Rockets need to carry more of their payload as fuel if they’re going to gain higher velocities.

Sun does not go dark at night it is just on the other side of the Earth and we can't see it - but it is daylight somewhere all the time. At … Although we can emit rocket towards the sun, but it's too expensive to make a rocket: So I think maybe we can recycle the rocket, at first, the rocket is send out with a very fast speed, so give back a big force to the earth. Hours before the rise of the very star it will study, NASA’s Parker Solar Probe launched from Florida Sunday to begin its journey to the Sun, where it will undertake a landmark mission. So any rocket to the sun or any other star would melt just like being shot into boiling lava. The most solid angle the sun can take up is $2 \pi$, and the other half of your field of view is, indeed, cold. NASA will fly a spacecraft directly into the Sun in a bid to unlock the secrets of solar storms that plays havoc with satellites and power supplies, the agency has announced. Wearing a nearly 5-inch coat of carbon-composite solar shields, NASA's Parker Solar Probe will explore the sun's atmosphere in a mission that begins in the summer of 2018. To get to the Sun, they sent the probe to Jupiter in order to slingshot it into a few polar flybys of the Sun, each spaced out by about six years. The SunRocket can make hot water for drinking, cooking, washing, re-hydrating freeze-dried foods all from just sunlight.It can also melt snow to drinking water and kill water borne bacteria through heat treatment. There you go, you've thrown a year's worth of trash into the sun... at a cost of just $330 quadrillion. The spacecraft will transmit its first science observations in December, beginning a revolution in our understanding of the star that makes life on Earth possible. CAPE CANAVERAL, Fla. — This weekend, on Saturday (Aug. 11), NASA's Parker Solar Probe will boldly go where no spacecraft has dared go before: up close and personal with the sun. So if we think, actually, it would take 6 million rocket launches to get all the plastic from just one year up towards the moon, not even to the sun. $\begingroup$ Yes, you would effectively have mirrors on the sun-side of things, but as I understand radiative physics, being close to the sun doesn't mean that you have to thermalize to its temperature. This is why a volunteer collective of scientists and engineers called the Initiative for Interstellar Studies wants to send a rocket to check it out. So to get a rocket to fall into the sun, we would need to launch it with enough energy to accelerate to 65,000 mph in the opposite direction of Earth's orbit. To get them from there to the sun, you need to multiply the cost by at least 10. A senior NASA official sitting at the table, Johnson Space Center Director Mark Geyer, responded, "It's a good question about the rocket." But it would be a lot more complicated than landing a probe on Comet 67P/Churyumov-Gerasimenko - and that was a very complicated business . With the planet’s motion essentially canceled out, the spacecraft can surrender to the sun’s gravity and begin to fall toward it. And then, we let the rocket slowly comes back to the earth, and re-send it again: Even at night. Last month, Earthling had launched two spacecrafts to explore Mars – the Russian Phobos-Grunt with China Yinghuo-1 piggybacking and NASA Mars Science Laboratory Curiosity.Curiosity had a successful launch and now is on the way to Mars, but unfortunately for Phobos-Grunt, the engine of its Fregat upper stage failed to ignite and it is now stuck in low-Earth orbit. Given that one of our most dangerous forms of waste is nuclear in nature, it would be a logical choice to send shooting off towards the Sun. A Falcon Heavy can carry more than 54 tonnes to Low Earth Orbit, but only 2.9 tonnes to Pluto. The EVE sounding rocket supports the calibration of EUV measurements taken by spacecraft to make sure the data they provide are accurate. And if we think there are only about 85 rocket launches a year - that's about 70,000 years it would take just to shift last year's plastic. The SunRocket portable solar water thermos heats, boils and sterilizes water from sunlight.Reflective panels make this on-the-go tool super portable and robust. Firstly, as we have seen in many rocket launches (most famously the Challenge disaster in 1986), tragedies can happen during any attempt to leave our atmosphere.
