It takes a rich and diverse set of complex molecules for things like stars, galaxies, planets and lifeforms like us to exist. But before humans and all the complex molecules we’re made of could exist, there had to be that first primordial molecule that started a long chain of chemical events that led to everything you see around you today.
Though it’s been long theorized to exist, the lack of observational evidence for that molecule was problematic for scientists. Now they’ve found it and those scientists can rest easy. Their predictive theory wins!

Last week, in a move that left many perplexed, the nation of India destroyed one of its own satellites. According to a statement made by Prime Minister Narendra Modi, this operation (“Mission Shakti”) was conducted using a new type of anti-satellite missile. With this one act, Modi claimed that India had “established itself as a space power”, effectively joining the United States, Russia and China.
Unfortunately, this demonstration has created a cloud of orbital debris in Low Earth Orbit (LEO). According to a recent statement made by NASA Administrator Jim Bridenstine, this debris poses an “unacceptable” threat to the International Space Station. In this sense, by flexing its muscle as a space power, India may have caused some serious disruption to international efforts in space.

We’ve known for some time that NASA is sending a helicopter to Mars. The vehicle, called the Mars Helicopter, is undergoing flight testing at NASA’s Jet Propulsion Laboratory in California. The little helicopter will make its eventual way to Mars as part of the Mars 2020 Rover mission.
The Mars Helicopter is pretty small, less than 1.8 kg (4 lb). It’s made of lightweight carbon fiber, and other materials like aluminum, silicon, and foil. The version being tested is the actual vehicle that will make the trip to Mars.

A dramatic week in space launcher politics has left NASA’s Space Launch System (SLS) with a vastly reduced launch manifesto and casts doubt on the prospects of future upgrades to the massive launch vehicle.
On Monday the White House’s budget request laid out the administration’s plans for NASA’s coming years. For SLS there were three significant changes.

NASA has shared Opportunity’s final photograph from the surface of Mars. The rover’s final resting place is in Endeavour Crater, and barring any statistically unlikely event, it will sit there for centuries, millennia, or even longer. And instead of a tombstone, we have this final image.

A few hours ago, the SpaceX Crew Dragon splashed down in the Atlantic Ocean, about 200 miles off the coast of Florida. The splashdown is the last act in what has been a successful first flight for the Crew Dragon. The flight, called Demo-1, was launched on March 2nd and spent five days at the International Space Station (ISS).

After more than 10 years of hard work, NASA has reached another milestone. We’re accustomed to NASA reaching milestones, but this one’s a little different. This one’s all about a type of photography that captures images of the flow of fluids.

It’s another milestone for SpaceX as their Crew Dragon spacecraft successfully docked with the International Space Station.
In the early morning of March 2nd, the unmanned Crew Dragon launched from complex 39A at NASA’s Kennedy Space Center in Florida. Then on March 3, at approximately 6:00 AM, the spacecraft successfully docked with the space station. Universe Today had a photographer, Alex Brock, at the launch to capture the action.

Right, magnetars. Perhaps one of the most ferocious beasts to inhabit the cosmos. Loud, unruly, and temperamental, they blast their host galaxies with wave after wave of electromagnetic radiation, running the gamut from soft radio waves to hard X-rays. They are rare and poorly understood.
Some of these magnetars spit out a lot of radio waves, and frequently. The perfect way to observe them
would be to have a network of high-quality radio dishes across the world, all
continuously observing to capture every bleep and bloop. Some sort of network
of deep-space dishes.
Like NASA’s Deep Space Network.

NASA has announced that the SpaceX Crew Dragon capsule is ready for its first demo flight. After discussions with SpaceX, both NASA and Elon Musk’s private space company determined that it was time for Dragon to fly. The date for the flight is March 2nd.
