Pasadena, CA – The tubes carried in the belly of NASA’s Mars 2020 Perseverance rover are destined to carry the first samples in history from another planet back to Earth.
Future scientists will use these carefully selected representatives of Martian rock and regolith (broken rock and dust) to look for evidence of potential microbial life present in Mars’ ancient past and to answer other key questions about Mars and its history. Perseverance will land at Mars’ Jezero Crater on February 18th, 2021.
SpaceX Dragon Spacecraft launched Thursday heading to International Space Station with NASA Science Equipment
Pasadena, CA – A SpaceX Dragon cargo spacecraft is on its way to the International Space Station after launching at 11:29am CST Thursday, (December 5th, 2019. Dragon will deliver more than 5,700 pounds of NASA cargo and science investigations, including studies of malting barley in microgravity, the spread of fire, and bone and muscle loss.
The spacecraft launched on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida and is scheduled to arrive at the orbital outpost on Sunday, December 8th. Coverage of the spacecraft’s approach and arrival at the space station will begin at 3:30am CST on NASA Television and the agency’s website.

Pasadena, CA – Using new data from NASA’s Cassini spacecraft, researchers believe they have solved a longstanding mystery of solar system science: the length of a day on Saturn. It’s 10 hours, 33 minutes and 38 seconds.
The figure has eluded planetary scientists for decades, because the gas giant has no solid surface with landmarks to track as it rotates, and it has an unusual magnetic field that hides the planet’s rotation rate.
The answer, it turned out, was hidden in the rings.

Pasadena, CA – New observations by three of the world’s largest radio telescopes have revealed that an asteroid discovered last year is actually two objects, each about 3,000 feet (900 meters) in size, orbiting each other.
Near-Earth asteroid 2017 YE5 was discovered with observations provided by the Morocco Oukaimeden Sky Survey on December 21st, 2017, but no details about the asteroid’s physical properties were known until the end of June. This is only the fourth “equal mass” binary near-Earth asteroid ever detected, consisting of two objects nearly identical in size, orbiting each other. The new observations provide the most detailed images ever obtained of this type of binary asteroid.

Pasadena, CA – The puzzling appearance of an ice cloud seemingly out of thin air has prompted NASA scientists to suggest that a different process than previously thought — possibly similar to one seen over Earth’s poles — could be forming clouds on Saturn’s moon Titan.
Located in Titan’s stratosphere, the cloud is made of a compound of carbon and nitrogen known as dicyanoacetylene (C4N2), an ingredient in the chemical cocktail that colors the giant moon’s hazy, brownish-orange atmosphere.

Pasadena, CA – NASA’s Mars rover Curiosity is now selecting rock targets for its laser spectrometer — the first time autonomous target selection is available for an instrument of this kind on any robotic planetary mission.
Using software developed at NASA’s Jet Propulsion Laboratory, Pasadena, California, Curiosity is now frequently choosing multiple targets per week for a laser and a telescopic camera that are parts of the rover’s Chemistry and Camera (ChemCam) instrument. Most ChemCam targets are still selected by scientists discussing rocks or soil seen in images the rover has sent to Earth, but the autonomous targeting adds a new capability.
Pasadena, CA – How did life on Earth get started? Three new papers co-authored by Mike Russell, a research scientist at NASA’s Jet Propulsion Laboratory, Pasadena, CA, strengthen the case that Earth’s first life began at alkaline hydrothermal vents at the bottom of oceans.
Scientists are interested in understanding early life on Earth because if we ever hope to find life on other worlds — especially icy worlds with subsurface oceans such as Jupiter’s moon Europa and Saturn’s Enceladus — we need to know what chemical signatures to look for.
