NASA’s Insight Lander will give scientists look at Mars below the surface, study Marsquakes

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Starting next year, scientists will get their first look deep below the surface of Mars.

That’s when NASA will send the first robotic lander dedicated to exploring the planet’s subsurface. InSight, which stands for Interior Exploration using Seismic Investigations, will study marsquakes to learn about the Martian crust, mantle and core.

Doing so could help answer a big question: how are planets born?

NASA’s Mars InSight Lander will study the Deep Interior of Mars

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars InSight lander team is preparing to ship the spacecraft from Lockheed Martin Space in Denver, where it was built and tested, to Vandenberg Air Force Base in California, where it will become the first interplanetary mission to launch from the West Coast. The project is led by NASA’s Jet Propulsion Laboratory in Pasadena, California.

NASA has a long and successful track record at Mars. Since 1965, it has flown by, orbited, landed and roved across the surface of the Red Planet. What can InSight — planned for launch in May — do that hasn’t been done before?

NASA looks to fund concepts for missions to Saturn’s Moon Titan and a Comet

 

Written by Dwayne Brown / Laurie Cantillo
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA has selected two finalist concepts for a robotic mission planned to launch in the mid-2020s: a comet sample return mission and a drone-like rotorcraft that would explore potential landing sites on Saturn’s largest moon, Titan.

The agency announced the concepts Wednesday, following an extensive and competitive peer review process. The concepts were chosen from 12 proposals submitted in April under a New Frontiers program announcement of opportunity.

NASA’s studying of Earth will help to discover Life on another Planet

 

Written by Carol Rasmussen
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – As a young scientist, Tony del Genio of NASA’s Goddard Institute for Space Studies in New York City met Clyde Tombaugh, the discoverer of Pluto.

“I thought, ‘Wow, this is a one-time opportunity,'” del Genio said. “I’ll never meet anyone else who found a planet.”

That prediction was spectacularly wrong. In 1992, two scientists discovered the first planet around another star, or exoplanet, and since then more people have found planets than throughout all of Earth’s preceding history.

NASA’s Spitzer Space Telescope data shows Super Earth 55 Cancri e could have an Atmosphere similar to Earth’s

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA –  Twice as big as Earth, the super-Earth 55 Cancri e was thought to have lava flows on its surface. The planet is so close to its star, the same side of the planet always faces the star, such that the planet has permanent day and night sides.

Based on a 2016 study using data from NASA’s Spitzer Space Telescope, scientists speculated that lava would flow freely in lakes on the starlit side and become hardened on the face of perpetual darkness. The lava on the dayside would reflect radiation from the star, contributing to the overall observed temperature of the planet.

The super-Earth exoplanet 55 Cancri e, depicted with its star in this artist's concept, likely has an atmosphere thicker than Earth's but with ingredients that could be similar to those of Earth's atmosphere. (NASA)

NASA explores concept for Venus Rover

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A good watch can take a beating and keep on ticking. With the right parts, can a rover do the same on a planet like Venus?

A concept inspired by clockwork computers and World War I tanks could one day help us find out. The design is being explored at NASA’s Jet Propulsion Laboratory in Pasadena, California.

The Automaton Rover for Extreme Environments (AREE) is funded for study by the NASA Innovative Advanced Concepts program. The program offers small grants to develop early stage technology, allowing engineers to work out their ideas.

AREE is a clockwork rover inspired by mechanical computers. A JPL team is studying how this kind of rover could explore extreme environments, like the surface of Venus. (NASA/JPL-Caltech)

NASA looks at studying Venus using CubeSats

 

Written by Lori Keesey
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Venus looks bland and featureless in visible light, but change the filter to ultraviolet, and Earth’s twin suddenly looks like a different planet. Dark and light areas stripe the sphere, indicating that something is absorbing ultraviolet wavelengths in the planet’s cloud tops.

A team of scientists and engineers working at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, has received funding from the agency’s Planetary Science Deep Space SmallSat Studies, or PSDS3, program to advance a CubeSat mission concept revealing the nature of this mysterious absorber situated within the planet’s uppermost cloud layer.

As seen in the ultraviolet, Venus is striped by light and dark areas indicating that an unknown absorber is operating in the planet’s top cloud layer. The image was taken by NASA’s Pioneer-Venus Orbiter in 1979. (NASA)

NASA’s Cassini Spacecraft’s 20 Year Mission to come to a close

 

Written by Steven Siceloff
NASA’s Kennedy Space Center

NASA - National Aeronautics and Space AdministrationFlorida – As NASA’s Cassini spacecraft spends its last few weeks in orbit around Saturn before making a controlled impact with the planet in what NASA dubbed Cassini’s “Grand Finale,” some of those who helped launch the mission 20 years ago are thrilled with the success of the massive probe they helped dispatch to one of the solar system’s most intriguing worlds.

“There’s just a real sense of fulfillment associated with being part of a launch team, particularly something as big as Cassini and as complicated as Cassini is and the whole makeup of the whole Cassini team,” said Ray Lugo, launch director for Cassini. “It was a big community of folks and everybody had to do their part to make sure that mission got off right.”

NASA says Habitable “Tatooine” type planets could be possible

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – With two suns in its sky, Luke Skywalker’s home planet Tatooine in “Star Wars” looks like a parched, sandy desert world. In real life, thanks to observatories such as NASA’s Kepler space telescope, we know that two-star systems can indeed support planets, although planets discovered so far around double-star systems are large and gaseous. Scientists wondered: If an Earth-size planet were orbiting two suns, could it support life?

It turns out, such a planet could be quite hospitable if located at the right distance from its two stars, and wouldn’t necessarily even have deserts.

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A mechanical rover inspired by a Dutch artist. A weather balloon that recharges its batteries in the clouds of Venus.

These are just two of the five ideas that originated at NASA’s Jet Propulsion Laboratory in Pasadena, California, and are advancing for a new round of research funded by the agency.

In total, the space agency is investing in 22 early-stage technology proposals that have the potential to transform future human and robotic exploration missions, introduce new exploration capabilities, and significantly improve current approaches to building and operating aerospace systems.
