DRAGON: no, treba se toho chteji dozit, nez zemrou. Ale jinak jsem spise narazel na to, ze pokud sondu urychli na 1/5 c .. tak ta sonda proleti "kolem" cilove destinace v tak vysoke rychlosti, ze pokud vubec stihne poridit "fotku" .. rekneme 10 MPix .. tak to bude rychlosti rekneme 10 B/s, posilat dalsich skoro 20 let :D

An Interesting SETI Candidate in Hercules

An international team of researchers has announced the detection of “a strong signal in the direction of HD164595” in a document now being circulated through contact person Alexander Panov. The detection was made with the RATAN-600 radio telescope in Zelenchukskaya, in the Karachay–Cherkess Republic of Russia, not far from the border with Georgia in the Caucasus.

The signal was received on May 15, 2015, 18:01:15.65 (sidereal time), at a wavelength of 2.7 cm. The estimated amplitude of the signal is 750 mJy.

No one is claiming that this is the work of an extraterrestrial civilization, but it is certainly worth further study. Working out the strength of the signal, the researchers say that if it came from an isotropic beacon, it would be of a power possible only for a Kardashev Type II civilization. If it were a narrow beam signal focused on our Solar System, it would be of a power available to a Kardashev Type I civilization. The possibility of noise of one form or another cannot be ruled out, and researchers in Paris led by Jean Schneider are considering the possible microlensing of a background source by HD164595. But the signal is provocative enough that the RATAN-600 researchers are calling for permanent monitoring of this target.

Looking for Life on Saturn's Moon Enceladus: Send a Flyby or Lander?

A conference called "Enceladus and the Icy Moons of Saturn" was held here from July 26 through July 29, bringing together top experts to the first major international conference devoted specifically to Enceladus and Saturn’s family of super-chilly moons.

Cassini discovered that the Saturn satellite Enceladus is a mini-world of active jets — geyser-like phenomena that blast out water vapor and ice particles from the huge, salty ocean that lies beneath the moon's icy crust. Cassini flew by Enceladus for the last time in October 2015. (After almost 20 years in space, the $3.2 billion Cassini mission is set to end in September 2017.)

The information Cassini gathered during these passes strongly suggests that Enceladus harbors a large ocean beneath its icy shell, and that this ocean might be able to support life as we know it, mission team members have said. (The ocean stays liquid because of "tidal heat" created by the tug of Saturn's powerful gravity.)
"Enceladus possesses habitable locales, but does it contain life?" Esposito told Space.com.
Scientists around the world are considering a variety of ways to tackle this question.

Vše o objevu exoplanety u Proximy Centauri | Exoplanety.cz
http://www.exoplanety.cz/2016/08/24/exoplaneta-proxima-b/

Astronomové objevili pomoci spektrografů HARPS a UVES exoplanetu u nejbližší hvězdy od Slunce – Proximy Centauri alias Alfa Centauri C.

Exoplaneta Proxima b (Alfa Centauri C b) má hmotnost 1,27 Země a oběžnou dobu 11,2 dní. Pozor! Jedná se o dolní odhad hmotnosti. Její přesná hodnota je závislá na sklonu dráhy vůči nám.

Základní údaje o planetě Proxima b

- Hmotnost (minimální): 1,27 (1,1-1,46) Země
- Oběžná doba: 11,2 dní
- Změny radiálních rychlostí: 1,38 m/s
- Velká poloosa dráhy: 0,0485 AU
- Výstřednost: menší než 0,35
- Oslunění (množství záření od hvězdy): 65 % (ve srovnání se Zemí)
- Rovnovážná teplota: 234 Kelvinů (teplota na povrchu bez vlivu atmosféry)

Exoplaneta byla objevena pomoci metody měření radiálních rychlostí. Nevidíme ji tedy přímo ale pozorujeme pouze její vliv na mateřskou hvězdu.

Samotná hvězda Proxima Centauri je hodně malá. Má hmotnost 12 % Slunce, velikost 14 % Slunce a vyzařuje 0,16 % záření. Hvězda se nachází v souhvězdí Kentaura na jižní obloze, kde byste ji ale pouhým okem neviděli. Přestože je za humny, s ohledem na její typ a zářivost, je její jasnost pouhých 11 mag, takže k jejímu pozorování byste se museli vybavit hvězdářským dalekohledem.

Už se to blíží! :)

NASA's Asteroid Redirect Mission Completes Robotic Design Milestone
https://www.nasa.gov/feature/nasas-asteroid-redirect-mission-completes-robotic-design-milestone

Following a key program review, NASA approved the Asteroid Redirect Mission (ARM) to proceed to the next phase of design and development for the mission’s robotic segment. ARM is a two-part mission that will integrate robotic and crewed spacecraft operations in the proving ground of deep space to demonstrate key capabilities needed for NASA’s journey to Mars.
