http://www.spacedaily.com/reports/S...el_Making_Deep_Space_Travel_Possible_999.htmlAccording to a new study, scientists have cracked one of most challenging obstacles to deep space travel: how to ensure that astronauts have enough fuel, air and water for the trip. Their proposed method involves "photo catalysts" that can split or recombine water molecules.
The emptiness of space and the vast distances between locations pose huge and unique challenges to space travel. One of the biggest challenges is the need to either bring everything you'll require with you or to make it along the way.
The basic essentials of fuel, water and breathable air are also some of the hardest to guarantee, since every ounce of weight packed onto the spacecraft has to be moved and protected. What if, instead, there was a method of recycling and recombining them?
The only remaining question is the source of the electricity for the process. In an interesting twist of fate, the day Nature published the study in question was also the anniversary of the day Albert Einstein received a Nobel Prize in 1923 for discovering the process that makes it possible: the photoelectric effect.
Solar panels, also called photovoltaic cells, receive photons in sunlight and convert them into electricity. They are a common source of fuel for space travel as they are far more efficient in space than on Earth, but their utility decreases the further away from the sun you are.
In the past, spacecraft sent toward the outer reaches of the solar system have typically used radioisotope thermoelectric generators, which harness the heat energy released by decaying radioactive materials, as an alternative fuel.
However, newer craft have made use of more powerful and effective photovoltaic systems: The Juno probe, launched toward Jupiter in 2011, was the first to use solar power instead of RTG that deep in space; the Dawn spacecraft, sent to the Asteroid Belt to study the dwarf planets Vesta and Ceres in 2007, used solar power to fuel its ion engine, another first, which generates thrust by ionizing and accelerating gas and which requires electricity to function.
En tiedä yhteistyöstä mutta tänä vuonna Kiinasta on jo enemmän laukaisua kun Yhdysvalloista tai venäjältä. Osa kaupallisia sateliittilauksusuja.No ehkä ainoa hyvä asia on että Kiina aikoo tehdä paljon yhteistyötä heidän kanssa. Ehkä he huolivat Intian jossain välissä tähän pumppuun kanssa.
https://spectrum.ieee.org/tech-talk...d-on-a-diamondshaped-asteroid-900-meters-wideThe Japan Space Exploration Agency (JAXA) launched its second asteroid probe, the Hayabusa2, in December 2014. The aim: learning more about how the solar system and possibly life on Earth originated. After meeting up with Ryugu, its target asteroid, on 27 June, Hayabusa2 is now decreasing its altitude (to roughly 5 kilometers above the surface) in order to carry out medium altitude observation. By late August, JAXA will decide where on the space rock’s surface Hayabusa2 will land. The agency intends to have it touch down in a September-October time frame.
http://www.spacedaily.com/reports/R..._Develops_Concept_of_Reusable_Rocket_999.htmlRussia's Khrunichev State Research and Production Space Center has finished the development of a blueprint for Russia's reusable launch vehicle and sent the relevant materials to Roscosmos' Central Research Institute of Machine Building (TsNIIMash) for assessment, the Khrunichev center's press office told Sputnik.
"The materials on reusable subjects were sent to TsNIIMash. They should study them and provide their expert opinion," a spokesperson for the space center said.
Earlier it was reported that the Khrunichev Center is carrying out design research works on carrier rockets with reusable first stage. Various schemes to reuse rockets are being considered, including the vertical landing, the parachute-jet rescue system and the winged scheme of the reusable part of the rocket.
This is not the first project in the field of reusable rockets being developed in Russia. On June 4, Deputy General Director for Project Management of Ilyushin Aviation Complex Dmitry Gerasimov said that Russian manufacturers have developed several configurations for the first national reusable space rocket.
Moscow-based Foundation for Advanced Research Projects (FPI) then said that tests of the rocket are scheduled for 2022. The rocket will be capable of carrying up to 600 kilograms (over 1,300 pounds) of payload on the sun-synchronous orbit. According to preliminary calculations, the cost of bringing payload on orbit will be one and a half or two times cheaper than using ordinary rockets of such a class.
At present, reusable rocket carriers are created only by two US private companies - SpaceX and Blue Origin.
Enää pitää löytää 250 000 dollaria lippua varten.
Virgin Galactikin Space Ship Two VSS Unity teki koelennolla uuden korkeusennätyksen. 42 sekunnin poltto rakettimoottorilla nosti aluksen 52 kilometrin korkeuteen. Nopeutta nousuvaiheessa 2,47 Machia.

Johonkin vähän päälle sataan kilometriin varmaankin.
180 km, jos haluaa lähimmälle kiertoradalla. Ei riitä että pääsee avaruuteen
Joo, tarkotinkin nimenomaan noita ballistisia hyppylentoja.
