The second stage of a Falcon 9 rocket launched in 2017 re-entered the atmosphere over Mexico, breaking up and creating a show of fiery lights in the sky. Plus, dead stars with possibly living planets, more on moon formation, more launches, more launch failures, and a review of “The Apollo Murders” by Chris Hadfield.
A NASA-funded simulation of early Mars revealed that the climate three billion years ago on the red planet was very similar to Earth now, with a stable ocean in the northern hemisphere. This new timeline would have given life another 500 million years to develop. Plus, a dwarf galaxy, Saturn’s aurorae, a Soyuz launch, and an interview with Dr. Adam Szabo, mission scientist for the Parker Solar Probe.
The Rocket Roundup team takes a look back at the rockets that launched in 2021, with a review of the statistics and some highlights (including that one telescope that could have ruined Christmas).
Researchers hypothesize that blobs in post-Big Bang fields of energy, known as Q-balls, could explain how matter came to dominate over antimatter in our Universe, and they plan to use gravitational waves to find their evidence. Plus, a crewed launch to the ISS features Japanese tourists, NASA selects the latest astronaut class, and What’s Up is the Geminids.
In this week’s Rocket Roundup, we have more Starlink, European navigation satellites, a Chinese company launching to orbit again, a large U.S. government satellite, and a sounding rocket from Sweden. Plus, this week in rocket history, we look back at Little Joe 2.
During this jam-packed episode of Rocket Roundup, we cover several Chinese launches, SpaceX’s launch of NASA’s DART mission to hit an asteroid, and Russia’s launch of a military satellite. Plus, this week in rocket history, we look back at Pioneer 10’s encounter with Jupiter.
