( CNN ) -- Felix Baumgartner jumped from the edge of space . James Cameron plunged to the ocean 's lowest depths . Baumgartner broke the sound barrier . Cameron discovered an `` alien world . '' Call them daredevils , explorers , neither or both . No matter what , their record-breaking solo feats , backed up by teams of specialists , literally raised and lowered the bar for human achievement . So , for others aspiring to chart new terrain , what 's next ? We asked for your ideas . Journey to the center of the Earth . Martin Samuels and John O'Connor wrote us on Facebook , saying it 's time to work on getting lower . Way , way lower . `` Journey down in to the center of Earth , '' wrote Samuels . O'Connor added , `` Jules Verne for real ! '' That may be a very , very , very long way away , but downward steps are already being taken in that direction . A new $ 1 billion mission plans to drill 3.7 miles beneath the sea floor to reach the Earth 's mantle , a nearly 1,900-mile-thick layer of slowly deforming rock between the crust and the core , which makes up the majority of the planet . What we learn below can go a long way toward showing us what 's above . The deepest crack found in the Earth 's crust , on the Caribbean Sea floor , included signs of life -- which could indicate that alien life could exist on other planets , according to NASA . Walk on Mars . `` Obviously , the first person to set foot on Mars is the next big story , '' wrote Matt James Tiberius Kazan . Again , a far jump ( ha ha ) from anything Baumgartner and Cameron have done , and more in the realm of astronauts ' incredible achievements -- but , again , a big new goal explorers are working on . In fact , it could happen within 20 to 30 years , according to Charles Elachi , director of NASA 's Jet Propulsion Laboratory . `` I think engineering-wise , we know how to do it to some level . We still need a lot of development and a few inventions to do that , '' Elachi told CNN . `` So at the end it would become a question of national will if we want to keep our exploration , expand our vision and expand our exploration in the next 20 to 30 years . '' In the meantime , NASA is celebrating the success of the Mars rover Curiosity . Individual Atmosphere Re-entry . Much closer to home , Andrew Creech writes , `` the next step is individual atmosphere re-entry . That would be an amazing feat ! '' It would -- and Baumgartner 's jump may have gotten experts closer to making that happen . `` The long-term hope is that we can one day develop a suit that would allow a human to reenter the atmosphere from space without the help of a spaceship , '' Forbes wrote . In a blog post before Baumgartner 's jump , Forbes said if the event was successful it would `` be a big step forward . '' Re-entering Earth 's atmosphere can be like splashing into a lake , the Federal Aviation Administration explains . It 's `` a dense , fluid medium , which , at orbital velocities , is not all that different from a lake 's surface . '' Astronauts have to hit the atmosphere at a precise angle and speed to avoid `` a big 'splash , ' which would mean a fiery end , '' or a too shallow entry , which could send them skipping `` off the atmosphere and back into the cold of space . This subtle dance between fire and ice is the science of atmospheric re-entry . '' Baumgartner 's 100-pound pressurized suit and helmet helped him survive the lethally thin atmosphere and intense cold of near-space . One day , the hope is , a suit could help save the lives of astronauts forced to bail out of a malfunctioning rocket on its way to space . Politicians cooperate . To little surprise , some of our social media responses focused on politics . Politicians should `` go where no one has gone before and start cooperating with each other , '' wrote Andreas Bojesen . `` A third party nominee ascends to the presidency ! '' wrote Michael J. Simmons . The tech behind the Stratos jump . What ideas do you have ? Post comments below or join the discussions at Facebook and Twitter .
