A conversation with Ann Druyan and a fix for InSight
The European Space Agency’s Rosetta spacecraft snapped this image of the Earth’s night side during a 2007 slingshot past our planet. Rosetta was over the Indian Ocean at the time; India is visible at center.
As a global society, we achieve great things when we work together. Right now, due to COVID-19, we have to work together by staying apart. Whether you're in isolation or not, consider taking this time to explore what we know about this cosmos of ours. There is much to be known.

Like the rest of the world, the space community has been affected by COVID-19. All NASA employees except mission-essential personnel are working remotely. Europe has taken similar measures and suspended its launches. Even Buzz Aldrin is quarantined at home. It’s unclear how severely COVID-19 will affect upcoming mission schedules, but NASA officials say at least one mission is still on schedule for now: NASA’s Perseverance rover.
There are signs that NASA’s latest efforts to save the heat-flow probe aboard its Mars InSight lander may be working. The self-hammering instrument, known as the mole, has unsuccessfully been trying to bury itself since March 2019. Engineers are using InSight’s robotic scoop to press down on the top of the mole while it hammers. Pictured: InSight presses down on the mole with its robotic arm. Image credit: NASA/JPL
NASA sent out a media accreditation notice for the first orbital human spaceflight from the U.S. since the end of the space shuttle program in 2011. As soon as mid-to-late May, a Crew Dragon carrying astronauts Bob Behnken and Doug Hurley will launch to the International Space Station. The highly anticipated flight will mark the end of NASA’s sole reliance on the Russian Soyuz vehicle for station crew transport.
The inaugural flight of China’s Long March 7A rocket ended in failure, apparently destroying a classified satellite in the process. It’s unclear how the incident will impact other areas of China’s space program. The Long March 5, which will be needed to launch China’s first Mars mission this summer, uses common first-stage components but different upper-stage engines.
When NASA astronauts make their first flight to the lunar surface as part of the agency’s Artemis program—currently scheduled for 2024—they won’t be making a pit stop at the Gateway, a small, yet-to-be-built lunar space station. NASA officials say they are still committed to building the Gateway later, but that it is no longer in the “critical path” for the first Moon landing.
Correction: Last week, The Downlink reported that NASA’s Orion spacecraft was back at Kennedy Space Center in Florida, following several months of testing in Ohio ahead of a 2021 test flight. NASA has since removed the article we linked to, and clarified that the spacecraft will not ship to Florida until 23 March.
From The Planetary Society
In case you missed it, last week’s episode of Planetary Radio features a conversation with the renowned science communicator Ann Druyan about the latest season of Cosmos: Possible Worlds, and her new companion book of the same name. You can also read a transcript of the episode. Pictured: A scene from the season premiere depicts astronauts descending to the moon of a possible world.

Over the next week you’ll be able to see Venus bright in the sky after sunset. Mars, Jupiter, and Saturn will be visible in the predawn sky. Uranus will also be visible after sunset, but you’ll need binoculars or a telescope to spot it.
Wow of the Week
From The Rogue Astronaut on Twitter: “Harder to find than at night (that’s an understatement!) but if you know where to look, the planets, in this case Jupiter, can be seen during daylight hours!” Believe it or not, you can even see one of Jupiter’s moons in this image: the tiny dot to the right of Jupiter is its moon Europa.
