NASA’s Mars helicopter almost ready for take off

The new Mars rover Perseverance, set to launch in July for a February 2021 landing, will be outfitted with its own small helicopter. NASA engineers at Kennedy Space Station recently put the chopper through its paces, marking the last time they'll spin it up before landing on the red planet. From Kennedy Space Center:

The ...

“Old gas blob from Uranus found in vintage Voyager 2 data”

Yes, that is actually Space.com's brilliant headline on this story about a new discovery from data collected in 1986 by NASA's intrepid spacecraft. When the probe neared Uranus (heh heh), it measured the planet's surrounding magnetic field. Recently, NASA scientists Gina DiBraccio and Daniel Gershman analyzing Voyager's old data found a "wobble" in Uranus's magnetosphere ...

NASA’s stunning image of our galactic center

Last July, NASA released this wonderful composite image of the galactic center of the Milky Way.

The central region of our galaxy, the Milky Way, contains an exotic collection of objects, including a supermassive black hole weighing about 4 million times the mass of the Sun (called Sagittarius A*), clouds of gas at temperatures of millions ...

NASA: No, that UFO plainly seen in our space observatory footage isn’t a UFO

NASA's STEREO (Solar TErrestrial RElations Observatory) research platform consists of two orbiting spacecraft that collect stereoscopic data about the sun and the eruptions of magnetized plasma during coronal mass ejections (CMEs). Last month, UFO buffs spotted a strange object in data acquired by STEREO, specifically what appears to be a wheel-shaped UFO. The footage ...

Japanese spacecraft fired cannonball into asteroid

The Japan Aerospace Exploration Agency's (JAXA) Hayabusa2 spacecraft fired a copper cannonball into Ryugu, an 850 meter-wide near-Earth asteroid. The 2 kilogram "Small Carry-on Impactor," a bit larger than a tennis ball, hit the asteroid at approximately 7,200 kilometers/hour and blew out a 14.5 meter wide crater with a depth of .6 meters. After a ...

Physicist Freeman Dyson’s alien megastructure legacy

In 1960 during the early days of the search for extraterrestrial intelligence, theoretical physicist Freeman Dyson, who died last month, wrote an article titled "Search for Artificial Stellar Sources of Infrared Radiation" for the journal Science. He posited that "if extraterrestrial intelligent beings exist and have reached a high level of technical development, one ...

The strange planet where it rains iron

On the planet Wasp-76b, it rains iron. Researchers from the University of Geneva (UNIGE) and colleagues observed the planet, 650 light years from Earth, using the European Southern Observatory's Very Large Telescope in northern Chile. On the planet's "hot side" that faces it star, temperatures can be above 2,400°C. It's a good thing the residents ...

Photos of planet Earth

Pictures of Earth by Planetary Spacecraft is, as you have perhaps already surmised, a collection of photos of our homeworld not taken by human beings.

The image above comes from NASA's Cassini spacecraft. Earth is the little dot to the top left of Saturn, shining through the rings. Read the rest

R&D Roundup: Smart chips, dream logic and crowdsourcing space

I see far more research articles than I could possibly write up. This column collects the most interesting of those papers and advances, along with notes on why they may prove important in the world of tech and startups. This week: crowdsourcing in space, vision on a chip, robots underground and under the skin and ...

NASA won’t be able to talk to Voyager 2 for the next year

For the next year or so, the NASA Deep Space Network's 70-meter-wide (230-feet-wide) radio antenna in Canberra, Australia will have limited functionality is it undergoes critical upgrades. As a result, NASA won't be able to transmit commands 12 billion miles into space to the intrepid Voyager 2 space probe that recently recovered quite beautifully ...
