us overlapping in time with any such civilization are miniscule, we’re much more likely to find the ruins of a “dead” civilization - and, surprisingly, the best place to do so might be in our own solar system.

If the Sun's fusion shut off right now, you would not notice for a very long time. The first stop is understanding the Sun itself: a vast pile of gravitating matter where fusion is so absurdly inefficient that, pound for pound, a compost heap beats it.

One of the hardest things to calculate for an asteroid is its mass - but it is such a critical feature. It determines how much of an impact it would have if it hits something, or how many resources are potentially available on it. But to accurately measure it we typically use optical sensing and a guesstimate of its density based on its spectral profile. A new paper suggests a completely novel way to use the Laser Interferometer Space Antenna (LISA) flagship mission to potentially provide highly accurate mass calculations for nearby asteroids without any change in hardware.
