assembled it at goddard and tested at goddard and put it in environmental chambers matching the surface of mars and tested the of of software and brought to jepropulsion lab and this image shows sam. that's the gold coated box about the size of a microwave oven and gently lowered into the rover. rover is upside down at that point. and we lowered sam into it and did more testing. we put a rover in fact in a big environmental chamber at jpl d when we were sure everything was perfect, then the rover was ready to ship to the cape and everything was launched. to see everybody there in bunny suits. the reason they are in the white suits is we didn't want to bring our skin oils and everything else to mars because then jen would have to report that we were finding things that looked like they came from chris webster or someone else in the room at jpl. it took a lot of work and great team work and several nationsjoining us. >> when you were talking about leads to one of the social moda questions. how did you vair fight experiments have not been compromised before reaching on mars or after landin

we put this instrument together at nasa-goddard. chris webster's team at jet ropulsion labs did the spectrometer. this morning they were calling in because they were supporting operations of our instruments from tuluth. we spent several years putting this together, testing it at goddard, put in it environmental chambers to match the conditions we'd have on the surface of mars. tested out the scripts, the software we were going to run on mars and then we brought toyota jet propulsion labs and this image you see shows sam, that's the gold-coated box about the size of a microwaven of being gently lowered into the rover. the rover is upside down at that point. we lowered sam into it and then did some more test, put the whole rover in a big environmental chamber at j.p.l. when we were sure everything was perfect, then the rohr was ready to ship to the cape and everything got launch. you see everyone in bunny suits. the reason they're in the white suit, we did not want to bring our skin oils and everything else to mars because then jen wo

na nasa goddard chief signtive jim garvin. >> we thought maybe these minerals told us something.e got the holy grail. >> reporter: the rover found the molecules when it drills into rock in an ancient lake bed. in 2013, the rover found hints of other organic molecules nearby and kept looking. >> organic material is associated with life on earth. everything that we know on earth associated with biology is composed of organic molecules. >> reporter: nasa astro biologist jennifer eigenbrode says curiosity has confirmed seasonal increases of methane gas on mars. on eth, it comes from animal, human and plant life, none of which has been found on mars. >> there's a mystery as to why it's there, where it's from, and that's what future missions are going to figure out. >> reporter: because it could be a sign of life? >> it could be a sign of life. >> reporter: while nasa scientists caution there could be other explanations for both the methane gas and organic molecules, they say they now know where to look for further signs of life. >> we're the miners of the organics that might tell us a

it will be warm in the east bay, where 90s are expected. 92 in goddard, oakland will be 78 for the afternoontoday. >>> that will do it for us but the party is about to get started. >> the balloons are out. all that blue and gold and the fans will make it even more fun. >>> we start our live coverage at 10:00 this morning. >> have fun and bring your sunblock. >>> good morning to our viewers in the west. it is tuesday, june 12th, 2018. welcome to "cbs this morning." president trump and north korean leader kim jong-un wrap up their historic meeting by signing a joint declaration. the agreement calls for a complete denuclearization of the korean peninsula but has few details. we'll discuss what it all means with senator lindsey graham. "face the nation" moderator margaret brennan and the president of eurasia group. >> and suv concerns and how automakers are responding. >>>

to tell us more about the earth-shaking discovery, we spoke to a bio geochemist from nasa goddard spaceer and the lead author of the study on these findings. >> essentially, we found organic matter in rocks from an ancient lake on mars. that lake was around 3.5 billion years ago. so that planet was a lot different back then, and we have had other clues that tell us pretty much their water was around, their nutrients were around and energy sources around. and now we have evidence of organic material. everything that life would need to be happy was there. we just don't know if there was life. the organic materials that we found could be from life, or perhaps they were just possible food for life when the lake was around. either way, it still bodes well for the search for life going forward. emily: so let's take it one step further. is it possible that some form of life still exists there? does this give you any information about that? >> well, we are not really sure if life has ever existed, but if life ever got established, it was probably really early on in the mars history, around the

iny catherine goddard, born 17 and already owned the newspaper. she was a single woman businesswoman, so she printed the declaration. this creating a democracy after having been royal colonies was a big change. as john and abigail adams would observe in the. then the period of crafting declaration, it would introduce raised and unmet expectations about independence. you are familiar with this correspondence between john and abigail adams in the spring of 1776. remember the lady -- be more generous and favorable to them then your ancestors. do not put such unlimited power in the hands of husbands. were member, all men would be tyrants if they could. men would beall tyrants if they could. we will not hold ourselves bound by any laws in which we have no voice or representation. that your sex is naturally tyrannical is a truth so thoroughly established as to admit no dispute, but -- put it out of the power and the -- dispute. put it out of the power and use the missions in the lawlessness to grant us unity. flagwas abigail's feminist to some people. i

on the other hand some of therii datathat goes to goddard for the robotic capability but my point is the answer is yes we have a great working relationship with the answer -- with department of defense we are working side-by-side giving data to our centers to make sure our assets are protected. i anticipate that will continue. as general hyten said when we moved to the day where commerce is at the home of faith situational awareness and traffic management it is absolutely true the department of defense low keep the catalog for their own purposes so it is possible nasa would continue to have personnel. no decision has been made maybe we could combine all data to get a better picture with another agency and if it did happen we would want powerful that commerce and keep them and dod as well but this is way early and i'm determined at this point be back in my last question, just to mention both by the administrator and the congressman with the catalog -based objects to take advantage of to avoid collisions andan faith, if the department of commerce takes over that responsibility and othe

on the other hand, some of the data goes to cara which is over at goddard for the robotics capabilities. my point is, yes, we have a great working relationship with the department of defense. we have our nasa died feeding data to our centers making sure that our assets are protected. i anticipate that will continue . if we moved to a day where commerce is at the helm of traffic management and space situational awareness, the department of defense will continue to keep the catalog because they need to. it's possible nasa would continue to have this possibly up the day >>> -- at [ inaudible ] if this did happen, we would want folks at commerce as well as dod. this is early and undetermined at this point two >> thank you adminstrator bridenstine. i want to ask my last question to you. this is already been spoken about in regard to the catalog of space objects to take advantage of to avoid collisions in space. if the department of commerce takes over that possibility and others that are now assumed by the department of defense, do you see any diminution in the quality of product, any diminu

on the other hand, some of the data goes to cara over at goddard for the robotic capabilities, but i guess my point is to your question, the answer is yes, we have a great working relationship with the department of defense. we have our nasa personnel working side by side with their folks, feeding data to our centers to make sure that our assets are protected and i anticipate that that will continue as general hyten has side, when we move to a day where commerce is at the he hellm-- helm, they'll keep the catalog, so it's possible that nasa would have our personnel. no decision has been made and maybe we could take the data from dod and combine it over at commerce and international at commerce and get an integrated space picture at a different agency. not that that would necessarily happen, but it could. if it did happen then we would want our folks over at commerce and probably keep them at dod as well. but, again, this is way early and undetermined at this point. >> thank you, administrator bridenstine. and general hyten, let me ask my last question to you. and it's just been menti
