Each spacecraft has its own spacesuit. They are more comfortable than past suits, and advancement in material technologies allow us to do things like use touch screens. Both new suits also are designed to make it easier to see inside the spacecraft. -Suni

The Perseverance power source is an RTG (radioisotope thermoelectric generator) that can last anywhere from 10-15 years. However, there are other elements of the rover (electronics, mechanisms) that may not last as long but given the longetivity we've seen in previous missions, we hope Percy keeps the tradition alive of outliving expectations! - ML

The DART spacecraft will change the speed of Didymos B by a bit less than a millimeter per second. So, my question in return is how much warning time we have. If we had decades to a century of warning time, and could build as big an impactor as we want, we could move something a kilometer or two in diameter. if one of those made it through, we think it would cause civilizational collapse. With less warning time, we might need to use a nuclear device to deflect large asteroids. This is part of the impetus to find potential impactors early!
