The Gemini Planet Imager, a new telescopic instrument designed to find, image, and study faint, young planets orbiting bright stars, has discovered its first exoplanet: a young Jupiter-like planet called 51 Eridani b which orbits the star 51 Eridani, about 100 light-years away. Thought to be similar to a younger version of Jupiter, it should help astronomers learn more about how planetary systems form.
In what may be a significant step toward the seemingly far-off goal of sending a rover to the surface of Venus, NASA has awarded two grants totalling $245,000 to a semiconductor technology firm to design complex integrated circuits which could withstand the extremely harsh environment on this neighboring world.
For several decades, Mars has been a busy place, with orbiters, landers, and rovers providing unprecedented views of the Red Planet. Another exciting possibility which has yet to be realized is an airplane, which could soar through the atmosphere, showing Mars in a way not possible before – closer than an orbiter, but unique from a lander or rover stuck on the surface. NASA is now testing just such a concept, the first Mars airplane which could fly in the Martian skies in the 2020s.
The next NASA mission to Mars, the InSight lander, will include some additional experimental technology: the first deep-space CubeSats. Two small CubeSats will fly past the planet as the lander is descending through the atmosphere; this will be the first time CubeSats have been used in an interplanetary mission.
With so much attention now on the rovers and spacecraft at Mars, Saturn, Ceres, comet 67P/Churyumov-Gerasimenko, and, soon, Pluto, it may seem like Earth’s closest planetary neighbor Venus has been forgotten again. But no, Venus is still very much on the minds of researchers who are busy developing a concept airplane which could cruise for years in the hellish planet’s atmosphere.
The search for exoplanets may one day get a lot more glittery. It sounds a bit like science fiction, but a new NASA proposal called Orbiting Rainbows would use glitter-like materials to help image some of those far-away worlds, which could enable high-resolution imaging at a fraction of the cost.
Who wouldn’t want to go explore an alien sea? It seems that NASA would certainly like to, and the agency has unveiled a new submarine design to hopefully do just that one day. The submarine would be sent to Saturn’s largest moon, Titan, to dive into one of the large liquid methane seas on the moon’s frigid surface; such a mission idea may sound like science fiction, but it’s not, and would be the first ever to explore a sea on another world which is both Earth-like in some ways, yet utterly alien in others.
Addendum: press release is now available here.
The images being taken by the Curiosity rover on Mars have been amazing enough so far, but with one thing in common – they are all daytime images. Now, though, Curiosity has taken its first nighttime photos! These initial images were taken a couple of days ago, on sol 165. This is also the location where Curiosity will soon do its first drilling.
Using lasers to communicate at planetary distances is something that may sound like sci-fi, but it is a real technology being developed by NASA as a means of communicating with spacecraft faster and more efficiently than can be done now.
As technology advances, a lot of the gadgets and other things we use keep getting smaller, lighter and thinner. Now that trend may soon be taken to another extreme – small robotic space explorers which in turn use a miniscule power source – bacteria…
