Bob Zimmerman spoke on the John Batchelor radio program on Thursday night (podcast) about the following topics:

• Curiosity is out of safe mode, though communications in April will be very limited.
• Jeff Bezos has recovered from the ocean floor two first stage engines from an Apollo Saturn 5 rocket.
• The company that launches the Proton rocket commercially has lowered its prices.
• Voyager 1 has almost? maybe? left the solar system.
