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.

Curiosity Crashed, but it’s Working Fine Again. NASA Won’t Have to Send Astronauts to Turn it off and Back on Again.

In 2012, NASA’s Curiosity rover landed in the Gale Crater on Mars and began exploring for clues about the planet’s past and subsequent evolution. Since 2014, it has been investigating Mount Sharp (aka. Aeolis Mons) – the central peak within Mars’ Gale Crater – in the hopes of learning more about Mars’ warm, watery past (and maybe find signs of past life!)

On February 15th of this year (Sol 2320), Curiosity gave mission controllers a bit of a scare when it suffered a technical glitch and automatically entered safe mode. Luckily, as of Thursday, Feb. 28th, Curiosity’s science team reported that after getting the rover back online and running a series of checks, the rover is in good shape and ready to resume normal science operations.

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.

X-rays Might be a Better Way to Communicate in Space

In the coming years, thousands of satellites, several next-generation space telescopes and even a few space habitats are expected to be launched into orbit. Beyond Earth, multiple missions are planned to be sent to the lunar surface, to Mars, and beyond. As humanity’s presence in space increases, the volume of data that is regularly being back sent to Earth is reaching the limits of what radio communications can handle.

For this reason, NASA and other space agencies are looking for new methods for sending information back and forth across space. Already, optical communications (which rely on lasers to encode and transmit information) are being developed, but other more radical concepts are also being investigating. These include X-ray communications, which NASA is gearing up to test in space using their XCOM technology demonstrator.

InSight has Placed its Heat Probe on the Martian Surface. The Next Step is to Jackhammer Down 5 Meters and Hope it Doesn’t Encounter a Large Rock

NASA’s InSight lander has finally placed its heat probe on the surface of Mars. The Heat Flow and Physical Properties Package (HP³) was deployed on February 12th, about one meter away from SEIS, the landers seismometer. Soon it’ll start hammering its way into the Martian soil.

Another Enormous Crater Found Under the Ice in Greenland

A glaciologist has discovered another enormous impact crater under more than a mile of ice in Greenland. This is on the heels of the November 2019 discovery of an impact crater in the same area under the Hiawatha Glacier. The November discovery was the first-ever crater found under ice on Earth.

This is Kepler’s Final Image

On October 30th, 2018, after nine years of faithful service, the Kepler Space Telescope was officially retired. With nearly 4000 candidates and 2,662 confirmed exoplanets to its credit, no other telescope has managed to teach us more about the worlds that exist beyond our Solar System. In the coming years, multiple next-generation telescopes will be deployed that will attempt to build on the foundation Kepler built.

And yet, even in retirement, Kepler is still providing us with impressive discoveries. For starters, NASA started the new year by announcing the discovery of several new exoplanets, including a Super-Earth and a Saturn-sized gas giant, as well as an unusually-sized planet that straddles these two categories. On top of that, NASA recently released the “last lighty” image and recordings obtained by Kepler before it ran out of fuel and ended its mission.

Here it is, the high resolution photo of MU69 we’ve all been waiting for.

On December 31st, 2018, NASA’s New Horizons mission made history by being the first spacecraft to rendezvous with a Kuiper Belt Object (KBO) named Ultima Thule (2014 MU69). This came roughly two and a half years after New Horizons became the first mission in history to conduct a flyby of Pluto. Much like the encounter with Pluto, the probe’s rendezvous with Ultima Thule led to a truly stunning encounter image.

And now, thanks to a team of researchers from the John Hopkins University Applied Physics Lab (JHUAPL), this image has been enhanced to provide a more detailed and high-resolution look at Ultima Thule and its surface features. Thanks to these efforts, scientists may be able to learn more about the history of this object and how it was formed, which could tell us a great deal about the early days of the Solar System.

Still no Word from Opportunity

Could this be the end of the Opportunity rover? There’s been no signal from the rover since last summer, when a massive global dust storm descended on it. But even though the craft has been silent and unreachable for six-and-a-half months, NASA hasn’t given up.

When Opportunity landed at Meridiani Planum on Mars in January 2004, it’s planned mission length was only 90 days. Since that day, which seems so long ago now, 15 years have passed, and over one billion people have been born on Earth. Six months ago, the rover stopped working, maybe for good. So by every measure, Opportunity has been a stunning success.
