Science In A Minute: What is Infrared Light?
What is infrared light and how do we use it to study the universe? Infrared radiation, or infrared light, is a type of energy that we humans can't see but can feel as heat. All objects in the universe emit some level of infrared radiation, whether hot or cold, making an infrared telescope like NASA's Spitzer Space Telescope very useful in detecting objects that might seem invisible. For more information on the Spitzer Space Telescope go to www.nasa.gov/spitzer.
Science In A Minute: The Art of Spitzer Space Telescope
How do scientists turn data from NASA’s Spitzer Space Telescope into the incredible images we see? It's not as simple as just snapping a picture of the universe. There is a process for gathering the data from Spitzer and coding it so that colors and pictures can emerge from the data. The process can be lengthy, but well worth the breathtaking images we receive in the end.

NASA's Spitzer Space Telescope (Mission Overview)
After 16 years of unveiling the infrared universe, NASA's Spitzer Space Telescope has left a singular legacy. As one of NASA’s four Great Observatories -- a series of powerful telescopes including Hubble, Chandra and Compton that can observe the cosmos in different parts of the electromagnetic spectrum --Spitzer quickly became a pioneer in the exploration of the worlds beyond our human vision. From stars being born to planets beyond our solar system (like the seven Earth-size planets around the star TRAPPIST-1), Spitzer's science discoveries will continue to inspire the world for many years to come.

NASA’s New Planet Tracker, NEID
A new NASA-funded planet-hunting instrument has been installed on the WIYN telescope, on Arizona’s Kitt Peak. NEID (pronounced “NOO-id,” rhymes with fluid) is a spectrometer that is one of the first instruments of its kind with the precision to detect small, terrestrial planets around nearby stars. NEID will also confirm the presence of planets discovered by NASA’s TESS space telescope, and reveal details of their anatomy.
Eventually, scientists want to be able to find Earth-like planets around Sun-like stars, in an effort to find a world with life on it.

Neptune Moon Dance (animation)
See how the odd orbits of Neptune's inner moons Naiad and Thalassa enable them to avoid each other, as they race around the planet. Researchers call it a "dance of avoidance." An observer sitting on Thalassa would see Naiad in an orbit that varies wildly in a zig-zag pattern, passing by twice from above and then twice from below. This up, up, down, down pattern repeats every time Naiad gains four laps on Thalassa. This repeating pattern is called a resonance.
Marina Brozović, lead author of the new analysis, created this animation using Cosmographia, software made by NASA's Jet Propulsion Laboratory that is free to download. The analysis was conducted using Hubble Space Telescope observations. https://naif.jpl.nasa.gov/naif/cosmographia.html . Video credit: NASA/JPL-Caltech

NASA JPL Engineers Compete in Annual Pumpkin Carving Contest
Once a year at Halloween, hardworking JPL engineers put their skills to the test in a highly competitive pumpkin carving contest. The result: A pumpkin gently landed on the Moon, its retrorockets smoldering, while across the room a Nemo-inspired pumpkin explored the sub-surface ocean of Jupiter moon Europa. Suffice to say that when the scientists and engineers at NASA's Jet Propulsion Laboratory compete in a pumpkin-carving contest, the solar system's the limit. Take a look at some of the masterpieces from 2019. Now in its ninth year, the contest gives teams only one hour to carve and decorate their pumpkin though they can prepare non-pumpkin materials - like backgrounds, sound effects and motorized parts - ahead of time.

Darkness Surrounds Us: The Other 95% of the Universe (Live Public Talk)
Original Air Date: Oct. 17, 2019 All the material we can see is just a small fraction of the universe. The rest, a full 95 percent, is invisible and mysterious. These are the enigmatic dark matter and dark energy. While dark matter keeps things like galaxies together, dark energy acts in an opposite way – it pushes groups of galaxies apart and expands the universe itself. This event will discuss how astronomers are working to map the universe’s dark matter so they can see the effects of dark energy. The results could help us understand if the universe will expand at an accelerating rate forever. Host:

NASA InSight's Robotic Arm Helps Out its Mole on Mars
NASA’s InSight lander on Mars is trying to use its robotic arm to get the mission’s heat flow probe, or mole, digging again. InSight team engineer Ashitey Trebbi-Ollennu, based at NASA’s Jet Propulsion Laboratory in Pasadena, California, explains what has been attempted and the game plan for the coming weeks. The next tactic they'll try will be "pinning" the mole against the hole it's in.
The German Aerospace Center (DLR) built the mole. It is designed to dig under the Martian surface to measure heat flowing out of the planet. Scientists want this data to learn how Mars and other rocky planets form.

Listen to NASA's InSight at Work on Mars
NASA's InSight lander placed a seismometer on the Martian surface to study marsquakes. While it's found many, it has also detected other kinds of seismic signals, including some produced by the spacecraft itself. That includes wind gusts, InSight's robotic arm moving around and "dinks and donks," friction caused by parts inside the seismometer moving against each other as the temperature changes. Put on your headphones and you can hear sonifications of this seismic "noise" recorded on March 6, 2019, the 98th Martian day, or sol, of the mission. Around 2 p.m. local Mars time, the spacecraft's arm was moving and snapping pictures with its cameras, surveying InSight’s “workspace.” This audio would be too faint for the human ear to heart it on Mars. It's been sped up by 10 times and processed so you can hear the kinds of signals InSight sends back for its scientists to study.

What's Up: September 2019 Skywatching Tips from NASA
In this month's sky, look for lovely crescent Moons at the start and end of the month. The September equinox brings the beginning of fall in the Northern Hemisphere. And Mars is at solar conjunction, meaning it has disappeared from night skies! (When will it return?) Additional information about topics covered in this episode of What's Up, along with still images from the video, and the video transcript, are available at https://go.nasa.gov/2Hx3bMn Correction: The video states that the Moon will be waning at the beginning of the month and waxing at the end. In fact it is the opposite — the Moon is waxing at the beginning, and waning at the end. We regret the error. Credit: NASA/JPL-Caltech

Robert Downey Jr. Announces NASA's 'Rolling Stones Rock'
Before The Rolling Stones took the stage at the Rose Bowl Stadium for a concert on Aug. 22, 2019, actor Robert Downey Jr. announced to the crowd that a rock on Mars had been named for the band by NASA's Mars InSight lander team.
InSight’s retrorockets sent "Rolling Stones Rock" rolling about 3 feet (1 meter) as the spacecraft touched down on Mars on Nov. 26, 2018. It's the farthest NASA has seen a rock roll after landing a spacecraft on another planet. A little larger than a golf ball, the rock is about 2.2 inches (5.5 centimeters) in diameter and 1 inch (2.4 centimeters) in height. A series of divots marked its course after being set in motion by the landing. The Jet Propulsion Laboratory (JPL), a division of Caltech, manages InSight for NASA. JPL is located about three miles away from the Rose Bowl in Pasadena, California.

NASA Names “Rolling Stones Rock” on Mars
The team behind NASA's InSight lander has informally named a rock on Mars “Rolling Stones Rock” after the band.
A little larger than a golf ball, the rock appeared to have rolled about 3 feet (1 meter) on Nov. 26, 2018, propelled by InSight's retrorockets as the spacecraft touched down to study the Red Planet's deep interior. In images taken by InSight the next day, several divots in the orange-red soil can be seen trailing "Rolling Stones Rock." It's the farthest NASA has seen a rock roll while landing a spacecraft on another planet. For more about the mission, visit https://mars.nasa.gov/insight/ Video Credit: NASA/JPL-Caltech

NASA's Curiosity Mars Rover Explores Teal Ridge (360 View)
Curiosity captured this 360-degree panorama of a location on Mars called “Teal Ridge” on June 18, 2019. This location is part of a larger region the rover has been exploring called the “clay-bearing unit” on the side of Mount Sharp, which is inside Gale Crater. The scene is presented with a color adjustment that approximates white balancing to resemble how the rocks and sand would appear under daytime lighting conditions on Earth. Scientists are looking for signs that Mars could have supported microbial life billions of years ago, when rivers and lakes could be found in the crater.

Moon Struck! Celebrating Apollo's 50th Anniversary (Live Public Talk)
Original air date: Thursday, July 11, 7pm PT As part of the intense, decade-long effort that led to human footprints on the lunar surface, NASA’s Jet Propulsion Laboratory launched a series of robotic precursors to the Moon. It proved a formidable challenge — the first six missions failed, putting at risk the laboratory’s ambitions to explore the solar system. Meanwhile, Caltech — which operates JPL for NASA — established a laboratory in the mid-1960s to help develop the new techniques that would be needed for analyzing lunar samples. And once the Apollo 11 Moon rocks were on the ground, the Caltech researchers raced to contribute to the first stunning scientific results NASA shared with the world. This event will focus on understanding the supporting roles these institutions played in one of humanity's greatest achievements, and consider what might lie ahead in exploring the Moon. Take a journey back in time to learn how JPL found its way to success in the early days of the space race and how both Caltech and JPL have contributed to exploring and understanding our nearest celestial neighbor.

NASA Climbing Robot Scales Cliffs and Looks for Life
Robots can land on the Moon and drive on Mars, but what about the places they can't reach? Designed by engineers as NASA's Jet Propulsion Laboratory in Pasadena, California, a four-limbed robot named LEMUR (Limbed Excursion Mechanical Utility Robot) can scale rock walls, gripping with hundreds of tiny fishhooks in each of its 16 fingers and using artificial intelligence to find its way around obstacles. In its last field test in Death Valley, California, in early 2019, LEMUR chose a route up a cliff, scanning the rock for ancient fossils from the sea that once filled the area. The LEMUR project has since concluded, but it helped lead to a new generation of walking, climbing and crawling robots. In future missions to Mars or icy moons, robots with AI and climbing technology derived from LEMUR could discover similar signs of life. Those robots are being developed now, honing technology that may one day be part of future missions to distant worlds. Read more: https://go.nasa.gov/2SaMjyT
Landing NASA’s Mars 2020 Rover with Terrain Relative Navigation
The Mars 2020 mission is facing the most challenging landing yet on the Red Planet. It will touch down on Feb. 18, 2021, in Jezero Crater, a 28-mile-wide (45-kilometer-wide) expanse full of steep cliffs, boulder fields and other things that could boobytrap the landing. A new technology called Terrain Relative Navigation (TRN) will allow the spacecraft to avoid hazards autonomously. It's the closest thing to having an astronaut piloting the spacecraft, and the technology will benefit future robotic and human exploration of Mars.

First Likely Marsquake Heard by NASA's InSight
This video and audio illustrates a seismic event detected by NASA's InSight on April 6, 2019, the 128th Martian day, or sol, of the mission. Three distinct kinds of sounds can be heard, all of them detected as ground vibrations by the spacecraft's seismometer, called the Seismic Experiment for Interior Structure (SEIS): There's noise from Martian wind; the seismic event itself; and the spacecraft's robotic arm as it moves to take pictures. This event is the first likely marsquake recorded by the InSight team. Several other seismic events have been recorded but are much more ambiguous than this signal. The audio underscores just how seismically noisy the Martian surface can be and was produced from two sets of sensors included with SEIS. You can hear sounds from the Very Broad Band sensors from your left speakers and sounds from the Short Period sensors from your right speakers. Audio from both sets of sensors have been sped up by a factor of 60; the actual vibrations on Mars would not have been audible to the human ear. Playback on headphones or speaker system recommended for best experience.
