PRIVATE GROUP WANTS TO LAUNCH “CHEAPEST POSSIBLE” MISSION TO ALPHA CENTAURI

Summary from the TLDR newsletter

The Fermi Explorer mission aims to launch a spacecraft carrying a 1kg payload to Alpha Centauri so that it reaches the system in fewer than 80,000 years. It will knock two 'filters' off the Fermi paradox: that species won't want to send spacecraft beyond their home star, or species will find that interstellar transit is too difficult. This would leave only a few options for why our galaxy appears not to be littered with alien civilizations. The team wants to use existing technology to do something cheap and fast and launch by 2029.
