October 3: A brilliant pairing of lights

The night of October 2 – 3 will see a brilliant pairing of lights in our night sky. Earth’s Moon and planet Mars will shine close together — only a smidgen over a degree apart — in the southeast. As viewed from the Medina, Ohio area, Moon and Mars will be nearest each other at 12:17 AM EDT. Don’t worry if you can’t stay up, the two will be a beautiful pair to behold all night long.

Our Moon will be a day past Full and in its Waning Gibbous phase, so it will be round and bright. Mars, while too distant to be seen as a disc by the unaided eye, is nearing an unusually close approach to Earth during its opposition and will shine like a coppery star. Mars will be nearest to Earth, at 62 million kilometers (38,525,014 miles) distant, on October 6 and it won’t be that close again until 2035.

Opposition refers to a time in their orbits when Mars (or another planet) is opposite the Earth from the Sun — around that time is when the two bodies, on concentric racetrack orbits around the Sun, pass each other and are at their closest and brightest.

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.”

InSight Mars lander’s first “selfie”

This is NASA InSight’s first selfie on Mars. It displays the lander’s solar panels and deck. On top of the deck are its science instruments, weather sensor booms and UHF antenna. The spacecraft used a camera on its robotic arm to take its first selfie – a mosaic made up of 11 images. This is the same imaging process used by NASA’s Curiosity rover mission, in which many overlapping pictures are taken and later stitched together. Visible in the selfie are the lander’s solar panel and its entire deck, including its science instruments. Image Credit: NASA/JPL-Caltech
