ESA successfully completes first parachute test for 2020 ExoMars missionEarly in March the European Space Agency successfully completed the first of a series of parachute tests for its 2020 ExoMars rover mission.
The focus of the latest test, conducted in sub-zero conditions in Kiruna, Sweden earlier this month, was the 35 m-diameter second main parachute. The test demonstrated the deployment and inflation of the parachute with its 112 lines connected to a drop test vehicle, via the deployment of a smaller 4.8 m-wide pilot chute.
This test only tested the parachutes deployment system. They still need to do this test at high altitudes to duplicate Mars’ conditions using high-altitude balloons.
When ExoMars reaches Mars, the parachute will act to slow the spacecraft down during descent. For the actual landing, they will be using systems designed and built by the Russians.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Here’s a to-the-point account of how pork distribution takes the better out of ESA’s space ambitions:

Ideally, you’d ask the Germans to do it all! But they only pay 20% of ESA’s budget, so the others have to somehow make 80% of the mission. So Sweden, well we could at least drop a parachute there (unless it gets shot before landing).
