I apologize, but I couldn't find any specific information regarding NASA seeking a lander battery tough enough to survive Venus. It's important to note that my training data only goes up until September 2021, and I don't have access to real-time information or updates on NASA's current projects or initiatives.
However, exploring the harsh environment of Venus is indeed a topic of interest for scientists and space agencies. Venus is known for its extreme temperatures, high download pikashow apk for andriod atmospheric pressure, and corrosive atmosphere, which make it challenging for technology to withstand. If NASA or other space agencies are working on missions to Venus, it is likely that they are developing specialized equipment and technology, including batteries, that can withstand these extreme conditions.
For the most up-to-date and accurate information on NASA's missions and initiatives, I recommend visiting NASA's official website or referring to reputable scientific sources for the latest news and developments related to Venus exploration.
