BepiColombo Spots Earth and the Moon

BepiColombo Spots Earth and the Moon
Europe and Japan's BepiColombo spacecraft took these images of Earth and the Moon in early March 2020 as it sped towards an Earth flyby on 10 April. Before it can enter Mercury orbit in 2025, BepiColombo, which launched in 2018, must make 1 flyby of Earth, 2 flybys of Venus, and 6 flybys of Mercury.

Facts Worth Sharing

Mercury Getting to Mercury isn’t easy. To reach the right speed to enter orbit around the innermost planet, BepiColombo has to make 1 flyby of Earth, 2 flybys of Venus, and 6 flybys of Mercury. The spacecraft launched in 2018 and will arrive in orbit in 2025.  

Mission Briefings

Jupiter as seen by Hubble Space Telescope, 2017

Jupiter as seen by Hubble Space Telescope, 2017
This image of Jupiter was taken by the Hubble Space Telescope when the planet was closest to Earth in 2017. The Great Red Spot appears on the left side, along with a smaller, reddish storm in the lower right dubbed "Red Spot Jr."

Solar System NASA kicked off a month-long celebration leading up to the Hubble Space Telescope’s 30th birthday. Hubble launched aboard Space Shuttle Discovery on 24 April 1990. One fun birthday feature allows you to view images that Hubble captured on your birthday. Pictured: An image of Jupiter taken by Hubble on this day, 3 April, in 2017. 

Uranus Scientists published new findings about Uranus using data collected when NASA’s Voyager 2 spacecraft flew by the planet in 1986. For just 60 seconds of its 45-hour-long encounter, Voyager 2 appears to have flown through a plasmoid—a bubble inside of Uranus’s magnetic field. The findings have implications for how giant planets lose their atmospheres.

Exoplanet CHEOPS, the European Space Agency’s CHaracterising ExOPlanet Satellite, has completed its commissioning process and is now ready for science operations. CHEOPS, which launched in late 2019, will precisely measure the diameters of known exoplanets. Learn more about why and how we study exoplanets, and The Planetary Society’s exoplanets research.

Moon NASA selected SpaceX as the first cargo delivery firm for the Gateway, a small space station the agency is planning in lunar orbit. SpaceX will build a larger version of its Dragon crew and cargo vehicle called the Dragon XL for the supply missions. Upon delivering supplies to the Gateway, Dragon XL would remain docked there for up to a year.

From The Planetary Society

tpslogo If you’re working from home now, you’re likely using video chats more than ever. Since some services like Zoom allow you to create virtual backgrounds, our Solar System Specialist Emily Lakdawalla has curated a collection of space images that you can use as backgrounds to help you show off your affinity for space.

tpslogo Last week Planetary Society members were invited to a special space policy briefing telecon with Planetary Society CEO Bill Nye, Chief Advocate and Senior Space Policy Advisor Casey Dreier, Chief of Washington Operations Brendan Curry, and Planetary Radio host Mat Kaplan. You can watch the video recording of the telecon to hear their discussion and analysis of the latest space policy developments happening in Washington, D.C., and their answers to members’ questions.

Do you love to make art? Is creativity something you’re practicing to get through these difficult times? We want to hear from you! Every issue of our quarterly print magazine, The Planetary Report, features space art on the back cover. We also occasionally feature space art in this weekly newsletter, The Downlink, when we come across pieces that we love. We feature our members everywhere we can, so we’re calling out to you to send us your space-inspired artwork. You can send your work to our Community Engagement lead at kate.howells@planetary.org, or by replying to this email.

What’s Up

Venus Venus continues to put on a spectacular show, shining brightly in the evening sky above the Moon. If you’re up early enough, you can also catch Jupiter, Mars, and Saturn in the pre-dawn sky.  

Wow of the Week

Solar system scale model project

Solar system scale model project
Planetary Society member David Haynes, of Canberra, Australia, sent us this suggestion for a fun and educational space activity for kids. David created scale models of the planets in our solar system, at a scale of 1 cm to 100,000 km. You can add to this activity if you’re able to find a wide-open space like a country road, where you can lay the planets out at their relative distances from the Sun. At this scale, Neptune is 450 m from the Sun. David says: “Experiencing Earth in this context (not to mention the other star systems and galaxies) helps give a cosmic perspective to drive home how special our home world is—harbouring life in the immense void.”

Do you have a suggestion for the Wow of the Week? We’re looking for space-related art, music, gadgets, quotes, fashion, burning questions, sci-fi passages, or anything else that will make our readers go “Wow!” Send us your idea by replying to this email.
