comet in two thousand and five and there is even a mission currently being planned between the european space agency and nasa to test this technology on small asteroid so how much time would space agencies need to prepare and launch an asteroid deterring spacecraft into our bit even small space missions take years of approval yes and if you were actually to have a good chance of deflecting an asteroid successfully you really want five to ten years at a bare minimum you really want more than that if you can in fact the earlier you do such a thing the easier the deflection is which makes sense right the further away the thing is from hitting you the less you need to change its trajectory to make it miss the earth so anyway we can be sure that it gets the job done. the way you do you guarantee that in asteroid deflection mission is successful is that you you you fly multiple spacecraft as backups you know we do this in we have spec up systems for aircraft for spacecraft and things like that and you can think of multiple missions as being backups to each other so if it's really super critical you know a

today the european space agency turned these off. but the data gathered by the tiny probe represents a giant leap forward, helpingscientists build space instruments that detect rotational waves, giving them a better look at the university they've ever had. -- uniniverse then they've ever had before. reporter: super powerful telescopes allow astronomers to look back in time, and this is what they see. a viewew deep into the past. it shows what the universe looked like about 400,000 years after it was born. long before the first stars s ad galaxies were formed. how our universe was created and what happened directly afterwards cannot be researched using conventional telescopes. as the big bang was happening, gravitational waves were formed, and they are still vibrating in space. and these very gravitational waves are what opens the door to a distant world. albert einstein described these waves more than 100 years ago with his general theater of -- theory of relativity. they are created, for example, when black holes melt or stars explod

one of the most challenging to date. 0ur science correspondent rebecca morelle is at the european space agency'see the spacecraft before it blasts off into space. it is called beppe columbo and is heading to mercury, the smallest planet in the solar system and the one closest to the sun. it has been designed to withstand extremes, to get to mercury it must travel towards the sun and that means facing intense radiation and heat. the surface of mercury, it can reach 450 celsius, hot enough to melt lead. that is one of the reasons there is this special white blanket covering it, to help deal with this really hot glare. i have been taken ona tourof really hot glare. i have been taken on a tour of the spacecraft, that is the propulsion unit at the base. it will be tricky because it will be fighting against intense gravitational pull of the sun and the engines will have to break as it travels and then that it gets jettisoned away once it arrives and you have to spacecraft in one. in the middle, this bit has been built bailey european space agency and it is going to study the surface of mercury and als

this story as capsule right now let's take a look this is now says randy bresnik this is the european space agency these. are so. to speak. it's it's been good to see. the space is literally staking but it might be right now that a guy who following in the trails of say many incredible human accomplishments this started out right here with the baikonur cosmodrome from being first man in space you were guarding one nine hundred sixty one to the first woman in space and of course the first space will call starting here at the very same ball its. president trumps announced that transgender people will not be allowed to serve in the u.s. may be cited the tremendous medical costs is one reason behind the move next in column open takes a look at how the pentagon spends taxpayers' money. donald trump recently announced that transgender people will not be able to serve in the u.s. armed forces in any capacity he says this is being done in order to save money now the decision has been widely regarded as controversial by some americans we decided to ask people here in new york city what they thought was a g

up on those detections so there is a telescope launching next year from nasa also from the european space agency and partially the canadian space agency the james webb space telescope and that will be able to give us some very preliminary very sketchy early looks at some of the most promising tantalizing potentially habitable planets around the very nearest stars to us but if we really want to get a better sample with really want to be thorough in our search we need to look closer than just a handful of stars we need to look at stars that are within one hundred light years or a thousand light years of us a much bigger bubble of space to do that you need a much bigger and more sophisticated space telescope that's probably going to be very expensive on the order of how much web costs which at last i checked was little more than eight billion dollars so. it's not sure there is the money or the will to to build those sorts of things in the in the near the near term time frame so that's kind of depressing but you know maybe we will get a signal from some star some planet via radio or laser pulse and

our science correspondent rebecca morelle has spent the day at the european space agency's test centre closest to the sun. covered in craters, towering cliffs and ancient volcanoes, until now, it has been little explored. a major new mission is set to change that. this is the spacecraft cold bepicolombo, named after a famous italian scientist. it has taken nearly a decade to build. it is only when you get up close that you really get a sense of the size of this huge piece of kit. and this is a spacecraft built to withstand extremes. to get to mercury, it has to travel towards the sun, and that means dealing with intense radiation and heat. on the surface of mercury, temperatures can reach a50 celsius, and that's hot enough to melt lead. its launch will take place next year. this is probably one of the most challenging missions we have ever undertaken. it's the long journey to get there and then we have to deal with heat when we get close to the the sun. but mercury is a tiny, enigmatic little world, which has so much to tell us about the formation of our solar system. bepicolombo's jou

the problem we're having right now, major partners are european space agency, which are great, wonderfulple, wonderful engineers, don't have very much money. the russians space agency, again lots of experience and in orbit,. lots of experience with life-support on large rockets but really struggling financially. most of their problems are shelved at the moment. we need to pay them to do it. of course partner of choice would be china. they have flown in orbit. they have launched two small space station. they will launch a third that will be bigger. they have gone great guns. they are landing probes on moon. sending them to mars. they will send astronauts to the moon we think in the 2020s. we have this thing called itar, a set of laws designed to prevent intellectual property being transferred to what could be hostile powers, depending on how you read itar almost everybody but hawaii. it is really frustrating. there is a lot of limitations what you can do internationally because of those regulations. so there is a lot of people in nasa that are trying to figure out how to work past this. i
