Saturn’s moon Enceladus may have curtain eruptions instead of jets

Saturn’s moon Enceladus may have curtain eruptions instead of jets

NASA has revealed that what have appeared to be geysers on Saturn’s moon Enceladus may, in fact, be “curtain” eruptions — basically long meandering eruptions that form wall-like structures down the moon’s surface. These eruptions are composed of ice and vapor, and can measure in at hundreds of miles in length. They have appeared to be geysers due to optical illusions based on the viewing angle and such. In a video, available after the jump, NASA shows how these optical illusions may work.

Russian cargo ship to fall to Earth Friday morning

Russian cargo ship to fall to Earth Friday morning

Russian spacecraft, Progress 59, encountered a glitch last week before it could complete its mission to resupply the ISS. The error left the cargo ship unable to dock with the ISS. The spaceship is currently spinning out of control and hurtling toward Earth--Not to worry, the craft shouldn't actually impact Earth. Most of it will burn up from intense heat as it re-enters the atmosphere. The three-ton payload of supplied will burn up in its demise. The ship, and everything on it have been written off as a total loss. It is likely to fall to earth early Friday morning, U.S. time.

NASA’s new radar detects heartbeats, saving 4 lives in Nepal

NASA’s new radar detects heartbeats, saving 4 lives in Nepal

The latest tech from NASA just saved the lives of four people trapped in the rubble left from the recent earthquake in Nepal. NASA's FINDER (Finding Individuals for Disaster and Emergency Response) located people by using a microwave radar that could sense and then locate their heartbeats. The prototype devices are a joint effort from NASA and the U.S. Department of Homeland Security's Science and Technology Directorate. Weighing in at the size of a suitcase, two of the devices were brought to aid the humanitarian effort in Nepal.

Astronomers discover real Galaxy Far, Far Away

Astronomers discover real Galaxy Far, Far Away

If George Lucas was a prophet with Star Wars, this week's galaxy discovery might be what he was talking about. A set of scientists have used a set of three different telescopes to capture and calculate the age of the galaxy they call EGS-zs8-1. This galaxy is the furthest away from Earth that any galaxy has ever been discovered. The first image you're seeing in this article (minus the TIE fighter), was captured by NASA's Hubble space telescope back in 2013 and has only just now seen itself the subject of a paper that claims it as our most distant galaxy neighbor.

SpaceX’s to fly Dragon V2, testing escape protocol with a dummy

SpaceX’s to fly Dragon V2, testing escape protocol with a dummy

SpaceX will be testing its Dragon V2 spacecraft on May 6th, specifically assessing the capsule's escape system that could save lives during its eventual manned missions. There is no change of humans coming to harm during this test mission because the only "person" going up with the capsule is Buster, the dummy. He'll ride almost one mile high as the rocket launches from Cape Canaveral, Florida. The capsule will then parachute from its apogee, into a splash-down landing in the Atlantic.

NASA Messenger mission comes to an end, crashes into Mercury

NASA Messenger mission comes to an end, crashes into Mercury

After ten years in space, NASA's Messenger probe purposefully crashed on Mercury. The probe spent four years in a strictly elliptical orbit, using boosts of power from its engine every couple of months, before it finally ran out of fuel. After orbiting Mercury 4,104 times, NASA decided to purposefully crash the probe into the planet's surface using a string of precisely modeled manuevers. When Messenger finally crashed, it hit Mercury at 8,750 mph (14,000 kph) which is about 12 times the speed of sound on earth.

Pluto no longer just “a point of light”

Pluto no longer just “a point of light”

We're approaching Pluto as we speak. NASA's New Horizons probe is headed towards the most controversial of our planetary siblings, and this week they've shown some of the closest images we've ever bore witness to in the history of humanity. According to New Horizons principal investigator Alan Stern, of the Southwest Research Institute in Boulder, Colorado, "[these images] are just a little bit better than anything that's ever been obtained in history." Details are inbound. Details like a possible polar ice cap at one or both ends of this perpetually cold planetary body.

NASA’s New Horizons highlights possible Pluto polar cap

Pluto may have a polar cap, NASA has said, something that is based on data from the space agency’s New Horizons spacecraft. NASA released a bunch of information graphs yesterday, as well as images and animations taken by the spacecraft of Plus and its moon Charon. The images were snapped 13 times over the course of nearly seven days, having taken place from April 12 to April 18 from a distance of approximately 69 million miles. Shown in some of the images is a bright spot that may indicate a polar cap.

AstroGro: a modular 3D-printable garden pod for astronauts

AstroGro: a modular 3D-printable garden pod for astronauts

Humans need to eat every single day, and that requirement puts an extra burden on space missions. Fresh food in space will be a necessity at some point, and dreamers have long developed ideas for how this could be achieved. One team in particular took those day dreams a step further and created a functional pod able to actually grow food, and though it can be used on our own crowded planet, it is made specifically for growing fresh food in space. Among many other things, it is scalable so that it can work in different environments, and it is modular.
