Earth becomes a laboratory for the study of distant worlds

The study of exoplanets could help scientists answer big questions about our place in the universe, and whether life exists beyond Earth. But, these distant worlds are extremely faint and difficult to image directly. A new study uses Earth as a stand-in for an exoplanet, and shows that even with very little light -- as little as one pixel -- it is still possible to measure key characteristics of distant worlds.

Diving deep into the search for life

Off the coast of Hawaii’s Big Island and more than 3,000 feet beneath the ocean surface lie the warm, bubbling springs of a volcano — a deep-sea location that may hold lessons for the search for extraterrestrial life. Here, NASA and its partners are blending ocean and space exploration, with a project called SUBSEA, short for Systematic Underwater Biogeochemical Science and Exploration Analog.

A magnetic power struggle at the heart of solar eruptions

  A dramatic magnetic power struggle at the Sun’s surface lies at the heart of solar eruptions, new research using NASA data shows. The work highlights the role of the Sun’s magnetic landscape, or topology, in the development of solar eruptions that can trigger space weather events around Earth.

Studying middle-aged Sun by tracking motion of mercury

Like the waistband of a couch potato in midlife, the orbits of planets in our solar system are expanding. It happens because the Sun’s gravitational grip gradually weakens as our star ages and loses mass. Now, a team of NASA and MIT scientists has indirectly measured this mass loss and other solar parameters by looking at changes in Mercury’s orbit. The new values improve upon earlier predictions by reducing the amount of uncerta...

Powering up human reach for the Red Planet

NASA and its partners will host a news conference at noon EST (9 a.m. PST) Thursday, 18th January, at the National Atomic Testing Museum in Las Vegas, to discuss a recent experiment involving a new power source that could provide the safe, efficient and plentiful energy needed for future robotic and human space exploration missions. Audio of the news conference and presentation slides will stream live on NASA’s website.

NASA to hold satellite servicing tech transfer industry day

  We have lived in a generation of 'one and done' spacecraft, up until now. Barring a few notable exceptions, spacecraft launch alone, operate alone and are decommissioned alone. In an average year, several billion dollars’ worth of satellites that could be refueled or repaired are retired because there is no way to service them in space.

Discovering the eighth planet circling distant star

Our solar system now is tied for most number of planets around a single star, with the recent discovery of an eighth planet circling Kepler-90, a Sun-like star 2,545 light years from Earth.

Mars mission investigates habitability of distant planets

How long might a rocky, Mars-like planet be habitable if it were orbiting a red dwarf star? It's a complex question but one that NASA's Mars Atmosphere and Volatile Evolution mission can help answer. "The MAVEN mission tells us that Mars lost substantial amounts of its atmosphere over time, changing the planet's habitability," said David Brain, a MAVEN co-investigator and a professor at the Laboratory for Atmospheric and Space Physics at the...

Mars 2020 mission will test supersonic parachute

A NASA Mars rover mission set to launch in 2020 will rely on a special parachute to slow the spacecraft down as it enters the Martian atmosphere at over 12,000 mph (5.4 kilometers per second). Preparations for this mission have provided, for the first time, dramatic video of the parachute opening at supersonic speed. The Mars 2020 mission will seek signs of ancient Martian life by investigating evidence in place and by caching drilled sample...

Studying invisible magnetic bubbles in outer solar system

Space may seem empty, but it's actually a dynamic place populated with near-invisible matter, and dominated by forces, in particular those created by magnetic fields. Magnetospheres - the magnetic fields around most planets - exist throughout our solar system. They deflect high-energy, charged particles called cosmic rays that are spewed out by the Sun or come from interstellar space. Along with atmospheres, they happen to pro...

NASA scientists search for exoplanet atmospheres

Some exoplanets shine brighter than others in the search for life beyond the solar system. NASA research proposes a novel approach to sniffing out exoplanet atmospheres. It takes advantage of frequent stellar storms—which hurl huge clouds of stellar material and radiation into space—from cool, young dwarf stars to highlight signs of habitable exoplanets.

3D printed rocket engine part made with two different alloys

Engineers at NASA's Marshall Space Flight Center in Huntsville, Alabama, tested NASA's first 3D printed rocket engine prototype part made of two different metal alloys through an innovative advanced manufacturing process. NASA has been making and evaluating durable 3D printed rocket parts made of one metal, but the technique of 3D printing, or additive manufacturing, with more than one metal is more difficult.

James Webb Space Telescope completes GSEG-1 test

NASA called, and the Webb telescope responded. NASA's James Webb Space Telescope recently completed its Ground Segment Test Number 1 (GSEG-1), for the first time confirming successful end-to-end communication between the telescope and its mission operations center. GSEG-1, which completed on June 20, tested all of the communications systems required to support the telescope's launch, commissioning and normal operations once it is in orbit.

Solar eclipse could help understand Earth’s energy system

It was midafternoon, but it was dark in an area in Boulder, Colorado on Aug. 3, 1998. A thick cloud appeared overhead and dimmed the land below for more than 30 minutes. Well-calibrated radiometers showed that there were very low levels of light reaching the ground, sufficiently low that researchers decided to simulate this interesting event with computer models. Now in 2017, inspired by the event in Boulder, NASA scientists will explore the moon...
