Event Horizon

Here you go, space nerds: the first ever image of the event horizon of a black hole! The supermassive black hole at the center of galaxy M87 is 54 million light-years from earth and has a mass of 6.5 billion suns.

The close-up image is from the Event Horizon Telescope, the wide-field view from the Chandra X-ray Observatory.

Early analysis suggests the observations are consistent with Einstein's Theory of General Relativity (some were hoping they would conflict, because having to redo all the theories is kind of exciting).

Crew Dragon

LIFTOFF! The next big leap in a new chapter of U.S. human spaceflight systems has begun. @SpaceX’s #CrewDragon demo flight is the 1st commercially-built & operated American spacecraft designed for humans to dock at the @Space_Station. NASA: “Today’s successful launch marks a new chapter in American excellence, getting us closer to once again flying American astronauts on American rockets from American soil."

For this demo launch, Crew Dragon is staffed with a sensor-laden dummy named “Ripley.” The capsule will arrive at the ISS on Sunday, where it will attempt its first autonomous docking (previous non-crew Dragon capsules have been snagged and guided in by an arm on the ISS controlled by astronauts on board).

SPHEREx Announced

NASA Selects New Mission to Explore Origins of Universe:

The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission is a planned two-year mission funded at $242 million (not including launch costs) and targeted to launch in 2023. SPHEREx will survey the sky in optical as well as near-infrared light which, though not visible to the human eye, serves as a powerful tool for answering cosmic questions. Astronomers will use the mission to gather data on more than 300 million galaxies, as well as more than 100 million stars in our own Milky Way.

A Celebration of Opportunity

The NASA press conference was a beautiful, heartfelt celebration of the 15 years of Opportunity's mission and a look to the future of Mars exploration.

Over the last 9 months, the team sent over 1,000 recovery commands to try and wake Opportunity up, ultimately to no avail. The last message Opportunity sent translated as “My battery is low and it is getting dark.” 🥺 Amidst a month-long, record-setting dust storm, it was simply too cold and too dark for too long.

Now the internet is overflowing with personal tributes, and more than a few tears. Here are a few, as well as some images and infographics:

XKCD Comic "Opportunity":

A comic with a happy ending, one day:

More hope for a reunion in the future: “And in 200 years time the little rover will awaken to someone cleaning and repairing it and fitting new batteries, and it'll roll outside and look out over the city of the same name, its home.”:

Beautiful thoughts from Scott Maxwell, who relayed commands to Opportunity for years:

Ad astra to Opportunity, the finest planetary rover we’ve ever known:

I'm not crying, you're crying. Okay, fine, we're all crying. 😭

Opportunity Update

NASA will hold a press conference Wednesday at 2PM EST to share the results of its efforts to reestablish contact with Opportunity. All indications are that it won't be good news, and may very well mark the end of the mission.

It's been 9 months since communication with the rover was lost during a massive Mars dust storm.

Whatever happens, here's a beautiful piece about Opportunity and some of the lives it's touched by Shannon Stirone:…/its-time-to-say-goodbye-to-our-beloved…. Expect a lot more pieces like this to be posted in coming days.
