The image features the planet’s trademark Great Red Spot and a more intense color palette in the clouds swirling in the planet’s turbulent atmosphere than seen in previous years.

Among the most striking features in the image are the rich colors of the clouds moving toward the Great Red Spot. This huge anticyclonic storm is roughly the diameter of Earth and is rolling counterclockwise between two bands of clouds that are moving in opposite directions toward it.

As with previous images of Jupiter taken by Hubble, and other observations from telescopes on the ground, the new image confirms that the huge storm which has raged on Jupiter’s surface for at least 150 years continues to shrink. The reason for this is still unknown so Hubble will continue to observe Jupiter in the hope that scientists will be able to solve this stormy riddle. Much smaller storms appear on Jupiter as white or brown ovals that can last as little as a few hours or stretch on for centuries.

The worm-shaped feature located south of the Great Red Spot is a cyclone, a vortex spinning in the opposite direction to that in which the Great Red Spot spins. Researchers have observed cyclones with a wide variety of different appearances across the planet. The two white oval features are anticyclones, similar to small versions of the Great Red Spot.

The Hubble image also highlights Jupiter’s distinct parallel cloud bands. These bands consist of air flowing in opposite directions at various latitudes. They are created by differences in the thickness and height of the ammonia ice clouds; the lighter bands rise higher and have thicker clouds than the darker bands. The different concentrations are kept separate by fast winds which can reach speeds of up to 650 kilometers per hour.

These observations of Jupiter form part of the Outer Planet Atmospheres Legacy (OPAL) program, which began in 2014. This initiative allows Hubble to dedicate time each year to observing the outer planets and provides scientists with access to a collection of maps, which helps them to understand not only the atmospheres of the giant planets in the Solar System, but also the atmosphere of our own planet and of the planets in other planetary systems.

Artemis: Twin sister of Apollo

NASA’s Artemis Logo and Identity

NASA’s new Artemis Program identity revealed.

We go now to the Moon, not as a destination, but as a proving ground for all the technology, science, and human exploration efforts that will be critical for missions to Mars. On the lunar surface we will pursue water ice and other natural resources that will further enable deep space travel. From the Moon, humanity will take the next giant leap to Mars.

NASA has led the charge in space exploration for 60 years, and as we mark the 50th anniversary of the first Moon landing, the agency is preparing for its next giant leap with the Artemis program.

Artemis, named after the twin sister of Apollo who is also the Goddess of the Moon and the hunt, encompasses all of our efforts to return humans to the Moon – which will prepare us and propel us on to Mars. Through the Artemis program, we will see the first woman and the next man walk on the surface of the Moon. As the “torch bringer,” literally and figuratively, Artemis will light our way to Mars.

With this in mind, NASA is unveiling the new Artemis program identity, a bold look that embodies the determination of the men and women who will carry our missions forward. They will explore regions of the Moon never visited before, unlock mysteries of the Universe and test the technology that will extend the bounds of humanity farther into the Solar System.

This new identity draws inspiration from the Apollo program logo and mission patch. Using an “A” as the primary visual and a trajectory from Earth to the Moon, we honor all that the Apollo program achieved. However, through Artemis we will forge our own path, pursue lunar exploration like never before, and pave the way to Mars.

With Earth Blue, Rocket Red and Lunar Silver for colors, every part of the identity has meaning:

THE A: The A symbolizes an arrowhead from Artemis’ quiver and represents launch.
TIP OF THE A: The tip of the A of Artemis points beyond the Moon and signifies that our efforts at the Moon are not the conclusion, but rather the preparation for all that lies beyond.
EARTH CRESCENT: The crescent of the Earth at the bottom shows missions from humanity’s perspective. From Earth we go. Back to Earth all that we learn and develop will return. This crescent also visualizes Artemis’ bow as the source from which all energy and effort is sent.
TRAJECTORY: The trajectory moves from left to right through the crossbar of the “A” opposite that of Apollo. Thus highlighting the distinct differences in our return to the Moon. The trajectory is red to symbolize our path to Mars.
MOON: The Moon is our next destination and a stepping stone for Mars. It is the focus of all Artemis efforts.

Don’t miss the July 2 total solar eclipse, online or via NASA TV

The corona holds the answers to many of scientists’ outstanding questions about the Sun’s activity and processes. This photo was taken during the total solar eclipse on Aug. 21, 2017.

Be sure to be watching July 2 at 4:00 PM EDT as the total solar eclipse is presented live from Chile, via San Francisco’s Exploratorium. You will not be able to directly see the eclipse from the USA; the total solar eclipse will be visible from a narrow part of the South Pacific Ocean, Chile, and Argentina.

The Exploratorium will be bringing the total solar eclipse to you, no matter where you are. The have sent a team to Chile to broadcast from within the path of totality. Enjoy this full, unnarrated view of the eclipse from the telescopes at the National Science Foundation’s Cerro Tololo Observatory.

Live Coverage – Broadcast Style:
https://www.exploratorium.edu/video/total-solar-eclipse-2019-live-coverage

NASA has partnered with the Exploratorium to provide the coverage which it will livestream: three views via separate players on the agency’s website (all times EDT):

Live views from telescopes in Vicuna, Chile, without audio, from 3 to 6 PM
A one-hour program with live commentary in English, from 4 to 5 PM
A one-hour program with live commentary in Spanish, from 4 to 5 PM

NASA Television will also carry the English-language program on its public channel. Both programs will feature updates from NASA’s Parker Solar Probe and Magnetospheric Multiscale missions.

Mission’s end for “Oppy”

February 12, 2019 — One of the most successful and enduring feats of interplanetary exploration, NASA’s Opportunity rover mission is at an end after almost 15 years exploring the surface of Mars and helping lay the groundwork for NASA’s return to the Red Planet.

The Opportunity rover stopped communicating with Earth when a severe Mars-wide dust storm blanketed its location in June 2018. After more than a thousand commands to restore contact, engineers in the Space Flight Operations Facility at NASA’s Jet Propulsion Laboratory (JPL) made their last attempt to revive Opportunity Tuesday, to no avail. The solar-powered rover’s final communication was received June 10.

“It is because of trailblazing missions such as Opportunity that there will come a day when our brave astronauts walk on the surface of Mars,” said NASA Administrator Jim Bridenstine. “And when that day arrives, some portion of that first footprint will be owned by the men and women of Opportunity, and a little rover that defied the odds and did so much in the name of exploration.”

Designed to last just 90 Martian days and travel 1,100 yards (1,000 meters), Opportunity vastly surpassed all expectations in its endurance, scientific value and longevity. In addition to exceeding its life expectancy by 60 times, the rover traveled more than 28 miles (45 kilometers) by the time it reached its most appropriate final resting spot on Mars – “Perseverance Valley.”

“For more than a decade, Opportunity has been an icon in the field of planetary exploration, teaching us about Mars’ ancient past as a wet, potentially habitable planet, and revealing uncharted Martian landscapes,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate. “Whatever loss we feel now must be tempered with the knowledge that the legacy of Opportunity continues – both on the surface of Mars with the Curiosity rover and InSight lander – and in the clean rooms of JPL, where the upcoming Mars 2020 rover is taking shape.”
